Abstract:
A method for automatically determining an avoidance maneuver in an automatic collision avoidance system of an aircraft. A maximum kinematic acceleration envelope is determined by determining a multitude of avoidance maneuver angle kinematic acceleration pairs in a kinematic acceleration plane, and interpolating gaps between points, thus creating a curve. The curve is called maximum kinematic acceleration envelope. The curve may also be approximated by an analytical expression. An adjusted kinematic acceleration envelope is formed in the plane by forming a new envelope. The new envelope at each point laying closer to or at the same distance from an origin 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 maneuver angle. An avoidance maneuver angle is received for which a suitable bank angle and a suitable normal load is to be determined. Determining The magnitude of the kinematic acceleration a corresponding to the adjusted kinematic acceleration envelope for the avoidance maneuver angle is determined by reading the envelope curve, or if the curve is an analytical expression, calculating the curve by using the analytical expression. The normal load is determined based on the kinematic acceleration, and the avoidance maneuver angle. The bank angle is determined based on the kinematic acceleration and the avoidance maneuver angle.
