Subject: | Re: Equipping experimental for IFR |
Ok, thanks. In the case of the pitot static and transponder, they get tested every
24 months. Is this test different for VFR versus IFR?
For the Garmin 430W, I've heard that this requires a ground test and flight test?
Is this something that needs to be repeated on a standard interval?
Is it required to have a backup instruments to the EFIS ? I know it's the better
practice to have those, but are they required in experimental?

Subject: Avionics-List: Equipping experimental for IFR
From: "curts63" <curt.stein@verizon.net>
I"m new to owning a plane and trying to learn. I bought a used
experimental plane.
The panel includes an MGL Voyager EFIS, Backup airspeed, Backup
altimeter,
Garmin 430W, Garmin GTX-327, Garmin 240 audio panel, and a Navworx
ADS-B.
The Voyager has the horizon, slip skid ball, compass, altimeter,
airspeed, OAT,
clock, timer, oil temp, oil pressure, RPM, CDI, glideslope, autopilot,
and more.
My question is, what is the required equipment for IFR and what testing
has to
be done prior to filing and flying?
Any insight and guidance is greatly appreciated.
Thanks, Curt

Yes, the IFR altimeter/static test involves checking every 1000 ft up to
max altitude you want.
No on repetition of the 430. See AC 20-138A
No backups required for experimental, just Part 23. Good idea to plan
what type of backup you want.

Hello Curt, You wrote:
1) Does it have to be field tested/certified prior to IFR flight .....?
a) Lets take the certified part first. This extract:
Fly WAAS Approaches
GNS 430W comes with built-in WAAS navigation capabilities. It is approved to
fly LPV glideslope approaches without reference to ground-based navaids of
any kind. Featuring an advanced 15-channel receiver capable of five position
updates per second, GNS 430W meets the FAA's stringent TSO C146a standards
for WAAS "sole means" navigation providing vertical and lateral approach
guidance into thousands of U.S. airports previously inaccessible in IFR
conditions.
copied from a Garmin page shows that the 430W is fully compliant with TSO
C146a for sole means navigation including precision approaches. No further
certification in the field is needed.
b) Regarding field testing: There are no provisions in the federal
regulatory system for the FAA to field test the avionics installation in
your EAB aircraft. One may turn to an FAA approved MRO (Maintenance and
Repair Organization) for such field testing, but that organization is
obligated to comply with some regulatory provisions established for type
certificated aircraft which do not apply to your EAB. In the MRO's misguided
attempts to comply with type certificated aircraft criteria in regard to
your EAB you can wind up with a real (and expensive) mess on your hands.
So my recommendation is that you use an FAA approved MRO for the bench
testing and repair of your individual avionics components when required, but
do not attempt to have them field test any EAB entire avionics installation.
b) .... does it need to be certified on an ongoing interval,...
No regulatory recertification for the 430W is required, but there are the
issues of navigation data base and software updates:
a) Navigation Data Base Updates: This can be an ongoing chore / expense
depending upon how you approach it. The ultimate (and most expensive)
navigation data base update solution is to have a Jeppesen subscription that
provides one an appropriate geographic navigation data base update every 26
days that you must download with your computer onto the navigation data base
card for your 430W and then install in the unit. An alternative is to call
Jeppesen to order and install a one time navigation data base download when
you see the need.
b) Software Updates: If you poke around digitally inside your 430W you will
discover an amazingly large number of different software programs that
control the various aspects of that box. You can write down the identity,
including the version, of each of those software programs and carry it off
to a nearby qualified Garmin dealer / servicing facility. They can check
their Garmin files to see if there are any available updates to those
software programs. Those updates will fall into categories such as mandatory
(in Garmins opinion) or sort of nice to have. Use your judgment as to
whether you want to go to the effort / expense to have any software updates
done.
Please let me know if you have any further questions.

Owen, Thank you for the equipment list, that helps with whats needed for
flight rules. The one outstanding question is with the Garmin 430W. Does
it have to be field tested/certified prior to IFR flight and does it need to
be certified on an ongoing interval, like the transponder?
Sincerely,
Curt Stein

I am aware of no regulatory mandatory requirement to check the GPS accuracy

check into the subject of RAIM (Receiver Autonomous Integrity Monitoring).

As you imply in 1 above, if you are using the VOR capability of the 430W for
IFR navigation then you must comply with 14 CFR 91.171.
3) "You don't need a signed flight manual supplement to go along with the

Here you are treading into the area of trying to super impose regulatory
requirements established by the FAA for type certificated aircraft onto the
far thinner regulatory arena that EAB aircraft operate in. Where is the
regulation that requires a POH for an EAB aircraft? Where is the regulation
that says who is authorized to sign the flight manual supplement for an EAB

It is my pleasure, sir.

You are welcome any time.

**PS: I would recommend extensive practice under VFR in VMC conditions with
your aircraft's avionics installation before venturing into IFR under IMC
conditions.
##PS: I am not saying that a good POH / supplement is not needed for safe
flight in EAB aircraft, just that the FAA does not mandate those items by
regulations and it is up to the builder / pilot of the EAB aircraft to
create what is needed for safe flight for him and his aircraft.

Owen,
So in conclusion, the 430w does not need any kind of test prior to using it
in IFR conditions? There are no mandatory tests like you would see in the
VOR area where you're required to check the accuracy? You don't need a
signed flight manual supplement to go along with the POH?
I do know about the monthly nav data updates from Jeppesen. I did purchase
the expensive annual update package for my intended area of flying.
Thanks again for your assistance. I really appreciate you taking the time
to educate me.

I strongly recommend following the guidance of AC 20-138A (available for
download from FAA) when installing a certified GPS in an OBAM
experimental aircraft.
Item 22 on pg 37 is Installed performance-ground tests. Ensures there
are not interference issues with other installed avionics.
Item 23 on pg 39. Installed performance - flight test. Again,
suggestions to ensure flight guidance, especially for approaches is as
expected.
Not regulatory, but highly recommended. The AC also has some guidance on
flight manual supplements.
Generally not a big deal, unless you plan on having someone other than
yourself fly the plane.

The Garmin 430W install manual has a checkout procedure as well.
FWIW, I do know the local avionics shop here has a pilot they use to shoot various
approaches in VFR to verify all is well. I don't know that it's required,
but it seems only prudent to do so.
