摘要:
A monitor for a flight control system provides an alarm and/or disconnects the system when pitch axis hardover failures occur, whereupon corrective action may be taken to insure flight safety during critical maneuvers. Apparatus is provided for inhibiting the monitor during control wheel steering of the craft and for an out-of-trim condition of the aircraft elevator. The monitoring range is extended by monitoring pitch rate during level turns of the craft.
摘要:
A circuit has averaging means for providing an output corresponding to the average acceptable input signals, a comparator for comparing each input signal to the average output, and switching means controlled by the comparator for eliminating unacceptable input signal from the average when the signals differ a predetermined amount from the average output.
摘要:
A system for controlling an aircraft during integrated glide path capture and tracking and flare maneuvers when automatically landing the craft. The system eliminates the need for explicit switching to initiate the flare maneuver and the flare control channel is effectively exercised during the glide path capture and tracking maneuvers to eliminate extensive pre-land testing that would otherwise be required if the flare control channel were switched on at low critical altitudes as has previously been the case.
摘要:
A fail operative control system equipped with dual unmonitored condition sensors which would otherwise render the system fail passive or fail safe. The fail operative feature is achieved in response to signals from the unmonitored sensors and a signal from another sensor, and which signal is essentially the first derivative of the signals from the unmonitored sensors.
