Hi
Flying my RV9A and I think I may have some instrument error. I suspect problems with temperature or position error on the static port.
A few observations:
Altitude is about 600 feet higher consistently on my GRT Sports than on my ipad gps derived altitude. (at approx 10000 ft)
The wind when flying into it are always a lot higher than when flying with a tailwind acording to the efis's or is that efi? They are separate ahrs. buit the read the same.
The temperature probe seems to read 4 celcius high.
The pitot static system has recently been tested and adjusted by a certified shop. o leaks and both altimeters and all three air speeds match.
TodayI was indicating 147Kts with 169 ktas and 194kts gs temp -18 c and 10800 ft, the ipad showed 10200 ft
is the problem position errror or temperature error or both?
would appreciate the brighter folks than I to chime in. ( that means just about everybody )
