IFR GNS 430 with expired database

What about using it for locating missed approach holding points (a-la
NDB or DME substitution)? Since the database is out of date, you
can't use it for approaches, even non-GPS.

It depends on the HP - often it's a return to the OM using a
backcourse, or a nearby VOR, or intersection of 2 VOR radials. None
of these requires the database. Even an NDB would work if you have
ADF on board

From the Garmin manual: ( I have similar verbiage in my AFM
supplement. Yours could conceivably differ.)

"You may file your flightplan as /G if your GNS430 is a certified A1
(approach approved) or A2 (enroute and terminal only) installation. If
you are flying enroute, you may file /G with an expired database only
after you have verified all route waypoints. Non-precision approaches
may not be flown with an expired database. See your approved Airplane
Flight Manual for more information."

So to comment on an earlier point, you can still file /G, even with
an expired database, under the restrictions pointed out earlier. Note
you can file /G with a C129(A2) installation for which approaches are
never approved!

It's hard to imagine anyone thinking an expired GPS database would
prevent you from using the *other* navigational equipment in your
airplane - like an ADF or the independent VOR/ILS in the 430.

I don't think anyone does, except in the cases where you are required
to substitute because you don't have an ADF or DME and the precision
or VOR/DME style approach requires the GPS be used as a substitute for
ADF or DME. AIUI at that point you have to have the real equipment or
a current database.

I have been told that you can look at the revision date on a CURRENT
approach plate (or look it up on the Internet). They are given in year, day
of year format at the bottom of the NACO charts. If your database in the
plane is that date or newer, then the database is current for that specific
approach.

If they haven't revised the approach since your database, it has the
appropriate information (for reviewed and date matched approaches only). I
know the AFM supplement is controlling but I think that is what it says in
mine.

I have been told that it is illegal to fly IFR in an aircraft that has an
operating IFR rated GNS 430, whose database is out of date, =even= if it is
placarded INOP, placed in the OFF position, and the airplane, even without
the 430, is otherwise legal for IFR.

True?

Jose, let me repeat what I have said many times: When you are told something
like this, ask for documentation. There are far too many pilots who are
willing to swallow a story whole without question, and far too many
instructors who simply pass on what they have been told by someone else.

Bob and Jose,

Here is the documentation!
