Interested in your thoughts about the validity during an instrument rating test, of using LNAV for flying an NDB approach or over-laying a localiser track that happens to coincide with an NDB inbound course and using VOR/LOC mode to maintain the NDB track.
While this combination makes the tracking of the NDB on autopilot relatively easy especially with FD operation, some may argue it doesn't really test the candidate's skill at using the ADF needles for tracking. In other words the NDB approach using LNAV cannot be honestly called a test of pilot competency at flying an NDB approach?
As an instrument rating examiner would you be happy to tick off the box that the candidate has demonstrated competency to your satisfaction that he can fly an accurate NDB approach?
