Not at all. You come in and level out an inch or less above the runway and then bleed off speed until you stall and settle onto the runway. It is very smooth when done correctly. The plane isn't stalling. George Patterson Why do men's hearts beat faster, knees get weak, throats become dry, and they think irrationally when a woman wears leather clothing? Because she smells like a new truck. |

I do greaser full-stall landings just as I was taught.
I have never seen anyone do a greaser full-stall landing; the two are contradictory. If you have enough speed to grease it on, you're not even close to a stall. Most people rarely do full-stall landings, and nobody I know teaches students to stall the plane in. You touch down with some flying speed. Not at all. You come in and level out an inch or less above the runway and then bleed off speed until you stall and settle onto the runway. It is very smooth when done correctly. Maybe nobody you know does, but R.C. Johnston at N38 taught his students this way for probably 50 years. Talking about taildraggers here? I greased the three-point landing on my check-flight, but rarely since. Even on grass, there's generally a rumble. Perhaps it can be done consistently, but I've never met anyone who does, not even my instructor.

The plane isn't stalling. True, it is just the wing that is stalling. At the onset of stall the airplane will settle very smoothly to the runway assuming that the wheels are very close when the stall occurs. 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. When the wing stalls, the lost of list is fairly dramatic, but it still takes time for the airplane to accelerate downward. If you are within inches of the runway, this will set you onto the ground very gently. Few pilots can do a more gently touchdown using elevator control alone. It is obvious that you weren't taught full-stall landings (by that I mean having the control wheel full-aft and the stall horn blaring at the moment of touchdown) and don't know how they are done or how good the results can be when done properly. You should find an instructor competent in this area and take a lesson or two. It will be both fun and enlightening. Matt |

Dick could do them very consistently, but then he probably averaged 20+ landings per day for something close to 50 years. He's retired now, but still flies his 150 for fun. I can't do them consistently, but probably hit what I'd call a greaser about 40% of the time. Most folks I've flown with or watched, don't do greasers any more than that during a "flown on" landing. I didn't say it was EASY to do full-stall greasers, I just said it was possible. I believe the OP asserted it wasn't possible. That is simply not true. Matt |

... True, it is just the wing that is stalling. At the onset of stall the airplane will settle very smoothly to the runway assuming that the wheels are very close when the stall occurs. You really should have gone and read this whole thread before reviving it. This trail has been worn quite smooth already, and you're on the wrong side of correctness with respect to the possibility of a literal "full-stall landing". 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. When the wing stalls, the lost of list is fairly dramatic, but it still takes time for the airplane to accelerate downward. If you are within inches of the runway, this will set you onto the ground very gently. Few pilots can do a more gently touchdown using elevator control alone. You cannot achieve a pitch angle sufficient to stall the wing while "within inches of the runway". The tail of the airplane will hit the ground first. It is obvious that you weren't taught full-stall landings (by that I mean having the control wheel full-aft and the stall horn blaring at the moment of touchdown) and don't know how they are done or how good the results can be when done properly. Obvious? What's obvious is that you are making statements without having the knowledge to back them up. It's also obvious you don't have the good sense to avoid insulting someone else's flying ability without ensuring first that you have a clue about what you're talking about. I can't vouch for George's flying ability, but there's nothing in his posts to suggest it's anything less than stellar. Your denigration of his flying skills was completely unjustified. You should find an instructor competent in this area and take a lesson or two. It will be both fun and enlightening. Take your own advice. Pete |

(Sorry if I missed it earlier in the thread.) Let's consider a 172. I've heard (though I don't know if this is right) that the critical AoA for 172s is somewhere around 15-18 degrees. Looking at the diagram in the POH, I see the wing chord at an angle of about 20 degrees to a line tangent to the underside of the main wheels and the tail. So there seems to be room for a stalled landing--especially if there's flap deployment, which increases the camber and AoA even further. Or am I missing something here? --Gary |

I didn't denigrate his flying skills, simply suggested that there is a skill he wasn't taught. Nothing to be ashamed of about that and it certainly isn't an insult. I wasn't taught to do Immelmanns, and saying I can't do one is hardly an insult, just a fact. You should find an instructor competent in this area and take a lesson or two. It will be both fun and enlightening. Take your own advice. I do at least once a year. Matt |

... Pete, what are the numbers on that? Having accidently scraped the tail on the runway without stalling the airplane, I have emperical evidence of that fact. Keep in mind also that the stalling AOA while in ground effect is not the same as that at altitude. Pete |

Keep in mind also that the stalling AOA while in ground effect is not the same as that at altitude. What aircraft type? Sure, if you fly along low with sufficient airspeed and then yank back on the yoke, I'm not surprised that you could get a tail strike. However, if you fly inches above the runway and hold the plane off as the airspeed decays, you can get the yoke all the way back and the stall horn on just a second before touchdown. I've done it many times and this is the way my instructor taught me to make virtually every landing, even crosswind landings in light winds. Matt |
