Operator DIAL on Friday announced the launch of the Delhi Airport-Collaborative Decision Making (DA-CDM) system. The system,being touted as a game changer for the Indian aviation industry,is expected to save 2,500 tonnes of Aviation Turbine Fuel (ATF) at Delhi’s Indira Gandhi International Airport.

A joint initiative of the Air Traffic Control (ATC),the GMR Group-led private operator DIAL and the airlines operating from the airport,the concept of DA-CDM focusses on improving flow of air traffic and capacity management at airports by reducing delays,improving predictability of events and optimising the utilisation of resources.

“The system involves airport operators,airlines,ground handlers and ATC collaborating and sharing data with all stakeholders. The project aims to improve the overall efficiency of operations at the airport,with a particular focus on the aircraft turn-round and pre-departure sequencing process,” an airport spokesperson said.

In the DA-CDM approach,milestones for the incoming aircraft,the turn-around time and the departure of the flight are defined to make the operation precise and predictable.

“The move will allow us to save 7,850 tonnes of CO2 emission by reducing the taxiway time by even a mere one minute per aircraft. With three operating runways and the upcoming state-of-the-art ATC tower,we are poised to handle a robust air traffic with best accuracy and efficiency,” CEO of DIAL,I Prabhakara Rao,said.

Two of the most important milestones in the new approach are the target off block time (TOBT) — fixed by the airline or the ground handler s between 45 and 20 minutes before the estimated departure — and the target start-up approval time.

“After two years of diligent work,Delhi ATC has managed to achieve this with DIAL’s support. The system will enable optimum utilisation of ATC resources and runways/taxiways,resulting in reduced workload of controllers,minimum ground delays and increased safety,”

P K Mishra,executive director (air traffic management),said.
