There is a big difference. An NDB station is just an antenna mast with a very simple transmitter. No particular siting requirements, the monitor needs only check that the station is transmitting at all. A VOR station is an entirely different beast with a much more complex antenna, seating requirement, transmitter and monitor.
This thread is about dual NDB approaches.
Those were always rare.
Great post by vic – thanks!
I don’t know whether this qualifies as dual NDB approach.
Bern used to have one. It even used 3 NDB’s if you count the GA fix. Shupberg, Muri and Berne. Flew it many times in the Seneca when doing my IR at the time.
