Hi,

I have just added the new Butterfly Vario to my web site. *It is a very
impressive new vario with FLARM display (when attached to a FLARM), GPS
flight recorder, simple navigation, simple final glide, artificial horizon,
and many other very nice features. *You can see details hehttp://www.cumulus-soaring.com/butterfly.htm

Good Soaring,

It will be worth informing your customers that fly in US sanctioned
contests that this instrument, as described, will not
be legal for use in US contests due to the incorporation of the
artificial horizon.

Horizon:
- the artificial horizon can be deactivated in a secure manner (tamper-
rpoof, just like IGC logging)

Stupid question - the second in as many days on RAS from me - Why is
an artificial horizon illegal? I read it in the rules but the "Why?"
is never included.

It would permit flying into clouds? Bad for obvious safety reasons I
suppose, and someone might be tempted to purposely be sucked up into a
thunderhead to pop out the top and then final glide the entire task!

I believe cloud flying in US contesst is no longer allowed.

No it isn't but that rule is not, and cannot, be enforced. If it was
some very well known pilots would lose their standing.

I'm not talking about being 950ft below when the regulations require
1000ft below (substitute 450/500 for East coasters) but deliberate
entering of a cloud layer for competitive advantage.
