Is it using the ‘C++environment’?

If what you’re asking is, does building an AIR application for any supported AIR target compile it into C++, the answer is no. It’s compiled into byte code, to be run within the ActionScript virtual machine (AVM2).

The iOS target is uniquely different, and it’s ultimately compiled into native assembly, so no virtual machine is used there.
