Huge chasms are present between what is required by law and what is practically sensible to have. Interestingly our American cousins have done away with ADF and DME as required equipment for an IFR fit.
The woeful inaccuracy of ADF/NDB compared with GPS fully justifies this IMHO.
Hopefully the advent of GPS approaches (which they have had in the US for ages and are amazed that we have not) will see the antiquated NDB/ADF system being phased out.
DME still has a place, but ADF is a complete waste of space IMHO.
