A IPC is valid for 6 months. You need to read legal documents using formal
rules.

Nothing in the FARs says anything about a validity period (6 months or
otherwise) for an IPC. There is a 6-month validity period for the 6
approaches (and holds and tracking).

The IPC rule says that a pilot who does not meet the 6-6 rule may take an
IPC,

Yes.

the IPC becomes mandatory 12 months after the date currency was
established.

That's a confusing way to put it, since currency may have been established
years ago, and maintained ever since. The IPC becomes mandatory six months
after currency has expired.

But that's not the question at issue. We all agree when the IPC is required.
We all agree that an IPC might include only 3 approaches. The question is
whether, *in addition* to the IPC (when the IPC is required), you have to
satisfy the 6-in-6 requirement of 61.57c in order to be instrument current.
My point is that nothing in 61.57c (or in 61.57d) asserts that the 6-in-6
requirement is waived by the completion of an IPC. As the regs are written
(though perhaps not as they're interpreted in practice), the 6-in-6
requirement has to be met even if you've just had an IPC.

You carefully snipped the quoted regulation so it couldn't be seen by
anyone else.

Uh, sure Jim. No one here is familiar with 61.57d, or knows how to find it
unless we keep repeating it in each of our posts.

The check is available at any time

Yes.

and fully meets the requirements of legal currency...

No. That's exactly what the regs *don't* say. If you disagree, please
explain what part of 61.57c or 61.57d (or any other FAR) supports your claim
that an IPC by itself suffices to reestablish currency.

What 61.57d says is that if your instrument currency expired six months ago,
then you're *not* instrument-current again *unless* you pass an IPC. Nowhere
does it say that you *are* current if you *do* pass an IPC but *do not* meet
the *other* instrument-currency requirements (such as the 6-in-6 rule in
61.57c).

You need to read legal documents using formal rules.
If you don't "see" the meaning of the words, suggest you find a
qualified high school English teacher

Good advice. Please heed it yourself. In the meantime, the relevant formal
principle is that "not-P unless Q" is equivalent to "not-Q implies not-P",
but is *not* equivalent to "Q implies P". But the latter is how you're
(incorrectly) interpreting it. (Here, P is "instrument-current again after
currency lapsed for at least six months" and Q is "passed an IPC".)
