ABSTRACT:
Check device for a redundant flight control apparatus comprising at least two servo drive devices. Failure in supplying fluid and wedging of a control valve (20) can be simulated. Failure of the bypass valve (35) can be checked by reading and comparing the volume flows of the respective pumps as well as by evaluating the travelling rate of the servo drives (1, 2) by the pilot.
