The focus of the Airport Collaborative Decision Making (A-CDM) concept is to establish procedures and systems to co-ordinate sharing and usage of operational data amongst airport partners [including airport operators, airlines, ground handlers and air traffic control (ATC)]. Through information sharing, A-CDM aims to enhance situational awareness and aid in decision-making processes by airport workers – leading to improved operational efficiency and optimised use of resources.
For example, based on an accurate prediction of the aircraft’s readiness for departure (through information provided by ground handlers and airlines), ATC can plan an optimal pre-departure sequence at which aircraft are dispatched from the parking stands, thus reducing time spent by the aircraft idling before take-off.
