by its arm. (Moment divided by the constant
1000
is used in
this handbook to simplify balance calculations by reduc-
ing the number of digits.)
Center of Gravity is the point at which an airplane, or
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.
Center of Gravity
Arm
is the arm obtained by adding the
airplane's individual moments and dividing the sum by
the total weight.
Center of Gravity Limits are the extreme center of gravity
locations within which the airplane must be operated at a
given weight.
Standard Empty Weight is the weight of a standard air-
plane, including unusable fuel, full operating fluids and
full engine oil.
Basic Empty Basic Empty Weight is the standard empty weight plus the
Weight weight of optional equipment. .

Useful Load is the difference between ramp weight and the
basic empty weight.
Maximum Ramp Weight is the maximum weight approved
for ground maneuver. (It includes the weight of start, taxi
and runup fuel.)
Maximum Takeoff Weight is the maximum weight ap-
proved for the start of the takeoff run.
Maximum Landing Weight is the maximum weight ap-
proved for the landing touchdown.
Tare is the weight of chocks, blocks, stands, etc. used when
weighing an airplane; and is inCluded in the scale read-
ings. Tare is deducted from the scale reading to obtain the
actual (net) airplane weight.
