Air traffic flow management (usually seen abbreviated as 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). Definition. Calculated Take Off Time (CTOT) - The time provided by the Central Flow Management Unit (CFMU), taking into account the European Civil Aviation Conference (ECAC) ATC flow situation, that an aircraft has been calculated to take off. The CTOT, also known as the ATFM (Air Traffic Flow Management) slot, has a tolerance of – 5 to . A leading edge slot is a fixed aerodynamic feature of the wing of some aircraft to reduce the stall speed and promote good low-speed handling qualities. A leading edge slot is a spanwise gap in each wing, allowing air to flow from below the wing to its upper surface.
Leading edge slot
Aghh, now reposted in paragraphs! Air from below the wing can accelerate through the slot towards the low pressure region above the wing, and exit from the slot moving parallel to the upper wing surface. How much interaction is there between ATC and the airlines regarding the available inbound and outbound slots in a heavy fog situation, and who is responsible for the negotiation on the individual slots available, given the reduction in arrivals and departures? For instance, if Belgian airspace was the only regulation for the flight in the previous example, changing the route to avoid Belgium and going via Germany instead might allow a flight to depart without delay, although the route might be a bit longer.

This is because they contribute to drag compared to an unslotted wing.
Whats meant by slot time?
Air traffic flow management usually seen abbreviated as 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. 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. 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.
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. 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. The aim is to use capacity effectively, keeping the average delay as low as possible, while ensuring capacity is not exceeded.
As a highly simplified example, if two flights are scheduled to arrive at an airport at exactly the same time, and the airport can handle one aircraft every 5 minutes, the aircraft may be assigned delays to ensure that the second aircraft arrives 5 minutes after the first.

The most common types are fixed slots, movable slats, leading edge flaps, and cuffs. This leads into my main question which is, what are the differences between a slat and a slot? If I were to get asked this by an examiner what would a good response be?
A leading edge slot is basically a spanwise opening in the wing. Slats are aerodynamic surfaces in the leading edge, which when deployed, allows the wing to operate at higher angle of attack. When deployed, the slat opens up a slot between itself and the wing. In some aircraft, the slats are fixed, which opens up a slot between the wing and the slat. In this case, the terms slot and slat are used interchangeably. Licensed under CC BY 3. A number of airliners use movable slats, in which case, the system is called slat, rather than slot.

However the paragraph preceding it states High-lift devices also can be applied to the leading edge of the airfoil. So is this a typo? Should the image say 'movable slat' instead of 'movable slot'? I guess it should be movable slat. Would it be fair to say that a slat is a movable device that creates or closes off a slot in the leading edge of the wing?

A computer programmed slot machine game will normally have 3, 5, 6, and 7 main spinning wheels. They open up a possible 20, 30, and 50 betting lines, increasing the chances of a big payout on any given spin, but also, of course, simultaneously increasing the amount that one can lose as well. With more reels and higher bet increments available, Jackpots on some slot machines can reach up to a million credits or more on single line bet.
Winning representations and bonus icons can now appear diagonally, in a zigzag form, or in many other lined combinations. They can also trigger fascinating video clips, special effects, and interactive bonus property. These types of characteristics have opened up a whole new and exciting virtual world in the online industry of the free slots. In this section you will familiarize yourself with the most essential elements of the interface that could be applied to every slot machine:.
People who enjoy three-reel machines usually do so because of their simplicity, plus their easy focus of anticipation as the third reel falls quickly after the first - presenting its outcome without delay. These types can have up to fifty paylines and a multitude of possible winning combinations. This is a major inequality in a gameplay, as compared to the old three reel ones. Popular five reel ones are The Mega Moolah which has 30 betting lines, and also Spin or Reels at 20 paylines.
