Sectional Terminal Area and WAC

Previous Chapter Navigational Charts -- Table of Contents -- Standard Instrument Departure (SID) Next Chapter

The sectional, Terminal Area and WAC charts are described in the AIM at section 9-1-4. These charts are used mainly for VFR navigation and have only limited application in simulated flying when using the SB/PC system. They are handy for general flying and to familiarize yourself with an area.
The WAC presents the same basic information as a sectional chart, but, at a larger scale and not with as great a detail.
The VFR Terminal Area Charts are a smaller scale than the sectionals and are useful for becoming familiar with the area around major airports.

While these three types of charts are not sufficient for IFR flight, they can be used for general flight planning and obtaining frequencies of navaids if you do not have the appropriate IFR charts handy.
There is, however,  key information necessary for safe IFR flights that is not included on these charts, such as MEAs (Minimum Enroute Altitudes) and MRAs (Minimum Reception Altitude). The former assures obstacle clearance and the latter assures navaid reception.
