How can flight readiness be maintained in extreme temperatures?

• A. Increasing cabin humidity
• B. Attaching temperature-control devices to preserve body temperature
• C. Wearing appropriate clothing and conditioning
• D. Drinking only water

Answer: (C)

Keeping flight readiness in extreme temperatures comes down to how your body manages heat through clothing and conditioning. Wearing appropriate clothing provides insulation, moisture-wicking, and ventilation, with layered options that trap heat in the cold and allow heat to escape when it’s hot. This helps keep your core temperature stable, preserves dexterity, and maintains alertness and decision-making during demanding flight tasks. Pairing clothing strategy with conditioning—good cardiovascular fitness, acclimatization to heat or cold, and practice with thermal stress—improves blood flow, reduces fatigue, and supports steady performance in challenging conditions.

Increasing cabin humidity, while it can affect comfort, isn’t the primary way to maintain readiness in extreme temperatures. External temperature-control devices worn on the body aren’t standard practice and can hinder mobility or add risk. Drinking only water neglects overall hydration balance and doesn’t directly address how to regulate body temperature or sustain physical conditioning during temperature extremes.
