I just realized the mistake I made :
UAS is for cabin alt > 10.000ft, not 14.000ft, so if dP stays at -1.0, for a cabin alt at 10.000ft:
AltCabin= 10.000ft
Pcabin= 10.11 PSI
dP= -1.0 PSI
Pstatic = 11.11 PSI
Alt a/c = 7500 ft
So in a perfect scenario, no leaks of the fuselage, just the perfectly working negative pressure relief valve, as long as Alt > 7500ft, masks must be on... in a perfect world....
