What is V2 speed during takeoff?

V2 speed during takeoff is referred to as the takeoff safety speed. This speed is crucial as it represents the minimum speed at which an aircraft can safely climb in the event of an engine failure during the takeoff phase. Achieving V2 ensures that the aircraft has adequate performance capabilities to maintain control and altitude, thereby enhancing safety during this critical stage of flight.

This speed is calculated based on factors like the aircraft's weight, runway length, environmental conditions, and specific aircraft performance characteristics. It is specifically designed to provide a safety margin, allowing for a robust climb rate in case of an emergency situation.

Understanding V2 is essential for pilots and dispatchers, as it represents a baseline for operational safety during takeoff, allowing for contingency plans should an emergency arise. It is also distinct from cruising speeds or ascent profiles, which are relevant at different phases of flight, further emphasizing its unique role during takeoff.
