Hi all, new to AOA and have it installed on my Skyview. Question do I set up stall speed clean or with full flaps?
Hi all, new to AOA and have it installed on my Skyview. Question do I set up stall speed clean or with full flaps?
So it must be different for the older Dynon D-180. I read where it says to do it with flaps and without flaps. That would also make more sense because if it's only with flaps it won't work well when doing an accelerated stall like on take off or on a go around after you raise the flaps.
My AFS/Dynon setup came with a very detailed in flight calibration procedure for the AOA .
I have a copy if you need it.
Yes, it's different, because *it's not a D-180*. Sigh.
Thank you for being so condescending, you reminded me of my daughter when she was growing up and sighed at me, once. Hasn't done it since.
Having you here on the forums now will make everything a lot faster to find, just ask you since you know everything about everything.
Thanks for all the replies, found some on the Dynon forums also. Great help, plan on setting it up tomorrow for landing full flaps.
FWIW: Calibrating the DYNON AOA probe is done the same way on a D100, D180, D10A, D6 and the SkyView as per the installation manuals.
This is what I have on calibrating the AOA which says to do it WITH FULL FLAPS and WITHOUT FULL FLAPS.
The Skyview calibration instructions are provided *on screen*, not in the manuals (other than that they say to follow the on-screen instructions). The on-screen instructions say to perform ONE stall, and nowhere mention this list of configurations. It does say on-screen that you *can* perform stalls in other configurations, but per the Dynon forums and various threads there, each time you do, it *resets* the stall speed to the most recent one...no averaging or finding min or max AoAs or the like.

Please read pg 15-3 of the Skyview Installation Manual V15.3.3. It states in the screenshot of the on screen display:I'm sorry, but this is just not true.

Only if you press "SAVE" does it overwrite the old data. Otherwise it uses however many stalls you accomplish to calculate an AOA point. As I said in Post #11: "I calibrated mine <SkyView> with 1/2 flaps. That way it provides the best balance between no flaps and full flaps. To me AOA is a tool, not a crutch. YMMV"
If you perform multiple stalls during the test, it will look for and use the AOA calibration that results in the most conservative stall warning.
No, that is not what I said.Wait, what? If you don't press "Save", it saves some sort of average value, but if you press "Save" it saves the last value?
No, that is not what I said.
It uses that value and the previous others to calculate, via some "propriatory formula", an AOA. The formula is only run after you press SAVE, which is the most conservative one in that series of stalls. At least that was how it was explained to me by DYNON engineers back in 2011when I was researching which EFIS system to install.
FWIW I have done AOA calibrations on D6, D180, and SkyView systems since 2011. For my personal airplane I only did a 1/2 flap stall since, at least to me, it gives the best overall AOA alert operation across all configurations. So this method has not changed since at least 2011 for any of the DYNON products. YMMV

Debe de ser de Jalisco porque no quiere perder !!!
The highest AOA you demonstrate during calibration is going to be the red zone.
If the AOA algorithms are looking for the lowest angle of attack, for example, and then just taking the minimum value of n values and updating the system if and only if the SAVE button is pressed, that's a lot different than what was stated.

Thank you for confirming what I stated back in post #18:
Nope, never have. That was a task people I supervised did.I'm going to guess you never wrote code to find an extrema from a sequence of user inputs.
