A GTX330 doesn't exactly imply "deep pockets". Wasn't a UAT estimated to cost several thousand bucks? It's going to run you considerably north of $10K for a full certified installation and somewhat less if you already have a MFD. Hardly. My airplane already has a GTX330 and a GNS430W. Garmin says that they'll implement ADS-B on those two boxes; the GTX330 will require a $1200 upgrade, but the PowerPoint I saw was unclear on what the GNS430W would need. I doubt that a UAT will be that inexpensive; there's also the minor problem of needing panel space for it, something that's in short supply in my airplane. Dudes, the implementation of ADS-B with an existing GTX 330 system makes sense for two simple reasons: 1. UATS are currently vaporware, or very costly ($10,000 or more). 2. Even after this "golden child" UAT shows up, you are going to want to use 1090 to talk directly to airlines, which will be implementing that only. Unless you believe that the FAA is going to faithfully translate that information for you, after bouncing that down to a ground station and back up, perhaps with a mountain in the way or two. If you search back in this group you will see that I brought this issue up years ago. The "dual system" will have to go down as one of the most spectacularly bad ideas the FAA has ever perpetrated, and it WILL result in the FAA performing a power shrug while trying to explain to the press why two ADS-B equipped aircraft, a light airplane and a regional heavy, collide with loss of life. As for me, Garmin has once again (apparently) saved me from the FAA. I'll get ADS-B capability long before GA gets it, via the GTX 330, and after UAT becomes reasonable, the GTX 330 link will make sure that the heavys know I am flying around, whether the FAA gear is working or not.
