nology; in 2001, more than 90 percent of available funds was spent on noise abatement (see Table 5-1 and Figure 5-1).

The current allocation of funding, which heavily favors airport noise abatement projects, is a consequence of the way funds are raised and appropriated. Most of these funds are raised from taxes on airline tickets for the purpose of subsidizing airport improvements, including noise abatement projects, and they are administered by the FAA through the Airport and Airway Trust Fund. Primary responsibilities for developing advanced aircraft technologies for source noise reduction, however, are assigned to NASA, which has no independent source of funding to support aeronautics research. Indeed, within NASA’s constrained budget, aeronautics research has fared poorly in competing against higher-
