Good news and More Good News

Yesterday was a happy accident. I was scrounging some exhaust gaskets at AvTech, when I overheard a conversation that an AvTech alum was bringing his transponder and static check equipment to KMDH. I asked to be put in the queue and as luck would have it, I was in.

John checked at least two C-172, I think a C-182, an LSA, a Cherokee 140, and the mighty Q-200. All in a matter of a few hours.

This was particularly great, since I wasn't really sure how accurate my systems were. In the conversion, I had discarded the altitude encoder and now use the Dynon D180 with the gray-code (whatever that is) converter for altitude encoding. I had no way of knowing if it was even wired correctly until the checks had been done.

We hooked everything up and John fired up his test device and gloriosky! The transponder and altitude reporting were spot on.

Next, he checked altitude calibration. At 10,000 feet, the Dynon was only off by 20 feet (10,020 ft.), which was well within specs.

Finally, we did the airspeed calibration, and this was the happiest news. My airspeed indicator is reading a little low, so when the airspeed indicator reads 196 mph, I am actually going 200 mph! I just got four more miles an hour!

It's the little things in life.

Excellent.
