All,
Occasionally, I find myself in the following situation when landing. I am trying to figure out what I am doing wrong. I fly over the numbers at the proper airspeed, and on the (VASI) glideslope. I flare by putting the cowling to the horizon and holding off unitl touchdown. After touchdown, I find the plane drifting to the left, while the nose is pointing to the right. Applying further right rudder seems to result in a squirrley/sliding feeling (not sure if I am acutally sliding though, just afraid to push it any further). Applying brakes at anything more than very slight pressure results in skidding. At this point, I find myself rolling down the runway, unable to slow down fast enough and trying to control the drift. This could happen in little to no wind conditions. What am I doing wrong? I'm not a beginner, but occasionally this happens and I can't seem to figure it out. Do I need to.... A. Crank in aggressive alieron to the right. B. Apply lots of back-pressure to get more weight on the mains to allow breaking. C. Something else....? Dan |

After touchdown, I find the plane drifting to the
left, while the nose is pointing to the right. Applying further right rudder seems to result in a squirrley/sliding feeling (not sure if I am acutally sliding though, just afraid to push it any further). Maybe you've picked up some wind. Surface winds are often different from winds even slightly aloft. The plane needs to land straight (so apply LEFT rudder to point the aircraft down the runway). It needs to land with no drift (so apply RIGHT aileron to counteract the drift). It's just regular crosswind correction, but you got surprised by encountering a crosswind on touchdown.

are you always drifting left?
is it always the same airplane? is the gear straight? someone else may have twisted the gear in a landing and the alignment is off is the nose wheel canted to one side? more back pressure will not put more weight on the wheels to stop the skidding with brake application aileron into the wind, not aggressive may help, get to aggressive and depending on the winds/aircraft you could raise one main back off the ground It would not be the best advice to say.. raise the flaps to get more braking effect, but that is the placard in the Beech Sport/Sundowner/Sierra series. Two many people with electric flaps and hydroelectric gear have raised the gear on rollout and not the flaps. Raising Manual Flaps does help to "unload the wing" and get more weight (braking action) on the mains. Always, never touch gear/flap switches until clear of the runway and you can look at what you touch. BT "Dan" wrote in message ups.com...

The drift develops after I touchdown. If I am already drifting left,
left rudder would probably result in running off the runway.... Dan Jose wrote: After touchdown, I find the plane drifting to the left, while the nose is pointing to the right.

It doesn't happen that often, but it did last night. I am trying to
remember if it is always left, and actually I think it is. It is NOT the same airplane. Had the problem in an Archer, Arrow, and Comanche. - probably my technique. Could I be unintentionally doing something with the rudder on touchdown?

Dan If you are drifting left with the nose pointing to the right and the wheels are firmly on the ground, I'd say your nosewheel is getting jammed. |

Dan A disclaimer first, that I'm a post solo student [P S == Post Solo]. I have had similar (opposite) problems after touching down with the nose pointing to the left while the plane drifted to the right. My CFI found two things that I was doing uncontiously. one is the non-level movement of the yoke when applying the back-pressue while rounding out, and in my case, I was over-correcting my earlier tendancy of "pulling the yoke downward" action by raising the left elbow too much. Then stepped on the left rudder in reflex to "correct" that -- resulting in the nose pointing to the left while the plane drifted to the right. Your problem could be the opposite of mine, i.e. your left elbow was pulling down the left alieron, or, maybe as the nose rose, it yawed to the left by the same reason it yawed to the left on takeoff with more power, and you used right rudder to correct it, instead of very slight right alieron in the round out. If the later is true, the wings were not very level before touching down. |

I think you may be on to something here. So, what you are saying is
that in a calm wind, I might be unconciously adding left alieron in the flare, and correcting with right rudder... I think this acutally happens to me _more_ in calm wind situations.

Exactly. Your description of the problem sounded too familiar :-).

I am flaring with my left hand (right hand on the throttle), so
probably crank the yoke to the left a bit... --Dan P S wrote: Exactly. Your description of the problem sounded too familiar :-). Dan wrote: I think you may be on to something here.
