F 18 - Central Europe Fast-Time Simulation
By Leif Lundqvist (EEC/AMS)
EXECUTIVE SUMMARY
In April of 1997 a first meeting was held for the planned three-state real-time simulation for theinterface between Vienna, Bratislava and Budapest.
On the initiative of DED/4 a slot for a fast-time simulation study to lay the ground for the real-time simulation was allocated and the project was given EEC task number F18.
The first meeting was held in Brétigny in August 1997 between the national representativesand EUROCONTROL representation from DED/4 and EEC.
The scope of the simulation was decided and the working group nominated ATC expertsrepresenting both ACC and APP from all three countries with Leif Lundqvist of the EEC asproject leader.
The objectives agreed for the project were:
• To analyse the current system including SIDs and STARs concerning the TMAinterface between Bratislava - Vienna - Budapest.
• To study the effects of the ARN V3 route network, re-sectorise and, as necessary, re-
align or create new SIDs and STARs to join the new route system. • To study the effects of future traffic increases • To harmonise routes and optimise sectorisation of TMA and ACC sectors irrespective
of National boundaries. • To include the whole area of the three FIRs to properly assess the effects of ARN V3
route network changes in the area. As a basis for the simulation, to represent a normal busy day, the 7th of August 1997 waschosen. The 24 hour traffic sample provided by the three countries was verified by all threestates and consisted of 2928 flights. The results of this fast-time simulation will be consideredwith regards to routing, sectorisation and manning plans for the forthcoming real-timesimulation in Brétigny early 2000. The measurement of workload levels used as an approximate reference 50% over a period ofthree hours, and 70% over a period of one hour as the limit, above which controllers workloadis considered severe. The different organisations and individual exercises simulated sought tofind an even distribution of workload avoiding overload on any sector.

The following exercises were simulated: • Organisation A: (6 exercises) Reference organisation A was based on August 7,1997 traffic, sectors and procedures.Different exercises compared different runway configurations, effect of military co-ordinationswith areas delegated within Vienna FIR, all military sectors open in Bratislava FIR, opensportsfields in Budapest TMA which are used by gliders and parachutists, and different verticalsector splits. • Organisation B: (7 exercises) Re-aligned routes, new SID/STAR systems, enlarged Bratislava TMA and in different exercisescomparing effect of re-routing on certain routes, different upper levels of TMA and differentsectorisation in Vienna FIR. • Organisation C: (2 exercises) Exercises of the forecast traffic level in 2003 with sectorisation based on organisation B. 4100flights appeared in this organisation. • Organisation D: (1 exercise) Organisation C transferred to ARN V3 route network. This organisation changed therelationship between different sectors since a great deal (40-50%) of the traffic in the Budapestsouth (LHCC_S) sector and Vienna South sector (LO_S) sector was re-routed on forecast re-opened routes through former Yugoslavia. The basis for this organisation was the ARN Version3 route network as agreed in May of 1998. CONCLUSIONS AND FINDINGS: • A and B organisations - General for the 1997 studies : In the reference scenarios, (Org. A) the effect on controller workload caused by military co-ordination procedures was tested against closed military sectors. The effect on controllerworkload for the TMA, caused by open sportsfields in LHBP TMA was also assessed.Although an important effect on the workload was found in the concerned sectors of all threeFIRs, it did not have an impact on capacity or put controllers under what could be consideredheavy workload. It was therefore seen as unnecessary to test in future organisations. The B organisation was in part been implemented during the course of the study. The newSID/STAR systems and partial re-routing proved beneficial in the mathematical study. Thisaffected all three countries and was recommended as an early result of the study. Thecombination of simulations and real experience showed this to be a more efficient organisationthan Reference Organisation A.

Different runway configurations tested showed that using Vienna RWY 16 for arriving trafficwas more favourable from a workload viewpoint than the use of RWY 34 for the Vienna TMAsectors. Similarly, for Budapest TMA the use of RWY13L/R proved more favourable than RWY31L/RWY31R. Vienna FIR Testing of different vertical sectorisation was made, and for the TMA the present level, FL 245was found to be the most efficient upper level of Vienna TMA. However it is recommended tosplit the lower TMA sector into two, in order to avoid overloading with the forecast traffic levels.(Ref exercise B1C). It is further recommended to implement a tested re-routing of Viennaarrivals from NW to fly SBG-SNU direct. Testing of alternative routing of inbound traffic from Southeast gave no positive indicationseither way. Combining the East and South sectors proved to be difficult due to the traffic loading. Evenwith vertical splits at FL285 and FL340 overload risks occurred at 2003 traffic levels. Thesectors are therefore recommended to be kept separate. Budapest FIR The 1997 studies showed the workload level for the South sector (LHCC_S) to be above thenormally acceptable measurements, and several other sectors were very close to this limit. Theproposed re-routing of inbound Vienna traffic through Bratislava FIR is believed to have apositive effect, although the number of flights is limited. Another alternative routing DIMLO-BABIT for Vienna inbound traffic increased the load on thealready busy South sector and also gave negative effects on the Vienna en-route sectors. Thisis consequently not recommended. A new outbound routing for Vienna departures into Budapest FIR was tested with southboundheading after border-point ABETI to avoid opposite north-westbound traffic. The re-routingclearly separated the flows of north-westbound and south-eastbound traffic but had no effecton the number of conflicts in the Budapest West sector. For Budapest FIR the existing sectorisation was maintained in the future scenarios andshowed overloading with severe workload in the West, South and East sectors. This will beresolved through the new agreed sectorisation into seven ACC sectors. This new sectorisationplan was never presented as a simulation requirement for the fast-time simulation and wasconsequently never simulated. Budapest TMA was tested with only one sector and theforecast indicated severe workload (above 50%) for the busiest three hour period. Splitting theTMA into two sectors will become necessary.

