The questions on FLARM are copied below. Make what you can out of them....

And, perhaps most telling of all 2.7,

Do you think gaggling and leeching are serious problems, and the RC should consider other rules changes (not Flarm-related) to reduce their prevalence? Develop Rules 11%. No 85%.

Remember, this stealth mode business is all a complex undertaking to reduce leeching; the ability of one pilot to gain by following others. There are lots of ways to leech, and lots of rules to stop it, especially in the starts.

I actually thought the numbers would be much greater on this. But the verdict is loud and clear. Gaggling and leeching in US contests are not perceived to be a serious problem by 85% of the pilots.

Where is the fire?
