Which term describes maintaining cabin pressure as close to sea level as possible?

• A. Non-stop Flight
• B. Pressurization
• C. Layover
• D. Domicile

Answer: (B)

Pressurization is the system and process that keeps the cabin environment at a pressure close to sea level. It controls the cabin altitude so passengers and crew have enough oxygen and feel comfortable, even though the airplane is cruising hundreds of miles above the ground. In practice, the cabin is held at a low enough altitude—often about 6,000 to 8,000 feet—to minimize fatigue and hypoxia risks, while the aircraft itself operates at much higher outside altitudes. The other terms refer to flight schedule or crew bases and don’t describe how cabin pressure is managed.
