Slot Aviation Definition

1. Additionally, the board has requested a “clear definition for acceptable non-use of a slot.” “Airlines and airports need certainty as they are already planning the 2021 summer season (which begins in April) and have to agree schedules,” IATA’s outgoing director general Alexandre de Juniac said.
2. Slot sales, on the other hand, are less favourably regarded, mainly on the grounds that smaller airlines would have difficulty matching the deep pockets of the larger carriers. It sees slot sales as a way of increasing slot availability to smaller airlines, provided dominant carriers are prevented from adding significantly to their slot holdings.

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. Report an issue with this definition source: Wikitionary / Wikipedia and Related Sources (Edited)

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. 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.

slat Auxiliary curved or mini-aerofoil surface designed to prevent flow breakaway from a wing or tail. On a tail leading-edge it may be fixed, leaving a narrow slot.

slat
A movable auxiliary airfoil on the leading edge of a wing. The slat extends into the flow of air and creates a gap that allows air to flow smoothly over the top of the wing, delaying the stall at high angles of attack.

~ - Auxiliary airfoil surface, mounted forward of a main airfoil, to maintain a smooth airflow over the main airfoil at high angles of attack.
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.

Figure 4 - Fixed Leading Edge ~Lift vs. Drag
But there is a simple solution: The amount of drag increase created by the slot depends on the amount of air going through the slot in the whole range of flight. In take-off and landing configurations we want maximum lift, and in cruise we want minimum drag.

This is a small wing like device installed ahead of the wing leading edge so that the air can flow in between the ~ and wing (slot) at high angles of attack. Nowadays you will find automatically retractable ~s as the fixed type creates a lot of drag at higher speeds.
