Active sidestick technology – a means for improving situational awareness

The use of an active sidestick in FBW-flight control is discussed and the specific features of both passive and active sidesticks are compared. Additional tactile information which could be provided by active sidesticks is seen as an important factor to improve the situational awareness of the pilot. An unique active sidestick concept based on the electro-magnetic actuation principle (electro-magnetic sidestick, MAGSI) is presented. This system is the key element in DLR's research programme EPIAS (Enhanced Pilot Information by using Active Sidestick) which is scheduled to be flight tested on the ATTAS (Advanced Technologies Testing Aircraft System) in-flight simulator at the beginning of next year.
