yaw
bullet::::- normal axis, or yaw axis — an axis drawn from top to bottom, and perpendicular to the other two axes. parallel to the "fuselage station".









































bullet::::- transverse axis, lateral axis, or pitch axis — 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 "buttock line".









































bullet::::- longitudinal axis, or roll axis — 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. parallel to the "waterline".
aircraft principal axes
the normal qrs axis is generally "down and to the left", following the anatomical orientation of the heart within the chest. an abnormal axis suggests a change in the physical shape and orientation of the heart or a defect in its conduction system that causes the ventricles to depolarize in an abnormal way.









































the extent of a normal axis can be +90° or 105° depending on the source.
