Central Service Center (CSC) Performance Based Navigation (PBN)    

Eric Johnson is the Article 114 Representative for CSC PBN.    

Background: PBN Co-Leads are responsible for the oversight of designing, developing, and implementing PBN procedures and/or routes. Using a collaborative work group structure, PBN Co-Leads are also responsible for organizing work group activities and making every effort to reach agreement through a group consensus. Each FAA Service Center is represented by an FAA and NATCA Co-Lead, with the exception of the Eastern Service Center, which has two sets of Co-Leads due to the high demand of PBN resources for ongoing national initiatives.  

The CSA PBN Team attended several meetings hosted by the ESA PBN team to discuss T-route work that is being done for Atlanta Center (ZTL) VORMON. Indianapolis Center (ZID), Kansas City Center (ZKC), and Houston Center (ZHU) are all impacted and are having routes developed to mitigate the loss of VOR’s. The CSA PBN team held a meeting on May 19 to restart the Covington (CVG) single site project. Most of the project is still viable from previous work and we do not anticipate many changes. ZID, Clevland Center (ZOB), and Chicago Center (ZAU) are reviewing the portions that affect their facilities. Part of the CVG project is dependent on the upcoming Sandiford (SDF) project, so we will have to facilitate discussions between the SDF workgroup and CVG when the time is right. The CSA PBN team provided guidance to Flight Procedures Team (FPT) on May 19th reference a RNP style approach at Dallas Executive (RBD) using track to fix legs that will allow a more flexible approach while not being an RNP-AR procedure. Dallas Tracon (D10) and the City of Dallas are very happy with this development because it is allowing an IAP to a runway that was previously unable to have one due to surrounding airspace restrictions. The CSA PBN team was invited to air traffic discussions between Rockford (RFD), Chicago Tracon (C90), and ZAU reference new procedures at RFD on May 26 and June 9. These air traffic meetings are giving us a good insight to what the facilities want and need. This will be a complex project due to the design requirements around the Chicago area and the location of RFD. We have scheduled a PBN Single Site kickoff for RFD in August. I held an internal NATCA meeting on June 7th with Chicago (ORD) tower and Chicago Tracon (C90) reference the towers upcoming request for RNAV off the ground RNAV SID’s. Bennie Hutto, John Murdock, and I had a good discussion with both facilities on what pros and cons to new procedures will be on the operation in Chicago. These procedures will have some environmental complications. I attended a meeting with Minneapolis (MSP) and Minneapolis Tracon (M98) on June 11 reference a proposed RNP missed approach to runway 35 to help mitigate the large Arrival/Departure window (ADW) due to Converging Runway Operations (CRO). The airport, industry, and the facilities have formed a workgroup over the last year to come up with a plan for the airport and they are now bringing the service center into the loop. They are modeling their plan after the work that was done at Dallas Fort Worth(DFW). A waiver is still pending for DFW to reduce the ADW and industry is placing pressure on the agency to get the waiver approved. The waiver is supported by flight standards. I have also been attending 2-3 meetings a week for the National IFP workgroup. My subgroup has been making good progress with the FPT SOP and we are going to start having joint meetings weekly with the OSG subgroup to help integrate the two SOP’s together where they have common interest.  

Western Service Center (WSC) Performance Based Navigation (PBN)    

Chris Thomas is the Article 114 Representative for WSC PBN.    

Western PBN has several single site projects that we are actively working on this month. We are still working 100% remotely and there has been no update as to when we may start back to a pre-covid situation. Thus far, we have been able to complete all of our meetings via TEAMs or ZOOM and that has been working ok. Most, if not all, our facilities are back to normal watch schedules and that has required us to push out a few meeting dates in order to properly coordinate for facility SMEs. We have not run into any issues thus far with getting the proper people at our meetings.  

Below is a short summary of projects we’ve been working on this month:  

Memphis Center (ZME) VOR MON (Project Graceland) 

Western Service Area PBN Co-Leads have been assisting Eastern Service Area with a VOR MON project in Memphis. We’ve held two workgroup meetings so far and have coordinated with several terminal facilities for this project. Most of the work consists of removing victor airways tied to VORs that are being decommissioned and replacing them with new T-Routes. We have been working closely with the Atlanta Center (ZTL) VOR MON Team to combine projects in order to streamline the submission process for rulemaking. That work continues and should be completed in the next few weeks. We are still trying to coordinate some actions with a few smaller facilities. Again, work should be completed in before the next update. We still need to set up a workgroup with ZME and Memphis Tracon (M01) to develop a replacement for on conventional STAR into MEM. That work should take place sometime next month (July / August). Northern California – We have several procedures in the Oakland center (ZOA) and Northern California Tracon. (NCT) airspace that need work. In particular the ANNET and WNDSR STARs for Oakland (OAK). Northern California Tracon (NCT) has been requesting to amend these procedures since 2016.  

Southern California 

My Co-Lead and I have been working with the airspace manager at Southern California Tracon (SCT) to try and prioritize a couple of airports in the southern California area. There is a lot of work that has been requested for this area. We will be putting together a few workgroups for SCT and Los Angeles Center (ZLA) in the near future when we have a solid plan as to how we want to divide this work. We are trying to minimize the impact to SCT as much as possible and develop a reasonable plan for using their SMEs.  


We have been working a large T-Route project in Alaska that past several months. We have a follow up meeting scheduled with them next week. We are getting close to completing this project and handing it off to rulemaking. Next week’s meeting should help us complete most of the loose ends with this project.  

Salt Lake City  

Our Team has identified SLC as a priority airport for procedure implementation. There was several workgroup meetings held with SLC several years ago, but procedures were not implemented. We are trying to reach out to the facility at this time to see if they are still interested in their previous requests and if so how we can move forward getting them what they need.  

TARGETs Training  

I was able to attend a 4-day TARGETs class this week (6/7-6/10).
