1974 Air East Crash
Commonwealth Commuter Flight 317 was a scheduled commuter flight from Pittsburgh, Pennsylvania to Johnstown, Pennsylvania, operated by Air East. On January 6, 1974, while on approach to Johnstown–Cambria County Airport, the Beechcraft Model 99A operating the flight crashed short of the runway after it failed to maintain flying speed and made a premature descent below the safe approach slope for undetermined reasons. Of the 15 passengers and two crew members on board, 11 passengers and the aircraft captain were killed. Accident Flight 317 took off from Pittsburgh International Airport at about 6:30 p.m. on January 6, 1974 on a regularly scheduled commuter flight to Johnstown. There were 15 passengers aboard. The flight's captain, Daniel Brannon, 39, had accumulated 6,331 flight hours, including 383 hours in the Beechcraft 99A; the first officer, Gerald Knouff, 24, had accumulated 1790 flight hours, including 380 hours in the Beechcraft 99A.

Indicated Airspeed
Indicated airspeed (IAS) is the airspeed of an aircraft as measured by its pitot-static system and displayed by the airspeed indicator (ASI). This is the pilots' primary airspeed reference. This value is not corrected for installation error, instrument error, or the actual encountered air density, being instead calibrated to always reflect the adiabatic compressible flow of the International Standard Atmosphere at sea level. It uses the difference between total pressure and static pressure, provided by the system, to either mechanically or electronically measure dynamic pressure. The dynamic pressure includes terms for both density and airspeed. Since the airspeed indicator cannot know the density, it is by design calibrated to assume the sea level standard atmospheric density when calculating airspeed. Since the actual density will vary considerably from this assumed value as the aircraft changes altitude, IAS varies considerably from true airspeed (TAS), the relative velocity ...

Disasters In Pennsylvania
A disaster is a serious problem occurring over a short or long period of time that causes widespread human, material, economic or environmental loss which exceeds the ability of the affected community or society to cope using its own resources. Disasters are routinely divided into either "Natural disaster, natural disasters" caused by Natural hazard, natural hazards or "human-instigated disasters" caused from Anthropogenic hazard, anthropogenic hazards. However, in modern times, the divide between natural, human-made and human-accelerated disasters is difficult to draw. Examples of natural hazards include avalanche, avalanches, Flood, flooding, cold wave, cold waves and heat wave, heat waves, drought, droughts, earthquake, earthquakes, Cyclone, cyclones, landslide, landslides, lightning, tsunami, tsunamis, Volcanism, volcanic activity, wildfire, wildfires, and Winter storm, winter precipitation. Examples of anthropogenic hazards include Crime, criminality, civil disorder, terr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aviation Accidents And Incidents In The United States In 1974
Aviation includes the activities surrounding mechanical flight and the aircraft industry. ''Aircraft'' includes fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air craft such as hot air balloons and airships. Aviation began in the 18th century with the development of the hot air balloon, an apparatus capable of atmospheric displacement through buoyancy. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896; then a large step in significance came with the construction of the first powered airplane by the Wright brothers in the early 1900s. Since that time, aviation has been technologically revolutionized by the introduction of the jet which permitted a major form of transport throughout the world. Etymology The word ''aviation'' was coined by the French writer and former naval officer Gabriel La Landelle in 1863. He derived the term from the v ...

Airliner Accidents And Incidents In Pennsylvania
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 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 long-haul flights between airline hubs and major cities. A smaller, more common class of airliners is the 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- mainline counterparts to the larger aircraft operated by the major carri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pratt & Whitney Canada PT6
The Pratt & Whitney Canada PT6 is a turboprop aircraft engine produced by Pratt & Whitney Canada. Its design was started in 1958, it first ran in February 1960, first flew on 30 May 1961, entered service in 1964 and has been continuously updated since. It consists of two basic sections: a gas generator with accessory gearbox and a free power turbine with reduction gearbox, and is often seemingly mounted backwards in an aircraft in so far as the intake is at the rear and the exhaust at the front. Many variants of the PT6 have been produced, not only as turboprops but also as turboshaft engines for helicopters, land vehicles, hovercraft, and boats; as auxiliary power units; and for industrial uses. By November 2015, 51,000 had been produced, had logged 400 million flight hours from 1963 to 2016. It is known for its reliability with an in-flight shutdown rate of 1 per 651,126 hours in 2016. The PT6A covers the power range between while the PT6B/C are turboshaft variants for he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
