VFR Terminal Area Charts
Terminal Area Charts (TAC) depicts the airspace designated as Class B airspace.
These charts are similar to sectional charts but have more detail because the chart
scale is larger. TACs are intended for pilots operating from airfields within or near Class
B and C airspace. TACs are revised semiannually except that Puerto Rico and Virgin
Island charts are revised annually.
U.S. IFR/VFR Low-Altitude Planning Chart
The IFR/VFR Low-Altitude Planning Chart is designed for preflight and enroute flight
planning for IFR and VFR flights. This chart depicts low altitude airways and mileage,
NAVAIDs, airports, special use airspace, cities, time zones, major drainage, a directory
of airports with their airspace classification, and a mileage table showing great circle
distances between major airports. Planning charts are revised annually.
Terminal Procedures Publication
Terminal Procedures Publication (TPP) is published in 26 volumes covering the
conterminous United States, Puerto Rico, and the Virgin Islands. TPPs include:
Instrument Approach Procedure (IAP) charts
Departure Procedure (DP) charts
Standard Terminal Arrival (STAR) charts
Airport diagrams
The ―d-TPP‖ is the same data as the TPP only in digital format. TPPs are updated every
28 days.
Digital Aeronautical Chart Supplement
The Digital Aeronautical Chart Supplement (DACS) is designed to provide digital
airspace data not otherwise readily available for flight planning purposes only and
should not be used as a substitute for a chart. DACS are produced every 56 days,
coinciding with the airspace cycle and includes a change notice at the midpoint between
revisions. The DACS has nine sections:
Section 1: High altitude airways, conterminous U.S.
Section 2: Low altitude airways, conterminous U.S.
Section 3: Selected instrument approach procedure, NAVAID, and fix data
(includes 28 day change notice)
Section 4: Military training routes
Section 5: Alaska, Hawaii, Puerto Rico, Bahamas, and selected oceanic routes
Section 6: Standard terminal arrivals (STAR) and profile descent procedures
Section 7: Departure Procedures (DP)
