What is the minimum airspeed required for a go-around in the ERJ 170/175?

For the ERJ 170/175, the minimum airspeed required for a go-around is determined based on safe operational practices during the maneuver. The correct choice of 130 KIAS aligns with the aircraft's performance characteristics, ensuring that the aircraft is within its controllable airspeed envelope during the critical phases of flight.

This airspeed provides a sufficient margin above stall speed and allows for adequate control authority during the go-around process. This includes not only the handling of the aircraft while transitioning from descent to climb but also ensuring that there is sufficient thrust available to achieve a positive rate of climb. Operating below this threshold could lead to challenges in maintaining control through the transition, especially with adjustments in thrust and configuration changes that are typical during a go-around.

Maintaining a minimum airspeed of 130 KIAS helps pilots ensure that they meet the aircraft's performance requirements and responds effectively to the various factors that can affect stability and control during the maneuver. This speed is established in the aircraft's operational performance data and is an essential part of safe flying practices in the ERJ 170/175.
