What is the primary function of crew monitoring during flight?

The primary function of crew monitoring during flight is to ensure safety, particularly during approach and landing. This phase of flight is often the most critical and demanding due to changing flight dynamics, the complex tasks involved, and the need for precise execution of procedures. Crew monitoring involves actively observing each other's actions, confirming that required checklists are completed, and ensuring that the aircraft's systems are functioning correctly. This collaborative attention helps prevent errors and enhances safety, as it focuses on maintaining situational awareness and adherence to standard operating procedures during this high-stakes phase of flight.

While maintaining communication with air traffic control, assisting in navigation, and managing cabin crew duties are important aspects of aviation operations, they do not specifically align with the primary goal of crew monitoring, which is centered on enhancing safety through teamwork and vigilance, particularly during critical phases like approach and landing.
