Highest legal altitude with PAX OXY MASKS failure
Only half a speed-brake
Lantrin, best of luck!
Trying to respect your RoE, FL140 from me.
On a type certified for flight above FL250 you shall provide O2 to 30% passengers after DX between FL140-FL150 and 100% pax above FL150. CAT.IDE.A.235 Table 1. Since you don't have the equipment anymore, choose a flight profile that satisfies the requirements.
Terrain and fuel shouldn't be a factor, solved already at the dispatch phase.
Well, perhaps not always. For non-LROPS flights, the 60 minutes distance requires only adequate airports so the actual WX might officially be poor. Then FL250 for endurance, if really required.
I think the inspiration from AMC1 CAT.IDE.A.235(e) is acceptable only if the appropriate rules cannot be followed due to overruling reasons. Not by choice.
