Have you flown any aircraft that does not have one?
 
Learned to fly in a Cessna 120 that didn't have one that I recall.Other aircraft without one would be a Thorp T-18, Pitts, and my E-AB LSA. Don't remember hearing one in the Taylorcraft I did my last flight review in.
 
I got my private in a T-Craft that had no stall warning system. Not that it needed it. You pretty much knew it was about to stall from the buffeting.
 
Ok Big shot

You should be able to feel a stall long before that horn goes off. You should also be able to still fly the plane with that horn going off.


And to answer the OP, yes.

None of the gliders I have flown have a stall horn/light/buzzer etc. Just the guy in the seat.
 
Both my Glasair & Velocity have no stall horn or light. No AOA indicator either. Oh the humanity! :)
 
Yes. Most of my time is in airplanes without mechanical/electrical stall warning devices.

I think a different question is "Have you ever been surprised by a mechanical/electrical stall warning device warning?" In other words, have you ever been saved by such a warning? We can assume that the stall warning devices, in those airplanes so equipped, were announcing stalls in the stall/spin crashes we all read about and regret. How many of us are here because a stall warning alerted us to save the day?

I don't know that it saved the day - probably just saved me from unexpected excitement - but I was practicing steep turns in a C-152 one day when I got the stall warning to buzz a couple times to let me know I was getting near an accelerated stall.

Yeah they have gone off and no. I knew what the airplane was doing with or without the buzzers or lights.
 
None, nada, stall warnings in the following airplanes I've owned. 2 Taylorcrafts, two 140 cessnas, 1942 Stearman, piper cub, Cessna 195, aeronca 7bcm champ. Yes, the previous post is correct. The fellow who said " if your familiar with the airplane, you know when it's near a stall" especially true in a Stearman as the rigging has a distinct sound as it nears a stall. They all do to a lesser degree. I had to learn stall -spin recovery in a champ when I got my private. It makes you realize, dramatically, that proper speed is imperative when in a pattern or anytime your near the ground. If you stall in a pattern, most likely you will die. I will add that after glancing at the Asi on downwind, I usually don't look at it again. Also rented a 150 hp Citabria a lot before being forced to go light sport. Same, no stall warning.

Sailplanes, parachutes, cubs, helicopters-there is rotor rpm warnings so maybe those don't count. I've flown sailplanes with no stall warning and no asi - it ain't hard if you have a brain. Course if you are all scared up with fear limiting mental power you need all the help you can get.
 
Transitioned at ~15 hours from a 150 to a Citabria without mechanical stall warning. Flown ~700 hours in various Fly Babies that don't have one, either. Though the wind in the landing wires is a pretty good cue.

The Navion has no stall warning horn or light but it passes the certification requirements in that it has a pronounced buffet heading into the stall (and the stall is real docile after that).
 
No stall warning device on the Apache I last flew. The buffet tells you everything you need to know.
 
Recent airline accident in Clarence, n.y. Had stall warning plus stick shaker, still reacted wrong, killed 56 people. ( as I recall, the mooney 201 I flew a lot had one but on final it was more of a distraction than anything else. It frightened my wife as it started long before the airplane stalled on landing.

Almost every stall warning device can be adjusted to go off prior to the stall.

If it doesn't contact your A&P and get it fixed.

In the 150 i fly it goes off just 2-3 seconds before the stall and I can normally feel it well before that.
 
Maybe the better question is: Everything fails. Do you know how your airplane feels well enough not to count on a warning device? :)

Stall warning devices are not calibrated by time in seconds.

It's speed thing.:)
 
I have not, but learning in a DA-20 taught me to ignore it, damn thing isn't adjustable and goes off way too early.

No **** huh? DA-40s do the same thing, they are however adjustable....;) with tape, you can bring down the upper 'lip' of the opening in the wing to get the horn sound at the correct AoA that you want, I typically try to get it right at 5 kts before stall. Then take a small scribe and mark that level at the edges of the hole so you can quickly reset your tape during your next preflight. I like using white medical tape for that.
 
Quite a few aircraft. My Flybaby being one of them.
 
My Eagle does not have one. I usually don't stall whan I come over the numbers to land at 110 mph.
 
Most '48 170s don't have one, but you probably know that already.

IIRC, the stall warning wasn't required until B model when they significantly changed the wing.

I don't think I have ever had a stall warning go off that I wasn't expecting with the possible exception of hearing brief chirps in really rough air.
 
There are a million airplanes that don't have stall warning systems. OP - are there any points of discussion you're interested in? We could go on and on listing airplanes that don't have stall warning.

But do you come in at 110 because you're afraid of stalling? Seems pretty fast. What does your Eagle stall at power off?

Thing about biplanes is they slow down really fast lol.

The OP is TomD......

Try to guess where he wants this thread to head..;):wink2:...........:lol:

Yep, you can even do it Sean Tucker style - come in around 140, throw the prop in, wheel it on about 120, ride the brakes and keep the tail up with smoke on as you come to a stop 3000' later. :D

Tom, aren't at least stall warning devices a crude angle of attack indicator? If they were based simply on speed, they wouldn't go off in an accelerated stall.

Also, please note the image below from a Cessna.

Confirming my supposition, I ran into this comment from you:

That really depends upon what systen you have.

If you have a vane style that has a little stickey out on the wing, AOA blows the vane up to close a switch and sound the horn.

If you have a Cessna with the tweeter style it is nothing more than the reed from a baby doll that has air sucked thru it, and out thru the vent on the wing by changing AOA.
(found this after I made my post)
