EXCESSIVE RATE OF DESCENT ALERTING AND
WARNING
The KGP 560/860 GA-EGPWS uses both GPS Vertical Velocity and
pressure altitude to compute vertical velocity information when the air-
craft does not provide specific air data for this purpose. In either case,
when the aircraft is descending toward terrain at a high rate for its rela-
tive altitude above terrain, the system will provide alerting and warning to
the pilot. This function is always active.
