Default AOA Report

Installed the AOA modification in accordance with the direction provided by Joe Gores (Mich48041). Used the football needle, some 1/8" O.D. tubing, the quick connectors at the wing root as suggested and the fitting on the backside of the Dynon as suggested. Part numbers can be seen earlier in this thread.

It is amazingly accurate!!

This evening did a series of landings and stalls. I have the AOA set to start to alarm (beep slowly) when it is in the middle of the yellow band. On landing it started to beep slowly when I stopped the descent, and then a solid tone just when the wheels touched. My normal stall warning never sounds on landing with only me in the plane, it only sounds when nearer to gross weight.

When doing the full stalls at altitude, the AOA starts to beep just before the stall and the solid AOA tone sounds right at stall. If I slow just a bit more (with only me in the plane) the normal stall warning sounds. (My stall warning vane alarm may be coming in a bit late.)

Will have to do a bit more testing and determine the TAS, with full flaps, when the AOA just starts to beep slowly. More testing to come.

One suggestion..... Do not turn the AOA function on until it has been calibrated per the instructions in the Dynon manual. I turned it on prior to my 1st calibration flight. The AOA alarm blared in my ears as soon as I passed 35 knots just prior to liftoff.

Thanks Joe!! A $20-$30 modification that is well worth the insignificant cost.

Good going Marty, getting the AOA working.
For those who have the Dynon D-180 and installed AOA but do not hear the woman's voice when approaching stall AOA, it seems that it is necessary to have either the AP74 of HS34 in order to hear the voice alarms. And the voice must be enabled in the AP74 or HS34 setup menu.

Does the installation in the Skyview have the AOA hooked up or does a similar type of mod need to be done like previously mentioned for hooking up a AOA probe?

Thanks,

Bob

The E-LSA Skyview instructions and parts do NOT include the AOA parts or installation. It is very easy to add per the instructions in this thread.

If you want to install the AoA sensor (and/or pitot) in (on) the wing, and are not comfortable with the twist-lock fittings recommended earlier, I can highly recommend these quick-disconnect fittings:

http://www.mcmaster.com/#standard-qu...ttings/=lj5z09

They are a bit (O.K., a LOT) more expensive, but they have O-ring seals and really do disconnect (and connect) quickly. They are also vibration resistant, and you can get bulkhead mount versions that may be useful in this application.

I can highly recommend the KQ2 line of fittings from SMC. I replaced my entire pitot/static system with new hoses and KQ2 fittings when I installed my Dynon. O-ring seals, vibration resistant, bulkhead mounts available.

SMC even makes a Flame Resistant line, the KR series. Not sure why you'd need them in the engine compartment, but if you're anal about flame resistance you could use them in the cockpit too.

Has anyone tried to silence the woman yelling STALL and still been able to keep the side tone beep?

I just set mine up to start the side tone at the top of the Yellow. The stall warning alarm comes in just before the solid tone, but I find the woman yelling STALL to be distracting.

Try deleting the stall switch from the Skyview input configuration. I am thinking that the AV5000 is actually generating the tone, not the Skyview. If that works you can then delete the display widget from the engine screens (100% 50% and 20% sizes) Do a backup first and also make a note about the specific input it is on. You can add it back if needed.

I forgot to mention that I have the earlier Dynon 180. I think the audio comes via the auto pilot or hsi.
