2007 US Contest Rules

Have they been published yet? All I can find are the 2006 ones. I know
there are significant changes in the scoring formulae and have seen the
proposed documents.

Where and when are the actual rules going to be finalized? It is almost
time for the first contest.

Larry, you know better - The first contest is always held before the
rules are published. At the seniors the handicaps were still discussed
as were the rules for wingloading adjustments. I'm more confused
than before I went there, but the Antares 20E gets an .820 handicap
(it did last week anyway).

See ya, Dave

..820!!?? If it is as good as you claim, it should be around .650
shouldn't it?



:-)

And, by the way, how are the SSA rules handling sailplanes
with electric self launch capablity, since there are
not any IGC flight recorders capable of detecting Antares
20E engine operation?

We did some initial tests with the Volkslogger, and it easily
showed the noise level from self-launch (though its quiet enough
the headset is not really needed). We didn't fool around with
measurement of low power levels yet, but the prop noise is probably
enough at least for the Volkslogger. The 20E is a pusher and it
makes a bit of whop-whop-whop noise, I think from the prop
hitting the wake of the pylon.

Perhaps John Good and Rick Sheppe can comment as they
did the Seniors scoring and looked at this more than I.

Anyway, we'll figure something out...

Please be quiet Larry, I need all the help I can get...

Someone posted an Antares flight on OLC a few days ago, and the prop
operation was pretty obvious in the ENL log.

It is those "low power levels" that are critical in showing a clear
difference (or not)
between engine-on flight and gliding flight with a noisy cockpit.
The latter includes thermalling with cockpit panels open.
See my posting on 16 October 2006 on this subject.
It is worth looking at because it gave a a lot of background
including
the critical cockpit noise cases. Full power is easy, it is running a
quiet engine
at reduced power, say, for level flight, that is the difficult case.
This posting included the following:

"In an Antares flight in August 2006, ENL with engine off was
recorded
in the IGC file from 130 to 448 when cockpit panels were open and
some
sideslip was present. In comparison, in a run with level-flight
engine
power and a well-sealed cockpit, recorded ENL was from 019 to 120 and
about 50 feet was gained. In another August Antares flight, climb
with
engine at about a 200 ft/minute gave ENL between 155 and 398 with an
average of about 280. In this flight, ENL at full power was recorded
between 294 and 769 with an average of about 450. "

IGC has been in correspondence with Lange Flugzeugbau for some time
in order to resolve this problem for flights that are to be validated
to IGC standards of evidence.
That is, FAI badge and diploma flights, world records and competition
flights
that use the criteria of Annex A to the Sporting Code. And any other
flights
that are a National responsibility (BGA, SSA etc) and that use IGC
standards of evidence,
such as some national or regional competitions, national records etc.
In these cases
the National body does not have to stick to the IGC rules and
procedures, but frequently does.

Also, at the IGC Plenary meeting earlier this month, a paper was
passed
on engine recording of motor gliders. This paper was Appendix 2
to the GFAC report to IGC and has been available on the IGC web pages
since January as part of the Plenary agenda. Lange Flugzeugbau was
sent a copy in December 2006.
Here is an extract:

"4. Low noise Motor Gliders. Where the engine system produces low
ENL values
that are difficult to differentiate between power-on and power-off
flight,
an additional system shall be provided in the motor glider concerned
that produces a signal that can be used in the IGC file as an
indication
of forward thrust generated by the engine system
(the RPM three-letter code in the Technical Specification).
This will be subject to GFAC evaluation and decision on the type of
motor glider concerned."

As you might anticipate, correspondence on this is going on right now
between IGC and Lange Flugzeugbau and the results will be announced in
due course.
The issue is not just for the electric versions of the Antares, it
applies to any "quiet" motor
glider and there is at least one other type of electric MG flying
today, understood to be
in prototype form at the moment.

To comfort existing owners of motor gliders, there is no problem with
the cockpit
noise signatures of MGs powered by internal combustion engines
whether they be four-stroke, two-stroke or Wankel (rotary).

That is, other than hearing-loss ;-)

True. Myself, I (almost) always wear a headset when running a Motor
Glider engine in the air.

In the UK Air Force there was a syndrome called "Shackleton Ear" which
was permanent deafness on certain frequencies. The Shack had four
Griffon piston engines (a sort of "double Merlin") and flew maritime
patrol sorties many hours long. People who got "the ear" were
generally those who took off their headsets for long periods of time.
