Concept Model



3 - DefinitionsTerm Definition

Duty. Any task that cabin crew members are required by the operator to perform, including, e.g., flight duty, administrative work, training, positioning and standby when it is likely to induce fatigue.

Duty period. A period which starts when a cabin crew member is required by an operator to report for, or to commence a duty and ends when that person is free from all duties.

Fatigue.

A physiological state of reduced mental or physical performance capability resulting from sleep loss or extended wakefulness, circadian phase, or workload (mental and/or physical activity) that can impair a crew member’s alertness and ability to safely operate an aircraft or perform safety related duties.

Flight Duty Period. (FDP)

A period which commences when a cabin crew member is required to report for duty that includes a flight or a series of flights and which finishes when aeroplane finally comes to a rest and the engines are shut down at the end of the last flight on which he/she is a crew member.

Flight time.

The total time from the moment an aeroplane first moves for the purpose of taking off until the moment it finally comes to rest at the end of the flight.Note: “Flight time” as here defined is synonymous with the term “block to block” time or “chock to chock” time in general usage which is measured from the time an aeroplane first moves for the purpose of taking off until it finally stops at the end of the flight.

Home base. The location nominated by the operator to the crew member from where the crew member normally starts and ends a flight duty or a series of flight duty periods.

Local night. A period from 0200 to 0600 local time.Non operating crew

memberAny country whose standard time falls within a band of 3 hours (+1:30 hours on either side of India) i.e. countries covered in the standard time zone band of UTC+4 to UTC+7.



Positioning. The transferring of a non-operating crew member from place to place at the behest of the operator.

Reporting time. The time at which cabin crew member is required by an operator to report for duty.Note: For the purpose of reporting time, the operator shall maintain a record.

Rest Period. An uninterrupted and defined period of time during which a crew member is free from all duties.

Split Duty (Break) A period free of all duties, which counts as duty, being less than a rest period.

Standby. It is a defined period of time during which a cabin crew member is required by the operator to be available to receive an assignment for a specific duty without an intervening rest period.

Ultra Long Range (ULR) Operations.

Continuous non-stop flights between the specific city pairs having a flight time of over 16 hours and duty periods upto 22 hrs.

Unforeseen operational

circumstance.

An unplanned event, such as unforeseen weather, equipment malfunction, diversions due to medical reasons or air traffic delay that is beyond the control of the operator.



Window of Circadian Low (WOCL)

WOCL is best estimated by the hours between 0200 and 0600 for individuals adapted to a usual day-wake/ night sleep schedule. This estimate of the window is calculated from scientific data on the circadian low of performance, alertness, subject report (i.e., peak fatigue) and body temperature.(i) For flight duty periods that cross 3 or fewer time zones, the window of circadian low is estimated to be 0200 to 0600 home-base/ domicile time.(ii) For flight duty periods beyond 3 or more time zones, the window of circadian low is estimated to be 0200 to 0600 home-base/ domicile time for the first 48 hours only.(iii) For a crew member remaining more than 48 hours away from home-base/domicile time, the window of circadian low is estimated to be 0200 to 0600 referred to local time at the point of departure.


Additional DefinitionsTerm DefinitionCalendar Day: means a 24-hour period from 0000 through 2359 using base time

Daylight Time:(Daylight Saving Time)(Summer Time)(DST)

Daylight saving time (DST) or summer time is the practice of advancing clocks during the lighter months so that evenings have more apparent daylight and mornings have less. Typically clocks are adjusted forward one hour near the start of spring and are adjusted backward in the autumn.

FRMS:

A data-driven means of continuously monitoring and managing fatigue-related safety risks, based upon scientific principles and knowledge as well as operational experience that aims to ensure relevant personnel are performing at adequate levels of alertness.

FRMS Policy:

A required component of an FRMS. THE FRMS Policy must: identify the elements of the FRMS and its scope; reflect the shared responsibility of all stakeholders in the FRMS; state the safety objectives of the FRMS; be signed by the accountable executive of the organisation; be communicated throughout the organisation; declares management commitment to effective safety reporting, to providing adequate resourcing for the FRMS, and to continuous improvement of the FRMS; identify clear lines of accountability for the functioning of the FRMS; and require periodic reviews of the FRMS.


