But from the manufacturor's website:
http://www.rigginginnovations.com/products/aviator.htm

"The 246 and 280 sq ft canopies have a unique modulated control
system, which allows for their use by aircrew personnel with minimal
additional training required over and above what they receive on
current round parachute systems."

That doesn't sound like a big barrier to use.

The only real barrier (IMHO) is the price difference.
