I've been watching a few more of this guy's videos and I'm starting to wonder if an AoA indicator would be useful also on a bog standard, non-STOL equipped, C172 or PA28. The price of the basic kit seems reasonable.

Does anyone here us one? What do you think about it? Is there a hassle, including lots of expensive paper work, to get an installation approved?

I fly a PtF aeroplane (which only requires 20% MTOW paperwork to fly rather than the 100% of a CofA aeroplane) and have considered getting one of these devices. It would help both for strip flying and would be interesting in aerobatics. Now I have more time on the aeroplane I reckon I have a good seat of the pants feel for AoA/stall approaching so I probably wouldn't be any better with one to help me. However in a 182 flying in Alaska with unpredictable winds etc, I can see it being an incredibly useful device. You could loose your entire panel on an approach to a 700' long strip and still land successfully on just an AoA indicator.

I'm not sure an AoA would make that much difference from a STOL point of view. In terms of paperwork, tale a look at CS-STAN to see how easy it is (probably easier than fitting one to a permit aircraft).

Doesn't everybody do this?

Not on every flight. Once I was told that the aircraft I was renting had a u/s stall warning (it had been working the previous time I'd flown it and was working again the next time) - I wouldn't have known if I hadn't been told (I don't recall whether the "being told" was verbally and/or in the paperwork, but I knew one way or the other).

I also stall in various loading conditions. (Strangely, some pax enjoy it. Need to do it at MAUM annually anyway).


Stall warner testing both on and off in all configs is part of the LAA flight test every annual on ours. We regularly check it anyway as its simply a metal tab in leading edge of wing that can get bent slightly. we have about an 5-8 knot warning before actual stall. not a lot of margin but good when you need to land short !

A member of our Strut has fitted one (apparently off-the-shelf item from US) to his Europa, and finds it very useful

Surely you should be eyes out during final, not eyes in the cockpit looking at an AoA gauge? Maybe what's needed is some sort of audible warning, a buzzer or something, when a certain AoA has been exceeded. Has anyone thought of that?

Many AoAs are mounted on the coaming so you can look out, and see the AoA. There's often some kind of audio included, my BK KLR10 announces 'too slow, too slow*'

Toblerone.

It was a bit of a tongue in cheek comment about those who say of GPS or traffic, "You should be looking out"

Mine just make a very loud buzzing sound and doesn't have a visual indication... ;-)
