The game has a problem with interaction of wind and planes on ground, why the plane drift before start the engine.
A 3 m/s wind turn the plane face the wind, a 9 m/s prevents open the Bf 109 cockpit pointed for eh wind...
In Spit, Hurri and Blenheim is need adjust the Directional Gyro with the Magnetic Compass reading at mission start* and after make G maneuvers.
http://simhq.com/forum/ubbthreads.php/topics/3436574/Navigation_tips.#Post3436574* In air start - single player - the Directional Gyro is automatically set with Compass.
Problems: is not modeled the
"Lubber Line" (reference line) in P-8 compass to read/set the heading, so is need use the digital info on "Info Windows" - see in the link.
Is not possible (at
least in simple way) make a shortcut to camera focus on compass, is need use cockpit 6DOF with mouse - press F10, then press mouse middle and right buttons, move mouse - or use TrackIR.
