d Should I carry oxygen for 10,500ft?
It is not required by regs. I do not use oxygen at that altitude.
However, some people have reported, especially at night, diminished
performance at that altitude (in fact, even above five thousand). I


one thing I have noticed though (bought a portable oxygen system
and was experimenting a bit) is that even when flying lower than
at altitude at which supplemental oxygen is required, using it
reduces fatigue drastically especially on a long cross country;
i.e., if you have an oxygen system and are going on your
first really long x-country, why not take it along? won't
hurt.
