What is an effect of poor weight and balance?

The correct answer highlights the significant risks associated with poor weight and balance in an aircraft. When the aircraft's weight distribution is not optimized, it can lead to a number of handling issues. For instance, an aircraft that is too heavy or unevenly balanced may experience difficulties in controlling its pitch, roll, or yaw during flight, which can make maneuvers more difficult and less predictable. This can also negatively affect the aircraft's stall characteristics, making it more likely to enter a stall at higher airspeeds or in a banked turn.

Safety risks are critical in this context, as poor handling can contribute to accidents or incidents such as loss of control during takeoff or landing. It can also lead to increased wear and strain on various components of the aircraft, potentially compromising structural integrity over time.

Good weight and balance practices are vital for ensuring smooth flight operations, optimal performance, and overall safety. Thus, this choice emphasizes the importance of adhering to weight and balance standards in aviation.
