That's OK for practical use; you are just illegal for IFR in CAS (no known enforcement in the UK, but the UK is not the only country that requires the carriage of an ADF; do a random scan of the AIPs) and you have to fly NDB approaches using the OBS mode :)

ADF
 

The "Nav" man at Oxford always said it was an early version of "Weather Warning" as it always pointed to the nearest thunder storm !!!.
Myself i always considered it to be a cunning scheme hatched up with the CAA and training schools to double the numbers of hours required to get an IR.

If I'm not totally mistaken, the bench upon which the ADF sits, is in the hold at Cranfield for a procedural approach....:8

Presumably the CAA are changing their stance on ADF. In UK NDBs are being shut down, probably partly because no-one wants to pay for their maintenance. LIC has gone earlier this year and has been replaced by a waypoint known as "PEDIG" (although it was still radiating after it was NOTAM'd as withdrawn).

..........and i thought mine was just for giving you flight timing.
