Abstract:
1. A method for estimating a degradation in performance of an aircraft during flight, the method performed by a computing device comprising: a) acquiring, using the computing device, in real time data comprising at least air and inertial data and satellite positioning data, said air, inertial data, and satellite positioning data being solely associated with the same aircraft, wherein, in addition to step a), the following sequence of steps are carried out in an automatic and repetitive manner: b) readjusting, using the computing device, the air and inertial data of the same aircraft is carried out with the aid of said satellite positioning data; c) calculating, using the computing device, at least one numerical value of the effect of a degradation in performance of the same aircraft based on a fuel consumption parameter and a drag parameter, both said parameters related to the same aircraft, by comparing the current state of said fuel consumption and drag parameters, which are calculated starting from said re-adjusted air and inertial data with the aid of at least one performance model, with a theoretical state of said parameters; and d) displaying said at least one numerical value being calculated of the effect of a degradation in performance based on said parameters on at least one screen in a cockpit of the same aircraft.
