I'm confused. This is a section titled "Minimum Operational Equipment (Serviceable)". In the US, I believe this constitutes the MEL, as interpreted by the FAA since it is in my AFM (downloaded POH is unofficial, BTW) and therefore applies. Other countries may have different perspectives. Some years back, the FAA took a position that raised a bunch of controversy. Many AFM's lacked this kind of specificity and there was a position that everything in the airplane had to be in working order or it was not airworthy. Having an actual MEL in the AFM is a defense against an enforcement of such a position.
It's a common confusion. The Equipment List in the POH us a list of aircraft equipment with notes indicating whether it is standard, optional, required, etc. It is definitely regulatory but it is not a "MEL."

A MEL is an official FAA term. It is list of specific equipment in a specific airplane which is permitted to be inoperative without going through the steps in FAR 91.213(d). The list, generally based on a master template, is submitted to the FAA by the aircraft owner/operator and approved by the FAA. MELs are discussed and described in FAR 91.213(a)-(c).

If you had a MEL, you'd know it because you would have submitted it to the FAA and received a letter of approval, it's unusual to have one in the Part 91 world, although I have heard of some flight schools getting them to avoid needing to ground airplanes due to certain discrepancies without needing a mechanic sign-off.

The "Minimum Operational Equipment" list in the AFM is different from both. It does not mean that everything else can be broken. Its more a KOEL in US terms. Primarily a recitation of our 91.205 and 209 bare minimum requirements, You'll notice the engine and prop isn't listed. You wouldn't argue it's ok to fly with a bent prop, would you?

Suppose today you wanted to yank out your G1000 equipment and replace it with something else that would allow software and other upgrades. Ignoring the chunk o' change this kind of panel rework always entails, what could you replace it with?

Not a solution today, but Honeywell suggest their Anthem solution will be affordable retrofit for very small aircraft.

Watch video here and note "very small aircraft" closing comments. Solutions will be found but suspect Garmin are conflicted so unlikely to help directly.

So if I were to strip off the G1000 from my 2005 DA40 w/ KAP140, then update to GTN navigators and G500 TXi display, I assume some of components can be still reused:


__ UNITS TO BE REMOVED __
2x GDU104x (PFD/MFD)
2x GIA63 (COM/NAV/GPS)
1x GMA1347 (Audio Panel)
1x GEA71 (Engine and Airframe) -- Looks like it needs to be replaced with GEA110 for TXi
1x GRS77 (AHRS) -- TXi has it onboard
1x GDC74A (Air Data) -- TXi has it onboard


__ UNITS CAN BE REUSED __
1x GTX3x5R (Transponder)
1x GDL69A (SXM Datalink)
1x GMU44 (Magnetometer)
1x KAP140 (Autopilot)


Sounds like reasonably doable.

According to Sarasota Avionics website, G500 TXi SVT enablement is only $1800 :shock:

Remember engine conditioning monitoring, including sensors. Seems like a challenge for the diesel-powered airframes.

Getting rid of the G1000 is only legal for Lycoming-powered DA40s with the G1000 originally installed via Garmin STC.

For years the discussions here all assumed there was no way any of the G1000’s could be replaced sans Diamond participation, but suddenly the landscape has changed. I was pointing out that there was more to the change than one might think at first and likely extra tricky should the situation also come to be different for the diesel versions.

Agreed. It is head-spinning, but our friend with the elderly G1000 DA-40-180 makes an excellent point that was obvious (in hindsight). A supplemental change can be unchanged.

In thinking on this for the last few days, I cannot see why you can't put in any instrumentation you want. The engine is a nice 1941 Lycoming that can be monitored by any monitoring system. The flight instruments are generic. There are no airframe-specific sensors or systems other than the autopilot.

As noted, this situation only applies to the DA-40-180. It means that we can have your setup. There is a small, but non-zero, chance that someone might take the lightest weight, too. Woot!

Yet another example of how DAI's lack of avionics support for the G1000 negatively impacts owners. Aircraft are certified with avionics which have known bugs and Diamond owners will never receive a fix.

So we, who have GDU 9.x, can consider ourselves lucky :D
