American Airlines Flight 723
American Airlines Flight 723 was a scheduled American Airlines flight from Boston Airport in Massachusetts, to Chicago Midway Airport in Illinois. On September 16, 1953, a Convair 240 propliner flying this route crashed while attempting to land at Albany Airport in upstate New York (state), New York, killing all 28 people on board. Accident The Convair had arrived at Bradley International Airport, Bradley Field from Boston Airport at 6:57 am for a scheduled stopover. At that time, weather at Albany was below airline landing minima, but was forecast to improve within limits by the flight's scheduled arrival time. The flight left Bradley at 7:14, and once in the Albany terminal area, found poor visibility preventing landings, with several aircraft ahead of it in a holding pattern. The flight joined the holding pattern, circling while awaiting weather conditions legal for landing. At 7:50, a special weather observation reported thin obscurement, with an overcast ceiling (cloud), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, under aircraft pilot, pilot control, is unintentionally flown into the ground, a mountain, a body of water or an obstacle. In a typical CFIT scenario, the aircrew, crew is unaware of the impending disaster until it is too late. 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 not considered CFIT (they are known as ''uncontrolled flight into terrain'' or ''UFIT''), nor are incidents resulting from the deliberate action of the person at the controls, such as acts of terrorism or suicide by pilot. 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 aircraft. CFIT was identified as a cause of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceiling (cloud)
In aviation, ceiling is a measurement of the height of the base of the lowest clouds (not to be confused with cloud base which has a specific definition) that cover more than half of the sky (more than 4 oktas) relative to the ground. Ceiling is not specifically reported as part of the METAR (METeorological Aviation Report) used for flight planning by pilots worldwide, but can be deduced from the lowest height with broken (BKN) or overcast (OVC) reported. A ceiling listed as "unlimited" means either that the sky is mostly free of cloud cover, or that the cloud is high enough not to impede Visual Flight Rules ( VFR) operation. Definitions ; ICAO : The height above the ground or water of the base of the lowest layer of cloud below 6000 meters (20,000 feet) covering more than half the sky. ; United Kingdom : The vertical distance from the elevation of an aerodrome to the lowest part of any cloud visible from the aerodrome which is sufficient to obscure more than half of the sky ...

Civil Aeronautics Board
The Civil Aeronautics Board (CAB) was an agency of the federal government of the United States, formed in 1938 and abolished in 1985, that regulated aviation services including scheduled passenger airline serviceStringer, David H."Non-Skeds: The Story of America’s Supplemental Airlines, Part 1: Industry in the United States,"'' AAHS Journal'', vol. 64, no.4 (Winter 2019) journal of the American Aviation Historical Society, excerpt online, retrieved April 8, 2020 and provided air accident investigation. The agency headquarters were in Washington, D.C. Functions The primary role of the CAB was to regulate scheduled commercial airline operations in the United States. The CAB strictly controlled all U.S. certificated airlines ("scheduled carriers") -- deciding which routes would be serviced by which airlines, and setting minimum limits on passenger fares (comparable to the Interstate Commerce Commission) -- effectively managing competition between airlines, and ensuring certain l ...

Flight Attendant
A flight attendant, also known as steward/stewardess or air host/air hostess, is a member of the aircrew aboard commercial flights, many business jets and some government aircraft. Collectively called cabin crew, flight attendants are primarily responsible for passenger safety and comfort. History The role of a flight attendant derives from that of similar positions on passenger ships or passenger trains, but it has more direct involvement with passengers because of the confined quarters on aircraft. Additionally, the job of a flight attendant revolves around safety to a much greater extent than those of similar staff on other forms of transportation. Flight attendants on board a flight collectively form a ''cabin crew'', as distinguished from pilots and engineers in the cockpit. The German Heinrich Kubis was the world's first flight attendant, in 1912. Kubis first attended the passengers on board the DELAG Zeppelin LZ 10 ''Schwaben''. He also attended to the famous ...

