ABSTRACT
Identification of airport and airspace capacity constraints is complicated
by the presence of Air Traffic Flow Management programs that protect
congested airspace from becoming a safety problem. There are two ways
to proceed: one may use a simulation to reproduce the operational environment
without the ATFM, or one may analytically deduce the presence of the
capacity constraint from the evaluation of performance metrics based
on operational data. This paper describes a method by which the latter
has been accomplished, using multi-dimensional user-oriented performance
metrics to guide airspace redesign efforts in the eastern United States.
Throughput, delay, predictability, and flexibility metrics contribute
to the analysis. The analytical method is shown to have advantages in
resources required and geographical scope. The broader scope can also
be used to guide the choice of simulation parameters, when the greater
precision of simulation is required in the later stages of an airspace
or airport redesign.
