Flight Flashcard - Weight

Front

What happens if an airplane is loaded with a center of gravity (CG) that is excessively too far forward?

Back

The plane may pitch nose down and have difficulty in takeoff.

Front

How does loading an airplane to the most aft CG affect its stability at different speeds?

Back

It makes the plane less stable at all speeds.

Front

Why might you lose elevator authority to lift the nose for takeoff if the CG is too far forward or aft?

Back

Because the elevator cannot generate enough force.

Front

What is the formula to calculate the CG shift?

Back

CG shift = (178/2348) * d feet.

Front

If a passenger weighing 178 pounds moves from the front seat to the rear seat, how much does the CG change if the aircraft gross weight is 2348 pounds?

Back

The CG changes 1.0 inches aft.

Front

Define Center of Gravity (CG) in aviation.

Back

The point where the total weight of the aircraft is considered to be concentrated.

Front

What is the effect of a forward CG on an aircraft's takeoff performance?

Back

It can cause the aircraft to stall during takeoff due to insufficient lift.

Front

Explain the relationship between CG and aircraft stability.

Back

A forward CG increases stability, while an aft CG decreases stability.

Front

What is the significance of maintaining the CG within specified limits?

Back

It ensures safe flight characteristics and performance.

Front

How does CG affect fuel efficiency in an aircraft?

Back

A well-balanced CG can reduce drag and improve fuel efficiency.
