Would you like for me to explain the oxygen system for the passenger or would it be easier for you to look it up?
Hint, there are NO oxygen bottles and for that matter NO oxygen carried on board the airplane for the passengers.. Depending on type of aircraft One or Two bottles for cockpit crew. There are portable oxygen bottles on board. 777 may have a dozen. Not sure the exact amount. Can be used between 15 and 30 minutes each depending upon the flow you select
Wow, I bet that blows your mind.
Hint. They are call oxygen GENERATORS. Ya cant turn them off. I dont want to have to explain. Just got to google type in "oxygen generator" + airplane. Am sure you can read all about it
Doesn’t really matter where the O2 comes from, the process has a off switch, I can guarantee it, in modern planes. The oxygen generators you speak of, they actually used a non-reversible process manually triggered.
Why are you so combative? The end result is that pure oxygen is released into the atmosphere. This is a fire risk.
Also, thanks for the suggestion on the Google search. The 777 uses oxygen bottles, not generators. Probably should take your own advice before attempting to smack someone down in the forums :)
