writes: Every plane I've ever flown has a mechanical stall warning device (some visual, some aural), but apparantly it's possible to certify a plane without one. Does anybody know of any real life examples of planes certified without stall warning devices? The IAI 1124 Westwind jet I fly does not have any stall warning devices installed. I have not taken it to a full stall and break, but it does give plenty of warning, via buffeting, of an impending stall. G. Lee (If it ain't broke, don't fix it. If it ain't fixed, don't fly it.) |

The Citabria I learned to fly on (7ECA) was licensed under the same certificate as the 7AC, and it didn't have a stall warning device. They are certified, of course, but very few of the 25,000 homebuilts in the US have mechanical stall warning systems. Of course, the bracing wires of my Fly Baby sing "Nearer My God to Thee" when I get too slow.... :-) Ron Wanttaja |

Does anybody know of any real life examples of planes
certified without stall warning devices? Aeronca Champ 7CCM---so much as they are not "airplanes" I've not yet seen a sailplane with a stall warning device. Funny, considering how much time we spend banked to 45 degrees or more just above stall. Oh that's right, we become "one" with the plane, don't need no stinken stall warning. Mac |

It has automatic leading edge slats which will pop out at larger angels of attack, but you are still well above stall. A power off stall is very interesting in this aircraft. You start to get stall buffett and, if you simply hold the yoke all the way back, you descend a little over 1000 fpm with the nose level on the horizon. You can turn with just the ailerons as you are descending. What happens if you yank the sitck back? Or if you start to apply rudder to accelerate a turn and then apply opposite aileron to keep from banking too steeply and just keep on crossing the controls while you bleed off airspeed? Just curious. I'm sure the results in the Socata are benign. Don I've gotten a slight stall break in a 3/4 power on stall. Very benign with a slight fall off to the right which was easily countered with ruddder. With full power and no flaps, I've approached stall buffet, but at that point I was more than 30 degrees nose high and felt like I was going to tumble out of my seat backwards. And, at the onset of stall buffet, I was still climbing! The Rallye is a STOL aircraft with oversized control surfaces and Fowler flaps. I have done turns starting from a maximum forward slip and didn't notice any adverse behavior, but I was probably 10 knots above stall. I've done 45 degree banked turns at MCA and found the aircraft handling to be smooth and solid. One of my partners has gone to 60 degrees bank at MCA and said he had the same results. -- Marty Shapiro Silicon Rallye Inc. (remove SPAMNOT to email me) |

Now that I think about it, I've flown a Decathlon. I honestly don't remember if it had a stall warning or not. My recollection is you knew you were stalled when you saw the ground going round-and-round :-) The Navion is CAR 3. Dunno about the Maule. |

The Cessna 501 and 551 (better known as the Citation I SP and II SP) meet
part 25 requirements, but are placed under part 23 for single pilot operations. They have no stall warning devices. There is a very significant prestall buffet. -- Larry Fransson Seattle, WA |

My Tri-Pacer had none.

Whole bunches of early machines don't have them including (but not limited
to Piper Cub series Taylorcraft BC-12D Pitts Special P-51 Mustang Corsair Spitfire The Falco had an aerodynamic rather than mechanical. There's a false leading edge on about 6 inches of the wing which causes turbulent air over that section and makes a buffeting on the wing to give the indication of an impending stall. I personally haven't flown an airplane with a stall warning in about 250 hours (last 5 years or so) and, quite frankly, would rather do without the racket. Shawn "Roy Smith" wrote in message ...
