Who's flying out of the higest elev airport?

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

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

Hey, you mountain types out there :-) I'm doing some research on a
safety
issue and need your help . I need a post from someone flying out of
Colorado
somewhere, preferably Telluride or a field very close to Telluride. I
need
as close to the highest elevation in the U.S. as I can get.
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.

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.

Dudley:

I fly out of FTG (5500 MSL) in Denver. Having not much else to do
this week, I'll fly down to COS (6200) and see what happens with
the Kollsman. Difficult to get to Leadville right now (altho
it's only about 100 m from COS due to the high winds. Over
the weekend the winds in the mountains were clocked at 125 mph
in some areas. No passes for me right now!

Hi Blanche;
Actually, if our data is correct as of this point, at 5500 feet you
shouldn't be able to zero the altimeter at FTG, without having to go all the
way up to COS in all that nasty wind :-)))

Next time you're out at FTG, try it for me will you? I don't think the
Kollsman will let you do it if the low range maximum is 27.5 where I think
it is!
Thanks much,
Dudley

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.

You don't have to fly down there. Your altimeter goes down to 28.10.
You know the field elevation is 6200. Altimeter setting right now at
COS is 30.53. Therefore when set to 28.10 your altimeter will read
approx 3770.

Dudley,
Interesting that the "right or wrongness" of the issue is of such a concern.
Isn't it funny how different cultures view the same problem with different
perspectives? Here in the UK, no motorcycle rider would even think of
getting on a bike without a full set of leathers, helmet, and gloves. In
the States, guys ride in shorts, sneakers, and no helmets where they can.
On the other side of the coin, Brits "filter" through traffic on
motorcycles, riding between lanes just to get through traffic faster,
whether it be in the city or the highway. Most Americans think that's too
dangerous to think about.

Here in the UK, setting the altimeter to field elevation, QFE, before
takeoff is not only allowed, it's taught and expected. Likewise, when
approaching the airfield, you're expected to reset the altimeter to that
airfield's QFE in the pattern. In the States, we would think that would
lead to all kinds of altitude-related accidents.

Different perspectives, but who's to say what's right and wrong?
