Guys,
I use Game Commander to achieve voice control over PFE.
At the start of my session, I say "Clearance, Speedbird 3 5 3, at the gate, ready to copy IFR Clearance". I have already programmed GC to pass the "0" key to PFE whenever I say this, so PFE immediatley responds with " Roger, Speedbird 3 5 3, Cleared as Filed ,....... blah, blah, blah".
You can programme GC to transmit all of the various PFE keys, depending on what you say. You can even transnmit the same key, via different verbal instructions, thereby giving a lot of variation to what you say. GC can also be programmed to only pass what you say by pressing a joystick key ( ie a Push to Talk key).
If you then switch off the PFE screen messages, you get a very realistic ( I'm not a RW pilot, mind you) experience.
