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
Giải thích
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.
