Which flight control law is indicated in the alternate law?

In the context of flight control laws for the A320, alternative law refers to a specific mode of operation that is engaged when the aircraft's primary flight control system experiences a failure or when certain limitations are exceeded in normal law. This mode provides reduced protection compared to normal law but still maintains some level of control and protection.

Under alternate law, the flight control computer modifies pilot inputs differently than in normal law, allowing the aircraft to remain flyable while prioritizing safety. This mode is essential for managing the aircraft effectively in situations where full flight protection might not be available, ensuring the pilots can still control the aircraft without reverting to fully manual maneuvers.

Overall, understanding alternate law is critical for pilots to navigate scenarios where the aircraft's flight control systems may not function optimally, allowing them to respond appropriately and ensure safe operation of the aircraft.
