My KLN 94 has a POH supplement that states the Pilots Guide is
incorporated by reference. The KLN94 Pilots Guide Part Number
006-18207-0000 page 2-4 states "Note: By FAA regulation, you are
required to have a current navigation database in order to use the KLN
94 for a non-precision approach."


OK there's no argument on that point. The difference we are having is a
terminal/enroute box that you don't shoot approaches with, such as the
GX55 in my plane. It can legally substitute for ADF/DME but some folks
are saying that the database is required to be current. My box is one
that says the user must verify waypoints if the database is expired.

Newps, this is a great question. At work we are allowed to MEL the
database provided we verify the waypoints (And our box is certified
for RNP) , but for part 91, I doubt you have an MEL. This creates a
grey area and I dont think the feds would give you a consistent
answer. If your manual says it is OK just do it. In the older Boeings
there was a requierment for one of the pilots to be in raw data by the
FAF so we would dial in the NDB but of course we used the box to fly
the course. Nobody could argue with that because we were legal and
safe. So just dial in the NDB and use the box for a "Backup" and you
will be fine.

Dial in the NDB? That's freakin' hillarious. Even if the FAA stance
was the database has to be current I don't mind bustin' that rule.
That's just dumb.
