This paper describes the recently established Commercial Aviation Alternative Fuel Initiative (CAAFI), including its goals and objectives, as well as presents an alternate fuel roadmap that was originally generated by industry and refined by the CAAFI stakeholders. CAAFI is designed to coordinate the development and commercialization of “drop-in” alternate fuels (i.e. fuels that can directly supplement or replace crude oil derived jet fuels), as well as exploring the long-term potential of other fuel options. The ultimate goal is to ensure an affordable and stable supply of environmentally progressive aviation fuels that will enable continued growth of commercial aviation. This initiative is organized into four sub-groups: Research and Development (R&D), certification, environment, and economics & business. The R&D group seeks to identify promising new drop-in alternate fuels, and to foster coordination of development efforts.

Important provisions are highlighted with respect to the additional airworthiness standards being considered by the Federal Avaiation Administration for small airplanes capable of carrying more than 10 occupants which are intended for use in air taxi and commercial operations. Information is presented on the background leading to these provisions and on their impact on manufacturers and operators. These new standards would result in a significant increase in the level of safety which is more commensurate with the class of operation, the increased occupant capacity, and the expanded volume of operations anticipated for these airplanes.

The rapid growth in digital computer technology and display systems has impacted most aerospace disciplines. The designer manufacturer operator and even airplane passengers are all affected by this technology boom. The FAA in its role of certifying new aerospace products is no exception. This paper will emphasize the changing methodology of the FAA certification process with some specific examples of recent flight test programs.
