Old news.
I’m refilling for years from welder’s oxygen.
Good article even though it is from 1999 – as Deakin says, it’s all the same stuff, some old fossil regulations notwithstanding.
The bit about needing a bit of moisture is also not an issue if you use cannulas, because most of the gas inhaled is just air getting past the cannula, with whatever moisture that has (which admittedly can be pretty low at high altitudes where, in VMC, the RH seems to be really low).
If you used a sealed mask then it would be an issue, but even the “aviation” masks used in GA have a valve which lets in a load of outside air.
I have been using welding oxygen since 2003. Details here
Hi guys
As of end of august, a new eu regulation will become effective in many countries. Apparently a lot of changes.
What I am particularly interested is the use of portable Ogyxen in non commercial operation in powers aircrafts less than 2t MTOW.
it says basically ‘additional oxygen’ but doesn’t specify which. I often hear the 18000ft you need to wear a mask…but that’s US. I haven’t found anything in the easa papers? Please advice
!
Here it says
It’s up to the pilot???
You’ve found the new guidance material, but not the implementing rule it supports. Part-SPO applies to specialised commercial operations (aka aerial work). The revisions to Part-NCO, which apply to non-commercial operations in most light, propeller driven aircraft, say:
‘NCO.OP.190 Use of supplemental oxygen
(a) The pilot-in-command shall ensure that all flight crew members engaged in performing duties essential to the safe operation of an aircraft in flight use supplemental oxygen continuously whenever he/she determines that at the altitude of the intended flight the lack of oxygen might result in impairment of the faculties of crew members, and shall ensure that supplemental oxygen is available to passengers when lack of oxygen might harmfully affect passengers.
(b) In any other case when the pilot-in-command cannot determine how the lack of oxygen might affect all occupants on board, he/she shall ensure that:
(1) all crew members engaged in performing duties essential to the safe operation of an aircraft in flight use supplemental oxygen for any period in excess of 30 minutes when the pressure altitude in the the passenger compartment will be between 10 000 ft and 13 000 ft; and
(2) all occupants use supplemental oxygen for any period that the pressure altitude in the the passenger compartment will be above 13 000 ft.’;
Part-NCO was amended on July 22nd by COMMISSION REGULATION (EU) 2016/1199 (for some reason I cannot find it on the EASA web site)
Old version:
NCO.OP.190 Use of supplemental oxygenThe pilot-in-command shall ensure that he/she and flight crew members engaged in performing duties essential to the safe operation of an aircraft in flight use supplemental oxygen continuously whenever the cabin altitude exceeds 10 000 ft for a period of more than 30 minutes and whenever the cabin altitude exceeds 13 000 ft.
New version:
NCO.OP.190 Use of supplemental oxygen
a) The pilot-in-command shall ensure that all flight crew members engaged in performing duties essential to the safe operation of an aircraft in flight use supplemental oxygen continuously whenever he/she determines that at the altitude of the intended flight the lack of oxygen might result in impairment of the faculties of crew members, and shall ensure that supplemental oxygen is available to passengers when lack of oxygen might harmfully affect passengers.
b) In any other case when the pilot-in-command cannot determine how the lack of oxygen might affect all occupants on board, he/she shall ensure that:
1) all crew members engaged in performing duties essential to the safe operation of an aircraft in flight use supplemental oxygen for any period in excess of 30 minutes when the pressure altitude in the the passenger compartment will be between 10 000 ft and 13 000 ft; and
2) all occupants use supplemental oxygen for any period that the pressure altitude in the the passenger compartment will be above 13 000 ft.
Cool
Thx
But it doesn’t specify mask or canulas?
bookworm beat me to it
