Airport Collaborative Decision Making

“Airport Collaborative Decision Making is the concept and a tool which aims at improving Air Traffic Flow

and Capacity Management (ATFCM) at airports by reducing delays, improving the predictability of aircraft

events, planning and optimizing the utilization of infrastructures and natural resources“

Air Traffic Movement in Delhi Airport is 1100 Per Day

24

Problem Statement

Failure of Airlines aircraft scheduling & planning due to limited information

Customer dissatisfaction due to aircraft delays, imprecise aircraft arrival and departure information

Underutilization of resources and Airport infrastructure

High use of ground vehicles operations

Huge fuel consumption, greenhouse gas emission, noise issues etc.

How do we

reduce costs,

lower

emissions,

improve

punctuality,

an d forge

stronger

partnerships?

25

Problem Identification & Root Cause Analysis

Why • Delay in landing and take off of Aircraft.

Why • Improper resource utilization due to communication errors between ATC and airport

Why • Inefficient use of Departure sequencing based upon “first call first served” between ATC and Airlines.

Why • Lack of Proper Synchronization.

Before After

� Aircraft Operator does not have clear

awareness about the Status and location of the

Aircraft.

� Ground Hander Operator do not have exact

information of the arrival time due to which there

is lack in resource usage.

� Fuel burn due to queues at the threshold is high.

� ATC operator don't have traffic information for

improved runway and capacity planning.

� Customer Satisfaction index is also very low due

to the delay in flight operation

� PFD (process flow diagram) from landing to Take

off is simplified.

� Pre departure Sequence Dashboard to provide

complete information in a bird's eye to AOCC

(Airport Operations Control Centre), ATC(Air

Traffic Controller).

� Due to CDM the Synchronization of Complete

system streamlined

� Customer satisfaction index also Increased.

Before and After Scenario Comparison

31

Benefits of A-CDM

� Airport Operator has been able to ensure optimum utilization of airport infrastructures, leading to

improved OTP over the years and increase in ATM capacity. More stable traffic flows and reduced taxi

times have led to fewer queues at the runway or congestion on the apron or taxiways.

� Air Traffic Control has benefit from improved runway and capacity planning. More accurate take off time

predictions has led to more accurate calculations of the network demand by the Network Operations.

� The Ground Handler has benefited from more accurate arrival times, which allowed for more accurate

planning with more efficient use of resources.

� Aircraft Operators have an improved awareness about the status and location of the aircraft. Together

with sequence information and better arrival times, more accurate fleet predictions have resulted in

overall efficiency improvement. Fuel burn due to queues at the threshold will be reduced, which has both

economic and environmental benefits.

� Passengers will benefit from reduction in delays, and fewer missed connections. After disruptions

recovery will be faster. Also for arrivals more accurate information can be delivered to FIDS and service

desks.

Benefits of A-CDM

Current OTP of Delhi Airport is 88% (April, 2016)Highest OTP achieved for departure is 93% (September, 2015)

Highest overall OTP achieved is 90% (September, 2015)

33

↗ First Airport in the country to have achieved this. It involves airport operators, airlines, ground

handlers & ATC collaborating and sharing data to increase overall airport efficiency. (5th June, 2013)

↗ The concept focuses on improving air traffic flow & capacity management at airports by reducing delays,

improving the predictability of events & optimizing the utilization of resources.

↗ 1 Minute reduced taxi time per Aircraft leads to saving of 2500 tons ATF = 7850 tons CO2 emissions per

annum.
