Which items are safety-critical to verify during preflight of the Longitude 700's cabin and galley?

• A. Cabin pressurization checks, oxygen readiness, crew life vests, emergency equipment status, smoke detectors.
• B. Oxygen readiness only.
• C. Crew life vests and emergency equipment status only.
• D. Smoke detectors only.

Answer: (A)

The safety checks in the cabin and galley preflight focus on everything that keeps the occupants safe in an abnormal situation and ensures the crew can respond promptly. Verifying cabin pressurization confirms the environmental system is maintaining the correct cabin pressure and that indicators and controls show proper operation, which is essential for passenger comfort and safety at altitude. Oxygen readiness ensures there is a functioning oxygen system with adequate supply for both crew and passengers in case of depressurization or other hypoxia risk. Crew life vests must be available and accessible, particularly for overwater operations, so the crew can quickly deploy flotation gear if needed. Emergency equipment status means all required safety gear—fire extinguishers, first aid kits, life rafts or other survival gear, and related components—are aboard, serviceable, stowed correctly, and reachable. Smoke detectors must be functioning to provide early warning of any fire in the cabin or galley so the crew can act immediately. Taken together, these items cover the key safety channels: environmental integrity, breathable air, personal safety equipment, emergency readiness, and fire detection. Options that omit any one of these elements leave a safety gap.
