Automatic take-off method for e.g. cargo aircraft, involves determining deflection orders of elevator of aircraft from vertical steering point, and applying deflection orders to actuating unit of elevator

摘要

The method involves determining a vertical guiding point, which represents an angular profile along a pitch axis of an aircraft and obtains optimized performances based on take-off conditions e.g. wind, where the profile is expressed along a parameter e.g. attitude, of aircraft. A current value of the parameter is measured on the aircraft, and a vertical steering point which is expressed in pitch speed is determined from the point and the current value. Deflection orders of an elevator of the aircraft are determined from the steering point and applied to an actuating unit (11A) of elevator. An independent claim is also included for an automatic take-off device for an aircraft, comprising a vertical guiding point determining unit.
