Which action is a required pre-flight check for the Emergency Lighting System?

• A. Cover intact
• B. Charge battery for 60 minutes
• C. Verify oxygen flow
• D. Reset cabin crew checklist

Answer: (A)

The test focuses on ensuring the Emergency Lighting System is physically ready and protected so it will function when needed. Verifying that the cover is intact matters because the protective cover keeps the lighting unit free from dust, moisture, and damage, and it signals that the unit is in place and not tampered with. If the cover is missing or damaged, the system may fail to deploy properly during an outage, or hidden damage could be present requiring maintenance. The other actions described don’t pertain to the ELS: charging a battery for a set time isn’t a standard preflight check for the emergency lights, checking oxygen flow relates to the cabin oxygen system, and resetting the cabin crew checklist is a crew procedure rather than a component of ELS readiness.
