Arm:
The horizontal distance expressed in inches from the reference datum plane to
the (CG) of an item or location along the fuselage.
Units of measurements and weights must be consistent for each set of
calculations and in the same system of units, i.e., pounds and inches,
or kilograms and centimeters.
Moment:
The product of the weight of an item multiplied by its arm.
(Weight x Arm = Moment)
Installed Equipment:
All optional accessories and equipment permanently installed
on an airframe or engine at the time of weighing. These items must be included in
the “Installed Equipment List.” Additions and deletions must be noted in the list each
time they are made and new Weight and Balance calculations performed to
determine the magnitude and effect of weight change. Ballast, if permanently
installed, must also be listed.
Ballast:
A specific amount of weight attached in a specific location, which can be
temporarily or permanently installed in an aircraft, to help bring its (CG) within the
required limits. If temporary ballast must be used for certain operations, the exact
amount and its location must be placarded on the instrument panel within clear view
of the pilot. The use of Ballast increases Empty Weight and reduces Useful Load.
Loading Chart:
Used to calculate the actual (CG) location of a ready to fly aircraft.
Care must be taken not to exceed the Maximum/Minimum Weight and Balance
Limits stipulated for the aircraft. These limits are determined by structural, stability
and control considerations throughout the aircraft speed range.
PROCEDURE
All permanent equipment, options, and accessories should be installed on the
aircraft prior to weighing. All equipment options and accessories installed in the
aircraft must be listed on the “Installed Equipment List”. That list becomes part of
Weight and Balance Documents.
Be sure to remove any loose equipment, tools, etc. from the aircraft prior to
weighing.
Sometimes it may be necessary to adjust or reduce fuel, cargo, or passenger
weights to remain at or below Maximum Allowable Gross Weight. Temporary or
permanent ballast is sometimes necessary to bring the CG within specified limits.
