Runway in the context of "Bagram Air Base"

An airport is an aerodrome with extended facilities, mostly for commercial air transport. They usually consist of a landing area, which comprises an aerially accessible open space including at least one operationally active surface such as a runway for a plane to take off and to land or a helipad, and often includes adjacent utility buildings such as control towers, hangars and terminals, to maintain and monitor aircraft. Larger airports may have airport aprons, taxiway bridges, air traffic control centres, passenger facilities such as restaurants and lounges, and emergency services. In some countries, the US in particular, airports also typically have one or more fixed-base operators, serving general aviation.

Airport operations are extremely complex, with a complicated system of aircraft support services, passenger services, and aircraft control services contained within the operation. Thus airports can be major employers, as well as important hubs for tourism and other kinds of transit. Because they are sites of operation for heavy machinery, a number of regulations and safety measures have been implemented in airports, in order to reduce hazards. Additionally, airports have major local environmental impacts, as both large sources of air pollution, noise pollution and other environmental impacts, making them sites that acutely experience the environmental effects of aviation. Airports are also vulnerable infrastructure to extreme weather, climate change caused sea level rise and other disasters.

Naval aviation is the application of military air power by navies, either from warships that can embark aircraft (e.g. aircraft carriers, amphibious assault ships and aircraft cruisers) or from coastal naval air stations.It often involves navalised aircraft, specifically designed for naval use.Seaborne aviation encompasses similar activities not restricted to navies, including marines and coast guards, such as in U.S. naval aviators. As with most army aviation units, naval aviation units are generally separate from a nation's dedicated air force.

Naval aviation operations are typically projected by way of carrier-based aircraft, which must be sturdy enough to withstand the demands of shipborne operations at sea. They must be able to take off from a short runway (typically the flight deck of an aircraft carrier) and be sturdy and flexible enough to come to a sudden stop when landing; they typically have robust folding or swinging wings that reduce the occupied space and thus allow more of them to be stored in below-decks hangars and limited parking spaces on flight decks. These aircraft are designed for many tactical purposes, including aerial combat, airstrike/close air support, anti-submarine warfare, early warning, search and rescue, matériel transport, weather observation, patrol and reconnaissance, and wide-area command and control duties.

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 short take-off and landing (STOL) or short take-off and vertical landing (STOVL) aircraft cannot perform without a runway.

The Focke-Wulf Fw 61 was the first successful, practical, and fully controllable helicopter in 1936, while in 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production. Starting in 1939 and through 1943, Igor Sikorsky worked on the development of the VS-300, which over four iterations, became the basis for modern helicopters with a single main rotor and a single tail rotor.

In aviation, an intersection is a virtual navigational fix that helps aircraft maintain their flight plan. It is usually defined as the intersection (in the geometrical sense) of two VOR (VHF Omnidirectional Range) radials. They are usually identified as major airway intersections where aircraft, operating under instrument flight rules, often change direction of flight while en route. According to the Federal Aviation Regulations, some intersections are designated as mandatory reporting points for pilots who are not in radar contact with air traffic control.

Intersections also play an important role in departure and approach procedures. All intersections have an alphabetical or alphanumeric designation. Near major airports, the intersection designation code typically consists of three letters followed by the runway number. Most other intersection designations consist of five-letter combinations that are either pronounceable or chosen for their mnemonic value, since either air traffic control or the flight plan may require the pilot to announce the designation. In the terminal procedure or approach plate example to the right, note that two of the intersections are called DONUT and KOFFE. Many intersections are named because of local points of interest. In the case of Carroll County Airport, there is a popular diner located on the field to which many pilots fly.

The airport apron, apron, flight line, or ramp is the area of an airport where aircraft are parked, unloaded or loaded, refueled, boarded, or maintained. Although the use of the apron is covered by regulations, such as lighting on vehicles, it is typically more accessible to users than the runway or taxiway. However, the apron is not usually open to the general public, and a permit may be required to gain access. An apron's designated areas for aircraft parking are called aircraft stands.

By extension, the term apron is also used to identify the air traffic control (ATC) position responsible for coordinating movement on this surface at busier airports. When the aerodrome control tower does not have control over the apron, the use of the apron may be controlled by an apron management service (also known as apron control or apron advisory) to provide coordination between the users. Apron control allocates aircraft parking stands (gates) and communicates this information to tower or ground control and to airline handling agents; it also authorises vehicle movements where they could conflict with taxiing aircraft such as outside of painted road markings. The authority responsible for the aprons is also responsible for relaying to ATC information about the apron conditions such as water, snow, construction or maintenance works on or adjacent to the apron, temporary hazards such as birds or parked vehicles, systems failure etc. Procedures should be established for a coordinated information provision between the aircraft, vehicle, apron control unit and ATC to facilitate the orderly transition of aircraft between the apron management unit and the aerodrome control tower.

