Rolf, if memory serves me right, the FARs are clear about it: setting

I don't recall any regulation requiring the altimeter to be set to QNH
unless the particular operation requires it (eg. an instrument
approach).

* 14 CFR 91.121 * (aka FAR 91.121)

* For extra credit, note 91.121(a)(1)(i) which says you must use the setting
from the local radio source in preference to setting to the field elevation.
As was pointed out in this group a couple years ago, the examiner in the back
seat knows that regulation.

Yeah, but as for 91.121 you're not maintaining any particular cruising
altitude or flight level when operating a glider. *I certainly agree
that cross country gliders should be operating off QNH but if you're
flying *locally, you should have the option of setting QFE. *I fly a
towplane and use QFE 99% of the time--any position calls I make I

Interesting. I also fly a towplane for a club and use QNH exclusively
- so when I call the glider release, it's MSL and doesn't need any
conversion (and associated potential for mistake). That call is a
safety-of-flight issue, IMHO - and not only for local club traffic,
but for any other aircraft passing by - and much more important than
reporting the tow height to the ground for billing purposes (which, in
our club, is not a tow pilot responsibility anyway - the member logs
it after the flight or gets charged a flat 3k ft tow...). As chief
tow pilot I don't want my tow pilots doing anything during their tow
flight that takes them away from clearing their flight path,
especially with lots of gliders milling around!
