:) Well this is a clear indication that you don't understand AOA. It wouldn't be useful IN THE SPIN, it would be useful on RECOVERY.
Perhaps if one wants to pull out on the verge of an accelerated stall, but airspeed + G meter would be more tight on the scan plus looking outside. Most aerobats know about it, could use it, and the planes I've flown are still not retrofit. Maybe I could put a bit of yarn on the side of the fuselage, glider-style. :p

Ronald Reagan:There You Go Again - YouTube Stop with the "you just don't understand" and provide a convincing scenario or argument for the implentation. I'm not negative about AOA at all, and I understand it well. I'm just not a fanatic about proselytizing its use for all GA aircraft. It is bordering on crazytown.

Otherwise - I will gladly agree to disagree with you on this issue and we'll go our own ways.
We are not fighter pilots on verge of accelerated stalls, nor airliners near the coffin corner. I get the feeling you're arguing something just because you feel you have to be on "team AOA!!!" and hence your repeated misrepresentation of my position. |

I still don't see exactly how you will think it is used on a routine GA flight, or how you estimate the advantages outweigh the costs of install that others have pointed out. The last thing a pilot needs is another gauge that sits there in the green arc, as rickair and I pointed out, I already know I'm within the envelope.
In the training environment, it's likely that it wouldn't just "sit there in the green arc". Don't you think it would be a great training aid to provide new pilots a better understanding of the whole concept? (especially an accelerated stall) |
If I remember my spin training AOA breaking would be the first indication that you have broken the stall, isn't that a good thing? The AOA guage is simply a visual cue to confirm your tactile feel.
What cardio is arguing is a chicken and the egg, he doesn't think they are useful because no one is trained on them. No one is trained on them because they aren't widely available. I am sure Wilbur and Orville had a similar discussion on the benefit of a slip indictor. What do I need that string for? That is essentially what AOA is is a slip indicator in another axis. |

Seriously, flying has a thinking side to it that AoA represents an essential part of and as a subject matter it is both fascinating and rewarding. The theory runs deep on this, well into high college level courses like low and high speed aerodynamics, aeroelasticity, aircraft design and optimization, hydrodynamics, flight dynamics, simulator design, computer flight modeling, model aircraft, glider and helicopter design, engine design, aerobatic and military flight, so many high level topics. To put one small instrument in the cockpit is not asking much if you are aware of how many things are dependent on it. It may not be required to watch AoA in some aircraft, but it matters in all aircraft whether the pilot thinks about what's going on or doesn't. |
As all 4 of my children have proven many times, any 6 year old can fly an airplane straight and level at cruise. It's when you slow down and start turning that it gets interesting.
That happens mostly on approach and landing, but also on a turning departure, which is also where most accidents happen. That's exactly where I've found the AOA most useful. In a light airplane that has an AOA, I almost never even look at the airspeed when turning base and final, I'm looking at my aim point on the runway, looking for traffic on long final (uncontrolled airport) and I'm cross checking the AOA as I slow and configure. In a light G/A aircraft (any single engine prop) you can pretty much feel when you are getting too slow/too high AOA, as the elevator gets heavier in the turn. I once delivered a Piper Cub from PA to FL with no airspeed indicator, due to water in the system. 6 landings with no airspeed indication, but in a Cub, the AOA indicator is the open door, when it lifts up, you need to unload it! It's the larger/heavier jets with no real feedback through the flight control system that can benefit most with an AOA. I don't know how you guys were first taught to fly, but my IP never mentioned airspeed in my early lessons, he mentioned "Feel", as in, "Feel that? It's sinking!" When I go out in a new (to me) airplane, one that I've never flown before, usually solo, I fist go out and practice slow flight. Not all the way to a full stall, but just close enough to get the feel of it when it's slow. Once you develop the feel, you really don't need an airspeed indicator for pattern work. You'd be much better off to keep your eyes outside, looking for traffic if you are at an uncontrolled field on any weekend! |
I agree with your post Timbo. I learned to fly the same way. I have also flown/delivered a few airplanes without airspeed indication. Unfortunately not enough folks learn to fly that way anymore. I FEEL... this might be a sizeable component of the current LOC issue. I am now in favor of the AOA use in general aviation and especially as a training aid. Though it will also better prepare those who go forth to fly aircraft where it's use would be more beneficial or even considered imperative.

Having a good feel for the plane prevents you from doing all sorts of horrible things and is essential for good VFR flying. In fact I would say that is the one thing that makes you from a standard pilot to a great, safe pilot.
How is AOA better than ASI for routine non-accelerated/non-high G and non high-altitude flight? It's not. Essentially same information. Everybody wants to have the next whiz-bang stall/spin protection device. In a few years some will say synthetic vision is required to prevent CFIT. I understand and recognize its use but I don't need it now. Here is a typical stall/spin accident from a few months ago, unfortunately fatal. Look at the attitude, power, airspeed (AOA surrogate) during the entire event. PLANE CRASH FROM INSIDE COCKPIT Money retrofitting planes with AOA trinkets would be better spent on instilling better basic airmanship for most GA guys. The two pilots did a lot of obvious things wrong, and having yet another gauge screaming at them would be unlikely to prevent the incident. |
You win we are all idiots and bow to your superior knowledge about airmanship and training.
No one is saying make it mandatory, they are saying it is a very useful instrument and can help train ham fists to recognize when the wing is operating efficiently and when it is not. When operating a high performance aircraft on the edge of its performance envelope you do not look at the AOA indicator. You do however spend time before that training to know what the aircraft feels like at particular AOA settings. |

I can tell you though that I wish I had an AoA gauge in every aircraft I fly - and if I owned (especially at today's costs) it would be one of the first things I'd have in my plane - - sort of like that tornado shelter I put in my house! :D

http://turbineair.com/wp-content/upl...speed-2013.pdf I don't care, if any of you want to spend the money and put in an AOA gauge in your plane go right ahead. I'm just trying to have a civil discussion to make sure that you and I are making good decisions.

Turns are accelerations.
Would AOA gauge be a useful addition for training? Sure. Understanding AOA can be accomplished without this and these are pretty fundamental concepts. |
