Hi, I had a similar problem recently and solved it by updating not only the graphic cards drivers but also all the Windows updates as well. A very frustrating process but got there in the end.

A useful tip to line-up is to visualise the runway as a pendulum pivoted at its far end. As you approach the runway, if the near end is pointing to the left, then you need to alter your course to the left and vice-versa. This works with any simulator as well as in the real world. This will only give you lateral correction but the vertical is usually easier to eyeball.

Try looking in the Prepar3d v4.2 for a folder named "delete generated files". Open this then click on "run as administrator"". I had a vey similar problem and this appears to have solved it.

If you follow the above link the problem should be resolved.

Ok, hope someone else will come along.

Hi, once you have uninstalled both programs, look in c drive for a flight 1 folder containing a file "gtn 750p3d.lic" and delete it. This has solved reinstall problems in the past.

Hi, you may need to uninstall both the GTN 750 and the Garmin Trainer then download and install the latest versions on both. I had to do this recently to correct a problem. All seems to be working well now.

I have been using Horizon Generation X photo scenery in Prepar3d very successfully for some time now. Recently however, Prepar3d seems to be deleting it automatically. I can load the scenery and it will display correctly the first time I run Prepar3d. After that, when I load the simulator, I get error messages saying the scenery cannot be found, and also the scenery sequencing is corrupt and will try to repair this. When the simulator eventually loads, it is back to default scenery. This happens regardless if I use the migration tool or install directly. I have tried to repair the P3d installation and also tried a fresh download. This has only been happening recently and I am at a loss as to what is causing the problem. Any help would be much appreciated.

I had a similar issue recently. I resolved it by uninstalling both the GTN 750 and the Garmin trainer and downloaded new versions even though I had used the update tool. All working fine now. Also worth deleting any entries relating to either program prior to a re-install as JYW suggests.

I replaced my old CH pedals with a new set of CH pedals!

It's possible you have the elevator trim assigned to more than one device. This will give this effect.

Thanks very much.

Which aircraft is this?

I had this problem some time ago, solved it by changing the wireless router! Whether there was a tick box not set correctly, I don't know, but this did solve the problem after a lot of frustration.

Good, keep me posted.
