Delore & Fossett soar 2190 km

The challenge prize for the first straight line flight of 2000km, was put up
by Dr. Joachim Kuettner, won by Ohlmann, and presented at the 2004 SSA
Convention in Atlanta. Even broad very wave bands, and the corresponding
jets, are generally far too narrow for completing such a flight, hence the
challenge, how to get the additional 500km+. It's taken several years of
research and attempts to complete these flights in Argentina. Are
2500-3000km straight-line flights possible? Downwind?

Excuse my ignorance, but what is so special about flying in a straight
line
instead of doing a few turns along the way? - Oscar

How do you define `straight'?

Doesn't matter how I define straight, but how the FAI defines it for a
record. It's the distance between the start and finish, with no turnpoints.

See the sporting code http://www.fai.org/sporting_code/sc3.pdf
Free distance and straight distance to a goal are the only relevant
categories.

If you deviate off track, you'll gain no extra distance. If you wander much
further than 15 degrees off track on a goal flight, you reduce the chances
of making the distance in available daylight. For free distance, wandering
into the best lift may be optimal up to say 30 degrees if you aren't going
to reverse back to the original track and just accept a new finish.

Since the best wave conditions rarely exceed 1500km in span, downwind
flights transiting several mountain ranges may offer the better opportunity
of completing a downwind wave flight of 2500km or more. I believe someone
once surmised that when the jet developed a large deflection over the
northwest United States that an early departure into wave from Washington
State or British Columbia towards New Mexico into Texas for about 2500km
straight distance might be possible. However, heading south and east limits
available daylight and great wave conditions don't often happen during the
longer days in North America.

But that's old stuff now. He did 3000 k and a bit,
last year or year before.

No it wasn't, and his 3000k+ flight in a Nimbus 4 a year or two
ago wasn't either.

Another possible difference: Klaus flew a motorglider. The
OT doesn't say if the ASH25 in question was a pure glider.
If it was they'd be classed as different records.

The ASH 25 M used by Delore/Fossett is a motorglider, but it doesn't
matter, as the FAI combined glider and motorglider categories several
years ago.

It's the FAI great circle ie: shortest distance in a straight line )
distance between the start and finish, with no turnpoints.
