In the event of smoke in the cabin, what is a typical response of the Cabin Atmosphere Control System?

When smoke is detected in the cabin, engaging smoke evacuation procedures is a critical response of the Cabin Atmosphere Control System. These procedures are designed to ensure passenger safety by effectively removing smoke from the cabin environment. This typically involves activating smoke detection and suppression systems, as well as possibly using ventilation to clear the air.

In an emergency situation involving smoke, the primary concern is the health and safety of all individuals aboard. Deploying smoke evacuation procedures can involve many tactical responses, including possibly altering airflow systems to enhance cabin ventilation and filtering out contaminants.

The other options may not directly address the presence of smoke or could potentially worsen the situation. For example, turning off all cabin lights could hinder visibility, making evacuation and emergency procedures more challenging. Increasing cabin pressure is typically not a method used to manage smoke, as it could trap more smoke inside rather than help clear it. Rerouting power to other systems may not have an immediate impact on the smoke situation and could detract from essential systems that need to operate effectively during an emergency. Thus, engaging smoke evacuation procedures stands out as the most appropriate and effective response in such a scenario.
