Avionics Bay
Avionics bay, also known as E&E bay or electronic equipment bay in aerospace engineering is known as compartment in an aircraft that houses the avionics and other electronic equipment, such as flight control computers, navigation systems, communication systems, and other electronic equipment essential for the operation. It is designed to be modular with individual components that can be easily removed and replaced in case of failure and is designed to be highly reliable and fault-tolerant with various backup systems. In larger commercial airplanes, the main avionics compartment is typically located in the forward section of the aircraft under the cockpit. Purpose of its location is to provide easy access to the avionics and other electronic equipment for maintenance and repair. For example, on larger aircraft such as the Boeing 747-400, the avionics bays are divided into 3 parts - the main equipment center (MEC), the center equipment center (CEC) and the aft equipment center (AEC) ...

Flight Management Computer
A flight management system (FMS) is a fundamental component of a modern airliner's avionics. An FMS is a specialized computer system that automates a wide variety of in-flight tasks, reducing the workload on the flight crew to the point that modern civilian aircraft no longer carry flight engineers or navigators. A primary function is in-flight management of the flight plan. Using various sensors (such as GPS and INS often backed up by radio navigation) to determine the aircraft's position, the FMS can guide the aircraft along the flight plan. From the cockpit, the FMS is normally controlled through a Control Display Unit (CDU) which incorporates a small screen and keyboard or touchscreen. The FMS sends the flight plan for display to the Electronic Flight Instrument System (EFIS), Navigation Display (ND), or Multifunction Display (MFD). The FMS can be summarised as being a dual system consisting of the Flight Management Computer (FMC), CDU and a cross talk bus. The modern FMS wa ...

Aircraft Systems
Aircraft systems are those required to operate an aircraft efficiently and safely. Their complexity varies with the type of aircraft. Aircraft software systems Aircraft software systems control, manage, and apply the subsystems that are engaged with avionics on board an aircraft. Flight control systems Flight control systems can be manually operated or powered. They are designed to move the flight control surfaces or swashplate, allowing the pilot to maintain or change attitude as required. Landing gear system Landing gear systems for larger aircraft are usually hydraulic for powered retraction/extension of the main legs and doors and also for braking. Anti-skid systems are used to provide maximum braking performance. Hydraulic system A hydraulic system is required for high speed flight and large aircraft to convert the crews' control system movements to surface movements. The hydraulic system is also used to extend and retract landing gear, operate flaps and slats, operat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft Instruments
Flight instruments are the instruments in the cockpit of an aircraft that provide the pilot with data about the flight situation of that aircraft, such as altitude, airspeed, Variometer, vertical speed, heading and much more other crucial information in flight. They improve safety by allowing the pilot to fly the aircraft in level flight, and make turns, without a reference outside the aircraft such as the horizon. Visual flight rules (VFR) require an airspeed indicator, an altimeter, and a compass or other suitable magnetic direction indicator. Instrument flight rules (IFR) additionally require a gyroscopic pitch-bank (artificial horizon), direction (directional gyro) and rate of turn indicator, plus a slip-skid indicator, adjustable altimeter, and a clock. Flight into instrument meteorological conditions (IMC) require radio navigation instruments for precise takeoffs and landings. The term is sometimes used loosely as a synonym for cockpit, cockpit instruments as a whole, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Executive Decision
''Executive Decision'' is a 1996 American action thriller film directed by Stuart Baird (in his directorial debut) and written by Jim Thomas and John Thomas, who also produced the film with Joel Silver. It stars Kurt Russell, Steven Seagal, Halle Berry, John Leguizamo, Oliver Platt, Joe Morton, David Suchet and B.D. Wong. It depicts the rescue of an airliner hijacked by terrorists, by a small team placed on the plane in mid-flight. The film was released in the United States on March 15, 1996, by Warner Bros. It grossed $122 million against a $55 million budget. Plot In May 1995, Lieutenant Colonel Austin Travis leads an unsuccessful Special Forces black ops raid on a Chechen mafia safe house in Trieste, Italy, to recover a stolen Soviet nerve agent, DZ-5. Three months later, Oceanic Airlines Flight 343, a Boeing 747-200, leaves Athens bound for Washington, D.C., with more than 400 passengers aboard including Nagi Hassan, lieutenant of the imprisoned terrorist lea ...

