it seems like the airspeed is reading maybe 10mph fast. The GS always reads
10mph or more slower than the True airspeed, no matter which way I fly with respect
to the current wind. Looking through the configuration options on the Skyview,
I'm not seeing parameters to calibrate the airspeed. If the airspeed
were *slow* compared to the GS, I could envision making adjustments to the Pitot
tube to get it in better alignment with slipstream. But *fast* is a head scratcher.
If there's no electronic configuration parameters to adjust, what do
you do? Are there Pitot line "attenuators" like for RF in coax? ;-)

Listers,
I went flying tonight in the RV-6 around sunset and took some airspeed numbers
flying the four points of the compass. I let each direction normalize for about
2 minutes before taking the readings. I've still got my little black-tape
washer deals on the static ports that I detailed in a previous email.
Do these numbers make any sense?
Emacs!
I set the altimeter to 30.15 (KLVK ATIS). I compared the Dynon altitude with the
Garmin 696 GPS altitude. The Dynon was high by 100 ft. I used the Dynon altitude
adjustment to set it to match the GPS (-100ft). The readings above were
after this adjustment.
