How many airbrake panels deploy in AB2 mode?

In AB2 mode, all three airbrake panels per wing deploy, resulting in a total of six panels being activated. This configuration is designed to provide significant aerodynamic drag, which aids in deceleration and improved control during landing approaches or when descending. The comprehensive deployment ensures that the aircraft can effectively slow down, enhancing the pilot's ability to manage speed and descent rate during various phases of flight. The use of multiple panels increases the surface area that effectively contributes to drag, making it especially useful in situations requiring rapid speed reduction.

This mode is specifically engineered to optimize braking effectiveness without compromising the aircraft's stability and handling characteristics, which are critical during high-performance operational scenarios. Understanding the deployment mechanism is essential for pilots and maintenance crews, as it directly influences operational efficiency and safety during flight maneuvers.
