AMT Aircraft Weight and Balance Questions and Answers

Question 1

An aircraft is loaded such that its center of gravity (CG) is located aft of the allowable range. Which of the following is a likely consequence of this condition?

Accepted Answer

Difficulty recovering from a stall.

Answer

Increased longitudinal stability.

Answer

Difficulty in raising the nose during takeoff.

Answer

Reduced cruise speed and fuel efficiency.

Question 2

Which of the following defines an aircraft's 'useful load'?

Accepted Answer

The difference between the maximum takeoff weight and the basic empty weight.

Answer

The weight of the crew, passengers, and cargo, but not fuel.

Answer

The total weight of the aircraft with all seats filled and maximum baggage.

Answer

The weight of the airframe, engines, and all permanently installed equipment.

Question 3

A technician must calculate the center of gravity of an aircraft. What is the correct formula to use?

Accepted Answer

Total Moment / Total Weight

Answer

Total Weight / Total Moment

Answer

Total Arm x Total Weight

Answer

(Total Weight + Total Moment) / 2

Question 4

During a pre-weighing inspection, a technician is preparing an aircraft according to the Type Certificate Data Sheet (TCDS) and maintenance manual. Which of the following is a critical step in this preparation?

Accepted Answer

Leveling the aircraft both longitudinally and laterally.

Answer

Ensuring the fuel tanks are filled to maximum capacity.

Answer

Positioning all flight controls in the neutral position.

Answer

Verifying the baggage compartment is completely empty.

Question 5

A modification adds a new antenna weighing 5 pounds at an arm of +150 inches. The aircraft's total weight before the modification was 2,500 pounds with a total moment of 212,500 inch-pounds. What is the new center of gravity?

Accepted Answer

85.05 inches

Answer

85.00 inches

Answer

85.30 inches

Answer

84.70 inches

Question 6

What is the primary effect of loading an aircraft with a center of gravity (CG) at the forward limit?

Accepted Answer

Increased stability and higher stall speed.

Answer

Decreased stall speed and improved fuel efficiency.

Answer

Reduced stability and lighter control forces.

Answer

Improved takeoff performance and shorter landing roll.
