How to Calibrate Angle-of-Attack on Garmin’s G3X Touch System


For pilots who fly with modern electronic flight instruments, having access to accurate, repeatable angle-of-attack (AoA) information can be transformative. But before you can use it, you have to calibrate each installation. KITPLANES editor at large Paul Dye literally flies us through the calibration process for the Garmin G3X Touch in his wife’s Van’s RV-6. It almost takes longer to describe than to accomplish, but seeing Paul do it should help guide the way.

  1. Thanks Paul. Mine is calibrated but wanted to do it again and this helps. If you are cold out in Dayton, you should be here in Michigan!

    • Yes, as I think we mentioned in the video, you can repeat the calibration for the “flaps down” case, but the process is absolutely identical, and I hate long videos…

  2. G3X has a flaps down calibration in addition to the flaps up calibration shown in the video; instructions in the G3X manual.
