5.5 FLIGHT PLANNING EXAMPLE
(a) Aircraft loading
The first step in planning a flight is to calculate the airplane
weight and center of gravity by utilizing the information provided
by Section 6 (Weight and Balance) of this handbook.
The basic empty weight for the airplane as licensed at the
factory has been entered in Figure 6-7. If any alterations to the
airplane have been made affecting weight and balance, refer to
the aircraft logbook and Weight and Balance Record (Figure 6-9)
to determine the current basic empty weight of the airplane.
Use the Weight and Balance Loading Form (Figure 6-13) and
the C.G. Range and Weight graph (Figure 6-17) to determine the
total weight of the airplane and the center of gravity position.
After proper utilization of the information provided, the
following weights are to be considered in the flight planning
example.
The landing weight cannot be determined until the weight of
the fuel to be used has been established [refer to item (g) (1)].
(1) Basic Empty Weight
1144 lbs.
(2) Occupants (2 x 170 lbs.)
340 lbs.
(3) Baggage and Cargo
0 lbs.
(4) Fuel (6 lb/gal x 30)
180 lbs.
(5) Takeoff Weight
1664 lbs.
(6) Landing Weight
(a)(5) minus (g)(l), (1664 lbs.
minus 99.9 lbs.)
1564.1 lbs.
The takeoff weight is below the maximum of 1670 lbs. and the
weight and balance calculations have determined the C.G.
position is within the approved limits.
