Aviation Review: Weight, Balance, and Stalls

The datum is always located

• At the pilots seat

• At the center of gravity

• At the center of lift

• Wherever the manufactured decided it would be

The main reason weight changes during an airplane's flight is

• The burning of fuel

• The movement of passrengers

• The ingress of air from the outside

• The pressurization and depressurization of the airplane cabin

Heading towards the nose the arm length is

• Positive

• Negative

Heading towards the tail the arm length is

• Positive

• Negative

In order for it to be safe to fly an aircraft the center of gravity

• Must be exactly on the Datum

• Must be even with the Center of Ligt

• Must fall in the acceptable range from the Datum

• Must be located on the center of the wings.

One consequence of the Center of gravity being too far aft is

• The plane won't fly as fast

• The plane might not be able to recover from a stall

• The plane will tend to pitch nose down

• The plane will tend to roll to the right
