AIRCRAFT CABIN LAYOUT
- AIRLINE AIRCRAFT SEATING CHARTS
Airline cabins are frequently classified as narrow-body if there is a single aisle with seats on either side, or wide-body if there are two aisles with a block of seats between them in addition to the seats on the side.
The number of seats abreast is affected by the aircraft width. On very small aircraft such as the Beechcraft 1900 there are only individual seats on each side of the aisle (1+1 seating). The widest narrow body aircraft such as the Airbus A320 and Boeing 737 have six abreast seating in a 3+3 layout. Asymmetrical layouts also exist, the Embraer Regional Jets have 1+2 seating while the Douglas DC-9 aircraft typically feature 2+3 seating.
On wide body-aircraft the center block of seats between the aisles can have as many as 5 seats on planes like the layout on some McDonnell Douglas DC-10 and Boeing 777 aircraft, although Boeing recommends the 3+3+3 over the 2+5+2 layout. Very wide planes such as the Boeing 747 or the Airbus A380 have ten seats abreast, typically in a 3+4+3 layout, although this layout is also sometimes used as a high density layout on aircraft normally seating nine abreast, such as the 777 or DC-10.
Window seats are located at the sides of the aircraft, and usually next to a window, although some aircraft have seat rows where there is a window missing. Window seats are preferred by passengers who want to have a view, or a wall which they can lean against. Passengers in seats adjacent to the aisle have the advantage of being able to leave the seat without having to clamber over the other passengers, and having an aisle they can stretch their legs into. If a seat block has three or more seats, there will also be middle seats which are unpopular because the passenger is sandwiched between two other passengers without advantages of either window or aisle seats. Middle seats are typically booked last.
On most commercial aircraft, seats are forward facing. There are exceptions. On military aircraft seats are frequently rearward facing. Southwest Airlines previously offered a few such seats on some aircraft, rearward facing seats are also common on business jets to provide a "conference" type layout. British Airways also has rearward-facing seats in its Club World (Intercontinental Business Class) Cabin. It has been argued that rearward facing seats are safer because in the event of a crash, the sudden deceleration will propel the passenger into a rearward facing seat instead of out of it. The force is therefore distributed over the entire seat back, instead of the straps of the seat belt. The argument against such seats has been based on passenger comfort, safety and cost. An argument against rearward seats has been that passengers who desire the natural layout of forward facing seats may be uncomfortable with a rearward layout. On the safety aspect, the argument has been that during a plane crash, debris such as luggage, will fly forward in the cabin, quite possibly into the passengers in rearward facing seats. On the cost aspect, rearward facing seats need additional strengthening which adds extra weight and therefore higher costs. |
