G-10. Loading data (Figure G-5). The loading data illustrations provide information necessary to work a loading
problem for the aircraft. The balance computer, if furnished, accomplishes the same purpose and requires less
computation. From the loading graphs or tables, weight and moment/constant are obtained for all variable load items
and are added arithmetically to the current basic weight and moment/constant (from DD Form 365-3) to obtain the
gross weight and moment. The center of gravity of the loaded aircraft is represented by the intersection of the gross
weight and moment lines on the center of gravity graph or by a moment figure if tables are used. If the aircraft is
loaded within the forward and aft center of gravity limits, the intersection will fall between the limiting center of gravity
lines on the center of gravity graph, or if a table is used, the moment figure will fall numerically between the limiting
moments. The effect of the center of gravity on the expenditures in flight of such items as fuel and expendable stores
may be checked by subtracting the weights and moments of such items from the takeoff gross weight and moment
and replotting on the cneter of gravity graph or by checking the new moment with the center of gravity table. This
check should be made to determine whether or not the center of gravity will remain within limits during the entire flight.
NOTE
U.S. Army Special Mission Aircraft shall use DD Form 365-4 titled TRANSPORT.
G-11. Weight and Balance Clearance Form F, DD Form 365-4 (Figure G-6). Form F is the summary of the actual
disposition of load in the aircraft. It records the balance status of the aircraft step by step. It serves as a work sheet
on which the weight and balance technical records and calculations, and any corrections, must be made to insure
that the aircraft will be within weight and center of gravity limits. It is necessary to accomplish Form F prior to flight
whenever an aircraft is loaded in a manner for which no previous valid Form F is available. Form F is furnished in
expendable pads, or as separate sheets, which can be replaced when exhausted. An original and a carbon copy
are prepared for each loading. The original sheets, carrying the signature of responsibility, can be removed to
serve as certificates of proper weight and balance as required by existing clearance directives. The carbon copy
must remain in the aircraft for the duration of the flight. On a cross-country flight, this form aids the weight and
balance technician at refueling bases and stopover stations. There are two versions of this form: TRANSPORT and
TACTICAL. They were designed to provide for the respective loading arrangements of these two types of aircraft.
It will be noted that the general use and fulfillment of either version is the same, although specific instructions for
filling out each version are given in the -10 manual. The choice of which version to use in case of a tactical aircraft
which is used to transport cargo items, or of a cargo ship which is armed for protection, is the responsibility of the
weight and balance technicians at the takeoff base.
