WGC 2008 TP radius?

Anyone know what is the TP radius for assigned speed (racing) tasks at
Lusse? Is it posted on the official site somewhere?

I would have to assume 500m radius

The rules for World Championships are in Annex A to the Sporting
Code,
see http://www.fai.org/gliding/sporting_code/sc3a

Many other competitions also use these rules, to save the organisers
making separate rules.

On TP radius, Annex A says:

7.5 TURN POINTS AND ASSIGNED AREAS
7.5.1 The Observation Zone for a GNSS Turn Point shall be a cylinder
of radius 0.5 km, centered on the turn point.

Thanks to both of you. We use 0.25 statute mile in US and that is a
smaller radius.

John Good's blog now has the explanation I, and I'm sure many other US
pilots, had been waiting for.

0.5sm is of course larger than 0.5Km.

Tough way to lose points.

US turnpoint radius for MAT and AST is now 1 mile which is intended to
reduce meaningless penalties for small misses and slightly spread the
fleet at the turn for , hopefully, enhanced safety.

Oops. I forgot that change, probably because I haven't flown a
contest for over a year. Brain reverted to old memories. Thanks for
the correction.

Question:

What is a US Statute Mile in terms of feet or metres?
The term "Mile" is ambiguous. There are lots of different "miles",
for instance there are theoretically an infinite number
of different lengths of Nautical Mile ....

But only one definition of a Metre, and therefore a Kilometre.

This is one reason why IGC has always used metric units
for International definitions (Badge distances, for instance),
and science uses the SI system which is basically metric
(I stand by to be corrected on this statement).

Hi Ian,

The term "Statute" clarifies the type of "miles". It is different from a
nautical mile. US Contests use Statute Miles because Americans are used to
driving distances in statute miles. You can find conversions he

Like many Americans - I prefer the metric system as well. Much of my
college engineering education was done using metric units.

Ian,

Paul didn't really answer your question. A Statute Mile in the USA is
defined as 5,280 feet. The Nautical Mile length in feet isn't as
clear, as you point out. I've seen 6,080 feet, 6,076 feet and 6000
feet.
