| | Guest | 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?

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

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).

| | Guest | WGC 2008 TP radius? 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.

1/2 kilometer. Unfortunately, Karl Stiedieck had 1/2 mile mistakenly
in his SN10, was not scored for a turnpoint he made, thus scored as
landed out several days ago - ouch
