Stall Warning setup

[Gerhard Rieger]

Hi to all, have any of you installed a stall warning system on your aircraft?

[jaredyates]

Several of he EFIS packages include a stall warning aural alert. The Bearhawk is a very predictable airplane as it approaches the stall, and whether or not there is a separate warning device, and there are certainly plenty of "warnings" that the airplane provides. The noise level gets very low as the airflow around the cabin decreases, the ailerons become less effective, but most reliably, the position of the stick moves aft. I wouldn't go to the trouble to install any type of separate warning system, but if you are using an avionics package that already includes it, you might as well try setting it up to see if you like it. But the Bearhawk is a very low-threat airplane when it comes to stalls.

Thanks Jared, no flying four place Bearhawk’s in SA, all I have is the forum and the expertise from you all.

I am not installing a stall warning device but did elect to install an Angle of Attack pitot tube which allows a nice display on my Garmin panel. Fly like the Navy!

I agree AOA is a fancy upgrade.

I installed a Dynon Pitot that included AOA. It's very impressive - I only really use the aural functionality and have never looked at the visual guidance. I like that it accounts for increased weight and load factor. For example, in a steep turn it starts beeping at a higher speed based on approaching the stall AOA.

The technology of our day allow so much more than what we are used to, I myself have never used any of them, I went old school with all my systems. The radios, navigation and GPS will all be up to date and new. Thanks for all the great info. Maybe one day I will go the glass cockpit way.

Gerhard: I built this very system a year ago. It works great. Not knowing what wing you have but I will make this statement: My LSA Riblett airfoil required a higher position on the leading edge to obtain the correct stall warning. Stinger

That system works very well - effectively an AOA warning system. I used to fly a small fleet of Grumman AA5's that had them. The advantage is that like the AOA warnings and being activated by the high AOA, they take into account weight, loading etc. We used to teach Max Rate turns by rolling into the turn and pulling "back stick", using the elevators as a sort of "off/on" switch to activate the AOA warning. Worked really well.

[Gerhard Rieger]

Stinger, I just followed the instructions to find the upper and lower point, adjustments will be required when we test fly it. Nev, I am used to this system and its good to hear of more benefits. Thanks for your input

The AOA is almost a free upgrade with the new systems. So why not. The autopilots almost so. Just the cost of the servos as all the capabilities are built into the Garmin panel.

[Gerhard Rieger]

I’d love to add angle of attack .

[BravoGolf]

Perhaps Onspeed would work for you. Runs independently of an EFIS into your audio panel.

I’m also going with a simplistic panel and plan on installing the onspeed system

[Gerhard Rieger]

I will look into it, thanks

Same here, I had it in the Garmin version in the last plane I was flying, no need to look at it, just listen

Same here, two servos and you have full autopilot
