Default OLV GPS 36 approach question

Not so with this past February's AIM and ATC procedure change:

You informed me of this change a month or two ago, but that doesn't
change the fact that published altitudes apply after arriving at the
IF. An assigned altitutde below an intermediate segment altitude would
be an error, as I think you'd agree.


I would agree, and if there were a step-down altitude in the
intermediate higher than 2,100, then the assignment would have been in
error.

But, in the circstances with this IAP, it was functionally no different
than "vectors to final" (i.e., the intermediate segment), which wouldn't
be any surprise to have done at 2,100 feet.

Having said that, because of the nuance of this new procedure, an
assignment to cross DOCAP at 2,800 would be better human-factors.

However, as I reviewed the original post, he said he was cleared to
DOCAP. In my mind, I pictured the right base entry, which is the one
that I usually make, but DOCAP is the IF/IAF and which makes it a
straight-in. The first published altitude IS (I think) 2,100, so the
controller didn't make an error after all. The 2,800 that the OP
mentioned was probably the straight in sector altitude, which becomes
irrelevant when cleared to the IF.
