Cabin depressurisation
I am looking for some advice.
My question is this: What happens to cabin temperature in the event of depressurisation at normal cruising altitude?
I am writing my thesis on Long Range Operations. Manufacturers are promototing the use of onboard oxygen generators to preclude a descent in the event of cabin depressurisation, the idea being that if the aircraft need not descend, it is permissable to fly over higher terrain, thus opening new routes for example over the Himalayas, where a descent to <10,000 feet is not possible. However, this is academic if the pax are going to freeze to death. Any opinions would be appreciated.
