Comparing with the central stick/wheel or the active sidestick,the major disadvantage of the passive sidestick is the lack of back-drive mechanism,which leads to the loss of human-machine interactive information and the pilot/copilot interactive information,hence increasing the possibility of human errors.Without the feedback force from the sidestick,pilots have no direct tactile information,which will affect the distribution of human and machine control authority.In the design of civil aircrafts,it is suggested that a control mode switch be added to the passive sidestick,to make a balance between keeping the pilot's override authority and providing the effective envelope protection.Since there is no linkage between the left and right sidesticks,unfavorable dual inputs will more likely occur.In the design of civil aircrafts,it is suggested that the visual,aural and tactile cues should be provided to the pilots synthetically,and the use of existing successful takeover operating procedure to increase the pilot's adaptability.
