Japan Air System Flight 451
Japan Air System Flight 451 was a Japan Air System flight from Nagoya Airport in the Nagoya area of Aichi Prefecture, Japan to New Chitose Airport in Sapporo, Hokkaido Prefecture, with a stopover at Hanamaki Airport in Hanamaki, Iwate Prefecture. On April 18, 1993, the Douglas DC-9-41 operating the flight crashed while landing at Hanamaki Airport. The aircraft suddenly lost a significant amount of airspeed as it crossed the boundary line of a passing cold front, and encountered resultant windshear while on final approach. The somewhat inexperienced first officer was not able to conduct a missed approach fast enough to avoid a hard landing. The plane then skidded off the runway. All 72 passengers and five crew members survived, with 19 people sustaining injuries. The aircraft caught fire as the passengers evacuated; it was destroyed and written off.

Windshear
Wind shear (or windshear), sometimes referred to as wind gradient, is a difference in wind speed and/or direction over a relatively short distance in the atmosphere. Atmospheric wind shear is normally described as either vertical or horizontal wind shear. Vertical wind shear is a change in wind speed or direction with a change in altitude. Horizontal wind shear is a change in wind speed with a change in lateral position for a given altitude. Wind shear is a microscale meteorological phenomenon occurring over a very small distance, but it can be associated with mesoscale or synoptic scale weather features such as squall lines and cold fronts. It is commonly observed near microbursts and downbursts caused by thunderstorms, fronts, areas of locally higher low-level winds referred to as low-level jets, near mountains, radiation inversions that occur due to clear skies and calm winds, buildings, wind turbines, and sailboats. Wind shear has significant effects on the control of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Accidents And Incidents Involving The McDonnell Douglas DC-9
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 someth ...

Aviation Accidents And Incidents In Japan
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 ...

Aircraft Accident Investigation Commission
The Aircraft Accidents Investigation Commission (AAIC, 航空事故調査委員会 ''Kōkūjiko chōsa iinkai'') was a government agency of Japan which investigated aviation accidents and incidents. It was subordinate to the Ministry of Transport, and after January 2001 the Ministry of Land, Infrastructure, Transport and Tourism (MLIT). It was founded in 1974, following the All Nippon Airways Flight 58 Shizukuishi aircraft accident on July 30, 1971, and the Toa Domestic Airlines Flight 63 accident. On 1 October 2001 the agency was replaced by the Aircraft and Railway Accidents Investigation Commission (ARAIC).Yasuo Sat"Activities of Japan's Aircraft and Railway Accidents Investigation Commission" '' |
Chicago Sun-Times
The ''Chicago Sun-Times'' is a daily newspaper published in Chicago, Illinois, United States. Since 2022, it is the flagship paper of Chicago Public Media, and has the second largest circulation among Chicago newspapers, after the ''Chicago Tribune''. The modern paper grew out of the 1948 merger of the ''Chicago Sun'' and the ''Chicago Daily Times''. Journalists at the paper have received eight Pulitzer prizes, mostly in the 1970s; one recipient was film critic Roger Ebert (1975), who worked at the paper from 1967 until his death in 2013. Long owned by the Marshall Field family, since the 1980s ownership of the paper has changed hands numerous times, including twice in the late 2010s. History The ''Chicago Sun-Times'' claims to be the oldest continuously published daily newspaper in the city. That claim is based on the 1844 founding of the ''Chicago Daily Journal'', which was also the first newspaper to publish the rumor, now believed false, that a cow owned by Catherine O'L ...

Write-off
A write-off is a reduction of the recognized value of something. In accounting, this is a recognition of the reduced or zero value of an asset. In income tax statements, this is a reduction of taxable income, as a recognition of certain expenses required to produce the income. Income tax In income tax calculation, a write-off is the itemized deduction of an item's value from a person's taxable income. Thus, if a person in the United States has a taxable income of $50,000 per year, a $100 telephone for business use would lower the taxable income to $49,900. If that person is in a 25% tax bracket, the tax due would be lowered by $25. Thus the net cost of the telephone is $75 instead of $100. In order for business owners to write off business expenses, the IRS states that purchases must be both ordinary and necessary. This means that deductible items must be usual and required for the business owner's field of work. For example, a telemarketer may deduct the purchase of a phone, sin ...

Runway
According to the International Civil Aviation Organization (ICAO), a runway is a "defined rectangular area on a land aerodrome prepared for the landing and takeoff of aircraft". Runways may be a man-made surface (often asphalt concrete, asphalt, concrete, or a mixture of both) or a natural surface (sod, grass, soil, dirt, gravel, ice, sand or road salt, salt). Runways, as well as taxiways and Airport apron, ramps, are sometimes referred to as "tarmac", though very few runways are built using Tarmacadam, tarmac. Takeoff and landing areas defined on the surface of water for seaplanes are generally referred to as waterways. Runway lengths are now International Civil Aviation Organization#Use of the International System of Units, commonly given in meters worldwide, except in North America where feet are commonly used. History In 1916, in a World War I war effort context, the first concrete-paved runway was built in Clermont-Ferrand in France, allowing local company Michelin to ...

Hard Landing
A hard landing occurs when an aircraft or spacecraft hits the ground with a greater vertical speed and force than in a normal landing. Landing is the final phase in flight, in which the aircraft returns to the ground. The average vertical speed in a landing is around ; any greater vertical speed should be classed by crew as ''hard''. Crew judgment is most reliable to determine hard landing, as determination based on recorded acceleration value is difficult and not advisable, partially because there is no recording of true vertical acceleration. Hard landings can be caused by weather conditions, mechanical problems, overweight aircraft, pilot decision and/or pilot error. The term ''hard landing'' usually implies that the pilot still has total or partial control over the aircraft, as opposed to an uncontrolled descent into terrain (a crash). Hard landings can vary in their consequences, from mild passenger discomfort to vehicle damage, structural failure, injuries, and/or loss ...

Missed Approach
Missed approach is a procedure followed by a pilot when an instrument approach cannot be completed to a full-stop landing. The instructions for the missed approach may be assigned by air traffic control (ATC) prior to the clearance for the approach. If ATC has not issued specific instructions prior to the approach and a missed approach is executed, the pilot must follow the (default) missed approach procedure specified for the approach. Prior to commencing the approach, pilots can make a specific request to ATC if a missed approach may occur. Such a request may include heading and altitude instructions to avoid in-flight delays (such as holds) and efficiently maneuver the aircraft into position for either its next approach or a diversion to an alternate airport. Generally, if a pilot determines by the time the aircraft is at the decision height (for a precision approach) or missed approach point (for a non-precision approach), that the runway or its environment is not in sight, or ...

First Officer (aviation)
In aviation, the first officer (FO), also called co-pilot, is the pilot who is second-in-command of the aircraft 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. Control of the aircraft is normally shared equally between the first officer and the captain, with one pilot normally designated the "pilot flying" and the other the "pilot not flying", or "pilot monitoring", for each flight. Even when the first officer is the flying pilot, however, the captain remains ultimately responsible for the aircraft, its passengers, and the crew. In typical day-to-day operations, the essential job tasks remain fairly equal. Traditionally, the first officer sits on the right-hand side of a fixed-wing aircraft ("right seat") and the left-hand side of a helicopter (the reason for this difference is related to, in many cases, the pilot flying being unable to release the right hand from the cyclic con ...
