Hi this is a repost from the Tech Log forum...
Looking for anyone who could shine some light on this.....
Thanks
A320 Min Temp?? In the limitations section of the FCOM, the minimum air temperature indicated in the environmental envelope is SAT -70 C.
What exactly is the limitation for?? Is it structural? Fuel cold soak? Airconditioning? Hydraulics?
Recently we have encountered temperatures below this, -73C at flight level 380, there were no ECAM warnings and the wings didnt fall off... Now what are we to do?? Descend? Speed up?
Loads of other airbuses at the same and at higher levels with their wings still attached.
Is it safe to assume that Airbus could not find air cold enough to test in for certification? Or are we all about to have a nasty shock one day soon?
