By the way, the Fl limitation for the bleed fault does only apply to some older MSNs. I experienced a single bleed overheat (which could not be reset) recently, we checked our MEL and found that for the MSN we were in there was no Fl restriction if the speed brakes are operative, but on some of our older aircraft to Fl 315 - I don't know why they have a different restriction, maybe it has to do some thing with the engine type (our older aircraft are IAE powered, the newer ones are CFM) or something else, maybe somebody else knows why this is this way...
