Airbus A321 in the context of Climb (aeronautics)

An assembly line, often called progressive assembly, is a manufacturing process where the unfinished product moves in a direct line from workstation to workstation, with parts added in sequence until the final product is completed. By mechanically moving parts to workstations and transferring the unfinished product from one workstation to another, a finished product can be assembled faster and with less labor than having workers carry parts to a stationary product.

Assembly lines are common methods of assembling complex items such as automobiles and other transportation equipment, household appliances and electronic goods.

Aircraft maintenance is the performance of tasks required to ensure the continuing airworthiness of an aircraft or aircraft part, including overhaul, inspection, replacement, defect rectification, and the embodiment of modifications, compliance with airworthiness directives and repair.

In aeronautics, a spoiler (sometimes called a lift spoiler or lift dumper) is a device which increases the drag and decreases the lift of an airfoil in a controlled way. Most often, spoilers are hinged plates on the top surface of a wing that can be extended upward into the airflow to spoil the streamline flow. By so doing, the spoiler creates a controlled stall over the portion of the wing behind it, greatly reducing the lift of that wing section.

Spoilers differ from airbrakes in that airbrakes are designed to increase drag without disrupting the lift distribution across the wing span, while spoilers disrupt the lift distribution as well as increasing drag. However, flight spoilers are routinely referred to as "speed brakes" on transport aircraft by pilots and manufacturers, despite significantly reducing lift.

An aerospace manufacturer is a company or individual involved in the various aspects of designing, building, testing, selling, and maintaining aircraft, aircraft parts, missiles, rockets, or spacecraft. Aerospace is a high technology industry.

The aircraft industry is the industry supporting aviation by building aircraft and manufacturing aircraft parts for their maintenance. This includes aircraft and parts used for civil aviation and military aviation. Most production is done pursuant to type certificates and Defense Standards issued by a government body. This term has been largely subsumed by the more encompassing term: "aerospace industry".

The Airbus A320 family is a series of narrow-body airliners developed and produced by Airbus, and is the best-selling airliner ever built. The A320 aircraft programme was launched in March 1984, first flew on 22 February 1987, and was introduced in April 1988 by Air France.The first member of the family was followed by the stretched A321 (first delivered in January 1994), the shorter A319 (April 1996), and the shortest variant, the A318 (July 2003).Final assembly takes place in Toulouse in France; Hamburg in Germany; Tianjin in China since 2009; and Mobile, Alabama, in the United States since April 2016.

The twinjet has a six-abreast economy cross-section and came with either CFM56-5A or -5B, or IAE V2500 turbofan engines, except the A318. The A318 has either two CFM56-5B engines or a pair of PW6000 engines in place of the IAE V2500.The family pioneered the use of digital fly-by-wire and side-stick flight controls in airliners.Variants offer maximum take-off weights from 68 to 93.5 tonnes (150,000 to 206,000 lb), to cover a 5,740–6,940 kilometres; 3,570–4,320 miles (3,100–3,750 nmi) range.The 31.4 m (103 ft) long A318 typically accommodates 107 to 132 passengers.The 124-156 seat A319 is 33.8 m (111 ft) long.The A320 is 37.6 m (123 ft) long and can accommodate 150 to 186 passengers.The 44.5 m (146 ft) A321 offers 185 to 230 seats.The Airbus Corporate Jets are modified business jet versions of the standard commercial variants.
