Stall Warning Devices.

[djmc4344]

Been thinking about putting some sort of stall warning device on my model IV. Acs has one called the ACI. Anybody have any opinion on this device or any others? I kinada miss the horn blaring away on the landing flare in the old 152 and 172's.

Thanks

I really like the AOA indicator and warning on my Dynon, it give progressive information as you approach stall. Probably not much help if you don't have a Dynon to begin with.

I used the Lift reserve indicator when I was flying my 5. My brother and I have the digital verion in the RV-9A. It is a bit pricey but good. When I was flying the kitfox I paid attention to the needle on base to final turn. You lose a lot of lift in that condition. No wonder there is so many accidents. The digital version has a beeper at stall. The LRI is far left in the First picture and the digital above the efis on the second picture.

Just an opinion - an accurate, progressive, angle of attack indicator gives the most direct indication of what is going on if a person is relying on an instrument's feedback.

Another opinion - A stall horn like what we have on the Cessnas tells us something - but they can be different from plane to plane. A stall horn that goes off too soon is just plain annoying and doesn't help that much.

Stick and rudder skills, practiced well and often are what a person needs to do whether guided by an instrument or not. Another excuse to fly......

There is certainly no substitute for knowing your plane and under normal circumstance that should be enough. The audible warning gives me some comfort that if something highly distracting is going on, (why isn't my engine running, why is there smoke in the cockpit, why are those cheerleaders sunbathing topples down there) I will still be warned of an impending stall.

Certainly won't argue with that, those are words to live by, literally.
