Hello folks,

In P2ATC flight plan I see TRK and next to it what I assume is the (magnetic?) heading in degrees for that leg of the route. In my aircraft the heading value that is presented on the screen that the aircraft is locked onto  is always 2-3 degrees different. 

Is there a reason they are not the same?

Would this also explain why I get route drift over time?

I export my P2ATC flight plan to my FMC, so I assumed they would show the same?

Any advice would be appreciated. Thanks..

The track is the desired magnetic ground track.

Your autopilot must apply a heading correction for wind and so unless there is no wind or a direct head/tail wind, there will always be a difference between the desired Track and the heading flown.
