Just use the 6DOF, if you dont have TIR, use the mouse version to look over the nose. That's what I did and had no problems navigating the airfield... then again, I started next to 2 AI P51's already line up to take off from the airfield so I just followed them.
Right, now I'm off to re-install IL2 1946. It was so darn messy that I though maybe better get rid of it and do it again.
