Ref 12. Enter sum of the difference between
Ref 10 and Ref 11. Recheck against GROSS
WT. TAKEOFF in LIMITATIONS table to
assure that this figure does not exceed
allowable limit.
Record figures in LIMITATIONS table as fol-
lows: In FORWARD and AFT space for PERMISSI-
BLE C.G. TAKEOFF enter an inches figure
obtained as follows: Match weight figure recorded in
Ref 12 with a corresponding figure in the GROSS
WEIGHT-POUNDS on Center-of-Gravity Limits
Table (Table 6-4). Determine the FORWARD limit
in inches figure for the weight matched and record
in the FORWARD space stated. Enter AFT C.G.
LIMIT in inches in AFT space.
14. Ref 13. By referring to Center-of-Gravity
Limits Table (Table 6-4), determine takeoff
C.G. position. Enter this figure in space pro-
vided opposite TAKEOFF C.G. in inches.
Insure that this position is within the FWD
and AFT C.G. limit in LIMITATIONS
table.
15. Ref 14. Less expendables.
Fuel.
a.
Enter estimated weight of fuel to be
expended. Subtract this figure from
weight of fuel on board (reference 7).
This figure represents the landing fuel
weight. Use the Fuel Moments Table
(Table 6-2) to determine landing fuel
moment.
Subtract the landing fuel
moment from the total fuel moment on
board (reference 7). This figure repre-
sents the moment of fuel expended.
Enter in reference 14.
NOTE
Do not consider reserve fuel as expended
when determining ESTIMATED LAND-
ING CONDITIONS.
Flare/Chaff cartridges.
b.
Determine total weight of flares and/or
chaff cartridges
t h a t h a v e b e en
expended. Use the Aircraft Surviva-
bility Equipment table (Table 6-3) to
d e t e r m i n e l a n d i n g e x p e n d a b l es
moment. Enter figures in WEIGHT
and MOM/ 100 columns.
c.
Ref 15. Enter differences in weights
and MOM/100 figures between refer-
ence 12 and totals of reference 14.
Record figures in LIMITATIONS table as fol-
lows: In FORWARD and AFT space for PERMISSI-
BLE C.G. LANDING, enter a figure obtained as fol-
lows: Match weight figure recorded in reference 15
with a corresponding figure
in the GROSS
WEIGHT-POUNDS on Center-of-Gravity Limits
Table (Table 6-4). Determine the FORWARD limit
in inches figure for the weight matched and record
in the FORWARD space stated. Within the AFT
space for PERMISSIBLE C.G. LANDING, record
the AFT C.G. limit in inches. Check data against
PERMISSIBLE C.G. LANDING in LIMITATIONS
table.
d. Ref 16. Refer to Center-of-Gravity
Limits Table (Table 6-4) to determine
landing C.G. position. Enter this figure
in space provided opposite ESTI-
MATED LANDING C.G. in inches.
Check Ref 16 against PERMISSIBLE C.G.
LANDING in LIMITATIONS Table.
Necessary signatures must appear at bottom of
form.
