| 摘要： | We appreciate the opportunity to testify today on the Federal Aviation Administrations (FAA) efforts to modernize airspace through Area Navigation (RNAV) and Required Navigation Performance (RNP). These initiatives are cornerstones of the Next Generation Air Transportation System (NextGen), which will move todays ground-based air traffic control system to a more efficient one that relies on satellite navigation and on-board aircraft avionics. The potential benefits of RNAV and RNP are significant and include shorter, more direct flight paths; improved airport arrival rates; enhanced controller productivity; fuel savings; and reduced aircraft noise. FAA and industry plan to invest billions of dollars over the next decade to bring about NextGen initiatives. To better ensure taxpayer dollars and private sector investments are used efficiently, FAA will need to carefully coordinate these efforts with industry stakeholders and within its own lines of business. RNAV and RNP are key to NextGens success, but fundamental issues need to be addressed. While RNAV and RNP have considerable industry support, some stakeholders are dissatisfied with the Agencys overall method for implementing these initiatives. Of particular concern is FAAs practice of laying most new routes over existing routes and the fact that air carriers are not using them. Stakeholders and FAA also disagree on the potential role, responsibilities, and oversight of non-Government third parties in speeding the adoption of RNP. Regardless of who develops the new procedures, FAA must provide one level of safety oversight. Today, I will cover two areas: (1) barriers and challenges affecting the successful implementation of RNAV and RNP and (2) the role and oversight challenges associated with use of third parties in developing new procedures. I will conclude with actions needed to ensure the safe and effective implementation of RNAV and RNP. |
