bac, Ore are effective diving planes and rudder ordered angles 
Spe» Sse are ordered angles to port and starboard shafts 
5p , 5 are actual angles of port and starboard shafts 
64, or are effective diving plane and rudder angles which 
would produce forces and moments equivalent to 
deflection angles of stocks
