Quite so, Dan!
The folk I work with now aren't even allowed to fly non-HSI approaches! So if the aid cannot be selected to the HSI, you cannot fly the approach!!
All those NDB, TACAN and the odd VOR approach we used to fly on the basic RMI would be forbidden....
Watching the aeroplane fly its approaches, automatic level offs etc made me realise how prehistoric the old Vickers FunBus really is! But the A320/A330 are even better...
