What is the purpose of Standard Instrument Departures (SIDs) and Standard Terminal Arrival Routes (STARs)?

SIDs and STARs establish predefined, instrument-based routes for aircraft as they depart from and arrive at airports, to organize traffic flow and maintain separation. These published procedures specify the path an aircraft should follow, any altitude and speed constraints, and transitions to or from en route airways, which helps pilots and controllers anticipate routes, reduce workload, and improve efficiency in busy airspace. While ATC clearance is still required, a SID or STAR provides a standard, approved route rather than a random or improvised one. They are not used for weather monitoring, nor do they substitute for clearance. The routes are deliberate and published to distribute traffic predictably and safely.
