The facility also identified that when conditions are below 800 or 2NM, an interpretation will be needed as to whether landing aircraft on RWY 22R can transition through the critical area when a following landing aircraft is inside the FAF. However, when conditions remain above 800 or 2NM, the triple landing operation can be conducted using the mitigations developed. The facilities will begin planning shortly for the use of Y and a triple landing operation. It should be emphasized that if ultimately the Y localizer is a final solution, the equipment must be relocated to eliminate signal issues that currently exist. The second SRM panel focused on the waiver needed to allow simultaneous triple landing straight in approaches. The straight in triple landing operation remains the most desirable option because it will allow for the lowest minima on the approaches. This panel was comprised of local members, industry (Delta), CSA, HQ, AFS-410, and AFS- 450. This closely spaced operation has many different pieces and required extensive analysis. The panel ultimately determined that no high-level hazards existed with the operation. The panel analyzed numerous lower level hazards and developed a number of mitigations that will increase the safe operation of the procedure. Additional discussion will now need to occur with AFS-450 to determine how to move forward and re-analyze the tech memo safety study results to include the newly proposed mitigations and determine impact on the results. Briefing materials for the upcoming Delta and United Dispatch training is nearly complete. This training will be provided by the project leads to the dispatchers of both companies the last week of May in Atlanta and the second week of June in Chicago. The team leads have participated in the last two monthly National Flight Plan Filers telcons. An invitation was conveyed to all on the telcon that training was available and would be provided if anyone requested it. (Michael Taylor, CLE/DTW Article 114 D & I Liaison) NATCA PBN Co-Lead East In the past month in East, we worked on the PXT VORMON STARS, Northern ACR project, BOS Massport Study, and other VORMON activities. The work on the PXT STARs is almost complete, still need to work with N90 on the end points and lost comm procedures. This meeting is scheduled for the week of June 4th. Once we complete our work with N90 we can complete the procedure review and hand them off to FPT for publication. We had our 'kickoff' meeting for the Northern ACR Project the week of April 9th. ZBW, ZNY, and ZDC all participated, reviewed all designs, and verified they were correct. The pref routes still need to be reviewed in detail along with all the LOAs and other implementation activities. Our tentative implementation date is 1/30/2020. The FAA and Massport signed an MOU to look at environmental issues around BOS. The meeting for the Block 1 review occurred the week of May 7th. MIT briefed out their study on the first day and then we started looking at what could be accomplished on the following days. BOS, A90, ZBW, and Industry reviewed the study and documented what could work and what couldn't work. A big piece of the study is a 220k 'clean speed' on climb out to 10,000ft from RWY27 and RWY33L. There was a lot of documentation taken from the facilities and industry on the impacts this speed would create.
