Photo-luminescent escape path lights must be charged with cabin lights on bright for 15 minutes.

• A. True
• B. False
• C. Only during preflight
• D. Not specified

Answer: (A)

Photoluminescent escape path lighting relies on energy stored from ambient light to glow when power is out, so it must be charged beforehand. Exposing these lights to bright cabin lighting for about 15 minutes before departure ensures they reach a sufficient brightness to guide passengers during an evacuation in darkness. If they aren’t properly charged, the glow may be too dim to be useful. That’s why this statement is true: the system needs that 15-minute charge with cabin lights on bright prior to flight.
