The Teledyne AirFASE software evaluates
LONG FLARE:
as time from 30 ft RA to touchdown with limits of 10, 12, and 14 seconds.
LONG TOUCHDOWN (ILS approaches only):
monitored distance from THR (Runway Threshold, position on the ground where ILS glideslope crosses 50ft above ground level). Input parameter is G/S deviation, RA, and distance measured by integrating longitudal acc to speed and then distance. Factory limits are 750 / 900 / 1050 m.
