You can't extend only one bow plane. Both have to come out. Not sure why the instructions make a big deal of the selection. Having only one would fail the other one (on an American boat). Not sure what German practices would be, but being that we copied them, I'd say they were fitted the same. If only one was out, it would affect the sub much like a plane that lost one wing.

Cheers,
