Stall warning. In or Out?

[jcbarker]

Just started the QB assy instructions. One of the first things is build and install the stall warning system. Hmm. Got me to thinking. Do I really need that? I didn't have one in my -8. Used AOA. I quickly discovered that I never looked at my airspeed indicator once I was below flap speed in the pattern.
Any other thoughts on this?

Don’t install it; it isn’t necessary, especially with aoa. In the first time you walk into that stall vane, you’ll wish you hadn’t installed it!

On the other hand I like mine. If I end up a bit high and slow it gently reminds me..... And when doing slow maneuvers at altitude same thing.... I did wire it into the G3X and didn't have a separate board or system for it.

Just curious - do you have the AoA on the G3X installed and calibrated (and audio connected)?

I don’t have stall warning vanes on any of my planes because I have AoA (with audio) - which is far better than a discrete “you’re about to stall” because it shows (and tells) you where you are in the AoA regime.

I agree, you don’t need the stall vane once your aoa is working and calibrated. I installed it anyway, just in case I had first flight(s) difficulties before the aoa was calibrated.
But also, I ‘trust but verify’ - I would never deliberately make a landing approach without checking the airspeed indicator as well as the aoa.

I don't hear audio from the AOA, but it is calibrated. I hear other G3X alerts. Maybe I'm missing out!

For me AOA with audio is the best VFR avionic tool I have. Being able to hear when you start to encroach on a stall is priceless. Trying to watch AOA I think would be distracting but then again I have never done this. If I don't hear a light beep on touch-down I know I was to fast. I also compare AOA to TAS and can tell exactly what my touchdown airspeed was. I know hours is not an indication of potential wear on our tires but at this point I would bet I will get well over 600 hours on a set of tires. Having the lowest controllable airspeed when landing I think a part of the equation. I have also found that if you smell rubber on touchdown, you were probably going too fast. AOA is also a great teaching aid for optimum landing speeds.

And no I did not install the stall warning vane. (Vans also will not let you delete this, if you've bent yours let me know, I have spares).

Thank you all for your input. I'm going with AOA only. I'm going to plug those holes with a couple of AN426AD3-3 rivets and move on.

I'd say install it. It's a redundant single-point AOA warning.

We installed it, and the reason was that the early test flights wont have the AoA calibrated. That stall warner tho... she just works.
