how many people flying at any one time?

I'm having trouble tracking down a statistic I'm after, thought you
knowledgable folks might be able to help. As the subject title says:
how many people are aloft in aeroplanes at any one time...?

Thanks for your time.

It varies.

Think, tracksterman, think! Where would these numbers come from? Do you
think that general aviation pilots report their passenger loads to Big
Brother? There is a remote possibility that someone could add up the
passenger manifests of the airliners in flight at a particular time and
report the total to Big Brother, but at what cost? And for what benefit?

If you want general aviation numbers, it should be easy to compute.
GAMA (www.generaviation.org) publishes stats on #'s and annual hours
of active aircraft. NTSB accident data (www.ntsb.gov) can be used to
derive the average # of occupants per aircraft, and by time of day if
needed.

Do you report your annual hours flown to the government (or GAMA, for that
matter)?

No, I mean 'how many people' - and it's a global figure I want rather
than a US one. Of course this would only ever be a (very!) approximate
number, but that's all I need - and it has been done before, because I
remember reading the figure a couple of years ago. Just having a
spectacular lack of success finding it online...

Doesn't matter. For one thing, the number of people in the air in GA
aircraft at any one time
are going to be insignificant compared to the number of people in
commercial aircraft, and
the latter number is going to be fairly easy to estimate. (This data is
probably available
somewhere, but you can always take the know number of flights each day,
assume an
average capacity and load factor, and come up with a reasonable
estimate.) If you want
GA numbers, you can get an upper bound by checking the registry to see
how many
aircraft are listed and what types, determine how many seats this
translates into, and
assume everyone is full and in the air at the same time. You know the
actual number has
to be much less that this, so now you start making assumptions and
approximations.

Isn't that on the medical application? It's also reported to
insurance companies; FAA and GAMA publish their analyses of activity
from the data. What's the problem?

Bob, reliable estimates of such things don't necessarily require exhaustive
counts. Carefully designed sampling works, too.
