Air Traffic Control Tower
Air traffic control (ATC) is a service provided by ground-based air traffic controllers who direct aircraft on the ground and through a given section of controlled airspace, and can provide advisory services to aircraft in non-controlled airspace. The primary purpose of ATC is to prevent collisions, organise and expedite the flow of traffic in the air, and provide information and other support for pilots. Personnel of air traffic control monitor aircraft location in their assigned airspace by radar and communicate with the pilots by radio. To prevent collisions, ATC enforces traffic separation rules, which ensure each aircraft maintains a minimum amount of 'empty space' around it at all times. It is also common for ATC to provide services to all private, military, and commercial aircraft operating within its airspace; not just civilian aircraft. Depending on the type of flight and the class of airspace, ATC may issue ''instructions'' that pilots are required to obey, or '' ...

1956 Grand Canyon Mid-air Collision
The Grand Canyon mid-air collision occurred in the Western United States, western United States on June 30, 1956, when a United Air Lines Douglas DC-7 struck a Trans World Airlines Lockheed L-1049 Super Constellation over Grand Canyon National Park, Arizona. The first plane fell into the canyon while the other slammed into a rock face. All 128 on board both airplanes died, making it the first commercial airline incident to exceed one hundred fatalities. The airplanes had departed Los Angeles International Airport minutes apart from each other and headed for Chicago and Kansas City, Missouri, Kansas City, respectively. The collision took place in uncontrolled airspace, where it was the pilots' responsibility to maintain separation (aeronautics), separation ("see and be seen"). This highlighted the antiquated state of air traffic control, which became the focus of major aviation reforms.

Remote And Virtual Tower
Remote and virtual tower (RVT) is a modern concept where the air traffic service (ATS) at an airport is performed somewhere other than in the local control tower. Although it was initially developed for airports with low traffic levels, in 2021 it was implemented at a major international airport, London City Airport (84,260 aircraft movements in 2019). and proposed for the future Western Sydney Airport upon completion in 2026. The first remote tower implementation providing aerodrome ATS was approved and introduced into operations in Sweden in April 2015, with further implementations in other EASA Member States well underway. In 2019, Scandinavian Mountains Airport in Dalarna, Sweden has been the world's first airport built without a traditional tower, to be controlled remotely. The concept is also considered as contingency measures for major airports or for apron control only. As of 12 June 2023, Brașov-Ghimbav International Airport in Romania has implemented this change. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Single European Sky
The Single European Sky (SES) is a European Commission initiative that seeks to reform the European air traffic management system through a series of actions carried out in four different levels (institutional, operational, technological and control and supervision) with the aim of satisfying the needs of the European airspace in terms of capacity, safety, efficiency and environmental impact. Background Air traffic management in the European Union is currently undertaken by member states, co-operating through EUROCONTROL, an intergovernmental organisation that includes most of the European countries. European air spaces are some of the busiest in the world, and the current system of air traffic management allegedly suffers from several parameters, such as using national borders in the sky, and having large areas of airspace reserved for national military use when in fact they may not be needed. This has created 'an outdated patchwork of airspace blocs and inefficient flight pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
