He has a much better feel for his airplane than I do for mine -- if I'm *wearing a noise canceling headset I can't hear OR FEEL (caps intentional) some of his landings when the mains touch the surface. I know we're down when he lowers the nose wheel, *I tell him it's easier in a high wing airplane, but later I went out in the M20 alone and did 5 touch and goes, and felt the mains touch down each time. It's going to take some work to get the rate of descent close to zero at an altitude of an inch or so. For the record, my new friend did not land hot -- the stall warning was chirping. Anyhow, he can 'grease it on' better than anyone I know. Ideas on technique to do that are welcome. Yeah, other than practice practice practice I suggest you need to try aim to hold off only 6" above the runway until the plane won't stay off. I suspect you are just too high/slow in your roundout/flare. By the way, I don't close the throttle slowly, I closed it completely as soon as soon as I've committed to the landing -otherwise I go to full power as I know I'm going around to try again. With an instructor, try flying the plane down the the runway at just 6" altitude with say 1700 RPM (your instructor should know the throttle setting for this exercise). It will get you the picture and teach the more delicate touch you need (it worked for me). Also the 'perfect' landing starts on final, you must _nail_ speed and profile early (not late final) and the plane should fly all the way down with almost no adjustments -use the trim and you should be almost hands off all the way down. All the way down final, keep saying AIRSPEED, AIM, ATTITUDE and get them right. Finally, get used to braking as this needs practice too. Good luck. |

Yeah, other than practice practice practice Actually, practice is the answer as opposed to defining any one thing that constitutes a good landing. One of the first things I do with a new instructor is to get them thinking in terms of teaching flying as a constantly changing dynamic as opposed to reducing things down to common denominators where "doing this accomplishes that". I think it's human nature to attempt to define one act or action that stands out above all others to make defining a complex act more simple to understand. A certain amount of this in flying is acceptable, but the better approach I think is to define all flying as doing whatever is necessary based on constant motion in a constantly changing 3 dimensional environment to put the airplane where it has to be at any given moment in time. This is especially true of landings, where the aircraft is being operated in that constantly changing environment to ever decreasing error correction parameters. Dudley Henriques Next time I do this, it'll be called *touch and goes but I'm going to try to not touch -- maintain landing attitude and speed, low but not touching for a couple of thousand feet along the runway. I'd think the ground effect in the Mooney would make a gentle touch down easier, ground effect induced lift increases pretty quickly as the wing to ground spacing gets small. I remember now that my friend was glancing to the side as opposed to looking ahead, that contributed to his sense how high he was. *When I've committed to touching down I'm more apt to be looking at the centerline and the turn off, what's to the immediate side doesn't matter as much. In terms of visceral sensations, his really greased on touchdowns were delicious. He, like me, tended to hold whatever backpressure he had at touchdown until the nose wheel made contact with the runway. A nicer touch might be to relax some of that pressure until the nose wheel was close, then increase it again to reduce its rate of descent. It would be really neat, but unimportant, to get all of the wheels rolling without the usual sensation of touching down. What you are describing, holding the airplane off just short of touching down, is a very good practice procedure that I used all the time. One thing that will help you tremendously is to taxi into position on an uncontrolled runway somewhere where you can relax for a moment in position. Make sure your seat height is correct and relaxed and that you are sitting in your normal flying position. Take a moment and just LOOK ahead of the aircraft and to each side diagonally through the bottom of the windshield. Make a mental note of these visual cues. They ARE your touchdown cues! On all your landings, don't fixate on any one cue but keep your eyes moving all the time scanning forward and back on the runway. Match your control pressure input in all axis to your "touchdown" visual cue, and you have the makings of a good landing. The Mooney sits low so you might have a tendency to flare a bit high but recheck those "touchdown visual cues" on each and every takeoff and I think you'll be surprised at how much better your landings will become as you unconsciously match those cues on each landing you make. DH For the most part I can put the airplane down pretty much where I want to: what I was shown is the softest "greased - on" landings I'd seen. I will work on those, but I'm not sure taking cues from beside the airplane is a good idea: my guess is just when you're looking to the side is when a deer will decide the grass is greener on the other side of the runway. As someone else mentioned, the low wing Mooney, especially when landed with full flaps, likes to float, so energy/speed control is pretty critical -- get close to flare altitude 5 knots fast and you've just lengthened flare to stop distance by 500 feet or more. I think very smooth landings in the M20 would best be done with minimal flaps -- that trapped air under the wings and ahead of the flaps just has no place to go! In really short field practice I know the center of lift really moves aft with full flaps -- and for short fields I like to bring the flaps up in the very late flare to get weight on the gear as soon as possible. As they go up I need increasing back pressure because the center of lift moves forward. It is kind of fun to have the tail skid be the first thing that touches down No, that should only happen in a tail dragger during a 3 point. You need to fix that error. Cheers |

It doesn't happen often, but if I need a minimal ground roll I get behind the power curve, hang that sucker by its prop, minimum air speed, and the skid is going to touch down first. It lands at a very slow speed over the ground, and can be stopped will short of the book distance. Don't try this at home, this demonstration is being done by an expert* under carefully controlled conditions (smile). I have not landed the Mooney on a soft field, but given at normal rolling attitude the prop can be a weed whacker, I'd do the same thing then. There are times when an excessive nose up attitude landing is good airmanship (groundsmanship? and if I screw up a landing in that way I can call it practice, can't I?). *expert, best understood by taking the word apart.An ex is a has been, a spurt is a drip under pressure. |

