Pif Paf, are you saying that if you loose one pack after takeoff you should not climb above FL250?
Checkboard,
maybe it's useful to highlight that the problem is not much in being relatively safe below FL250, while above that level most of the passengers would die.
Nobody would remain at those altitudes after a decompression.
What the authorities want is to limit the TIME it takes, assuming max descent rate of your type of aircraft, to reach 14000 ft.
I'm probably wrong, but maybe an airplane capable of descending at an amazing rate would be cleared to a higher level on a single pack.
Standing to be corrected!
