GPS Use

Anybody have the link to the FAR that states what the requirements are
for IFR approved GPS's and the database currency for those units.

Maybe AIM 1-1-19.4.f will help.

And the GPS unit's AOM or Pilots Guide.

I need the FAR or Advisory Circular that covers this. The AIM is
actually the root of the problem. I believe it to be wrong and isn't
the legal basis anyways.

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."

Since the POH is required to be adhered to, and the Pilot's Guide is
incorporated by reference, it would seem to be the legal basis
mandataing a current database for any non-ILS approach with that unit.

It would have been nice of them to footnote what FAA regulation
they're referring to when they say that one requires a current
navigation database. Perhaps emailing Bendix/King and enquiring would
get them to send you the reference?

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.

Our's come with expiry dates on the database renewals themselves. When you
are within those dates, you're legal and hopefully safe, if you've read the
notams, of course.

AC90-100a Para 10.a.3
(3) The onboard navigation data must be current and appropriate for the
region of intended operation and must include the navigation aids,
waypoints, and relevant coded terminal airspace procedures for the
departure, arrival, and alternate airfields. RNAV STAR procedures may be
designed using multiple runway transitions. Operators not having this
functionality shall provide an acceptable alternative means (for example, a
tailored navigation data base). If no equivalent means are available to fly
the charted RNAV procedure containing multiple runway transitions, operators
will not file or accept clearance for these procedures.
