ABSTRACT
This paper describes the functionality of the Departure Enhanced Planning And Runway/Taxiway-Assignment System (DEPARTS), and how this functionality could potentially help reduce taxi-out times at Hartsfield Atlanta International Airport (ATL). DEPARTS generates optimized recommendations on runway assignment, departure sequencing and departure fix loading for the air traffic control tower to reduce taxi-out times. DEPARTS has initially been developed as a concept exploration laboratory prototype for ATL.
This paper analyzes the effect of improved predictability of ready-to- push-back times and of the availability of real-time surface event data (i.e., actual push-back and taxi clearance times) on the potential operational benefit of predeparture planning. Interim results are given, which will be completed after additional simulation experiments are performed. Operational issues in the improvement of readyto-push-back time predictability are outlined.
