What effect does weight have on an aircraft’s performance?

• A. Increased weight leads to lower stall speed
• B. Increased weight allows for faster climb rates
• C. Increased weight leads to higher stall speed and longer takeoff/landing distances
• D. Increased weight decreases fuel consumption

Answer: (C)

Increased weight has a significant impact on an aircraft's performance, and one of the primary effects is that it leads to higher stall speeds and longer takeoff and landing distances. When the weight of an aircraft increases, the wings must generate more lift to maintain level flight, which requires a higher airspeed. This results in an increased stall speed because the aircraft must reach a higher speed to keep the wings producing enough lift to avoid stalling. Additionally, greater weight necessitates a longer distance to achieve the required takeoff speed during takeoff, as more lift is needed to lift the heavier aircraft off the ground. Similarly, during landing, a heavier airplane will require a longer distance to descend and safely come to a stop due to the increased momentum associated with the added weight. Understanding these principles is crucial for pilots, as they must account for weight in their flight planning and operations to ensure safety and effectiveness.
