What is the speed defined as V2?

The correct answer is the speed at which the aircraft climbs with one engine inoperative. V2 is a critical airspeed during takeoff, particularly in multi-engine aircraft. It represents the minimum safe speed that an aircraft must reach to be able to climb in the event of an engine failure shortly after takeoff. At this speed, the aircraft can maintain a safe flight path and has sufficient thrust to ensure controllability, allowing pilots to perform necessary maneuvers or return to the airport if needed. This speed is particularly crucial for flight safety and performance calculations during takeoff.

Understanding the significance of V2 helps pilots and aviation professionals anticipate behavior in the event of engine loss, ensuring that operational procedures prioritize safety and efficiency during critical phases of flight.
