What is the normal configuration for switches and lights on the A320?

• A. Lights Out
• B. All On
• C. Dim/Off
• D. Partially On

Answer: (A)

The main idea is that in normal operation the cockpit is kept dark to avoid distraction and preserve night vision. On the A320, non-essential cockpit lighting is turned off, so the environment is referred to as lights out. The instrument and display backlighting remains available and is adjusted as needed, but the general state is minimal lighting to keep attention on flight instruments and outside environment. You’ll only bring lights up during specific phases like taxi, takeoff, or when visibility requires more illumination. This makes sense because excessive lighting can cause glare, waste power, and reduce the crew’s ability to read instruments quickly.
