Most of us are aware of the dangers of carbon monoxide (CO) within our homes. CO is a by-product of burning hydrocarbon fuels, such as the 100LL AVGAS which is used by all the BBMF aircraft. The danger is that CO binds to the oxygen-carrying blood pigment, haemoglobin, more than 200 times more strongly than oxygen and therefore, reduces the ability of the circulatory system to carry life-critical oxygen around the body. The risk is also increased over time, as the half-life of CO is approximately five hours and it can take 24 hours or more to eliminate CO from the blood. The symptoms of CO poisoning, prior to incapacitation and death, include: headache, nausea, drowsiness and impaired cognitive functions, symptoms that would all have a marked effect on a pilot’s ability to fly safely.
