Hello.

This afternoon i've started a flight with the Flysimware Learjet 35, wich i have with the GTN750. Some months ago i flew this same plane with the GTN without any hitch, but today the plane was unable to follow the magenta line, even when the autopilot was on and nav mode as well. I've popped up the option menu of the GTN in case it wasn't coupled with the automatic pilot, and then realized that all options in the panel instrument menu except "master device" and "connect GPS to HSI" were grayed out and with red locks next to them. A red text says that the red locks are "locked device settings", and i can´t remove those locks by any means. "connect GPS to autopilot" is one of those locked options, and that i guess is the reason why the plane is unable to fly in nav mode.

How can i get rid of those locks? and why are there those locks to start with? I´ve had the GNS 530, 430 and GTN750 for a long time and i´ve never met those till now. Any hint about how to regain control of those locked options will be welcome. I´ve tried reinstalling both the GTN and the plane but nothing has changed so far 😥

This is what i'm seeing in the options menu of my GTN

Well, it seems the GTN and the plane work well after all. I was a bit rusty it seems and forgot certain switch necessary for the AP to activate 😳. Just did a short flight and everything worked allright.

This is a long way since the days of FS4! Our hobby is getting so close to the real world we'd probably need a type qualification in the future!

Do you mind sharing which A/P switch configuration was necessary? This will certainly help others in the future.
