What data is responsible for the fact that the aircraft is within the coverage area of the glide path beam? At this moment, the “GS” icon lights up on the display (if we take the bonanza v35b as an example). I need to configure the light indication on the joystick.
How about
- A:AUTOPILOT GLIDESLOPE ACTIVE, bool
You can also use
- A:AUTOPILOT GLIDESLOPE ARM, bool
to indicate that the GS is armed, but not active
=======================
- A:NAV GS FLAG, bool
may be part of what you are looking for
