What is typically tested during operational carbon monoxide detection tests?

Operational carbon monoxide detection tests primarily focus on assessing the safety of heating and exhaust systems within an aircraft. This is crucial because carbon monoxide is a colorless, odorless gas that can pose serious health risks to passengers and crew if not properly managed. During these tests, the integrity of the combustion systems is evaluated to ensure that they are functioning correctly and not allowing carbon monoxide to infiltrate the cabin atmosphere.

By conducting these tests, aviation safety protocols are reinforced, thereby minimizing the risk of exposure to harmful gases that could lead to adverse effects on health during a flight. The other aspects mentioned, such as fuel efficiency, cabin pressure systems, and oxygen supply reliability, are not directly linked to carbon monoxide detection, thus making them irrelevant in this specific context.