An international airport is an airport with customs and border control facilities, enabling passengers to travel between countries around the world. International airports are usually larger than domestic airports, and feature longer runways and have facilities to accommodate heavier aircraft such as the Boeing 747 and the Airbus A380 commonly used for international and intercontinental travel. International airports often host domestic flights, which helps feed both passengers and cargo into international ones (and vice versa).

Buildings, operations, and management have become increasingly sophisticated since the mid-20th century, when international airports began to provide infrastructure for international civilian flights. Detailed technical standards have been developed to ensure safety and common coding systems implemented to provide global consistency. The physical structures that serve millions of individual passengers and flights are among the most complex and interconnected in the world. By the second decade of the 21st century, over 1,200 international airports existed with around 3.8 billion international passengers as of January 2023 along with 50 million metric tonnes of cargo passing through them annually.

A cluster munition is a form of air-dropped or ground-launched explosive weapon that releases or ejects smaller submunitions. Commonly, this is a cluster bomb that ejects explosive bomblets that are designed to kill personnel and destroy vehicles. Other cluster munitions are designed to destroy runways or electric power transmission lines.

Because cluster bombs release many small bomblets over a wide area, they pose risks to civilians both during attacks and afterwards. Unexploded bomblets can kill or maim civilians and unintended targets long after a conflict has ended, and are costly to locate and remove. This failure rate ranges from 2 percent to over 40 percent.

An aircraft catapult is an acceleration device used to help fixed-wing aircraft reach liftoff speed (V_LOF) faster during takeoff, typically when trying to take off from a very short runway, as otherwise the aircraft engines alone cannot get the aircraft to sufficient airspeed quickly enough for the wings to generate the lift needed to sustain flight. Launching via catapults enables aircraft that typically are only capable of conventional takeoffs, especially heavier aircraft with significant payloads, to perform short takeoffs from the roll distances of light aircraft. Catapults are usually used on the deck of a ship — such as the flight deck of an aircraft carrier — as a form of assisted takeoff for navalised aircraft, but can also be installed on land-based runways, although this is rare.

Historically it was most common for seaplanes (which have pontoons instead of wheeled landing gears and thus cannot utilize runways) to be catapulted from ships onto nearby water for takeoff, allowing them to conduct aerial reconnaissance missions and be crane-hoisted back on board during retrieval, although by the late First World War their roles are largely supplanted by the more versatile biplanes that can take off and land on carrier decks unassisted. During the Second World War before the advent of escort carriers, monoplane fighter aircraft (notably the Hawker Hurricane) would sometimes be catapulted from "catapult-equipped merchant" (CAM) vessels for one-way sorties to repel enemy aircraft harassing shipping lanes, forcing the returning pilot to either divert to a land-based airstrip, jump out by parachute, or ditch in the water near the convoy and wait for rescue. By the time fleet carriers became the norm in WW2, catapult launches have become largely unnecessary and carrier-based fighter-bombers would routinely perform self-powered takeoffs and landings off and onto carrier decks, especially during the naval aviation-dominated Pacific War between the United States and the Empire of Japan. However, escalating arms races during the Cold War accelerated the adoption of the heavier jet aircraft for naval operations, thus motivating the development of new catapult systems, especially after the popularization of angled flight decks further limited the practical distance available as takeoff runways. Nowadays, jet aircraft can launch from aircraft carriers via either catapults or ski-jump deck, and perform optics-assisted landing onto the same ship with help from decelerative arresting gears.

Bagram Airfield-BAF, also known as Bagram Air Base (IATA: OAI, ICAO: OAIX), is located 11 kilometres (6.8 mi) southeast of Charikar in the Parwan Province of Afghanistan. It is owned and operated by the country's Ministry of Defense. Sitting on the site of the ancient town of Bagram at an elevation of 1,492 metres (4,895 ft) above sea level, the air base has two concrete runways. The main one measures 3,602 by 46 metres (11,819 ft × 151 ft), capable of handling large military aircraft, including the Lockheed Martin C-5 Galaxy. The second runway measures 2,953 by 26 metres (9,687 ft × 85 ft). The air base also has at least three large hangars, a control tower, numerous support buildings, and various housing areas. There are also more than 13 hectares (32 acres) of ramp space and five aircraft dispersal areas, with over 110 revetments.

Bagram Airfield was built by the Soviet Union in the 1950's. Bagram Air Base was formerly the largest U.S. military base in Afghanistan, staffed by the 455th Air Expeditionary Wing of the U.S. Air Force, along with rotating units of the U.S. and coalition forces. It was expanded and modernized by the Americans. There is also a hospital with 50 beds, three operating theatres and a modern dental clinic. Kabul International Airport is located approximately 40 km (25 mi) south of Bagram, connected by two separate roads.
