Anyone flown with an AoA indicator?

Was reading an article in an Australian mag about an LED based AoA indicator
in a homebuilt. The author stated that in many ways it "replaced" the AI for
him.

Anyone have experience with them?

xerj,

Yes, but only a few times, and far better than an asi (not ai -
attitude indicator). Very easy to use and I found that pilots I flew
with were much less likely to carry too much speed on final approach, a
common cause of landing accidents. I like them a lot.

It's no wonder the Navy uses them for all landings.

All the best,
Rick

Woops. Yup -- you knew what I meant.

I'd love to have a play around with one, experimenting with the various V
speeds and such. I'm sure it would be a good training device.

More than a training device, it's a true real world device in that you
don't have to adjust speeds for weight, the AOA indicator does it for
you. Simplifies life a great deal.

All the best,
Rick

Used them many times. If I had to choose only one instrument to have in my
airplane it would be an AOA indicator.
In the T38 you have a choice in how to land the airplane. You can fly the
approach at 155kts plus fuel [1kt per 100lbs 1000lbs remaining]
OR, you can fly the AOA indexer. Optimum AOA for approach in the T38 [
..6alpha on the indicator or donut on speed] will automatically produce the
right approach speed for the GW.
Works the same way in the ole' puddle jumper as well :-)
Simple!

So I gotta ask...why aren't they standard equipment?

Wouldn't it be a good thing to get another form of reference when learning
slow flilght / stalls / approach to land?

FWIW, I've flown lots of F16 hours on my PC and an AOA indexer makes the
relationship between pitch and power very easy to see and understand.

Probably the most unique AoA indicator I ever saw was in Nebraska on a
homebuilt. Don't know what the aircraft was...open cockpit, high wing,
looked like a bathtub with wings and engine in back....and out on the
left strut attached with a pivot point was a crescent shaped piece of
painted aluminum that had its narrow edge pointed forward. There was a
90deg bend at the very top of the crescent to catch the wind not unlike
some stall indicators. On the face of the crescent, visable to the
pilot, were painted segments that read, "Not Enough - Just Right - Too
Much".
I still laugh at the simplicity of it!

One of our club planes had a "Lift Reserve Indicator" (which is a
combination of angle of attack and snake-oil, I think). I never got a
chance to play with it, because most people hated it and had it ripped
out.

In my opinion yes.

AOA is optional equipment for GA and I understand the airlines have done a
study on it's use in large aircraft.
Some of the airlines have integrated an AOA indicator into their MFD's as an
add on option.
The Air Force has never really been a huge fan of AOA on approach, but the
Navy uses it because their approach is backside and has to be completely
stabilized to the deck.
As far as I know, Boeing has done a study on it and submitted the results to
the airlines.

Most of us joining PanAm during, or just after Vietnam, had considerable
experience flying AOA and couldn't understand why the latest jetliners
were not so equipped. It soon became obvious that ALPA and the old WWII
bomber captains that it represented wanted nothing to do with modern
technology. This group rejected CVRs, GPWS, AOA and anything else that
would have required them to be retrained.

This group of pilots are held in high esteem by almost everyone except
those of us who had to fly with them. They had received minimal training
for their B-17 or C-47 job in the Airforce and only through the strength
of the union, barely made it through the jet transition.

They still (1960's) would fly a "raw data" ILS instead of using the flight
director. Most of them had no business in a jet airplane. PanAm crashed
a large number of their B-707s due to pilot issues.
