Abstract: Utilizing a three-wire input from a synchro, a signal representing the rate of rotation of the synchro shaft is generated by means of: summing amplifiers to generate signals representing the cosine of the shaft angle and the sine of the shaft angle; a circuit for generating a signal representing the tangent of the shaft angle; a circuit for generating the signal representing the cotangent of the shaft angle; feedback circuits for linearizing both the tangent and cotangent signals; a differentiator circuit for differentiating the tangent signal; a differentiator circuit for differentiating the cotangent signal; and a switching circuit for selecting the rate output from the differentiator with a linear output.

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.