Bratislava FIR The main question for Bratislava FIR was the extent of Bratislava TMA and its effect on ACCsectors. The studies lead to a recommendation to raise the upper limit of the TMA to FL195instead of FL105. The increase in traffic would not pose a problem to the workload in the TMAand all co-ordination between Vienna TMA and Bratislava FIR could be handled directly byBratislava TMA sector. The increased volume of Bratislava TMA relieves the lower ACC sector which opens thepossibility of raising the limit to the middle sector and leaves more capacity for further growthwithout increasing the number of ACC sectors. • Future organisation C Traffic cloned by 40% to indicate the forecast traffic level for 2003 in accordance with forecastfigures for the area published by EUROCONTROL DED/4 in 1997. Cloning of traffic reproduced existing flights in 40% of the cases and the new flights appearedon the same routes and at the same levels as the “parentflights” in the 1997 scenario. Theentry time was offset by up to 180 minutes. Vienna FIR Severe workload results in sectors East upper (EU), North upper (NU) and TMA low (TL). Budapest FIR The present sectorisation was retained and with the traffic increase severe workload was theresult for South (LHCC_S), East (LHCC_E) and West (LHCC_W) sectors as well as forBudapest TMA. The heaviest workload appeared in LHCC_S sector. A vertical split at FL 340was tested and the workload level for the two new sectors was drastically decreased althoughit remained severe for the lower sector (up to FL 340). With existing route structure this isconsequently recommended. LHBP TMA will require a split into two sectors during busyperiods. Re-sectorisation of Budapest FIR is already planned. Bratislava FIR LZBB FIR had moderate workload throughout even at 2003 level. • Future organisation D The shifting of traffic to new routes had a dramatic effect in the southern part of the simulationarea. Vienna FIR The traffic in Vienna South sectors was forecast 40-45% lower than the Corganisation due to preference to re-opened routes through former Yugoslavia. Other Viennasectors were only slightly affected by the route changes.

Budapest FIR Budapest South sector was forecast to have 45% less traffic than the Corganisation promises. If ARN V3 is fully implemented as foreseen in this study theaforementioned need for splitting the LHCC_S sector will not be necessary. Other sectors wereonly slightly affected by the route changes. Bratislava FIR The D organisation forecasted a traffic increase of approximately 10% throughthe new route structure. • Unfulfilled objectives:
One of the objectives determined during the first meeting was to optimise sectorisationirrespective of National boundaries.
In spite of some initial ideas, the project did not produce any such solutions. For flights fromLHCC FIR inbound to LOWW the routing is via a part of LZBB FIR that is delegated to LHCC.Other re-routings were tried which take flights from LHCC FIR into LZBB FIR en-route toLOWW, but no initiatives to sectorise across the FIR boundaries were taken.
Reaching agreements concerning airspace division APP/ACC within the National airspace wasdifficult, and the working group found no obvious advantages in sectorising across the FIRboundaries. Perhaps the only solution is to conduct a totally unprejudiced simulation andattempt to set sectorisation according to traffic flows alone. The ATC sectors in the boundaryarea between the states are already busy and, at least for the lower airspace, it is difficult tosee how a re-sectorisation would lead to fewer, more efficient sectors.
Regardless of sectorisation, the separation minima for border crossing between the threecountries were set to 10-15 NM, considerably more than the 3-5 NM required for separationwithin any National airspace. Co-ordinations tasks timing was also longer for inter-centre co-ordination, as more information was included in a pilots first call to a centre, than to a newsector of the same centre. Consequently the task timing was longer, and the workload for theassociated sectors was increased by the mere fact that they belong to different Centres.

