At any rate, I was thinking about getting a Garmin GNS-430W, but at $10K installed it's a big investment. The other 50% cheaper alternative is keeping existing nav/coms and getting a GPS-only Garmin 400W. WAAS would be a great thing to have, seeing as there are more LPV approaches out there nowadays than ILSs. However, Garmin has a monopoly in Panel mounted WAAS avionics, and I can't seem to find any cheaper viable alternatives.
Since the plane would be based in the DC area, the added situational awareness of a moving map will help tremendously in not busting the DC FRZ. Also, we'd be adding value to the plane, which would help if we decide to sell it when the economy picks up again.
Here's what the panel looks like currently:
A bit cluttered, but it works-ish This plane is already a great long distance cruising machine (nearly 140 TAS at just 9ish GPH) and is a very stable IFR platform. If this was a vintage C172 I don't think I'd ever consider doing this.
Anyways, I was wondering what you guys think, whether it's worth the investment or not or if you have any better suggestions.
