Names For The Axes of Vehicles
Air vehicles use a coordinate system of axes to help name important parameters used in the analysis of stability. All the axes run through the center of gravity (called the "CG"):
- "X" or "x" axis runs from back to front along the body, called the Roll Axis.
- "Y" or "y" axis runs left to right along the wing, called the Pitch Axis.
- "Z" or "z" runs from top to bottom, called the Yaw Axis.
Two slightly different alignments of these axes are used depending on the situation: "Body-fixed Axes", and "Stability Axes".

Famous quotes containing the words names, axes and/or vehicles:
“Ideas about life organize perception; names of emotions organize sensations; rules of syntax organize thought. But pain comes on its own.”
—Mason Cooley (b. 1927)
“Henothing common did, or mean,
Upon the memorable Scene:
But with his keener Eye
The Axes edge did try:”
—Andrew Marvell (1621–1678)
“Television programming for children need not be saccharine or insipid in order to give to violence its proper balance in the scheme of things.... But as an endless diet for the sake of excitement and sensation in stories whose plots are vehicles for killing and torture and little more, it is not healthy for young children. Unfamiliar as yet with the full story of human response, they are being misled when they are offered perversion before they have fully learned what is sound.”
—Dorothy H. Cohen (20th century)
