    摘要: A system and method for determining a lateral and vertical path for aircraft guidance from a current aircraft position to a landing runway following a complete loss of engine thrust includes determining, in a processing system, a final approach segment, a deceleration segment, and a driftdown segment. Connecting, in the processing system, the driftdown segment to the deceleration segment, and the deceleration segment to the final approach segment, to form a complete lateral and vertical path from the current aircraft position to the landing runway. And rendering, on a display device, a graphical representation of the complete lateral and vertical path from the current aircraft position to the landing runway, wherein the graphical representation of the complete lateral and vertical path updates as the aircraft travels.

    摘要: Diverse types of crew interfaces (400, 430, 450) are provided for outputting visible, audio and tactile information to a pilot for flight control. A unified estimation of the current aircraft state and of a current phase of flight are made (110), based on flight status information. Respective coordinated visible, audio and tactile presentations for the diverse types of crew interfaces are generated, (120) coordinated so that they provide mutually consistent indications of the unified estimation of the current aircraft state, according to the unified estimation of current flight phase. The respective coordinated presentations are output (130) by the diverse types of crew interfaces to the pilot. By coordinating crew interface outputs across sight, sound and touch senses, this can relieve the pilot of workload in interpreting unsynchronised or incoherent outputs from different types of interfaces.

    摘要: A method and apparatus for estimating an airspeed of a rotorcraft by analyzing its rotor. The rotorcraft includes a fuselage and a main rotor that is equipped with a plurality of blades and that rotates about an axis of a hub of the rotor, and in which the free end or “tip” of each blade describes a path in the vicinity of a tip-path plane. The method makes it possible to determine said airspeed of the rotorcraft in a frame of reference united with the tip-path plane by solving a model of the rotor that puts a pitch angle of at least one blade relative to the tip-path plane into relation with the airspeed of the rotorcraft and with an auxiliary speed. The auxiliary speed may be an induced velocity of the air flowing through the rotor or else an axial airspeed at the upstream infinity of the rotorcraft.
