Inadvertent Descent / Loss Of Altitude After Take-Off - Honeywell Bendix/King KGP 560 Pilot's Manual

Functions and Features
INADVERTENT DESCENT / LOSS OF ALTITUDE AFTER
TAKE-OFF
The KGP 560/860 GA-EGPWS uses known runway position and eleva-
tion information to monitor altitude during take-off and initial climb. This
function is active until the aircraft reaches an altitude of approximately
700 feet above the runway elevation used for take-off.
Should the aircraft experience an inadvertent descent or loss of altitude
after take-off, the system will illuminate the yellow caution annunciator
lamp and provide "Don't Sink-Don't Sink" voice alerts to the pilot. The
voice alerts will be repeated with increasing frequency.
The following graph shows this alerting envelope:
Descent After Takeoff
As the pilot adjusts the flight path of the aircraft and a positive rate of
climb is re-established, the voice alert "Don't Sink" will cease and the
yellow caution annunciator lamp will extinguish.
NOTE: It is important for the pilot not to over-react to this situation. While
it is important to react quickly and positively to re-establish a positive rate
of climb, the pilot should remember that in the take-off / initial climb seg-
ment, the margin above stall speed for many aircraft is fairly small, and
thus must be respected.
