What happens when lift and thrust are greater than weight and drag?

When lift and thrust exceed weight and drag, the airplane experiences a net upward force. Lift is the aerodynamic force that counteracts weight, allowing the aircraft to rise, while thrust propels it forward. When these two forces are greater than their counterparts, the aircraft is able to ascend into the air.

In aviation terms, this condition signifies that the aircraft is not only overcoming gravitational forces but also gaining altitude. The components of aerodynamics, including speed, angle of attack, and the design of the wings, work in harmony to enhance lift. This scenario is essential in various flight maneuvers, including takeoff and climb-out, which allow the aircraft to reach cruising altitude safely.

The options indicating descent, level flight, or spinning are scenarios that would occur under different conditions of force balance. In essence, the concept of lift and thrust overpowering weight and drag firmly establishes a positive vertical movement of the aircraft.
