What does the term "V2" signify during aircraft takeoff?

The term "V2" refers to the takeoff safety speed that ensures a safe climb gradient in the event of an engine failure during the takeoff phase. This speed is crucial because it is the minimum required speed that an aircraft must reach to safely continue its climb after an engine failure occurs. Achieving V2 provides a buffer for the aircraft as it ascends, allowing pilots to maintain control and lift even with one engine inoperative.

While other speeds such as V1 (the decision speed) and V3 (the landing speed with reduced flaps) are also important in aviation, V2 specifically focuses on scenarios where the aircraft might face a critical situation during the takeoff phase. Understanding the significance of V2 helps ensure pilots are prepared for emergencies, highlighting its role in aviation safety during takeoffs.
