So not sure exactly why it's flagged VFR Only but a flight school I'm working with has a G400 (it may even be the WAAS variant G400W, not 100% sure) in their aircraft that is placarded VFR Only. My guess is that it is mounted on the right side of the panel and is not in the immediate reach or view of the pilot in the left seat. The database is also long expired but I know the FAA permits the usage of an expired database for IFR flight during the enroute portions of flight and also permits the usage of an expired database for approaches provided the approach has not changed since the database was updated or the pilot has verified the approach details but I digress. My question today is, is it legal to use a GPS placarded VFR to do a practice GPS approach in VFR conditions? I haven't found any reason that it could not given that you are still in VFR conditions and are flying the indicated approach with a VFR safety pilot in VFR conditions as a VFR flight while you personally are under the hood in simulated instrument conditions.
