When the landing gear is extended, pitch alternate law will degrade to pitch direct law if the autopilot is not engaged. This is an important aspect of the flight control laws on the A320. In alternate law, the aircraft's flight control systems have reduced capability but still provide some level of protection against an uncontrollable pitch situation. However, extending the landing gear while the autopilot is off signals a transition to a less stable regime of flight control.

When the autopilot is disengaged and the landing gear is deployed, the system prioritizes direct control by the pilot over the more complex handling of the flight control laws governed by alternate law. In contrast, if the autopilot remains engaged while the landing gear is extended, the pitch control systems continue to operate under alternate law until further actions or triggers occur, maintaining the limits and protections provided by that law.

Understanding how these laws interact with autopilot engagement and landing gear deployment is crucial for pilots as it impacts aircraft handling characteristics during critical phases of flight, such as approach and landing.
