Which task is part of preflight checks before boarding begins?

• A. Refill beverage carts
• B. Calibrate nav systems
• C. Inspect exits and safety equipment
• D. Update passenger manifest

Answer: (C)

Inspecting exits and safety equipment is tied directly to ensuring the cabin is ready for an emergency and that passengers can evacuate safely if needed. Before boarding starts, crews verify that all exits are accessible, unobstructed, and clearly marked, and that safety gear like life vests, fire extinguishers, and emergency devices are present, functional, and within serviceable limits. This step is a core part of making sure the aircraft can be evacuated quickly and safely if something goes wrong.

Refilling beverage carts is a service task aimed at preparing for passenger service. Calibrating nav systems is a pilot-focused check on flight systems, typically done in the cockpit. Updating the passenger manifest is administrative and logistical, not a safety readiness check.
