During which flight phases is weight and balance distribution critical?

• A. During taxi and takeoff
• B. Takeoff and landing
• C. Cruise
• D. During boarding

Answer: (B)

Weight and balance affects how the aircraft behaves in flight, especially its stability and controllability. The phases where balance matters the most are takeoff and landing because the airplane is operating at or near performance limits and undergoing significant changes in speed, angle of attack, and pitch. During takeoff, the center of gravity determines how easily the airplane can rotate to the required nose-up attitude, how quickly liftoff occurs, and how the initial climb behaves. An inappropriate balance can make rotation sluggish or require more elevator authority than is available, increasing takeoff distance and potential handling issues. During landing, balance influences the pitch attitude through the approach, the flare, and the touchdown. CG position affects stall margins and how effectively you can manage the airplane's pitch during the critical ground contact phase. If the balance is off, you risk unstable approach, difficulty in achieving a smooth flare, or deranged landing performance. In cruise or boarding, the loads are more stable and changes are gradual, so balance remains important but the immediate safety and control concerns are not as acute as during takeoff and landing.
