Mr. Shedden is participating in the rewrite of FA A Order 6510.4 (A/G Order). The last version was written in 1980. There are both new and existing requirements in the order dictating how Air Traffic must use A/G frequencies. NATCA will receive a briefing from the FAA ' s Spectrum office on September 27th t o better understand the issues surrounding these requirements. SURVEILLANCE BR OADCAST SERVICES (SBS) OFFICE : Eric Labardini (ZHU) is the Article 48 Representative to the SBS Office. Below is the update for SBS. The NATCA Surveillance and Broadcast Service s (SBS) team includes: Eric Labardini (ZHU), National SBS Article 48 Rep, Craig Bielek (A90), Dan Hamilton (SFO), National Airport Surface Surveillance Capability (ASSC) Rep, Andrew Stachowiak (I90), and Tom Zarick (ZDV), National Interval Management Rep . ADS - B: As of this update , 16,677 of 24,475 equipped aircraft are broadcasting ADS - B Rule compliant avionics in the NAS. SBS and Flight Standards (AFS) have been working to standardiz e how they count ADS - B traffic. The numbers above reflect about 10% of all traffic in the NAS are ADS - B Rule compliant and would be hig her if not for problem avionics that are normally scree ned by ATC automation systems. An issue not screened by automation systems but an important assumption for future ADS - B dependent applicatio ns is the br oadcast call sign of the user. ADS - B sends this information to automation systems for comp arison to the filed call sign. When a mismatch occurs , a Call Sign Mismatch (CSMM) alert can be generated. Data from ZAN showed over 2 , 100 CSMM alerts wer e gener ated in just one month (March). This prompted SBS Article 48 to recommend all MEARTS sites disable CSMM alerts and poll all ERAM sites to ga uge the extent of the problem. In July, over 44,000 CSMM conditions w ere present in all ERAM sites! Obviously , a lot of work is needed and fortunately CSMM alerts are disabled in al l ERAM, STARS, and ASDE sites. MEARTS sites e xpect to do the same very soon. The SBS PO rough estimate of avionics installation capacity nationwide is 50,000 aircraft per year . With th e January 1, 2020 deadline to equip quickly approaching, concern is high that equipage levels will fall short of the estimated tot al NAS fleet (100,000 - 160,000). Users that wait too close to 2020 may find that the availability of installers fall s short of demand. ADS - B IOCs have been completed at all En Rout e (ERAM and MEARTS) facilities. All but two ERAM sites have promoted ADS - B t o the top of their sort cells. Still awaiting a decision from ZMA and ZAB based upon their workloads. 77 of 155 Terminal sites have reached their ADS - B IOC a nd 73 are operating on Fusion. The remaining Terminal sites are ARTS 2E sites awaiting an upgra de to the ELITE (STARS) build. The Terminal ADS - B/Fusion tran sition proceeds in this order: Kickoff meeting, ADS - B Flight Inspectio n, ADS - B IOC, Fusion Operational Suitability Demonstration (OSD) and Fusion Operations. The most recent and upcoming Terminal events: Fargo (FAR) OSD completed Aug 23 Fairbanks (FAI) Flight Inspection completed Aug 24 Colorado Springs (COS) Kickoff meeting Aug 25 Atlantic City (ACY) Flight Inspection completed Aug 31 Gulfport (GPT) Flight Inspection completed Sept 7 Fargo (FAR) started Fusion Operations Sept 7 Spokane (GEG) Flight Inspection completed Sept 13 Tallahassee (TLH) Kickoff meeting Sept 15
