Refers to the direction from the nose to the tail of the aircraft; it is the axis around which roll occurs.

Refers to the vertical axis of the aircraft; it is the axis around which pitch occurs.

Refers to the direction from wingtip to wingtip of the aircraft; it is the axis around which yaw occurs.

Refers to the overall length of the aircraft; it is the measurement from the nose to the tail.

The upward or downward movement of an aircraft’s nose around its lateral axis, controlled by the elevator on the tail.

The side-to-side movement of an aircraft’s nose around its vertical axis, controlled by the ailerons.

The forward or backward movement of an aircraft’s nose around its longitudinal axis, controlled by the rudder.

The rotation of an aircraft around its center of gravity, controlled by the flaps.

Hinged parts on the back edge of wings that increase lift or drag, helping planes take off and land more safely.
