Blackwater 61 Crash
Blackwater 61 was the callsign of a CASA 212, registration N960BW, operated by Presidential Airways Inc, the aviation subsidiary of the private security contractor Blackwater USA, that crashed in the mountains of remote central Afghanistan on November 27, 2004. The turboprop airplane was carrying three military passengers and three members of the flight crew when it crashed. According to the NTSB investigative report of the accident, the Blackwater pilots were "behaving unprofessionally" and were "deliberately flying the nonstandard route low through the valley for fun." The accident contributed to the debate over the use of private military contractors in war-zones and Blackwater's hiring practices and standard operating procedures. Blackwater aircraft had been operating in Afghanistan under contract with the U.S. military to transport troops and supplies throughout the country. Five people aboard the aircraft died in the crash, while one later died awaiting rescue. Background ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CASA 212
The CASA C-212 Aviocar is a turboprop-powered STOL medium cargo aircraft designed and built by the Spanish aircraft manufacturer Construcciones Aeronáuticas SA (CASA). It is designed for use by both civil and military operators. The C-212 was developed during the 1960s in response to the Spanish Air Force's need to replace much of its transport aircraft fleet and was designed to perform numerous roles, including ambulance aircraft, paratroop carrier, and utility transport. The first prototype made its maiden flight on 26 March 1971, and an order was secured from the Spanish Air Force three years thereafter. Several other customers emerged, initially from the military sector but, due to the interest of civilian airliners, CASA developed a dedicated civil version of the C-212 as well. Production of the type at the Seville facility would continue for 40 years, with 483 aircraft produced. Indonesia emerged as a key early customer for the C-212. During 1975, the Indonesian a ...

Bombardier Dash-8
The De Havilland Canada DHC-8, commonly known as the Dash 8, is a series of turboprop-powered regional airliners, introduced by de Havilland Canada (DHC) in 1984. DHC was later bought by Boeing in 1988, then by Bombardier in 1992; then by Longview Aviation Capital in 2019, reviving the De Havilland Canada brand. Powered by two Pratt & Whitney Canada PW100s, it was developed from the Dash 7 with improved cruise performance and lower operational costs, but without STOL performance. Three sizes were offered: initially the 37–40 seat -100 until 2005 and the more powerful -200 from 1995, the stretched 50–56 seats -300 from 1989, both until 2009, and the 68–90 seats -400 from 1999, still in production. The QSeries are post-1997 variants fitted with active noise control systems. Development Initial development In the 1970s, de Havilland Canada had invested heavily in its Dash 7 project, concentrating on STOL and short-field performance, the company's traditional ...

Koh-i-Baba
The Baba Mountain range ( ps, بابا غر Bâbâ Ǧar; fa, کوه بابا Kōh-i Bābā; or Kūh-e Bābā; ''Kōh'' or ''Kūh'' meaning ′mountain′, ''Bābā'' meaning ′father′) is the western extension of the Hindu Kush, and the origin of Afghanistan's Kabul, Arghandab, Helmand, Farah, Hari, Murghab, Balkh, and Kunduz rivers. The mountain range is crowned by ''Foladi peak'' (or Shah Fuladi) rising 5048 m (some old maps and dictionaries: on universal_lexikon.de 5143 m) above sea level, and is located south of .

Stall Warning
In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack increases.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', p. 486. Aviation Supplies & Academics, 1997. This occurs when the critical angle of attack of the foil is exceeded. The critical angle of attack is typically about 15°, but it may vary significantly depending on the fluid, foil, and Reynolds number. Stalls in fixed-wing flight are often experienced as a sudden reduction in lift as the pilot increases the wing's angle of attack and exceeds its critical angle of attack (which may be due to slowing down below stall speed in level flight). A stall does not mean that the engine(s) have stopped working, or that the aircraft has stopped moving—the effect is the same even in an unpowered glider aircraft. Vectored thrust in aircraft is used to maintain altitude or controlled flight with wings stalled by replacing lost wing lift with engine or propeller ...

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 as a "black box", an outdated name which has become a misnomer—they are now required to be painted 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 International Civil Aviation Organizat ...

