On Nov 23, 11:43*am, a wrote: The thing you may be missing is you are used to flying a certain glide slope, probably defined by the VASI. On a short field for me at least the final approach over the obstruction to flare is MUCH steeper. I'm trading off comfort and some margin for a very short roll-out. I bet you are right on what I am used to for glide. *Instrument world does make a mess of visual approaches and it's nuances. Generally I don't miss the VASI or PAPI, as that is how I learned ) keeping the bug spot on the numbers), but what I haven't had much practice "for real reasons" is that 50 foot obtacle clearance. Imaginary trees not quite as "intimidating" when the real deal trees tend to block the lights at approach end of the runway on a low glide path. :-) and I really didn't feel that low coming into M23 as I would have made the runway (without the trees) *had the fan quit. *The last short field airport I went to was 2700 foot and it was much easier since there were no obstacles. So in a nutshell, short fields I can hang with, it's that extra variable having trees :-) that give it a little extra slam dunking challenge for me. I can pretty much assure you if you get slow with a steep approach angle the trees will be less a mind games problem. Come in at a steeper approach angle, aim for touchdown 1200 feet short of the turnoff -- you'll be surprised at how easy the short field technique is. 2700 feet is simply not a short field, I'd be aiming to touch down 1500 feet from the turn off in a routine landing. If you go slower in effect you'll be flying an approach angle a 172 with some flaps deployed flies, and if it feels dicey the first couple of times there's plenty of room for pitching down a bit. Try it at 2000 feet agl, get a bit slower, then watch airspeed and rate of descent. You're apt to be surprised at how comfortable you'd be at something a lot more than 3 degrees. A final not-in-the-book technique is to carry a bit of a slip down the center line -- much easier if there's a cross wind -- but the Mooney, normally a very clean airplane, turns into a pig when flown a bit sideways. All of this, of course, assumes one is very familiar with the airplane. I am very comfortable closer to the edge in my airplane than I would be in something like a 172, which is a much more forgiving airplane, unless I had a bunch of recent hours in it. I would not do any of the things I mentioned with a non pilot aboard, and even with one who's not a CFI I'd be doing a lot of talking to avoid having the right hand seat badly stained. After all, I have to get out of the airplane over that seat. Had a thought -- be fun to do some of those things with some of the pseudo pilots who post here aboard. My pre flight check list would include the challenge "Depends?" with the required response "On". |

Try this: get the nose way up and add say 1/2 power. You've trimmed for airspeed now with this high attitude so control airspeed with power and aim point with elevator. You'll be amazed at your approach angle in this very high drag config. If the stall peeps just open the throttle a bit and keep that aim point fixed all the way down. Get used to flying on the throttle with almost second by second subtle power changes. Now you drop speed by reducing throttle on very short final to say 10k over Vs. As you round out/flare you will shed energy very fast as you simultaneously chop the throttle - you should be less than 3' AGL. The plane will settle firmly onto the mains in a _very_ high nose angle but that's what you want -all the weight on the mains and no energy left. Lots of drag is here to slow you down: The wing really is deeply stalled. Nose super high adding fuse drag Lots of elevator trying to keep nose wheel off (the elevator should end up all the way back -adding even more drag) With all weight on the mains make those wheels squeal (but don't lock up)! The nose wheel only touches when YOU can't keep it off but don't relax that back elevator -think drag and weight on the mains. When you do this a few times you will realize that all sorts of new places are potential landing spots. If you are not comfortable with the backside of the power curve practice this type of descent at altitude and note the VSI. Gradually get lower as you get used to the method and the way your baby responds to throttle. I'm not an instructor so I could be talking rubbish (perhaps I'm not a real pilot ;-) One last thing: I learnt from tail dragging -the landing is NOT over 'til the plane is stopped. YMMV Cheers I think your second sentence is the answer, NOT the first one to correcting the problem I encountered in the video. *Problem as I replied to A was that I was intimidated by the real deal 50 foot obstacle (AKA trees) causing me to make a steeper then normal descent. I plan to go back and try this again to keep practicing :-) |

The more weight the more effective are the brakes. In the end, we may be talking talking about a difference of 10 or 20 feet in rollout one way or the other. For what it's worth, powered slow flight deep in the flare ALWAYS drags the Mooney's tail skid, then that contact pitches the mains down very firmly! It feels as if it's dropped on from a foot above the runway. I'd rather land with the nose still coming up with some elevator left, but on the other hand never had land off field. I suppose if some condition forced that I'd do what I had practiced rather than experiment with something else. The theme of this thread has changed into encouraging us all to do that practice. You hinted at tail dragger experience so you would NOT be welcome to take part in that short field hamburger bet I mentioned earlier unless your taildragger is a DC 3. . It would be a lot easier just to send you a gift certificate to Ruby Tuesday's. |

Initiatially the aerodynamic factoers are more important, but keeping the nose wheel off for as long as possible maximizes braking. Then again I would bow to higher authority. The more weight the more effective are the brakes. In the end, we may be talking talking about a difference of 10 or 20 feet in rollout one way or the other.

It feels as if it's dropped on from a foot above the runway. I'd rather land with the nose still coming up with some elevator left, but on the other hand never had land off field. OK. An additional factor is on a rough field the nose wheel is a weak point so keeping it off may prevent firewall damage. I suppose if some condition forced that I'd do what I had practiced rather than experiment with something else. *The theme of this thread has changed into encouraging us all to do that practice. As I see it, being good at short field is a good idea. The iron fairey can quit at any time... Being able to drop the plane into a small area adds a lot to my confidence... You hinted at tail dragger experience so you would NOT be welcome to take part in that short field hamburger bet I *mentioned earlier unless your taildragger is a DC 3. . It would be a lot easier just to send you a gift certificate to Ruby Tuesday's. AlI can say is that tail dragging turned my landings from average into much better than that. I recommend it! Cheers |
