Who's flying out of the higest elev airport?

Hey, I live at 3650 and can't set my altimeter to zero.

I'm not dealing with this issue in the context of right or wrong as it
pertains to mountain flying. I need to know if the Kollsman window in your
altimeters has a wide enough range to allow you, IF YOU DESIRED TO DO SO, to
set your altimeters to 0 elevation on a consistent basis before take off at
your field instead of a MSL setting. Again, I'm only interested in the
possibility, not the right and wrongs involved with doing this.

Thanks Newps; that jives with what I have so far anyway. I'm assuming a 27.5
low end on the Kollsman. Does that sound right to you. I'm at home and can't
check it :-)

I was just at the airport today and I looked at my new overhauled United
altimeter. The lowest setting is 28.10. There is a little travel past
that but you'd have to guess at what the setting really is. The station
pressure here is usually around 26 inches. Looks like the highest
altitude for which you could correct to zero will be about 2000 MSL,
depending of course on the actual altimeter setting.

I have it at present somewhere between 2500 and 3000 feet ASL as a possible
limit parameter based on averaging out the altimeter settings for the U.S.
It's interesting about the low Kollsman number range. With 28.10, I'm
beginning to see some variables in the low range that I didn't know was
there. I always assumed all the Kollsmans would all be the same. It will be
interesting to see if others have different numbers for their Kollsmans.

Dudley, I found reference to an air data computer which would accept an
altimeter setting of 26.75 to 33.00.

Thanks Stan; that's an additional data point for sure.

I'm not flying out of a high mountain airport (at the moment), but I
can tell you that most of GA aircraft altimeters I've seen only adjust
down to about 28.00. This makes setting a "0" elevation troublesome
above 2500 ft. MSL.

That's about what I'm getting also John. Thanks.
What I actually needed to know was the lower range on the Kollsman, which is
turning out to be just about where you have it at 28. I actually have it at
27.5 at this point, but considering averages, this puts the max 0 set about
where you are with it.

For some reason, Dudley, your query reminds me of the old joke "How thick is
the atmosphere?" The answer, of course, is "100 miles, but don't tell the
pilots -- they think it is only 29,920 feet thick on a standard day."

I don't have any direct experience with the airports in CO, but my pilots
guide shows LXV (Lake County Airport, Leadville, CO) is at 9,927' MSL. TEX
(Telluride Regional Airport) is 9,078' MSL.

The highest airport I've landed at is TVL (South Lake Tahoe, CA). The
alitude there is 6,264' MSL. None of the aircraft I flew to TVL (C172,
C182, RALL) had an altimeter which could have been set to indicate 0' at
that altitude.
