1.12.4. Weight and Balance
Reference
Datum (RD)
An imaginary vertical plane from which all horizontal
distances for
the center of gravity calculations are
measured.
Lever arm
The horizontal distance from the reference datum to the center of
gravity (of a component).
Moment
The weight of a component multiplied by its lever
arm.
Sta
tion
A defined point along the longitudinal axis which is
generally
presented as a specific distance from the
reference datum.
Center of gravity (
C.G.)
Point
of equilibrium for the airplane weight.
C.G.
position
Distance from the reference datum to the CG. It is
determined by
dividing the total moment (sum of the
individual moments) by the
total weight.
Center of Gravity
Limits
The CG range within which an
airplane with a given
weight must
be operated.
Usable Fuel
The amount of fuel available for the flight plan
calculation.
Unusable Fuel
The amount of fuel remaining in the tank, which
cannot be safely
used in flight.
Empty Weight
Weight of the airplane
including unusable fuel, all
operating fluids
and maximum amount of oil
.
Useful Load
The difference between take
-off weight and empty weight.
MTOW
Maximum Take
-Off Weight:
Maximum weight permissible for take-
