Thrust Required For Climbing Flight Calculator

The Thrust Required for Climbing Flight (T_req​) is the amount of engine thrust that an aircraft needs to generate in order to overcome aerodynamic drag and support its weight while ascending in a climb. In climbing flight, the aircraft is moving upward, and to maintain a climb, the thrust produced by the engines must be greater than the total aerodynamic drag and the component of the aircraft’s weight acting along the climb path. The formula for thrust required in climbing flight is often expressed as:

Where:

• T_req​ is the thrust required for climbing flight,
• $D$ is the aerodynamic drag,
• $W$ is the weight of the aircraft, and
• $\gamma$ is the climb angle.
