ABSTRACT:
An improved aircraft altitude approach control device is characterized by both visible and audible indications of changes in the aircraft altitude as the aircraft descends to a landing. A transducer is provided on the aircraft which produces an output signal corresponding to the altitude of the aircraft. The output signal is converted to a digital signal and then to an analog voltage signal. A voltage controlled oscillator produces an audio frequency signal whose pitch corresponds with altitude. A further characteristic of the invention is the provision of a memory circuit in which a digital signal corresponding to a preferred landing is stored. This signal can be modified to produce a preferred or reference analog voltage signal. The actual and reference voltage signals are delivered to a glide slope meter which indicates differences therebetween. Thus, a pilot can gauge his landing approach relative to the reference or preferred landing approach.
