PPL PPL Weight and Balance 3

Question 1

An aircraft has a total weight of 2,400 pounds and a total moment of 192,000 pound-inches. What is the CG location from the datum?

Accepted Answer

80 inches

Answer

70 inches

Answer

75 inches

Answer

85 inches

Question 2

When an aircraft is loaded to its maximum certificated gross weight compared to a lighter load, what typically occurs?

Accepted Answer

Stall speed increases and climb rate decreases

Answer

Stall speed decreases and climb rate improves

Answer

Cruise speed increases significantly due to reduced parasite drag

Answer

Fuel consumption decreases because the engines work less hard

Question 3

As fuel is burned during a flight, how does CG location change?

Accepted Answer

CG shifts in a direction that depends on the fuel tank location relative to the aircraft CG

Answer

CG remains constant because weight decreases proportionally at all stations

Answer

CG always shifts forward as the aircraft becomes lighter

Answer

CG always shifts aft as fuel is burned from wing tanks

Question 4

In weight and balance terminology, 'arm' refers to what measurement?

Accepted Answer

The horizontal distance from the datum to the item or station

Answer

The total weight of all items loaded in the aircraft

Answer

The moment contributed by a specific item or station

Answer

The maximum load capacity of a specific baggage compartment

Question 5

If you load 50 pounds of baggage at a station located 120 inches aft of the datum, what moment does this item contribute?

Accepted Answer

6,000 pound-inches

Answer

2.4 pound-inches

Answer

170 pound-inches

Answer

12,000 pound-inches

Question 6

Which loading condition is generally considered the MOST dangerous for flight safety?

Accepted Answer

CG positioned aft of the approved aft limit

Answer

Loaded within limits but near maximum gross weight

Answer

CG within limits but near the forward edge of the envelope

Answer

Aircraft slightly under maximum gross weight with a forward CG

Question 7

Which of the following best describes the 'zero fuel weight' limitation used on some aircraft?

Accepted Answer

The maximum allowable weight of the aircraft excluding usable fuel

Answer

The weight of the aircraft before any fuel is added during preflight

Answer

The weight of the aircraft with only IFR reserve fuel remaining in the tanks

Answer

The empty weight of the aircraft minus the weight of the fuel system components
