Patent ID: 8436750

Claim:
Method of monitoring a landing phase of an aircraft comprising means for generating alerts monitoring a provisional landing distance and a configuration of the aircraft throughout the changes in the landing phase maneuver, these means comprising an onboard navigation system, performance databases, meteorological measurement sensors and data acquisition means, comprising the following steps; a. determination of sub-phases forming the landing phase, from a runway approach phase onwards, in order to monitor the configuration of the aircraft and the flight parameters with each of the sub--phases, b. determination of a runway status condition by means of data originating from a plurality of meteorological measurement sources, a number of sources changing throughout an execution of the landing sub-phases, the meteorological measurement sensors being retained to determine the runway status conditions, and c. calculation of the provisional landing distance according to a braking performance chart comprising input parameters, runway status parameters, flight parameters and aircraft configuration parameters, the landing distance being re-assessed according to a trend of the input parameters throughout the changes in the landing sub-phases.
