Dynon Angle of Attack

[kmach]

Hi,
I have the Dynon D-100, as of yet I did not do the AOA calibration/setup. I am planning on setting it up, have the calibration instructions in my flight bag !
I was not in a big rush to do it, My thoughts were that it might be too much info /clutter at certain times. although you can turn the AOA display in the EFIS on or off. I should get it setup/calibrated at the least.

I like Dorsal's setup with audio "chirps" , I get an audio warning from the D-120 when engine parameters are not within the set numbers, now I am wondering if I will get the chirps from the AOA, hhhmm ? some more testing in the future !

For those of you who like to tinker (AKA save money), I have seen the AOA tubes fabricated and attached directly below the Pitot tube. Many of the guy's over on our "sister ship site" (Van's Airforce) have quite a bit to say about how the AOA works out with the Dynon. From what I have gathered the "angle of the dangle" if you will, can be made to work bending this extra tube anywhere around 45 to 60 degrees. Then following the Dynon AOA calibration instructions...they are said to work well. I look forward to toying with this in the future.

Thanks for the responses. I feel better now and will go ahead with the Dynon AOA. I like Dorsal's setup with the sound so you don't have to be looking down at the panel during the very busy landing approach. It seems like a good system for maximizing short field landings; you can approach close to stall angle like Navy carrier pilots do, without having to watch airspeed gauge.

I went to the Van's Airforce forums and searched for Dynon AOA and found a lot of comments and information. Thanks Dan for the suggestion. It was nearly all good and the calibration seemed easy. Most agreed that it was not very useable if the audio warnings were not enabled. Flying a consistent AOA approach at about 5 mph above stall seemed to be a common way of using it.

Unfortunately I belive you will need a separate audio feed from the D100. I also have a separate efis and ems and though linked by dsab they have independent audio.

Everything I've read suggests that any AOA or Lift Reserve instrument really should be a stand alone display with large lights or dial right at the top of your panel, so it is easy to see in your peripheral vision. Not sure if an AOA bug on an EFIS would be as easy for your eye to acquire, particularly on a flare or if things started getting busy like Bruce said.

That's why the audio link for the Dynon is so important.

I'll be putting (probably) a D180 in Smitty's plane and will utilize this option for sure.

Agree, I almost never look at the indicator but always know where I am relative to the stall on touch down (and other maneuvers at the edge).

Yep, in my RV I mounted the AFS one in a small fiberglass fairing on the top of the glareshield. It stood up like a shark fin. I could turn off all the panel lights, and do night landings with just that row of LED's. Love AOA!

Looks nice Andy!
