Standard Instrument Departure Routes and Standard Arrival Routes (SIDs and STARs)

Description

• A Standard Instrument Departure Route (SID) is a standard ATS route identified in an instrument departure procedure by which aircraft should proceed from take-off phase to the en-route phase.
• A Standard Terminal Arrival Route (STAR) is a standard ATS route identified in an approach procedure by which aircraft should proceed from the en-route phase to an initial approach fix.

(EUROCONTROL EATM Glossary of Terms)

SIDs and STARs are produced with the object of expediting the safe and efficient flow of air traffic operating to and from the same or different runways at the same or neighbouring airfields.
