TAWS
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 The Federal Aviation Administration (FAA) is a Federal government of the United States, U.S. federal government agency within the United States Department of Transportation, U.S. Department of Transportation that regulates civil aviation in t ... (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.

2010 Polish Air Force Tu-154 Crash
On 10 April 2010, a Tupolev Tu-154 aircraft operating Polish Air Force Flight 101 crashed near the Russian city of Smolensk, killing List of casualties of the Smolensk air disaster, all 96 people on board. Among the victims were the president of Poland, Lech Kaczyński, and his wife, Maria Kaczyńska, Maria; the former Polish government-in-exile, president of Poland-in-exile, Ryszard Kaczorowski; the chief of the Polish General Staff and other senior Polish military officers; the president of the National Bank of Poland; Polish government officials; 18 members of the Polish parliament; senior members of the Polish clergy; and relatives of victims of the Katyn massacre. The group was arriving from Warsaw to attend an event commemorating the 70th anniversary of the massacre, which took place not far from Smolensk. The pilots were attempting to land at Smolensk North Airport — a former military airbase — in thick fog, with visibility reduced to about . The aircraft descended f ...

Ground Proximity Warning System
A Ground Proximity Warning System (GPWS) is a system designed to alert pilots if their aircraft is in immediate danger of flying into the ground or an obstacle. The United States Federal Aviation Administration (FAA) defines GPWS as a type of terrain awareness and warning system (TAWS). More advanced systems, introduced in 1996, are known as enhanced ground proximity warning systems (EGPWS), a modern type of TAWS. History In the late 1960s, a series of controlled flight into terrain (CFIT) accidents took the lives of hundreds of people. A CFIT accident is one where a properly functioning airplane under the control of a fully qualified and certified crew is flown into terrain, water or obstacles with no apparent awareness on the part of the crew.Note: Original text copied from U.S. FAA Circular AC23-1.

American Airlines Flight 965
American Airlines Flight 965 was a regularly scheduled flight from Miami International Airport in Miami, Florida, to Alfonso Bonilla Aragón International Airport in Cali, Colombia. On December 20, 1995, the Boeing 757-200 flying this route ( registration ) crashed into a mountain in Buga, Colombia, around 9:40 pm killing 151 of the 155 passengers and all eight crew members. The crash was the first U.S.-owned 757 accident and is currently the deadliest aviation accident to occur in Colombia. It was also the deadliest accident involving a Boeing 757 at that time, but was surpassed by Birgenair Flight 301 which crashed seven weeks later with 189 fatalities. Flight 965 was the deadliest air disaster involving a U.S. carrier since the bombing of Pan Am Flight 103 in 1988. The Colombian Special Administrative Unit of Civil Aeronautics investigated the accident and determined it was caused by navigational errors by the flight crew. Aircraft The aircra ...

Runway Awareness And Advisory System
The Runway Awareness and Advisory System (RAAS) is an electronic detection system that notifies aircraft flight crews on the ground of their position relative to their allocated runway. It is a type of Runway Situation Awareness Tool (RSAT). Overview According to Honeywell Aerospace, who developed the original 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 b ...

Airborne Collision Avoidance System
An airborne collision avoidance system (ACAS, usually pronounced as ''ay-kas'') operates independently of ground-based equipment and air traffic control in warning pilots of the presence of other aircraft that may present a threat of collision. If the risk of collision is imminent, the system recommends a maneuver that will reduce the risk of collision. ACAS standards and recommended practices are mainly defined in annex 10, volume IV, of the Convention on International Civil Aviation. Much of the technology being applied to both military and general aviation today has been undergoing development by NASA and other partners since the 1980s. A distinction is increasingly being made between ACAS and ASAS (airborne separation assurance system). ACAS is being used to describe short-range systems intended to prevent actual metal-on-metal collisions. In contrast, ASAS is being used to describe longer-range systems used to maintain standard ''en route'' separation between aircraft ( ho ...

Controlled Flight Into Terrain
In aviation, a controlled flight into terrain (CFIT; usually ) is an aviation accidents and incidents, accident in which an airworthy aircraft, fully under pilot control, is unintentionally flown into the ground, a body of water or other obstacle. In a typical CFIT scenario, the aircrew, crew is unaware of the impending collision until impact, or it is too late to avert. The term was coined by engineers at Boeing in the late 1970s. Accidents where the aircraft is out of control at the time of impact, because of mechanical failure or pilot error, are classified instead as uncontrolled flight into terrain, or UFIT. Incidents resulting from the deliberate action of the person at the controls, such as a forced landing, an act of terrorism, or suicide by pilot, are also excluded from the definition of CFIT. According to Boeing in 1997, CFIT was a leading cause of airplane accidents involving the loss of life, causing over 9,000 deaths since the beginning of the commercial jet aircra ...

Avionics
Avionics (a portmanteau of ''aviation'' and ''electronics'') are the Electronics, electronic systems used on aircraft. Avionic systems include communications, Air navigation, navigation, the display and management of multiple systems, and the hundreds of systems that are fitted to aircraft to perform individual functions. These can be as simple as a searchlight for a police helicopter or as complicated as the tactical system for an airborne early warning platform. History The term "avionics" was coined in 1949 by Philip J. Klass, senior editor at ''Aviation Week & Space Technology'' magazine as a portmanteau of "aviation electronics". Radio communication was first used in aircraft just prior to World War I. The first Airborne radio relay, airborne radios were in zeppelins, but the military sparked development of light radio sets that could be carried by heavier-than-air craft, so that aerial reconnaissance biplanes could report their observations immediately in case they we ...

Technical Standard Order
A Technical Standard Order (TSO) is a minimum performance standard issued by the United States Federal Aviation Administration for specified materials, parts, processes, and appliances used on civil aircraft. Articles with TSO design approval are eligible for use on United States type certified products by following a much lighter process than similar non-TSO approved parts, provided the TSO standard meets the aircraft requirements. The TSO authorization (also called TSOA) or a letter of TSO Design Approval does not necessarily convey approval for installation. Similar standards are maintained by other aviation authorities. For example European Technical Standard Orders (ETSO) by EASA for the European Union, with limited reciprocal equivalence on a per-country basis. These often have the same numbers as FAA TSOs. For example, the FAA TSO for aviation headsets is C139. In the European Union, it is ETSO-C139. See also *Type certificate *Supplemental type certificate A supplement ...
