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).

Ian,

Most aircraft in the US use the Nautical System, ie Commericial,
Military and most private aircraft. 1 Nautical mile = 1 second of
latitude, 60 nautical miles = 1 degree of latitude.

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

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

It's defined as 5280 "survey feet", and the survey foot is in turn defined
as 1200/3937 meters.

The term "Mile" is ambiguous. There are lots of different "miles",
for instance there are theoretically an infinite number

The statute mile may be weird and inconvenient, but it's no more imprecise
than the kilometer.
