Where in an aircraft would you find carbon monoxide detectors?

Carbon monoxide detectors are found in aircraft cabins and cockpits to ensure the safety of the crew and passengers. Carbon monoxide is a colorless, odorless gas that can arise from incomplete combustion of fuels, particularly in engine operation. The presence of this gas poses a serious health risk, as it can lead to carbon monoxide poisoning.

By installing detectors in both the cockpit and cabin areas, aircraft are equipped to monitor and alert occupants to elevated levels of carbon monoxide, allowing for timely action to mitigate exposure and ensure safety during flight operations.

The other areas listed, such as the cargo areas, engine compartments, or only the cockpit, do not provide comprehensive coverage for carbon monoxide detection, which is critical in the areas where humans are present. Therefore, including detectors in both the cabin and cockpit guarantees that any potential hazard from carbon monoxide is effectively managed.
