What is the maximum crosswind component for takeoff?

The maximum crosswind component for takeoff on the ERJ 170/175 is specified as 35 knots. This limitation is critical for ensuring safe aircraft performance during takeoff operations. Exceeding this crosswind limit can significantly affect the controllability of the aircraft, particularly during the takeoff roll and initial climb phase when the aircraft is still closely aligned with the runway.

The specified limit takes into account the aircraft's design characteristics, such as its wing configuration and control surface effectiveness, which can vary in response to wind conditions. This limitation helps pilots maintain optimal control and minimize the risk of losing directional stability due to strong crosswinds.

Understanding this limitation is key for pilots as it ensures that they make informed decisions regarding takeoff in varying weather conditions, thereby enhancing safety and operational efficacy during flight operations.
