  • Flying from Oulu (EFOU) to Raahe (EFRH) to do some touch and go landings. Weather reports were not showing strong gusts, but after getting to Raahe airfield I found out that the wind is gusty and had to do several go arounds before actually getting to do some touch and go landings that I was planning to do.

    Good job. There is an old tailwheel technique for longitudinal alignment that would help you, I think, both with lining up and with gust spread problems. Once lined up on final, we no longer want to turn so no need for aileron and adverse yaw. The gust causes relative wind differences on just one wing and therefore bank that results in a bit of heading change. The Cherokee has a spring connect between aileron and rudder, but the spring allows a bit of delay. When we use the yoke for aileron bank to return the down wing back up, unless we lead rudder for correct yaw the nose will yaw in the direction of the down wing and the down aileron there which is bringing in both back and up. That bringing the wing back, as the down aileron causes greater lift on its wing, is the incorrect yaw problem. At altitude we don't notice the nose going the wrong way initially and we just step on the ball to bring coordination. On final, especially on short final, the nose going the wrong way is very disconcerting.
    So there is a solution to coordination, lead rudder rather than wait and step on the ball. There is also a solution to incorrect yaw longitudinal alignment problems, don't use any aileron at all. If we walk the rudder dynamically and proactively, same as riding a bike or balancing a broom on our hand, to exactly bracket the centerline tightly, we not only nail longitudinal alignment but also keep the wing level. If we do not allow the nose to either turn or yaw well away from the target (centerline), we do not allow the wing to bank. So now we have not only solved the alignment problem, the adverse yaw, but we also have solved the gust putting a wing down problem. If we are walking the rudder pedals to keep the target exactly between our legs, the wing cannot get down even if gusts try to move it down.
    So try this. You will like it. And no more wing wagging on short final where we get especially concerned with going down the centerline. I even have a student put his hands in his lap and thus force proper rudder yaw. Rudder yaw is how we get correct alignment, not turning.

      Thanks, I will try that. I know that I still have some issues of not applying rudder at the same time when I use aileron, especially in cases where a sudden gust, turbulence or wind shear lifts one wing in level flight and that is one thing I try to learn.
      In this flight the wind was almost directly from the side, so I had to keep my wind side wing down and correct the sideways slip that the wind causes that way. So when a wing lifted due to a gust (I think it was more of a wind shear btw, but I used term gust in the video because most people won't understand the difference between those two), I wanted to correct for that so that the wind side wing stays down, but not too much.
      I think I understood what you meant though, instead of correcting that using ailerons, just use rudder and it will bring down the wing also, so I'll try that next time I'm flying :). Actually I'm due for a check ride, so I'll ask my flight instructor for a comment also.
