Never would have thought of this, but it seems plausible enough, now
that you mention it.

Although there is a regulation that says that the pilot is required to
use a prescribed "instrument letdown" when cleared for an approach,
or something like that.

I wonder, would this be a violation of that?


No. That regulation begins with "Unless otherwise authorized by the
Administrator", and FAR Part 1 defines "Administrator" as "the Federal
Aviation Administrator or any person to whom he has delegated his authority
in the matter concerned."
