It's In The Presentation
Pilots read the notes and take them as gospel. But as approaches get more complex, summing it up in a few words can mean summing it up wrong.
Regard the Jeppesen version of the RNAV (GPS) Rwy 19 approach to Meridian, MS (KMEI). This chart shows the simplest TAA you can have. The limit for a turn based on GPS is 90 degrees, so the maximum allowable turn from a route direct to the IAF to the leg after crossing the IAF is 90 degrees. This means each TAA should contain at least two sectors, divided by courses 90 degrees off the inbound course.
