Can anyone assist me on an explination on why the heading bug does not line up ..  with actual aircrafts heading attached image shows what happens.

 

 

Thanks... how do you post an image of the problem ...i have used jpeg and it says not allowed to use that file extension ..

That's just the "track up" option. The way you're traveling is on top on the ND. Due to crosswinds, that will create a difference between heading and track.

 

You can change that in the options, I believe. I think AirTran used Heading Up, but most airlines use Track Up.

You will find the heading that you are looking for on the bottom of the PFD

Thanks for your advice..
