Example Glens Falls, NY KGFL ILS RWY 1 approach. On face of approach plate "ADF REQUIRED". ADF & OM are together which is a LOM. Can a GPS legally be used instead of ADF if aircraft is not ADF equipped?
ADF would be used on the missed, can GPS be used?
One instructor says yes, another no.
Tried logging in to AOPA forums and asking, got new password & login name and still can't get on the forums.
Thanx in advance
