Let's say the right wing body OVHT on a 737-400 is U/S, me as a pilot I have to operate with the right side isolated and OFF;is there anything you guys have to do apart from putting an INOP sticker on the light itself?
I'm asking because i have flown in such a condition but even if the DDPG procedure was applied the light would still come ON from time to time...quite a pain in the arse especially when it did during T/O roll....
Shouldn't it be deactivated in such cases?

thanks for that, but would a bulb removal prevent the master caution from coming on as well?Or would i get a master caution air cond without a sign on the overhead panel making my day even more confusing?

Removing the bulb would not prevent the master warning chime and lights from coming on. With no OVHT bulb, the only other clue would be the Air Con annunciator light.

There's no chime associated with a master caution on 737 A/C.
So wouldn't it be better to deactivate the whole right wing body ovht system?is it a possible solution?
