sunake Posted February 9, 2022 Report Share Posted February 9, 2022 It probably happens because you moved the controls before hydraulic power is applied. I haven't experienced it yet but you can get rid of it by powering down the aircraft completely (the fms should save all its data for a little while). Or, you can try to pull and reset circuit breaker CB3-C6. I don't know if that will work but try it. 1 Quote Link to comment Share on other sites More sharing options...

CaptCrash Posted February 9, 2022 Report Share Posted February 9, 2022 The aileron pcu jam can be triggered when you move the flight controls and there is some hyd pressure in the system but no pumps on. The simple fix is a power cycle of the aircraft to reset the jam sensor. 1 Quote Link to comment Share on other sites More sharing options...
