Introduction and background l.jpg

INTRODUCTION AND BACKGROUND

  • MOST LIGHTED AIDS TO NAVIGATION ARE EQUIPPED WITH A DAYLIGHT CONTROL

    • AUTOMATICALLY CAUSES THE LIGHT TO OPERATE (ON) DURING DARKNESS AND BE OFF DURING DAYLIGHT

  • EACH LIGHT IS UNDER ITS OWN CONTROL

    • THEREFORE ALL LIGHTS DO NOT COME ON OR GO OFF AT THE SAME TIME

  • AID VERIFIERS MUST ASSURE THERE IS SUFFICIENT DARKNESS TO WHERE A LIGHT SHOULD BE OPERATING

    • BEFORE REPORTING THE LIGHT AS "EXTINGUISHED"


Describing a light s characteristics l.jpg

DESCRIBING A LIGHT'S CHARACTERISTICS

  • LIGHTRHYTHM

    • LIGHTED AIDS TO NAVIGATION ARE : "FIXED" (CONTINUOUSLY ON), "FLASHING“, ”OCCULTING“, “ISOPHASE“, ETC. (SEE NEXT CHART)

  • LIGHT PERIOD

    • FOR OTHER THAN "FIXED" LIGHTS, THE TIME IN SECONDS DURING WHICH THE PATTERN OF FLASHES IS REGULARLY REPEATED

  • LIGHT (LENS) COLOR

    • RED AND GREEN (HAVE LATERAL SIGNIFICANCE)

    • WHITE AND YELLOW (HAVE NO LATERAL SIGNIFICANCE


Slide6 l.jpg

FOR EXAMPLE:

A LIGHT WITH PUBLISHED CHARACTERISTICS OF

"Fl G 6s"

WOULD HAVE A FLASHING LIGHT RHYTHM,

GREEN LENS COLOR,

ONE FLASH PER PERIOD,

AND A PERIOD OF SIX SECONDS

DESCRIBING A LIGHT'S CHARACTERISTICS

IF A LIGHT HAS PUBLISHED CHARACTERISTICS OF:

Fl (2) R 6s

WHAT IS THAT LIGHT'S:

  • LIGHT RHYTHM___________________________

  • LIGHT PERIOD ____________________________

  • LIGHT (LENS) COLOR _____________________


Verifying a light s characteristics l.jpg

VERIFYING A LIGHT'S CHARACTERISTICS

  • AIDS WITH FIXED CHARACTERISTICS

    • ARE CONTINUOUSLY "ON" AND ARE SHOWN IN THE LIGHT LIST WITH CHARACTERISTICS OF "F R" (FIXED RED), "F G" (FIXED GREEN) OR "F W" (FIXED WHITE)

    • SHOULD BE VERIFIED TO ASSURE THAT:

      • LIGHT IS IN FOCUS UPSTREAM AND DOWNSTREAM -- LAMP FIXTURE IS NOT LEANING MORE THAN 15 DEGREES, NOT COMPROMISED BY BRUSH OR TREES

      • LAMP IS IN GOOD SHAPE -- NOT EXTINGUISHED OR DIM, NOT COMPROMISED BY BIRD NESTS OR FOULING


Verifying a light s characteristics10 l.jpg

VERIFYING A LIGHT'S CHARACTERISTICS

NOTE:

  • MANY PRIVATE AIDS ARE SHORE POWERED (VS BATTERY POWERED) AND MAY NOT USE A DAYLIGHT CONTROL TO TURN THE LIGHT OFF DURING DAYLIGHT HOURS.

  • THE LIGHT MAY BE "ON" 24 HOURS A DAY. THIS IS NOT A DISCREPANCY.

  • AIDS WITH FLASHING CHARACTERISTICS

    • IN ADDITION TO THE ABOVE VERIFICATIONS, MUST ALSO BE TIMED TO VERIFY THAT THE CHARACTERISTICS ARE AS PUBLISHED IN THE LIGHT LIST.


