Hey everyone,

I’m a CFI/CFII recently got in an airplane equipped with a GNC 355 and only one NAV/CDI source (no second CDI/backup NAV).

I’m curious how other instructors are teaching:

Getting everything properly set up prior to the approach (freqs, course, CDI source, etc.)

Managing the workload during the transition from GPS → VLOC (especially on ILS/LOC approaches)

My biggest question is how to maintain positive course guidance while switching between GPS/VLOC. And what do DPEs want to see.

Thanks everyone.
