Question 3

Upon landing, the front passenger (180 pounds) departs the airplane. A rear passenger (204 pounds) moves to the front passenger position. What effect does this have on the CG if the airplane weighed 2,690 pounds and the MOM\/100 was 2,260 just prior to the passenger transfer?

Accepted Answer

The CG moves forward approximately 3 inches.

Answer

The weight changes, but the CG is not affected.

Answer

The CG moves forward approximately 0.1 inch.

Question 4

Answer

Drain 12 gallons of fuel.

Answer

Transfer 12 gallons of fuel from the main tanks to the auxiliary tanks.

Question 5

(Refer to Figures 32 and 33.) What effect does a 35-gallon fuel burn (main tanks) have on the weight and balance if the airplane weighed 2,890 pounds and the MOM\/100 was 2,452 at takeoff?

Accepted Answer

Weight is reduced by 210 pounds and the CG is aft of limits.

Answer

Weight is reduced by 210 pounds and the CG is unaffected.

Answer

Weight is reduced to 2,680 pounds and the CG moves forward.

Question 6
