U.S. Terminal Procedures Publications are published in 24 loose-leaf or perfect bound volumes covering the conterminous U.S., Puerto Rico and the Virgin Islands. Included in the Terminal Procedures Publications are:
- Instrument Approach Procedure (IAP) Charts
- Departure Procedure (DP) Charts
- Standard Terminal Arrival (STAR) Charts
- Charted Visual Flight Procedures (CVFP)
- Take-off, Radar, & Alternate Minimal textual procedures
- Airport Diagrams
- Legend & General Information pages
IAP Charts are designed to provide an IFR descent from the enroute environment to a point where a safe landing can be made. DP Charts are Air Traffic Control (ATC) coded departure procedures which have been established at certain airports to simplify clearance delivery procedures. STAR Charts are ATC-coded IFR arrival routes established for certain airports to simplify clearance delivery procedures. CVFPs are an operational technique designed to move air traffic safely and expeditiously. In addition to conventional visual approach procedures, it has been necessary to specify routes/altitudes to enhance noise abatement at some locations. CVFPs have been developed to provide a pictorial display of these visual arrival routes. Airport Diagrams are specifically designed to assist in the movement of ground traffic at locations with complex runway/taxiway configurations and provide information for updating geodetic position navigational systems aboard aircraft. Airport Diagrams can also be found in back of the Airport/Facility Directory.
Volumes are 5-3/8 x 8-1/4 inch, perfect-bound, or loose-leaf format. Loose-leaf volumes are shrink wrapped with four holes punched at the top. The volumes are revised every 56 days. A Change Notice is published at the midpoint between revision in bound volume format.
