program the Flight Management System (FMS) and fly the proper decent profile associated with the runw ay transition t hat was issued. On March 1, 2013, a memorandum was issued clarifying FA A JO 7110.65, Paragraph 4 - 7 - 1. The memorandum stated that Air Route Traffic Control Centers (ARTCC) should issue a landing direction and Terminal facilities should issue the runway tran sition to be flown. In limited situations when the procedures are covered in a letter of agreement, ARTCCs may issue the runway transition in lieu of Terminal. Once the aircraft is established on the runway transition, due to the behavior of some FMSs, runway changes and certain route changes become problematic for pilots. Prior to this change, controllers were required to vector aircraft to the final approach course when any runway change was issued once the aircraft pas sed the point 10 miles prior to t he runway transition waypoint. This change provides limited relief from that requirement. The change requires controllers utilizing descend via clearances on STARs with multiple runway transitions to issue 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 aircraft to the final approach course if a change in runways is made, but does contain strict qualifiers. PARC NAV WG The PARC NAV WG held is final quarterly meeting in Atlanta at the Delta Training Center, but due to budget constraints I had to particip ate in the meeting via telcon. This meeting is no t setup to be conducted via telcon, therefore it was extremely difficult to hear what was being discussed, but will provide what has been discussed in the past. RNP AR 50 second Rule Action Review Mike Cramer (MITRE) reported that he and Barry Miller (F AA) had completed a draft outline for a recommendation to remove the 50 - second requirement from RNP AR procedure design , reducing it to 15 seconds and handling exceptions through operational mitigation or non - approval. The outline was distributed the morn ing prior to the tel con and all members were asked to provide review and any feedback directly to Mike and Barry within the next week or two (mid - October). A - RNP Team Status Mike Cramer (MITRE) reported that the A - RNP subgroup had met on Sep tember 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 four A - RNP issues. Ron Renk (UAL) and Gary McMullin (SWA) were tasked with identif ying locations where reduction of the OEA for A - RNP would be beneficial, and locations where the larger OEA is currently limiting application 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 guidance. He produced a white paper for team review, which was distributed to the entire working group for review and comment jus t 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.
