GPS as ADF substitute
I fly a Warrior with average Navaids (VOR/ILS/COM/ADF), but the ADF is u/s and the group isn't motivated to produce the money to fix it.
Having used the ADF (different PA28) for my IMC training, I miss it now.
I have a GPS III Pilot, which I use purely as a secondary navaid, and wondered if it is considered acceptable to use this as a substitute ADF?
Also, I haven't done any instrument landings in the 9 months since getting the IMC, but wanted to know your views on using the GPS as an ADF substitute on NDB holds? (I don't plan to try any IAs without refresher training!)
