To see cockpit alignment, download this aircraft and put it on Yeager - Kinderflueg2 - It shows the offset nicely.

@Fergitheflamingo my old tablet lagged out after loading it: )
I know you wanted this on both runways... And there are two answers for that.
1) At Yeager, there are three tie-down spots (parking spots) on the apron, between the runways. If you load a car into Yeager and drive it to the center spot (lining it up carefully with the runways) you can save that as a starting position for the game. Go to the Menu, then Locations. At the bottom of the locations sub menu is a button to save the current location. Just save and name the location, then load the aircraft to that location.
2) For better runway alignment, the game will align the primary cockpit with the runway. If your primary cockpit is off center, then it will load the aircraft off center to keep the cockpit centered. Just make sure to balance the weight. Another cockpit to the other side would do nicely. You need balance, because this is a flying wing. Any imbalance will cause a roll. Any attempt to correct that roll, using the ailerons, will start a flat spin. But, flat spin in flying wings is a whole other subject.

Now this... should be called Albatros.
