摘要： In order to reduce maintenance work and to improve long-time reliability, the invention provides a health monitoring method for checking a functionality of a flight control surface driving apparatus (104) using at least one load sensor (110) for sensing a load imposed on a control surface drive device (106), the method comprising at least one of the steps: a) blocking movement of the transmission device (108) by means of a brake device (118), b) commanding the control surface drive device (106) to apply a load on the blocked transmission device (108), and c) determining whether at least one load sensor output signal (62) of the at least one load sensor (110) is within a predetermined range. Further, a flight control surface drive apparatus (104), a flight control system (100) and an aircraft (10) comprising a control device (112) configured to automatic command conduct of such health monitoring method are described.

Further, a flight control surface drive apparatus (104), a flight control system (100) and an aircraft (10) comprising a control device (112) configured to automatically conduct such health monitoring method are described.
