Airborne execution of flow strategies (AEFS) simulation

• AAR is one of the most significant variables that influence delays (as expected) + Effect on delays is much higher for AAR 80–100, than AAR 100–130 + Ground sequencing delays are much more sensitive to AAR than airborne metering delays • Lead Time of Planned Departure Time (LTPDT) could significantly reduce ID ground sequencing delays + With normal freeze horizon LTPDT effect on delays is much higher for LTPDT 0–30 min than 35–60 min + With extended freeze horizon LTPDT effect is consistent between the range of 0–60 min • Assigning High Priorities to ID significantly reduces their ground delays, but does not significantly increase average airborne metering delays • AEFS successfully redistributes metering delays from high priority to low priority flights without affecting non-fleet aircraft • AEFS does not require significantly more ATC actions • Maximum AEFS Imposed Delay Time (MDT) constraints do not typically affect delays • First-come, first-serve rule for ID could decrease their delays without significantly increasing average metering delays for airborne flights
