Oh dear....
instead of importing US spec cylinders which can't be legally filled or tested in Europe
Reference please bose x
I have been flying with oxygen, airways to FL190, for 3 years. Some basic facts:
- usually no way to get refilled away from base (don't I know it)
- usually no way to get refilled around Europe (likewise)
- the MH kit is good from the gas conservation angle (I've just been involved in very comprehensive airborne tests of different demand regulators) but that's not the whole picture
- the American 540 thread bottles are the most common by far
- having your own rented bottle from British Oxygen (with welding oxygen - it's all the same gas inside, only the paperwork differs) is the best and by far the cheapest way to refill your kit
- the cylinder pressure is a moot point since the only way to exceed 150 bar significantly is by having access to an oxygen boost pump, and by using special bottles and 1st stage regulators...
