Thanks to pcx and CMH - yeah, long story but don't have VOR... And yep, you answered my other outstanding question re getting VOR "added" - needs to be in an actual aircraft, not the overseas sim I'm using...
As I alluded to in a personal response, the situation is a bit funny.
I mean, if you can demonstrate a holding pattern, approach and MAPP on a dodgy, fixed card ADF and you've demonstrated an ILS approach, then surely that would cut the mustard for a VOR, which of course would be much easier? To my mind, the NDB is significantly more difficult, yet effectively the same style of approach and method of flying (if you're using an RMI, it's exactly the same...) But, I understand that would probably just add further confusion.
