Aircraft Cabin

The aircraft cabin is typically the largest section of the airplane as it is used to contain the passengers or cargo. The majority of the passengers enter the aircraft cabin from the front while the cargo are loaded in-between the front and the middle of the cabin and then evenly distributed to balance the weight. Most airlines provide premium paying passengers the benefit of early boarding, extra space for carry-ons and the ability to be the first to exit the cabin upon arrival. Commercial aircraft seating is typically very congested and packed in order to optimize the cabin space and accommodate the largest number of passengers possible while business and general aviation airplanes are more focused on comfort and service.

History

Aircraft cabin (pre-1938)

Early aviation cabin designs were typically open to allow the pilots to see landmarks like railroads, telegraph wires, lakes and rivers for navigation (Navigation Programs, 2015). Over time, aircraft manufactures developed an enclosed flight deck to allow greater comfort for the passengers and crew. Towards the end of the 1930s, updated aircraft design began to take shape similar to today’s modern aircraft with storage for cargo underneath the passenger seating areas in the main cabin.

Aircraft cabin (1938-Modern)

In 1938, Boeing released the Boeing 307 Stratoliner which was the first successful passenger airliner with a pressurized cabin (Commercial Airplanes). The pressurization of the cabin allowed the aircraft to fly at higher altitudes, at higher speeds and with improved fuel efficiency. The first two airlines to order the Boeing 307 Stratoliner were Pan Am and the Trans World Airlines (TWA).

Aircraft cabin (future)

Most of the future aircraft cabin designs consist of flying “wing type” designs which would house the passengers inside the wing to increase the efficiency of the airplane. Currently, all pressurized aircraft cabins have round shape as the aircraft manufactures are researching looking for a ways to overcome the challenges of pressurizing non-cylindrical areas (Larson, 2012).
