    So once again, the "performance requirements" have been met by the GPS 20-A as a WAAS position source for ADS-B, but would this hold water to meet the requirements for navigational purposes into IMC??...I don't know, but it sure would be nice if it did. So I guess this begs the question...."what's the penalty if you were to get caught during a ramp check with "inadvertently" navigating through IMC with equipment that you "thought" was approved for IFR/IMC flight"?

    If this option is not viable or practical then it will probably be a deal killer for the FX which would be really sad. I would end up in a Husky or a Top Cub or even worse - a Wichita Bug smasher.

    That's the beauty about experimental...you can design your panel any way you like. I think a GTN 650 would be a nice complement to the CC. You mentioned placing the GPS antenna on the belly....that may not be a good idea. Comant makes a nice GPS/Com antenna ( I think it's the CI 2590) that you'd mount on top of the airplane where the build plans instruct you to do so. Also, if you installed a GTN 625-650 you wouldn't need the GPS 20-A because the GTN could interface with the ES transponder and provide your position source for your ADS-B out.

    You're right about that. I forgot about the need to be able to have line of sight with the bird in space. I am curious how the Comnant would mount on a rag and tube airframe. Guess I'll have to take a look at how some of the installs are done on the Top Cub or similar.

    If you went with the GTN 650 , I think the only other equipment you'd need is an audio panel. Remember, you'll also be able to delete the GTR 200 Com radio because the GTN 650 has a com built into it. You'll also need the GAD 29 which provides an ARINC 429
    data interface between your G3X system and
    various IFR-capable GPS navigators, such
    as the GTN 650. This is just a small box that's mounted remotely and it's similar in size to the GPS 20-A. I'm sure if you're planing on going with CubCrafters FX program they'll be able to design your panel any way want. Like the song says "all it takes is looks and a whole lot of money"!!

    If you use the VHF/GPS combo antenna mentioned above, it would get mounted to the aluminum turtle deck just behind the skylight. This is the location we are using for the antenna used with the GPS 20A.

    I think you are right. The whole idea sounds too cost prohibitive. I think I'll just stick with their standard Exec glass panel package and rent a 182 at the local fbo to meet VOR int/tracking currency requirements.

    There was another post on that installation but I think it mounts in the same location that the standard com antenna mounts up on the turtle deck. I believe a small modification had to be made regarding the holes, but I don't think it was a big deal. I'm sure you can search previous post and read about it and see the pictures that were included in the post.

    Thanks Matt. Since the 20A is waas capable, can you load a GPS LPV approach into the g3X ?

    Another option would be the GNC255 nav/com in place of the stock com radio. The dimensions are just slightly different. I would think that no audio panel should be needed since there is only one radio. I would use this in conjunction with the remote mounted GPS 20a.
