b. Charts will be reviewed, signed, and dated, prior to initial use. All 
subsequent changes will be addressed in the Navigation brief. At a minimum, 
the following information will appear on every paper chart displaying a 
restricted water track:
Prepared by:
Reviewed by: (Senior QM/ANAV)
Submitted by: (NAV) __________ Approved by: (00) Date:
4. Requirements While in Restricted Waters
a. Navigation information maintained in CIC/CDC/TOP, designated as the 
secondary navigation plot will supplement the Navigators plot. The CO may 
authorize a shift in the location of the primary plot to suit a particular 
situation.
b. The Navigator will ensure:
(1) Turn points are calculated based upon the ship's advance and transfer 
tables, and turn bearings/ranges and slide bars are plotted at each point. 
Recommendations for course changes should consider set and drift. The slide 
bar will be used to compute a revised turn bearing/range if the ship is right 
or left of track when approaching the turn.
c. The Navigation Evaluator will ensure every fix determined from the primary 
navigation plot (Bridge) is compared to the fix obtained at the secondary 
plot (CIC/CDC/TOP). Every verbal position report made by the Navigation 
Evaluator to the Navigator, Conning Officer, and CO will include the 
following information for each fix:
(1) Fix time.
(2) Fix/EP Quality (excellent, good, poor, etc.) as determined by the 
Navigation Evaluator based on CO's guidance. For GPS fixes, the CO may assign 
fix quality based on Figure of Merit to Estimated Position Error or request 
that GPS fixes be identified with Figure of Merit (see Appendix H).
(3) Fix method (NAVSSI Block 4 blended position, GPS, visual, RADAR, running fix, etc.)
