Angle of Attach Indicator - AOA

[Vref]

Thanks Ross, it reminds me too much at the times (late nineties) I was in Toulouse France with Airbus enjoying the food and wine (canard a l'orange) during my training...;-)

Ross, as I said, some of the resistance to AOA in the cockpit is ancestor worship, but, for a stabilized approach in a high-inertia machine with computer-derived real-time gross weight computation, it's been shown that the precision of multiple ASI's that read to-the-knot are very effective and sufficient.  (Possibly more so than AOA in that specific flight regime.)  Now, if performing a full-power go around to escape a micro-burst downdraft, an AOA indicator would be a great asset.

Another way to look at it is that the landing flare in an airliner is almost imperceptible--just a degree or two.  In a fighter it's much greater.  The airliner is highly AOA-sensitive, the fighter much less so.   So for the former, delta KTS/delta AOA is high, and ASI is a good metric; in the latter it's low, and AOA is the better metric. 

Personally, I think AOA would be a valuable instrument in the airline cockpit, but apparently inertia and conservatism hold sway.  I have a friend who is a Boeing test pilot.  I'll ask his opinion and post his thoughts.

Thanks Dick, I get what you're saying now. I was not looking at it as a one or the other situation. But I see for a long, gentle, constant rate approach an ASI would provide all information needed.

I vote for a flux capacitor in the extra spot to go back in time at 88 knots.  make sure your ADF works, so you can use "the range"...  without Mr. Fusion, that ADF will help you find some lightning to power your flux capacitor too!  Henseforth abreviated as XC, because every well known and used instrument needs a cool abreviation.  I think Garmin makes one.  Just the right size to take the place of a AOA indicator.  The GXC 1.21 it's called.  Too bad F-18's can't fly 88 knots.  Such a waste.

What is the SA (standard acronym) for that?

I think the old timey approach of  "use the instuments your Grand Pappy used and if you can't hack it, train, train, train and train some more" has been tried and not so true. People still stall and crash and people still overrun runways. I think mental math in the cockpit is a bad idea. It may be nessecary at times, but still a bad idea.

I think it's time to let technology help. I want an AOA indicator in my plane. It's on the short list, but... I don't want to go first. Please, if anybody out there has one installed in a Mooney, or is about to have one installed, give us all a PIREP!

I have a lift reserve indicator installed in my SeaRey (I got it at OSH last summer).  It is much less expensive but it works great.  I would consider it for the Mooney but I don't like the indicator enough.

Your restatement is accurate.  Sorry if I wasn't clear.  If you have a steam gauge panel, it would be just fine but I guess I'm getting a little vain about the look of my panel.  Here are a couple pictures of it installed in my glare shield of my SeaRey where it is very easy to monitor on final approach.

[Shadrach]

I would be fine with that on the glare shield tucked up next to the A-pillar.

I'm putting one in, along with new paint, o/h mags, tires, windows, and a new baby in the middle of the project, so eta to flight status is unknown.

 I can fly by the numbers, but, anything to keep me (and family) a tad safer, in the critical phases of flight is worth it, and they're not that much (in aviation dollars)
