  3. INTRODUCTION AND BACKGROUND EIGHTH WESTERN RIVERS REGION -- AID VERIFIER TRAINING VERIFYING A LIGHT'S CHARACTERISTICS • MOST LIGHTED AIDS TO NAVIGATION ARE EQUIPPED WITH A DAYLIGHT CONTROL • WHICH AUTOMATICALLY CAUSES THE LIGHT TO OPERATE (ON) DURING DARKNESS AND TO 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" (DEFECTIVE) Version 2.1

  4. DESCRIBING A LIGHT'S CHARACTERISTICS EIGHTH WESTERN RIVERS REGION -- AID VERIFIER TRAINING VERIFYING A LIGHT'S CHARACTERISTICS THREE FACTORS ARE USED TO DESCRIBE A LIGHT'S CHARACTERISTICS: • LIGHT RHYTHM • LIGHTED AIDS TO NAVIGATION ARE EITHER "FIXED" (CONTINUOUSLY ON) OR GENERALLY EXHIBIT RHYTHMS SUCH AS: "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) 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. Version 2.1

  5. EIGHTH WESTERN RIVERS REGION -- AID VERIFIER TRAININGVERIFYING A LIGHT'S CHARACTERISTICS DESCRIBING A LIGHT'S CHARACTERISTICS TABLE BELOW SHOWS LIGHT RHYTHMS TYPICAL ON THE INLAND RIVERS. Version 2.1

  6. DESCRIBING A LIGHT'S CHARACTERISTICS EIGHTH WESTERN RIVERS REGION -- AID VERIFIER TRAINING VERIFYING 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 ___________________________________ Version 2.1

  7. 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 • 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. EIGHTH WESTERN RIVERS REGION -- AID VERIFIER TRAINING 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. Version 2.1

  8. VERIFYING A LIGHT'S CHARACTERISTICS VERIFICATION OF A LIGHT'S CHARACTERISTICS REQUIRES TIMING EACH LIGHT FOR THE NUMBER OF FLASHES EXPECTED IN ONE MINUTE EIGHTH WESTERN RIVERS REGION -- AID VERIFIER TRAINING VERIFYING A LIGHT'S CHARACTERISTICS NUMBER OF FLASHES EXPECTED IN ONE MINUTE IS CALCULATED BY: • DETERMINING THE "PERIOD" AND THE NUMBER OF FLASHES PER PERIOD FROM THE CHARACTERISTICS PUBLISHED IN THE LIGHT LIST • 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. • 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) • MULTIPLYING THE NUMBER OF PERIODS PER MINUTE BY THE NUMBER OFFLASHES PER PERIOD • EXAMPLE: [[TEN PERIODS PER MINUTE] X [TWO FLASHES PER PERIOD] EQUALS TWENTY FLASHES PER MINUTE . Version 2.1

  9. TIMING A LIGHT EXERCISE: DETERMINE THE NUMBER OF FLASHES EXPECTED IN ONE MINUTE EIGHTH WESTERN RIVERS REGION -- AID VERIFIER TRAINING VERIFYING A LIGHT'S CHARACTERISTICS Fl (2) R 6s DURATION OF EACH PERIOD = _____ SECONDS NUMBER OF FLASHES PER PERIOD = _____ . NUMBER OF PERIODS PER MINUTE = 60 / _____ = _____ NUMBER OF FLASHES PER MINUTE = _____ X _____ = _____ Version 2.1

  10. TIMING A LIGHT EXERCISE: DETERMINE THE NUMBER OF FLASHES EXPECTED IN ONE MINUTE EIGHTH WESTERN RIVERS REGION -- AID VERIFIER TRAINING VERIFYING A LIGHT'S CHARACTERISTICS Fl (2) R 6s DURATION OF EACH PERIOD = __6__ SECONDS NUMBER OF FLASHES PER PERIOD = 2 . NUMBER OF PERIODS PER MINUTE = 60 / 6 = 10 . NUMBER OF FLASHES PER MINUTE = 10 X 2 = 20 . Version 2.1

  11. EIGHTH WESTERN RIVERS REGION -- AID VERIFIER TRAININGVERIFYING A LIGHT'S CHARACTERISTICS TIMING A LIGHT EXERCISE: COMPLETE THE FOLLOWING TABLE FOR THE LIGHT CHARACTERISTICS COMMONLY FOUND ON PRIVATE AND FEDERAL LIGHTED AIDS (THE FIRST ENTRY IS FOR THE EXAMPLE USED ON THE PREVIOUS CHART). Version 2.1

