Camo,
Um... define "dot range"... who's dot range?
These are the details that can cause problems.
It would be best to either forget about altitude limits, or do as was suggested in another thread, pick a quadrant or two and call those as "open". IE line everybody up in the adjecent quadrants at 15k, then call "go" and as soon as you cross into the square anything goes.
The best idea IMHO is to start everybody on the ground... no limits. Everybody must be OTR with film running when GO is called. After that, those that survive win. You can disable re-planes and forbid folks to exit a certain area. I would also set a time limit on it... a far-out one, but something to keep folks from trying the "take a pony with full fuel and run until they are all out of gas" trick.
How's this sound?:
Both teams form up OTR at designated field.
All pilots must turn film on before "roll" is called.
All pilots must stay within a specified area.
Replanes will not be allowed.
Time limit of 30 minutes.
Anybody see a way to "game" this? I can see two possible ways. Fuel and Ack.
Hopefully the time limit will discourage the fuel game. The time could be changed if desired.
One side could TRY and hug ack I guess... but I don't think this would be a great tactic. If you dive down low enough to be in ack, you are in serious toejam anyway and they will eventually get you.
