Colgan Flight 3407
Colgan Air Flight 3407 was a scheduled passenger flight from Newark, New Jersey, to Buffalo, New York, on February 12, 2009. Approaching Buffalo, the aircraft, a Bombardier Q400, entered an aerodynamic stall from which it did not recover and crashed into a house at 6038 Long Street in Clarence Center, New York, at 10:17 pm EST (03:17 UTC), about from the end of the runway, killing all 49 passengers and crew on board and one person inside the house. Note: The predicted stall speed for this aircraft at a flight load of 1.42 Gs would be about 125 kt, which is arrived at by multiplying 105 kt (the predicted stall speed at 1 G) by 1.19164 (the square root of the flight load in Gs). The National Transportation Safety Board conducted the accident investigation and published a final report on February 2, 2010, that identified the probable cause as the pilots' inappropriate response to stall warnings. Colgan Air staffed and maintained the aircraft used on the flight that was s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stall (fluid Dynamics)
In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack exceeds its critical value.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', p. 486. Aviation Supplies & Academics, 1997. The critical angle of attack is typically about 15°, but it may vary significantly depending on the fluid, foil – including its shape, size, and finish – and Reynolds number. Stalls in fixed-wing aircraft are often experienced as a sudden reduction in lift. It may be caused either by the pilot increasing the wing's angle of attack or by a decrease in the critical angle of attack. The former may be due to slowing down (below stall speed), the latter by accretion of ice on the wings (especially if the ice is rough). 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 al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regional Airline
A regional airline is a general classification of airline which typically operates scheduled passenger air service, using regional aircraft, between communities lacking sufficient demand or infrastructure to attract mainline flights. In North America, most regional airlines are classified as "fee-for-departure" carriers, operating their revenue flights as codeshare services contracted by one or more major airline partners. A number of regional airlines, particularly during the 1960s and 1970s, were classified as commuter airlines in the Official Airline Guide (OAG). History Background Decades before the advent of jet airliners and high-speed, long-range air service, commercial aviation was structured similarly to rail transport networks. In this era, technological limitations on air navigation and propeller-driven aircraft performance imposed strict constraints on the potential length of each flight; some routes covered less than . As such, airlines structured their s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colgan Air Flight 9446
Colgan Air Flight 9446 was a repositioning flight operated by Colgan Air for US Airways Express. On August 26, 2003, the Beechcraft 1900D crashed into water offshore from Yarmouth, Massachusetts, shortly after taking off from Barnstable Municipal Airport in Hyannis. Both pilots were killed. Aircraft and crew Flight 9446 was an unscheduled deadhead flight of a Beechcraft 1900D ( registration '). The aircraft had just finished receiving maintenance and was being repositioned to Albany, New York to return to revenue service. The two occupants of the plane were its pilots, Captain Scott Knabe (39) and First Officer Steven Dean (38). Captain Knabe had been with Colgan Air for two years and had 2,891 flight hours, including 1,364 hours on the Beechcraft 1900. Dean had been with the airline for less than a year and had 2,489 flight hours, 689 of which were on the Beechcraft 1900.

Airline Codes
This is a list of airline codes. The table lists IATA's two-character airline designators, ICAO's three-character airline designators and the airline call signs (telephony designator). IATA airline designator IATA airline designators, sometimes called IATA reservation codes, are two-character codes assigned by the International Air Transport Association (IATA) to the world's airlines. The standard is described in IATA's '' Standard Schedules Information Manual'' and the codes themselves are described in IATA's ''Airline Coding Directory''. (Both are published semiannually.) The IATA codes were originally based on the ICAO designators which were issued in 1947 as two-letter airline identification codes (see the section below). IATA expanded the two-character-system with codes consisting of a letter and a digit (or vice versa) e.g. EasyJet's U2 after ICAO had introduced its current three-letter-system in 1982. Until then, only combinations of letters were used. Airline desig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flight Attendant
A flight attendant is a member of the aircrew whose primary responsibility is ensure the safety of passengers in the cabin of an aircraft across all stages of flight. Their secondary duty is to see to the comfort of passengers. Flight attendants are also known as a steward () or stewardess (), or air host () or air hostess () and are collectively referred to as cabin crew. History The role of a flight attendant derives from that of similar positions on passenger ships or Passenger railroad car, passenger trains, but 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 Aircraft pilot, pilots and Flight engineer, engineers in the cockpit. The German Heinrich Kubis was the world's first flight a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KATU
KATU (channel 2) is a television station in Portland, Oregon, United States, affiliated with ABC. It is owned by Sinclair Broadcast Group alongside La Grande–licensed independent station KUNP, channel 16 (which KATU simulcasts on its second digital subchannel). The two stations share studios on Northeast Sandy Boulevard in Portland; KATU's transmitter is located in the Sylvan-Highlands section of the city. KATU went on the air as the fourth commercial station in Portland in 1962. It was built and signed on by Fisher Broadcasting Company, later Fisher Communications, and originally served as an independent station before joining ABC in 1964.

