This is especially true of how the feds treat SIDs and STARs. Consider, for example, the elaborate time en route problems involving standard instrument departures. In fact, apart from the test writers in Oklahoma City, maybe no one ever has done such calculations. Even though it's misdirected, the emphasis on SIDs and STARs is not misplaced. Jeppesen bundles them together with the approaches.
NOS groups the arrivals at the front of the booklets while the SIDs are paired with the approaches.
Personally I like the way the STARs appear, since it saves duplication. I didn't check carefully, but I saw the Regional Six departure printed on 10 different pages in the same NOS booklet. Jeppesen does the same, of course, meaning you might get to file one SID 10 times. Even though we consider them instrument procedures for pilots to use, SIDs and STARs aren't there primarily to make the pilot's life easier. The point is, SIDs and STARs allow ATC to codify commonly used clearances and procedures.
