Minimizing dynamic structural loads of an aircraft (2), introduced by an external excitation (1 ), which, comprises generating a signal (x) indicative of the external excitation (1 ); deriving signals (y) of pre-controlling for actuating control elements of the aircraft (2) from said excitation indicating signal (x) in accordance with a pre-controlling rule, so as to reduce the dynamic structural loads introduced to the aircraft (2); generating an error signal (e, e*) representing performance of said pre-controlling; optimizing the pre-controlling rule by said error signal (e, e*) and/or said excitation indicating signal (x) so as to minimize the dynamic structural loads.
