Joint Precision Airdrop System
The Joint Precision Airdrop System (JPADS) is an American military airdrop system which uses the Global Positioning System (GPS), steerable parachutes, and an onboard computer to steer loads to a designated point of impact (PI) on a drop zone (DZ). The JPADS family of systems consists of several precision airdrop systems, ranging from extra light to heavy payloads. JPADS is used in conjunction with mission planning software that resides on a laptop. The function of this mission planning software includes computing release points, weather forecasting, acquiring measurements of wind velocity, altitude, air pressure, and temperature. It can also receive weather updates and en route mission changes through satellite links. History U.S. Army Research, Development and Engineering Command (RDECOM) was the primary developer for JPADS, which meets several requirements: increased ground accuracy, standoff delivery, increased air carrier survivability, and improved effectiveness/assessment f ...

Air Freight
Air cargo is any property carried or to be carried in an aircraft. Air cargo comprises air freight, air express and airmail. Aircraft types Different cargo can be transported by passenger, cargo or combi aircraft: * Passenger aircraft use the spare volume in the airplane's baggage hold (the "belly") that is not being used for passenger luggage—a common practice used by passenger airlines, who additionally transport cargo on scheduled passenger flights. Cargo can also be transported in the passenger cabin as hand-carry by an “on-board courier”. This practice can often be used to cross subsidise loss-making passenger routes that would otherwise be uneconomical to operate. A passenger aircraft can also be used as a preighter in which the entire passenger cabin is temporarily dedicated to carrying freight. * Cargo aircraft are dedicated for the job—they carry freight on the main deck and in the belly by means of nose-loading or side loading. * Combi aircraft carry cargo ...

High-altitude Military Parachuting
High-altitude military parachuting, or military free fall (MFF), is a method of delivering military personnel, military equipment, and other military supplies from a transport aircraft at a high altitude via free-fall parachute insertion. Two techniques are used: HALO (high altitude – low opening, often called a HALO jump) and HAHO (high altitude – high opening). In the HALO technique, the parachutist opens the parachute at a low altitude after free-falling for a period of time, while in the HAHO technique, the parachutist opens the parachute at a high altitude just a few seconds after jumping from the aircraft. Although HALO techniques were first developed in the 1960s for military use, in recent years HALO parachute designs have been more widely used in non-military applications, including as a form of skydiving. In military operations, HALO is also used for delivering equipment, supplies, or personnel, while HAHO is generally used exclusively for personnel. I ...

Static Line
A static line is a fixed cord attached to a large, stable object. It is used to open parachutes automatically for paratroopers and novice parachutists. Design and use A static line is a cord attached at one end to the aircraft and at the other end to the top of the jumper's "D-Bag" (deployment bag, into which the canopy is packed). The parachutist's fall from the aircraft causes the static line to become taut, this then pulls the D-Bag out of the container on the jumper's back. The static line and D-Bag stay with the aircraft as the jumper leaves, and are pulled back into the aircraft by the dispatcher. Now free of its D-Bag, the canopy is allowed to inflate as the jumper continues to fall. Effectively, the jumper drags the parachute behind him, causing the upward-rushing wind to force open and inflate the canopy. The canopy should inflate and begin supporting the jumper within four seconds. In the unlikely event of a malfunction, students are taught how to cut away the main ...

Paratrooper
A paratrooper is a military parachutist—someone trained to parachute into a military operation, and usually functioning as part of an airborne force. Military parachutists (troops) and parachutes were first used on a large scale during World War II for troop distribution and transportation. Paratroopers are often used in surprise attacks, to seize strategic objectives such as airfields or bridges. Overview Paratroopers jump out of airplanes and use parachutes to land safely on the ground. This is one of the three types of "forced entry" strategic techniques for entering a theater of war; the other two being by land and by water. Their tactical advantage of entering the battlefield from the air is that they can attack areas not directly accessible by other transport. The ability of air assault to enter the battlefield from any location allows paratroopers to evade emplaced fortifications that guard from attack from a specific direction. The possible use of paratrooper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airborne Forces
Airborne forces, airborne troops, or airborne infantry are ground combat units carried by aircraft and airdropped into battle zones, typically by parachute drop or air assault. Parachute-qualified infantry and support personnel serving in airborne units are also known as paratroopers. The main advantage of airborne forces is their ability to be deployed into combat zones without land passage, as long as the airspace is accessible. Formations of airborne forces are limited only by the number and size of their transport aircraft; a sizeable force can appear "out of the sky" behind enemy lines in merely hours if not minutes, an action known as ''vertical envelopment''. Airborne forces typically lack enough supplies for prolonged combat, so they are utilized for establishing an airhead to bring in larger forces before carrying out other combat objectives. Some infantry fighting vehicles have also been modified for paradropping with infantry to provide heavier firepower. Due t ...

