| 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. | | Report an issue with this definition | source: FAA Aviation Maintenance Technician Airframe Handbook (FAA-H-8083-31) |

| 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.

Slot Aviation Definition Meaning
Slot Aviation Definition Science
Reagan National is routinely operating below 67 hourly takeoffs and landings ('slots')-the maximum number authorized in any one hour-mostly because general aviation or other unscheduled aircraft operations decreased substantially after new security restrictions were imposed following the September 11, 2001, terrorist attacks. Aviation industry calls for airport slot relief for summer 2021 season. Finally the WASB called for “clear definition for acceptable non-use of a slot”, allowing for “force majeure as a.
