Kegworth Air Disaster
The Kegworth air disaster occurred when British Midland Airways Flight 092, a Boeing 737-400, crashed onto the motorway embankment between the M1 motorway and A453 road near Kegworth, Leicestershire, England, while attempting to make an emergency landing at East Midlands Airport on 8 January 1989. The aircraft was on a scheduled flight from London Heathrow Airport to Belfast International Airport when a fan blade broke in the left engine, disrupting the air conditioning and filling the cabin with smoke. The pilots believed this indicated a fault in the right engine, since earlier models of the 737 ventilated the cabin from the right, and they were unaware that the 737-400 used a different system. The pilots mistakenly shut down the functioning engine. They selected full thrust from the malfunctioning one and this increased its fuel supply, causing it to catch fire. Of the 126 people aboard, 47 died and 74 sustained serious injuries. The inquiry attributed the blade fracture ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Midlands Airport
East Midlands Airport is an international airport in the East Midlands of England, close to Castle Donington in northwestern Leicestershire, between Loughborough (), Derby () and Nottingham (); Leicester is () to the south and Lincoln () northeast. It serves the whole East Midlands region of Leicestershire, Nottinghamshire, Lincolnshire, Northamptonshire, Rutland and Derbyshire. The airfield was originally built as a Royal Air Force station known as RAF Castle Donington in 1943, before being redeveloped as a civilian airport in 1965. East Midlands Airport has established itself as a hub for low-fare airlines such as Jet2.com and Ryanair and tour operators like TUI Airways, which serve a range of domestic and European short-haul destinations. Passenger numbers peaked in 2008 at 5.6 million but declined to around 4.5 million in 2015, making it the 11th-busiest airport in the UK by passenger traffic. A central air cargo hub, it was the second-busiest UK airport for fre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BBC Online
BBC Online, formerly known as BBCi, is the BBC's online service. It is a large network of websites including such high-profile sites as BBC News and BBC Sport, Sport, the on-demand video and radio services branded BBC iPlayer and BBC Sounds, the children's sites CBBC (TV channel), CBBC and CBeebies, and learning services such as Bitesize and BBC Own It, Own It. The BBC has had an online presence supporting its TV and radio programmes and web-only initiatives since April 1994, but did not launch officially until 28 April 1997, following government approval to fund it by Television licensing in the United Kingdom, TV licence fee revenue as a service in its own right. Throughout its history, the online plans of the BBC have been subject to competition and complaint from its commercial rivals, which has resulted in various public consultations and government reviews to investigate their claims that its large presence and public funding distorts the UK market.

Bleed Air
Bleed air is compressed air taken from the compressor stage of a gas turbine upstream of its fuel-burning sections. Automatic air supply and cabin pressure controller (ASCPCs) valves bleed air from high or low stage engine compressor sections. Low stage air is used during high power setting operation, and high during descent and other low power setting operations. Bleed air from that system can be utilized for internal cooling of the engine, cross-starting another engine, engine and airframe anti-icing, cabin pressurization, pneumatic actuators, air-driven motors, pressurizing the hydraulic reservoir, and waste and water storage tanks. Some engine maintenance manuals refer to such systems as "customer bleed air". Bleed air is valuable in an aircraft for two properties: high temperature and high pressure (typical values are 200–250 °C and 275 kPa (40 PSI), for regulated bleed air exiting the engine pylon for use throughout the aircraft). Uses In civil aircraft, bleed a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Special Air Service
The Special Air Service (SAS) is a special forces unit of the British Army. It was founded as a regiment in 1941 by David Stirling and in 1950, it was reconstituted as a corps. The unit specialises in a number of roles including counter-terrorism, hostage rescue, direct action and covert reconnaissance. Much of the information about the SAS is highly classified, and the unit is not commented on by either the British government or the Ministry of Defence due to the secrecy and sensitivity of its operations. The corps currently consists of the 22 Special Air Service Regiment, the regular component, as well as the 21 Special Air Service Regiment (Artists) (Reserve) and the 23 Special Air Service Regiment (Reserve), which are reserve units, all under the operational command of United Kingdom Special Forces (UKSF). Its sister unit is the Royal Navy's Special Boat Service which specialises in maritime counter-terrorism. Both units are under the operational control of the Dire ...

