Abstract
The device (1) comprises means (15) for computing deviations of a flight parameter with respect to a reference flight plan, by taking account of predictions, respectively for a plurality of flight data representing different origins, and display means (5) for simultaneously presenting the set of said deviations on a screen (6) of the flight deck of the aircraft, each time indicating the corresponding origin.
Claims15
A method for assisting the mission tracking of an aircraft, according to which method, in the course of a flight of said aircraft, in an automatic manner:
- the actual values of parameters relating to said aircraft are measured;
- for at least one flight parameter, deviations of said flight parameter with respect to a reference flight plan relating to a reference mission are computed, doing so by carrying out, for each of a plurality of flight data representing respectively different origins of deviations, each time the following operations:
- a prediction is carried out at the current flight point of said flight parameter, on the basis of the flight plan actually flown, taking account of said measured actual values;
- and
- the deviation is computed between this prediction obtained on the basis of the flight plan actually flown and the value of said flight parameter that is representative of said reference flight plan, this deviation thus computed being a deviation of said flight parameter relating to the corresponding origin;
- and
- the set of deviations thus computed for said flight parameter is presented simultaneously on a screen (6) of the flight deck of the aircraft, each time indicating the corresponding origin.
A device for assisting the mission tracking of an aircraft, said device (1) comprising:
- means (10) for retrieving and processing a reference flight plan relating to a reference mission;
- means (2) for measuring the actual values of parameters relating to the aircraft, in the course of a flight of said aircraft;
- computation means (15) for computing, for at least one flight parameter, deviations of said flight parameter with respect to a reference flight plan relating to a reference mission, said computation means (15) comprising elements for carrying out, for each of a plurality of flight data representing respectively different origins of deviations, each time the following operations:
- carrying out a prediction at the current flight point of said flight parameter, on the basis of the flight plan actually flown, taking account of measured actual values;
- and
- computing the deviation between this prediction obtained on the basis of the flight plan actually flown and the value of said flight parameter that is representative of said reference flight plan, this deviation thus computed being a deviation of said flight parameter relating to the corresponding origin;
- and
- display means (5) for presenting on a screen (6) of the flight deck of the aircraft, simultaneously the set of deviations thus computed for said flight parameter, each time indicating the corresponding origin.
