The Aircraft Owners and Pilot’s association conducted a survey amongst themselves to see what technique they most commonly used to land in a crosswind. The results were anonymous, and this brings us to the third and final method: The Decrab!

My reasoning to do this in two parts is largely due to the composition of the decrab method. It’s a combination of both a crab and a slip, therefore requiring the pilot to have mastered both before attempting to combine them in practicing the decrab method.

HOW IT’S DONE

  • A crab is utilized all the way down to approximately (5 – 10ft) or (1 – 3m).
  • Let the airplane weather-vane into the wind and use heading to correct for ground track.
  • This keeps your passengers comfortable and minimizes your chances of having to have the aircrafts interiors steam-cleaned after landing…
  • Once we get down to the transition altitude mentioned above, we smoothly transition the aircraft from the crab to a slip.

  • Use rudder to align the vertical axis (yaw) with the centerline of the runway and hold it aligned using the rudder.
  • Correct the aircraft’s drift (left and right) using aileron.
  • This should result in the upwind wing being low and having opposite rudder applied.
  • Holding the slipping corrections in place and adjusting for the wind can be challenging. Each time the winds change, so do our correction inputs.
  • The goal is to land the aircraft on the upwind (lowered) wheel first, then slowly the downwind wheel, and then finally the nose.
  • AIRCRAFT LIMITATIONS

    All airplanes have limitations, and it’s your job as its pilot to know what they are. With enough of a crosswind, an airplane will eventually “run out of rudder.” This just implies that even with a full rudder deflection, there still isn’t enough input to keep the aircraft aligned with the centerline of the runway. Be sure to reference the aircraft’s POH for limitation information.

    So what can you do if the winds are outside of your comfort level? Another perfectly acceptable course of action is to divert to an airport with a runway more favorably aligned with the wind. If you don’t feel comfortable, then this is the safest course of action. Don’t ever be ashamed to do this. Remember to always set your own personal minimums and always have a plan B… and C… and D… and enough fuel to achieve them, if needed.

    Once again, I encourage you all to go crank up the simulator winds and give this a shot.  Let me know how it goes! Until then…
