- March 13 - 14 , 2018 , a PBN FWG meeting was convened at ZDV to address the need to replace outdated Cottonwood FMS Special Departure. Participants included Western Service Area (WSA) PBN Co - - ‐ Leads, NAVTAC, Flight Standards, OSG Environmental, ZDV, WSA Operations Support Group, WSA Flight Procedures Team, NBAA, NetJets, United, Delta, American and Southwest Airlines; - Flight Standards presented overview of Eagle's existing departure procedu res, challenges and the reasons the Cottonwood FMS departure needs replaced; outdated criteria, procedure can not be coded, unauthorized users flying it, Aspen airspace violations due to engine out por tion flown without notification; - Flight Standards developed two RNAV SIDS. APRES and BEVVR. Both SIDS have waivers to the initial climb area (ICA), bank angles gr eater than 20 degrees and require pilot initiated turn prior to departure end of runway (DER). Initially planned as s pecials, PRB agreed equivalent level of safety exists adequate to allow charting for public use. NBAA will primarily use the BEVVR which wa s designed RNAV - 1 after objections to the adv anced .03 RNP RNAV SID option. For increased level of comfort, FWG agreed to increase BEVVR takeoff minimums to 800 - - ‐ 2. - APRES is RNP .03, takeoff minimums 500 ‐ 2 w/534'/NM to 9, 300 (Compared to 815'/NM Public SID & 700'/NM for Cottonwood) ; - BEVVR is RNAV - - ‐ 1, takeoff minimums 500 ‐ 2 w/740'/NM to 10,200 (Compared to Cottonwood 700'/NM Climb) ; - A few industry participants expressed concern with the pilot ‐ initiated turn stating " RNAV off the ground is the only alternative for engagement and managing the aircraft on de parture by reducing workload." Remainder of the meeting, new design attempts with VI - - ‐ CF coded initial leg solutions were proposed. Various climb gradients (CG) up t o 918'fpnm discussed. AFS agreed to take an Industry agreed max CG and attempt a VI ‐ CF initial leg with two CG's – first LNAV engagement. - Remainder for obstructions. If successful, procedure may need to be a Special because of the number of waivers. Training may be requi red for equivalent level of safety. APRES and BEVVR RNAV SIDS currently scheduled for July 19, 2018 publication. The existing Cottonwood FMS Spec ial will NA/cancel concurrently; - March 27, 2018, Flight Standards is hosting post ‐ FWG S IM evaluation of the APRES and BEVVR RNAV SIDs in Boeing and Airbus ai rframes for Industry and PBN Co ‐ Lead observation. (Submitted by Josh Haviland, Western PBN Rep ) Eastern Service Area (ESA) PBN March 2018 The n otional designs are complete for the Capi tal Area Project. The design packages for IAD are being readied for environmental review and AIS development. We will attend the BWI and D . C . Roundtables April 24 and 26 , to present them with our notional designs. Several contr ollers from PCT and BWI tower will assist with the briefing.
