Airport Safety

New Radar That Will Help Prevent Accidents Is 4 Years Behind Schedule Gao ID: T-RCED-91-78 July 10, 1991

GAO discussed the Federal Aviation Administration's (FAA) new ground radar Airport Surface Detection Equipment (ASDE-3), focusing on: (1) delays associated with its installation; (2) the significance of problems uncovered during recent testing; and (3) the status of the FAA Runway Incursion Plan for enhancing ground safety at airports. GAO noted that: (1) the ASDE-3 deployment schedule has slipped almost 4 years and could slip even further due to software problems, changing requirements, and unforseen performance problems; (2) in spite of its split-target problems, ASDE-3 performance during heavy rain or fog is superior to the old system; (3) further delays in FAA deployment of ASDE-3 could occur, since some airports are not prepared to accept ASDE-3; (4) the new FAA approach to selecting airports for ASDE-3 installation does not consider historical information on runway incursions; (5) FAA failed to assign priorities to or estimate costs of the 44 Runway Incursion Plan projects; (6) although ASDE-3 is part of the FAA plan, it is not affected by FAA priority problems because it is under a production contract; and (7) FAA failure to set program priorities and funding levels could result in untimely completion of other projects, the dilution of available funds, and failure to give urgent problems the appropriate attention.
