Supplemental Plots on Trajectory Specification
This webpage provides supplemental plots for the following papers on
Trajectory Specification by Russ Paielli and Heinz Erzberger from the
Aviation Systems Division at NASA Ames Research Center:
The length of journal papers is limited, and only a few plots can be
included. However, many interesting plots were generated for visualizing
aircraft trajectories, air traffic, and the conflicts to be resolved in
the simulation. A sampling is provided below in the form of PDF
files. These plots are useful for documentation, engineering analysis,
algorithm development, and software testing.
The best way to view these plots is with your PDF viewer in a mode in
which you can use the right-arrow, down-arrow, or page-down key to
advance one full page at a time (rather than scrolling). Depending on
the PDF viewer that you are using, that may require downloading the file
and/or selecting a viewing mode such as "full screen" or "fit to
screen".
Airspace Route and Traffic Plots
Arrival Spacing Maneuvers
Conflict Resolution Maneuver Candidates
Pairwise Conflict Resolution
Simulated Traffic Motion
The following plots show the planview geometry of air traffic
encounters at constant velocity (i.e., constant speed and
direction). These trajectories are based on idealized velocity vectors
with no tolerances and are therefore not representative of trajectory
specification, but they are useful for illustrating the basic geometry
of air traffic encounters.
Constant-Velocity Encounters
All plots shown in the links above were generated with my open-source
software package called "Physical Scalars and Plotting Tools in Scala," which provides a
Scala API for the free GRACE plotting package.
