They have got to get this STC below $100k for it to be a game changer. But, there are a lot of boxes being changed/added which all add$ up quickly.

This is not competition for Rockwell Collins. It is competition for Cessna Service Centers. Cessna already has an STC for GTNs in CJs and ADSB and WAAS.

It's about $125k for the CJ, and they say it will be a bit more complex box wise so that they Garmins will play with the P21 and provide WAAS / LPV.

Note that CJ is not PL21 which makes it a different animal. PL21 started with the CJ1.

Problem with this upgrade you are left with an expensive to maintain Collins instrument panel as it ages. From a TCO viewpoint it will be more economical over a 10 year period to upgrade to a G1000 or Proline Fusion panel.

My impression of the new Jet Tech STC, that differentiates it from previous 525 GTN installations, is that it now covers the CJ1+, CJ2+ and CJ3.

I'm sure there's more too it than this, but visually the cut-off point was whether the airplane originally had the Bendix avionics stack, or the Collins DTU's that are remoted to the FMC. The original CJ, CJ1, and CJ2 had the Bendix, and CJ1+, CJ2+, and CJ3 had the DTU's.

There was apparently some sort of technical road block with the DTU's and FMC integration, that had prevented installing GTN's on these airplanes up until now.

Another note with this STC is approval for LPV approaches. Don't automatically assume just sticking a GTN in the panel means you can shoot LPV's.

Synth viz adds no capabilities to any aircraft per se. You can't do anything "new" with it, at least legally.

But it does add a lot of situational awareness in routine operations and it opens up emergency uses, for example, deliberate below minimums approaches should that be required. Having better awareness of the terrain and the runway depiction makes it far more likely a below minimums approach succeeds. Synth viz essentially turns any IMC situation into pseudo VMC with all the extra awareness that brings.

I had forgotten about this thread, it is important to point out that the STC to convert a CJ to G1000 is owned by Textron and is dead. I wasn't aware of this back in 2017 when this thread was active. I wouldn't want someone to read this and think they can buy a CJ an upgrade to G1000, you cannot.

Yup, parts no longer available for the G1000 in the CJ STC. No SW updates for the G1000 in the CJ either. Features are frozen. Textron says parts for maintenance of current conversions still available.

Interesting, Garmin said it's a dead STC and that Textron isn't supporting it, i.e. no updates, no NXi etc.

The fact that this happens really bothers me. I actually believe that if a STC holder doesn't maintain it, the rights to the STC should be lost and the opportunity for it to be assumed by someone else.

I actually hope this is true and Textron is supporting it... but I bet someone is about to get a $750k quote for a non-NXi G1000

Chip, that could be the case. I’d still rather have non nxi G1000 vs early gen PL21 with Honeywell stack and a UNS. The G1000 makes the CJ a pleasant place to work. The 3000 is obviously more fun with touch screen, but I’m beginning to appreciate the twists of the knobs when things get bumpy.

Agreed!!!!

I've learned to love the PL21 UNS setup. I also have a Garmin 750/650 so I program the UNS & the 750. Its a bit of a PITA to switch between two completely different boxes to program in the same flight plan but when I'm done I display the plans on two different screens and if I made a mistake it become obvious.
