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? ;-) > >Matt 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. - Matt "Red Dawg" Dralle RV-8 #82880 N998RV "Ruby Vixen" http://www.mattsrv8.com - Matt's Complete RV-8 Construction Log http://www.mattsrv8.com/Mishap - Landing Mishap Rebuild Log http://www.youtube.com/MattsRV8 - Matt's RV-8 HDTV YouTube Channel Status: 172+ Hours TTSN - Rebuilding Fuselage After Landing Mishap...
