ABSTRACT:
The invention concerns a method for preventing airplanes from impermissibly approaching defendable ground objects, the method suggests that a defendable ground object is assigned a virtual prohibited zone spatially surrounding it, with the outer boundary of such zone being provided with a sufficient horizontal minimum distance from the ground object and a vertical minimum distance determining a given minimum crossing altitude, that the prohibited zone is assigned a virtual correction zone laterally surrounding it whose outer boundary has a horizontal minimum distance from the outer boundary of the prohibited zone in any case sufficient for any forced deviation corrections and an altitude equal to that of the prohibited zone; that the correction zone is assigned a virtual alarm zone spatially surrounding it whose outer boundary has a horizontal minimum distance from the outer boundary of the correction zone in any case sufficient for manual deviation corrections; that the geographical data of the outer boundaries of at least the alarm and the correction zone are recorded and digitally stored together with the vertical minimum distance or the minimum crossing altitude and stored with access protection provided in every airplane and displayed in the cockpit.
