It's good to see that I'm using the right tactics on patrol! LOL.
i.e.
Dive for all aircraft contacts, except as specifically directed by previous instructions of the commanding officer.
Turn away from all fishing vessels or small craft unless ordered by the commanding officer to attack.
In making periscope observations, first sweep the horizon and sky in low power for aircraft or close surface craft. Follow this, if all clear, by a slow deliberate search in high power, not exposing the periscope for more than 15 seconds. Develop the habit of obtaining a complete picture of the weather during your observation. Have the quartermaster note the keel depth during the observation and also tell you when 15 seconds of periscope exposure has occurred.
Good info, thanks.
