RNAV and PERFORMANCE BASED NAVIGATION (PBN): Dennis Kelly (PHL) is the Article 48 Representative for the criter ia work on RNAV and PBN initiatives. Mr. Kelly forwarded the information below for this week's update. · DEN – They report November RNP - AR count was 1536 approaches, bringing the total since they've been conducting the RNPs to approximately 26,000. Their total drops on days they have IMC because they don't have the waivers/criteria to conduct EoR to their favorable runway pairs and must sequence with straight - ins during IMC. Their widely spaced runway layout is not co nducive to arrivals during IMC. T heir fleet mix for RNP capable is 50 - 50, which is another limiting factor. · IAP cancellation initiative – Some underutilized and redundant VOR and NDB IAPs are finally being removed. Criteria developed was specified in the Federal Register on 6/27/20 14 and legacy IAPs that will be cancelled in the 12/10/2015, 02/04/2016, and 3/31/2016 publication cycles were proposed for cancellation in the Federal Register on 4/13/2015, which received no comments in opposition to their cancellation. On 12/10, 57 proc edures in 29 states will be removed. On 2/4/2016, 144 and on 3/31/2016, 133 procedures in virtual ly every state will be removed. A list is available. · National Procedure Assessment (NPA) Update – The operational stakeholders are developing criteria t o establish which SIDs and STARs can be removed. Some things considered: is it an ODP, regularly used, a special, for weather, for noise abatement , shared at other airport, etc. A recommendation was put forth that the FAA should identify ways to improve ef ficiency and apply automation to expedite the instrument procedure review cycle and the reduction in the overall amount of lines of minima in the NAS to reduce FAA workload and thus, save money. Circling minimum removals will be developed in collaboration with aviation stakeholders. The goal is to retain a minimum number of circling approaches at designated airports to meet current requirements for pilot training, airport access, and resiliency. These circling approaches would be phased out as training requ irements are updated and user demand for circling approaches subsides. · NSPP – Upcoming 12/10 procedures to be published for Non - Metroplex: SIDs/STARs/RNP: Upcoming 12/10 procedures to be published for Non - Metroplex: CVG 9 RNAV SIDs (top altitude), P WM 2 RNAV SIDs (top altitude) and 2 RNAV STARs, RIC 1 RNAV SID, ROA 3 RNAV SID (9 top altitude), CRW 1 RNP, YTSJ 4 RNAV SIDs, ABQ 2 RNPs, AUS 1 RNAV STAR, DFW 1 RNAV SID, SAT 3 RNAV SIDs (top altitude), AFA 3 RNAV STARs and 3 RNAV SIDs, BOI 7 RNAV STARs, B ZN 2 RNAV SIDs and RNO 3 RNAV SIDs (top altitude). · PARC NAV WG Items – Being worked are: o allowing RNP AR in precipitous terrain o RNP to ILS, GLS and LPV o RF use as it relates to minimum dist ance to and FAC and SIDs/STARs, o Climb gradien ts o RNP AR minimums o RNP values and transitory obstacles. · PBN Dashboard – There was a 3 - day meeting was held in Washington, D.C. to inform PBN Co - Leads about the methodology used to calculate metrics in the PBN Observer Dashboard, and to discu ss ways to promote use and c onfidence in the PBN Dashboard. This will be tough as there are many
