Patent ID: 8849478

Claim:
A method for assisting aircraft piloting, the aircraft following a flight procedure comprising a lateral trajectory having an associated end of procedure position and vertical trajectory, the method comprising the steps of: determining a mean flyable slope that an aircraft is assumed to be able to fly, based on a value of a weight of the aircraft and on values of flight parameters associated with said flight procedure, said determining step being performed by a computer; the flight procedure being divided into a plurality of successive portions, each portion having an individual ground length on a lateral trajectory and a height, each said portion being chosen such that at least one of said flight parameters differs between at least two successive portions; the step of determining said mean flyable slope further comprising sub-steps for: calculating an individual slope for each said portion; and calculating an average of said individual slopes weighted according to the corresponding individual ground lengths, said average corresponding to said mean flyable slope; and presenting said mean flyable slope to a decision-maker by displaying a value of the mean flyable slope on a display screen.
