Navigationsdrehscheibe/compass swing

[Wybe Buising]

Hello all,

can anyone fill in the gaps in my knowledge on the above subject? I am very curious to know what kind of Navigationsdrehscheibe types were in use at Luftwaffe airfields. I know of one type (the ND 12/30 Ae) which was in use at the Gilze Rijen Airfield here in Holland and survived the war. Other airfields also had one.

Were all these Navigationsscheiben of the same type or did there also existed smaller Scheibes for smaller airplanes?

Last question: can anyone explain to me the exact procedure of calibrating an airplane on such a Scheibe. I know there is a manual on the ND12/30AE but don't have it (RLM LD7 IVB).

Best Regards

Wybe
