SID’s & STAR’s

Departure Procedures

• Departure procedures are preplanned routes that provide transitions from the departure airport to the en route structure

• These procedures are designed to provide obstacle protection for departing aircraft

• Also allow for efficient routing of traffic and reductions in pilot/controller workloads

• Based on the design criteria outlined in TERPS and other FAA orders

Design

• The design of a departure procedure is based on TERPS,• a living document that is updated frequently

• Departure design criterion assumes an initial climb of 200 feet per nautical mile (NM) after crossing the departure end of the runway (DER) at a height of at least 35 feet

Location

• Located in the TERPS with the entries for the destination airport

• Graphic• Textual

Three Categories of DP’s

• Non-RNAV DP• Established for aircraft equipped with conventional

avionics using ground-based NAVAIDs

• RNAV DP• Established for aircraft equipped with RNAV

avionics; e.g., GPS, VOR/DME, DME/DME, etc

• Radar DP• Radar DPs are established when ATC has a need to

vector aircraft on departure to a particular ATS Route, NAVAID, or Fix

Two Types of DP’s

• Obstacle Departure Procedures (OPDs)• The term Obstacle Departure Procedure (ODP) is

used to define procedures that simply provide obstacle clearance

• Standard Instrument Departures (SIDs)• A Standard Instrument Departure (SID) is an ATC

requested and developed departure route, typically used in busy terminal areas

Acronyms

• DER• ROC• OCS• PCG• TORA• TODA• ASDA• LDA

Planning for the Departure

• During planning, pilots need to determine whether or not the departure airport has an ODP

• Will also need to determine if the aircraft can comply with those restrictions

• When close-in obstacles are noted in the Takeoff Minimums and (Obstacle) Departure Procedures section, it may require the pilot to take action to avoid these obstacles.

Standard Terminal Arrival Routes

• Provides a critical form of communication between pilots and ATC

• Route• Altitude• Airspeed• Provides a common method for leaving the

enroute structure and navigating to your destination

Location

• STARs are included at the front of each Terminal Procedures Publication regional booklet
