July 5 was a good day for FAI triangles**. Thanks for towing, Rick!
Dan &
Greg join the New England 500K FAI triangle club, which I reckon numbers about 8 pilots and fewer than 20 such flights. These guys have it figured out. Superb flying. Well done!
Evan had a good day, as well. Most of the flight was too involved for sight seeing, but the Green Mtns offered "hero conditions" that allowed a moment of relaxation and a few quick photos.

**For courses under 750km, the definition of an FAI triangle is a course defined by three waypoints, with the shortest of three legs being at least 28% of the total distance. The start & finish points must be co-located, and may be either on one leg or at a vertex. If more than 750K, the definition isn't quite that restrictive, but nothing we've needed to worry about in New England. Yet.

What is an "FAI Triangle?"
Making the start/end point a vertex of the triangle forces the other two vertices to be farther from "home", thus a bigger challenge - especially with the added requirement of per-declaring the turnpoints. My personal challenge for years has been such a 300km triangle. I managed that once, 20 years ago. Still trying for the same again, with shorter wings this time.
Hi Moshe. That doesn't make sense. There is no requirement to start/finish at a vertex of the triangle in any Sporting Code achievement, as far as I know.
A FAI Triangle is a right triangle. Fly the right triangle and you win.
Don't be obtuse, Gregg.
What happens if you declare a 751 km triangle that barely satisfies the 25% rule, but you claim the two turnpoints by flying just within the 500m circles?
Your credited distance is reduced to 749 km. Is that still a legal FAI triangle?
Triangle Lines Matter
Rick: like I said, it's my personal challenge. Nothing official with the FAI or any other group. And when I say "pre-declare" I mean to myself. And perhaps to my buddies. It's all for fun.
I guess this one doesn't count, since the start/end point is in the middle of a leg. Oh well.
