This paper introduces a strategy to include linear
holding into air traffic flow management (ATFM) initiatives,
together with the commonly used ground holding and airborne
holding measures. In this way, ATFM performance can be
improved when handling delay assignment with uncertainty.
Firstly, a trajectory generation method is presented, aiming at
computing, per flight, the maximum linear holding realizable
using the same fuel as the original nominal flight. This
information is assumed to be computed and shared by the
different airlines and it is then used to build a network
ATFM model to optimally assign ATFM delays, in the scope
of trajectory based operations. Hence, the best distribution
of delay is optimized at given positions along the flight
trajectory (combining the three holding practices together) and
taking into account the cost of delay, especially in the fuel
consumption. The problem is formulated as a mixed integer
linear programming and solved with a commercially-of-the-shelf
solver. An illustrative example is given, showing that under the
circumstance of capacity recovered ahead of schedule, including
linear holding contributes to a notable delay reduction compared
to the case where only ground and/or airborne holding apply.Peer ReviewedPostprint (published version)
