Which term describes the luminous markings used to identify emergency exits?

• A. Photo-luminescent Emergency Markings
• B. Morse Emergency Markings
• C. Photo-Printed Exit Signs
• D. Pilot Emergency Mode

Answer: (A)

Photoluminescent emergency markings are glow-in-the-dark indicators that mark emergency exits. They absorb light when it’s available and then emit a visible glow in darkness, helping people find doors, escape routes, and floor paths if cabin lights fail or visibility is reduced by smoke. This passive illumination doesn’t rely on electrical power, which is crucial in an emergency when lighting may be compromised. The other options don’t fit because Morse emergency markings would imply signaling via Morse code rather than visual exit cues; photo-printed exit signs describe signs that are printed and illuminated by external light rather than glow-in-the-dark material; and pilot emergency mode isn't a recognized term for exit markings.
