The change requires controllers utilizing descend via clearances on STARs with multiple runway transitions to issu e the runway transition or landing direction in conjunction with the descend via clearance. After the aircraft has passed the point 10nm prior to the runway transition waypoint, an additional change relieves controllers from the requirement to vector aircr aft to the final approach course with strict qualifiers when certain runway or course changes are made. PARC NAV WG The PARC NAV WG recent ly held a meeting in Seattle as well as some additional telcons , where the main topics of discussions have r esolved around the following: RNP AR 50 second Rule Action Review: Mike Cramer (MITRE) reported that he and Barry Miller (FAA) had completed a draft outline for a recommendation to remove the 50 - second requirement from RNP AR procedure design , reducing i t to 15 seconds and handling exceptions through operational mitigation or non - approval. The outline was distribut ed the morning prior to t he tel con and all members were asked to provide review and any feedback directly to Mike and Barry within the next we ek or two (mid - October). A - RNP Team Status: Mike Cramer (MITRE) reported that the A - RNP subgroup had met on September 13th (virtual meeting). The results were a "brainstorming" list of actions and topics that the group believes need to be worked out prior to coming to a recommendation on each of the 4 A - RNP issues. Ron Renk (UAL) and Gary McMullin (SWA) were tasked with identifying locations where reduction of the OEA for A - RNP would be beneficial, and locations where the larger OEA is currently limiting a pplication of A - RNP. Gary had identified sites and Ron is writing the draft material. Barry Miller (FAA) had an action to identify specifically which design assurance related requirements are the same for AR and A - RNP in the ACs and other regulatory guid ance. He produced a white paper for team review, which was distributed to the entire working group for review and comment just prior to this tel con. All interested members were asked to provide a review and feedback on the draft by mid - October directly to Mike and Barry. A MITRE action from the A - RNP group was to continue to add to the table of bank angle limitations in various aircraft and systems. The table is quite complete for Part 121, and Mike has sent it to NBAA (Rich Boll) for their input from Gul fstream, Cessna, and similar aircraft systems. RF.TF Concurrent Ops Action Review: Mike Cramer (MITRE) relayed that he and Mark Bradley (DAL) have completed a draft questionnaire for database and chart providers that will be used to add information to the options matrices regarding potential costs and complexity along the two primary paths. This will either be sent out by the SG or by individual operators from the SG in the next week or two. Mike also noted that the MITRE path analysis for the 10 - degree of fset trials in the 737 MAX engineering cab will be available by next week. Planning and Schedule Review : NAV WG Q4 F2F meeting – November 1 & 2, 2017, Delta (Atlanta), full day on the 1st and half day on the 2nd. Next tel con, November 29, 2017, 1 PM East ern.
