VERMEIDUNGSMANÖVER-GENERATOR FÜR EIN FLUGZEUG

A method for automatically determining an avoidance manoeuvre in an automatic collision avoidance system of an aircraft, the method comprising the following steps: - determining a maximum kinematic acceleration envelope by determining a multitude of avoidance manoeuvre angle - kinematic acceleration pairs ((µ, ±)-pairs) in a kinematic acceleration plane, and interpolating the gaps between points, thus creating a curve, this curve is called maximum kinematic acceleration envelope, the curve may also be approximated by an analytical expression; - forming an adjusted kinematic acceleration envelope in said plane by forming a new envelope, the new envelope at each point laying closer to or at the same distance from the origin (0,0) as the points of the maximum kinematic acceleration envelope and such that there is only one value of the kinematic acceleration a for a given avoidance manoeuvre angle µ; - Receiving an avoidance manoeuvre angle µ for which a suitable bank angle and a suitable normal load is to be determined; - Determining the magnitude of the kinematic acccleration ± corresponding to the adjusted kinematic acceleration envelope for the avoidance manoeuvre angle, by reading the envelope curve, or if the curve is an analytical expression, calculating it by using said analytical expression; - Determining the normal load n z , based on the kinematic acceleration ±, and the avoidance manoeuvre angle µ; - Determining the bank angle based on the kinematic acceleration ±, and the avoidance manoeuvre angle µ;
