Multi-purpose Helicopter
A utility helicopter is a multi-purpose helicopter capable of pursuing a wide array of tasks. They have proven useful in both civilian and military operations, with versatility being their defining trait. Civilian Helicopters play a crucial role in various aspects of civilian safety. Police and fire rescue aircraft demonstrate exceptional versatility across a broad spectrum of tasks. Common applications for civilian utility include traffic surveillance, medical evacuations, news coverage, and search and rescue missions. Recently, usage has been extended to air Emergency evacuation, evacuations, air and water pollution control, emergency cargo transportation (including blood, organs, and special equipment), and as helitankers in aerial firefighting. Traditionally, helicopters with three placed Reciprocating engine, reciprocating engines, such as the Bell 47, 47G Series and the Schweizer S300, Hughes 300C were the primary choices for civilian use. However, the preference has b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Infrared
Infrared (IR; sometimes called infrared light) is electromagnetic radiation (EMR) with wavelengths longer than that of visible light but shorter than microwaves. The infrared spectral band begins with the waves that are just longer than those of red light (the longest waves in the visible spectrum), so IR is invisible to the human eye. IR is generally (according to ISO, CIE) understood to include wavelengths from around to . IR is commonly divided between longer-wavelength thermal IR, emitted from terrestrial sources, and shorter-wavelength IR or near-IR, part of the solar spectrum. Longer IR wavelengths (30–100 μm) are sometimes included as part of the terahertz radiation band. Almost all black-body radiation from objects near room temperature is in the IR band. As a form of EMR, IR carries energy and momentum, exerts radiation pressure, and has properties corresponding to both those of a wave and of a particle, the photon. It was long known that fires e ...

Utility Aircraft
A utility aircraft is a general-purpose light airplane or helicopter, usually used for transporting people, freight, or other supplies, but 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, lazy eights, spins The spins (as in having "the spins") is an adverse reaction of Substance intoxication, intoxication that causes a state of vertigo and nausea, causing one to feel as if "spinning out of control", especially when lying down.

Ground Proximity Warning System
A Ground Proximity Warning System (GPWS) is a system designed to alert pilots if their aircraft is in immediate danger of flying into the ground or an obstacle. The United States Federal Aviation Administration (FAA) defines GPWS as a type of terrain awareness and warning system (TAWS). More advanced systems, introduced in 1996, are known as enhanced ground proximity warning systems (EGPWS), a modern type of TAWS. History In the late 1960s, a series of controlled flight into terrain (CFIT) accidents took the lives of hundreds of people. A CFIT accident is one where a properly functioning airplane under the control of a fully qualified and certified crew is flown into terrain, water or obstacles with no apparent awareness on the part of the crew.Note: Original text copied from U.S. FAA Circular AC23-1.

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 civil aviation authority, aviation regulatory agencies. In the United States, belly hooks are governed under Federal Aviation Administration (FAA) Federal Aviation Regulations, 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 Type certificate#Supplementary/Supplemental Type Certificate (STC), Supplemental Type Certificate (STC) that describes the aircraft models that are authorized ...

Strategic Goal (military)
A strategic military goal is used in strategic military operation plans to define the desired end-state of a war or a campaign. Usually it entails either a strategic change in an enemy's military posture, intentions or ongoing operations, or achieving a strategic victory over the enemy that ends the conflict, although the goal can be set in terms of diplomatic or economic conditions, defined by purely territorial gains, or the evidence that the enemy's will to fight has been broken. Sometimes the strategic goal can be to limit the scope of the conflict. Description It is the highest level of organisational achievement in a military organisation, and is usually defined by the national defence policy. In terms of goal assignment it corresponds to operations performed by a front or a fleet on a theatre scale, and by an Army group or, during the World War II, by a Red Army Front. A strategic goal is achieved by reaching specific strategic objectives that represent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military Operation
A military operation (op) is the coordinated military actions of a state, or a non-state actor, in response to a developing situation. These actions are designed as a military plan to resolve the situation in the state or actor's favor. Operations may be of a combat or non-combat nature and may be referred to by a code name for the purpose of national security. Military operations are often known for their more generally accepted common usage names than their actual operational objectives. Types of military operations Military operations can be classified by the scale and scope of force employment, and their impact on the wider conflict. The scope of military operations can be: * Theater: this describes an operation over a large, often continental, area of operation and represents a strategic national commitment to the conflict, such as Operation Barbarossa, with general goals that encompass areas of consideration outside the military, such as the economic and political imp ...

Military Exercise
A military exercise, training exercise, maneuver (manoeuvre), or war game is the employment of military resources in Military education and training, training for military operations. Military exercises are conducted to explore the effects of warfare or test tactics and strategies without actual combat. They also ensure the combat readiness of garrisoned or deployable forces prior to deployment from a home base. While both war games and military exercises aim to simulate real conditions and scenarios for the purpose of preparing and analyzing those scenarios, the distinction between a war game and a military exercise is determined, primarily, by the involvement of actual military forces within the simulation, or lack thereof. Military exercises focus on the simulation of real, full-scale military operations in controlled hostile conditions in attempts to reproduce war time decisions and activities for training purposes or to analyze the outcome of possible war time decisions.

Fire Support
Fire support is a military tactics term used to describe weapons fire used to support friendly forces by engaging, suppressing, or destroying enemy forces, facilities, or materiel in combat. It is often provided through indirect fire, though the term may also be used for some forms of supporting direct fire. The United States Department of Defense defines fire support as " fires that directly support land, maritime, amphibious, and special operations forces to engage enemy forces, combat formations, and facilities in pursuit of tactical and operational objectives." Overview Fire support generally consists of fire from heavy or crew-served weaponry with high firepower, including strikes and barrages from artillery, mortars, rocket artillery, and missiles; naval gunfire support from naval artillery; airstrikes, strafes, and close air support from military aircraft; and drone strikes from unmanned combat aerial vehicles; among various other forms.

UH-1Y Venom Okinawa (cropped)
The Bell UH-1Y Venom (also called Super Huey) is a twin-engine, 4-blade, medium-sized utility helicopter built by Bell Helicopter under the H-1 upgrade program of the United States Marine Corps. One of the latest members of the numerous Bell Huey family, Huey family, the UH-1Y is also called "Yankee" for the NATO phonetic alphabet pronunciation of its variant letter. Bell was originally to produce UH-1Ys by rebuilding UH-1Ns, but ultimately used new built airframes. In 2008, the UH-1Y entered service with the Marine Corps and also began full-rate production. The new UH-1 variant replaced the USMC's Bell UH-1N Twin Huey, UH-1N Twin Huey light utility helicopters, introduced in the early 1970s. The helicopter (and related Bell AH-1Z Viper) were ordered by the Czech Republic and the helicopter is in production in the early 2020s. Visually, some features that differentiate the Y model are a slightly longer cabin and larger twin engine exhaust vents compared to the earlier N model. ...

Radar
Radar is a system that uses radio waves to determine the distance ('' ranging''), direction ( azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain. The term ''RADAR'' was coined in 1940 by the United States Navy as an acronym for "radio detection and ranging". The term ''radar'' has since entered English and other languages as an anacronym, a common noun, losing all capitalization. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwave domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
