So which ones right then? Should I be able to do 0 knots at 220m without my pumps running or do i have to have enough revolutions with silent running to maintain my depth and therefore make some noise either way. Ive just done my usual start of patrol depth test to 225m after leaving Thalia (24/21940)and went to All Stop. Didnt sink even on TCx8.
So will I start to sink if I rigged for silent running because of no pumps....?
What are the symbols that appear when you are rfsr? One is no reloading but the other 3?
Its all a learning curve....

Cheers for helping me out chaps?
