A method and system for managing data from an aircraft radio-altimeter. The data management system includes a monitoring unit for checking, automatically and repetitively, when the radio-altimeter is outside of its operational range, from data generated by the radio-altimeter for a predetermined duration, whether the trend of the data corresponds to an aircraft approaching the ground, and a data transmission unit configured to automatically transmit the data generated by the radio-altimeter to a user system, only if the monitoring unit considers that the trend of the data corresponds to an aircraft approaching the ground.

1. A method for managing data from an aircraft radio-altimeter, the aircraft radio: altimeter having an operational range and being suitable for generating data corresponding to radio-altimetric heights and for determining whether it is within its operational range or not, the method comprising: a monitoring step comprising checking, automatically and repetitively, when the aircraft radio-altimeter is outside of its operational range, from data generated by the aircraft radio-altimeter for a predetermined duration, whether a trend of the data corresponds to an aircraft approaching ground or the trend of the data corresponds to the aircraft flying over a different object; anda data transmission step comprising: disregarding the data generated by the aircraft radio-altimeter if the monitoring step considers that the trend of the data corresponds to the aircraft flying over the different object; andtransmitting, automatically, the data generated by the aircraft radio-altimeter, only if the monitoring step considers that the trend of the data corresponds to the aircraft approaching the ground. 2. The method as claimed in claim 1, wherein the monitoring step further comprises: from the data generated by the aircraft radio-altimeter, determining a vertical speed; andconsidering that the aircraft is approaching the ground, only if the determined vertical speed is negative for the predetermined duration. 3. The method as claimed in claim 1, wherein the monitoring step further comprises: determining a vertical trend of values of an auxiliary datum;comparing the vertical trend to the trend of the data generated by the aircraft radio-altimeter for the same duration; andconsidering that the trend of the data corresponds to an aircraft approaching the ground, only if the vertical trend and the trend of the data generated by the aircraft radio-altimeter are similar. 4. The method as claimed in claim 3, wherein the auxiliary datum is one of the following data: an inertial datum;a barometric altitude datum; andan altitude datum derived from a satellite positioning system. 5. The method as claimed in claim 1, wherein: when the aircraft radio-altimeter is outside of its operational range, the monitoring step is repeated until the trend of the data corresponds to an aircraft approaching the ground; andwhen the monitoring step considers that the trend of the data corresponds to an aircraft approaching the ground, implementation of the monitoring step is stopped, until the aircraft radio-altimeter is once again outside of its operational range. 6. A system for managing data from an aircraft radio-altimeter, the aircraft radio-altimeter having an operational range and being suitable for generating data corresponding to radio-altimetric heights and for determining whether it is within its operational range or not, the system comprising: a monitoring unit configured to automatically check, when the aircraft radio-altimeter is outside of its operational range, from data generated by the aircraft radio-altimeter for a predetermined duration, whether a trend of the data corresponds to an aircraft approaching ground or the trend of the data corresponds to the aircraft flying over a different object; anda data transmission unit configured to automatically transmit the data generated by the aircraft radio-altimeter, only if the monitoring unit considers that the trend of the data corresponds to an aircraft approaching the ground,wherein the data transmission unit is further configured to disregard the data generated by the aircraft radio-altimeter if the monitoring unit considers that the trend of the data corresponds to the aircraft flying over the different object. 7. The system as claimed in claim 6, wherein the monitoring unit comprises: a data processing element configured to automatically determine, from the data generated by the aircraft radio-altimeter, a vertical speed; anda computation element configured to automatically deduce that the aircraft is approaching the ground, only if the vertical speed is negative for the predetermined duration. 8. The system as claimed in claim 6, wherein the monitoring unit comprises: a data processing element configured to automatically determine a vertical trend of values of an auxiliary datum; anda comparison element configured to automatically compare the vertical trend to the trend of the data generated by the aircraft radio-altimeter and to consider that the trend of the data corresponds to an aircraft approaching the ground, only if the vertical trend of the value of the auxiliary datum and the trend of the data generated by the aircraft radio-altimeter are similar. 9. A radio-altimetric data generation assembly comprising an aircraft radio-altimeter, and a data management system as claimed in claim 6.
