..except if you are lucky enough to have a flight engineer...
I recall an incident where the auto speedbrakes (Classic 747) actuated whenever the power levers were substantially advanced, by this time (at v/busy airport) we were almost at the holding point for takeoff.
After checking the MEL, the FE simply pulled the auto speedbrakes c/b, which solved the problem, and which only altered the landing procedure by having to manually deploy the s/brakes on touchdown. Simple and efficient!
Great job, that's one of the quite simple fixes that's stuck in my memory over the years, and there were simply to many to mention!
I'm simply nervous of non-FE manned extended distance flying...I guess I always will be!
