the RAT probe being heated on the ground meant that the plane ''thought'' it was in the air. Pulling the RAT heater CB didn't do anything to the ground control relay etc. THE PLANE ALREADY THOUGHT IT WAS IN THE AIR and another CB didn't need to be pulled...
Thanks and, yes your earlier input had stuck in my mind. So I assume that there is no redundancy and with a faulty WOW switch the TOCW would be U/S? Is this normal on all aircraft types?
