The ELACs control which specific primary flight controls?

The correct answer indicates that the ELACs (Elevator Feel and Control Computers) are responsible for controlling the ailerons and elevators on the A320 aircraft. This is significant because the ailerons are utilized for roll control, while the elevators manage pitch control, which are both critical for the aircraft's maneuverability and stability.

ELACs play a vital role in managing the flight control laws that affect how the aircraft responds to pilot inputs. They ensure that the ailerons move in coordination with the elevators, providing a smooth and controlled flight experience. By moderating the movement of these surfaces, ELACs help maintain the aircraft’s trim and stability during various phases of flight, including takeoff, cruising, and landing.

Understanding the roles of different flight control computers is crucial for pilot training, as this knowledge directly impacts how pilots interact with the aircraft's controls and respond to handling characteristics during flight operations. The answer highlights the essential functions ELACs perform in maintaining aircraft safety and performance.
