Are you talking about a B-767 here? If you get a "No Cooling" condition, the EFIS is guaranteed to work for no more than 90 minutes due to overheating. This is obviously most significant on an ETOPS segment, and will end up requiring diverting to the closest suitable field due to the potential for total EFIS failure. Incidentally, I have flown about 3,000 hours in the 757/767 and have never had this occur.

Hope that helps. If you need more I would have to break out the books!

The B757.
Was going thru MBF.com & read about the option if certain Equipments are installed.
