Which remote Garmin ADSB to Legacy G1000

[drstephensugiono]

You can get a Mooney with the G1000Nxi.  You just have to buy the Acclaim M20V.  I've flown and taught in all models of Acclaims, and while they are fast and fun to fly, upgrading your M20M with all the avionics you ever dreamed of having is the way to go in my opinion.  You could put your dream avionics in and still be all in for half the cost of an Acclaim.  The only reason you would buy a regular Acclaim would be for the extra speed, and for most trips the time saved isn't that much.  Or am I missing something?

Why could they put a G1000NXi on the M20V with the same fuselage and can’t grant the same for the M20TN??

It's not the same fuselage.  It was certified with 2 doors and the G1000Nxi.

I don’t know if I’d go through the cost and aggravation to go Bravo -> Acclaim. Transaction costs, catch up maintenance, downtime, etc are significant, especially if importing a non-WAAS plane. The acclaim is faster and has longer legs, but unless your 90% mission needs the range, the trip time will be similar.  In Illinois, where my plane is registered, sales tax alone would be the better part of $30,000, and unless you can run a trade through the seller’s balance sheet, sales tax is collected on the purchase price, not the delta.
 
In your shoes, I’d take the money and do a modern Garmin autopilot and panel.
I got WAAS-compliant with a 330-ES transponder, which was maybe half or a third the cost of a 335. It won’t do ADS-B in, but I don’t care.  While out of production, you probably could find one.

I did buy a Garmin GTN750 for the Bravo sitting on my desk in a box with new tray and hardware I got from an acquaintance that took it out of his Pilatus. I was on the market for a GTX345, like that on my Swift that would communicate with it.
I hate to say this but flying in a 6 Pack makes me feel like a real pilot. I’m old pilot

I know I know there’s an extra door but seriously?!

Bottom line, it was certified with the G1000Nxi and that's all that counts.  Mooney did that when they were viable.  They are not now, so no upgrades to legacy G1000s.

Wonder if it had the same GFC700 Autopilot?

It does.

Is there any benefit to the WAAS upgrade other than being able to shoot RNAV approaches when the ceiling is below 500 agl? Can't imagine it makes any meaningful difference for lateral guidance.

Depends on the airport. I have seen LNAV mins as low as 315 ft and some as high as 700 ft.  Precision Approaches (and autopilot coupled approaches) are limited to ILS without WAAS and those keep disappearing. Also ILS seems to be more likely to be out of service than LPV.  A coupled precision approach can be a real help on a long tiring flight in bad weather. 
 

Of course we used to fly without WAAS or even GPS but I don’t want to go back…

Another benefit is that all of our airplanes will get sold someday. G1000 airplanes without WAAS linger on the market for many months and many times the seller ends up having to discount more than the WAAS upgrade price since the perception of the buyer is, "What else have they cut corners on?". Also if there are no WAAS units available down the road the discount might be a fire sale price.

My thinking would be: "If you're going to end up "paying" for the upgrade when you sell it, in the form of a discount, why not upgrade it now and get some benefit out of the upgrade while you own it? Then when it does go on the market someday down the road it should sell a lot sooner."

Aim small, miss small…

It is comforting to see the centerline of the runway on your pfd align with exactly what you see outside the window.

It's amazing how well that actually works, too. I was practicing uncoupled the other day and marveling at how well the SVS and calculated velocity vector work.

Some people over on BT have been playing with landing 0-0 using synthetic vision.

The only issue has been the flare.  

Hmm, sounds like having an LHS would solve that problem.  I need to give it a try.

"Wow, Dave, that landing was different. It's usually rougher..."

When I did my instrument check ride more than 30 years ago my examiner had me continue the ILS to landing under the hood just using the pressure altitude to decide when to flare.  It was certainly an experience and not my best landing, even back then.  He wanted me to know it would be survivable I guess.

I have recently done an LPV approach under the hood with a safety pilot and used the LHS to decide when to flare.  Worked out pretty well.  Certainly hope to never need it but much more than just survivable.

[Pinecone]

Synthetic vision would make it even easier.

Only the GIA63W with an -01 or a -20 suffix are compatible with the system in the Mooney.
There has been much discussion on here about the G1000 NXi. Mooney has to initiate it and pay for it.
Figures have been thrown around as far as what Mooney would have to invest. I've heard $200,000 plus whatever outstanding money that Mooney already owes Garmin.

Which suffix is more favorable? The -01 or the -20 ? Elaborate please

Going to have to agree with @donkaye, MCFI. While the G1000 is a fine and capable system, it's getting a little dated. I fly a lot of IFR and would absolutely not buy one without WAAS. I know that there are folks that don't fly the same profile as I do and to whom WAAS capability is not critical. I have all the latest avionics in mine G3X, 345, 750, GFC500 remote audio panel etc etc. and I couldn't be happier. And even my 4-year-old panel is not state of the art anymore! My 750 has been superseded by the 705Xi.....I love having the ability to upgrade if I want to (although 750 to 750xi is not a priority).

Whatever you get - its a Mooney and you'll love it! Good Luck!

They both work, but what I've heard is that the -20 is upgradable to the NXi if that ever happens through Mooney, although highly unlikely.

The G1000 is a bit dated but still works fine.  I have my 2007 Acclaim and a 1980 King Air F90, the Acclaim has the G1000 and the F90 is decked out with dual 750s and 600s and if there was an option to put the 600/750 combo in the Mooney Acclaim I would do it in a sec.  I tried to look at upgrading the G1000 to WAAS but there is no benefit to doing it in Brazil.  I would like to put ADS-B in it to remain compliant in the US but I don't think I'll ever fly it there.  I had a Cirrus Vision Jet for a while and flew that to the States and have flown my King Air up there as well but for the Acclaim it would be more of an adventure than a trip.

The guys that took out Mooney had said they were going to work on the Nxi upgrade but I guess that is dead now?

I wish I can put the NXi swap, I’d do it in a heartbeat!
