What Is a Slot?


A Slot is a narrow opening that is authorized for an aircraft to land or take off at a specific airport. A slot is an important management tool used to ensure that no one flight is delayed repeatedly because another plane had to land there. A slot may also refer to an opening within an interior copy desk. A slot is also a job position at a newspaper. A slot may also be a job position within an air traffic management organization, such as EUROCONTROL.

In the United States, there are few restrictions on the use of slots. Nevada, for example, permits them in casinos and small shops. In Indiana and Louisiana, slot machines are permitted on riverboats only, but the barge requirement was removed in Mississippi after Hurricane Katrina. In Delaware, slots may be found in three horse tracks and are regulated by the state lottery commission. In Wisconsin, bars can have up to five machines in their establishments.

A Slot can include multiple slots or none of them. The bot will identify each slot and map it to the entity it should be mapped to. For example, a booking of a hotel can map to a built-in slot, while a custom slot can map to a date or type of room requested. A Slot can be added to an utterance by clicking on the Uterance or Slots tab. A slot is also defined by entering the name of the slot.
