Default AOA display

I agree with those that think the AOA instrument is very useful, however, like others have said, I'd love for it to be on the glare shield instead of in the panel. I'm flying behind the legacy Dynon's and I believe there's a thread somewhere where Brian or someone made a device to do just that. This thread just got me thinking about it again. Guess I'll go see if I can find it.

Default Synthetic AoA

Paul,

Did I read somewhere that you were testing a synthetic AoA that didn't require the pressure ports to give a pretty good indicator of actual AoA? Perhaps I was dreaming, but if this was something real, it could be a great addition to GA aircraft without the plumbing requirement.

Regards, Mickey

I always chuckle when I see how unassuming and down-to-earth Paul is about his former day job, but his modesty has never induced me to under-appreciate his valuable insights. ("Hypersonic Glider"! I can imaging a day coming down the road when some young buck won't know what he's alluding to here!)

Ditto. Some earlier post within the last few years on this same topic sold me thoroughly. As a long-time but still low-time pilot, I'm convinced AOA is the single best insurance I can buy to help me fly my creation safely. In fact, my AOA system is literally the first piece of panel kit I ever bought!

I am not looking at my instruments for the majority of of the traffic pattern. I would find an audio-only AOA to be as valuable as an audio-visual AOA and more valuable then a display-only AOA.

Default My .02

I'm with Glen here, and I know this is going to be controversial, especially with the likes of Paul having a different opinion, which I respect and hold in the highest honor. That being said, the traffic pattern or final is nowhere to have our heads inside the cockpit, and there is already way too much of that going on. I'm sorry, but if we are operating these RV's that close to the edge, than something is wrong. This dependency on automation has empirically caused a documented deterioration of basic airmanship within the airline industry. Perhaps an audio warning system is appropriate for the times you might get distracted by an airplane on the runway, someone cutting in front of you, ATC instructions, or the myriad of other distractions that can happen in the traffic pattern. But to be chasing the AOA or airspeed, as happens when people begin to start relying on them as opposed to "attention grabbers" when needed is way over-kill for our aircraft in normal situations.
Now AOA useage while out doing aerobatics or for instructing what the airplane feels like and helping someone understand how far you can push the airplane, or in an emergency engine out situation, that's great, and I am in full support.
I promise I won't conintue with my opinion here, but wanted to get it out there.
Thanks for listening.

Vic

Default FAA/AOPA Committee Pushes AOA

Even a Cessna 150's stall is not like that of a Cherokee. That's how I saw my first spin as pilot in command. The instructors liked to fly the Cherokee which was air conditioned and I'd fly the 150 solo because it was cheaper. I was shown the accelerated stall in the Cherokee and tried to duplicate it later in the 150. As the stall horn started to chirp, I noticed that I was holding right aileron in a left turn (I later figured out this was because the instructor was not in the other seat) which meant it would break into the turn, not out of the turn as I was expecting. I decided to roll out and rethink things, but got sloppy with the rudder and the next thing I knew, I was in a power-on spin. I knew how to recover from flying RC models and I'd been through numerous spins with a friend in his J-3, so I got out of it pretty quickly, but it took about half an hour of flying around before I was calmed down enough to attempt a landing.

Default Audible

Glen,
The Dynon is audible, when properly hooked up, and there may be some settings that I haven't investigated yet, but right now mine alerts me on the last yellow bar, I think. She has a nice voice!!!!

I would still like to see it on the glareshield though for more precise alerts. I'm pretty sure there isn't any difference in the Dynon voice as you get closer to the actual stall.

I'll take that challenge. I just received my Dynon pitot tube today, and I'm planning on using the G3X. However, I'm just on my first wing right now, so it'll be a while.

Default AFS AOA Pro

...in my panel for the last nine years. Left side up top so I can keep its massive disply easily in my peripheral vision on the 180* decending turn to final. I have this routine of 1) eyeballs out 90% of the time with a 2) quick glance at the AOA (5%) and 3) quick glance at airspeed (5%). Rinse and repeat. Over time I developed a feel for the procedure and kinda know what the AOA is going to be showing (if the fuel state, baggage and DA aren't too out of whack). Move any/all of those variables up very far and the AOA will really surprise you with its reading.....like at the end of a return from OSH (low fuel, big bags, hot day).

If it broke today I'd order another one tomorrow.



Another, slightly larger image from a different angle:

An older picture of my panel but the AOA is still in the same location, she also yells: "ANGLE ANGLE PUSH PUSH" in my ear when I get to slow.
