Utility Helicopter
A utility helicopter is a multi-purpose helicopter capable of fulfilling many different roles. Civil Many civilian helicopters are made for utility work such as agricultural aircraft. Many police and fire departments maintain and operate utility helicopters to augment their regular forces. In many countries local hospital services operate medevac helicopters for special time-sensitive cases. Military A utility military helicopter can fill roles such as ground attack, air assault, military logistics, CASEVAC, medical evacuation, command and control, and troop transport. Some overlap of terminology is inevitable with transport helicopter. Prominent examples of utility helicopters include the American Bell Huey family, Russian Mil Mi-2 series and the French Aérospatiale Alouette III.

Command And Control
Command and control (abbr. C2) is a "set of organizational and technical attributes and processes ... hatemploys human, physical, and information resources to solve problems and accomplish missions" to achieve the goals of an organization or enterprise, according to a 2015 definition by military scientists Marius Vassiliou, David S. Alberts, and Jonathan R. Agre. The term often refers to a military system. Versions of the United States Army ''Field Manual 3-0'' circulated circa 1999 define C2 in a military organization as the exercise of authority and direction by a properly designated commanding officer over assigned and attached forces in the accomplishment of a mission. A 1988 NATO definition is that command and control is the exercise of authority and direction by a properly designated individual over assigned resources in the accomplishment of a common goal. An Australian Defence Force definition, similar to that of NATO, emphasises that C2 is the system empowering des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Utility Aircraft
A utility aircraft is a general-purpose light aircraft, light airplane or helicopter, usually used for transporting people, freight or other supplies, but is also used for other duties when more specialized aircraft are not required or available. The term can also refer to an aircraft type certificated under American, Canadian, European or Australian regulations as a ''Utility Category Aircraft'', which indicates that it is permitted to conduct limited aerobatics. The approved maneuvers include chandelles, Aerobatic maneuver, lazy eights, Spin (aerodynamics), spins and Steep turn (aviation), steep turns over 60° of bank.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 535. Aviation Supplies & Academics, 1997. In the United States, military utility aircraft are given the prefix U in their United States Department of Defense aerospace vehicle designation, designations.

