Holy smokes... All the information we need to not have to guess about this stuff is public. See the link below:
CNATRA Instructions
These are all clearly defined in the CNATRAINST 1542 series. Primary MPTS is 1542.140C. Adv Helo MPTS is 1542.156A. They're all clearly labeled, and all the information as to course flow, the "attrition flowchart," and the means by which one might be attrited is in plain english.
By the way, IPC means "Initial Progress Check."
edit: Mr. Boyd beat me to it.
