In aviation, visual flight rules (VFR) are a set of regulations under which a pilot operates an aircraft in weather conditions generally clear enough to allow the pilot to see where the aircraft is going. Specifically, the weather must be better than basic VFR weather minima, i.e., in visual meteorological conditions (VMC), as specified in the rules of the relevant aviation authority. The pilot must be able to operate the aircraft with visual reference to the ground, and by visually avoiding obstructions and other aircraft.
Air traffic control (ATC) is a service provided by ground-based air traffic controllers (people) 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 worldwide is to prevent collisions, organise and expedite the flow of traffic in the air, and provide information and other support for pilots.
In aviation, uncontrolled airspace is airspace in which an Air Traffic Control (ATC) service is not deemed necessary or cannot be provided for practical reasons. It is the opposite of controlled airspace. It is that portion of the airspace that has not been designated as Control Area, Control Zone, Terminal Control Area or Transition Area.
Airspace is the portion of the atmosphere controlled by a country above its territory, including its territorial waters or, more generally, any specific three-dimensional portion of the atmosphere. It is not the same as outer space which is the expanse or space outside the Earth and aerospace which is the general term for Earth's atmosphere and the outer space within the planet's vicinity.
Shanwick is the air traffic control (ATC) name given to the area of international airspace which lies above the northeast part of the Atlantic Ocean.
The world's navigable airspace is divided into three-dimensional segments, each of which is assigned to a specific class. Most nations adhere to the classification specified by the International Civil Aviation Organization (ICAO) and described below, though they might use only some of the classes defined below, and significantly alter the exact rules and requirements. Similarly, individual nations may also designate special use airspace (SUA) with further rules for reasons of national security or safety.
A NOTAM is a notice filed with an aviation authority to alert aircraft pilots of potential hazards along a flight route or at a location that could affect the flight. NOTAMs are notices or advisories that contain information concerning the establishment, conditions or change in any aeronautical facility, service, procedure or hazard, the timely knowledge of which may be essential to personnel and systems concerned with flight operations.
Special visual flight rules are a set of aviation regulations under which a pilot may operate an aircraft. It is a special case of operating under visual flight rules (VFR).

A flight information service (FIS) is a form of air traffic service which is available to any aircraft within a flight information region (FIR), as agreed internationally by ICAO.
In air traffic control, an area control center (ACC), also known as a center or en-route center, is a facility responsible for controlling aircraft flying in the airspace of a given flight information region (FIR) at high altitudes between airport approaches and departures. In the US, such a center is referred to as an air route traffic control center (ARTCC).
The Airports Authority of India (AAI) is a statutory body under the ownership of the Ministry of Civil Aviation, Government of India. It is responsible for creating, upgrading, maintaining, and managing civil aviation infrastructure in India. It provides Communication Navigation Surveillance/Air Traffic Management (CNS/ATM) services over the Indian airspace and adjoining oceanic areas. AAI currently manages a total of 137 airports, including 34 international airports, 10 Customs Airports, 81 domestic airports, and 23 Civil enclaves at Defence airfields. AAI also has ground installations at all airports and 25 other locations to ensure the safety of aircraft operations. AAI covers all major air routes over the Indian landmass via 29 Radar installations at 11 locations along with 700 VOR/DVOR installations co-located with Distance Measuring Equipment (DME). 52 runways are provided with Instrument landing system (ILS) installations with Night Landing Facilities at most of these airports and an Automatic Message Switching System at 15 Airports.
Air traffic control in Australia is provided by two independent organisations, one civilian and one military. The civilian provider is Airservices Australia, which controls civilian airfields and airspace. The military provider is the Royal Australian Air Force (RAAF), which controls military airfields and adjoining airspace. This includes Australian Army and Royal Australian Navy aviation bases.
The Australian Advanced Air Traffic System (TAAATS), is the hardware and software system used by Airservices Australia for air traffic control services. It is a paperless, computer-based system, which serves as an aid to civilian air traffic controllers. It does not control aircraft, but gives the user a display of information about an aircraft's position and associated information. It also handles communications and other information exchanges.
Pakistan Civil Aviation Authority (PCAA) is a state-owned autonomous body under the administrative control of the Secretary to the Government of Pakistan for Aviation, which oversees and regulates all aspects of civil aviation in Pakistan. PCAA's head office is situated in Terminal-1 of Jinnah International Airport in Karachi. PCAA is a member state of the International Civil Aviation Organization. Nearly all 44 civilian airports in Pakistan are owned and operated by the PCAA.
In aviation, an air traffic service (ATS) is a service which regulates and assists aircraft in real-time to ensure their safe operations. In particular, ATS is to:
The Riau Islands Flight Information Region is a proposed Flight Information Region (FIR) situated above the Riau Islands, which is a province of Indonesia comprising the principal group of the Riau Archipelago along with other island groups to the south, east and northeast. It is currently part of the Singapore FIR under the administration of the Singapore civil aviation authorities as a result of an arrangement by the International Civil Aviation Organization (ICAO) in 1946.
The Kabul Area Control Centre was the only en route area control center (ACC) in Afghanistan. From the Kabul Area Control Centre, air traffic controllers provided en route and terminal control services to aircraft in the Kabul Flight Information Region (FIR). The ACC was managed by the Civil Aviation Authority of the Islamic Republic of Afghanistan.
