The leading edge slot is an aerodynamic feature of the wing of some airplanes to reduce the stall speed and promote good low-speed handling qualities. A leading edge slot is a span-wise gap in each wing, allowing air to flow from below the wing to its upper surface. For an arrival slot request, there is NO blank between action code and flight number. The scheduled time of arrival (STA) is stated without a blank after the airport of origin. An airport slot, landing slot, or takeoff slot can be described as permission granted to a specific airline by the operator of the airport. This critical period guarantees the airline in question the permission to take off and land at the airport during a specified time. 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. 'Leading edge slot' by Sanchom - Own work. Licensed under CC BY 3.0 via Commons. A number of airliners use movable slats, in which case, the system is called slat, rather than slot. Following the creation of a single market for aviation in the 1990s, there was a need for a regulation on slots. These are defined as permission to use the full range of airport infrastructure necessary to operate an air service on a specific date and time for landing or take-off.
Slot - A set time when runway is assigned for a flight to take-off or land.
Standby - Is the situation when a traveller without a reservation
is waiting for a seat on a flight to become available. The passenger
is usually asked to report to the gate shortly before departure.
Slot A specially-shaped slot in the wing just behind the leading edge. This directs airflow from below to the top of the wing, and helps low-speed flight by delaying the stall. Because they are permanently-mounted, they do add drag. See also 'Slats'
Slow Roll A very slow version of the roll.
SLOT - A long, narrow, spanwise gap in a wing, usually near the leading edge, to improve airflow at high angles of attack for slower landing speeds.
SLOTTED FLAP - A flap that, when depressed, exposes a slot and increases airflow between itself and the rear edge of the wing.

SLOW TAXI- To taxi a floatplane at low power or low RPM.
~ - The gap between the slat and leading-edge of the main airfoil, which splits the airflow and maintains a smooth flow over the main airfoil upper surface.
SPAN - The distance from tip to tip of the wing or tailplane.
The ~ incorporated into the junction between the main wing and the plain flap in the slotted flap arrangement allows airflow from under the wing to energise (i.e. accelerate and smooth) the turbulent boundary layer flow over the upper surface of the lowered flap.

The most expensive fix is construction of a leading edge ~. A 'cuff' or drooped leading edge may be used, a series of protrusions on the upper wing surface may be used to direct air flow even to the extent of being full chord 'fences' to prevent span-wise flow.
It follows that if we guide air through a narrowing ~ (a funnel) it must go faster and faster to get through and if the exit is smaller than the entrance we have a definite suction at the exit.
A ~ acts as a duct to force high-energy air down on the upper surface of the wing when the airplane is fling at a high angle of attack. The ~, 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.
The frise-type aileron also forms a ~ so air flows smoothly over the lowered aileron, making it more effective at high angles of attack. Frise-type ailerons may also be designed to function differentially. Like the differential aileron, the frise-type aileron does not eliminate adverse yaw entirely.
The receiver needs to set its own clock to the correct time ~. It does this by trying all the possible values. This process may take one or two seconds. In many GPS receivers this stage of the proceedings is shown on the display by the satellite acquisition histogram bar becoming visible as a hollow bar.
This is a small wing like device installed ahead of the wing leading edge so that the air can flow in between the slat and wing (~) at high angles of attack. Nowadays you will find automatically retractable slats as the fixed type creates a lot of drag at higher speeds.
We use a pump to create a supply of air at very high pressure.
The air comes out a nozzle. The result is a jet of high-velocity air at the same pressure as the local air.8
The jet shoots out of a ~ in the top of the wing, adding energy to the boundary layer at a place where this could be very helpful.
All suppliers are not created equal and it is absolutely necessary the builder sort out the rotten apples before tossing the envelope in the mail ~.
Not only must your heading be precise, but your altitude is critical--and you must judge both of these visually. In particular, you must be at an altitude that will clear the base of the launch pad, but be below the gantry arms. You'll be flying through a little square ~.

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]
Airport capacity[edit]
Slot Aviation Definition
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.

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.
