Takeoff speed is the minimum speed an aircraft must reach to become airborne. This speed varies based on several factors, including the aircraft's weight, wing design, and environmental conditions like wind and temperature. Pilots calculate this speed to ensure a safe and efficient takeoff. During takeoff, the aircraft accelerates down the runway until it reaches this critical speed. Once achieved, the pilot can pull back on the control yoke, allowing the wings to generate enough lift to rise into the air. Understanding takeoff speed is essential for safe flight operations in aviation.
