other new technology on A380:
- An A380 innovation is the open Integrated Modular Avionics (IMA) concept, which will help to reduce support costs and make upgrades easier. Applicable to multiple aircraft functions, IMA includes elements developed by Rockwell Collins (high-speed bus switches), Thales Avionics (IMA modules) and internal Airbus supplier EYY (IMA modules).
-The Honeywell-developed surveillance system also represents a leap in capability and design.
- The avionics systems are built on large computing resources and a two-way, deterministic, 100-megabit/sec backbone. This avionics full-duplex (AFDX) switched Ethernet bus will move massive volumes of data, enabling the manipulation of large databases to drive the high-resolution, real-time Thales displays. Yet there is still margin for growth, to incorporate new features and functions.
- The cockpit display system (CDS) has also been upgraded, it will feature eight 6-by-8-inch liquid crystal displays (LCDs), rather than six 6-by-6-inch displays. These comprise two primary flight displays (PFDs), two navigation displays, one engine parameter display, one system display and two multifunction displays (MFDs). All the displays are identical, interchangeable and potentially interactive.
- New is the vertical position/weather display, in the lower portion of the navigation display. It presents a vertical profile of the flight path, with altitude on the vertical axis and distance on the horizontal axis. Terrain information provided by the terrain awareness warning system (TAWS) database is painted in brown along the bottom, the flight path is projected in green, and the aircraft icon is drawn in yellow.
New generation FMS. The interaction with the FMS system through the navigation screen. Integral to this change is the Thales-designed KCCU, which includes a keyboard with dedicated FMS and other function keys and a QWERTY pad, plus a hand rest with a trackball for moving the cursor on the MFD and a mouse button for clicking the cursor. The KCCU also features left and right arrow keys to move the cursor from screen to screen, mainly between the nav screen, the MFD and the system display containing the ATC mailbox.
The pilot will be able to interact with the FMS through the navigation screen to modify waypoints, viewing the temporary (and permanent) flight plans. The navigation display will feature menus of choices, allowing pilots to delete a waypoint or insert a hold, for example, rather than interact with lists of data on an MCDU.
- just like 747 all structurally parts dimensioned for loads never experiences before
- a new hydraulic system, the A380's hydraulic systems will have an increased pressure of 5,000 pounds per square inch (psi), as opposed to the traditional 3,000 psi.T his increase in pressure allows the necessary power to be transmitted with smaller piping and hydraulic components
- new materials such as Glare and carbon fibre reinforced plastics (CFRP) thermoplastics and advanced aluminium alloys. An estimated 40 per cent of the aircraft's structure and components will thus be manufactured from the latest generation of carbon composites and advanced metallic materials, which, besides being lighter than traditional materials, offer significant advantages in terms of operational reliability, maintainability and ease of repair.
- a dual architecture for the flight control system has been implemented, featuring four independent primary flight control systems with two different configurations. Two of these systems use a conventional hydraulic actuation system whereas the other two feature local electro-hydraulic actuators for the control surfaces. The aircraft can be controlled using any one of these four systems
