G1000 WAAS Upgrade

[ChristianGodin]

Anyone can tell me what G1000 set up is upgradable at a reasonable price an what set up is not for now. Does the GFC700 compare to the STEC55 makes a difference? 

Thank You.

IIRC, only the GRC700 birds are WAAS capable as of right now. Mooney is supposed to be working on a solution with Garmin for the earlier models, which may or may not be reasonably priced.

This mean that WAAS capability is more related to the AP than the G1000?

No, I believe the STC that STEC has on the 55 in the Mooney installation doesn't allow vertical guidance on a GPS approach.

The STEC 55X is not capable of glideslope coupling on a GPS approach.

I thought all STEC-55X are glideslope capable. Isn't it the fact the non-WAAS GPS found in the Mooney G1000 can't produce the signal?

Au contraire mon ami. The 55X is incredibly cabable of glide slope coupling with an LPV approach because I did this regularly with my GNS480/STEC 55 set up in the J model. The issue is that Mooney and Garmin haven't collaborated to test and file the paperwork to permit this via the STC for the Mooneys. That is the big work effort which has been described ad nauseum on in a different thread.  Technically it's all very doable and easy...just need Mooney to get with the program and make it happen.

Have you guys waiting for this, can you add a WAAS GPS like a 650 or 750 and interface it to your the G1000? Is that possible, let alone legal?

I think it would be legal, but where would you put it. I've still been rattling the idea of putting in the waas Lru, antennas etc and changing my plane to experimental until and if Mooney certifies the plane. I've been contact with a Garmin Engineer and Avionics specialist whom requested I don't name them and the engineer let us know the cost would be viable. The protocol was laid out to me now the balls in my court. Wait for Mooney, do it, or trade down to a pre Gx model. All American has a plane that would make it possible unless I'd lose to much on my misfit.

I posted on one of the G1000 threads about this. When talking to my avionics guy he said he thought it was possible and would interface with the G1000. While space is tight it is still possible to get it in the panel when I was looking at it. It would seem to me to be the most cost effective method of getting WAAS into these birds.

There are over 3,500 WAAS LPV approaches in the US. A good reason to have a WAAS capable Navigator.

So, to get waas with a G1000 that is link to a GFC700 would cost a lot less?

[Glenn]

The STEC 55X will couple to glideslope in Approach mode.  It will not utilize raw GPSS data for glideslope tracking when it is in GPSS/APR mode.  I believe it has something to due with the fact that the autopilot was certified prior to the advent of the LPV approach.

IMO, the most flexible and least-cost solution is to get a pre-G1000 bird and update it with whatever systems you wish, such as Aspen or G500 and a WAAS GPS of your choice, such as GNS, GTN, or IFD.  You'll still have the flexibility in the future to improve the plane and not be held hostage by Mooney and Garmin to update a G1000 system.

The GFC700 is supposed to be the cat's meow, though, but I wouldn't trade flexibility for it when other autopilots still do the job.

To the best of my knowledge GPSS provides lateral navigation only on any system.

It is, nor would I.

I have Century 31 A/P on my 1982 M20J coupled to the GNS 530AW. And it does LPV approaches equally well as ILS approaches. I have not seen any limitation or restriction on an old A/P for GPS LPV approaches. Does some of the new ones can only do ILS but not LPV?

You're right from the units I have seen. I know on my Aspen GPSS, I can fly the full procedure in GPSS mode but need to make the altitude changes manually. I can however arm the approach on the autopilot while in GPSS mode and it will go into approach mode while the GPSS is still showing active on the Aspen.
