Patent Images
1. A safety method for aircraft comprising the steps of:
- marking prohibited airspaces, which controlled aircraft may not enter, on a digitally stored image of the airspace;
dividing the airspace into predetermined volume elements;
calculating probabilities in which the aircraft will be situated in predetermined volume elements at a plurality of selected points in time (residence probabilities);
calculating probabilities of the residence of the aircraft in each volume element (collision probabilities) of the predetermined volume elements for the selected points in time from the residence probabilities of the aircraft and from residence probabilities of the volume elements of the prohibited airspace, the latter of which are set to one;
calculating an alternative route if the collision probability exceeds a predetermined value for at least one volume element; and
automatically steering the aircraft on to the alternative route which is situated outside the prohibited airspace by means of an automatic control device on board the aircraft.

Abstract
This invention relates to a safety system for aircraft, wherein prohibited airspaces which aircraft may not enter are marked on a digitally stored image of the airspace, wherein the aircraft is provided with an automatic control device that automatically steers the aircraft on to an alternative route, which is situated outside the prohibited airspace, when the probability that the aircraft will enter the prohibited airspace exceeds a predetermined threshold value.
