PILOT'S LOADING GUIDE
LOADING
CALCULWTION PROCEDURE
Proper loading of the aircraft is essential for maximum flight performance and
safety. This section will assist you in determining whether the aircraft loading
schedule is within the approved weight and center-of-gravity limits.
To figure an actual loading problem for your aircraft, proceed as follows:
Step
I.
Refer to the latest entry on page
6-6
for the current empty weight
and moment.

problems,
Step
2:
Note the pilot's weight end the position his seat will occupy in
flight
Find this weight on the

scale of the !Loading Computation Graph (page
6-
I)
and cross the graph horizontally io the graph for
#9
and
#2
seats Whe~
!his point is located, drop down
to
the bottom scale lo find %he value of the
moment/1000 due to the pilot's weight and seat position
Repeal the procedure for the
co-pilot and enter these weights and
mo-
mentIlOO0 values in the proper subcolumns in the Problem Form on page
6-7.
Step
3:
Proceed as in Step 2 to account for the passengers in seats
3
and
4.
Enter the weight and value of momentl4OOO in the proper columns.
Step 4:
Again proceed as in Step
2
to account for the amount of fuel car-
ried, and enter the weight and moment11000 values in the proper columns.
Step
5:
Once more proceed as in Step 2 to account for the baggage to be
carried and enter the figures in the proper columns.
Step
6:
Total the weight columns. This total must be 2740 Pounds(1243
kG)
or less.
Total the Moment11000 column.
DO NOT
FORGET
TO SUBTRACT
NEGATIVE NUMBERS.
Step
7:
Refer to the Center-of-Gravity Moment Envelope (page
6-8).
Locate
the loaded weight of your airplane on the left scale of the graph and trace a
line horizontally to the right. Locate the total
moment/1000 value for your
airplane on the bottom scale of the graph and trace
a
line vertically above
this point until the horizontal line for weight is intersected. If the point of inter-
section is within the shaded area, your aircraft loading is acceptable. If the
