Patent ID: 8489257

Claim:
A method for actuating an elevator adjusting drive for adjusting an elevator and a moveable tail adjusting drive for adjusting a moveable tail comprising steps of: generating an elevator command to actuate the elevator adjusting drive; calculating a calculated moveable tail command for actuating the moveable tail adjusting drive in such a manner that the moveable tail is tracked to a calculated elevator signal input; depending on the adjusting states of the elevator and/or the moveable tail or flight states, with a commanded moveable tail command retaining the adjusting state of the moveable tail adjusting drive or actuating the moveable tail adjusting drive such that the adjusting state of the moveable tail is changed, during actuation of the elevator adjusting drive with the elevator command for changing the adjusting state of the elevator and in the event of a deviation of the calculated moveable tail command from the commanded moveable tail command, achieving neutral aerodynamic effectiveness by acting upon the elevator command to compensate for the retention of the adjusting state of the moveable tail adjusting drive or for the actuation of the moveable tail adjusting drive.
