Minister of State for Civil Aviation, Shri K. C. Venugopal informed the Lok Sabha today that Indira Gandhi International Airport (IGIA), Delhi has recently introduced an advance system called Airport Collaborative Decision Making (A-CDM) to curb delays in landing and take-offs and make them precise and predictable.

 Airport Collaborative Decision Making works on target timings rather than the estimates. It is a major shift in the working of airport operations from the conventional system. A-CDM facilitates the sharing of operational data for a better informed, well-planned and transparent decision-making to ensure more precise overall operational processes. It leads to an optimised utilisation of resources, an efficient turn-around process and everyone has common awareness of the situation.  A-CDM effectively enhances predictability, overall efficiency and punctuality by linking and sharing of accurate and timely information among airlines, airport operator, Air Traffic Control, ground handlers etc. All the partners work in close collaboration.   The overall improvement, in landing and take-off time of planes, is as follows:

On Time Performance     Before A-CDM    After A-CDM

Departure                          79.4%               86.4%;

Arrival                               73.0%               79.2%;

At present, more than 30 countries are using A-CDM including Germany, France, United Kingdom, Switzerland, Belgium and  Australia.
