ABSTRACT:
In a warning system for aircraft that generates a warning signal when the aircraft is descending during a take-off or missed approach phase of operation, the warning is inhibited for a predetermined loss of altitude in order to allow the aircraft to descend a short distance without triggering a nuisance warning. Specifically, a circuit is provided to integrate a signal representing the aircraft's rate of descent until the integrated signal is equal to a predetermined drop in altitude whereupon the warning signal is triggered.
