Flight summaries contain flight tracks for the following aircraft: both NOAA WP-3D's, NCAR Electra (L-188), NASA DC-8 and ER-2, C-130, and Cessna.
Aircraft tracks are nominally 45 minutes long and color coded by aircraft as indicated in the right side of the image. Small circles are at 10 minute intervals along the track. Note that the small aircraft is at the end of the track, corresponding to the location of the aircraft at the time indicated on the top left of the image. The aircraft icon itself always points north, independent of the direction of aircraft motion.