Verifying a light s characteristics11 l.jpg

VERIFYING A LIGHT'S CHARACTERISTICS

  • VERIFICATION OF A LIGHT'S CHARACTERISTICS REQUIRES TIMING EACH LIGHT FOR THE NUMBER OF FLASHES EXPECTED IN ONE MINUTE

  • NOTE:

    • FEDERAL RDB AIDS HAVE FOUR SECOND PERIODS. LDB AIDS HAVE FIVE SECONDS

    • FEDERAL WHITE AIDS MAY BE SEEN

    • MOST PAToNS HAVE SIX SECOND PERIODS

    • MOST RED AIDS HAVE TWO FLASHES PER PERIOD

    • MOST GREEN AIDS HAVE ONE FLASH PER PERIOD

Verifying a light s characteristics13 l.jpg

VERIFYING A LIGHT'S CHARACTERISTICS

  • DETERMINING THE "PERIOD" AND THE NUMBER OF FLASHES PER PERIOD FROM THE CHARACTERISTICS PUBLISHED IN THE LIGHT LIST

    Fl(2) R 6s

    • EXAMPLE: IF THE PUBLISHED CHARACTERISTICS ARE SHOWN AS " Fl (2) R 6s"

    • THE PERIOD IS SIX SECONDS AND THE NUMBER OF FLASHES PER PERIOD IS TWO.


Verifying a light s characteristics14 l.jpg

VERIFYING A LIGHT'S CHARACTERISTICS

  • DETERMINING THE NUMBER OF PERIODS PER MINUTE BY DIVIDING SIXTY SECONDS BY THE PERIOD

    • EXAMPLE: A LIGHT WITH A PERIOD OF SIX SECONDS WILL HAVE TEN PERIODS PER MINUTE (60 DIVIDED BY 6)

    • EXAMPLE: A LIGHT WITH A PERIOD OF FOUR SECONDS WILL HAVE FIFTEEN PERIODS PER MINUTE ( 60 DIVIDED BY 4)


Verifying a light s characteristics15 l.jpg

VERIFYING A LIGHT'S CHARACTERISTICS

  • MULTIPLYING THE NUMBER OF PERIODS PER MINUTE BY THE NUMBER OF FLASHES PER PERIOD

    • EXAMPLE: (TEN PERIODS PER MINUTE) X (TWO FLASHES PER PERIOD) EQUALSTWENTY FLASHES PER MINUTE .

    • EXAMPLE: (TEN PERIODS PER MINUTE) X (ONE FLASH PER PERIOD) EQUALS TEN FLASHES PER MINUTE

    • EXAMPLE: (FIFTEEN PERIODS PER MINUTE) X (TWO FLASHES PER PERIOD) EQUALSTHIRTY FLASHES PER MINUTE

Techniques for timing lights l.jpg

TECHNIQUES FOR TIMING LIGHTS

  • EVERY AID VERIFIER WILL DEVELOP THEIR OWN "STYLE" FOR TIMING LIGHTS.

  • THE FOLLOWING IS SUGGESTED ONLY AS A STARTING POINT FOR AUXILIARISTS NEW TO AID VERIFICATION.

  • EXPERIENCE HAS DETERMINED THAT A “SPORTS” WATCH

    • MAY BE EASIER TO USE WITH ITS LARGE BUTTONS AND DISPLAY

    • USUALLY INEXPENSIVE, AVAILABLE AT K-MART, WAL-MART, RADIO SHACK, ETC.

    • AN ILLUMINATED DISPLAY IS CONVENIENT

  • .


Techniques l.jpg

TECHNIQUES

  • ACTUAL TIMING:

    • MUST BE PERFORMED AT NIGHT

    • SHOULD START AND STOP AT THE END OF THE LAST FLASH IN A PERIOD TO ELIMINATE 'ANTICIPATION“

    • MUST BE PERFORMED AS A DEDICATED TASK, UNINTERRUPTED, BY AN INDIVIDUAL WITH NO OTHER ASSIGNED TASKS

Safety considerations l.jpg

SAFETY CONSIDERATIONS

  • MAINTAIN ADEQUATE LOOKOUTS!

  • PRE-PLANNING IS CRITICAL

    • KNOW WHAT IS BEING SOUGHT AHEAD OF TIME

  • AV TEAM SEPARATE FROM OPS TEAM (CREW)

  • OPS TEAM FOCUSES ON SAFETY

  • AV TEAM OF TWO WORKS WELL

    • SHARING OF TASKS:

      • READING CHARTS

      • ENTERING DATA

      • TIMING

      • OBSERVING/COUNTING FLASHES

      • PORTABLE CASSETTE RECORDER CAN BE USEFUL


Checking a light s focus l.jpg

CHECKING A LIGHT’S FOCUS

  • IN ORDER FOR A LIGHT TO BE CONSIDERED "WATCHING PROPERLY"

