ATFM

What is aircraft rotation delay?

Knock-on effect due to a delayed aircraft A knock-on effect is the main cause for what’s also known as rotational delay – i.e. when a flight is delayed because of the late arrival of an aircraft.

What is flow management in aviation?

Air traffic flow management (ATFM) is the regulation of air traffic in order to avoid exceeding airport or air traffic control capacity in handling traffic (hence the alternative name of Air Traffic Flow and Capacity Management – ATFCM), and to ensure that available capacity is used efficiently.

How does air traffic flow management work?

The Air Traffic Flow Management (ATFM) Portal is a web-based interface that allows airspace users, airport operators and other ATFM users to access pertinent ATFM information such as the Calculated Take-Off Time (CTOT) during the implementation of ATFM measures.

How long can a flight be delayed?

Airline polices vary about what constitutes a ”substantial“ delay. Federal rules mandate an airline cannot keep you in a plane on the tarmac more than three hours on a domestic flight, or four hours on an international flight, without returning the aircraft to the gate and letting passengers get off.

What percentage of flights are delayed?

Those numbers have increased since before the pandemic: According to U.S. Department of Transportation, on average airlines delayed 27 percent of flights in June 2019, and canceled 2 percent. Main reasons why companies are struggling and let down passengers now are the lack of staffing and severe weather.

What is ATFM delay?

ATFM delay is defined as the duration between the last Estimated Take-Off Time (ETOT) and the Calculated Take-Off Time (CTOT) allocated by the Network Manager. ATFM delay comprises both Airport ATFM delay] and En route ATFM delay.

What is the purpose of central flow control?

It is used to provide informa- tion to operational managers in every ATC centre, the CFMU and national air traffic authorities, so that they can monitor the traffic situation and have relevant data to hand. The CFMU cannot, by itself, create more air traffic capacity.

What is traffic management program?

A Ground Delay Program (GDP) is a traffic management procedure where aircraft are delayed at their departure airport in order to manage demand and capacity at their arrival airport. Flights are assigned departure times, which in turn regulates their arrival time at the impacted airport.

Do airlines wait for passengers?

It is unusual for planes to wait for connecting passengers, anywhere, though not unknown. The reason is that people on the flight that has to wait may themselves have connections at the far end, and they would then miss them.

Which airline has the worst delays?

Among the nation’s largest airlines, Southwest Airlines had the most delays, with 30 percent of flights running late, according to FlightAware, a flight tracking service. At American Airlines, 25 percent of flights were delayed, compared with 23 percent for United Airlines and 21 percent for Delta Air Lines.

What does ATFM stand for in air traffic management?

A time calculated and issued by the ATFM Unit, as a result of tactical slot allocation, at which a flight is expected to push back/vacate the parking position so as to meet a CTOT taking into account start and taxi time.

How is the ATFM system used in Australia?

The ATFM system is used for pre-tactical and tactical planning and managing the arrival flows associated with the major Australian airports of Sydney, Melbourne, Brisbane, and Perth. The system offers effective pre-tactical and tactical decision support for managing demand-capacity imbalances and reducing air traffic saturation.

What is the fundamental concept of ATFM 1.3?

Fundamental Concept of ATFM 1.3 Central to this CONOPS is the fundamental concept of balancing air traffic demand and capacity. While ANSPs and airport operators should strive to increase and optimize airspace and airport capacity to meet demand, traffic growth, surges in traffic and capacity constraining events cause imbalances.

What does CFMU stand for in air traffic management?

All IFR flight plans are tracked by a CFMU (central flow management unit). Each airport and air traffic control sector has a published maximum capacity. When capacity is exceeded, measures are taken to reduce the traffic. This is termed regulation.
