A few pictures worth 1000 words...today was cruising along at 15,500' MSL between 200 and 210 knots over the ground:

I was getting about 35 miles per gallon...way better than my Honda at nearly triple the speed:

And then of course there was the descent into the LA area...groundspeed was, well...acceptable:

These RVs are OK airplanes.

Dynon voltages

Great report, Dan!

Quick question about the voltages on the Dynon.

It shows:

M: 12.7V
E: 0.0V
I: 16.3V

Are these right? Seems both a bit high and a bit low!

Voltage on the Dynon

Yeah, that's normal for my setup. The D10 is on my e-bus. My main bus voltage is normally 14.1 to 14.4 according to my AF-2500 monitor, and that's the voltage reading that I trust, confirmed with a digital voltmeter.

The e-bus voltage is usually about 0.7 volts lower than the main bus by virtue of the voltage drop across the diode. And the D-10 has always read on the low side by at least one volt. It's a quirk of the D10 that I'm aware of and live with -- to me, what's important with voltage readings are relative changes.

I have heard from various other D10 and D10A drivers that the voltages they display are almost always off in one direction or another. I don't know why this is. To me it's not critical and I haven't bugged Dynon about it. I'm sure somebody will.

Dan, why is your heading on the Dynon off by 7 degrees? Is that noise error or is that heading as compared to true heading that the GPS is measuring and the TruTrak ADI from ground track?

 

[Mel]

Dynon reads the direction the airplane is POINTED. GPS reads the direction the airplane is TRAVELING.
Mel...DAR

 

[dan]

Exactly

It was a right quartering tailwind. And it's a Pictorial Pilot, not an ADI.

I forgot that the pictorial pilot is GPS driven and not magnetic. Cool stuff! Happy Flying!

Priceless. LOL

I'm gonna hook up my air line to my petot and see what I can get.