Uncontrolled Decompression
An uncontrolled decompression is an undesired drop in the pressure of a sealed system, such as a pressurised aircraft cabin or hyperbaric chamber, that typically results from human error, structural failure, or impact, causing the pressurised vessel to vent into its surroundings or fail to pressurize at all. Such decompression may be classed as ''explosive, rapid'', or ''slow'': * Explosive decompression (ED) is violent and too fast for air to escape safely from the lungs and other air-filled cavities in the body such as the sinuses and eustachian tubes, typically resulting in severe to fatal barotrauma. * Rapid decompression may be slow enough to allow cavities to vent but may still cause serious barotrauma or discomfort. * Slow or gradual decompression occurs so slowly that it may not be sensed before hypoxia sets in. Description The term ''uncontrolled decompression'' here refers to the unplanned depressurisation of vessels that are occupied by people; for example, a pressu ...

Cockpit Voice Recorder
A flight recorder is an electronic recording device placed in an aircraft for the purpose of facilitating the investigation of aviation accidents and incidents. The device may often be referred to colloquially as a "black box", an outdated name which has become a misnomer—they are now required to be painted Safety orange, bright orange, to aid in their recovery after accidents. There are two types of flight recording devices: the flight data recorder (FDR) preserves the recent history of the flight through the recording of dozens of parameters collected several times per second; the cockpit voice recorder (CVR) preserves the recent history of the sounds in the cockpit, including the conversation of the pilots. The two devices may be combined into a single unit. Together, the FDR and CVR objectively document the aircraft's flight history, which may assist in any later investigation. The two flight recorders are required by international regulation, overseen by the Internation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mode Control Panel
In aviation, the mode control panel (MCP) is an instrument panel that controls an advanced autopilot An autopilot is a system used to control the path of a vehicle without requiring constant manual control by a human operator. Autopilots do not replace human operators. Instead, the autopilot assists the operator's control of the vehicle, allow ... and related systems such as an automated flight-director system (AFDS). The MCP contains controls that allow the crew of the aircraft to select which parts of the aircraft's flight are to be controlled automatically. In modern MCPs, there are many different modes of automation available. The MCP can be used to instruct the autopilot to hold a specific altitude, to change altitudes at a specific rate, to hold a specific heading, to turn to a new heading, to follow the directions of a flight management computer (FMC), and so on. The MCP is actually independent of the autopilot—it simply sets the mode in which the autopilot ope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerospace Engineering
Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. It has two major and overlapping branches: aeronautical engineering and astronautical engineering. Avionics engineering is similar, but deals with the electronics side of aerospace engineering. "Aeronautical engineering" was the original term for the field. As flight technology advanced to include vehicles operating in outer space, the broader term "aerospace engineering" has come into use. Aerospace engineering, particularly the astronautics branch, is often colloquially referred to as "rocket science". Overview Flight vehicles are subjected to demanding conditions such as those caused by changes in atmospheric pressure and temperature, with structural loads applied upon vehicle components. Consequently, they are usually the products of various technological and engineering disciplines including aerodynamics, air propulsion, avionics, materials science, st ...

Autothrottle
An autothrottle (automatic throttle; also known as autothrust, A/T, or A/THR) is a system that allows a pilot to control the power setting of an aircraft's engines by specifying a desired flight characteristic, rather than manually controlling the fuel flow. The autothrottle can greatly reduce the pilots' workload and help conserve fuel and extend engine life by metering the precise amount of fuel required to attain a specific target indicated air speed, or the assigned power for different phases of flight. A/T and AFDS (Auto Flight Director Systems) can work together to fulfill the whole flight plan. Working modes There are two parameters that an A/T can maintain, or try to attain: speed and thrust. In speed mode the throttle is positioned to attain a set target speed, subject to safe operating margins. For example, if the pilot selects a target speed which is slower than stall speed, the autothrottle system maintains a speed above the stall speed. In the thrust mode the engi ...

Autopilot
An autopilot is a system used to control the path of a vehicle without requiring constant manual control by a human operator. Autopilots do not replace human operators. Instead, the autopilot assists the operator's control of the vehicle, allowing the operator to focus on broader aspects of operations (for example, monitoring the trajectory, weather and on-board systems). When present, an autopilot is often used in conjunction with an autothrottle, a system for controlling the power delivered by the engines. An autopilot system is sometimes Colloquialism, colloquially referred to as ''"George"'' (e.g. ''"we'll let George fly for a while"; "George is flying the plane now".''). The etymology of the nickname is unclear: some claim it is a reference to American inventor George De Beeson (1897–1965), who patented an autopilot in the 1930s, while others claim that Royal Air Force pilots coined the term during World War II to symbolize that their aircraft technically belonged to Ki ...
