Then come back try again after the coffee.
The gist is give it time.
Interesting. I'm wondering what sort of failure would result in a return to normal operation after waiting several minutes particularly having established that the FSEU removes hydraulic power when asymmetry or skew is sensed.
For info, my airline operates NG and Max when not grounded and I have never flown older versions.
Further reading on this issue highlights more questions about how to handle this situation.
Our up coming sim profile calls for a diversion to our takeoff alternate following the flap asymmetry after takeoff.
The only QRH reference is to set the flap handle to the nearest detent that is equal to or less than the smallest indicated flap position. In our case that would be flap lever to 2 as the takeoff would have been flaps 10.
Does this imply the lever must remain at position 2 or is it permissable to place the lever at 0 for the diversion in order to retract all LE devices.
Cheers.
