One example of the aircraft specific section is the Cessna 172 Skyhawk fitted with a G1000. In other words, a unique bit of avionics in a plane.
Set Filter to None and type PFD in the search bar. This is what you get:
Every G1000 PFD control.
So you could bind spare joystick buttons to change the PFD baro setting.
With a bit of creativity you could bind F1 to F12 on the keyboard to be the G1000 menu buttons on the PFD.