Pathfinder (military)
In military organizations, a pathfinder is a specialized soldier inserted or dropped into place in order to set up and operate drop zones, pickup zones, and helicopter landing sites for airborne operations, air resupply operations, or other air operations in support of the ground unit commander. Pathfinders first appeared in World War II, where they served with distinction, and continue to serve an important role in today's modern armed forces, providing commanders with the option of flexibly employing air assets. History United Kingdom During the Second World War small groups of parachute soldiers were formed into pathfinder units, to parachute ahead of the main force. Their tasks were to mark the drop zones (DZ) or landing zones (LZ), set up radio beacons as a guide for the aircraft carrying the main force and to clear and protect the area as the main force arrived. The units were formed into two companies to work with the two British airborne divisions created during th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loadmaster
A loadmaster is an aircrew member on civilian aircraft or military transport aircraft tasked with the safe loading, transport and unloading of aerial cargoes. Loadmasters serve in the militaries and civilian airlines of many nations. Duties The loadmaster performs the calculations and plans cargo and passenger placement to keep the aircraft within permissible center of gravity limits throughout the flight. Loadmasters ensure cargo is placed on the aircraft in such a way as to prevent overloading sensitive sections of the airframe and cargo floor. Considerations are also given to civilian and military regulations which may prohibit the placement of one type of cargo in proximity to another. Unusual cargo may require special equipment to be loaded safely aboard the aircraft, limiting where the other cargo may feasibly be placed. Tactically, loadmasters may also directly affect combat readiness as they are also responsible for determining the load order of aircraft so that mor ...

Delivery Drone
A delivery drone is an unmanned aerial vehicle (UAV) used to transport packages for use cases that include medical supplies, fresh food, live ammunition, or other goods. Delivery drones are typically autonomous and electric, and operated as a part of a fleet. Applications Healthcare delivery Drones can be used to transport medicinal products such as blood products, vaccines, pharmaceuticals, and medical samples. Medical deliveries are able to fly into and out of remote or otherwise inaccessible regions, compared to trucks or motorcycles. Medical drone delivery is credited with saving lives during emergency deliveries of blood in Rwanda and post-hurricane relief in Puerto Rico. During the COVID-19 pandemic, drones made medical deliveries of personal protective equipment and COVID-19 tests in the United States, Israel, and Ghana. In partnership with the Ghana Ministry of Health, Zipline drones delivered thousands of COVID-19 vaccine vials in Ghana during 2020 and 2021. Universi ...

Knot (unit)
The knot () is a unit of speed equal to one nautical mile per hour, exactly (approximately or ). The ISO standard symbol for the knot is kn. The same symbol is preferred by the Institute of Electrical and Electronics Engineers (IEEE), while kt is also common, especially in aviation, where it is the form recommended by the International Civil Aviation Organization (ICAO). The knot is a non- SI unit. The knot is used in meteorology, and in maritime and air navigation. A vessel travelling at 1 knot along a meridian travels approximately one minute of geographic latitude in one hour. Definitions ;1 international knot = :1 nautical mile per hour (by definition), : (exactly), : (approximately), : (approximately), : (approximately) : (approximately). The length of the internationally agreed nautical mile is . The US adopted the international definition in 1954, having previously used the US nautical mile (). The UK adopted the international nautical mile definition in 1970, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
