I presume this is an FAA rule.  I have been in the cockpit a number of times
on British registered aircraft when the plane and crew have met either or
both these criteria, and have never seen the oxygen mask in use.  In fact
I have never seen it available - i.e. sitting next to the seat which makes
me wonder just how quickly it could be put on.