    • IT MUST BE LEVEL SO AS TO BE VISIBLE WITHIN THE VIEWING RANGE OF THE MARINER

  • TOWER MOUNTINGS, AND A LEVELING PLATE THAT ATTACHES THE LIGHT ASSEMBLY TO A TOWER OR OTHER STRUCTURE, ALLOW THE LIGHT'S HORIZONTAL POSITION TO BE ADJUSTED TO AN ACCEPTABLE "LEVEL" POSITION

    • WHICH IS DEFINED AS +/- 15 DEGREES FROM THE HORIZONTAL


Checking a light s focus27 l.jpg

CHECKING A LIGHT’S FOCUS

  • AID VERIFIER NEEDS TO CHECK IF FIXTURE IS LISTING OVER 15 DEGREES :

    • "IS THE LIGHT IN FOCUS AND/OR ARE ANY DAYBOARDS LEANING MORE THAN 15 DEGREES"?

  • STRUCTURES (PILINGS, CELLS, CONCRETE PIERS, ETC.) MAY OFTEN BE LISTING AS MUCH AS 35 TO 40 DEGREES WHICH CANNOT BE FIXED WITHOUT TOTALLY REBUILDING THE AID

    • HOWEVER, THE LIGHT MAY BE "IN FOCUS" (AND "WATCHING PROPERLY") BY USING THE LEVELING PLATE OR BY ADJUSTING THE MOUNTING HARDWARE.


Checking a light s focus28 l.jpg

CHECKING A LIGHT’S FOCUS

  • NOTES:

  • AIDS ARE MADE TO VIEWED FROM TOWBOAT PILOT HOUSES, NOT RECREATIONAL BOATS

  • WHAT MIGHT SEEM “OUT OF FOCUS” TO AN OPFAC MIGHT BE “WATCHING PROPERLY” TO COMMERCIAL TRAFFIC

  • OFTEN THE DAYBOARDS ARE ANGLED FOR BETTER VISIBILITY WHEN THE AID IS HIGH ON THE BANK. THIS NOT A DISCREPANCY

  • WHILE CHECKING FOR FOCUS (USE BINOCULARS) LOOK AT THE BATTERY CASE AND THE SOLAR PANEL FOR VANDALISM OR THEFT


When is a light considered to be watching properly l.jpg

WHEN IS A LIGHT CONSIDERED TO BE "WATCHING PROPERLY"

  • LIGHT IS IN PROPER FOCUS AND CAN BE SEEN UNOBSTRUCTED IN THE DIRECTION(S) AND FOR THE RANGE EXPECTED

  • FLASHING LIGHTS ARE CONSIDERED TO BE "WATCHING PROPERLY" IF THE ACTUAL (TIMED) NUMBER OF SECONDS IS WITHIN PLUS OR MINUS FIVE PERCENT (5%).

    • EXAMPLE: A Fl G 6s LIGHT FLASHES 10 TIMES A MINUTE. 5% OF 20 EQUALS ONE (1). THE LIGHT MAY FLASH 9, 10, OR 11 TIMES IN 60 SECONDS AND STILL BE “WATCHING PROPERLY.” ANY OTHER NUMBER IS “DISCREPANT.”


Reporting paton verifications l.jpg

REPORTING PAToN VERIFICATIONS

  • IF YOU NEED TO IDENTIFY A SPECIFIC LIGHT FOR PRIVATE AIDS WITH MORE THAN ONE LIGHT

    • BEGIN WITH THE MOST U/S LIGHT AS #1 AND:

    • 2U/S, D/S

    • 3U/S, MIDDLE, D/S

    • 4MOST U/S, U/S, D/S, MOST D/S

    • 5MOST U/S, U/S, MIDDLE, D/S, MOST D/S

Nomenclature for Light Identification /Location


Reporting paton verifications31 l.jpg

REPORTING PAToN VERIFICATIONS

  • PAToN verifications are to be reported on the D8 Excel spreadsheet or in any manner that sends the required information.

  • Discrepancies should be described completely in the “Remarks” column.

  • Communications between the CG and the aid owner are more productive when information is complete and accurate.

  • REMEMBER! Extinguished lights are considered “Critical” and need to be reported to GOHV ASAP


Reporting the results summary l.jpg

REPORTING THE RESULTSSUMMARY

  • Accurate and thorough reporting required

    • Coast Guard personnel receiving our reports are expected to take action based on the data reported

    • Action may involve contacting owner or bridge to get discrepancies corrected

    • Be very specific in describing discrepancies and the location (for example, which light) of each discrepancy

    • NOTHING LESS THAN 100 PERCENT COMPLETE, DEFECT-FREE REPORTS ARE ACCEPTABLE
