Describe loading limitations.

Description should include the following:

• The mathematical measure of an aircraft’s tendency to rotate about its CG is called a moment.
• A moment is said to be equal to the product of the force applied and the distance at which the force is applied. (A moment arm is the distance from a datum [reference point or line] to the applied force.)
• For aircraft weight and balance computations, moments are expressed in terms of the distance of the arm times the aircraft’s weight (i.e., inch-pounds).