Troop
A troop is a military sub-subunit, originally a small formation of cavalry, subordinate to a squadron. In many armies a troop is the equivalent element to the infantry section or platoon. Exceptions are the US Cavalry and the King's Troop Royal Horse Artillery where a troop is a subunit comparable to an infantry company or artillery battery. Historically the remainder of the Royal Horse Artillery used the term Troop in the same manner however they are now aligned with the rest of the Royal Regiment of Artillery in referring to Troops as subordinate to artillery batteries. Troops is often used to refer to the other members of one's company or cause, but because of its military connotations, it conveys a particularly altruistic type of dedicated worker. Traditionally, troops refers to the soldiers in a military. A cavalry soldier of private rank is called a trooper in many Commonwealth armies (abbreviated "Tpr", not to be confused with "trouper").

Posttraumatic Stress Disorder
Post-traumatic stress disorder (PTSD) is a mental and behavioral disorder that can develop because of exposure to a traumatic event, such as sexual assault, warfare, traffic collisions, child abuse, domestic violence, or other threats on a person's life. Symptoms may include disturbing thoughts, feelings, or dreams related to the events, mental or physical distress to trauma-related cues, attempts to avoid trauma-related cues, alterations in the way a person thinks and feels, and an increase in the fight-or-flight response. These symptoms last for more than a month after the event. Young children are less likely to show distress but instead may express their memories through play. A person with PTSD is at a higher risk of suicide and intentional self-harm. Most people who experience traumatic events do not develop PTSD. People who experience interpersonal violence such as rape, other sexual assaults, being kidnapped, stalking, physical abuse by an intimate partner ...

Royal Marine
The Corps of Royal Marines (RM), also known as the Royal Marines Commandos, are the UK's special operations capable commando force, amphibious light infantry and also one of the five fighting arms of the Royal Navy. The Corps of Royal Marines can trace their origins back to the formation of the "Duke of York and Albany's maritime regiment of Foot" on 28 October 1664, and can trace their commando origins to the formation of the 3rd Special Service Brigade, now known as 3 Commando Brigade on 14 February 1942, during the Second World War. As a specialised and adaptable light infantry and commando force, Royal Marine Commandos are trained for rapid deployment worldwide and capable of dealing with a wide range of threats. The Corps of Royal Marines is organised into 3 Commando Brigade and a number of separate units, including 47 Commando (Raiding Group) Royal Marines, and a company-strength commitment to the Special Forces Support Group. The Corps operates in all environments an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stick Shaker
A stick shaker is a mechanical device designed to rapidly and noisily vibrate the control yoke (the "stick") of an aircraft, warning the flight crew that an imminent aerodynamic stall has been detected. It is typically present on the majority of large civil jet aircraft, as well as most large military planes. The stick shaker comprises a key component of an aircraft's stall protection system. Several accidents, such as the 1963 BAC One-Eleven test crash and American Airlines Flight 191, were attributable to aerodynamic stalls and motivated aviation regulatory bodies to establish requirements for certain aircraft to be outfitted with stall protection measures, such as the stick shaker and stick pusher, to reduce such occurrences. While the stick shaker has become relatively prevalent amongst airliners and large transport aircraft, such devices are not infallible and require flight crews to be appropriately trained on their functionality and how to respond to their activation.

Flameout
In aviation, a flameout (or flame-out) is the run-down of a jet engine or other turbine engine due to the extinction of the flame in its combustor. The loss of flame can have a variety of causes, such as fuel starvation, excessive altitude, compressor stall, foreign object damage deriving from birds, hail, or volcanic ash, severe precipitation, mechanical failure, or very low ambient temperatures. Engine control Early jet engines were prone to flameout following disturbances of inlet airflow, or sudden or inappropriate thrust lever movements, which resulted in incorrect air-fuel ratios in the combustion chamber. Modern engines are much more robust in this respect, and are often digitally controlled, which allows for a significantly more effective control of all engine parameters to prevent flameouts and even initiate an automatic restart if a flameout occurs. Flameouts occur most frequently at intermediate or low power settings such as in cruise and descent. To prevent a fla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Autothrottle
An autothrottle (automatic throttle, also known as autothrust, A/T) 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' work load 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. This mode controls aircraft speed within safe operating margins. For example, if the pilot selects a target speed which is slower than stall speed, or a speed faster than maximum speed, the autothrottle system will ...