1. DESCRIPTION OF THE STUDY
1.1 INTRODUCTION
A three state Real-time simulation planned for 1999 sponsored by EUROCONTROL DED/4led to the allocation of a fast-time simulation slot for September 1997. The First preparatorymeeting was held in Budapest on the 15th of April 1997. Following this meeting an analysisof the airspace was performed in Brussels from 24 June to 26 June 1997 using the SAAM(System for Analysis and Assignment at a Macroscopic level) tool. This analysis formed thebasis for the fast-time simulation project. The fast-time simulation was conducted using theEUROCONTROL Reorganised ATC Mathematical Simulator (RAMS). The purpose of theproject was to examine the interface between the terminal areas around Bratislava, Viennaand Budapest airports, to study the effects of the new route network (ARN V3), and tosimulate future traffic levels and optimise the sectorisation in the area. EEC Task No. F18was assigned to this project.
As basis for the study August 7 1997 was chosen as a reference date. The purpose of thereference organisation was to simulate the current traffic and operational conditions of thethree states in order to validate the performance of the RAMS model and to provide abaseline against which proposed changes and future traffic could be measured.
1.2 STUDY TIMETABLE
The Fast-time study at the EEC began in September 1997 with editing of traffic samples andairspace data input.Initial trends were anticipated early 1998. During the autumn a number of events led to adelay in getting the data right. One major setback was that the initial CFMU sample studiedhad to be abandoned in favour of merging the three national traffic samples.
A simulation study with RAMS can be done with or without conflict resolution. To chooseconflict resolution means allowing the simulator to find a resolution to a conflict and takingthe appropriate action, climb, descent, vectoring or whatever the rulebase deems necessary.After testing during the autumn of 1997 and finding that the rulebase decisions were notreliable and 25-30% of the conflicts were left unresolved, we, the working group decided torun the simulations with conflict detection only. By doing this we maintained control over theflights which would always follow their flightplans and penetrate the sectors foreseen. Allconflicts would lead to the same allocation of workload to the controller irrespective of thetype of conflict found.
In December all the data had been collected and the first results were produced early 1998.During a progress meeting in Brétigny March 2-6 further updates were made, includingsector changes for LOVV FIR. During March the first output files from the simulations weresent to the working group for verification and during the spring the remaining simulationswere run and analysed.
The final results were presented in Vienna, Budapest and Bratislava between 1st and 4th
September 1998.

1.3 OBJECTIVES OF THE STUDY
The three countries for the study identified four main common objectives:
● To analyse the current system including SIDs and STARs concerning the TMA interfacebetween Bratislava - Vienna - Budapest.
● To study the effects of the ARN V3 route network, re-sectorise and, as necessary, re-align or create new SID and STAR to join the new route system.
● To study the effects of future traffic increases.
● To harmonise routes and optimise sectorisation of TMA and ACC sectors irrespective ofNational boundaries.
A fifth objective was added during the course of the study:
● To simulate the whole area irrespective of levels in order to properly assess the effects of ARN V3 route network changes to the area. This served the purposes of the three participating countries as well as EUROCONTROL. 2. INPUT DATA To carry out a simulation study using RAMS numerous data items are required. ◆ Actual and future traffic samples◆ Airspace environment and sectorisation details.◆ Controller task specifications and positions simulated.◆ Separation standards.
2.1 TRAFFIC SAMPLES
2.1.1 1997 Traffic Sample (A and B organisations) It was agreed to use a 24-hour traffic sample for the 7th of August 1997. An initial attempt touse the CFMU sample was abandoned since it was found that 5-7% of the traffic did notcorrespond to the three national samples provided. Instead the national samples werecompiled and verified during meetings in Brétigny Sep 30-Oct 2 (Slovakia), and Oct 12-14(Hungary/Austria). The final traffic sample for 1997 contained 2928 flights. The workinggroup verified all routes flown by the traffic in the sample.
2.1.2 2003 Traffic Sample (C and D organisations) The 1997 sample was cloned in RAMS by 40% overall and contained 4100 flights. The cloning methodology ensures that existing flights are reproduced on the same routes atthe same levels with up to 180 minutes offset entry time into the simulation. This means thatroutes that were not flown on 7 August 1997 will not be flown in 2003, exception being Organisation D, where traffic was transferred to ARN 3, then cloned. Furthermore the 40%cloning was set so that all sectors in the study had a traffic increase of 38-42%.

2.1.3 Aircraft types found in the traffic samples
In the chart above, the blue bars represent the most frequently used aircraft types in thesample from 1997. The entries in red on the right show some of the most recent aircrafttypes. Note that their numbers are very low. For future simulations it must be expected thatthese will replace older aircraft types gradually. However, the TAS of the aircraft involveddoes not differ significantly, and it is uncertain which would appear on which route andtherefore, when the future traffic levels have been cloned, the old aircraft types have beenretained.
2.2 AIRSPACE SIMULATED
2.2.1 Flight information regions The airspace simulated consisted of VIENNA FIR (LOVV FIR), BRATISLAVA FIR (LZBBFIR) and BUDAPEST FIR (LHCC FIR), from ground to the top of controlled airspace. LOVV FIR was simulated excluding the airspace delegated to Rhein UAC, overlyingInnsbruck LAU (LOWI LAU). To Include Ljubljana FIR (LJLA FIR) in the simulation wasdiscussed but abandoned following a 1997 decision not to incorporate LJLA into LOVV asearlier discussed. The focus of the simulation was on the interface of the three countries inthe area Vienna - Bratislava - Budapest.

