What is the role of lift in climb calculations?

The role of lift in climb calculations is crucial because for an aircraft to achieve a successful climb, the lift generated by the wings must exceed the total weight of the aircraft. When the lift is greater than the weight, the aircraft can ascend; this is due to the net upward force created when lift surpasses the gravitational pull acting on the aircraft.

This principle is rooted in the basic laws of physics, where an object will only move in the direction of the greater force applied to it. During a climb, pilots must calculate the required lift not only to overcome their aircraft’s weight but also to account for any additional factors such as increased drag, changes in thrust, and power settings that can affect climb performance.

Understanding this concept allows pilots to effectively plan for climbs at various weights, altitudes, and configurations, ensuring safe and efficient ascent to cruising altitude.
