As of 2021, Australia was the 12th-largest national economy by nominal GDP, the 18th-largest by PPP-adjusted GDP, and was the 25th-largest goods exporter and 20th-largest goods importer. Australia took the record for the longest run of uninterrupted GDP growth in the developed world with the March 2017 financial quarter. It was the 103rd quarter and the 26th year since the country had a technical recession. As of June 2021, the country's GDP was estimated at A$1.98 trillion. The Australian economy is dominated by its service sector, which in 2017 comprised 62.7% of the GDP and employed 78.8% of the labour force. Australia has the tenth-highest total estimated value of natural resources, valued at US$19.9 trillion in 2019. At the height of the mining boom in 2009–10, the total value-added of the mining industry was 8.4% of GDP. Despite the recent decline in the mining sector, the Australian economy had remained resilient and stable and did not experience a recession from 1991 until 2020. An airport is an aerodrome with extended facilities, mostly for commercial air transport. Airports usually consists 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. Operating airports is extremely complicated, with a complex system of aircraft support services, passenger services, and aircraft control services contained within the operation. Airports revenues are divided into three major parts: aeronautical revenue, non-aeronautical revenue, and non-operating revenue. Aeronautical revenue makes up 56%, non-aeronautical revenue makes up 40%, and non-operating revenue makes up 4% of the total revenue of airports. Air traffic control (ATC) is the task of managing aircraft movements and making sure they are safe, orderly and expeditious. At the largest airports, air traffic control is a series of highly complex operations that requires managing frequent traffic that moves in all three dimensions. Ground control is responsible for directing all ground traffic in designated "movement areas", except the traffic on runways. This includes planes, baggage trains, snowplows, grass cutters, fuel trucks, stair trucks, airline food trucks, conveyor belt vehicles and other vehicles.
