Abstract: In a system where the aircraft''s distance below a radio glide slope is compared with the aircraft''s altitude above ground to generate either an advisory voice warning or a command voice warning depending upon the aircraft''s altitude and distance below the radial glide slope beam, the repetition rate of the advisory voice warning is varied as both a function of distance below the radio glide slope beam and of altitude in order to generate advisory warnings at a rate reflecting increasing danger to the aircraft. This is accomplished by integrating the glide slope deviation signal over time and comparing it with a radio altitude signal so as to generate a signal for triggering the advisory warning as a function of the glide slope deviation and the radio altitude thereby generating the advisory warnings as a function of decreasing radio altitude and increasing deviation from the glide slope.

Abstract: In order to provide for the additional effectiveness of a ground proximity warning system during a landing approach, the waypoint signal of an Area Navigation System is used in combination with an altitude above-ground-signal to compute a minimum terrain altitude for each point along the aircraft''s approach to the runway. The minimum altitude is compared with the aircraft''s actual altitude and if it is below the minimum an alarm is activated.
