Frequently Asked Questions

What is the FAA doing to help airports prepare for NextGen?

The scope of NextGen includes small and large airports. Today, airports can seek Airport Improvement Program (AIP) funding for the surveys, obstruction mitigation, and runway lighting that may be needed for new localizer performance with vertical guidance (LPV) approaches, or to achieve lower minimums with existing LPV approaches through improvements to airport design. At busier commercial service airports with Airport Surface Detection Equipment-Model X or Airport Surface Surveillance Capability, AIP funding has been used to deploy Automatic Dependent Surveillance–Broadcast (ADS-B) squitters for airport vehicles operating in the movement area.

The FAA continues to develop and roll out NextGen capabilities. The FAA also is working with industry, including airport representatives, through the NextGen Advisory Committee.

How does NextGen affect airport capacity, particularly during inclement weather?

A key benefit of NextGen is being able to retain visual flight rules-like capacity during inclement weather to maintain efficient and reliable operations at an airport. Improving closely spaced parallel runway operations (CSPO) is one way to do this. Overall, improvements to CSPO will be incremental, and maintaining safe separation from wake vortices still will be a requirement for aircraft flying a CSPO approach.

How does NextGen help to improve air traffic control surveillance at airports that don't have radar coverage?

Expanding surveillance to non-radar airports that are restricted to "one in, one out" operations will improve safety and capacity. In Colorado, the Wide Area Multilateration system reduces delays for up to 75 flights per day during ski season. The FAA also evaluated how to increase coverage from existing ADS-B locations where ground-based transceivers are being installed, and is adding new ADS-B stations in non-radar areas.

I'm interested in vehicle transponders for my airport to improve situational awareness. Where can I go for additional information?

Advisory Circular 150/5220-26, Airport Ground Vehicle ADS-B Out Squitter Equipment provides guidance on the development, installation, testing, approval, and maintenance of ADS-B Out squitter units for airport ground vehicles.

Where can I find information on newly published area navigation (RNAV) and required navigation performance approach procedures? How many localizer performance with vertical guidance (LPV) approaches has the FAA published?

The FAA's Global Navigation Satellite Services group provides updates on the RNAV inventory of approach procedures, including LPV.

My airport has an existing Wide Area Augmentation System (WAAS)-enabled localizer performance with vertical guidance or localizer performance approach, but what can I do to get better ceiling and visibility minimums?

Today the majority of general aviation aircraft that regularly fly under instrument flight rules in the National Airspace System are equipped with WAAS receivers. Airport managers, in collaboration with their users, can help to identify the need for new or improved Performance Based Navigation (PBN) procedures given their knowledge of how their airports are used. Steps to proceed are:

  • First, airport managers should work with their airport district office and flight procedures teams to identify the specific factors that were used to establish the existing approach minimums.
  • Next, airport managers can facilitate the aeronautical survey, obstruction mitigation, approach lighting, airport design improvements, or a combination of these actions that may be needed to achieve lower minimums. Some of these improvements could be eligible for AIP funds.
  • Finally, the airport manager would request that the FAA revise the approach procedures. Additional information on approach procedure development is available at the Instrument Flight Procedures (IFP) Information Gateway.

How do I request consideration for a new PBN instrument flight procedure (IFP)?

You can obtain additional information and submit requests at the FAA's IFP Information Gateway.
