U.S. IFR/VFR Low Altitude Planning Chart is designed for preflight and enroute flight planning for IFR/VFR flights. The chart is printed front-East, back-West, with insets for the east coast from Washington, D.C. to Boston and on the west coast, the Los Angeles/San Diego area. Information includes the depiction of low altitude LF/MF and VHF airways and mileages, navigational facilities, airports, special use airspace areas, cities, time zones, major drainage, a directory of airports with their airspace classification and a mileage table showing great circle distances between major airports. Revised annually.

IFR Enroute Low Altitude Charts provide aeronautical information for navigation under instruments flight rules below 18,000 feet MSL.  Charts are revised every 56 days.

IFR Enroute High Altitude Charts Conterminous U.S. provide aeronautical information for navigation under instruments flight rules at or above 18,000 feet MSL. Charts are revised every 56 days.

The IFR High Altitude Charts include:

Jet route structure
RNAV Routes
VHR radio aids to navigation (frequency, identification, channel, geographic coordinates)
Airports that have an Instrument Approach Procedure or a minimum 5000′ hard surface runway
Airway distances
Reporting points and GPS/RNAV Waypoints
Special Use Airspace Areas

The IFR Enroute High Altitude Charts are at a scale of 1 inch = 20 nm. Unfolded charts are 55 x 20 inches and folded to 5 x 10 inches.
