Airbus: Technologies & Innovations that Changed the Airline Industry

The A320 was the world’s first commercial jet to use a small joystick, also called a sidestick, to fly it instead of a normal yoke (a steering-wheel like device). This matched the new digital ‘fly-by-wire’ system, the first use of this in a civilian aircraft, which makes the A320 much easier and safer to fly.

 

The A320 also has a full “glass-cockpit”, where most instruments in the cockpit (the front part of the plane where the pilot is) have been replaced by television screens. Most of the technology first used on the A320 has been used in other Airbus aircraft made afterwards. Other manufacturers, like Boeing, have also used much of the technology like a glass-cockpit and fly-by-wire in the Boeing 777.

 

In the same way we have been able to shorten the  A320 to create the A319, the most economic member of the family. These three aircrafts between them cover the needs of the airlines from 124 to 185 seats. This family design makes it easier for an airline to cope with daily or seasonal variations in traffic and keep maintenance costs down because of the fleet effect.

There are some most fact that has changed the market of Airbus in Aviation Industry-:

 

COMFORT

The family effect is all the greater because the initial design was right.

For passengers, this means an aircraft that is comfortable and convenient in every class. The versatility of the single aisle cabin lets operate as to match the market. First, business or economy class layouts as passenger demand requires. On regional flights, this means an equal comfort and useful flexibility for the airline.

 

AIRFRAME

The Airbus A320 family are low-wing cantilever monoplanes with a conventional empennage with a single vertical stabilizer and rudder. Its wing sweep is 25 degrees. Compared to other airliners of the same class, the A320 features a wider single-aisle cabin of 3.95 metres (156 in) outside diameter, compared to 3.8 m (148 in) of the Boeing 737 or 757, and larger overhead bins. Its cargo hold can accommodate Unit Load Devices containers.

 

The A320 airframe includes composite materials and aluminium alloys to save weight and reduce the total number of parts to decrease the maintenance costs. Its tail assembly is made almost entirely of such composites by CASA, who also builds the elevators, main landing gear doors, and rear fuselage parts.

 

FLIGHT DECK

It includes a full glass cockpit rather than the hybrid versions found in previous airliners. The A320’s flight deck is equipped with Electronic Flight Instrument System (EFIS) with side-stick controllers. The A320 features an Electronic Centralised Aircraft Monitor (ECAM) which gives the flight crew information about all the systems of the aircraft. The only analogue instruments were the radio-magnetic indicator and brake pressure indicator.

Since 2003, the A320 features liquid crystal display (LCD) units in its flight deck instead of the original cathode ray tube (CRT) displays. These include the main displays and the backup artificial.

 

 FLEXIBILITY

 The cabin intercommunication system makes it easy to vary cabin configuration. With the wide aisle, cabin crew and passengers can move more easily. A standard  A321 with 196 passengers has a turn round time of only 34 minutes and this reduces to 29 minutes with the wide aisle option, 11 minutes faster than the competition.

 

CABIN

In 2007, Airbus introduced a new enhanced, quieter cabin with better luggage storage and a more modern look and feel, and a new galley reducing weight, increasing revenue space and improving ergonomics and design for food hygiene and recycling. It offers a new air purifier with filters and a catalytic converter removing unpleasant smells from the air before it is pumped into the cabin and LEDs for ambience lighting and PSU.

Offering 10% more overhead bin volume, more shoulder room, a weight reduction, a new intercom and in-flight entertainment system, noise reduction and slimmer PSU, the enhanced Cabin can be retrofitted. The flight crew controls the cabin through touchscreen displays.

 

EFFICIENCY

 When the baggage isn’t left behind, the cargo compartments can be unloaded and reloaded well within the passenger turn round time. 70% of  A320 users have opted for the containerization system based on the LD 3 standard.  A wise choice when you consider the increasing proportion of an airline income that comes from freight. Although the  A321 is only 18% longer than the  A320, its underfloor capacity is 40% greater, room for three more containers.

NEW ENGINE OPTION

The A320neo (neo for new engine option) is a development launched on 1 December 2010, it made its first flight on 25 September 2014 and it was introduced by Lufthansa on 25 January 2016. Re-engined with CFM International LEAP-1A or Pratt & Whitney PW1000G engines and with large sharklets, it should be 15% more fuel efficient. Three variants are based on the previous A319, A320 and A321. Airbus received 6,031 orders by March 2018 and delivered 318 by May 2018. The original family is renamed A320ceo, for current engine option.

TECHNOLOGY

 Advanced composite materials and the best aluminum alloys produce a rugged yet light airframe. High structural efficiency directly reduces operating costs. The A321 and A319 are assembled in Germany at a purpose built Deutsch Airbus plant. Since potential corrosion problems are addressed at source, structural inspection programs are simplified reducing maintenance costs and enhancing resell value. More advanced technology can be seen in the wings which are lighter and optimized for computer control flight. Because of better aerodynamics, they made the  A320 and the  A321 the most fuel efficient commercial jets on the market.

 

RANGE

The  Airbus  A321 cost per passenger mile is by far the lowest in its category. The  A319 has the lowest fuel consumption. The engines too interface with the flight by wire controls and the autopilot system. The whole family has the same man machine interface.  The Primary Flight Display alone replaces six conventional electromagnetic instruments.