I'm assuming you know this already but I'll throw it out there just as a general comment. Landing behind the curve can indeed be done but within a VERY strict area of the backside curve. You have to keep the aircraft from sliding too far behind the curve into the area where power alone isn't enough to hold the altitude or sink rate. In fighters we call this the "coffin corner", and it's not related to the common reference that usually defines "coffin corner" at altitude. Coffin corner in this context defines the line on the curve where you've run out of available power and now HAVE to decrease the angle of attack to either hold the altitude or stop the sink. No room to decrease the AOA and you're in a world of hurt! This is a much misunderstood area of performance when pilots start discussing landings behind the curve. In other words, you can drag it in behind the curve and plonk it down, but ONLY TO A POINT behind the curve. It's a dangerous practice and I would never recommend doing it to pilots who's skill levels were unknown to me personally. Dudley Henriques |

I will work on those, but I'm not sure taking cues from beside the airplane is a good idea: my guess is just when you're looking to the side is when a deer will decide the grass is greener on the other side of the runway. As someone else mentioned, the low wing Mooney, especially when landed with full flaps, likes to float, so energy/speed control is pretty critical -- get close to flare altitude 5 knots fast and you've just lengthened flare to stop distance by 500 feet or more. I think very smooth landings in the M20 would best be done with minimal flaps -- that trapped air under the wings and ahead of the flaps just has no place to go! In really short field practice I know the center of lift really moves aft with full flaps -- and for short fields I like to bring the flaps up in the very late flare to get weight on the gear as soon as possible. As they go up I need increasing back pressure because the center of lift moves forward. It is kind of fun to have the tail skid be the first thing that touches down No, that should only happen in a tail dragger during a 3 point. *You need to fix that error. Cheers We're going to disagree, Flaps. It doesn't happen often, but if I need a minimal ground roll I get behind the power curve, hang that sucker by its prop, minimum air speed, and the skid is going to touch down first. It lands at a very slow speed over the ground, and can be stopped will short of the book distance. Don't try this at home, this demonstration is being done by an expert* under carefully controlled conditions (smile). I have not landed the Mooney on a soft field, but given at normal rolling attitude the prop can be a weed whacker, I'd do the same thing then.

I'm assuming you know this already but I'll throw it out there just as a general comment. Landing behind the curve can indeed be done but within a VERY strict area of the backside curve. You have to keep the aircraft from sliding too far behind the curve into the area where power alone isn't enough to hold the altitude or sink rate. In fighters we call this the "coffin corner", and it's not related to the common reference that usually defines "coffin corner" at altitude. Coffin corner in this context defines the line on the curve where you've run out of available power and now HAVE to decrease the angle of attack to either hold the altitude or stop the sink. No room to decrease the AOA and you're in a world of hurt! This is a much misunderstood area of performance when pilots start discussing landings behind the curve. In other words, you can drag it in behind the curve and plonk it down, but ONLY TO A POINT behind the curve. It's a dangerous practice and I would never recommend doing it to pilots who's skill levels were unknown to me personally. Dudley Henriques In my case I have a few thousand hours in the airplane and know its habits well (except in terms of having the sink rate only inches a minute at touchdown) , and the few times I carry power into the landing it really isn't much -- at even 2100 RPMs in slow flight the Mooney has a pretty extreme nose up attitude. I can appreciate your concern and am sensitive to the issues. I understand. Sounds like a Mk21? DH |

One of the first things I do with a new instructor is to get them thinking in terms of teaching flying as a constantly changing dynamic as opposed to reducing things down to common denominators where "doing this accomplishes that". I think it's human nature to attempt to define one act or action that stands out above all others to make defining a complex act more simple to understand. A certain amount of this in flying is acceptable, but the better approach I think is to define all flying as doing whatever is necessary based on constant motion in a constantly changing 3 dimensional environment to put the airplane where it has to be at any given moment in time. This is especially true of landings, where the aircraft is being operated in that constantly changing environment to ever decreasing error correction parameters. Dudley Henriques Next time I do this, it'll be called *touch and goes but I'm going to try to not touch -- maintain landing attitude and speed, low but not touching for a couple of thousand feet along the runway. I'd think the ground effect in the Mooney would make a gentle touch down easier, ground effect induced lift increases pretty quickly as the wing to ground spacing gets small. I remember now that my friend was glancing to the side as opposed to looking ahead, that contributed to his sense how high he was. *When I've committed to touching down I'm more apt to be looking at the centerline and the turn off, what's to the immediate side doesn't matter as much. In terms of visceral sensations, his really greased on touchdowns were delicious. He, like me, tended to hold whatever backpressure he had at touchdown until the nose wheel made contact with the runway.. A nicer touch might be to relax some of that pressure until the nose wheel was close, then increase it again to reduce its rate of descent.. It would be really neat, but unimportant, to get all of the wheels rolling without the usual sensation of touching down. What you are describing, holding the airplane off just short of touching down, is a very good practice procedure that I used all the time. One thing that will help you tremendously is to taxi into position on an uncontrolled runway somewhere where you can relax for a moment in position. Make sure your seat height is correct and relaxed and that you are sitting in your normal flying position. Take a moment and just LOOK ahead of the aircraft and to each side diagonally through the bottom of the windshield. Make a mental note of these visual cues. They ARE your touchdown cues! On all your landings, don't fixate on any one cue but keep your eyes moving all the time scanning forward and back on the runway. Match your control pressure input in all axis to your "touchdown" visual cue, and you have the makings of a good landing.

Love the pushrod linkages between the cockpit and the control surfaces. The downside of the airplane is draining fuel when it's raining (most times I am wearing a suit -- that I both sail and play golf means I have the vocabulary for draining fuel after someone did not replace the fuel caps correctly. It's also a chore getting into the airplane more or less dry when it's raining. and blowing. But once inside? Well, Mooney pilots do smile a lot even if the tail is on backwards. |
