Most folks use Rocksim Pro to do the 3 sigma analysis they hand that
over to the FAA and the use TAOS. One fella on the list here created
SPLASH and he might be reachable. I have not tried to pass a SPLASH
analysis to the FAA yet so I'm not sure if they will accept it. However
if they run TAOS on it anyway I think SPLASH may be acceptable if it has
enough data for them to do their analysis.
RS Pro cost a grand and is going to be the cheapest route as far as I
know other than SPLASH. You can get TAOS for free if you have a CAGE
code that might require you to have TAOS for a government contract.
Some of the requirements and that CAGE code stuff has changed since I
last worked on it so- But that direction is an option.
Missile DATCOM was another useful program that was in circulation at
one time but I don't think it's enough for the FAA alone.
Far as I know- There is another solution but I've forgotten the name of
it as it cost 20 grand or so.
