Abstract:
1. A method for assisting in the management of an engine failure on a multi-engine aircraft, according to which method the engines of said aircraft are monitored during a flight in such a manner as to be able to detect any engine failure and, when an engine failure is detected during the flight, the following series of successive steps is automatically carried out: a) the current values of parameters relating to the aircraft, including its current position, are determined; b) a number n of airports that are the n closest airports to said current position of the aircraft (A) is determined, where n is an integer; c) for each of these n airports, a lateral trajectory is determined that allows the aircraft to fly directly to the corresponding airport starting from said current position; d) for each of these n airports, at least one flight profile is determined that is defined according to the corresponding lateral trajectory in accordance with a flight strategy, the flight profile comprising, in the vertical plane, an altitude profile and a speed profile along the corresponding lateral trajectory, and predictions are made relating to each flight profile; e) depending on at least some of said predictions, flight profiles not satisfying pre-determined conditions are identified; and f) all the airports are shown on a display screen of the aircraft with highlighting for those that do not satisfy said pre-determined conditions, together with the associated conditions.