Farah, Afghanistan
Farah (Pashto/Dari: ) is the capital and largest city of Farah Province in western Afghanistan. It is located on the Farah River, close to the border with Iran. It is one of the largest cities of western Afghanistan in terms of population, with about 1.5 million people living in its urban area. Land use Farah is located in western Afghanistan between Kandahar and Herat, close to the border with Iran, although it lacks a direct road connection with the latter. Farah has a very clear grid of roads distributed through the higher-density residential areas. However barren land (35%) and vacant plots (25%) are the largest land uses and combine for 60% of total land use. History Ancient history The Citadel at Farah is probably one of a series of fortresses constructed by Alexander the Great, the city being an intermediate stop between Alexandria Arachosia (modern Kandahar) and Herat, the location of another of Alexander's fortresses. The "Alexandria" prefix was added to the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Army
The United States Army (USA) is the land service branch of the United States Armed Forces. It is one of the eight U.S. uniformed services, and is designated as the Army of the United States in the U.S. Constitution.Article II, section 2, clause 1 of the United States Constitution (1789). See alsTitle 10, Subtitle B, Chapter 301, Section 3001 The oldest and most senior branch of the U.S. military in order of precedence, the modern U.S. Army has its roots in the Continental Army, which was formed 14 June 1775 to fight the American Revolutionary War (1775–1783)—before the United States was established as a country. After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784 to replace the disbanded Continental Army.Library of CongressJournals of the Continental Congress, Volume 27/ref> The United States Army considers itself to be a continuation of the Continental Army, and thus considers its institutional inception to be th ...

First Officer (civil Aviation)
In aviation, the first officer (FO), also called co-pilot, is the pilot who is second-in-command of the aircraft to the captain, who is the legal commander. In the event of incapacitation of the captain, the first officer will assume command of the aircraft. Control of the aircraft is normally shared equally between the first officer and the captain, with one pilot normally designated the "pilot flying" and the other the "pilot not flying", or "pilot monitoring", for each flight. Even when the first officer is the flying pilot, however, the captain remains ultimately responsible for the aircraft, its passengers, and the crew. In typical day-to-day operations, the essential job tasks remain fairly equal. Traditionally, the first officer sits on the right-hand side of a fixed-wing aircraft ("right seat") and the left-hand side of a helicopter (the reason for this difference is related to, in many cases, the pilot flying being unable to release the right hand from the cyclic contr ...

Baghdad
Baghdad (; ar, بَغْدَاد , ) is the capital of Iraq and the second-largest city in the Arab world after Cairo. It is located on the Tigris near the ruins of the ancient city of Babylon and the Sassanid Persian capital of Ctesiphon. In 762 CE, Baghdad was chosen as the capital of the Abbasid Caliphate, and became its most notable major development project. Within a short time, the city evolved into a significant cultural, commercial, and intellectual center of the Muslim world. This, in addition to housing several key academic institutions, including the House of Wisdom, as well as a multiethnic and multi-religious environment, garnered it a worldwide reputation as the "Center of Learning". Baghdad was the largest city in the world for much of the Abbasid era during the Islamic Golden Age, peaking at a population of more than a million. The city was largely destroyed at the hands of the Mongol Empire in 1258, resulting in a decline that would linger through many c ...

Green Zone
The Green Zone ( ar, المنطقة الخضراء, translit=al-minṭaqah al-ḫaḍrā) is the most common name for the International Zone of Baghdad. It was a area in the Karkh district of central Baghdad, Iraq, that was the governmental center of the Coalition Provisional Authority during the occupation of Iraq after the American-led 2003 invasion and remains the center of the international presence in the city. Its official name beginning under the Iraqi Interim Government was the ''International Zone'', though ''Green Zone'' remains the most commonly used term. The contrasting Red Zone refers to parts of Baghdad immediately outside the perimeter, but was also loosely applied to all unsecured areas outside the ''off-site'' military posts. Both terms originated as military designations. History The Green Zone was a heavily fortified zone in the center of the Iraqi capital that served as the headquarters of successive Iraqi regimes. It was the administrative center fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
