A hard deck in a 4 mile radius doesn't resolve the issue, only moves the
problem further away from the airport. The only solution is a hard deck
throughout the task area - but wait... what about mountain sites, that's
OK, we will come up with a separate rule for that when we get there .

Cheers,
Luke

PS: I am not advocating a hard deck throughout the task area.. I am
just trying to demonstrate what happens when we move the responsibility
of flight safety from the PIC to the RC...

Personally, I kinda like this 4 mile hard deck idea. It is simple to understand and solves a real problem. The idea of pull ups at 1 mile and 700 ft AGL is a little terrifying. The hard deck would certainly prevent that potential behavior.

On the other hand, (devil's advocate), the high points risk associated with flying out over the hard deck with low energy would result in the same "save it" circling just outside of the 4 miles hard deck "shelf" instead of 1 mile finish circle. The good news is the gliders would be slightly higher at 4 miles.

Would this hard deck be 500 AGL (penalty penalty) or 700AGL (finish height)?

A hard deck within - say - 4 miles from the finish line is a simple alternative. Get below finish height and you're scored as a land-out.



This is indeed a simple and better alternative. It eliminates all this worry about pilots thermaling low to get over the edge, as well as last minute pull ups. (A pull up to get over the hard deck won't work, as you will run out of energy.)



We don't have it, because you see the uproar that a simple finish cylinder is causing. Mention the words "hard deck" -- even just a doughnut at 500 feet AGL, 4 miles around the airport -- and there will be RAS apoplexy. I brought it up once, and the rest of the RC pointed out wisely that if I wanted to go get tarred and feathered that was fine, but they weren't going to join me.



Don't do big pull ups at the finish!



Once, approaching Hobbs at about 70 knots -- I was on a pretty marginal glide to the cylinder -- about 1.1 miles out a glider rose up right in front of me. He had passed me below at high speed, somehow missed the glider above him (me). Staring at the airport on final glide is common. At the moment of the pull up, I couldn't see him -- I'm above -- and he couldn't see me -- now behind his tail.



When you do a big pull up, there is no way to see who is above and behind you!
