2024 Alaska Air Fuel Douglas C-54 Crash
On April 23, 2024, a Douglas C-54D operated by Alaska Air Fuel crashed near the Tanana River shortly after takeoff, killing both crew members. The aircraft, transporting Aviation fuel, fuel from Fairbanks International Airport in Fairbanks, Alaska, to Kobuk Airport in Kobuk, Alaska, Kobuk, Alaska, suffered a failure on the outboard Aircraft engine, engine on the left wing shortly after takeoff. The crew attempted to resolve the failure and return to the airport, but a fuel explosion resulted in part of the aircraft's aileron controls separating. The crew were unable to recover from the subsequent Loss of control (aeronautics), loss of control. The investigation, conducted by the National Transportation Safety Board (NTSB), found that the maintenance done to the left outboard engine did not fix the dripping fuel tank located behind the engine, causing fuel to drip into the space between it and the engine. The wreckage showed that the nut used to connect the Feathering (propeller), p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loss Of Control (aeronautics)
In aeronautics, loss of control (LOC) is the unintended departure of an aircraft from controlled flight and is a significant factor in several Aviation accidents and incidents, aviation accidents worldwide. In 2015 it was the leading cause of general aviation accidents. Loss of control may be the result of mechanical failure, external disturbances, aircraft upset conditions, or inappropriate crew actions or responses. Causes Loss of control causes aircraft to depart from normal flight and possibly reach altitudes or encounter situations from which it can be difficult or impossible to recover, such as a Stall (fluid dynamics), stall or a Spin (aerodynamics), spin. Due to the certification and design processes, it is extremely rare for aircraft to experience a loss of control without extreme mishandling or a technical defect. A NASA study focused on identifying causal factors and addressing mitigation challenges related to aircraft loss of control had developed a preliminary list o ...

List Of Alaska Routes
Alaska Routes are both numbered and named. There have been only twelve state highway numbers issued (1 through 11 and 98), and the numbering often has no obvious pattern. For example, Alaska Route 4 (AK-4) runs north and south, whereas AK-2 runs largely east and west, but runs north and south passing through and to the north of Fairbanks. The Klondike Highway, built in 1978, was unnumbered until 1998, when it was given its designation during the centennial of the Klondike Gold Rush. However, many Alaskan highways of greater length than the Klondike Highway remain unnumbered. Mileposts, frequently used for road markers and official addressing in rural areas, are also more commonly reckoned by landmark names. Within Alaska, roads are almost invariably referred to by name or general destination, and not by number(s). Numbered routes often span multiple highway names. For example, AK-1 can refer to any of the Glenn Highway, Seward Highway, Sterling Highway, or Tok Cut-Off; mean ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flight Hours
Flight time or block time is an aviation term referring to the total amount of time spent piloting aircraft, and serves as the primary measure of a pilot's experience. Flight time is defined by International Civil Aviation Organization (ICAO) as "The total time from the moment an aeroplane first moves for the purpose of taking off until the moment it finally comes to rest at the end of the flight", and thus includes time spent taxiing and performing pre-flight checks on the ground, provided the engine is running. It is colloquially referred to as "blocks to blocks" or " chocks to chocks" time. In commercial aviation, this means the time from pushing back at the departure gate to arriving at the destination gate. Air time is defined as "the time from the moment an aircraft leaves the surface until it comes into contact with the surface at the next point of landing". For gliders without self-launch capability, flight time "commences when the glider is towed for the purpose of fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Co-pilot
In aviation, the first officer (FO), also called co-pilot, is a pilot in addition 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. Requirement Historically, large aircraft had several personnel on the flight deck, such as a navigator, a flight engineer, and a dedicated radio operator. Improvements in automation and reliability have reduced this to two. Many aircraft require a minimum of two flight crew. The minimum crew requirement will be stated in the aircraft manuals by the manufacturer. In the European Union, all turbo-propeller aeroplanes with a maximum approved passenger seating configuration of more than nine and all turbo-jet aeroplanes require two pilots.EU OPS (965) Subpart N, Ops 1.940 Composition of flight crew Role Control of the aircraft is normally shared equally between the first officer and the captain, with one pilot normally designated the " pilot flying" an ...

Pratt & Whitney R-2000 Twin Wasp
The Pratt & Whitney R-2000 Twin Wasp is an American radial engine developed in 1942 to power military aircraft. It is one of the Pratt & Whitney Wasp series of Radial engines. Design and development The R-2000 was an enlarged version of the Pratt & Whitney R-1830 Twin Wasp, with focus on reducing the manufacturing costs and fuel requirements. The Bore (engine), bore was increased to , while it still retained the stroke. This brought displacement up to . There were a number of detail changes from the R-1830, such as front-mounted instead of rear-mounted ignition magneto, magnetos (as with the larger, and earlier Pratt & Whitney R-2800, Double Wasp), plain bearings for the crankshaft rather than roller bearings, and 87 octane fuel (specified because there were fears wartime supplies of 100 octane might fall short, but those fears were groundless). The R-2000 produced at 2,700 rpm with 87 octane fuel, with 100 octane fuel and at 2,800 rpm with 100/130-grade fuel. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aerial Firefighting
Aerial firefighting, also known as waterbombing, is the use of aircraft and other aerial resources to Wildfire suppression, combat wildfires. The types of aircraft used include fixed-wing aircraft and helicopters. Smokejumpers and rappellers are also classified as aerial firefighters, delivered to the fire by parachute from a variety of fixed-wing aircraft, or rappelling from helicopters. Chemicals used to fight fires may include water, water enhancers such as Fire-fighting foam, foams and Fire-retardant gel, gels, and specially formulated fire retardants such as Phos-Chek. Terminology The idea of fighting forest fires from the air dates back at least as far as Friedrich Karl von Koenig-Warthausen's observations on seeing a blaze when overflying the Santa Lucia Range, California, in 1929. A wide variety of terminology has been used in the popular media for the aircraft (and methods) used in aerial firefighting. The terms airtanker or air tanker generally refer to fixed-wing air ...

Aero Union
Aero Union Corporation was an aircraft operation and maintenance company based in Chico, California, United States. It was known for operating aerial firefighting aircraft, training crews and making custom designed firefighting systems tailored to specific aircraft requirements. After years of controversies regarding the operation of the company and the safety of its aircraft, the U.S. Forest Service (USFS) canceled its contract, and the company was forced to shut down soon after. History In 1960 Dale Newton and Dick Foy participated in their first fire season with a surplus B-25 Mitchell. Newton & Foy operated for that season under the name Western Air Industries. The following year they purchased their first two B-17 Flying Fortresses and changed their name to Aero Union. In 1962, the company moved their operations from Redding, California to Chico.

Aircraft Registration
An aircraft registration is a code unique to a single aircraft, required by international convention to be marked on the exterior of every civil aircraft. The registration indicates the aircraft's country of registration, and functions much like an automobile license plate or a ship registration. This code must also appear in its Certificate of Registration, issued by the relevant civil aviation authority (CAA). An aircraft can only have one registration, in one jurisdiction, though it is changeable over the life of the aircraft. Legal provisions In accordance with the Convention on International Civil Aviation (also known as the Chicago Convention), all civil aircraft must be registered with a civil aviation authority (CAA) using procedures set by each country. Every country, even those not party to the Chicago Convention, has an NAA whose functions include the registration of civil aircraft. An aircraft can only be registered once, in one jurisdiction, at a time. The NAA a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
