V/5IGIIT AND BALANCE
BY P.H,Ponish
To find the C G Aft Extreme, the air
plane must be loaded in such a manner
that all items will exert the extreme
aft moment. Let us continue with tho ex
ample given on Pago 2 of last vrook’s
P. A. Nov;s. Tho first lino v;ill bo the
sardo as before: Yv’'t(lbs) Arm.(in) Moment
AEW 650 16 10400
The specifications require a J3 C-65 Cub
to bo floTO solo from the roar scat onlvc
Tho roar seat is on an am of / 36 and
tho front seat on an arm of / 9, It is
obvious that tho most roarv/ard moment

Tho fuel tank is locatod on an arm of

tho greater vdll be the total aft monontf
Vfo use, theroforo; tho minimum fuol in

Maximum Except ToJio-off HP by 12, Tho
Maximum Except Take-off HP of the plane
in question is found in tho Operation

50 HP, 50 divided by 12 equals 4 l/6 gals
of fuol, Tho third 1 ino v/o put down is:
Fuol(min) 4 l/6 gals 25 lbs -18 -450
Oil must bo includod in all calculations
as explained last vraok,
Tho fourth line v/ill bo:
