Oxygen - ANO question
I'm trying to find the regulations for oxygen requirements on GA flights but the CAA search engine is throwing up too many returns for the various terms I've tried.
I know the regs for flying crew to be on oxygen for any sector greater than 30 mins above FL100 and below FL130 and oxygen continuously above that. What I'm trying to find are the criteria for oxy systems applicable up to & inc FL200.
The a/c I want to fly is a TB21 with a time expired oxy system on the bottle which the manufacturer no longer makes (Puritan Bennett). The cost of recertification of a new bottle is prohibitive so I want to know what options are available for portable oxygen and the rules for cannulae vs masks, certification if any of portable bottles etc.
Does anyone have any pointers or experience with portable systems in GA a/c between 10 and 20 thousand feet?
