Business class is almost replacing first class: 70% of 777s had first-class cabins before 2008 while 22% of new 777s and 787s had one in 2017.Full-flat seats in business-class rose from 65% of 777 deliveries in 2008 to nearly 100% of the 777s and 787s delivered in 2017, excepted for low-cost carriers having 10% premium cabin on their widebodies.

The aircraft design process is a loosely defined method used to balance many competing and demanding requirements to produce an aircraft that is strong, lightweight, economical and can carry an adequate payload while being sufficiently reliable to safely fly for the design life of the aircraft.
An aircraft seat map or seating chart is a diagram of the seat layout inside a passenger airliner. They are often published by airlines for informational purposes and are of use to passengers for selection of their seat at booking or check-in.
The parts are sent to the main plant of the plane company, where the production line is located. In the case of large planes, production lines dedicated to the assembly of certain parts of the plane can exist, especially the wings and the fuselage. [55] [56] When complete, a plane is rigorously inspected to search for imperfections and defects.
[note 1] In a flying boat hull or floatplane float, the longitudinal line of sharp change in cross-section where the bottom plane meets the sidewall is an example of a chine. On some supersonic aircraft a chine extends sideways for some distance, with a very sharp edge blending in with the main wing leading edge root.
The Kline–Fogleman airfoil or KF airfoil is a simple airfoil design with single or multiple steps along the length of the wing. It was originally devised in the 1960s for paper airplanes. In the 21st century the KF airfoil has found renewed interest among hobbyist builders of radio-controlled aircraft, due to its simplicity of construction. [1]
The wing root fairing of an American Aviation AA-1 Yankee. An aircraft fairing is a structure whose primary function is to produce a smooth outline and reduce drag. [1]These structures are covers for gaps and spaces between parts of an aircraft to reduce form drag and interference drag, and to improve appearance.
