Slot Aviation Definition

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.[1]

  • The slot, which is located ahead of the aileron, causes the inboard portion of the wing to stall fist, allowing the aileron to remain effective throughout the stall. Report an issue with this definition: source: FAA Aviation Maintenance Technician Airframe Handbook (FAA-H-8083-31).

Airport capacity[edit]

“An airport slot stands for all the time and infrastructure which one aircraft needs to land and to take off. At Helsinki Airport slots are given between 5 minutes, and their use is monitored constantly,” shares Tiina Nokkala, slot coordinator at Helsinki Airport. Nokkala is the only professional flight slot coordinator in Finland. SLOT - The gap between the and leading-edge of the main airfoil, which splits the airflow and maintains a smooth flow over the main airfoil upper surface. Some /slot systems also have the effect of increasing wing area thus reducing W/S and stall speed.

Because only one aircraft can land or depart from a runway at a given time, and because aircraft must be separated by a certain distance or time to avoid collisions, every airport has a finite capacity; it can safely handle only so many aircraft per hour. This capacity depends on many factors, such as the number of runways available, layout of taxi tracks, availability of air traffic control, and current or anticipated weather.[2] The weather can cause large variations in capacity; strong winds may limit the number of runways available, and poor visibility may necessitate increases in separation between aircraft.[3]

When an air traffic control unit that will control a flight reaches capacity, arriving aircraft are directed towards holding patterns where they circle until it is their turn to land. However, aircraft flying in circles is an inefficient and costly way of delaying aircraft, so it is preferable to keep them on the ground at their place of departure, called a ground delay program.[1] This way, the delay can be waited out on the ground with engines off, saving considerable amounts of fuel. The careful calculation of en route time for each flight and traffic flow as a whole, which aims to minimize overall delays in the air traffic system, is highly dependent on computers.

Operation in Europe[edit]

All IFRflight plans are tracked by the Central Flow Management Unit (CFMU). Every 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. The aim is to use capacity effectively, keeping the average delay as low as possible, while ensuring capacity is not exceeded.[4]

For example, if two flights are scheduled to arrive at an airport at exactly the same time, and the airport can handle one aircraft every five minutes, the aircraft may be assigned delays to ensure that the second aircraft arrives five minutes after the first. Similarly, the first aircraft will be required to depart on schedule and not allowed to depart late. This way, the second aircraft will not need to enter a holding pattern before landing.

Slat
A secondary control on an aircraft that allows it to fly at a high angle of attack without stalling. A slat is a section of leading edge of wing mounted on curved tracks that move into and out of the wing on rollers.

Slats are aerodynamic surfaces on the leading edge of the wings of fixed-wing aircraft which, when deployed, allow the wing to operate at a higher angle of attack. A higher coefficient of lift is produced as a result of angle of attack and speed, so by deploying slats an aircraft can fly at slower speeds, or take off and land in shorter distances. They are usually used while landing or performing maneuvers which take the aircraft close to the stall, but are usually retracted in normal flight to minimize drag.

Types include:

  • Automatic – the slat lies flush with the wing leading edge until reduced aerodynamic forces allow it to extend by way of aerodynamics when needed. Sometimes referred to as Handley-Page slats.
  • Fixed – the slat is permanently extended. This is sometimes used on specialist low-speed aircraft (these are referred to as slots) or when simplicity takes precedence over speed.
  • Powered – the slat extension can be controlled by the pilot. This is commonly used on airliners.