Arriving and departing flights were simulated to/from the main airports but workloads in theControl zones and the aerodrome control towers were not measured, since aerodromecontrol and runway occupancy were not an objective of simulation.
2.2.2 Sectorisation and Route description Details of the airspace, sectorisation and SIDs/STARs were supplied to the ExperimentalCentre. The data was continuously discussed, corrected and updated during our meetingsand were considered definite following the March 1998 meeting at the EEC. Organisation A used the sectorisation and routing existing in August 1997. For scenariosreferring to Organisation B and following, amended SID/STAR systems for LOWW, LZIB andLHBP were used. Commonly agreed new routing of traffic inbound to / outbound from LHBPand LOWW were also used. An extended LZIB TMA was simulated in Organisation B.
2.2.3 Sectors simulated and measured Vienna (LOVV) FIR Vienna (LOWW) TMA, which consists of a number of sub-sectors. For each exercise thesectorisation may differ. See the sector abbreviation list (page vi) for details of sectornames and abbreviations. En-route sectors East (LO_E), West (LO_W), South (LO_S), North (LO_N) and B5 LO_5).For each exercise it is indicated if sectors are combined, i.e. SE means a combined Southand East sector, mention of L, U and T as a suffix indicates a vertical split into Lower, Upperand Top sectors. Budapest (LHCC) FIR: Budapest (LHBP) TMA, En-route sectors South, West, North and East. Bratislava FIR Bratislava (LZIB) TMA, En-route sectors Low (LZ_1), Middle (LZ_2) and High (LZ_3)
2.2.4 Overview The following map outlines the airspace simulated and shows in yellow the routes flownwithin the three Flight Information Regions. All sectors and FIRs not mentioned above werenot measured for ATC workload. The three FIR’s simulated are shown in the centre of the following map, and the routesdepicted are taken from the REFE scenario. Note that only the en-route flight profiles appear on the map. The arrival and departureroutes do not appear. For reference some of the navigation aids used for en-route navigationin the area are included.

2.3 ATC Tasks and positions simulated ATC tasks were defined with conditions and time values as described in Appendix A. Each sector was manned by a Planning Controller (PC) and Tactical Controller (TC) withone exception; the Feeder sector in Vienna TMA where only the Tactical Controller wassimulated. Flight data tasks were defined and measured only where they were carried out byone of the sector controllers.

2.3.1 ATC Task description Task description was agreed within the working group during the December 1997 meeting. Additions, corrections and updates were applied during the March 1998 meeting. The tasks were described in two ways: 1) GENERAL, in which case they are generic for all centres or for a specific centre.
2) SPECIFIC, in which case they were recorded only under specific conditions set out in the task description for a certain group of flights.
2.3.2 ATC Task Groups
ATC Tasks were divided into five groups:
2.3.2.1 Flight Data Management Includes tasks for the PC and TC concerning loading and removing of flight progress strips.
2.3.2.2 Conflict Search For all sector entries, the conflict search task is performed by both PC and TC to assess thesituation and determine the need for further actions.
2.3.2.3 Co-ordination Consists of both internal and external co-ordinations (within and outside the own centre) andalso includes both standard co-ordinations and others depending on dynamic conditions.
2.3.2.4 R/T communication This group of tasks includes the standard R/T communication between controller and pilotconcerning sector entry, requests for climb/descent and hand-over to next sector.
2.3.2.5 Radar Activity This includes the task assigned to the Tactical controller when conflicts are found to modelthe resolution of the conflict. Specific radar tasks mainly concerning vectoring for the TMAsectors also belong in this group. For the complete list of ATC tasks, times allocated and description see appendix A.

3. ORGANISATIONS SIMULATED
3.1 Organisation A The principal reference organisation from August 7, 1997. Three separate exercises: • “REFE”(easterly runway config) A 24 hour exercise with the following runway configuration: LOWW 29-DEP/34-ARR, LZIB04-DEP/31-ARR and LHBP 31L-DEP/31R-ARR. In this exercise all sectors were open (fordescription see below), military sectors “TAW”, “TAE”, “ALL” and “ISH” were open in LOVVFIR generating additional workload due to co-ordinations, re-routings and additionalmonitoring. Extra co-ordinations with military authorities and adjacent sectors for all flightsleaving cruising level or deviating from flight plan were simulated for LZBB ACC sectors.Three open sportsfields within LHBP TMA generated extra workload due to extra monitoring,vectoring and altitude restrictions. The sectorisation for LOVV was: West sector divided into WL (125-285), WU (285-340) andWT (340-999). North sector divided similarly into NL, NU and NT sectors. The South andEast sectors were combined but split vertically into SEL, SEU and SET at FL 285/340.Sector B5 was not split and the LOWW TMA consisted of a TMA Low sector - TL up toFL105 and the upper sector split into a TUN (North) and TUS (south) with vertical limitsFL105-FL245. LZIB TMA had upper limit FL 105 and the three ACC sectors were LZ_1 (FL50-FL285except overlying LZIB TMA FL105-FL285), LZ_2 (FL285-FL340) and LZ_3 (FL340-FL999). LHCC FIR had all sectors (North, East, South and West) without vertical splits FL75-FL999.LHBP TMA had an upper limit FL195. • “REFW”(westerly runway config) A 24 hour exercise with the following runway configuration: LOWW 29-DEP/16-ARR, LZIB13-DEP/22-ARR and LHBP 13L-DEP/13R-ARR. In this exercise the LOVV North, Southeastand West sectors were split only at FL340, all other sectors were identical to REFE and nomilitary areas or sportsfields were active. • “REFX “An exercise with Easterly runway configuration without military or sportsfield activity. LOVVACC and TMA sectors were not split vertically, LZIB TMA was simulated with reduced upperlevel FL 85. For LHCC FIR this simulation gave a direct comparison of workload with andwithout the active sportsfields simulated in REFE.
An early request to simulate a laterally extended LHBP TMA was abandoned. An additionalrequest from Hungary was to study the effect of re-routing inbound traffic to LOWW viaDIMLO-BABIT into LOVV South sector. This sub-scenario was referred to as REFX-DIMLO.

