And the 30 hour student learned that when?
That would depend on the student and the instructor and how far that 30 hrs has taken the student. Lame student, lame instructor, they don't know what an FAF is or an SAP. A dedicated student regardless the instructor has found that tidbit in his own reading of everything available. A good instructor has probably introduced it around the second cross country when they introduced radio navigation to the picture (first X/C should be straight pilotage) and introduced the student to a SAP as a navigational aid to help guide him to an airport runway when visual means are down yet still M/VFR. There is no prohibition from flying instrument proceedures as a VFR pilot. You should know at least 3 ways to do nearly anything you have to do, and finding an airport is one of them.
