Mohawk Airlines Flight 411
Mohawk Airlines Flight 411, a Fairchild FH-227B twin-engine turboprop, registered N7811M, was a scheduled domestic passenger service operated by Mohawk Airlines, between Albany and Glens Falls, New York. On November 19, 1969, it crashed into Pilot Knob Mountain, killing all 14 passengers and crew on board. The National Transportation Safety Board (NTSB) concluded that the crash was caused by the captain's improper execution of an instrument approach, combined with a severe downdraft at a low altitude, which resulted in the aircraft descending uncontrollably into terrain. History of flight On the evening of November 19, 1969, at about 20:03 EST, Mohawk Airlines Flight 411, a twin engine Fairchild FH-227B turboprop, departed from Albany International Airport near Albany, New York. It was operating as a scheduled passenger/cargo flight on an instrument flight rules (IFR) flight plan to its destination of Warren County Airport in Glens Falls, New York, northeast, with an esti ...

Fairchild Hiller FH-227
The Fairchild F-27 and Fairchild Hiller FH-227 were versions of the Fokker F27 Friendship twin-engined turboprop passenger aircraft manufactured under license by Fairchild Hiller in the United States. The Fairchild F-27 was similar to the standard Fokker F27, while the FH-227 was an independently developed stretched version. Design and development The Fokker F27 began life as a 1950 design study known as the P275, a 32-seater powered by two Rolls-Royce Dart turboprops. With the aid of Dutch government funding, the P275 evolved into the F27, which first flew on November 24, 1955. The first prototype was powered by Dart 507s and would have seated 28. To correct a slight tail-heaviness and to allow for more seats, the second prototype (which first flew in January 1957) had a fuselage, which would allow seating for 32. By this stage, Fokker had signed an agreement that would see Fairchild build Friendships in the U.S. as the F-27. The first aircraft of either manufacturer to enter ...

Air Traffic Control
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 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 ''advisories'' (known as ''flight infor ...

Airliner Accidents And Incidents Caused By Pilot Error
An airliner is a type of aircraft for transporting passengers and air cargo. Such aircraft are most often operated by airlines. Although the definition of an airliner can vary from country to country, an airliner is typically defined as an airplane intended for carrying multiple passengers or cargo in commercial service. The largest of them are wide-body aircraft, wide-body jets which are also called twin-aisle because they generally have two separate aisles running from the front to the back of the passenger cabin. These are usually used for Flight length#long-haul, long-haul flights between airline hubs and major cities. A smaller, more common class of airliners is the narrow-body aircraft, narrow-body or single-aisle. These are generally used for short to medium-distance flights with fewer passengers than their wide-body counterparts. Regional airliners typically seat fewer than 100 passengers and may be powered by turbofans or turboprops. These airliners are the non-mainli ...

Accidents And Incidents Involving The Fairchild F-27
An accident is an unintended, normally unwanted event that was not directly caused by humans. The term ''accident'' implies that nobody should be blamed, but the event may have been caused by unrecognized or unaddressed risks. Most researchers who study unintentional injury avoid using the term ''accident'' and focus on factors that increase risk of severe injury and that reduce injury incidence and severity. For example, when a tree falls down during a wind storm, its fall may not have been caused by humans, but the tree's type, size, health, location, or improper maintenance may have contributed to the result. Most car wrecks are not true accidents; however English speakers started using that word in the mid-20th century as a result of media manipulation by the US automobile industry. Types Physical and non-physical Physical examples of accidents include unintended motor vehicle collisions, falls, being injured by touching something sharp or hot, or bumping into somet ...

Mohawk Airlines Flight 405
Mohawk Airlines Flight 405, a Fairchild Hiller FH-227 twin-engine turboprop airliner registered N7818M, was a domestic scheduled passenger flight operated by Mohawk Airlines that crashed into a house within the city limits of Albany, New York on March 3, 1972, on final approach to Albany County Airport (now Albany International Airport), New York, killing 17 people. The intended destination airport lies in the suburban Town of Colonie, about 4 miles north of the crash site. Flight history The flight, which originated in New York City, encountered problems during its final approach to runway 01 at Albany. The weather at the airport was reported to the flight crew as "ceiling indefinite, 1,200 feet obscured, 2 miles visibility in light snow, surface winds (from) 360 degrees (north) at 9 knots". As the Fairchild FH227B twin-engine turboprop reached 8.5 miles from the airport, the flight crew contacted Mohawk's operations center via radio and informed them that the left propeller wa ...

Lake George (lake), New York
Lake George ( moh, Kaniá:taro’kte), nicknamed the ''Queen of American Lakes'', is a long, narrow oligotrophic lake located at the southeast base of the Adirondack Mountains, in the northeastern portion of the U.S. state of New York. It lies within the upper region of the Great Appalachian Valley and drains all the way northward into Lake Champlain and the St. Lawrence River drainage basin. The lake is situated along the historical natural (Amerindian) path between the valleys of the Hudson and St. Lawrence Rivers, and so lies on the direct land route between Albany, New York, and Montreal, Quebec, Canada. The lake extends about on a north–south axis, is deep, and ranges from in width, presenting a significant barrier to east–west travel. Although the year-round population of the Lake George region is relatively small, the summertime population can swell to over 50,000 residents, many in the village of Lake George region at the southern end of the lake.

Tailwind
A tailwind is a wind that blows in the direction of travel of an object, while a headwind blows against the direction of travel. A tailwind increases the object's speed and reduces the time required to reach its destination, while a headwind has the opposite effect. The terms are also used metaphorically in business and elsewhere about circumstances where progress is made harder (headwind) or easier (tailwind). Travel In aeronautics, a headwind is favorable in takeoffs and landings because an airfoil moving into a headwind is capable of generating greater lift than the same airfoil moving through tranquil air, or with a tailwind, at equal ground speed. As a result, aviators and air traffic controllers commonly choose to take off or land in the direction of a runway that will provide a headwind. Aircraft carriers usually turn into the wind during takeoffs and landings, and may increase their own speed. While on take-off and landing, headwinds are good because they allow th ...

Distance Measuring Equipment
In aviation, distance measuring equipment (DME) is a radio navigation technology that measures the slant range (distance) between an aircraft and a ground station by timing the propagation delay of radio signals in the frequency band between 960 and 1215 megahertz (MHz). Line-of-visibility between the aircraft and ground station is required. An interrogator (airborne) initiates an exchange by transmitting a pulse pair, on an assigned 'channel', to the transponder ground station. The channel assignment specifies the carrier frequency and the spacing between the pulses. After a known delay, the transponder replies by transmitting a pulse pair on a frequency that is offset from the interrogation frequency by 63 MHz and having specified separation.''Annex 10 to the Convention on International Civil Aviation, Volume I – Radio Navigation Aids''; International Civil Aviation Organization; International Standards and Recommended Practices. DME systems are used worldwide, usi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Instrument Approach
In aviation, an instrument approach or instrument approach procedure (IAP) is a series of predetermined maneuvers for the orderly transfer of an aircraft operating under instrument flight rules from the beginning of the initial approach to a landing, or to a point from which a landing may be made visually. These approaches are approved in the European Union by EASA and the respective country authorities and in the United States by the FAA or the United States Department of Defense for the military. The ICAO defines an instrument approach as, "a series of predetermined maneuvers by reference to flight instruments with specific protection from obstacles from the initial approach fix, or where applicable, from the beginning of a defined arrival route to a point from which a landing can be completed and thereafter, if landing is not completed, to a position at which holding or enroute obstacle clearance criteria apply." There are three categories of instrument approach procedures: pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
