Sample Weight & Balance Problem
Complete the following sample weight and balance problem.
Conditions
Basic Empty Weight ................................................................................ 1590.0 lbs.
(Remember to use actual aircraft BEW for ight check.)
Front Pilots ........................................................................................................350 lbs.
Rear Passengers ................................................................................................. 50 lbs.
Baggage ............................................................................................ 2 Bags @ 75 lbs.
(May need to relocate some baggage to rear passenger seats.)
Max Ramp Weight ......................................................................................2,558 lbs.
Max Takeo/Landing Weight .................................................................2,550 lbs.
Max Baggage Weight ....................................................................................200 lbs.
Max Usable Fuel ................................................................................................48 gal.
Fuel Burn ..............................................................................................................20 gal.
Weight × Arm = Moment

Zero Fuel Weight = CG
CG = Moment / Weight
=
Usable Fuel
+
95.00

Ramp Weight =
Taxi Fuel (2.65 Gal.)
– 8
95.00
– 760
Takeo Weight = CG
CG = Moment / Weight
=
Fuel Burn
–
Landing Weight = CG
CG = Moment / Weight
Calculate the Following
1. Zero Fuel Weight
2. Zero Fuel CG
3. Takeo Weight
4. Takeo CG
5. From comparing the Takeo CG and Zero Fuel CG, which direction does
the CG move as fuel is burned o?
