Question 1

Find the the Center of Gravity, if Weight is 1250 lb and Moment is 80,750 in-lb

Answer 1

64.6”

• 60”
• 55.7”

Question 2

Identify the formula to calculate how much ballast is needed to bring the center of gravity within the limits?

Answer 2

Loaded weight of aircraft x (Distance CG is out of limits) / Arm from ballast location to affected limit.

• Loaded weight of aircraft / Arm from ballast location to affected limit
• Loaded Weight of aircraft x Distance CG is out of limits

Question 3

Find the Center of Gravity and the Empty Weight?

Answer 3

Empty Weight - 1502.5 lb, Center of Gravity - 55.2”

• Empty Weight - 2000 lb, Center of Gravity - 55.2”
• Empty Weight - 1502.5 lb, Center of Gravity - 65”

Question 4

The width of the wing on an airplane is known as:

Answer 4

Chord

• Swept back Wing
• Tapered Wing

Question 5

If an aircraft CG is found to be at 24 percent of MAC, that 24 percent is an expression of the

Answer 5

distance from the LEMAC.

• distance from the TEMAC.
• average distance from the LEMAC to the wing center of lift.

Question 6

Maximum zero fuel weight is the

Answer 6

maximum permissible weight of a loaded aircraft (passengers, crew, and cargo) without fuel.

• basic operating weight without crew, fuel, and cargo.
• dry weight plus the weight of full crew, passengers, and cargo.

Question 7

If the empty weight CG of an airplane lies within the empty weight CG limits,

Answer 7

it is not necessary to calculate CG extremes.

• it is necessary to calculate CG extremes.
• minimum fuel should be used in both forward and rearward CG checks.

Question 8

Most modern aircraft are designed so that if all seats are occupied, full baggage weight is carried, and all fuel tanks are full, what will be the weight condition of the aircraft?

Answer 8

It will be in excess of maximum takeoff weight.

• It will be at maximum taxi or ramp weight.
• It will be at maximum basic operating weight (BOW).

Net weight at left main gear 9,770 pounds
Net weight at tail gear 1,970 pounds

Answer 9

60.31 inches.

• 62.92 inches.
• 58.54 inches.
