Aircraft Vehicle

The cockpit of an aircraft contains flight instruments on an instrument panel, and the controls which enable the pilot to fly the aircraft. In most airliners, a door separates the cockpit from the passenger compartment. After the September 11, 2001 terrorist attacks, all major airlines fortified the cockpit against access by hijackers.
On an airliner, the cockpit is usually referred to as the flight deck. This term derives from its use by the RAF for the separate, upper platform where the pilot and co-pilot sat in large flying boats.
• Cabin
An aircraft cabin is the section of an aircraft in which any passengers travel, often just called the cabin. At cruising altitudes, if the surrounding atmosphere is too thin to breathe without an oxygen mask, cabin pressurization adapts the cabin to atmospheric pressures.
