Runway Awareness And Advisory System
The Runway Awareness and Advisory System (RAAS) is an electronic detection system manufactured by Honeywell Aerospace, that notifies aircraft flight crews on the ground of their position relative to their allocated runway. Overview According to Honeywell, who developed RAAS, runway incursions are a leading cause of aviation accidents and fatalities, costing approximately $1 billion annually. RAAS functions by providing audible alerts to confirm runway identification, and also provides an aural alarm if it detects undue acceleration (indicating an attempt to take off) while the aircraft is on any taxiway instead of a designated runway. Its function is possible by a software enhancement to the aircraft's terrain awareness and warning system (TAWS) or enhanced ground proximity warning system (EGPWS). Entrance into service Alaska Airlines announced in September 2008 that its entire airline fleet of Boeing 737s will be equipped with RAAS by the end of September. That will be the f ...

Honeywell Aerospace
Honeywell Aerospace is a manufacturer of aircraft engines and avionics, as well as a producer of auxiliary power units (APUs) and other aviation products. Headquartered in Phoenix, Arizona, it is a division of the Honeywell International conglomerate. It generates approximately $10 billion in annual revenue from a 50/50 mix of commercial and defense contracts. The company experienced a boom during World War II, when it equipped bomber planes with avionics and invented the autopilot. After the war, it transitioned to a heavier focus on peacetime applications. Today, Honeywell produces space equipment, turbine engines, auxiliary power units, brakes, wheels, synthetic vision, runway safety systems, and other avionics. A Honeywell APU was used in the notable emergency landing of US Airways Flight 1549, and a Honeywell blackbox survived under sea for years, thus exceeding by far its specified limits to reveal the details of the crash of Air France Flight 447. The company was als ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Runway
According to the International Civil Aviation Organization (ICAO), a runway is a "defined rectangular area on a land aerodrome prepared for the landing and takeoff of aircraft". Runways may be a man-made surface (often asphalt concrete, asphalt, concrete, or a mixture of both) or a natural surface (sod, grass, soil, dirt, gravel, ice, sand or road salt, salt). Runways, as well as taxiways and Airport apron, ramps, are sometimes referred to as "tarmac", though very few runways are built using Tarmacadam, tarmac. Takeoff and landing areas defined on the surface of water for seaplanes are generally referred to as waterways. Runway lengths are now International Civil Aviation Organization#Use of the International System of Units, commonly given in meters worldwide, except in North America where feet are commonly used. History In 1916, in a World War I war effort context, the first concrete-paved runway was built in Clermont-Ferrand in France, allowing local company Michelin to ...

Runway Incursion
A runway incursion is an Aviation accidents and incidents, aviation incident involving improper positioning of vehicles or people on any runway, airport runway or its Critical_area_(aeronautics), protected area. When an incursion involves an ''active'' runway being used by arriving or departing aircraft, the potential for a collision hazard or Instrument landing system, Instrument Landing System (ILS) interference can exist. At present, various runway safety technologies and processes are commonly employed to reduce the risk and potential consequences of such an event. Definition The internationally-accepted definition of a runway incursion is: In the United States, the FAA classifies runway incursions into 3 types, with 5 levels of severity: Analysis Formal study of runway incursions began in the 1980s, following several high-profile Near miss (safety), near misses and fatal collisions of Airliner, airliners operating on airport surfaces. One of the earliest reports on ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Takeoff
Takeoff is the phase of flight in which an aerospace vehicle leaves the ground and becomes airborne. For aircraft traveling vertically, this is known as liftoff. For aircraft that take off horizontally, this usually involves starting with a transition from moving along the ground on a runway. For balloons, helicopters and some specialized fixed-wing aircraft (VTOL aircraft such as the Harrier and the Bell Boeing V22 Osprey), no runway is needed. Horizontal Power settings For light aircraft, usually full power is used during takeoff. Large transport category (airliner) aircraft may use a reduced power for takeoff, where less than full power is applied in order to prolong engine life, reduce maintenance costs and reduce noise emissions. In some emergency cases, the power used can then be increased to increase the aircraft's performance. Before takeoff, the engines, particularly piston engines, are routinely run up at high power to check for engine-related problems. The airc ...

Taxiway
A taxiway is a path for aircraft at an airport connecting runways with aprons, hangars, terminals and other facilities. They mostly have a hard surface such as asphalt or concrete, although smaller general aviation airports sometimes use gravel or grass. Most airports do not have a specific speed limit for taxiing (though some do). There is a general rule on safe speed based on obstacles. Operators and aircraft manufacturers might have limits. Typical taxi speeds are 20–30 knots (37–56 km/h; 23–35 mph). High-speed exit Busy airports typically construct high-speed or rapid-exit taxiways to allow aircraft to leave the runway at higher speeds. This allows the aircraft to vacate the runway quicker, permitting another to land or take off in a shorter interval of time. This is accomplished by reducing the angle the exiting taxiway intercepts the runway at to 30 degrees, instead of 90 degrees, thus increasing the speed at which the aircraft can exit the runway onto the taxiway. ...

Terrain Awareness And Warning System
In aviation, a terrain awareness and warning system (TAWS) is generally an on-board system aimed at preventing unintentional impacts with the ground, termed "controlled flight into terrain" accidents, or CFIT.Federal Aviation AdministrationInstallation of Terrain Awareness and Warning System (TAWS) Approved for Part 23 Airplanes 14 June 2000 The specific systems currently in use are the ground proximity warning system (GPWS) and the enhanced ground proximity warning system (EGPWS). The U.S. Federal Aviation Administration (FAA) introduced the generic term ''TAWS'' to encompass all terrain-avoidance systems that meet the relevant FAA standards, which include GPWS, EGPWS and any future system that might replace them. As of 2007, 5% of the world's commercial airlines still lacked a TAWS. A study by the International Air Transport Association examined 51 accidents and incidents and found that pilots did not adequately respond to a TAWS warning in 47% of cases. Several factors can s ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Aviation Week & Space Technology
''Aviation Week & Space Technology'', often abbreviated ''Aviation Week'' or ''AW&ST'', is the flagship magazine of the Aviation Week Network. The weekly magazine is available in print and online, reporting on the aerospace, defense and aviation industries, with a core focus on aerospace technology. It has a reputation for its contacts inside the United States military and industry organizations. ''Aviation Week'' was a favorite conduit for defense-related companies and labs to leak information to the public as part of their policy by press release efforts. This led to it being informally referred to "Aviation Leak and Space Mythology". History The magazine was first published in August 1916. Early editors Ladislas d'Orsy and Donald W. McIlhiney (1921 to 25) were Quiet Birdmen. Publisher (1927 to 29) Earl D. Osborn was also a Quiet Birdman. With the coming of the Space Age, the current title was adopted in 1960. Other titles the magazine has held include ''Aviation & Aircraft ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
