What is a common symptom of carbon monoxide poisoning that pilots should be aware of?

1. Euphoria

2. Intense hunger

3. Blurred vision

4. Increased reflexes

The correct answer is: Blurred vision

One of the common symptoms of carbon monoxide poisoning is indeed blurred vision. This condition arises because carbon monoxide interferes with the blood's ability to transport oxygen, which is crucial for maintaining normal physiological functions. As a result, the brain and other vital organs can become oxygen-deprived, leading to various symptoms, including visual disturbances. Pilots must be particularly vigilant as they operate in environments where carbon monoxide can accumulate, such as aircraft with internal combustion engines that might have exhaust leaks. Recognizing blurred vision as a symptom is critical for maintaining situational awareness and safety while flying. Awareness of this symptom can lead to prompt action to mitigate exposure and ensure the pilot's capability to operate the aircraft safely.
