Teaching pilots in the lower 48, where the FAA is ripping out ADFs all over the place, I don't spend any time teaching ADF. I noticed and discussed with the local designated pilot examiner, that the FAA written STILL contains ADF questions. He indicated that he never asks any candidates about failed ADF questions. He also indicated that the commercial glider written also contains ADF questions. Does anyone address this another way than just ignoring it and apologizing to the student for the FAA's ineptness?
I explain that the older airplanes that have ADFs have 2 functions, Country Music and Talk Radio.
