What is the maximum deflection of both sidesticks when moved simultaneously?

The maximum deflection of both sidesticks when moved simultaneously is equivalent to the maximum deflection of a single stick. This is because the control system is designed to prioritize the input from either of the sidesticks, effectively making the maximum combined movement equal to that of one stick operating at its full capacity. If both sidesticks are deflected to their maximum, the aircraft's flight control system will respond as if only the maximum deflection of one stick is in play.

This design is crucial for maintaining controlled and predictable flight behavior, especially in situations where two pilots might have simultaneous inputs. It prevents over-controlling the aircraft and ensures a harmonious response from its systems, which is vital for safety and efficiency in flight operations.
