competition finishes

More like laughable considering I do not ever recall Derek winning a comp
day!

Our Australian comp rules and CAR's have accommodation for low finishes and
the GFA now requires a log book endorsement to do so.

A logbook endorsement sounds logical. Who in Australia are authorized
to do them?

I remember when I started racing a few years ago having to figure it
out for myself. Of course, I picked the brains of the pilots I was
racing with, but outside of that, the topic was not addressed (in a
how-to fashion) in any of the stack of racing-related reading
materials I assembled, which I found curious. It seemed to be a
sanctioned activity, after all.

I've always viewed fast, low finishes them as something of a penalty
(speaking in a racing context, of course). If you have the energy to
spend the last few miles of your last leg in a highly inefficient part
of the polar, it means you accumulated too much energy before starting
your final glide, and you lose more from that than you gain with a low
finish.

But they sure are fun to watch. I will never forget the sight of a 15M
glass slipper doing a worm burner finish at Seminole Lakes in November
2003 when I was a pre-solo student stick. He went by at mach 2, a
meter off the grass, from one length of the field to the other, and I
never heard a whisper, and he was maybe 100 meters away. I was amazed,
and I was hooked.

16. FINISH PROCEDU The finish line shall be the perimeter of a circle of
1.5km in radius

centred on the Aerodrome finish co-ordinates. Finishes are to be in
accordance with

CAO 95.4 (ie not below 500 feet AGL) until within 5 kilometres of the finish
line and must clear all

obstacles by at least 50 feet. Pilots should finish from the direction of
the last turnpoint or control

point.

I read the linked documents but could not find a reference to how a
pilot qualifies for the low level enforsement. Does it require
specific training, or is it sufficient to have been doing it for years
without mishap.

http://www.gfa.org.au/Docs/ops/opregs.pdf links to the right have the info.

Specific training or demonstration would qualify as long as the instructor
was certified to do it.

Sure - it's more efficient to finish at your interthermal speed but
the penalty for finding yourself too low and topping off in a garbage
thermal is far worse that keeping a safety margin and burning it at
the end. How much safety margin may depend on pilot experience, the
terrain close to the airport, and the expectation of lift/sink.

In USA it was common to finish at 50ft min through the line and then
pull up and fly a circuit to land. It seems other countries are flying
a worm burner to a straight in landing. That seems to give less
options if the runway is congested.