3.2 Organisation B “B1” Also at 1997 traffic level including revised SID/STAR system, redesigned routes forinbound and outbound traffic (Fig 1), and extended LZIB TMA with upper limit FL195. Based on B1 additional exercises were also run for Vienna to evaluate different verticalsplits between TMA and en-route sectors. “B2” Different vertical sectorisation in Vienna FIR, alternative routing of flights and BratislavaTMA with upper limit FL85.
3.3 Organisation C Traffic was cloned from the B organisation by 40% and the route structure from OrganisationB was maintained. The new traffic levels corresponded to the EUROCONTROL forecast forthe year 2003 as published by DED/4 in June of 1997. “C1” Studied the effect of the additional traffic on the ATC workload. “C2” Tested different vertical sector splits. Vienna East sector tried a combined low andupper sector (LO_ELU), the vertical split of Budapest South sector at FL340 and BratislavaTMA with an upper limit of FL105.
3.4 Organisation D “D1” This was the 2003 traffic as simulated in the “C1” exercise transferred to ARN V3 routenetwork. In addition to the above a number of sub-exercises were run to study specific areas. Theseare explained in the section relating to simulation results.

The controller workload was divided into five different groups of tasks. The next chart showsthe percentage of working time spent on each task group over the 24 hours. Note that thischart does not show the workload or total time spent on each task, only the relationbetween the task groups. The red bars show the radar activity, which includes specifictasks for TMA traffic (vectoring, speed restriction and spacing of inbound traffic) and theresolution of conflicts in all sectors. The red bars and their relation to the other task typesgives an indication of the complexity and density of conflicts in the concerned sector.

Note that in the previous chart the difference between percentage-marked sectors indicatinghigh complexity in LOWW TMA and, the comparison with the low occurrence of conflicts inthe LO_5T sector. This chart shows the sector workload. Flight data and conflict searchtasks represent the combined working time for the Planning Controller and the TacticalController.
The following chart shows the peak workload for the tactical controller in the LOVV sectors.The busiest one hour and three hour periods are shown. The workload is shown as anaddition of all the tasks specified for each controller and continues to increase above 100%.Note that even in 1997 for the reference organisation, three sectors (highlighted in turquoise)have a workload above what is generally seen as the limit for severe workload, i.e. 50% overthree hours and 70% over one hour. The most overloaded sector is the Low TMA sector. Inthe case of the ACC sectors they are combined for this exercise and can be separated inperiods of high traffic. Because of this the overloading of the ACC sectors is not necessarilya problem. Note that number of flights and workload does not necessarily follow each other.The TMA sectors show much higher workload due to the labour-intensive handling ofarriving traffic in the TMA environment.

4.1.2 Budapest FIR Reference organisation:
The following bar-charts show the traffic entries per hour, percentage of each task groupper sector and the peak workload for the tactical controller over the busiest one andthree hour period in the REFE scenario.
The traffic in Budapest FIR, as seen above, shows the highest number of flight entries in theSouth sector, with East and West sectors not far behind.
On the next chart the percentage of working time spent on each task group over 24 hours isshown. Note that this chart does not show the workload or total time spent on eachtask, only the relation between the task groups. The red bars show the radar activity,which consists of specific tasks for the TMA traffic for vectoring, speed restriction andspacing of inbound traffic and the resolution of conflicts in all sectors. The red bar and itsrelation to the other task types gives an indication of the complexity and density of conflictsin the concerned sector.
For Budapest FIR this shows a higher level of complexity with more radar actions requiredper flight in the TMA sector, than in the en-route sectors.

The following chart shows the peak workload for the tactical controller in the Budapestsectors. Note that even in 1997 for the reference organisation, the South sector is severelyloaded by the standards normally used, i.e. 50% over three hours and 70% over one hour.The three hour load for Budapest TMA is also severe – 51%.
Comparing the traffic count per sector and the associated peak workload, we can note thatthe number of flights and workload do not necessarily increase with each other. The Southsector which had approximately 10% more traffic than the east and west sectors recorded apeak workload almost 50% higher than the other en-route sectors. This indicates a highercomplexity with more aircraft appearing in conflict with each other.

The TMA is also labour-intensive. Compare the peak workload between the North sectorand the LHBP TMA. With similar traffic count the workload is infinitely higher in the TMA.
4.1.3 Bratislava FIR Reference organisation:
The following barcharts show the traffic entries per hour, percentage of each task group persector and the peak workload for the tactical controller over the busiest one hour and threehour period in the REFE scenario.
In Bratislava FIR the traffic is well distributed between the en-route sectors with sector LZ_2counting 272 aircraft over 24 hours compared with 224 for LZ_3 and 186 for LZ_1. Note theclearly defined peaks that occur at different times in the three sectors. Low traffic inBratislava TMA.
The next chart shows the percentage of working time spent on each task group over the 24-hour period. Note that this chart does not show the workload or total time spent oneach task, only the relation between the task groups. The red bars show the radaractivity, which consists of specific tasks for the TMA traffic (vectoring, speed restriction andspacing of inbound traffic) and the resolution of conflicts in all sectors. The red bar and itsrelation to the other task types gives an indication of the complexity and density of conflictsin the concerned sector.
Note the difference between Bratislava TMA and the en-route sectors which have, bycomparison low occurrence of conflicts. This chart shows the sector workload and thereforecombines the tasks performed by planning controller and tactical controller.

