I'm not trying to pick an argument or put you down. I AM saying that different jurisdictions have different interpretations and standards.
Under JAR or the UAE GCAA (Which is JAR complient) you must be able to supply passengers with oxygen for the entire time above 140 in the event of a depressurisation, no matter how unlikely that depressurisation is.
You stated that you could not fly a paricular route on one pack because of the increased likelyhood of a depressurisation. I simply telling you that under some sets of rules it makes no difference how many packs are operating.
I do NOT know, or care less, what jurisdictions you operate under.
I have for some 40 years operated Worldwide with ONLY Australian registered Aircraft under Australian regs.
Also I did NOT ever say we could not operate a flight because we only had one pack?
IF you are going to start arguments or put people down at least learn to read first.
