Simvar. Aircraft in the glideslope zone

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
