4 NextGen Airport Impacts Two of NextGen's principal goals are to increase the efficiency and capacity of the NAS, including both the en route airspace and airports. Efficiency is usually defined in terms of reduced aircraft operating times and fuel burn, which result from NextGen operational improvements such as PBN that have the potential to provide shorter flying distances and more fuel-efficient flight profiles.

5 Efficiency can also be increased on the ground through NextGen Surface Operations and Data Sharing improvements, which are designed to hold aircraft awaiting departure at their gates in "virtual queues" with engines off rather than in actual queues on taxiways with engines running. These surface operational improvements have been achieved by coordination of departures using data sharing and cooperative decision making among airports, airlines, and FAA air traffic management to reduce taxiway queues while preserving the equitable sequencing of departures.

6 Benefits for Uncongested Airports Environmental Issues Ground-based instrument landing systems (ILSs) support operations in low-visibility instrument conditions and enable air service providers and aircraft operators to maintain reliable air service.

8 EMISSIONS Fuel savings and corresponding emissions reductions are a potential NextGen benefit. Enabled en route arrival and departure profiles are intended to reduce fuel burn aloft, while NextGen surface operations and departure-metering programs are intended to reduce fuel burn and emissions on the airport surface.

10 Financial Issues Potential airport financial impacts from NextGen vary with the technologies being considered. In many cases the greatest costs will be borne by the FAA through their purchase of ATC hardware and assumption of operating and maintenance costs, and by aircraft owners through airplane equipage investments.

11 Infrastructure and Capital Planning to Prepare for or Adapt to NextGen Airports may wish to, or in some cases be required to, take action related to NextGen implementation: Obstruction clearance may be needed for new approach procedures with lower minimums and obstacle clearance surfaces. If your airport's obstruction map is not up to date, it can delay implementation of new procedures.
