What is the definition of V2?

The definition of V2 is indeed the speed at which the aircraft can climb with one engine inoperative. This speed is critical for multi-engine aircraft, especially during takeoff, as it represents the minimum safe speed for continued climb if one engine fails. Achieving V2 ensures that the aircraft has sufficient aerodynamic performance to maintain a positive rate of ascent, allowing the pilot to safely navigate away from the runway in the event of an engine failure.

This speed is determined through careful calculations that take into account the weight of the aircraft, the configuration for takeoff, and the specific characteristics of the aircraft type. It plays a vital role in ensuring safety margins during the critical phases of flight immediately after takeoff.

In contrast, the minimum safe landing speed and the speed for initiating landings do not relate to engine failure scenarios and thus do not define V2. Similarly, while there is a takeoff safety speed with two engines, V2 specifically pertains to the scenario of engine inoperative operations, making the provided answer the correct definition.
