Operations & SafetyQuestion 94 of 100
During a long summer survey in direct sun, the visual observer reports a headache, dizziness, and muscle cramps. What is the most likely cause and the best immediate response?
a.Night vision loss; wait about 30 minutes for the eyes to adapt
b.Carbon monoxide exposure; move the control station upwind
c.Dehydration and heat stress; rest in shade and drink fluids
d.Normal eye strain; issue polarized sunglasses and keep flying
Explanation
Headache, fatigue, dizziness, and cramps during hot outdoor work are classic signs of dehydration and heat stress, and the response is to stop, get out of the sun, and rehydrate. Dark adaptation applies to night vision, not to symptoms in bright sun. Carbon monoxide is a cabin hazard for manned aircraft, and treating the symptoms as ordinary eye strain ignores a condition that degrades the crew's judgment.
