An emergency is not limited to the
aircraft having a mechanical or similar such problem. Violating Class B
airspace has unknown ramifactions, such as perhaps approach control seeing
the
intrustion and declaring an emergency on your flight because of loss of
separation, etc., etc.

It's true that a controller *might*, for additional reasons, deem a Class B
incursion to be an emergency. But I doubt that a slight breach of Class B,
with good visibility and no conflicting traffic, would *by itself*
constitute an emergency. So I don't think 91.3b would necessarily come into
play.

Again, I don't dispute that you should avoid the incursion, even if you have
to violate 91.123b. I just wish the FARs weren't contradictory on that
point.