On the next chart, the workload is compared sector by sector. Comparing with the trafficcount per sector we note that number of flights and workload are not necessarily completelyassociated with each other.
The low en-route sector LZ_1 has approximately 30% fewer flights than LZ_2 but still thepeak workload in LZ_1 exceeds that of LZ_2. The reason for this is that more conflictsoccur in the lower airspace, resulting in a higher workload. This is not surprising since moreaircraft are in climb/descent at lower levels.

4.1.4 Workload distribution – all sectors
The chart above shows that the TC (red bars) is the busiest controller in all sectors. It alsoshows the level of workload during the busiest three hours for each sector. This is notnecessarily the same time as previously shown in charts with traffic evolution. Some sectorswill be open only during peak hours - the workload of all sectors should therefore berepresented using a three-hour busy period as comparison. Overload at present traffic levelaffects the TC for LO_SEU, LO_TL, LHCC_S, LO_NU, LHBP_TMA and LO_SET over thethree busiest hours. The busiest level recorded for a PC was 40%. Since the TC figureswere more indicative of sector overload they were used for comparison except wheresignificant workload for the PC was noted.
4.1.5 Studies of extra work in the “REFE” scenario
The REFE scenario was specified for each ACC with extra tasks for military co-ordination inthe case of LOVV and LZBB, and for “open sportsfields” within Budapest TMA for LHCCFIR.
In the following charts the effects of military activity and sportsfields is shown centre bycentre. For LOVV and LHBP the extra tasks were shared between the TC and PC but inLZBB all the extra tasks were allocated to the PC.

The following chart looks at the effect on the Bratislava Planning Controllers of open militaryareas and the associated co-ordination tasks required and specified.
The difference in workload above is obvious, (25-30% increase in workload during thebusiest hour) but since the workload was not significant it was agreed not to run moresimulations to highlight this effect. With a continued increase of traffic and associatedworkload this may still be a future item of interest.

Although there was an effect on the total workload for the PCit did not manifest itself in the busiest hour but the TC was affected by a 10% increase of thepeakloading through extra level-restrictions on arriving flights and extra monitoring tasks forarrivals and departures. The effect of the open sportsfields, which is an important constrainton the TMA controllers, could probably be better assessed in the following real-timesimulation.

The military co-ordination was reflected through two different scenarios for LOVV FIR. Thefirst scenario delegated the following areas to the military:
Tauern West (TAW) FL125-FL245,Tauern East (TAE) FL125-FL245,Allentsteig (ALL) GND-FL460, andIschl (ISH) FL245-UNL.
The second scenario delegated:
Tauern West (TAW) as before but with re-delegated “Munich corridor FL155-FL245,Villach East/West (VIE/VIW) FL125-UNL,Lienz (LIE) FL125-UNL andTauern South (TAS) FL245-UNL
The extra work caused was measured by definition of extra co-ordination tasks between thesectors and the military, re-routing of flights and monitoring the compliance with instructions.The effect (mainly on the PC) is shown in the chart below.
The chart above shows the effect on PC workload of military co-ordination within LOVV FIR.The blue bars indicate no military activity. The red bars represent REFE (MIL scenario 1)while the yellow bars represent MIL scenario 2. The peak loads for the planning controllerswere not significantly affected. The most notable difference was in scenario 2 where thepeak hour workload increased from 14% to 20% for WT and from 23% to 27% for WU.

4.2 Organisation B.
The scenarios in Organisation B retained the 1997 traffic but simulated agreed newSID/STAR routes and tested suggested route changes for LOWW arrivals from LHCC FIR.The amendments were done in order to optimise the use of airspace regardless of theexisting FIR and sector boundaries, and were agreed during a meeting in Bratislava betweenthe national ATS specialists.
ARN V3 was simulated in a scenario at 2003 traffic levels and was based on the latestagreement reached in May 1998.
4.2.1 Exercise B1
Exercise B1 tested an increased LZIB TMA with upper limit FL195, LOWW TMA with threeTMA sectors plus a feeder in the lower sector concerned only with LOWW arrivals. TheLOVV ACC Sectors E, S, W, N and B5 were all simulated separately with level-splits at FL285 and FL 340.
Flights from LHCC FIR with destination LOWW previously on track JULIA-LOWW were re-routed JULIA-TPS-ERGOM (FL310-) -OKI-JAN-OKR-WGM.
Studies for Vienna FIR
A specific request from LOVV led to additional versions of B1. To highlight the effect of re-routing inbound traffic to LOWW via SBG-SNU an exercise was tested and is referred to asB1b. The chart below shows a comparison of the traffic/sector for each exercise.

