Weight and Balance

Question 1

What are the effects of a forward Center of Gravity?

Answer 1

C.G. that is relatively forward (but not out of range) affects the aircraft in the following ways.

• More longitudinally stable
• Less controllable
• Higher stall speed
• Slower cruise speed
• Longer takeoff roll
• More difficult to flare

Question 2

What does it mean when an airplane is more longitudinally stable?

Answer 2

• Involves pitching motion about the lateral axis.
• Longitudinally stable means aircraft will naturally return to same attitude after being disturbed.

Question 3

What are the effects of a aft center of gravity?

Question 4

Weight Shift Formula

If you move something backwards it ________ the total moment

Answer 4

If you move something backwards it increases the total moment, so you would add the difference in lbs/inches

Question 5

Weight Shift Formula

If you move something forward in the airplane it ________ the total moment

Answer 5

If you move something forwards it decreases the total moment, so you would subtract the difference in lbs/inches
