Abstract
This paper presents a method to introduce linear
holding to flights affected by Airspace Flow Program (AFP)
initiatives. Trajectories are optimized at their planning stage in
such a way that the program performance is improved in terms of
delay absorption before the congested area, and delay recovery
at the destination airport. This recovery process is studied by
comparing the case where the same fuel consumption is fixed
as the nominal flight, with several cases where some extra fuel
allowances are considered at the flight planning stage. The effects
for AFP delayed flights are thoroughly discussed in a case study
followed by a sensitivity analysis on possible influential factors.
Results suggest that using the proposed method could partially
recover part of the AFP delay, even with no extra fuel allowances
(e.g., reducing 3.3 min of ground delay and 1.7 min of arrival
delay for a typical short-haul flight). When extra fuel is allowed,
however, the maximum delay recovery increases up to 10 min
for the studied case, which also proves to be more cost-efficient
than current operations, when flight speed is increased after
experiencing all delay on ground
