How do I setup the Nav instruments for an ILS approach or use the Autopilot?
key on your keyboard will cycle you through a number of pop up panels. One of these panels is the radio stack. It uses a mouse click interface to tune the radios and activate the autopilot. There are key commands for many of the radio operations. They are listed in the ProTrainer User Guide that is installed with ProTrainer and in the Key Commands dialog in the Help menu.
