Helipad in the context of Helicopter

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.

The Jumeirah Burj Al Arab (Arabic: برج العرب, lit. 'Arab Tower'), commonly known as Burj Al Arab, is a luxury hotel in Dubai, United Arab Emirates. Developed and managed by Jumeirah, it is one of the tallest hotels in the world, although 39% of its total height is made up of non-occupiable space. Burj Al Arab stands on an artificial island that is 280 m (920 ft) from Jumeirah Beach and is connected to the mainland by a private curving bridge. The shape of the structure is designed to resemble the sail of a dhow. It has a helipad near the roof, at a height of 210 m (689 ft) above ground.

The original Two World Trade Center (also known as the South Tower, Tower 2, Building Two, or 2 WTC) was one of the Twin Towers in the original World Trade Center Complex in New York City. The Tower was completed and opened in 1973 at a height of 1,362 feet (415 m) to the roof, distinguishable from its twin, the North Tower (1 World Trade Center), by the absence of a television antenna. On the 107th floor of this building was a popular tourist attraction, "Top of the World Trade Center Observatories," and on the roof was an outdoor observation deck accessible to the public and a disused helipad at the center. The address of this building was 2 World Trade Center, with the WTC complex having its own ZIP code of 10048.

The South Tower was destroyed along with the North Tower in the September 11 attacks. At 9:03 a.m, seventeen minutes after its twin was hit, the South Tower was struck by United Airlines Flight 175. Although it was the second of the two skyscrapers to be hit by a hijacked airliner, it was the first to collapse, at 9:59 a.m., after burning for 56 minutes. Of the 2,977 victims killed in the attacks, around 1,000 were in the South Tower or on the ground.

A heliport is a small airport which has a helipad, suitable for use by helicopters, powered-lift craft, and other types of vertical-lift aircraft.

Designated heliports typically contain one or more touchdown and liftoff areas and may also have limited facilities such as fuel or hangars. In some larger towns and cities, customs facilities may also be available. The broader term vertiport refers to take-off/landing sites for all aircraft landing vertically.

Takeoff or take-off is the phase of flight during which an aerial vehicle leaves the ground and becomes airborne. For space vehicles that launch vertically, this is known as liftoff.

For fixed-wing aircraft that take off horizontally (conventional takeoff), this usually involves an accelerating ground run (known as the roll) on a runway to build up speed so the wings can generate enough lift. For aerostats (balloons and airships), helicopters, tiltrotors (e.g. the V-22 Osprey) and thrust-vectoring STOVL fixed-wing aircraft (e.g. the Harrier jump jet and F-35B), a helipad/STOLport is sufficient and no runway is needed.

A carrier-based aircraft (also known as carrier-capable aircraft, carrier-borne aircraft, carrier aircraft or aeronaval aircraft) is a navalised aircraft designed for seaborne flight operations from aircraft carriers. The term is generally applied only to shipborne fixed-wing aircraft that require a runway of some sort for takeoff and landing, as VTOL aircraft such as helicopters are inherently capable of adapting to flight operations from a wide variety of ships (not just aircraft carriers) as long as the served vessel is equipped with helipads or a sufficiently spacious deck that can provide a reliable landing area, which include helicopter carriers, amphibious assault ships, aviation-capable surface combatants (cruisers, destroyers, frigates and some corvettes), container ships and even cruiseliners.

Carrier-based aircraft are designed for many purposes including aerial combat, surface attack, anti-submarine warfare (ASW), search and rescue (SAR), carrier onboard delivery (COD), weather observation, reconnaissance and airborne early warning and control (AEW&C). Such aircraft must be able to take off from the short distance available on the carrier's flight deck and be sturdy enough to withstand the abrupt forces exerted by on a pitching deck due to sea waves. Some modern carrier aircraft are designed for catapult-assisted takeoffs and thus also need to be constructed more robust airframes and landing gears that can handle sudden forward accelerations. Arrestor hook is mandatory feature for those designed for CATOBAR or STOBAR landing, while thrust vectoring or tiltrotor nacelles are commonly seen in those capable of V/STOL operations. In addition, their wings are generally larger (thus can generate more lift) than the land-launched counterparts, and are typically able to fold up or swing back for taxiing, pushback and parking in tight quarters.

Yambaru (山原) is the Okinawan and Kunigami name given to the forested northern part of Okinawa Island in Japan. Spanning the northern villages of Higashi, Kunigami, and Ōgimi, Yambaru contains some of the last large surviving tracts of subtropical rainforest in Asia, with many endemic species of flora and fauna. Many southerners fled to the area for refuge during the Battle of Okinawa. In 2016, Yambaru National Park was established and the area was included in a submission for inscription on the UNESCO World Heritage List.

Yambaru currently contains the 7,500 ha US Jungle Warfare Training Centre at Camp Gonsalves. As of 2010 there were twenty-two helipads in the training area with a further seven planned within two of the best preserved areas. Issues relating to the location of helipads delayed the designation as a National Park. Threatened by clearcutting and the removal of undergrowth, various endemic species are facing an imminent extinction crisis. The US Marine Corps has noted that 'to continue to perform realistic military training activities, these habitats must be maintained.'

St. Olav's University Hospital (Norwegian: St. Olavs Hospital - Universitetssykehuset i Trondheim) is the hospital in Trondheim, Norway located at Øya. It is part of St. Olavs Hospital Trust that operates all the hospitals in Sør-Trøndelag and thus indirectly state owned. It cooperates closely with the Norwegian University of Science and Technology in research and in education of medical doctors. The university is named for Olaf II of Norway, also known as St. Olav.

It performed 274,441 somatic and 88,692 psychiatric consultations in 2005 with 8,691 employees and a budget of Norwegian krone 5.1 billion. Trondheim Heliport, St. Olav's Hospital (ICAO: ENTR) is a helipad located adjacent to the emergency ward. It opened on 1 February 2010 and has a fuel tank.

A vertiport (verti- is for vertical and port for harbour, analogous to airport) is a future, as yet rarely realised concept of a take-off and landing site for electrically powered aircraft taking off and landing vertically, eVTOL craft. It can be part of a vertihub if there is a large volume of air traffic. A vertiport is similar to a heliport or helipad.

The Palace of the Republic (German: Palast der Republik, pronounced [paˈlast deːɐ ʁepuˈbliːk]) was a building in Berlin that hosted the Volkskammer, the parliament of East Germany, from 1976 to 1990.

Also known as the "People's Palace", it was located across the Unter den Linden from Museum Island in the Mitte area of East Berlin, on the site of the former Berlin Palace, which had been heavily damaged by Allied air raids and demolished in the 1950s. It was located between the Lustgarten and Schlossplatz, near the West Berlin border. The palace was completed in 1976 to house the Volkskammer, also serving various cultural purposes including two large auditoria, art galleries, a theatre, a cinema, 13 restaurants, five beer halls, a bowling alley, billiards rooms, a rooftop ice skating rink, a private gym with spa, a casino, a medical station, a post office, a police station with an underground cellblock, a fire station, an indoor basketball court, an indoor swimming pool, private barbershops and salons, public and private restrooms and a discothèque. In the early 1980s, one of the restaurants was replaced by a video game arcade for children of Volkskammer members and staff. The palace also had its own subway station, secure underground parking garage reserved for Central Committee members and a helipad reserved for Politburo members.
