P.S. - Also on air radar warning crash dives dives I only maintain flank until I'm at a depth I'm comfortable with. Then I drop it to 1 knot, wait two hours. Then, come to periscope depth, check sonar, come to radar depth, check radar, and only then do I surface and come back to my standard 10 knots. Less battery used underwater =less charging time on the surface.
