True, it is just the wing that is stalling. No, it's not. You can't get the angle of attack required to stall the wing without hitting the tail. You somehow seem to think that you can let the airplane down more gradually using elevator while at a higher speed than what occurs when the wing stalls. This simply isn't the case in most airplanes. Bull**** -- that's *exactly* what you are doing. It is obvious that you weren't taught full-stall landings No, I was taught by instructors who were educated enough to know what they were actually doing.

If the stall horn is on only a second before touchdown, you have not stalled the airplane. The stall horn sounds well before you reach the stalling angle of attack. True, but only a few knots above in the Cessna's I've flown 150 - 182. If you keep smoothly pulling back the yoke, the airspeed will bleed into stall territory very shortly after you get a full stall horn. Matt |

I get enough angle of attack that the wing will no longer support the weight of the aircraft even with full up elevator. I'm not sure your definition of stall, but this one works for me.

Bull**** -- that's *exactly* what you are doing. Yes, I'm using the elevator to bleed off airspeed until the wing will no longer support the airplane. That isn't quite the same as using power and pitch when "flying onto" the runway. The wing will still support the weight of the airplane in that approach so you are flying it onto the ground. It is obvious that you weren't taught full-stall landings No, I was taught by instructors who were educated enough to know what they were actually doing. How many of your instructors have been appeared in AOPA Pilot's Pilot feature? Matt |

... True, but only a few knots above in the Cessna's I've flown 150 - 182. Per certification rules, the stall warning must occur AT LEAST 5 knots prior to stall. In my experience, it commonly occurs with an even greater margin. If you keep smoothly pulling back the yoke, the airspeed will bleed into stall territory very shortly after you get a full stall horn. No, it won't. The airplane will settle onto the runway before you stall. You have to move the yoke pretty sharply to keep lift equal to weight at that airspeed. Pete |

... I get enough angle of attack that the wing will no longer support the weight of the aircraft even with full up elevator. Any angle of attack may be insufficient to support the weight of the airplane. All you need is a low enough airspeed. I'm not sure your definition of stall, but this one works for me. The definition of stall is quite different, and has already been discussed in detail in this thread. Bottom line: you don't define stall based on the lift the wing is generating. You *may* relate stall to (but not definite it based on) the coefficient of lift, but to figure out actual lift you need to account for airspeed, and stall has nothing to do with airspeed, not from a definition point of view. Yes, I'm using the elevator to bleed off airspeed until the wing will no longer support the airplane. That does not mean you are stalling the airplane. It just means your angle of attack is insufficient to generate lift equal to the weight of the airplane at your current airspeed. Pete |

In my experience, it commonly occurs with an even greater margin. I think 5 is considered "a few" by most, even hair-splitters such as yourself. If you keep smoothly pulling back the yoke, the airspeed will bleed into stall territory very shortly after you get a full stall horn. No, it won't. The airplane will settle onto the runway before you stall. You have to move the yoke pretty sharply to keep lift equal to weight at that airspeed. Yes, it does require that you accelerate the rearward movement of the yoke as the plane begins to settle in order to hit the stop at or slight before the tires touch. Again, I guess it depends on how you define stall. To me, a stall has occurred when I can't maintain altitude with the elevator full-up. That is the condition in which I attempt to land in normal conditions (light crosswind and lack of significant wind gusts). I've never flown a Cessna with an AOA indicator so I can't say if I've achieved the critical angle of attack prior to touchdown, but these have been called "full stall landings" since before I was born so that is good enough for me.

To me, "a few" is generally three, while I'd use "several" for five or more. In any case, the real question is how much before you stall will the horn go off. It goes off much longer than a second before you stall the wing. [...] but these have been called "full stall landings" since before I was born so that is good enough for me. As long as you understand that you are not actually stalling the airplane, that's fine. Use whatever inaccurate terminology you like. Pete |

If you want someone to interpret your statement of "a few" with other than THEIR definition, you need to be more specific. It is useless to come back later and redefine it for them. As long as you understand that you are not actually stalling the airplane, that's fine. Use whatever inaccurate terminology you like. I understand that I'm stalling the wing, not the airplane. Now you're just being an ass; "stalling the airplane" is the same as "stalling the wing". In any case, you are not stalling the wing either. Pete |
