STAR Procedures (Standard Terminal Arrival Routes)

Standard Terminal Arrival Route (STAR) procedures provide structured routing from the enroute environment to the airport terminal area. Each STAR consists of waypoints defining the arrival path.

Runway Designations

Standard Format

• Specific Runway: 30, 36, 27L - Applies to single runway
• All Runways: ALL - Applies to all runways
• Grouped Runways: 36B - Applies to 36L/36C/36R

Special Cases

Route Segment Starting Point Definition

Each STR procedure must define the route segment starting point in the first line

Example:

STR ZGSZALL  322166098018BEKOLBEK1XA      +22543333+1141333330
STR ZGSZ15   322167098018BEKOLBEK1XA      +22543333+1141333330
STR ZGSZ15   322168259574CEN45BEK1XA      +22691161+1140501530
STR ZGSZ16   322169098018BEKOLBEK1XA      +22543333+1141333330
STR ZGSZ16   322170259574CEN45BEK1XA      +22691161+1140501530

BEKOL indicates the starting point of this arrival procedure

Different Runway Segments

If the same arrival procedure corresponds to multiple runways, all segments need to be listed separately according to runway designation

Example:

STR ZBAAALL  320182097915OSUBAOSUB7X      +40736389+1170372221
STR ZBAAALL  320183258281AA169OSUB7X      +40680611+1169732221

Data Integration

STAR procedures connect to other navdata sections:

• Airways: Entry points from enroute structure
• Waypoints: Navigation points in STAR routes
• Runways: Destination runways for arrivals

Next Steps

• Review SID procedures - Departure procedure complement
• Understand waypoints - STAR navigation points
• Use analysis tools - Extract and analyze STAR data
