anyone help or seen this... repositioned the compass sensor to the wingtip. aircraft is rv-4 taildrager. recalibrated usng the procedure in the install manual. flew it for first time time today. although compass is seems bob on when on the ground, in the air it is by varing amounts way out...
Today heading south it was indicating 300 instead of about 230 for instance...
Did the calibration at the airports compass swing area - and as i mentioned all good on the ground.
When doing the calibraton - do we need to do it with the aircraft oin a level attitude or should it be ok when sitting on the ground ?
When i installed the remote compass i followed the instructions to the letter and it is mounted very very close to the required tolerances..
With this error... we were getting huge winds aloft reported by the D10A.
cheers
Any ideas ?
