Abstract

See full text

An estimation unit including an element for computing an actual distance, representing the distance covered by the aircraft over at least one speed interval delimited between two speeds of the aircraft, the interval corresponding to rollout on a segment of the runway, for which the braking performance of the aircraft is limited by the friction of the runway, an element for computing a plurality of so-called reference distances corresponding to various runway states, an element for comparing the actual distance with the reference distances, and an element for selecting, on the basis of these comparisons, one of the reference distances, the runway state which corresponds to the reference distance thus selected representing the runway state determined by the device.
