Question ID: #1102
Sidestick Inputs and Surface Movement
When both sidesticks are moved simultaneously, either in the same direction or in opposite directions, the movement of the control surfaces is determined by the algebraic sum of the deflections of both sticks.
Key Principle:
- The surface movement is proportional to the combined input from both sticks.
- Inputs in the same direction add together, resulting in greater surface movement.
- Inputs in opposite directions partially cancel each other, reducing the net effect.
Operational Impact:
- Pilots can provide simultaneous inputs, and the system will calculate the resulting movement based on their combined actions.
- Coordination between pilots is essential to avoid conflicting inputs that could reduce control effectiveness.
Key Notes:
- The control surfaces respond to the algebraic sum of sidestick deflections.
- If conflicting inputs persist, the sidestick priority system can deactivate one stick.
