What does the takeoff safety speed (V2) depend on for the CRJ 200?

The takeoff safety speed (V2) for the CRJ 200 primarily depends on weight and configuration calculations. V2 is a critical speed that ensures the safety of the aircraft during the takeoff phase, particularly in the event of an engine failure after takeoff.

This speed is determined by several factors, mainly the aircraft's weight at the time of takeoff and the configuration settings (such as flap settings). Heavier aircraft require a higher V2 speed to maintain safe flight after an engine failure because they need more lift to overcome their weight. Additionally, different configurations, especially flap settings, affect the lift characteristics and stall speed of the aircraft. Therefore, these calculations must be performed prior to takeoff to ensure that V2 is appropriate for the specific flight conditions, ensuring that the aircraft can achieve safe climb performance.

While standard temperature, aircraft speed stability, and flight direction can influence overall aircraft performance and handling, they are not direct determinants of V2 in the same way that weight and configuration are.
