Carbon Monoxide (CO) is an extremely hazardous colourless, odourless, and tasteless gas that can lead to potentially fatal pilot incapacitation in small quantities. Deadly Carbon Monoxide (CO) is produced wherever fossil fuels (such as gasoline, kerosene, diesel, natural gas, and propane) are combusted without sufficient oxygen.
Powered aircraft are only sometimes fitted with a CO detector, but more often than not they lack a replacement date. This is extremely dangerous as most commercially available CO detectors lose their protective function after a period of about 90 days!
