Abstract: Prediction methods and systems including a central processing unit including a data acquisition unit configured to acquire experimental data of a parameter characterizing the time-dependent phenomenon, a data acquisition unit configured to acquire digital data of the parameter characterizing the phenomenon, and a data processing unit configured to combine the experimental data and the digital data, by using a proper orthogonal decomposition POD that makes it possible to obtain an effective prediction of the time-dependent phenomenon, combining the advantages of the experimental data (accuracy) and those of the digital data (spatial resolution).

Abstract: The present disclosure refers to a method for operating a landing gear system, preferably in a tricycle configuration, wherein main landing gear (MLG) and the nose landing gear (NLG) are operable from a retracted position where they are housed respectively inside landing gear bays, to a fully extended position where they are extended for landing the aircraft. According to the disclosure, the extension of the nose landing gear (NLG) is delayed in time with respect to the extension of the main landing gear (MLG), and the nose landing gear (NLG) is kept retracted during a major part of the time that the main landing gear doors (MLGD) are extended. In this manner, vibrations on the main landing gear doors are reduced and incidents caused by fatigue are also reduced, which in turn implies that the maintenance cost of the aircraft is greatly reduced.
