MD-10
The McDonnell Douglas DC-10 is an American trijet wide-body aircraft manufactured by McDonnell Douglas. The DC-10 was intended to succeed the DC-8 for long-range flights. It first flew on August 29, 1970; it was introduced on August 5, 1971, by American Airlines. The trijet has two turbofans on underwing pylons and a third one at the base of the vertical stabilizer. The twin-aisle layout has a typical seating for 270 in two classes. The initial DC-10-10 had a range for transcontinental flights. The DC-10-15 had more powerful engines for hot and high airports. The DC-10-30 and −40 models (with a third main landing gear leg to support higher weights) each had intercontinental ranges of up to . The KC-10 Extender (based on the DC-10-30) is a U.S. Air Force tanker. A design flaw in the original cargo doors caused a poor safety record in early operations.

American Airlines Flight 191
American Airlines Flight 191 was a regularly scheduled domestic passenger flight in the United States operated by American Airlines from Chicago O'Hare International Airport to Los Angeles International Airport. On the afternoon of May 25, 1979, the McDonnell Douglas DC-10-10 operating this flight was taking off from runway 32R when its left engine detached, causing loss of control, and it crashed less than from the end of the runway. All 258 passengers and 13 crew on board were killed, along with two people on the ground. With 273 fatalities, it is the deadliest aviation accident to have occurred in the United States. The National Transportation Safety Board (NTSB) found that as the aircraft was beginning its takeoff rotation, engine number one (the left engine) separated from the left wing, flipping over the top of the wing and landing on the runway. As the engine separated from the aircraft, it severed hydraulic fluid lines that lock the wing's leading-edge slats in pla ...

Hot And High
In aviation, hot and high is a condition of low air density due to high ambient temperature and high airport elevation. Air density decreases with increasing temperature and altitude. The lower air density reduces the power output from the aircraft's engine and also requires a higher true airspeed before the aircraft can become airborne. Aviators gauge air density by calculating the density altitude. An airport may be especially hot ''or'' high, without the other condition being present. Temperature and pressure altitude can change from one hour to the next. The fact that temperature decreases as altitude increases mitigates the "hot and high" effect to a small extent. Negative effects of reduced engine power due to hot and high conditions * Airplanes require a longer takeoff run, potentially exceeding the amount of available runway. * Reduced take-off power hampers an aircraft's ability to climb. In some cases, an aircraft may be unable to climb rapidly enough to clear terrain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KC-10 Extender
The McDonnell Douglas KC-10 Extender is an American aerial refueling tanker aircraft operated by the United States Air Force (USAF). A military version of the three-engine DC-10 airliner, the KC-10 was developed from the Advanced Tanker Cargo Aircraft Program. It incorporates military-specific equipment for its primary roles of transport and aerial refueling. It was developed to supplement the KC-135 Stratotanker following experiences in Southeast Asia and the Middle East. The KC-10 was the second McDonnell Douglas transport aircraft to be selected by the Air Force following the C-9. A total of 60 KC-10s were produced for the USAF. The Royal Netherlands Air Force operated two similar tankers designated ''KDC-10'' that were converted from DC-10s. The KC-10 plays a key role in the mobilization of US military assets, taking part in overseas operations far from home. These aircraft performed airlift and aerial refueling during the 1986 bombing of Libya (Operation Eldorado Canyon), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Design Flaw
A product defect is any characteristic of a product which hinders its usability for the purpose for which it was designed and manufactured. Product defects arise most prominently in legal contexts regarding product safety, where the term is applied to "anything that renders the product not reasonably safe".Patricia A. Robinson, ''Writing and Designing Manuals and Warnings'' (2009), p. 234. The field of law that addresses injuries caused by defective products is called ''product liability''. A wide range of circumstances can render a product defective. The product may have a design defect or design flaw, resulting from the product having been poorly designed or tested, so that the design itself yields a product that can not perform its desired function. Even if the design is correct, the product may have a manufacturing defect if it was incorrectly manufactured, for example if the wrong materials are used. A product may also be considered legally defective if it lacks appropriate i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Door
A door is a hinged or otherwise movable barrier that allows ingress (entry) into and egress (exit) from an enclosure. The created opening in the wall is a ''doorway'' or ''portal''. A door's essential and primary purpose is to provide security by controlling access to the doorway (portal). Conventionally, it is a panel that fits into the doorway of a building, room, or vehicle. Doors are generally made of a material suited to the door's task. They are commonly attached by hinges, but can move by other means, such as slides or counterbalancing. The door may be able to move in various ways (at angles away from the doorway/portal, by sliding on a plane parallel to the frame, by folding in angles on a parallel plane, or by spinning along an axis at the center of the frame) to allow or prevent ingress or egress. In most cases, a door's interior matches its exterior side. But in other cases (e.g., a vehicle door) the two sides are radically different. Many doors incorporate locking ...

Aviation Safety
Aviation safety is the study and practice of managing risks in aviation. This includes preventing aviation accidents and incidents through research, educating air travel personnel, passengers and the general public, as well as the design of aircraft and aviation infrastructure. The aviation industry is subject to significant regulation and oversight. Aviation security is focused on protecting air travelers, aircraft and infrastructure from intentional harm or disruption, rather than unintentional mishaps. Statistics Evolution In 1926 and 1927, there were a total of 24 fatal commercial airline crashes, a further 16 in 1928, and 51 in 1929 (killing 61 people), which remains the worst year on record at an accident rate of about 1 for every flown. Based on the current numbers flying, this would equate to 7,000 fatal incidents per year. For the ten-year period 2002 to 2011, 0.6 fatal accidents happened per one million flights globally, 0.4 per million hours flown, 22.0 fatal ...
