Whether or not the Apollo units are a good idea or not is not something
I
will address. Don't forget that they are essentially "orphaned" units.
Also, to be legal, there may be instances where you need to have the ADF
equipment on board.


I thought that an IFR GPS was a legal substitute for an ADF in ALL

What do you mean by "ALL"? Some ILS approaches still require an ADF (i.e.,
BHB ILS 22).
