Why are cabin lights dimmed for take-off and landing on night flights?

• A. To prevent blinding effect in the event of an emergency in darkness
• B. To save power
• C. To create mood lighting
• D. To reduce heat

Answer: (A)

Preserving night vision for safe evacuation. Dimming the cabin lights during take-off and landing on night flights keeps passengers’ eyes adapted to low light, so if an emergency occurs in darkness they can see exits, floor path lighting, and signs clearly and quickly. Bright cabin lighting could cause glare or temporary blindness as people re-adapt to darkness, slowing or hindering an orderly evacuation. The dimmed lighting helps ensure a faster, safer response while still allowing crew to perform their duties and passengers to move safely. It’s not about saving power, mood lighting, or reducing heat.
