AIM 8/15/19  3. U.S. Terminal Procedures Publication (TPP). TPPs are published in 24 loose − leaf or perfect bound volumes covering the conterminous U.S., Puerto Rico and the Virgin Islands. A Change Notice is published at the midpoint between revisions in bound volume format and is available on the internet for free download at the AIS website. (See FIG 9 − 1 − 15.) The TPPs include: (a) Instrument Approach Procedure (IAP) Charts. IAP charts portray the aeronautical data that is required to execute instrument approaches to airports. Each chart depicts the IAP, all related navigation data, communications information, and an airport sketch. Each procedure is designated for use with a specific electronic navigational aid, such as ILS, VOR, NDB, RNAV, etc. (b) Instrument Departure Procedure (DP) Charts. DP charts are designed to expedite clearance delivery and to facilitate transition between takeoff and en route operations. They furnish pilots’ departure routing clearance information in graphic and textual form. (c) Standard Terminal Arrival (STAR) Charts. STAR charts are designed to expedite ATC arrival procedures and to facilitate transition between en route and instrument approach operations. They depict preplanned IFR ATC arrival procedures in graphic and textual form. Each STAR procedure is presented as a separate chart and may serve either a single airport or more than one airport in a given geographic area. (d) Airport Diagrams. Full page airport diagrams are designed to assist in the movement of ground traffic at locations with complex runway/taxi- way configurations and provide information for updating geodetic position navigational systems aboard aircraft. Airport diagrams are available for free download at the AIS website. 4. Alaska Terminal Procedures Publication. This publication contains all terminal flight proce- dures for civil and military aviation in Alaska. Included are IAP charts, DP charts, STAR charts, airport diagrams, radar minimums, and supplemen- tary support data such as IFR alternate minimums, take − off minimums, rate of descent tables, rate of climb tables and inoperative components tables. Volume is 5 − 3/8 x 8 − 1/4 inch top bound. Publication revised every 56 days with provisions for a Terminal Change Notice, as required. c. Planning Charts. 1. U.S. IFR/VFR Low Altitude Planning Chart.  This chart is designed for prefight and en route flight planning for IFR/VFR flights. Depiction includes low altitude airways and mileage, NAVAIDs, airports, special use airspace, cities, times zones, major drainage, a directory of airports with their airspace classification, and a mileage table showing great circle distances between major airports. Scale 1 inch = 47nm/1:3,400,000. Chart revised annually, and is available either folded or unfolded for wall mounting. (See FIG 9 − 1 − 10.) 2. Gulf of Mexico and Caribbean Planning Chart. This is a VFR planning chart on the reverse side of the  Puerto Rico  − Virgin Islands VFR Terminal Area Chart.  Information shown includes mileage between airports of entry, a selection of special use airspace and a directory of airports with their available services. Scale 1 inch = 85nm/1:6,192,178. 60 x 20 inches folded to 5 x 10 inches. Chart revised annually. (See FIG 9 − 1 − 10.) 3. Alaska VFR Wall Planning Chart.  This chart is designed for VFR preflight planning and chart selection. It includes aeronautical and topo- graphic information of the state of Alaska. The aeronautical information includes public and military airports; radio aids to navigation; and Class B, Class C, TRSA and special − use airspace. The topographic information includes city tint, populated places, principal roads, and shaded relief. Scale 1 inch = 27.4 nm/1:2,000,000. The one sided chart is 58.5 x 40.75 inches and is designed for wall mounting. Chart is revised biennially. (See FIG 9 − 1 − 9.) Types of Charts Available 9 − 1 − 7
