What Vacchiano taught was this:

Get a C trumpet part with the key signature of D major (2#'s)

Get a piccolo and set it to A.

If you have that combination you pretend the part is in bass clef. So, written D becomes F, E becomes G and so on. Here's the important part: add three flats to the key signature and do some math. Three flats plus two sharps equals...? Right, one flat (F major)

So, a C part with a piccolo in A means read bass clef and add three flats.
