No brainer. Yes. But hardly necessary, as I think we've all got the

John,

What rule would you propose? *How will that rule take account of the
non zero probability that a FLARM will fail.

As you said the rule is hardly necessary since we all got the message.

A world contest can say "you have to have a flarm" the same way they
can say "you have to have a parachute" and "you can't have a turn and
bank." It's part of the scrutineering. I don't think there will be a
huge problem of people getting a flarm or parachute to show organizers
and then deliberately removing them for flight. There is the minor
issue of people turning flarm off if they think someone might follow
them, but that's a separate issue.

I do not favor mandatory flarm for US contests BTW. But it makes much
more sense for world events. People are putting a lot (a LOT) of money
already into world competition, so extra cost is really not an issue;
they have 150 gliders not the 20 that fill a typical US contest, and
they have tasks and rules that encourage mass gaggling. 95% already
have flarm.