The upper TMA sectors were not greatly affected by a change in upper level. Almost allaircraft in the area below FL 245 were found to be in climb/descent to/from LOWW andpenetrated the sector regardless of its upper limit. The East_Low sector was described in B1as FL245-FL285, which gave a low number of flights, compared with the “B1-165” exercisewhere the sector was FL165-FL285. In the “B1-195” exercise EL was FL195-FL285 and, inthe “B1-205” exercise FL205-FL245. In this exercise an extra sector “E_M” was tried fromFL245-FL285. This is identical to the E_L already simulated in B1. Workload changes for theTMA were minimal.
Exercise B1C split the lower TMA sector into two. With RWY29 departures the division gaveall departures except the southbound ones to the TLN sector, and only arrivals that werealready in the level-band below FL105 and coming from the north, entered the TLN sector.
TLS was considerably busier but the peak three-hour workload for the TC was a modest41% compared to 73% for the combined sector. This is something to consider for the future.For comparison see charts below:

4.3. Comparison of all 1997 scenarios. (Organisations A and B)
The chart above shows a comparison of the workload over the busiest three hour period inthe five exercises at 1997 traffic level. The REFX figures may appear misleading since theupper level was FL245 instead of FL105 in the others. REFW in comparison with REFEshowed the difference between landing RWY34 (REFE) or RWY16 (REFW). It also showedthat the peak workload was reduced by up to 12% by using RWY16 for landing instead ofRWY34.
Exercise B1 and exercise B2 had new SID/STAR systems and re-routed inbound Viennatraffic from LHCC FIR via LZIB TMA. The new SID/STAR systems had already beenimplemented and found efficient. This was confirmed by the fast-time simulations and shownin the chart above. Compare REFE with B1/B2 where the peak workload was reduced byapproximately 7% through the transfer to new SID/STAR.
The REFX results show the effect of working the TMA as one sector at all hours, leading tosevere overload on the controllers.

The REFE scenario had the higher workload due to the “open sportsfields” in the TMA.(peak workload 59% compared to 55% in REFX). There was little difference in peak loadbetween the other scenarios.

Exercise B2 maintained the extended horizontal limits of the TMA but had a verticallimitation of FL85.
In REFE, REFW and REFX Vienna inbound traffic from Budapest FIR avoided BratislavaFIR. The routing is shown below, routes via BKS, TPS, GYR, KELAN into LOWW TMApenetrated LHCC_E and LHCC_W sectors before LOVV FIR.
In exercise B1 the route after TPS was ERGOM (310-)-OKI-OKR-WGM thus leavingLHCC_E into LZBB FIR before LOWW TMA.
In exercise B2 the route was further east, entering LHCC_N sector via BEVAR andcontinuing via LITKU into LZBB FIR, routing via SLC, NIT, OKR and WGM.
Only 11 flights appeared in the original sample and the effect was therefore minimal in thefast time simulation. Clearly the route transfer will relieve the LHCC_E sector and furthertesting may be done with more traffic in the real-time simulation.

4.4 Organisation C.
Exercise C1 used the traffic in the B1 exercise cloned to a forecast 2003 level (+40%). Anadditional exercise tested a vertical split at FL 340 of the LHCC_S sector and an upper limitof FL105 for LZIB_TMA.
Although all sectors had the traffic increased by 38-42% the peak workload effect variesfrom 31% to 61% in LOVV en-route sectors. The difference is due to the random cloningwhere it cannot be predicted which flight through a sector is cloned and which is not. Theworkload for each aircraft differs due to co-ordination tasks, conflict with other aircraft andtime spent in the sector. The unexpectedly low workload increases in sectors SL and WLUwhere the increase is only 33 and 31% respectively are due to this effect of cloning.
In the LOWW TMA Sectors below, workload increases by 40-53%

For LZBB FIR Exercise C1 tested upper limit of FL195. Exercise C2 tested the present upperlevel FL105 instead. Distribution of workload between TMA and lower en-route sector LZ_1for the two exercises is shown below. (Figures for 2003).

4.5 Organisation D. (ARN V3)
The ARN V3 route structure for future simulations as supplied by DED/4 in May of 1998 wasimplemented in exercise D1. To simulate ARN V3 the working group made the assumptionthat all countries would be able to offer the most direct routes available and that all operatorswould select the most direct routing.
Based on the automatic assignment to most direct route available through the SAAM tooldeveloped by DED/4 the traffic was re-assigned for each city pair to the preferred route. Thismade a great deal of difference especially where flights to/from Greece and Turkey wouldavoid LHCC airspace by routing via former Yugoslavia.
It should be noted that the ARN V3 organisation assumed full implementation of ARN V3route network, and also unlimited capacity for the routes shown. Any capacity problemsalong selected routes could bring some traffic back to the old routes as alternatives to themost direct.
However, the charging of en-route fees for the actual route flown instead of the earliersystem of most common route flown for each city pair is expected to lead to an evenstronger determination from airlines to request the most direct route available. This will putpressure on the system to avoid detours. With implementation of Reduced VerticalSeparation Minima (RVSM) between FL290-410, the capacity for en-route sectors will alsoincrease greatly.
The most affected sectors in the simulation were the south sectors in Hungary and Austriawhere, following the route transfer, the number of flights per sector was more than 40%lower than before, and in fact even lower than in 1997.
The eventual effect of ARN V3 is difficult to envisage, especially since new agreementsreached after the study was completed have further modified some routings. However the Cand D organisations gave us the forecast traffic level for 2003 and the agreed route networkwas reflected in organisation D. Changes to agreements or difficulties in fulfillingcommitments to routes agreed would lead to a return, in principle to organisation C. In thefollowing charts the expected traffic per sector is described in organisation B (1997 traffic onmodified routes), organisation C (2003 traffic level) and finally organisation D where thetraffic was transferred to ARN V3 route network.

