What is the definition of Lift in aviation terms?

In aviation, lift is defined as the upward force that enables an aircraft to rise off the ground and stay in the air. This force is generated primarily by the wings of the aircraft as it moves through the air. The shape of the wings and their angle relative to the airflow play a crucial role in producing lift, as they create a difference in air pressure above and below the wings. When the lift force exceeds the weight of the aircraft, the plane ascends. Understanding lift is fundamental for flight safety and operation, as it directly affects how pilots manage an aircraft during takeoff, cruising, and landing. While other forces, such as thrust (forward force) and drag (resisting force), are also important in the context of flight, lift specifically focuses on the upward movement which is critical for flight.
