The Dutch roll of an aeroplane is felt most strongly

  • A.Equally everywhere
  • B.At the rear of the cabin, furthest from the centre of gravity
  • C.At the centre of gravity, where the lateral acceleration is greatest
  • D.On the flight deck only

Answer: B

The yaw component gives a lateral displacement proportional to the distance from the centre of gravity, so the motion is worst at the extremities, and the rear cabin is the longest arm on most transports. That is why ride-quality complaints come from the back and why the flight deck can report the same oscillation as mild. At the centre of gravity the yaw contributes almost no lateral translation at all. The flight deck feels it, but less, and no aeroplane feels it equally throughout.
