Defining the terminal arrival area settings (Aviation)

The Terminal Arrival Area (TAA) element appears in the plan view of an instrument approach procedure (IAP) and provides safe altitude and distance information. TAAs are found only on RNAV approaches. The element contains three parts that reflect the straight-in, right-base, and left-base areas for the approach. Each part can contain one or more designated points, an altitude label, and designated point identification labels.

The default style of new TAA elements is determined by the settings on the Terminal Arrival Area dialog box. Changing the settings does not alter existing TAA elements. Existing TAA elements can be updated by clicking the Terminal Arrival Area tool, which will regenerate the element based on updates to the data and/or settings.

You can preview changes to any settings on the Terminal Arrival Area dialog box, which allows you to see how the element is going to look on the chart layout before they are applied. The settings are divided into groups based on the part of the element they affect. The Sector group contains properties that affect the appearance of the different parts that comprise the TAA. The Waypoint group contains properties that affect the waypoint symbols and text. The Distance group contains properties that affect the appearance of the distance text outside of the different parts of the TAA.
