Improved Terminal and En Route Operations

Trajectory-Based Operations (TBO)

  • A distributed tool-supported process for addressing local airspace problems by modifying trajectories of one or more aircraft
  • Provides the capabilities, decision support tools, and automation to manage aircraft movement by trajectory
  • Implements RTAs (Required Time of Arrival) along the flight’s trajectory
  • Before flight leaves, trajectory is deconflicted by Air Traffic Control (ATC)

Time-Based Flow Management (TBFM)

  • Strategies to control the flow of flights arriving into highly congested terminal airspace at selected airports
  • Leverages capabilities of Traffic Management Advisor (TMA)

Time-Based Metering (TBM)

  • Delivery times of arriving aircraft from en route to terminal domains are coordinated to simplify merging and spacing
  • Allows reduced controller workload, less of a need to vector and assign airspeeds

Required Times of Arrival (RTA)

  • Capability of an FMS to “self-deliver” to a specified waypoint at a specified time

Improved Surface Operations

Taxi routing

  • Improved taxi route efficiency
  • Provides for manual input to close and reopen taxiway and runway segments

Airport configuration management

  • Improves responsiveness and effective use of airport resources
  • Provides automation to analyze, schedule, implement, and disseminate airport configuration changes
  • Provides capability to assess the impact of airport configuration changes

Scheduling and sequencing

  • Provides improved departure schedule integrity
  • Generates and displays a projected runway schedule showing departure and arrival demand
  • Provides Time Flow Management (TFM) constraints, such as expected departure clearance times to tower controllers

Runway assignments

  • Air Traffic Control (ATC) automation system assigns an aircraft to a runway based on departure fix and enables Air Navigation Service Provider (ANSP) personnel to accept/modify runway assignment

Optimized Profile Descent (OPD)

  • Enables arrival aircraft to descend from cruise altitude to final approach with significantly fewer level-offs
  • Enables lower and steadier power settings, and results in reduced fuel burn, lower emissions, and reduced noise
  • Reduced Carbon Dioxide: NextGen will reduce carbon emissions by 14 million tons by 2020
  • Reduced Fuel Consumption: NextGen will reduce fuel consumption by 1.4 billion gallons by 2020
  • Reduced Noise Emissions: Through quieter engines and procedures like OPDs, the number of people impacted by noise has been reduced to fewer than 500,000
  • OPD Benefits: Fuel savings at Miami International Airport (MIA): 50 gallons per flight; Reduced carbon dioxide emissions at MIA: 1,000 pounds per flight
Did You Know? $8.3 Million is the estimated money saved in fuel costs so far thanks to NextGen's improved flight routing
