Abstract : A bank of comparators is used to control a logic circuit which indicates proper system operation when measured hydraulic reel motor control pressures are within normal limits for the current airspeed after hose deployment. Also, before such deployment, simulated test signals are applied to the comparators to ensure proper operation of the comparators and logic circuitry. Patents. (EDC)
