<div class="modal__text">
A wide-body aircraft is a larger airliner usually configured with multiple
aisles and a fuselage diameter of more than 5 metres (16 ft), allowing at
least seven-abreast seating and often more travel classes.

<p><dd>- The A380 is offered with the Rolls-Royce Trent 900 (A380-841/-842) or the Engine Alliance GP7000 (A380-861) turbofan engines.</dd></p>
<dd>- The Trent 900 is a combination of the 3 m (118 in) fan and scaled IP compressor of the 777-200X/300X Trent 8104 technology demonstrator derived from the Boeing 777's Trent 800, and the Airbus A340-500/600's Trent 500 core.</dd>
<dd>- The GP7200 HP core technology is derived from GE's GE90 and its LP sections are based on the PW4000 expertise.</dd>
<dd>- At its launch in 2000, engine makers assured Airbus it was getting the best level of technology and they would be state-of-the-art for the next decade, but three years later Boeing launched the 787 Dreamliner with game-changing technology and 10% lower fuel burn than the previous generation, to the dismay of John Leahy</dd></p>

<dd>- The A380 was initially offered in two models: the A380-800 and the A380F.
</dd><dd>- The A380-800's original configuration carried 555 passengers in a three-class configuration or 853 passengers (538 on the main deck and 315 on the upper deck) in a single-class economy configuration.</dd><dd>- The Boeing 747-400 experiences the least degradation in
performance, making it safer during an engine failure.</dd><dd>- Then in May 2007, Airbus began marketing a configuration with 30 fewer passengers (525 total in three classes)—traded for 200 nmi (370 km) more range—to better reflect trends in premium-class accommodation.</dd>

</p>
<p><dd>- The second model, the A380F freighter, would have carried 150 t (330,000 lb) of cargo over a range of 5,600 nmi (10,400 km).[153] Freighter development was put on hold as Airbus prioritised the passenger version, and all orders for freighters were cancelled.</dd></p>

<p>
<dd>- In mid-1988, Airbus engineers led by Jean Roeder began work in secret on the development of an ultra-high-capacity airliner (UHCA), both to complete its own range of products and to break the dominance that Boeing had enjoyed in this market segment since the early 1970s with its 747.</dd>
<dd>- Lockheed was exploring the possibility for a Very Large Subsonic Transport</dd>
<dd>Roeder was given approval for further evaluations of the UHCA after a formal presentation to the President and CEO in June 1990.</dd>

<dt>Wings</dt>

<div class="modal__text">
<p><dd> - The A380's wings are sized for a maximum takeoff weight (MTOW) over 650 tonnes to accommodate these future versions, albeit with some internal strengthening required on the A380F freighter. </dd><dd>- The optimal wingspan for this weight is about 90 m (300 ft), but airport restrictions have limited it to less than 80 m (260 ft), thereby lowering the aspect ratio to 7.8 which reduces fuel efficiency by about 10% and increases operating costs a few percent, given that fuel costs constitute about 50% of the cost of long-haul aeroplane operation.</dd></p>
</div>
<div class="modal__subhead">
<dt>Materials</dt>
</div>
<div class="modal__text">
<p><dd>- While most of the fuselage is made of aluminium alloys, composite materials comprise more than 20% of the A380's airframe.</dd><dd>- Carbon-fibre reinforced plastic, glass-fibre reinforced plastic and quartz-fibre reinforced plastic are used extensively in wings, fuselage sections (such as the undercarriage and rear end of fuselage), tail surfaces, and doors.</dd><dd>- The A380 is the first commercial airliner to have a central wing box made of carbon–fibre reinforced plastic. It is also the first to have a smoothly contoured wing cross–section. The wings of other commercial airliners are partitioned span-wise into sections. This flowing continuous cross section reduces aerodynamic drag. Thermoplastics are used in the leading edges of the slats.

<div class="modal__text">
<p><dd>- Airbus used similar cockpit layout, procedures and handling characteristics to other Airbus aircraft, reducing crew training costs. The A380 has an improved glass cockpit, using fly-by-wire flight controls linked to side-sticks</dd><dd>- The cockpit has eight 15 by 20 cm (5.9 by 7.9 in) liquid crystal displays, all physically identical and interchangeable; comprising two primary flight displays, two navigation displays, one engine parameter display, one system display and two multi-function displays. The MFDs were introduced on the A380 to provide an easy-to-use interface to the flight management system—replacing three multifunction control and display units.</dd>

<p><dd>- Power-by-wire flight control actuators have been used for the first time in civil aviation to back up primary hydraulic actuators. Also, during certain manoeuvres they augment the primary actuators</dd><dd>- They have self-contained hydraulic and electrical power supplies. Electro-hydrostatic actuators (EHA) are used in the aileron and elevator, electric and hydraulic motors to drive the slats as well as electrical backup hydrostatic actuators (EBHA) for the rudder and some spoilers.</dd></dl>
