Abstract:
1. A method for monitoring radioaltimetric heights of an aircraft, wherein from two distinct radioaltimeters, respectively, a first and a second radioaltimetric height are received relative to a same position of the aircraft, the method comprising: (a) determining an auxiliary height, using an on-board auxiliary source that is dissimilar and independent from the radioaltimeters, the auxiliary height being relative to the same position of the aircraft as the first and second radioaltimetric heights, and for determining the auxiliary height, the following operations are carried out: (b) checking the coherence between said first and second radioaltimetric heights; and (c) should an incoherence occur between the first and second radioaltimetric heights, determining the most reliable radioaltimetric height of the first and second radioaltimetric heights using the auxiliary height; and this determining including the following operations: (d) transmitting at least one of the radioaltimetric heights to at least one user device by performing the following operations:
