Bill Graham Helicopter Crash
On October 25, 1991, a Bell 206 carrying rock music concert promoter Bill Graham, his girlfriend Melissa Gold, and pilot Steve Kahn crashed into a transmission tower west of Vallejo, California, killing everyone on board. The cause of the accident was determined to be the pilot's intentional flight into known adverse weather conditions. Accident The Bell 206B JetRanger was operating under Federal Aviation Regulation Part 91, and departed from parking lot "F" of the Concord Pavilion around 9:45 pm, bound for the Commodore Center Heliport (KJMC) in Sausalito, California, about to the west-southwest. The pilot had received a weather briefing in which visual flight rules (VFR) flight was not recommended due to inclement weather. Before take-off, the pilot requested and received a special VFR clearance to pass through the airspace of Buchanan Field Airport on a northwest heading. When the helicopter lifted off, the weather was visibility, gusty winds, heavy rain, and overcast wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vallejo, California
Vallejo ( ; ) is a city in Solano County, California and the second largest city in the North Bay region of the Bay Area. Located on the shores of San Pablo Bay, the city had a population of 126,090 at the 2020 census. Vallejo is home to the California Maritime Academy, Touro University California and Six Flags Discovery Kingdom. Vallejo is named after Mariano Guadalupe Vallejo, the famed Californio general and statesman. The city was founded in 1851 on General Vallejo's Rancho Suscol to serve as the capital city of California, which it served as from 1852 to 1853, when the Californian government moved to neighboring Benicia, named in honor of General Vallejo's wife Benicia Carrillo de Vallejo. The following year in 1854, authorities founded the Mare Island Naval Shipyard, which defined Vallejo's economy until the turn of the 21st century. History Vallejo was once home of the Coastal Miwok as well as Suisunes and other Patwin Native American tribes. There are three co ...

Airline Transport Pilot Licence
The airline transport pilot license (ATPL), or in the United States of America, an airline transport pilot (ATP) certificate is the highest level of aircraft pilot certificate. In the United States, those certified as airline transport pilots (unconditional) are authorized to act as pilot in command on scheduled air carriers' aircraft under CFR 14 Part 121. In the UK, pilots must hold an ATPL before they can be pilot in command on an aircraft with nine or more passenger seats. Context Any pilot operating an aircraft for pay must start by obtaining a commercial pilot licence (CPL). Airline transport pilot certifications do not have special endorsements, such as an instrument rating, as airline transport pilots must already possess knowledge and training in these areas. However, aircraft heavier than 12,500 pounds still require pilots to have a "type rating" (specific to the make and model of aircraft) certification. Theoretical examination EASA The EASA ATPL requires ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vauxhall Helicopter Crash
On 16 January 2013, an Agusta A109 helicopter crashed in Vauxhall, London, after it collided with the jib of a construction crane attached to St George Wharf Tower. Two people died in the incident: the pilot, Pete Barnes, 50, and a pedestrian, Matthew Wood, 39, from Sutton in south London. Five people were taken to hospital and seven more were treated at the scene. The pilot had diverted because of poor visibility. The official report concluded he was probably unaware how close the tower was, and that the deaths were accidental. Barnes was an experienced helicopter pilot, flying commercially for many years – including having experience with the Great North Air Ambulance Service. History of the flight Barnes had been en route from Redhill Aerodrome to Elstree Airfield to collect a passenger, businessman Richard Caring, and then fly onwards to Yorkshire. Before the pilot had taken off, Caring called him twice on his mobile phone to suggest either delaying or cancelling the fli ...

Death Of Stevie Ray Vaughan
On the early morning of Monday, August 27, 1990, American musician Stevie Ray Vaughan was killed in a helicopter crash near East Troy, Wisconsin, at age 35. He was one of the most influential blues guitarists of the 1980s, described by the Rock and Roll Hall of Fame as "the second coming of the blues". Vaughan spent many of his last days performing with his band Double Trouble as the opening act for Eric Clapton at Alpine Valley Music Theatre. After the concert concluded, Vaughan and three members of Clapton's entourage boarded a helicopter that crashed into the side of a nearby ski hill shortly after takeoff. The Civil Air Patrol was notified of the crash at 4:30 am, and authorities were called to locate the scene of the accident. All five people were pronounced dead on arrival. The autopsy concluded that Vaughan suffered multiple internal injuries and died of exsanguination due to blunt trauma. At the inquest, the coroner found no evidence of drug or alcohol use and re ...

2006 Mercy Air Bell 412 Crash
The 2006 Mercy Air helicopter accident occurred on December 10, 2006, about 17:55 Pacific Standard Time, when a Bell 412SP helicopter, call sign "Mercy Air 2" impacted mountainous terrain near Hesperia, California and the Cajon Pass. The commercial helicopter pilot and two medical crew members were killed, and the helicopter was destroyed by impact forces and a postcrash fire. On July 30, 2008, the National Transportation Safety Board (NTSB) released its probable-cause report on the accident. According to the NTSB, the probable cause of the crash was "the pilot's inadvertent encounter with instrument meteorological conditions and subsequent failure to maintain terrain clearance." The dark night conditions, fog, and mountainous terrain were ruled to be contributing factors. Accident details The Bell 412SP helicopter took off on a cross-country repositioning flight from Loma Linda University Medical Center (94CL), Loma Linda, California, at 17:42, with a planned destination of Sou ...

