And its use to a method and apparatus for carrying out the test flight of at least once in the aircraft

摘要

The device of this invention as for (1), at least one rudder (2A, 2B and 2n) with, the control unit which gives deflection command to these rudders responding to (4) and this rudder deflection command, the expedient which measures the recovery quality which shows the development of the movement of the aircraft (6) and, in order the expedient which records with the recovery quality which at least corresponds with one which is given deflection command (7) with, for recovery quality to be maintained, the servo control means which the aircraft the trigger are done (13) with it consists of, in the above-mentioned control unit (4), it obtains the recovery quality which at least can identify one aerodynamic study effectThe expedient which makes the rudder deflection command cause which was induced the expedient which receives the recovery indication which can do thing (10) with, by the recovery indication (11) with is provided.
