Abstract
A method for determining the quantity of fuel in an aircraft and an optimization criterion such as a cost index, notably used in an FMS, making it possible to maintain a time requirement of the RTA type, comprising a first step of computing the optimization criterion CIas a function of the aircraft weight GWvia a method of the RTA type and a second step of computing the weight of the aircraft GWas a function of the optimization criterion Ccomputed in the first computation step and the aircraft weight GW, executed by successive iterations, until the estimated flight time resulting from the computed parameters after the second computation step makes it possible to observe the time requirement to within a determined criterion δt, a last step determining the pair of values of aircraft weight GWand of performance criterion CIallowing an optimal fuel payload and the maintenance of the RTA.