  12. EIGHTH WESTERN RIVERS REGION -- AID VERIFIER TRAININGVERIFYING A LIGHT'S CHARACTERISTICS TIMING A LIGHT EXERCISE: COMPLETE THE FOLLOWING TABLE FOR THE LIGHT CHARACTERISTICS COMMONLY FOUND ON PRIVATE AND FEDERAL LIGHTED AIDS (THE FIRST ENTRY IS FOR THE EXAMPLE USED ON THE PREVIOUS CHART). Version 2.1

  13. TECHNIQUES FOR TIMING A LIGHT 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. EIGHTH WESTERN RIVERS REGION -- AID VERIFIER TRAINING VERIFYING A LIGHT'S CHARACTERISTICS • TIMING A LIGHTED AID REQUIRES A TIMING DEVICE THAT WILL GIVE ELAPSED TIME • MANY WRIST WATCHES HAVE THIS CAPABILITY • HOWEVER, 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. • BUT, USUALLY DOESN'T HAVE ILLUMINATED DISPLAY (REQUIRES NIGHT-VISION PROTECTED LIGHT SOURCE) • 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. Version 2.1

  14. TECHNIQUES FOR TIMING A LIGHT Fl (2) R 6s START STOP EIGHTH WESTERN RIVERS REGION -- AID VERIFIER TRAINING VERIFYING A LIGHT'S CHARACTERISTICS ONE PERIOD ON OFF ,19,20 0, 1, 2, Fl G 6s START STOP ONE PERIOD ON OFF 1, 0, ,10 Version 2.1

  15. CHECKING A LIGHT'S FOCUS • IN ORDER FOR A LIGHT TO BE CONSIDERED AS "WATCHING PROPERLY" • IT MUST BE LEVEL SO AS TO BE VISIBLE WITHIN THE VIEWING RANGE OF THE MARINER • TOWER MOUNTINGS, AND A LEVELING PLATE WHICH 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. • AID VERIFICATION WORKSHEET QUESTION "FIXTURE LISTING OVER 15 DEGREES?" IS REALLY ASKING: • "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. EIGHTH WESTERN RIVERS REGION -- AID VERIFIER TRAINING VERIFYING A LIGHT'S CHARACTERISTICS Version 2.1

  16. WHEN IS A LIGHT CONSIDERED TO BE "WATCHING PROPERLY" EIGHTH WESTERN RIVERS REGION -- AID VERIFIER TRAINING VERIFYING A LIGHT'S CHARACTERISTICS • 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 THREE SECONDS INCLUSIVE (57.0 TO 63.0 SECONDS). • EXAMPLE: IF A LIGHT WITH PUBLISHED CHARACTERISTICS OF: Fl (2) R 6s ACTUALLY SHOWED TWENTY FLASHES IN 58.4 SECONDS, THE LIGHT WOULD BE CONSIDERED AS "WATCHING PROPERLY". Version 2.1

  17. REPORTING PRIVATE AID VERIFICATIONS EIGHTH WESTERN RIVERS REGION -- AID VERIFIER TRAINING VERIFYING A LIGHT'S CHARACTERISTICS • IN THE PREVIOUS EXAMPLE, THE LIGHT SHOWED: TWENTY FLASHES IN 58.4 SECONDS • ALL WORKSHEETS HAVE FIELDS FOR ENTERING THE RESULTS: FLASHES IN SECONDS • USE THE PREPRINTED FIELDS OR ENTER THE INFORMATION AS SHOWN ABOVE. Version 2.1

  18. REPORTING PRIVATE AID VERIFICATIONS • PREPRINTED PRIVATE AID WORKSHEETS HAVE FIELDS FOR ENTERING TIMING DATA. • TIME EACH LIGHT AND RECORD THE RESULTS IN THE PROPER FIELDS ON THE WORKSHEET • EXAMPLE: " 20 FLASHES IN 58.4 SECONDS" • 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: EIGHTH WESTERN RIVERS REGION -- AID VERIFIER TRAINING VERIFYING A LIGHT'S CHARACTERISTICS Number of Lights Nomenclature for Light Identification /Location 2 U/S, D/S 3 U/S, MIDDLE, D/S 4 MOST U/S, U/S, D/S, MOST D/S 5 MOST U/S, U/S, MIDDLE, D/S, MOST D/S Version 2.1

