What preflight checks are essential for safety devices on the 787?

• A. Ensure emergency equipment, oxygen, lighting, and evacuation slides are ready and not expired.
• B. Verify seat configurations and meal service readiness.
• C. Check baggage loading plan.
• D. Inspect the in-flight entertainment system.

Answer: (A)

The main idea here is that preflight checks focus on safety-critical systems and equipment that must function in an emergency. The best answer concentrates on making sure safety devices are ready and within their service life: emergency equipment is present and not expired, the oxygen system is ready to supply air to passengers and crew, cabin emergency lighting and exit signs will operate to guide people, and evacuation slides are properly armed, undamaged, and ready for rapid deployment. Why this fits: these elements directly affect passengers’ ability to survive and exit the aircraft quickly if something goes wrong. Emergency equipment must be accessible and within its expiration dates so it can be relied upon. Oxygen systems need to be charged and capable of delivering breathable air. The cabin’s escape route lighting ensures visibility even in smoke or darkness, and evacuation slides must function correctly to allow a swift egress. Together, they form the safety backbone of the preflight check. Checks like seat configurations, meal service readiness, baggage loading plans, or in-flight entertainment pertain to service and operations rather than the safety devices themselves, so they’re not the focus when evaluating essential preflight safety readiness.
