Boom Operator (military)
In the U.S. Air Force (USAF), a boom operator is an aircrew member aboard tanker aircraft who is responsible for safely and effectively transferring aviation fuel from one military aircraft to another during flight (known as ''aerial refueling'', ''air refueling'', ''in-flight refueling'', ''air-to-air refueling'', and ''tanking''). The name boom operator implies that one "operates a boom" (the ''flying boom''), which is a long, extendable metal arm attached to the rear underside of the ''tanker'' that the boom operator connects to the fuel receptacle of a receiving aircraft (the ''receiver''). The boom operator also controls the refueling ''drogue'', a basket attached to a flexible hose that trails the tanker, when using the probe-and-drogue system. The USAF officially designates the boom operator career field as "In-Flight Refueling" with a specialty code of 1A0X1. However, this designation is usually reserved for administrative paperwork such as enlistment contracts and per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircrew Badge
The Aircrew Badge, commonly known as Wings, is a qualification badge of the United States military that is awarded by all five branches of armed services to personnel who serve as aircrew members on board military aircraft. The badge is intended to recognize the training and qualifications required by aircrew of military aircraft. In order to qualify as an aircrew member and receive the Aircrew Badge, such personnel typically undergo advanced training in aircraft in-flight support roles. U.S. Army The first version of the Aircrew Badge was issued by the Army Air Forces during the Second World War. The badge was similar in design to the Aviator Badge, however, and displayed an emblem denoting enlisted status on its circular shield, or escutcheon, centered between two wings. The emblem featured the arms of the United States of America, in clear relief generally against a horizontally lined background, on a disk with a raised rim. Anyone trained in flight operations was a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aircraft Flight Manual
An aircraft flight manual (AFM) is a paper book or electronic information set containing information required to operate an aircraft of certain type or particular aircraft of that type (each AFM is tailored for a specific aircraft, though aircraft of the same type naturally have very similar AFMs). The information within an AFM is also referred to a Technical Airworthiness Data (TAWD). A typical flight manual will contain the following: operating limitations, Normal/Abnormal/Emergency operating procedures, performance data and loading information. An AFM will often include: * V speeds * Aircraft gross weight * Maximum ramp weight * Maximum takeoff weight * Manufacturer's empty weight * Operating empty weight * Centre of gravity limitations * Zero-fuel weight * Takeoff distance * Landing distance Originally, an AFM would follow whichever format and order the manufacturer felt appropriate. Eventually, the General Aviation Manufacturers Association came to an agreement to sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Force Specialty Code
The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth's surface, absorbing ultraviolet solar radiation, warming the surface through heat retention ( greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation). By mole fraction (i.e., by number of molecules), dry air contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere. Air composition, temperature, and atmospheric pressure vary with altitude. Within the atmosphere, air suitable for use in photosynthesis by terrestrial plants and breathing of terrestrial animals is f ...

Aerial Refueling
Aerial refueling, also referred to as air refueling, in-flight refueling (IFR), air-to-air refueling (AAR), and tanking, is the process of transferring aviation fuel from one aircraft (the tanker) to another (the receiver) while both aircraft are in flight. The two main refueling systems are ''probe-and-drogue'', which is simpler to adapt to existing aircraft, and the ''flying boom'', which offers faster fuel transfer, but requires a dedicated boom operator station. The procedure allows the receiving aircraft to remain airborne longer, extending its range or loiter time. A series of air refuelings can give range limited only by crew fatigue/physical needs and engineering factors such as engine oil consumption. As the receiver aircraft can be topped up with extra fuel in the air, air refueling can allow a takeoff with a greater payload which could be weapons, cargo, or personnel: the maximum takeoff weight is maintained by carrying less fuel and topping up once airborne.

