The Next Generation Air Traffic System (NextGen) offers a historical opportunity
to re-examine the assumptions and constraints in the current Air Traffic Control (ATC)
system and their effects on
ight efficiency and safety. Modern day commercial air-
craft are fully capable of
ying continuously varying smooth trajectories. However in
the current air traffic control ATC system, commercial
ight trajectories consist of a
series of segments due to historical development of navigation and surveillance systems.
Segments are defined by one or more constant parameters such as Mach number or
altitude. In this paper, characteristics and efficiencies of optimal free
ights when ATC
constraints are absent and optimal segmented
ights in the current ATC system are
compared. In this paper, aircraft
ights are modeled as a point-mass. Both horizontal
ight profiles are considered. Results of this paper seek to determine the
potential benefit of supporting continuous trajectories in future ATC systems.
