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 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.
SIDs and STARs aim to deconflict potentially conflicting traffic by the use of specific routings, levels and check points. Typically, each runway will have a number of SIDs and STARs to ensure that air traffic is not unnecessarily delayed by deviation from the direct route from or to the aerodrome.
The SID or STAR which a pilot intends to use is usually included in the ATC flight plan.