  19. IDENTIFYING SPECIFIC PRIVATE AID LIGHTS (EXAMPLE: FIVE-LIGHT FACILITY) • FOR THE MOST UPSTREAM LIGHT: • "MOST U/S = 10 Flashes in 59.4 Seconds", or • "#1 = 10 Flashes in 59.4 Seconds" • FOLLOWED BY: • "U/S = 10 Flashes in 61.3 Seconds", or • "#2 = 10 Flashes in 61.3 Seconds" • THEN: • "MIDDLE = 10 Flashes in 56.4 Seconds", or • "#3 = 10 Flashes in 56.4 Seconds" • AND: • "D/S = EXTINGUISHED", or • "#4 = EXTINGUISHED" • FINALLY: • "MOST D/S = 10 Flashes in 60.1 Seconds, Lamp Dim, Lens Cracked", or • "#5 = 10 Flashes in 60.1 Seconds, Lamp Dim, Lens Cracked" EIGHTH WESTERN RIVERS REGION -- AID VERIFIER TRAINING VERIFYING A LIGHT'S CHARACTERISTICS WHICH OF THE ABOVE EXAMPLES WOULD BE CONSIDERED AS "WATCHING PROPERLY"? Version 2.1

  20. EIGHTH WESTERN RIVERS REGION -- AID VERIFIER TRAINING VERIFYING A LIGHT'S CHARACTERISTICS REPORTING PRIVATE AID VERIFICATIONS • IF ANY TIMINGS ARE OUTSIDE THE TOLERANCE, CHECK “NO” AFTER THE ENTRY • “ IS LAMP TIMING CORRECT? YES ( ) or NO ( ) ____________________ ” • OTHERWISE, IF CORRECT, CHECK THE“YES” • “LAMP APPEARS TO BE ( ) GOOD, or ( ) DIM, or ( ) EXTENGUISHED REMARKS ________________” • IF A LIGHT IS EXTINGUISHED, CHECK “ ( ) Extinguished ” ON THE FORM AND INDICATE IF A LIGHT FIXTURE IS VISIBLE. • IF LIGHT IS GOOD, CHECK: “ ( ) Good ” ON THE FORM • IF THE VERIFICATION OF AN AID SHOWS THAT ALL ASPECTS ARE IN GOOD SHAPE (NO DISCREPANCIES), THEN CHECK THE BOX “ • “ ( ) WATCHING PROPERLY ” NEAR THE BOTTOM OF THE FORM. Version 2.1

  21. REPORTING PRIVATE AID VERIFICATIONS • IF ANY DISCREPANCIES, SUCH AS EXTINGUISHED LIGHTS, ARE CONSIDERED "CRITICAL" THEY SHOULD BE REPORTED VIA VHF MARINE RADIO TO THE AOR GROUP. "URGENT" DISCREPANCIES SHOULD BE REPORTED VIA PHONE TO THE GROUP OR THE AOR CUTTER. • RECORD THE FACT THAT SUCH COMMUNICATION WAS MADE ON THE FORM IN THE SECTION: “CRITICAL ( ) or ( ) URGENT DISCREPANCY REPORTED VIA VHF ( ) or ( ) PHONE TO : __________________________” • THE AID VERIFIER (AND ONLY THE AID VERIFIER) SHOULD PRINT THEIR NAME AND EMPL ID NUMBER AND SIGN THE WORKSHEET. • THE DATE AND TIME IS ALWAYS THE DATE AND TIME OF THE INSPECTION. EIGHTH WESTERN RIVERS REGION -- AID VERIFIER TRAINING VERIFYING A LIGHT'S CHARACTERISTICS NOTE: PER D8(OAN) ALL EXTINGUISHED LIGHTS ON PRIVATE AIDS AND BRIDGES ARE CONSIDERED "CRITICAL" DISCREPANCIES AND SHOULD BE HANDLED IN THE SAME MANNER AS "CRITICAL" FEDERAL AIDS (LOCAL NOTICES TO MARINERS, TRACKING, RE-VERIFICATION, ETC.). Version 2.1

  22. REPORTING THE RESULTS SUMMARY EIGHTH WESTERN RIVERS REGION -- AID VERIFIER TRAINING VERIFYING A LIGHT'S CHARACTERISTICS • ACCURATE AND THOROUGH REPORTING REQUIRED • COAST GUARD PERSONNEL RECEIVING YOUR REPORTS ARE EXPECTED TO TAKE ACTION BASED ON THE DATA REPORTED • MAY INVOLVE CONTACTING OWNER OF AID OR BRIDGE TO GET DISCREPANCIES CORRECTED • BE VERY SPECIFIC IN DESCRIBING DISCREPANCIES AND THE LOCATION (FOR EXAMPLE, WHICH LIGHT) OF EACH DISCREPANCY • ATTACH PICTURE IF POSSIBLE AND APPROPRIATE • NOTHING LESS THAN 100 PERCENT COMPLETE, DEFECT-FREE REPORTS ARE ACCEPTABLE Version 2.1
