Part III Section L-1:

TFM-2 Size, Scope and Complexity Summary

The purpose of this document is to provide a summary of the size, scope and complexity of the work under this contract. Section C of the SIR comprises the full scope of work.

The Traffic Flow Management System (TFMS) supports the Federal Aviation Administration (FAA) Traffic Management personnel in providing efficiency-critical National Airspace System (NAS) services. Throughout each day, Traffic Managers use the TFMS to maintain near real-time situational awareness and predict areas which may experience congestion due to volume or capacity reductions or unusual demand increase. The TFMS is used to facilitate planning telecons every two hours to proactively plan impact mitigation strategies between the Air Traffic Control System Command Center (ATCSCC), Traffic Management Units (TMU) at all major Air Traffic Control (ATC) facilities (80 sites), and flight operators. TFMS remote sites are also located at other FAA and Govt. offices (39).

The TFMS supports strategic and tactical Traffic Flow Management (TFM) 24/7/365. It does this under all conditions, but becomes especially important when external factors such as adverse weather reduces NAS capacity and require proactive planning, coordination and adjustments to mitigate impacts, e.g., missed connections, canceled flights, increased fuel consumption, etc. The ATCSCC uses the TFMS to model and implement NAS-wide Traffic Management Initiatives (TMI) to make the most efficient use of available capacity to avoid gridlock and minimize delays. When delays are necessary, TFMS assigns departure times equitably and gives flight operators flexibility though submission of trajectory options and departure slot substitutions.

If core TFMS services were lost, the immediate impact would be greatly reduced national situational awareness, forcing TFM personnel to revert to contingency procedures limited to local situational awareness and ad hoc coordination across the NAS with reduced system efficiency, less flight operator flexibility, and increased probability of gridlock at major airports across the country.

Some TFMS products are also used by other FAA offices, Government agencies and flight operators who participate in Collaborative Decision Making (CDM), see http://cdm.fly.faa.gov.

The TFMS is also the FAA’s primary provider of flight information to the public, see http://www.fly.faa.gov. TFMS has 30 different applications users may interact with. Please refer to the J-3 Attachment, TFMS Functional Description, for more summary information on the TFMS products, tools, services and users.

The TFMS receives data on planned and active flights from various sources, forecasts demand for monitored NAS elements, and provides information and alerts to FAA users and other NAS stakeholders. Information on flights within the continental United States and inbound/outbound international flights is processed by the TFMS. Many industry vendors subscribe to non-sensitive TFMS data feeds. The TFMS has data interfaces with more than 30 FAA systems and external entities. Please refer to the J-2 Attachment, TFMS Interface Requirements Specification (IRS), for more information on TFMS external interfaces.

The TFMS is based on a multi-tiered, centralized Service Oriented Architecture (SOA) running custom application software (see table below) on commercial hardware and software infrastructure components, e.g., Java Enterprise Edition platform. Please refer to the J-3 Attachment, TFMS System/Subsystem Specification Document (SSDD), for more information.

The TFM Production Center (TPC), at the William J. Hughes Technical Center (WJHTC) in New Jersey, performs the core data processing and distribution of flight data functions. There is also a backup Disaster Recovery Center (DRC) in northern Virginia. Wide Area Network (WAN) services are provided via the FAA Telecommunications Infrastructure (FTI).

Key performance requirements include:

• The overall service Operational Availability must be at least 99.9% (including planned maintenance downtime).

• The system must process a minimum of 10,000 active flights concurrently.

• The system must support a minimum of 1,100 concurrent users with no degradation of performance.

The TFMS Service Desk operates 24/7/365 to monitor and control system components and help TFMS users with problems. This support is currently provided primarily by contract personnel onsite at the TPC. The ATCSCC also has onsite contract technical support daily from 0700 to 2300 Eastern Time. An average of 167 new service desk tickets were opened per month in calendar year 2015. An average of 34 per month were escalated to Second Level Engineering

(SLE).

Since there is no defined end state for TFMS, the FAA plans to continue incrementally adding functionality to TFMS in accordance with investment decisions. Two major TFMS releases are nominally planned for each calendar year with deployment in the spring and fall to avoid severe weather season and holiday moratoriums. Each release nominally requires several months of system engineering to develop updates to system-level requirements and design materials. The detailed design, development, integration test and deployment cycle is typically 18 months.

Concurrent work on some phase of four to five major releases is common.
