WEIGHT AND BALANCE TERMINOLOGY

Reference Reference Datum is an imaginary vertical plane from
Datum which all horizontal distances are measured for
balance purposes.
Station Station is a location along the airplane fuselage given
in terms of the distance from the reference datum.
Arm Arm is the horizontal distance from the reference
datum to the center of gravity (C.G.) of an item.
Moment Moment is the product of the weight of an item
multiplied by its arm. (Moment divided by the constant
1000 is used in this POH/AFM to simplify balance
calculations by reducing the number of digits.)
Center of Center of Gravity is the point at which an airplane, or
Gravity (C.G.) equipment, would balance if suspended. Its distance
from the reference datum is found by dividing the total
moment by the total weight of the airplane.
C.G. Arm Center of Gravity Arm is the arm obtained by adding
the airplane's individual moments and dividing the sum
by the total weight.
C.G. Limits Center of Gravity Limits are the extreme center of
gravity locations within which the airplane must be
operated at a given weight.
Standard Standard Empty Weight is the weight of a standard
Empty Weight airplane, including unusable fuel, full operating fluids
and full engine oil.
Basic Empty Basic Empty Weight is the standard empty weight
Weight plus the weight of optional equipment.
Useful Load Useful Load is the difference between ramp weight
and the basic empty weight.
