The Intel APIC Architecture is well known for producing a huge amount of interrupt latency jitter.

* Global System Interrupt in Advanced Configuration and Power Interface for Intel APIC Architecture.

The Intel APIC Architecture is a system of advanced programmable interrupt controllers ( APICs ) designed by Intel for use in symmetric multiprocessor ( SMP ) computer systems.

There is typically one I / O APIC for each peripheral bus in the system.

Newer systems use the system bus for communication between all APIC components.

These APICs support a programming interface for up to 255 physical hardware IRQ lines per APIC, with a typical system implementing support for only around 24 total hardware lines.

An auxiliary power unit ( APU ) is a device on a vehicle that provides energy for functions other than propulsion.

If the APU or its electrical generator is not available, the aircraft cannot be released for ETOPS flight and is forced to take a longer non-ETOPS route.

A typical gas turbine APU for commercial transport aircraft comprises three main sections:

The power section is the gas generator portion of the engine and produces all the shaft power for the APU.

Some APU designs use a combination starter / generator for APU starting and electrical power generation to reduce complexity.

A refrigerated or frozen food semi trailer or train car may be equipped with an independent APU and fuel tank to maintain low temperatures while in transit, without the need for an external transport-supplied power source.

The most common APU for a commercial truck is a small diesel engine with its own cooling system, heating system, generator or alternator system with or without inverter, and air conditioning compressor, housed in an enclosure and mounted to one of the frame rails of a semi-truck.

The APU generator engine is a fraction of the main engine's size and uses a fraction of the fuel ; some models can run for eight hours on one US gallon (≈ 4 litres ) of diesel.

The generator also powers the main engine's block and fuel system heaters, so the main engine can be started easily right before departure if the APU is allowed to run for a period beforehand.

Initially Anglia Polytechnic University ( APU ), it retained the word ' polytechnic ' in its title because " the term ' polytechnic ' still had value to students and their potential employers, symbolising as it did the sort of education that they were known for – equipping students with effective practical skills for the world of work " although in 2000 there was some self-doubt about including the term ' polytechnic ' – it was the last university in the country to have done so.

By using the APU ( powered by a turbine ) to energize a Chorus electric motor mounted in the landing gear for ground movement, aircraft will be operating in a hybrid configuration where the main engines are used only for take off, landing, and flight.

It was next scheduled for 4 November, but was again scrubbed when high oil pressures were discovered in two of the three Auxiliary Power Units ( APU ) that controlled the orbiter's hydraulic system.

Since the module is mostly self-contained, the state of the APU can be saved as an. SPC file, and can be emulated in a stand-alone manner to play back all game music ( except for a few games that constantly stream their samples from ROM ).

With Kenneth Craik he was responsible for setting up the Medical Research Council's Applied Psychology Research Unit ( APU ) at Cambridge in 1944, becoming Director of the unit after Craik's early death in 1945.

A cooling system for Auxiliary Power Unit ( APU ) 2 failed to activate during an on-orbit test.

APU 2 was still available for use in landing.

Bleed air for starting is provided by an on board auxiliary power unit ( APU ) or an external huffer if the APU is inoperative.

Because the aircraft has no bleed air powered engine starters, and no requirement for bleed air for cabin pressurization during flight, there is no need to have the APU drive a load compressor to supply bleed air to the aircraft during a period of engine loss, or on the ground at the start of each flight.

In many modern airliners aircraft, for example all Airbus aircraft developed from the 1980s, the joystick has received a new lease on life for flight control in the form of a " sidestick " — a controller similar to a games joystick, but which is used to control the flight, replacing the traditional yoke.

Test carriers were so far the Airbus A300 for short duration parabolic flights and the sounding rocket test campaigns REXUS3-REGINA and REXUS4-MIRIAM for longer duration flight tests under free space conditions.

To meet growing demands for passenger and cargo capacity, in 2005 these airlines significantly expanded their fleets with orders placed for additional Boeing and Airbus aircraft expected to be delivered by 2010.

Aeronautics offers ; airborne systems, related subsystems, Unmanned Aerial Systems ( UAS ) and aerostructures The business area Aeronautics is responsible for airframe structures for JAS 39 Gripen, and whole sections for Airbus, Boeing and NH90.

Schiphol is equipped with 18 double jetway gates in preparation for airlines introducing the Airbus A380.

On 6 September 2012 the company opened a new column-free three-bay hangar for Base Maintenance works of narrow-body aircraft, such as Boeing 737 and Airbus A320.

Civilian work increased in the form of participating in design and manufacture of parts for Airbus aircraft, most notably A380 spoilers.

* October 28 – The Airbus A300 flies for the first time.

On November 12, 2001, about 09: 16 eastern standard time, American Airlines flight 587, N14053, an Airbus A300B4-605R delivered in 1988 with a seating configuration for 267 passengers ( 16 first-class seats and 251 economy-class seats ) and powered by two General Electric CF6-80C2A5 engines, crashed into Belle Harbor, a New York City residential area, shortly after takeoff from John F. Kennedy International Airport, New York.

Airbus and American are currently disputing the extent to which the two parties are responsible for the disaster.

In 1979 BAe officially joined Airbus, the UK having previously withdrawn support for the consortium in April 1969.

The Boeing 747 and Airbus A380 are the only airliners in production which are too heavy ( more than 400 tons maximum takeoff weight ) for just two engines.

The international market for middle-sized and large-sized airliners is now divided between Airbus and Boeing, although Russian / former Soviet manufacturers still sell significant numbers of airliners to their traditional markets.

It is also involved in two major joint ventures, the Engine Alliance with GE which manufactures engines for the Airbus A380, and International Aero Engines company with Rolls-Royce, MTU Aero Engines, and the Japanese Aero Engines Corporation which manufactures engines for the Airbus A320 and the McDonnell Douglas MD-90 aircraft.
