Standard Instrument Departure Route (SID)
A Standard Instrument Departure Route (SID) is a predetermined route that pilots follow after takeoff from an airport. They are published instrument flight rules (IFR) routes that are used to facilitate the safe passage of aircraft after departure. SIDs assist pilots in transitioning from departure to en route flight by providing a standard path to follow and keeping aircraft separated from each other and other obstacles, such as mountains or buildings. SIDs are designed to maximize safety and efficiency by providing clearances and vectors for aircraft to follow. They are tailored to specific airports, taking into account their location, terrain, and surrounding airspace, and are designed to minimize noise impact on local communities. Pilots are required to follow the specified route to enable efficient and safe separation from other aircraft and to maintain compliance with air traffic control instructions.
