ICAO/FAA Airport Certification Workshop INSPECTING TRAFFIC AND WIND INDICATORSCaribbean RegionSint MaartenJune1115, 2012 INSPECTING TRAFFIC AND WIND INDICATORSwind conessegmented circles and traffic pattern indicators. OBJECTIVESUsing and in accordance with reference documents and the course text, identify criteria for inspecting Aerodrome RequirementsProvide and maintain a wind coneFor each runway available for air carrieruse, a supplemental wind cone must be installed At the end of the runway, orAt least at one point visible to the pilot on final approach and prior to takeoff Aerodrome RequirementsWind direction indicators, including supplemental indicators, must be lighted if the airport is open for air carrier operations at night 4 Aerodrome RequirementsApplies to airports serving air carrierswhen no ATCT is operatingIf such an airport has a right hand trafficpattern, install around the wind cone aSegmented circleLanding strip indicatorTraffic pattern indicator RIGHT HAND TRAFFIC PATTERN RUNWAY FINALCROSSWINDDOWNWINDBASE SECTION 139.323(c) ACs contain methods and procedures for the installation, lighting and maintenance of traffic and wind indicators 7 PURPOSE OF WIND INDICATORSVisual display ofWind directionWind speed 8 TYPES OF WIND INDICATORSRecommendedWind sockNot recommendedTetrahedronWind tee 9 WIND SOCK OPERATIONRotate freely around a vertical shaftIn wind speeds of 3 knots or more, must indicate true wind direction +/When fully extended, indicate approximately 15 knots of wind 10 WIND SOCK SPECIFICATIONSWhite, yellow or orange to contrast withsurroundingsPrimary wind socks 8 or 12 feet longSupplemental wind socks 5 to 9 feet long 11 WIND SOCK SPECIFICATIONSSupport pole must bePerfectly verticalCapable of supporting the wind sockin wind speeds up to 75 knotsFrangible and cause minimum damage ifstruck by aircraft12 WIND SOCK SPECIFICATIONSLighting mustProvide minimum 2 footcandlesilluminationProvide no glare that would interferewith aircraft or ATCT operationsFor supplemental indicators, be visibleto aircraft from 1/2 mile away13 WIND SOCK SPECIFICATIONSPrimary wind indicators shouldBe centrally located with respect torunwaysNot violate any airport surfaces such as RSAs, OFZs or Part 77 surfaces14 WIND SOCK SPECIFICATIONSSupplemental wind indicators shouldBe a low mass typeBe no more than 10 feet highNot penetrate the OFZProvide wind information for a specificrunway end15 WIND SOCK SPECIFICATIONSSupplemental wind indicators shouldBe located 5001500' from the runway endBe on the left side of landing aircraft unless special circumstances existBe no closer than 250' from the runway CL NOTE: Preferred location is 1000' from the end and 250' left of CL16 LOCATION OF SUPPLEMENTAL WIND SOCK 17 TAXIWAYRUNWAY 250 ft200 ft 1000 ft 500 ft500 ftLOCATION AREA FOR SUPPLEMENTAL WIND CONE PREFFERED LOCATION SEGMENTED CIRCLE AIRPORT MARKER SYSTEM A system of pilot aids and air traffic control devices Must be highly visible and conspicuous to the pilot Lighting not required18 SEGMENTED CIRCLE AIRPORT MARKER SYSTEMMay consist ofSegmented circleLanding strip indicatorTraffic pattern indicatorClosed field signalWind direction indicatorLanding direction indicator (wind tee)Right turn indicator* Required by Part 13919 SEGMENTED CIRCLEAids the pilot in locating obscure airportsIndicates where traffic and wind indicators are located 20 SEGMENTED CIRCLEInstalled in a position of maximum visibilityIf possible, located around the primary wind cone 21 LANDING STRIP INDICATORNecessary when a righthand trafficpattern exists or is requiredLocated outside the segmented circleLaid out parallel tothe runway Landing Strip Indicator22 TRAFFIC PATTERN INDICATORUsed only onrunways withrighttraffic patterns Traffic PatternIndicators Landing StripIndicators 23 ACSI CHECKLIST FOR WIND INDICATORSFree rotation of wind sockCondition of wind sockLights operational/not missingSock color contrasts with surroundingsVertical (plumb) support 24 ACSI CHECKLIST FOR WIND INDICATORSOperational obstruction lighting if requiredPlacement not in the OFZ or safety areaunless approved by an airspace determinationAccurate information in the ACM 25 ACSI CHECKLIST FOR TRAFFIC INDICATORSIndicators not obscuredGround inside circle is free of vegetationand treated to provide added contrastConspicuous colorationWell maintainedIf required, landing strip and traffic patternindicators correctly positioned 26 27ENDLESSON QUESTIONS?
