In aviation, a standard terminal arrival route (STAR) is a published flight procedure followed by aircraft on an instrument flight rules (IFR) flight plan just before reaching a destination airport. A STAR is an air traffic control (ATC)-coded IFR arrival route established for application to arriving IFR aircraft destined for certain airports.
The STARS system receives and processes target reports, weather, and other non-target messages from both terminal and en route digital sensors. Additionally, it automatically tracks primary and secondary surveillance targets and provides aircraft position information to the enhanced traffic management system (ETMS).
Inbound aircraft to London Heathrow Airport typically follow one of a number of Standard Terminal Arrival Routes (STARs The STARs each terminate at one of four different RNAV waypoints (co-located with VOR navigational aids), and these also define four "stacks" [1] where aircraft can be held, if necessary, until they are cleared to begin their approach to land.
Flight tracking enables travellers as well as those picking up travellers after a flight to know whether a flight has landed or is on schedule, for example to determine whether it is time to go to the airport. Aircraft carry ADS-B transponders, which transmit information such as the aircraft ID, GPS position, and altitude as radio signals.
A STAR, or Standard Terminal Arrival Route, ('Standard Instrument Arrival' in the UK) defines a pathway into an airport from the airway structure. STARs can be associated with more than one arrival airport, which can occur when two or more airports are in proximity (e.g., San Francisco and San Jose).
The flight plan is generally determined on the ground, before departure either by the pilot for smaller aircraft or a professional dispatcher for airliners. It is entered into the FMS either by typing it in, selecting it from a saved library of common routes (Company Routes) or via an ACARS datalink with the airline dispatch center.
A blank and a filled-out example of a US en-route flight progress strip. There are many styles of progress strip layouts, but minor differences aside, a strip contains at least: Aircraft identification (e.g. aircraft registration or a flight number) Aircraft type as the relevant 4-letter ICAO designator (e.g. B744 for a Boeing 747-400)
Before landing, an aircraft follows an arrival procedure (standard terminal arrival route, or STAR), which defines a pathway from a waypoint on an airway to an airport runway, so that the aircraft can leave the airway system in a controlled manner. Much of the descent portion of a flight will take place on a STAR.
