Traffic Flow Management System (TFMS)

Ryan Jacobs is the NATCA TFMS Representative 

Background:  TFMS is a data exchange system for supporting the management and monitoring of national air traffic flow. TFMS processes all available data sources such as flight plan messages, flight plan amendment messages, and departure and arrival messages. The National Airspace System (NAS) Data Warehouse assembles TFMS flight messages into one record per flight. TFMS is restricted to the subset of flights that fly under Instrument Flight Rules (IFR) and are captured by the EnRoute computers. TFMS is the main tool used at the Air Traffic Control System Command Center. 

The TFMS Deployment Team met several times over the last month. The top priority is R14 deployment and the surface viewer tool that will be deployed with it. We have not been able to perform regression testing due to COVID 19 restrictions.  

Also, during our meetings, we discussed a runway monitor tool and the design aspects that would be beneficial for a future deployment. We discussed having a graphical depiction of the volume in addition to numeric. We also looked at different ways to compute the column totals and discussed which time frames were relevant.  

We met together with the Flow Evaluation Team (FET) to discuss how to proceed when an airline files a TOS (Trajectory Option Set) that is a Coded Departure Route (CDR) and requires coordination. The anticipated behavior was that the TOS would be rejected since coordination was required prior to using that CDR. The FET indicated that they were in favor of allowing airlines to file any CDR they wanted as a TOS. If the TMC chose to apply the TOS they would need to make the necessary coordination. 

We met with TFDM and TBFM to discuss 3T schedules and important dates in the future. Currently TFMS schedules are in flux due to contract issues, and it is unclear when those issues might be resolved.  

There are three facilities remaining in order to complete tech refresh. Due to COVID 19 restrictions the timeframes remain uncertain until infection rates decrease enough to allow installers into the buildings.
