November 22, 20187 yr Hi, I'm not sure if its to the GTN 750 related to this issue, but the CDI goes crazy every time autopilot NAV option is enable and GPS. On the GTN 750 CDI is enable and follows the flight plan, but the HSI is rolling ln every direction with no control. Cheers Jaime Monterrey, Mexico
November 22, 20187 yr Hi Jaime, what do you mean with "rolling"? Is it the HSI course rotating around randomly, or, the CDI bar deviation going from left to right erratically?

November 22, 20187 yr Thank you, this explains better! I don't think this is a bug in our GTN, the code driving the HSI course has been the same since the first version. I'd suspect they've coded their EFIS in a way which conflicts, probably because they have an auto-slew feature, and our GTN too. I'd suggest you review the GTN settings and disable "Connect HSI/CRS output".

November 22, 20187 yr Set GPS drives CRS to false and works but have to select coarse manually. Was working okay before last update, now when I select direct to a airport the helicopter swings left and right chasing the coarse needle in true, large swings of plus 90 degrees.

Are you sure it is not a side-effect of updating X-Plane 'beta' versions (if this applies to you)? Also, which trainer do you run, is it the latest 6.50.1 or any previous one?
November 22, 20187 yr Author I have v 6.50. It is normal that the trainer is off? Maybe I'm missing something here. Jaime

November 22, 20187 yr Author Just now, RXP said: I'm sorry but I don't understand, your video shows it is on isn't it? I'm referring to the Garmin trainer directly. I clicked to the power on button and appears in black screen.
November 22, 20187 yr It is possible, nevertheless, as long as it works under our control, this is not an issue! Otherwise, you might want to try out their latest version GTN Trainer 6.50.1 which our latest update v2.5.8 is compatible with. Edited November 22, 20187 yr by RXP
November 23, 20187 yr A bit more testing. As soon as I set connect HSI to CRS the coarse need in HSI starts swinging around as the video above, Tried with the GNS530 and that works fine. It is the GTN 650/750 that is having the problem.
