Normally, these axes are represented by the letters X, Y and Z in order to compare them with some reference frame, usually named x, y, z. Normally, this is made in such a way that the X is used for the longitudinal axis, but there are
368:. Performing a rotation in an intrinsic reference frame is equivalent to right-multiplying its characteristic matrix (the matrix that has the vectors of the reference frame as columns) by the matrix of the rotation. 299:. A positive rolling motion lifts the left wing and lowers the right wing. The pilot rolls by increasing the lift on one wing and decreasing it on the other. This changes the bank angle. The 199:, or roll axis â€” an axis drawn through the body of the vehicle from tail to nose in the normal direction of flight, or the direction the pilot faces, similar to a ship's 665: 189:, lateral axis, or pitch axis â€” an axis running from the pilot's left to right in piloted aircraft, and parallel to the wings of a winged aircraft, parallel to the 271:. Pitch changes the vertical direction that the aircraft's nose is pointing (a positive pitching motion raises the nose of the aircraft and lowers the tail). The 99:) about the principal axes.

They are geometrical symmetry axes, regardless of the mass distribution of the aircraft. 186: 179:, or yaw axis â€” an axis drawn from top to bottom, and perpendicular to the other two axes, parallel to the 398: 176: 622:.

In aeronautical and aerospace engineering intrinsic rotations around these axes are often called
