Hello, Looking for the parameters to control the external HUD , Having issues
with Airspeed indicator and engine N1 display (turbine engine)
Hello @MarwanGharib If you have a turbine, you want to set the
vcockpit_hud to 1 in your cockpit.cfg file. For now, we only have
either a piston-mechanical or a turbine-efis HUD design. So you can’t use the
mechanical design for an aircraft equipped with turbines. Then, you can adjust
the appropriate section of the cockpit.cfg to adjust your color ranges.
The REFERENCE SPEEDS section of the flight_model.cfg will also
influence the speed tape. Hope this helps. Regards, Sylvain
Hi Sylvain, Thanks for this, maybe hood to add this to the common issues and
workarounds?

Just FYI, you can actually add it to the article yourself; it functions like a
wiki page, anyone can edit.