Note above how, in 2003 the South sector with full ARN V3 implementation would havefewer flights than in 1997.
In LZBB/LHCC FIR above the most dramatic effect of ARN V3 would be 20% fewer flights in2003 than in 1997 in the LHCC South sector despite the 40% cloning of existing traffic.

The workload increase already presented for organisation C assumed the present routenetwork. The following charts also show the forecast peak workload with a transfer to theARN V3 route network. This assumed unlimited capacity on the proposed routes, nodeviations for any reason and no change to the route system, as presented in May 1998.The two possible levels for 2003 could be seen as a frame, indicating within whichlimitations traffic will be routed in the year 2003.
For LOVV en-route sectors note how the 2003 traffic in Organisation D gives a lower peakworkload than in 1997 for the south sectors. This is due to traffic bypassing the simulationarea to the South or in some cases finding new routings further East. Severe workload isindicated in the NU sector in both organisation C and D while the WL sector (FL340 andbelow) indicates severe workload in Organisation D.

For LHCC sectors ARN V3 indicates a dramatic drop for the South sector while the othersremain largely unaffected.
Vertical sector splits are practical solutions to overload of an en-route sector. In case thetraffic pattern is maintained as in Organisation C, a split in the LHCC_S sector at FL 340would be necessary and lead to the distribution of traffic and workload as shown above.

LZBB FIR is largely unaffected by the ARN V3 route network. A reduction of workload in theTMA appears strange at first, but is caused by aircraft descending into LOWW TMA thathave been re-routed in the new route network to avoid Bratislava TMA.

5. CONCLUSIONS AND RECOMMENDATIONS.
The simulation project looked at a number of different areas. The TMA traffic within andbetween the three TMAs was studied with different runway configurations, differentSID/STAR systems, different route systems and two different traffic levels. What can beseen from the first studies is that the REFW exercise appears to require less work andcauses less conflicts than the REFE / REFX /B1 exercises. The B1 exercise which used thenew proposed SID/STAR systems as well as new links between SID/STAR and ATS routeshas already been tried, both in simulation and reality and found to be effective. Therefore,the future organisations build on this exercise (B1), and not the Reference Organisation A.
5.1 Proposed Organisation.
As yet, the real-time simulation working group has not agreed on which route structure tosimulate. The ARN V3 route network will undoubtedly be implemented, but if this takes placeas in Organisation D or whether further changes are made remains to be seen. For manysectors both the existing and the new route system give similar forecast figures for trafficand workload. This should mean a greater degree of accuracy than extremes like LHCCSouth sector which indicated possible peak workload between 45% and 83%.
For LOVV sectors a combined SE sector will clearly be overloaded in the future samples, aswill the lower TMA sector. Separation of the South and East sectors is thereforerecommended. For LOVV TMA the heaviest workload is generated by the arrivals and aclear distinction between arrival sectors and a departure sector could be the best way ofdividing the workload evenly. See the B1C scenario.
Another LOWW problem is the number of flights and the runway capacity. If one runway is toserve as the normal arrival or departure runway it is difficult, if not impossible, to exceed 35movements/hour as a maximum. The future sample shows several hours where the numberof arrivals or departures reaches or exceeds that number. See chart on next page.
For LZBB FIR no overloading of sectors is forecast. The B1 scenario gives the bestdistribution of workload between the sectors since the extended LZIB TMA to FL 195becomes more of a low ACC Sector and is responsible for the co-ordinations with LOVV forin- and outbound traffic LOWW, relieving the LZ_1 sector.

5.2 Capacity issues
The most crucial problem in the area is for LOWW arrivals and departures. During the peakhour the evolution of traffic is a measure of whether capacity can be a problem. For LOWWTMA the number of arrivals per hour with only one runway for landing cannot exceed 35 asan absolute maximum. In the 2003 scenario this figure is reached between 0700-0800 andexceeded (38 arrivals) between 1000-1100. Between 0800-0900 and 1500-1600respectively there were 35 departures recorded. The lower TMA sector for LOWW should besplit into separate departure and arrival sectors when the traffic increase requires it. In the2003 exercises, the lower TMA sector is predicted to have as many as 59 flights/hour. Thisbreakdown in departures and arrivals per hour is shown in the following bar chart.
As shown above, the theoretical maximum runway capacity for departures were reached
with 2003 traffic in Organisation C and Organisation D. Moreover, runway capacities wereexceeded for arrivals in both organisations. A flexible use of runways for arrivals anddepartures will be necessary to avoid lengthy delays.
For the en-route sectors no capacity study was made but based on the simulation resultsthey do not appear to be a problem, even with the 40% extra traffic, except in LO_NU sectorwhich had an evolution of up to 50 flights/ hour.
For LHCC FIR the potentially busiest sector was the LHCC_S sector, but with ARN V3implementation it will be greatly relieved. If this should not take place a vertical split isrecommended at FL 340 to align with the adjoining LOVV sectors. Final agreement on ARNV3 was not completed before the last simulation exercises were run; therefore the effects ofagreements after May 1998 should be studied for further help.