Schenectady
Schenectady () is a city in Schenectady County, New York, United States, of which it is the county seat. As of the 2020 census, the city's population of 67,047 made it the state's ninth-largest city by population. The city is in eastern New York, near the confluence of the Mohawk and Hudson rivers. It is in the same metropolitan area as the state capital, Albany, which is about southeast. Schenectady was founded on the south side of the Mohawk River by Dutch colonists in the 17th century, many of whom came from the Albany area. The name "Schenectady" is derived from the Mohawk word ''skahnéhtati'', meaning "beyond the pines" and used for the area around Albany, New York. Residents of the new village developed farms on strip plots along the river. Connected to the west by the Mohawk River and Erie Canal, Schenectady developed rapidly in the 19th century as part of the Mohawk Valley trade, manufacturing, and transportation corridor. By 1824, more people worked in manufacturi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trailer Park
A trailer park,caravan park, mobile home park, mobile home community or manufactured home community is a temporary or permanent area for mobile homes and travel trailers. Advantages include low cost compared to other housing, and quick and easy moving to a new area (for example, when taking a job in a distant place while keeping the same home). Trailer parks, especially in American culture, are stereotypically viewed as lower income housing for occupants living at or below the poverty line who have low social status. Despite the advances in trailer home technology, the trailer park image survives as evoked by a statement from Presidential adviser James Carville who, in the course of one of the Bill Clinton White House political scandals, suggested "Drag $100 bills through trailer parks, there's no telling what you'll find," in reference to Paula Jones. Tornadoes and hurricanes often inflict serious damage on trailer parks, usually because the structures are not secured to the ...

Aileron
An aileron (French for "little wing" or "fin") is a hinged flight control surface usually forming part of the trailing edge of each wing of a fixed-wing aircraft. Ailerons are used in pairs to control the aircraft in roll (or movement around the aircraft's longitudinal axis), which normally results in a change in flight path due to the tilting of the lift vector. Movement around this axis is called 'rolling' or 'banking'. Considerable controversy exists over credit for the invention of the aileron. The Wright brothers and Glenn Curtiss fought a years-long legal battle over the Wright patent of 1906, which described a method of wing-warping to achieve lateral control. The brothers prevailed in several court decisions which found that Curtiss's use of ailerons violated the Wright patent. Ultimately, the First World War compelled the U.S. Government to legislate a legal resolution. A much earlier aileron concept was patented in 1868 by British scientist Matthew Piers Watt Bou ...

Final Approach (aviation)
In aeronautics, the final approach (also called the final leg and final approach leg) is the last leg in an aircraft's approach to landing, when the aircraft is lined up with the runway and descending for landing.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 213 and 241. Aviation Supplies & Academics, 1997. In aviation radio terminology, it is often shortened to "final". In a standard airport landing pattern, which is usually used under visual meteorological conditions (VMC), aircraft turn from base leg to final within one-half to two miles of the airport. For instrument approaches, as well as approaches into a controlled airfield under visual flight rules (VFR), often a "straight-in" final approach is used, where all the other legs are dispensed with. Straight-in approaches are discouraged at non-towered airports in the United States. Approach slope An approach slope is the path that an airplane follows on its final approach to land on a runway.

Contact Approach
A contact approach is an approach available to aircraft operating on an instrument flight rules (IFR) flight plan, where the pilot may deviate from the published instrument approach procedure (IAP) and proceed to the destination airport by visual reference to the surface. It is similar to a visual approach, except that the pilot is not required to have the destination airport nor the preceding aircraft in sight at all times during the approach, and the visibility requirements are less stringent. Overview Only pilots may initiate a request for this type of approach; regulations prohibit air traffic control (ATC) from asking pilots to perform them. A contact approach will only be issued if the aircraft is operating clear of clouds with at least 1 statute mile (1.6 km) of flight visibility, with a reasonable expectation of continuing to the destination airport under those conditions. Additionally, the reported ground visibility at the destination airport must be at least 1 statute mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Control Tower
Air traffic control (ATC) is a service provided by ground-based air traffic controllers who direct aircraft on the ground and through a given section of controlled airspace, and can provide advisory services to aircraft in non-controlled airspace. The primary purpose of ATC worldwide is to prevent collisions, organize and expedite the flow of air traffic, and provide information and other support for pilots. Air traffic controllers monitor the location of aircraft in their assigned airspace by radar and communicate with the pilots by radio. To prevent collisions, ATC enforces Separation (air traffic control), traffic separation rules, which ensure each aircraft maintains a minimum amount of empty space around it at all times. In many countries, ATC provides services to all private, military, and commercial aircraft operating within its airspace. Depending on the type of flight and the class of airspace, ATC may issue ''instructions'' that pilots are required to obey, or ''advis ...
