Hello engineer

I used AirTrack to connect to P3D, but found that many functions are unavailable. At present, I can only see changes in airspeed, altitude, and heading. The other functions do not seem to be available.
I am not good at speaking English.sorry

Running environment
system：windows10
simulation：Prepar3D_v4.5.13
aircraft：PMDG737NGXu

Hello,

I'm afraid P3D support is very limited :(

It should however show all those things plus the attitude on the PFD and the compass, as well as your position in the Navigation Display.

The flight plan doesn't currently work so you need to configure AirTrack to use standalone flight plans. Do to this go to the Settings App (the one from Apple) of your phone or iPad, scroll down to AirTrack and enable standalone mode on AirTrack.

This will make the flight plan work locally in AirTrack only (and the ones you create on the web site using an Air Account) but will make them independent from P3D, so you need to create the same flight plan on both.

It will then be shown on the ND and you will see your plane flying along it.

sorry for the limitations,
