Certified Flight Instructor - Flight Instructor Airplane Practice Exam

What is the primary reason for performing a weight and balance calculation before flight?

1. To ensure fuel efficiency.

2. To determine passenger comfort.

3. To ensure safe operation of aircraft.

4. To adhere to airline regulations.

The correct answer is: To ensure safe operation of aircraft.

Performing a weight and balance calculation before flight is crucial primarily to ensure the safe operation of the aircraft. Each aircraft has specified weight limits, both in total and in terms of its center of gravity (CG). Exceeding these limits can lead to significant control and performance issues, ultimately compromising safety during flight. Proper weight distribution is vital to maintain balance and stability, as an improperly loaded aircraft can affect its handling characteristics, leading to difficulties in takeoff, flight, and landing phases. Weight and balance calculations help pilots ensure that the aircraft remains within the allowable limits for safe flight operations. This is linked to performance factors such as takeoff distance, climb rate, and landing requirements. By confirming that the aircraft is loaded correctly, pilots can enhance their mission's safety and avoid potential incidents caused by improper loading.
