What is the term for the point where lift equals weight?

• A. Stall point
• B. Takeoff point
• C. Equilibrium point
• D. Climb point

Answer: (C)

The term for the point where lift equals weight is referred to as the equilibrium point. At this point, the forces acting on the aircraft are balanced, meaning that the aircraft is neither ascending nor descending. This is crucial for stable flight because when lift exactly equals weight, the aircraft maintains a constant altitude. Understanding this concept is essential for pilots, as it aids in determining the conditions necessary for level flight. In practical terms, if the lift increases beyond the weight, the aircraft would begin to climb, and if lift decreases below weight, the aircraft would descend. Therefore, recognizing the equilibrium point is fundamental for effective flight management and performance.
