In aviation, instrument flight rules (IFR) is one of two sets of regulations governing all aspects of civil aviation aircraft operations; the other is visual flight rules (VFR).
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 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.
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.
Controlled airspace is airspace of defined dimensions within which air traffic control (ATC) services are provided. The level of control varies with different classes of airspace. Controlled airspace usually imposes higher weather minimums than are applicable in uncontrolled airspace. It is the opposite of uncontrolled airspace.
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.
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.
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).
Faisalabad International Airport is an international airport and standby Pakistan Air Force military base situated on Jhang Road, 10 kilometres (6.2 mi) southwest of the city centre of Faisalabad, in the Punjab province of Pakistan. The airport is home to two flying schools who use the airfield for regular training for new cadets and aviation enthusiasts.
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).
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.
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.
Special use airspace (SUA) is a type of special airspaces in the United States designated for operations of a nature such that limitations may be imposed on aircraft not participating in those operations. Often these operations are of a military nature. The designation of SUAs identifies for other users the areas where such activity occurs, provides for segregation of that activity from other users, and allows charting to keep airspace users informed of potential hazards.
The United States airspace system's classification scheme is intended to maximize pilot flexibility within acceptable levels of risk appropriate to the type of operation and traffic density within that class of airspace – in particular to provide separation and active control in areas of dense or high-speed flight operations.
Islamabad International Airport is an international airport serving Islamabad, the capital city of Pakistan and Rawalpindi. It is located 25 km (16 mi) south-west of the city, and is directly connected to the Lahore and Peshawar motorways as well to the capital city Islamabad via Srinagar Highway.
Montreal Area Control Centre is one of 7 Area Control Centres in Canada operated by Nav Canada. Montreal ACC is located in a building on the outskirts of Montréal–Pierre Elliott Trudeau International Airport.
Jinnah International Airport, formerly Drigh Road Airport or Karachi Civil Airport, is Pakistan's busiest international and domestic airport, and handled 7,267,582 passengers in 2017–2018. Located in Karachi, the largest city and commercial capital of Pakistan and capital of the province of Sindh, it is named after Muhammad Ali Jinnah, the statesman founder of Pakistan. It is one of the oldest airports in the world.
Toronto Area Control Center is one of seven area control centers in Canada operated by Nav Canada. The Toronto Area Control Centre is based near Toronto Pearson International Airport in Mississauga, Ontario.
Lahore Area Control Centre is one of three Area Control Centers in Pakistan operated by the Pakistan Civil Aviation Authority and based at Allama Iqbal International Airport in Lahore. Lahore ACC air traffic controllers provide en route and terminal control services to aircraft in the Lahore Flight Information Region (FIR). The Lahore FIR airspace covers Pakistani airspace between the 30° North to 37° North. To the south is the Karachi FIR. To the north is the Urumqi FIR. To the east is the Delhi FIR. To the west is the Kabul FIR.
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.
