D6 EFIS in Warrior?

[wiwarrior]

I am searching out a secondary attitude reference for my Warrior, while 'VFR only' may not make sense, it's O.K. with me. While thinking about the electric attitude gyros I came by the idea of installing a D6 EFIS in a vacant 3 1/8" hole. Is this doable? Other options?

I wouldn't need all the data sensors hooked up & active to start off, is it possible to just go with attitude & not hook up speed, alt etc.. right away?

Just wanted to ask before I dropped $$ with a similar priced backup gyro. OSH is a ways off & wanted to ask. Thanks.

It is allowed in Australia. Our backward thinking CASA have for once been very forward thinking onthi matter. For a backup in pvt ops it is allowed, commercial ops it is allowed but you still need all the regular stuff.

If the FAA only followed our lead forth is one life would be great with a heck of a lot of peopl in he USA and elsewhere.

In my opinion the baby Dynon makes for the best backup in a certified plane, with backup battery too!

Petition the FAA

My research is leading me to the conclusion that it is not allowed in a 'certified' plane. I do have a lead on a slightly used Castleberry gyro that I plan to check into.

That's an interesting question that came up here also. Is it any different then mounting a handheld GPS in the panel with an AirGizmo panel dock? or sticking a clock in a convenient place. Is there anything that states that you can't mount something on your panel providing you already have all the certified equipment required for the type of flight?

Our instruments couldn't reasonably be considered portable because they need pitot/static for proper operation, and are designed to be used with ship's power.

But as for the secondary nature of the instruments not being OK, here it is from the horse's mouth:

AC No: 23 .1311-1C - "Installation of Electronic Display in Part 23 Airplanes:
http://www.faa.gov/documentLibrary/media/Advisory_Circular/AC%2023.1311-1C.pdf

The excerpt you care about:

8.0 Flight Displays.
8.1 Instrument Requirements.
a. Sections 23.1303, 23.1305, 23.1311, and 23.1321, with the applicable operating rules
(14 CFR parts 91, 121, and 135), incorporate flight and powerplant instrument requirements for part
23 airplanes. The navigation equipment requirements are given in operational rules specified in
§§ 91.205, 121.303, 121.305, 121.307, 135.143, 135.149, 135.159, 135.161, and 135.165. Display
requirements for navigation information are dependent on the navigation system installed in the
aircraft. Instruments and equipment required for flights under parts 91, 121, and 135 may be
affected by the electronic display installation. These instruments and equipment include:
gyroscopic bank and pitch, gyroscopic direction, gyroscopic rate-of-turn, slip-skid instruments, and
other required communication and navigational equipment.

b. There have been applications to install equipment, such as flight and navigation
displays, as non-required. These applications request approval for these installations as situation
awareness (SA) only. It is not acceptable to label a display as “SA-Only” and assume that its
failure condition is acceptable. Installing displays that provide PFI that are more compelling than
the required primary PFI displays, but they do not meet the appropriate operational and
airworthiness requirements, and labeling them as “Supplemental” or “SA-Only" is not acceptable.
Section 13.6 provides more guidance.

c. The basis for certification has been that the equipment should perform its intended
function and not present a hazard. Instruments that aid situation awareness should be certified
under the part 23 requirements, including § 23.1301 and § 23.1309. These displays could provide
hazardous misleading information. PFI is essential for safe operation. An instrument that provides
PFI should meet the minimum standards of applicable TSOs or an equivalent standard. It also
should meet the guidance in AC 23.1309-1E, AC 23-17C, and the guidance in this AC.

So does a D6/D10A meet this and is therefore able to be installed?

 

[mmarien]

What I get out of that is if the equipment isn't certified it's not acceptable to mount them in the panel even if they are labeled as supplemental. Fair enough.

 

[dynonsupport]

Yeah, it's our understanding that you can't legally put even a chunk of plastic like an AirGizmo dock in the panel of a certified plane since it has no TSO or STC.

 

[wiwarrior]

Thanks, that does seem rather clear.

We don't claim that our equipment meets TSO or other certification standards.

 

[mmarien]

I just had a conversation with a guy that imported a Mooney into Canada recently. He had to remove the AirGizmo and GPS396 from his panel as required by the import inspection. Go figure eh?

 

[DBRV10]

Morons hey!

As you said....Go Figure!

Wy is CASA, normally so anal about stuff accepting of Dynons as backups. The FAA with head in sand...or another orifice.

This is a major safety benefit for little cost, and no negative I can see.

Stupid is as stupid does!