Additional DefinitionsTerm Definition

Rest facility: means a bunk, seat, room, or other accommodation that provides a crewmember with a sleep opportunity onboard the aircraft.

:Class 1 rest facility

means a bunk or other surface that allows for a flat sleeping position and is located separate from both the flight deck and passenger cabin in an area that is temperature-controlled, allows the crewmember to control light, and provides isolation from noise and disturbance.

:Class 2 rest facility

means a seat in an aircraft cabin that allows for a flat or near flat sleeping position; is separated from passengers by a minimum of a curtain to provide darkness and some sound mitigation; and is reasonably free from disturbance by passengers or crewmembers.

:Class 3 rest facility means a seat in an aircraft cabin or flight deck that reclines at least 40 degrees and provides leg and foot support.

Standard Time(STD)

the official local time of a region or country determined by the distance from Greenwich of a line of longitude passing through the area

Suitable Accommodation:

means a well furnished bedroom which is subject to minimum noise, is well ventilated, and has the facility to control the levels of light and temperature.

Travelling: means time spent by a crew member transiting between the place of rest, and the place of reporting for duty.

AcclimatisationThe DGCA has decided to use a simple approach for dealing with Acclimatisation and Adaptation.

A system of 2 Zones of operation based upon Time Zone differences.• Zone 1

• Crew Member remains acclimated during the entire period within this zone.• The zone is from UTC + 3 to UTC + 8.

• Zone 2• International Operations(UTC + 9 to UTC + 12) and (UTC –12 to UTC + 2)• Crew Member remains acclimated to the time zone last acclimated to for the first 48 hours,

and is deemed acclimated to the new time zone after 48 hours has elapsed.


Acclimatisation

BOM

CDG


Adaptation• The CM will remain acclimatised to the Time Zone where last acclimated to for the first 48 hours.

• References to WOCL and Local Nights Rest remain fixed to the time zone where last acclimated to.

• After 48 hours away from the Time Zone where previously acclimated to, the CM will be deemed at the first FDP start after 48 hours, to be acclimated to the new time zone.

• Upon Return to Base, the CM must undergo another Adaptation Period. This is based upon the maximum Time Zone Difference during the Trip and Home Base. The Adaptation period is 36:00 rest including 2 Local Nights Rest for travel to Time Zones from in the range of (UTC+2 to UTC -2) or (UTC+9 to UTC + 12), and 72:00 rest including 3 Local Nights Rest for travel to Time Zones from in the range of (UTC-3.5 to UTC -12).

Time Zone Difference Rest period

> 3 and <= 7 36:00 with 2 Local Nights Rest

> 7 72:00 with 3 Local Nights Rest


Window of Circadian Low (WOCL):

Window of circadian low means the period between 02:00 and 06:00 hours in the time zone to which a crew member is acclimatised.


Flight Duty Period (FDP)

For a CM assigned to a duty period that contains Flight Time:• The start of the FDP is at report time (UTC) of a duty period.• The end of the FDP is at the arrival time (UTC) of the last working sector + minimum of

15 minutes for post flight duties.• Ferry flights are considered working flights when a cabin crew member is actually

working.

Rest Periods and BreaksLocal Night Rest

(LNR)means a period of 9 consecutive hours which includes the hours between 0200 and 0600 local time.

Weekly Rest Period (WRP)

means a time free of all duties consisting of a 24:00 continuous period including 1 local night’s rest

Bi-Weekly Rest Period (BWRP)

means a time free of all duties consisting of a 36:00 continuous period including 2 local night’s rest

Calendar day 24 hours period commencing at 0000 hr. local time.

The minimum time for a LNR is 9:00. • It may begin no later than 02:00, and end no earlier than 06:00.

o eg) A rest period that begins at 20:45 and requires a LNR has a minimum duration of 9:15, it may end no earlier than 06:00.



o eg) A rest period that begins at 06:15 and requires a LNR has a minimum duration of 23:45, it may end no earlier than 06:00..


Rest Periods and BreaksThe minimum time for a WRP is 36:00. It must include 1 LNR.

o eg) A rest period that begins at 01:45 and requires a 1 LNR has a minimum duration of 36:00, it may end no earlier than 13:45.



The minimum time for a FRP is 48:00. It must include 2 LNR.
