  • 5. Airport Roles
    5. AIRPORT ROLES As part of GDOT’s prior airport system plans, criteria were identified to assign each airport in the state system to a role or level. In Georgia, airport levels generally reflect the type of users each airport accommodates and the facilities and services that the airport has in place. Levels also typically reflect the airport’s relative importance, as it relates to meeting the state’s transportation and economic needs and objectives. Further, airport levels are often matched to the socioeconomic and demographic characteristics of the communities the airport serves. This chapter of the update to the Georgia Statewide Airport System Plan (GSASP) provides the following: • Review of current airport roles. • Comparison of Georgia state airport levels/roles to roles for Georgia airports established by the Federal Aviation Administration (FAA) in their ASSET Study or National Plan of Integrated Airport Systems (NPIAS). • Discussion of the need to consider change to current airport levels. • Recommendations for changes to current airport levels. Chapter 6, Airport Facility and Service Objectives, examines the ability of each airport to meet facility and service objectives that are applicable to each airport’s recommended level. 5.1 Factors That Influence Current Roles for Georgia Airports Levels for Georgia airports were established in the 2002 GSASP; the following factors were considered in the 2002 system plan to assign Georgia airports to a level: • Coverage: Percentage of the state contained in an airport service area. This factor included the establishment of a 30-minute service area for each airport via a geographic information system (GIS) drive time analysis.

  • FACT SHEET FAA Airport Privatization Pilot Program Gwinnett County Airport – Briscoe Field in Lawrenceville, Georgia Last Updated December 15, 2011
    FACT SHEET FAA Airport Privatization Pilot Program Gwinnett County Airport – Briscoe Field in Lawrenceville, Georgia Last Updated December 15, 2011 Background Like many other communities, Gwinnett County seeks significant new revenue sources through efficiencies, user fees, and the best use of assets. In 2009, a private investment group approached Gwinnett County officials with a concept that envisioned privatization of the operations, development, and maintenance of Gwinnett County Airport – Briscoe Field as part of the Federal Aviation Administration (FAA) Airport Privatization Pilot Program, including potential commercial passenger service. The FAA Airport Privatization Pilot Program affords the opportunity and framework for public sponsors of airports, like Gwinnett County, to explore privatization to generate private capital for airport improvements and development. In January 2010, the Board of Commissioners approved a resolution directing staff to submit a preliminary application to the FAA to reserve one of five slots in the Airport Privatization Pilot Program. Gwinnett County’s preliminary application to the FAA was the initial step in starting the lengthy process of studying the possibility of a public-private partnership to operate Gwinnett’s airport. The preliminary application identified the project objectives, described the proposed process and timetables, and provided current financial and operations statements. FAA acceptance of the pre-application does not commit the County to proceed with a final application. The FAA

  • FAA Runway Safety Report FY 2000
    FAA Runway Safety Report Runway Incursion Trends and Initiatives at Towered Airports in the United States, FY 2000 – FY 2003 August 2004 Preface THE 2004 RUNWAY SAFETY REPORT1 presents an assessment of runway safety in the United States for fiscal years FY 2000 through FY 2003. The report also highlights runway safety initiatives intended to reduce the severity, number, and rate of runway incursions. Both current progress and historical data regarding the reduction of runway incursions can be found on the Federal Aviation Administration’s (FAA) web site (http://www.faa.gov). Effective February 8, 2004, the FAA implemented an organizational change that created an Air Traffic Organization (ATO) in addition to its Regulatory functions. Safety Services, within the ATO, has assumed the responsibilities of the former Office of Runway Safety. Therefore, this FAA Runway Safety Report, which covers a period prior to the implemen- tation of the ATO, is the last in a series of reports that exclusively presents information on runway safety. Safety performance will be an integral part of future ATO products. 1 A glossary of terms and a list of acronyms used in this report are provided in Appendix A. Federal Aviation Administration 1 Executive Summary REDUCING THE RISKS OF RUNWAY INCURSIONS AND RUNWAY COLLISIONS is a top priority of the Federal Aviation Administration (FAA). Runway safety management is a dynamic process that involves measuring runway incursions as well as understanding the factors that contribute to runway collision risks and taking actions to reduce these risks. Runway incursion severity ratings (Categories A through D) indicate the potential for a collision or the margin of safety associated with an event.

  • RP011-21 Page 2
    RP011-21 Page 2 I. Background Gwinnett County is a cosmopolitan community in the northeast metropolitan Atlanta area that is home to a vibrant, diverse blend of people and places. It is the second most populous county in Georgia and has been one of the fastest-growing counties in the United States for several decades. Gwinnett County Airport is located on approximately 400 acres northeast of the city of Lawrenceville adjacent to Georgia State Route 316. The airport has a single 6,000-foot- long by 100-foot-wide grooved asphalt runway, capable of handling all light general aviation aircraft and most corporate jet aircraft in operation today. The airport has an Air Traffic Control Tower that is in operation from 7:00am to 9:00pm year-round. Gwinnett County Airport is currently the third busiest airport in the state with 127,285 operations annually, trailing only Atlanta (ATL) and DeKalb Peachtree (PDK) airports. The airport has long term master leases, with multiple sub-tenants located in the master lease buildings. The majority of the north side of the airport will soon be open to redevelopment including property current leased by one of two Fixed Base Operators. Projects currently underway at the airport include a parallel taxiway on the north side of the airport (Taxiway Y), construction of a corporate aircraft hangar site (the Central Basing Area) on the north side of the airport, rehabilitation and strengthening of Runway 7/25 to accommodate larger corporate aircraft, and a survey of potential obstructions to the airport’s approaches. Upcoming projects include an update to the airport’s master plan.

  • FAA Runway Safety Report
    AirTraffic Organization Safety Services FAA Runway Safety Report Safety Runway FAA FAA Runway Safety Report August 2005 August 2005 August Federal Aviation Administration 800 Independence Avenue SW Washington, DC 20591 www.faa.gov HQ-020705 Message from the Administrator Safety is the Federal Aviation Administration’s primary mission, and we are proud to say that the fatal accident rate for commercial aviation is the lowest it has been in aviation history. We have achieved this success with the help of our colleagues in commercial and general aviation, airports, industry, and other government agencies. The 2005 Runway Safety Report demonstrates that our collective efforts are indeed paying off. For the fourth consecutive year, the total number of serious runway incursions—instances where a plane comes too close to another plane or ground vehicle—has decreased. For the third consecutive year, there were zero Category A (most serious) runway incursions between two commercial jets. This is a great accomplishment and a tribute to everyone who works with us to ensure the safety of our runways and taxiways. As a result of our collective success, we are confronted with the challenge of reducing an already low runway incursion rate. Therefore, we must continue to focus our resources and energies where we will have the greatest impact in reducing risk. Thank you for helping us achieve our significant progress over the last four years. We will continue to strengthen our partnerships and further enhance training, procedures, infrastructure, and technology.
