Deltahotel,
your response brings up a good point, if the flaps are set at 30, which is not a takeoff flap setting, will that switch engage? The genesis of my question stems from an event at my airline where a crew mistakenly set CLB 2 in the Thrust Management panel. When they pressed the THR switch at the start of their takeoff roll it wouldn’t engage. They manually set the thrust levers to the Caret (which was CLB 2) and almost had a tail scrape. I have flown other aircraft that have a takeoff light which will only illuminate when certain takeoff parameters and settings are met. The 757/767 has no such system, but I explained to my F/O that if the THR switch doesn’t engage when pressed at the beginning of your takeoff roll, there may be a good reason why. I’m just trying to tap into the great minds at PPRUNe to see if anyone knows more about this system. The manuals leave a lot to be desired.
