What typically limits minimum V2 speed (V2min) in various flight conditions?

The correct answer is based on the concept of minimum control speed, which is critical for safe takeoffs and landings. Minimum V2 speed (V2min), or the takeoff safety speed, is primarily influenced by stall speed and minimum control speed.

When considering a failure of an engine during takeoff, the aircraft must maintain a speed above the minimum control speed to ensure that it can be controlled effectively and has enough authority over the ailerons and rudder for coordinated flight. The stall speed indicates the lowest speed at which the aircraft can maintain controlled flight. Consequently, V2min must be set above both the stall speed and the minimum control speed to ensure safety in various flight conditions, particularly in the event of an engine failure.

In this context, if V2min were set too low, there would be a risk of stalling or losing control, especially during critical flight phases following engine failure. Thus, the relationship between stall speed and minimum control speed establishes the parameters for determining V2min, highlighting the importance of maintaining adequate performance and control margins during takeoff.
