Navigation draft, definition of shoal water and the method to indicate shoal water for each navigation system as well as on paper charts, command definitions of navigation zones, fix intervals for each zone, interval for primary positioning source must be compared to an unrelated positioning source and logged, standard plotting symbols, alarm management, line handling commands, method used to indicate approved track lines, guidance on electronic chart displays including filters and scaling, guidance on cutter small boat navigation while away from the cutter, nav team manning requirements, helm commands, special sea detail, anchoring and mooring bill, list of paper charts required to be on board with which ones shall be kept up to date, ships characteristics, electronic chart data hierarchy, when to determine gyro error, AIS settings and usage, Electronic casualty control procedures, when navigation with autopilot ships controls must be logged as well as propulsion, GPS offsets during evolutions, drag and swing circle procedures, heading and speed input from radar, cross track warning and alarm settings for each navigation zone

Question 6

What can be used to indicate shoal water for each navigation system as well as on paper charts?

Answer 6

• Safety depth
• Safety contour
• Depth below the keel

Question 7

What is the interval for comparing your primary position source to a unrelated positioning source?

Answer 7

Shall be conducted every third fix in restricted waters in other waters it shall be conducted once a day

Question 8

Where do you find the standard navigation plotting symbols?

Answer 8

Enclosure 1 of the Commandant’s Navigation Standards Manual

Question 9

What is Alarm Management?

Answer 9

It states when alarms may be silenced or disabled

Question 10

Where do you find your standard line handling commands?

Answer 10

Enclosure 2 of the Commandant’s Navigation Standards Manual

Question 11

What are the only GPS corrections currently authorized?

Answer 11

The only GPS corrections currently authorized for CG coastal and restricted water navigation use are provided by the differential GPS system and the Wide Area Augment System (WAAS)

Question 12

What is WAAS?

Answer 12

It is a satellite based GPS augmentation system being implemented by the FAA. WAAS is not authorized for ATON positioning

Question 13

When shall you compare positioning sources while underway?

Answer 13

Shall be once a day in open ocean and every third fix in restricted waters

Question 14

What constitutes CAT I navigation?

Answer 14

• GPS with DGPS corrections or WAAS enabled
• GPS PPS (precise positioning source)
• GPS SPS (standard positioning source) with selective availability set to zero
• Visual and/or radar (includes radar or chart matching)

Question 15

What constitutes CAT II navigation?

Answer 15

• Inertial navigation system

- Celestial

Question 16

When does GPS SPS become a CAT II navigation source?

Answer 16

When international and SA is being used, its not adequate for navigation in harbor, harbor approach, near coastal and other restricted waters

Question 17

What can you do if while underway, the fix quality comes into question while operating in restricted waters?

Answer 17

• reduce speed as appropriate
• take all the way off
• increase the fix frequency
• turning away from danger

Question 18

What constitutes an electronic fix?

Answer 18

When displayed on a chart from an adequate positioning source including radar or chart matching capabities

Question 19

What constitutes a fix on a paper chart?

Answer 19

The intersection of LOP’s from at least 3 prominent points of land, fixed and/or celestial objects with a separation of 15 degrees or greater, when using relative bearings with a minimum of 2 LOP’s and 1 radar range, if 3 LOP’s are not available advancing LOP’s to a common time to creat a running fix may be used

Question 20

What can be used to verify fixes?

Answer 20

• soundings
• ATON
• radar or other electronic means
• seamen’s eye

Question 21

When are paper charts considered up to date?

Answer 21

They are considered up to date if they are both the most current edition and corrected up to the latest LNM, WNM, BNM

Question 22

When shall set and drift be determined?

Answer 22

• if the fix interval is 3 minutes or greater, shall be determined at every fix
• if less than 3 minutes, shall be determined every second fix

Question 23

What constitutes an EP?

Answer 23

An estimated position is a DR position modified by additional information which in its self is insufficient to establish a fix
