Debated about hijacking this thread vs starting another one,
but I am in a very similar situation to the OP.
I have a GNS-530W and a GNS-430 (non-WAAS) in the Aztec, and am also contemplating ADS-B options.
I currently use Foreflight with a little FF "Scout" ADS-B In receiver.
Current transponder is a well used King KT76A.
Big picture plan: Rework the center stack including a) removing the inop King ADF, b) install a new audio panel with integral 6-place intercom (leaning to the PS Engineering 450B), c) install the long overdue Flightstream 210, d) install a (currently undefined) ADS-B solution.
Preferences:
- No motivation at this time to replace the GNS 530/430 boxes with either a GTN 650/750 or Avidyne. Not enough incremental functionality over the GNS capability for the flying I do to justify the cost at this point in time - if one of them quits I'll probably look at the Avidyne option at that time. The FS-210 will eliminate a lot of the knob twisting.
- Considered the GDL-88 but don't really want to spend that money and then have the aging KT76A transponder quit and have to replace it. So a replacement transponder seems almost inevitable. When I pull out the King transponder I can use it to spare the same model that is in the Husky as I don't need or intend to install ADS-B in that plane.
- Prefer not to have an ADS-B solution that has its own WAAS GPS if it requires another GPS antenna on the plane - I already have two GPS antennas, prefer to avoid adding a third and would like to use the 530W as the position source instead.
- Not fussed if traffic and weather not available on the 430 or 530 screens. I tend to have the default nav page up on the 530 most of the time in the air. Screen resolution isn't comparable to the iPad for that sort of stuff imo.
- Must have the ADS-B traffic and weather on the iPad, the way I have now with the FF Scout receiver.
- Barring a failure of one of the GNS boxes this is likely to be the last significant center stack investment the Aztec will receive while I am the owner of the plane (figure 10 more years), so I am going to spend more than the absolute minimum needed to comply with ADS-B Out only.
Have been leaning to the GTX 335 or GTX 345 solution. The desire not to add another GPS antenna seems to be forcing me in the direction of Garmin.
What would you folks do?
Do I understand you have an NGT-9000 that "talks" to your 430W and displays the ADS-B traffic (closest 8 targets) on that screen as well as the touchscreen on the Lynx?
