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 CIi as a function of the aircraft weight GWi-1 via a method of the RTA type and a second step of computing the weight of the aircraft GWi as a function of the optimization criterion Ci-1 computed in the first computation step and the aircraft weight GWi-1, 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 GWi and of performance criterion CIi-1 allowing an optimal fuel payload and the maintenance of the RTA.