Military Aircraft
A military aircraft is any Fixed-wing aircraft, fixed-wing or rotorcraft, rotary-wing aircraft that is operated by a legal or insurrectionary armed service of any type. Military aircraft can be either combat or non-combat: * Combat aircraft are designed to destroy enemy equipment or personnel using their own aircraft ordnance. Combat aircraft are typically developed and procured only by military forces. * Non-combat aircraft are not designed for combat as their primary function, but may carry weapons for self-defense. These mainly operate in support roles, and may be developed by either military forces or civilian organizations. History Lighter-than-air In 1783, when the first practical aircraft (hot-air and hydrogen balloons) were established, they were quickly adopted for military duties. The first military balloon unit was the French Aerostatic Corps, who in 1794 flew an observation balloon during the Battle of Fleurus (1794), Battle of Fleurus, the first major battle to ...

Aviation Fuel
Aviation fuels are petroleum-based fuels, or petroleum and synthetic fuel blends, used to power aircraft. They have more stringent requirements than fuels used for ground use, such as heating and road transport, and contain additives to enhance or maintain properties important to fuel performance or handling. They are kerosene-based ( JP-8 and Jet A-1) for gas turbine-powered aircraft. Piston-engined aircraft use leaded gasoline and those with diesel engines may use jet fuel (kerosene). By 2012, all aircraft operated by the U.S. Air Force had been certified to use a 50-50 blend of kerosene and synthetic fuel derived from coal or natural gas as a way of stabilizing the cost of fuel. Specific energy (energy per unit mass) is an important criterion in selecting fuel for an aircraft. The much higher energy storage capability of hydrocarbon fuels compared to batteries has so far prevented electric aircraft using electric batteries as the main propulsion energy store becoming via ...

List Of Tanker Aircraft
This is a list of tanker aircraft used for aerial refuelling of another aircraft whilst in powered flight. Refueling methods ;Looped hose: The first commercial method employed a hose which was held slack in a trailing half-loop behind both aircraft. The receiving aircraft flew just below the tanker and deployed a steel line, which the tanker caught with its own grappling line and drew in. The tanker then connected the first steel line to the refueling hose and paid it out as the receiving aircraft reeled it back in. ; Probe-and-drogue: The tanker trails a flexible hose with a stabilising drogue on the end and the receiving aircraft manoeuvers to insert a short probe into the receptacle in the drogue. ;Flying boom: The tanker extends a hinged telescopic boom with aerodynamic control surfaces on its end. An operator "flies" it to match up with a receptacle on the receiving aircraft, which then moves forwards to make the connection. ;Wing-to-wing: A hybrid method in which the tanke ...

Aircrew
Aircrew, also called flight crew, are personnel who operate an aircraft while in flight. The composition of a flight's crew depends on the type of aircraft, plus the flight's duration and purpose. Commercial aviation Flight deck positions In commercial aviation, the aircrew are called ''flight crew''. Some flight crew position names are derived from nautical terms and indicate a rank or command structure similar to that on ocean-going vessels, allowing for quick executive decision making during normal operations or emergency situations. Historical flightdeck positions include: * Captain, the pilot highest-ranking member or members of a flight crew. * First officer (FO, also called a co-pilot), another pilot who is normally seated to the right of the captain. (On helicopters, an FO is normally seated to the left of the captain, who occupies the right-hand seat).Smith, PatrickPatrick Smith's Ask The Pilot: When a Pilot Dies in Flight AskThePilot.com website, 2013, whic ...

International Military Intervention Against ISIL
In response to rapid territorial gains made by the so-called Islamic State during the first half of 2014, and its universally condemned executions, reported human rights abuses and the fear of further spillovers of the Syrian Civil War, many states began to intervene against it in both the Syrian Civil War and the War in Iraq. Later, there were also minor interventions by some states against IS-affiliated groups in Nigeria and Libya. In mid-June 2014, Iran, according to American and British information, started flying drones over Iraq, and, according to Reuters, Iranian soldiers were in Iraq fighting IS. Simultaneously, the United States ordered a small number of troops to Iraq and started flying crewed aircraft over Iraq. In July 2014, according to the International Institute for Strategic Studies, Iran sent Sukhoi Su-25 aircraft to Iraq, and Hezbollah purportedly sent trainers and advisers to Iraq in order to help Shia militias to monitor ISIL's movements. In August 2014, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
