encouraged to report any identified events through ATSAP and via automation trouble reports. ● In order to reduce the number of safety compromising avionics events in the NAS, an effective, efficient response mechanism is needed. The Agency has deployed additional mitigations including Enhanced Validation (EV) and a No Services Aircraft List (NSAL). o The NSAL, aka "blacklist," is effective in dealing with chronic non- compliant aircraft, but it lacks the ability to respond quickly. As such it will likely always be needed as a backstop to compliance or enforcement issues. An issue identified and reported immediately takes a minimum of one day to place the aircraft on the NSAL. o Enhanced Validation (EV) shows the most promise operationally as it is a real-time response to invalid ADS-B targets. The latest update to EV already deployed within 15nm around a terminal radar has shown positive results. Additional EV techniques are being analyzed, including expanding the range beyond 15nm and further increasing the responsiveness. SBS engineering is working with Harris to incorporate these changes with additional EV parameters in 2018 and 2019. Advanced Interval Management (IM) ● The AIRS program is attempting to schedule another AIRS demonstration at Mitre in May to further promote familiarization of the program to ZAB controllers. A hands-on experience gives ZAB controllers a chance to view the concept while the con-ops is being built to help ensure the success of the program by meeting the needs of ZAB controllers. ● The AIRS team met in Phoenix the week of March 4. One topic discussed included the enhanced use of CAVS involving possible operations of visual separation through clouds on final approach using a CDTI Assisted Visual Separation tool. ● Con-ops draft work for AIRS continues with more comments/discussion in the following month. ASDE-X Tech Refresh ● The team continues to work on the RU communication upgrade plan. The goal is to be as efficient as possible with minimal impact to controllers as this is an operational system. Testing in SYR is underway. ASEPS (Space Based ADS-B) ● The Agency has split the original effort into multiple "pivots" to explore potential benefits of space-based ADS-B. ● The original concept for ASEPS now excludes SBA and instead focuses on ADS- C reduced separation efforts within ATOP under an effort separate from SBS. ● ZMA Caribbean airspace is currently the primary focus to prove SBA capability. A formal kickoff for this effort is planned for Dec. 18. An SRMP is now scheduled for April 23-25 at ZMA.