Visibility
The visibility is the measure of the distance at which an object or light can be clearly discerned. In meteorology it depends on the transparency of the surrounding air and as such, it is unchanging no matter the ambient light level or time of day. It is reported within surface weather observations and METAR code either in meters or statute miles, depending upon the country. Visibility affects all forms of traffic: roads, sailing and aviation. The geometric range of vision is limited by the curvature of the earth and depends on the eye level and the height of the object being viewed. In geodesy, the atmospheric refraction must be taken into account when calculating geodetic visibility. Meteorological visibility Definition ICAO Annex 3 ''Meteorological Service for International Air Navigation'' contains the following definitions and note: :a) the greatest distance at which a black object of suitable dimensions, situated near the ground, can be seen and recognized when o ...

Sectional Chart
{{short description, Type of aeronautical chart In United States aviation, a sectional chart, often called a sectional for short, is a type of aeronautical chart designed for air navigation under visual flight rules (VFR). In Australia, Canada and some other countries, the equivalent charts used for visual flight are called VFR Navigation Charts (VNCs). A sectional chart shows topographical features that are important to aviators, such as terrain elevations, ground features identifiable from altitude (rivers, dams, bridges, buildings, etc.), and ground features useful to pilots (airports, beacons, landmarks, etc.). The chart also shows information on airspace classes, ground-based navigation aids, radio frequencies, longitude and latitude, navigation waypoints, navigation routes. Sectional charts are in 1:500,000 scale and are named for a city on the map. The Federal Aviation Administration (FAA) in the United States publishes over 50 charts covering the continental United Stat ...

Altitude Above Ground Level
In aviation, atmospheric sciences and broadcasting, a height above ground level (AGL or HAGL) is a height measured with respect to the underlying ground surface. This is as opposed to height above mean sea level (AMSL or HAMSL), height above ellipsoid (HAE, as reported by a GPS receiver), or height above average terrain (AAT or HAAT, in broadcast engineering). In other words, these expressions (AGL, AMSL, HAE, AAT) indicate where the "zero level" or "reference altitude" - the vertical datum - is located. Aviation A pilot flying an aircraft under instrument flight rules (typically under poor visibility conditions) must rely on the aircraft's altimeter to decide when to deploy the undercarriage and prepare for landing. Therefore, the pilot needs reliable information on the height of the plane with respect to the landing area (usually an airport). The altimeter, which is usually a barometer calibrated in units of distance instead of atmospheric pressure, can therefore be set in su ...

Instrument Flight Rules
In aviation, instrument flight rules (IFR) is one of two sets of regulations governing all aspects of civil aviation aircraft operations; the other is visual flight rules (VFR). The U.S. Federal Aviation Administration's (FAA) ''Instrument Flying Handbook'' defines IFR as: "Rules and regulations established by the FAA to govern flight under conditions in which flight by outside visual reference is not safe. IFR flight depends upon flying by reference to instruments in the flight deck, and navigation is accomplished by reference to electronic signals." It is also a term used by pilots and controllers to indicate the type of flight plan an aircraft is flying, such as an IFR or VFR flight plan. Basic information Comparison to visual flight rules It is possible and fairly straightforward, in relatively clear weather conditions, to fly an aircraft solely by reference to outside visual cues, such as the horizon to maintain orientation, nearby buildings and terrain features for n ...

National Transportation Safety Board
The National Transportation Safety Board (NTSB) is an independent U.S. government investigative agency responsible for civil transportation accident investigation. In this role, the NTSB investigates and reports on aviation accidents and incidents, certain types of highway crashes, ship and marine accidents, pipeline incidents, bridge failures, and railroad accidents. The NTSB is also in charge of investigating cases of hazardous materials releases that occur during transportation. The agency is based in Washington, D.C. It has four regional offices, located in Anchorage, Alaska; Denver, Colorado; Ashburn, Virginia; and Seattle, Washington. The agency also operates a national training center at its Ashburn facility. History The origin of the NTSB was in the Air Commerce Act of 1926, which assigned the United States Department of Commerce responsibility for investigating domestic aviation accidents. Before the NTSB, the Federal Aviation Administration's (FAA; at the t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Welding
Welding is a fabrication (metal), fabrication process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool, causing Fusion welding, fusion. Welding is distinct from lower temperature techniques such as brazing and soldering, which do not melting, melt the base metal (parent metal). In addition to melting the base metal, a filler material is typically added to the joint to form a pool of molten material (the weld pool) that cools to form a joint that, based on weld configuration (butt, full penetration, fillet, etc.), can be stronger than the base material. Pressure may also be used in conjunction with heat or by itself to produce a weld. Welding also requires a form of shield to protect the filler metals or melted metals from being contaminated or Oxidation, oxidized. Many different energy sources can be used for welding, including a gas flame (chemical), an electric arc (electrical), a laser, an electron ...
