Agreed, but is there anything *legal* that suits your needs and yet is
certified above 10,000'? You don't really need O2 below that.

How about something proper, that's really small (fits behind the seat, etc.,
is easily removeable, and can be filled after each flight?

What have you guys got against a proper oxygen system?


1. Size
2. Weight

Especially in 2-seaters, a decent sized compressed O2 system eats into the
allowable cockpit payload and often takes up space the pilot would rather
use for something else.
