Zero Fuel Weight =
Usable Fuel
Ramp Weight =
Taxi Fuel (2.65 Gal.)
Takeoff Weight =
Landing Weight =
Calculate the Following
1. Zero Fuel Weight
2. Zero Fuel CG
3. Takeoff Weight
4. Takeoff CG
5. From comparing the Takeoff CG and Zero Fuel CG, which direction does
the CG move as fuel is burned off?
(Remember to use actual aircraft BEW for flight check.)
