Where are carbon monoxide detectors typically installed in an aircraft?

Carbon monoxide detectors are typically installed in the cockpit or cabin of an aircraft to ensure the safety of the crew and passengers. This is crucial because carbon monoxide is a colorless, odorless gas that can be produced during aircraft operation, particularly from exhaust fumes. By placing detectors in these areas, the crew can monitor for elevated levels of carbon monoxide and take necessary action if it is detected.

Having the detectors in the cockpit or cabin allows pilots and passengers to receive immediate alerts, which is essential for maintaining a safe environment while flying at altitude. In contrast, other areas like the cargo hold, engine compartment, or baggage area are less accessible and do not directly provide the immediate information needed for the occupants to respond to potential carbon monoxide exposure. The placement in operational areas where people are present is vital for proactive safety measures.
