I must be missing something, but it seems that I could get Papa set up for non-precision GPS IFR with a 2-axis autopilot for under $10,000. Interesting, yes, but it still ignores the issue of where the $10,000 is going to come from. Let's just wish that little problem away for the sake of argument, though.
So here's what I'm thinking:
A Dynon D-6 for attitude.
A Dynon D-10A for navigation display and autopilot control
A Garmin GNC 300XL TSO for IFR GPS and Comm.
The prices break down thusly:
- D-6: $1,600
- D-10A: $2,200
- GNC 300 XL: $3,150
- Heated Pitot: $450
- OAT Probe: $ 65
- Backup batteries for D-6, D-10A: $260
- Roll servo and mounting kit: $825
- Pitch servo and mounting kit: $825
You'd have to add some dollars for wiring, etc. but that shouldn't exceed $500. And because it pains me to do it, I'm not including sales tax. That would probably put me over the magical, mythical $10,000, but literary license allows me to ignore that for now.
Here's kinda-sorta what it would look like:
And what would I get for that? Well, the IFR minimums for a GPS non-precision approach into Bolton are right around 500(AGL) and 1/2 mile visibility. An ILS set-up would add thousands of dollars and only get me 300 feet lower, so I deem that to be "not worth it."
IFR aside, just the 2-axis autopilot would make it worth the money. It's hard to quantify safety-of-flight value, but the value of an autopilot is pretty easy to understand.
So, here I am back to Dynon. How long have I been stuck here? Since four days after I took delivery of Papa, as it turns out:
If I were to do it now, though, I'd move the Dynon units one row to the right on the panel. They'd be closer to the GPS/Comm that way.
