AOA Cal

[tomkk]

The Skyview AOA cal procedure is pretty easy to go through. I did the cal (RV-12) with full flaps, figuring that would be best for landing AOA indications. I set the warning to start at the bottom of the yellow. The result, though, was an AOA warning that starts just before touchdown, near the stall. I did a recal with flaps up, trying to adjust the start of the warning earlier. That overshot and it now starts too early. Next time I'm out I'll try it again with half flaps.

My goal is to start the warning with a slow beep at normal approach speed and have the beeping accelerate as I slow to the fast beep just before stall.

I've never flown with AOA. So, first, does the way I'm trying to get it to alert me make sense? Second, is there a way to configure Skyview AOA manually, without a trial and error recal process until I get it right?

Tom:

If you have a standard RV-12 as supplied by Van's, you don't have a Dynon Avionics or AFS AOA/Pitot Probe - you have JUST a pitot probe at the tip of the prop, and thus the SkyView AOA feature won't work (no AOA port).

SkyView (and our earlier EFIS products) require that you have the Dynon Avionics or AFS AOA/Pitot Probe installed to accurately measure and display AOA. The AOA calibration procedure measures the pressure differential between the Pitot port and the AOA port, using the known geometry of the Dynon Avionics or AFS AOA/Pitot Probe, during the calibration maneuvers to determine your plane's AOA.

If you did install a Dynon Avionics AOA/Pitot Probe on your RV-12, no, there's no way to configure the AOA manually without doing the calibration procedure as described onscreen. Feel free to call Dynon Avionics Technical Support - 425-402-0433, and ask to speak to one of the pilots for some tips on doing the AOA calibration procedure.
