The invention provides a method of dynamically alleviating loads generated on an aircraft (2) by a disturbance of gust and/or turbulence, the method comprising the steps of: on a flight of the aircraft (2), a monitoring is applied for automatically detecting a disturbance due to gust and/or turbulence and determining an incidence angle of the disturbance; when a disturbance due to gust and/or turbulence is detected, automatically generating control commands (36; 32, 38, 40, 42) for deflecting control surfaces dependent on the incidence angle; and applying the control commands (36; 32, 38, 40, 42) to deflect the control surfaces. For optimizing the performance, it is proposed to conduct at least one of the following step sequences A) and/or B): A) adapting the control commands (36; 32, 38, 40, 42) not only to the amount of the incidence angle but also to the gust length in order to adapt the deflection of the control surfaces both to the incidence angle and the gust length; and/or B) generating first control commands (y, 34; 32, 38) for first control surfaces and second control commands (36; 32, 38, 40, 42) for second control surfaces, comparing the incidence angle with a predetermined value and generating the first control commands (y, 34; 32, 38) to actuate the first control surface until the incidence angle reaches this predetermined value and generating the second control commands (36; 32, 38, 40, 42) to add a deflection of the second control surfaces when the incidence angle is above the predetermined value.
