In the context of CACS, why is monitoring cabin air quality crucial during long flights?

Monitoring cabin air quality is essential during long flights primarily to prevent the spread of airborne viruses and promote passenger health. During extended periods in a confined space like an aircraft cabin, passengers are at risk of exposure to pathogens that can easily circulate in the air. Maintaining proper air quality helps to reduce the concentration of these airborne contaminants by utilizing effective ventilation systems, filtration methods, and maintaining appropriate humidity levels.

Ensuring that the cabin air meets health standards is vital for passenger comfort and safety, especially on long flights where passengers spend several hours in close proximity to one another. High levels of air quality contribute to a healthier cabin environment, thereby minimizing the likelihood of illness and enhancing the overall flying experience for everyone on board.
