Aeronautical emergency danger zones

Aeronautical emergency planning zones based on the probability of impact in the vicinity of the airport, aerodrome or heliport. The models used allow the calculation of the probability that, given an accident in the vicinity of an aeronautical installation, the aircraft will impact at a specific point. Two types of zone are defined: Zone I corresponds to the territory with a probability of impact greater than 10% (10e-1) and Zone II corresponds to the territory with a probability of impact greater than 1% (10-2).
