ABSTRACT:
An optoelectronic device designed to facilitate the piloting of an aircraft under conditions of poor visibility, at take-off and in the event of an interruption of approach procedures through a wave-off maneuver. It consists of a collimator displaying, in addition to the artificial skyline, the aircraft model and the ground speed vector, two take-off and wave-off slope scales inclined symmetrically along the arms of an X laid on the artificial skyline and intersecting at a value of pitch attitude called a safety pitch attitude to be maintained in the event of engine failure, a local horizon locked into the aircraft model and two pointers that identify the safety pitch attitude and frame the artificial skyline when the pitch attitude of the aircraft corresponds to the safety pitch attitude. Through these new graphic symbols, the pilot can examine the pitch attitude of the aircraft and its roll attitude without taking his eyes off the aircraft model. This makes it easier for him to pilot the aircraft at take-off and during wave-off maneuvers with or without engine failure.
