NextGen Portfolio - Time Based Flow Management

Time Based Flow Management (TBFM) will enhance National Airspace System efficiency by using the capabilities of the TBFM decision-support tool, a system already deployed at all high altitude air traffic control centers in the contiguous United States. In particular, improvements in TBFM's core Time Based Metering capability and its trajectory modeler — an expansion of TBFM and its departure capabilities to additional locations — and enhancements to TBFM's departure capabilities, will enhance efficiency and optimize demand and capacity.

Capabilities in this portfolio will be leveraged to enable aircraft to maintain a spacing interval behind a preceding aircraft, further improving capacity and flight efficiency. Improvements will also enable controllers to more accurately deliver aircraft to the Terminal Radar Approach Control (TRACON) facility while providing the opportunity for aircraft to fly optimized descents.

Benefits

  • Capacity

    Takes advantage of the inherent capacity to meet airspace user demands at peak times and locations while minimizing restrictions on traffic flow. To respond to future growth, capacity must increase, along with corresponding increases in efficiency, flexibility, and predictability, while ensuring that there are no adverse impacts on safety and giving due consideration to the environment. The air traffic management system must be resilient to service disruption and the resulting temporary loss of capacity.

  • Efficiency

    Addresses the operational and economic cost-effectiveness of gate-to-gate flight operations from a single-flight perspective. In all phases of flight, airspace users want to depart and arrive at the times they select, and fly the trajectories they determine to be optimum.

  • Environment

    Contributes to the protection of the environment by considering noise, emissions, and other environmental issues in the implementation and operation of the aviation system.

  • Predictability

    The ability of airspace users and air traffic management service providers to deliver consistent and dependable levels of performance. Predictability is essential to users as they develop and operate their schedules.