Cargo Hook (helicopter)
A cargo hook is a device suspended below a helicopter and allows the transport of external loads during flight. Common terms for this operation include slingwork, underslung loads, external loadwork, and external load operations. Hook types Primary hooks Primary, or "belly", hooks are designed to mount directly to the airframe belly, i.e. underside, of a helicopter. Because they are attached to the fuselage, or "skin," of the aircraft, belly hooks are regulated by the various worldwide aviation regulatory agencies. In the United States, belly hooks are governed under Federal Aviation Administration (FAA) FAR Part 133. Belly hooks are designed, manufactured, and approved for use on specific aircraft models. Belly hooks that have been certified by the FAA receive a Supplemental Type Certificate (STC) that describes the aircraft models that are authorized to use the hook for external load operations. For example, a belly hook approved for use by the FAA on a Eurocopter AS350 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aérospatiale Alouette III
The Aérospatiale Alouette III (, ''Lark''; company designations SA 316 and SA 319) is a single-engine, light utility helicopter developed by France, French aircraft company Sud Aviation. During its production life, it proved to be a relatively popular rotorcraft; including multiple Licensed production, licensed manufacturers, more than 2,000 units were built. The Alouette III was developed as an enlarged derivative of the earlier and highly successful Aérospatiale Alouette II, Alouette II. Sharing many elements with its predecessor while offering an extra pair of seats and other refinements, it quickly became a commercial success amongst both civil and military customers. Further variants were also developed; amongst these was a high-altitude derivative, designated as the Aérospatiale SA 315B Lama, SA 315B Lama, which entered operational service during July 1971. The Alouette III was principally manufactured by Aérospatiale; the type was also built under licence by Hindustan A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mil Mi-2
The Mil Mi-2 (NATO reporting name Hoplite) is a small, three rotor blade Soviet-designed multi-purpose helicopter developed by the Mil Moscow Helicopter Plant designed in the early 1960s, and produced exclusively by WSK "PZL-Świdnik" in Poland. Design and development The Mi-2 was produced exclusively in Poland, in the WSK "PZL-Świdnik" factory in Świdnik. The first production helicopter in the Soviet Union was the Mil Mi-1, modelled along the lines of the S-51 and Bristol Sycamore and flown by Mikhail Mil's bureau in September 1948. During the 1950s it became evident, and confirmed by American and French development, that helicopters could be greatly improved with turbine engines. S. P. Isotov developed the GTD-350 engine and Mil used two of these in the far superior Mi-2. The twin shaft-turbine engines used in the Mi-2 develop 40% more power than the Mi-1's piston engines, for barely half the engine weight, with the result that the payload was more than doubled. The Mi- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Transport Helicopter
A military transport aircraft, military cargo aircraft or airlifter is a military-owned transport aircraft used to support military operations by airlifting troops and military equipment. Transport aircraft are crucial to maintaining supply lines to forward bases that are difficult to reach by ground or waterborne access, and can be used for both strategic and tactical missions. They are also often used for civilian emergency relief missions by transporting humanitarian aid. Air frames Fixed-wing Fixed-wing transport aeroplanes are defined in terms of their range capability as strategic airlift or tactical airlift to reflect the needs of the land forces which they most often support. These roughly correspond to the commercial flight length distinctions: Eurocontrol defines short-haul routes as shorter than , long-haul routes as longer than and medium-haul between. The military glider is an unpowered tactical air transport which has been used in some campaigns to tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airlift
An airlift is the organized delivery of supplies or personnel primarily via military transport aircraft. Airlifting consists of two distinct types: strategic and tactical. Typically, strategic airlifting involves moving material long distances (such as across or off the continent or theater), whereas a tactical airlift focuses on deploying resources and material into a specific location with high precision. Depending on the situation, airlifted supplies can be delivered by a variety of means. When the destination and surrounding airspace is considered secure, the aircraft will land at an appropriate airport or airbase to have its cargo unloaded on the ground. When landing the craft or distributing the supplies to a certain area from a landing zone by surface transportation is not an option, the cargo aircraft can drop them in mid-flight using parachutes attached to the supply containers in question. When there is a broad area available where the intended receivers have c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medical Evacuation
Medical evacuation, often shortened to medevac or medivac, is the timely and efficient movement and en route care provided by medical personnel to wounded being evacuated from a battlefield, to injured patients being evacuated from the scene of an accident to receiving medical facilities, or to patients at a rural hospital requiring urgent care at a better-equipped facility using medically equipped air ambulances, especially helicopters. Examples include civilian EMS vehicles, civilian aeromedical helicopter services, and military air ambulances. This term also covers the transfer of patients from the battlefield to a treatment facility or from one treatment facility to another by medical personnel, such as from a local hospital to a trauma center. History The first medical transport by air was recorded in Serbia in the autumn of 1915 during First World War. One of the ill soldiers in that first medical transport was Milan Rastislav Štefánik, a Slovak pilot-volunteer who was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helicopter
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Munson 1968.Hirschberg, Michael J. and David K. Dailey"Sikorsky". ''US and Russian Helicopter Development in the 20th Century'', American Helicopter Society, International. 7 July 2000. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most comm ...

CASEVAC
Casualty evacuation, also known as CASEVAC or by the callsign Dustoff or colloquially Dust Off, is a military term for the emergency patient evacuation of casualties from a combat zone. Casevac can be done by both ground and air. "DUSTOFF" is the callsign specific to U.S. Army Air Ambulance units. CASEVACs by air today are almost exclusively done by helicopter, a practice begun on a small scale toward the end of World War II; before that, STOL aircraft, such as the Fieseler Fi 156 or Piper J-3 were used. The primary difference between a CASEVAC and a medical evacuation (MEDEVAC) is that a MEDEVAC uses a standardized and dedicated vehicle providing en route care, while a CASEVAC uses non-standardized and non-dedicated vehicles that may or may not provide en route care. CASEVACs are commonly referred to as "a lift/flight of opportunity". If a corpsman/medic on the ground calls for a CASEVAC, the closest available unit with space could be called to assist, regardless of its medi ...
