Pilot Error
In aviation, pilot error generally refers to an action or decision made by a Aircraft pilot#Airline, pilot that is a substantial contributing factor leading to an Aviation accidents and incidents, aviation accident. It also includes a pilot's failure to make a correct decision or take proper action. Errors are intentional actions that fail to achieve their intended outcomes. The Chicago Convention on International Civil Aviation, Chicago Convention defines the term "accident" as "an occurrence associated with the operation of an aircraft [...] in which [...] a person is fatally or seriously injured [...] ''except when the injuries are [...] inflicted by other persons."'' Hence the definition of "pilot error" does not include deliberate crashing (and such crashes are not classified as accidents). The causes of pilot error include psychological and physiological human limitations. Various forms of threat and error management have been implemented into pilot training programs ...

Instrument Meteorological Conditions
In aviation, instrument meteorological conditions (IMC) are weather conditions that require pilots to fly primarily by reference to flight instruments, and therefore under instrument flight rules (IFR), as opposed to flying by outside visual references under visual flight rules (VFR). Typically, this means flying in cloud or poor weather, where little or nothing can be seen or recognised when looking out of the window. Simulated IMC can be achieved for training purposes by wearing view-limiting devices, which restrict outside vision and force the trainee to rely on instrument indications only. Distinction from Visual Meteorological Conditions The weather conditions required for flight under VFR are known as visual meteorological conditions (VMC). The boundary criteria between VMC and IMC are known as ''VMC minima''. IMC and VMC are mutually exclusive. In fact, instrument meteorological conditions are defined as less than the minima specified for visual meteorological conditions ...

Knik Glacier
The Knik Glacier ( Dena'ina: ''Skitnu Łi'a'') is an ice field located east of Anchorage, Alaska on the northern end of the Chugach Mountains. The ice field averages over long and over across, making it one of the largest glaciers in southcentral Alaska. Knik Glacier feeds the long Knik River which empties into the Knik Arm section of Cook Inlet. Lake George Lake George , a glacial lake formed near the face of the glacier, received national recognition by the National Natural Landmark (NNL) Program. Lake George was recognized because of a unique natural phenomenon called a "jökulhlaup", an Icelandic term for glacial lake outburst flood. The breakup of this ice dam would send a violent wall of water, ice and debris down the river valley causing massive flooding and sometimes devastation to local settlers' properties. The jökulhlaup occurred annually until it ceased in 1967 due to glacial recession, thought to be associated with the massive Good Friday earthquake of 1964. ...

Heliskiing
Heli-skiing is off-trail, downhill skiing or snowboarding where the skier reaches the top of the mountain by helicopter, instead of a ski lift. History In the late 1950s, helicopters were used in Alaska and Europe to access remote terrain. The idea of heliskiing first came from a Canadian geologist Art Patterson. Patterson used helicopters for his works during summer, however, he noticed that during winter time there was no use for the helicopters. Since he was a enthusiastic skier, he thought about using the helicopters to transport skiers to the top of the mountains. He teamed up with Hans Gmoser who was an experienced mountain guide and created a business together. They charged 20$ for their first day of heliskiing, however, due to unfavorable weather conditions and a small Bell 47G-2 helicopter, Patterson decided the business is too risky and withdrew from the venture. However, Gmoser continued in the business idea and in 1965 commercialized the activity in Canada by foundi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alaska Airbus AS350 B3 Helicopter Crash Site Overview
Alaska ( ) is a non-contiguous U.S. state on the northwest extremity of North America. Part of the Western United States region, it is one of the two non-contiguous U.S. states, alongside Hawaii. Alaska is also considered to be the northernmost, westernmost, and easternmost (the Aleutian Islands cross the 180th meridian into the eastern hemisphere) state in the United States. It borders the Canadian territory of Yukon and the province of British Columbia to the east. It shares a western maritime border, in the Bering Strait, with Russia's Chukotka Autonomous Okrug. The Chukchi and Beaufort Seas of the Arctic Ocean lie to the north, and the Pacific Ocean lies to the south. Technically, it is a semi-exclave of the U.S., and is the largest exclave in the world. Alaska is the largest U.S. state by area, comprising more total area than the following three largest states of Texas, California, and Montana combined, and is the seventh-largest subnational division in the world. ...

AKDT
The Alaska Time Zone observes standard time by subtracting nine hours from Coordinated Universal Time ( UTC−09:00). During daylight saving time its time offset is eight hours ( UTC−08:00). The clock time in this zone is based on mean solar time at the 135th meridian west of the Greenwich Observatory. The zone includes nearly all of the U.S. state of Alaska and is one hour behind the Pacific Time Zone. *standard time: Alaska Standard Time (AKST) *daylight saving time: Alaska Daylight Time (AKDT) The western Aleutian Islands observe Hawaii–Aleutian Time, one hour behind the remainder of the state. The largest city in the Alaskan Time Zone is Anchorage, Alaska. The Anchorage Metropolitan Area is the largest metropolitan area in the zone. Effective from 2007, the local time changes from AKST to AKDT at 02:00 AKST to 03:00 AKDT on the second Sunday in March and returns at 02:00 AKDT to 01:00 AKST on the first Sunday in November.

Aviation Accidents And Incidents In The United States In 2021
Aviation includes the activities surrounding mechanical flight and the aircraft industry. ''Aircraft'' include fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air aircraft 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. Clément Ader built the "Ader Éole" in France and made an uncontrolled, powered hop in 1890. This was the first powered aircraft, although it did not achieve controlled flight. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896. A major leap followed with the construction of the ''Wright Flyer'', 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 engine which enabled aviation ...

Accidents And Incidents Involving Helicopters
An accident is an unintended, normally unwanted event that was not deliberately caused by humans. The term ''accident'' implies that the event may have been caused by unrecognized or unaddressed risks. Many researchers, insurers and attorneys who specialize in unintentional injury prefer to avoid using the term ''accident'', and focus on conditions that increase risk of severe injury or that reduce injury incidence and severity. For example, when a tree falls down during a wind storm, its fall may not have been directly caused by human error, but the tree's type, size, health, location, or improper maintenance may have contributed to the result. Most car crashes are the result of dangerous behavior and not purely ''accidents''; however, English speakers started using that word in the mid-20th century as a result of media manipulation by the US automobile industry. Accidental deaths were much less frequent before high-powered machinery began to spread with the Industrial Revolutio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
