flight attendant o2
Compressor stall or Lancer,
Understand that the EDTO area is unrelated to O2 in the first instance. But on the day, can you launch knowing that you have insufficient O2 on board to cover your contingency planning?
I think that was what raised the question about continuing depressurised at FL140 provided you had sufficient flight crew O2. I think the question that has been ignored is what O2 do the FAs need at FL140?
