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:
“All nationalisms are at heart deeply concerned with names: with the most immaterial and original human invention. Those who dismiss names as a detail have never been displaced; but the peoples on the peripheries are always being displaced. That is why they insist upon their continuity—their links with their dead and the unborn.”
—John Berger (b. 1926)
“Henothing common did, or mean,
Upon the memorable Scene:
But with his keener Eye
The Axes edge did try:”
—Andrew Marvell (1621–1678)
“Only by the supernatural is a man strong; nothing is so weak as an egotist. Nothing is mightier than we, when we are vehicles of a truth before which the state and the individual are alike ephemeral.”
—Ralph Waldo Emerson (1803–1882)
