Hi,
What you are looking at is a bug in FSX.
In order to create a runway that AI aircraft can use it has to be two things, solid and flat. The aircraft contact points also have to be set correctly so they show spray as an effect and not sparks. This is the reason for supplying a specially made AI aircraft.
The concrete runway is in name only to tell FSX that it is solid. Due to its width dimension it is actually below the minimum scale that FSX will render. In consequence you have a workaround that says "you can land on a solid surface but I'm not going to show it to you because its too small".
In respect of the headings you can have North/South and it will show exactly as created or even East/West. Change it to a number and it will be fine but, NW/SE or NE/SW although accurate will display incorrectly.
You have a choice, use North/South and know that it looks right but is in fact wrong or have it 50% right knowing its a bug and you will have to use your imagination for the other 50%.
Iain will be making a North/South version available shortly, however, if whilst lining up to land you notice the compass doesn't show North/South you will just have to live with it, its FSX and its far from perfect.