First Officer (civil Aviation)
In aviation, the first officer (FO), also called co-pilot, is a pilot in addition 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. Requirement Historically, large aircraft had several personnel on the flight deck, such as a navigator, a flight engineer, and a dedicated radio operator. Improvements in automation and reliability have reduced this to two. Many aircraft require a minimum of two flight crew. The minimum crew requirement will be stated in the aircraft manuals by the manufacturer. In the European Union, all turbo-propeller aeroplanes with a maximum approved passenger seating configuration of more than nine and all turbo-jet aeroplanes require two pilots.EU OPS (965) Subpart N, Ops 1.940 Composition of flight crew Role Control of the aircraft is normally shared equally between the first officer and the captain, with one pilot normally designated the " pilot flying" an ...

Maple Valley, Washington
Maple Valley is a city in King County, Washington United States. The population was 28,013 at the 2020 census. The city functions as a commuter town for residents, though there is an increasing amount of commercial activity in the area. History The area was settled in 1879 by three men who were improving a trail and brought their families in. When a name for a future community was proposed, the names Vine Maple Valley and Maple Ridge were suggested. A vote was taken by writing the names on slips of paper and placing them in a hat. Vine Maple Valley won by 2/3, but the word "Vine" was later cut by the post office because it made the name too long. The town's early history mainly had to do with coal, lumber milling to build homes, and a railroad that ran through town. Coal was brought in from Black Diamond to the south, but the town itself also mined coal from Cedar Mountain. The mine was used as late as 1947. Rail workers for lines like the Northern Pacific Railroad and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lutz, Florida
Lutz is an Unincorporated area#United States, unincorporated community in Hillsborough County, Florida, Hillsborough County and Pasco County, Florida, Pasco County, Florida, United States, north of Tampa. While there is a Census-designated place, census-designated area of Lutz, the community itself extends beyond those boundaries into other census-designated areas. History Lutz began with the construction of a small train depot on the Tampa Northern Railroad. The area surrounding the depot officially became known as "Lutz" when the U.S. Postal Service authorized a post office. The community was named for W. P. Lutz, who was credited with bringing the railroad to town. As people moved to the rural community from Tampa, Florida, Tampa, the Lutz area continued to grow until it no longer depended on the "Lutz Junction", which was demolished in the late 1960s. In 2000, a replica of the Train depot, depot was rebuilt in the approximate location, which is now at the intersection of L ...

Pilot In Command
The pilot in command (PIC) of an aircraft is the person aboard an aircraft who is ultimately responsible for its operation and safety during flight. This would be the captain in a typical two- or three- pilot aircrew, or "pilot" if there is only one certificated and qualified pilot at the controls of an aircraft. The PIC must be legally certificated (or otherwise authorized) to operate the aircraft for the specific flight and flight conditions, but need not be actually manipulating the controls at any given moment. The PIC is the person legally in charge of the aircraft and its flight safety and operation, and would normally be the primary person liable for an infraction of any flight rule. The strict legal definition of PIC may vary slightly from country to country. The International Civil Aviation Organization (ICAO) definition is: "The pilot responsible for the operation and safety of the aircraft during flight time." In Annex 2, "Rules of the Air", under par. "2.3.1 Responsi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
