How many flight phases does the Flight Warning System categorize?

The Flight Warning System of the A320 categorizes flight phases into ten distinct stages. This classification is crucial for the aircraft's systems to provide timely and relevant warnings to the flight crew during various stages of flight. Each phase is defined by specific parameters and operational considerations that align with the aircraft's performance and safety protocols. Recognizing the ten phases allows pilots to understand the context of alerts they receive and helps them manage the aircraft effectively throughout its flight.

In contrast, the other options reflect incorrect counts of phases, likely leading to misunderstandings regarding the complexity and capabilities of the Flight Warning System. The design of the system focuses on ensuring pilots have the necessary information to respond appropriately in each phase, emphasizing the importance of a clear and structured categorization.
