Well, I just got caught up on this thread - it's gone places.
I appreciate the comments and interesting (and not interesting) tangents. Another option for me would be to go with a Garmin 300XL as my IFR GPS (those can now be had for very cheap) and go with the SL-30 as well. (The SL-30 is actually really two nav radios in one, for those who aren't aware - it can simultaneously tune two stations.) The GRT EFIS talks to the 300XL as well which is good. My 2nd EFIS screen would then be used mostly as a moving map to supplement the 300XL's display, which is lacking. With this setup I can get down to $21K of equipment all-up with my IFR backup analog stuff, transponder, etc. The only thing I am giving up that I can see is WAAS approach capability - I don't believe the 300XL is WAAS upgradable.

Seems to me that flying IFR GPS, with mostly GPS approaches in the near future, I should not have much need for a 2nd VOR receiver to identify intersections - obviously the GPS does that itself and the 430 does have one nav radio built-in. Only problematic area I can think of are the cases where 2 VOR receivers are pretty much necessary - to identify FAFs on ILS, LOC, and VOR (no GPS overlay) approaches. I release that ILS's almost always have an OM anyway and VOR IAPs w/no GPS overlay become scarcer by the month. With WAAS.. much less of a problem all around (WAAS precision approaches). If I decide I can do without another nav I save $2000 going with a SL-40 (com only) vs a SL-30 (nav/com). Interesting in hearing from people with 430s (and up) how they are flying the things. (As for navigating with the 430 tango uniform - there's ATC vectors & the backup handheld GPS.) |
