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

The appropriate response of the Cabin Atmosphere Control System when there is smoke in the cabin is to engage smoke evacuation procedures. This process is critical in ensuring the safety of passengers and crew by quickly mitigating the presence of smoke and improving visibility.

Engaging smoke evacuation procedures typically involves activating the smoke removal systems, which may include increasing airflow or activating fans to direct smoke out of the cabin. This response also plays a vital role in enhancing the cabin's overall air quality by ventilating and diluting the smoke.

Other responses, while important in different contexts, do not directly address the immediate concern of smoke presence. For example, turning off all cabin lights may create additional danger by reducing visibility, while increasing cabin pressure would not effectively deal with the smoke and could potentially worsen the situation by preventing its evacuation. Rerouting power to other systems does not address the immediate need to ensure the safety and health of those on board during such an emergency.
