Altimeter settings: QNH versus QFE

And what about computer folks?
They can't go further than 0 and 1!

Get rid of feet, knots and NM???

That may work for gliders, but not necessarily for other type aircraft. The
math is simple using the nautical system with lots of shortcuts to do the
math simply. Mach number means nothing to glider pilots (save the shuttle
dudes), but it does to us jet jocks.

Just another point in this discussion: when I look at an approach map of
an airfield, the pattern altitude is expressed as a height above
ground. To me, this means the easiest way of complying is to fly QFE
when entering the pattern (no mathematics needed) - providing of course
you can get the necessary information.

If you want to fly QNH, pattern altitudes should be expressed AMSL.

By the way, here in Europe (except UK, of course) glider altimeters are
in meters, not feet, thereby conforming to ICAO annex 5 whose purpose
it is to standardize units of measurement to the ISU. As the approach
maps (and other aviation maps) usually are in feet, we already have to
make computations anyhow.

It's high time we got rid of feet, knots and nautical miles! Their only
real purpose in aviation seems to be to make it more difficult to get a
pilot's licence, as you have to adjust to a new set of units. (Yes, I
know there are certain countries where they like to use outdated unit
systems. I also know the classical arguments like "a nautical mile
equals a minute of latitude", but how often do you fly true north or
south?)

All of the aruguing aside, can anybody out there tell

the history of QNH, QFE, and QNE (etc.), specifically,
WHAT does the

'E'???

Nothing. It's just a code, the Q-code, to be precise
:-) Maybe the Q has
a story, I don't know, but the latter two letters
definitely do not.
Think of it as a numbered set of commonly used phrases.

A complete list of all Q-codes is at http://www.htc.ch/de/der_Q_c

Don't forget the Z codes.

They are all simple codes originally sent by morse.
If you look at the
whole list there are loads of things to do with radio
comms as well as
the various things to do with aerial navigation.

They are widely used in amateur radio as well as in
flying.

Robin
Quite right. One may send quite a complex message
using a few Q & Z
signals, text, and numbers.

Thanks to all who've helped me understand the orign of the letters in
QNH, QFE, QNE, QUH, WTF...etc...

One of my aerospace co-workers (and a fellow Flight Test Engineer) was
musing aloud one day: "We all know what it MEANS, but what do the
letters STAND for??? Where did they come from?" As if QNH stood for
"Quintesstial Normalized Height," and QFE stood for "Quiet Field
Elevation," or ???

I tried to warn him that it was foolish to try and make sense out of
any three letters...take "FAA," for example... ;-)
