Aviation in the context of "Helicopter"

Transport (in British English) or transportation (in American English) is the intentional movement of humans, animals, and goods from one location to another. Modes of transport include air, land (rail and road), water, cable, pipelines, and space. The field can be divided into infrastructure, vehicles, and operations. Transport enables human trade, which is essential for the development of civilizations.

Transport infrastructure consists of fixed installations, including roads, railways, airways, waterways, canals, and pipelines, as well as terminals such as airports, railway stations, bus stations, warehouses, trucking terminals, refueling depots (including fuel docks and fuel stations), and seaports. Terminals may be used both for the interchange of passengers and cargo and for maintenance.

A mode of transport is a method or way of travelling, or of transporting people or cargo. The different modes of transport include air, water, and land transport, which includes rails or railways, road and off-road transport. Other modes of transport also exist, including pipelines, cable transport, and space transport. Human-powered transport and animal-powered transport are sometimes regarded as distinct modes, but they may lie in other categories such as land or water transport.

In general, transportation refers to the moving of people, animals, and other goods from one place to another, and means of transport refers to the transport facilities used to carry people or cargo according to the chosen mode. Examples of the means of transport include automobile, airplane, ship, truck, and train. Each mode of transport has a fundamentally different set of technological solutions. Each mode has its own infrastructure, vehicles, transport operators and operations.

Land transport is the transport or purposeful movement of people, animals and/or goods from one location to another via land-based routes. This is in contrast with other main types of transport such as maritime transport, which moves over waterbodies; and aviation, which moves via flight through the atmosphere. The two main forms of land transport are rail transport and road transport.

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.

In mathematics, analytic geometry, also known as coordinate geometry or Cartesian geometry, is the study of geometry using a coordinate system. This contrasts with synthetic geometry.

Analytic geometry is used in physics and engineering, and also in aviation, rocketry, space science, and spaceflight. It is the foundation of most modern fields of geometry, including algebraic, differential, discrete and computational geometry.

London has an extensive and developed transport network which includes both public and private services. Journeys made on its integrated transport network account for 37% of London's journeys while private services accounted for 36% of journeys, walking 24% and cycling 2%, according to numbers from 2017. London's public transport network serves as the central hub for the United Kingdom in rail, air and road transport.

Public transport services are dominated by the city's executive agency for transport, Transport for London (TfL). TfL controls the majority of public transport, including the Underground, Buses, Tramlink, the Docklands Light Railway, London River Services, Elizabeth line and the London Overground.

Meteorology is the scientific study of the Earth's atmosphere and short-term atmospheric phenomena (i.e., weather), with a focus on weather forecasting. It has applications in the military, aviation, energy production, transport, agriculture, construction, weather warnings, and disaster management.

Along with climatology, atmospheric physics, atmospheric chemistry, and aeronomy, meteorology forms the broader field of the atmospheric sciences. The interactions between Earth's atmosphere and its oceans (notably El Niño and La Niña) are studied in the interdisciplinary field of hydrometeorology. Other interdisciplinary areas include biometeorology, space weather, and planetary meteorology. Marine weather forecasting relates meteorology to maritime and coastal safety, based on atmospheric interactions with large bodies of water.
