RE: DOT/FAA Decision FAA

- 2016

- 5094

- 0003

Dear Brenda Robeson et al,

In response to your request for further clarification on how being granted our 333 exemption request

serves the public interest:

As the FAA concluded in Exemption No. 11213: "The enhanced safety and reduced environmental impact achieved using a UA with the specifications described by the petitioner and carrying no passengers or crew, rather than a manned aircraft of significantly greater proportions, carrying crew... gives the FAA good cause to find that the UAS operation enabled by this exemption is in the public interest."

Furthermore, our testing will take place in a 400 ft deep, decommissioned quarry owned by the company. This test area helps maintain a high level of safety exceeding the standard of an equivalent level of safety, and poses no burden on the national airspace as our flight testing activities will take place well below navigable airspace, and far from the person or property of non

- participants.

Elaborating further on how this exemption request is in the public interest, we will describe the mission of our research and development u sing small unmanned systems, as well as explain why this work

can not be accomplished under part 107 and must occur under a part 333 exemption:

Joby Aviation is accelerating the evolution of electric propulsion technologies and civil aircraft designs towards a quieter, more efficient, safer, more affordable, more neig hborly, and more environmentally friendly future. As our population grows and urban density increases, our need to move people and goods quickly, safely, and efficiently in and around urban environments is increasing. At the same time as the public need i s increasing, the tolerance for noise and environmental pollution is decreasing.

We are losing the land occupied by runways and helipads to other developments, and often the reasons cited for this are the cost, pollution, and noise associated with intern al combustion designs, as well as the amount of land required for conventional take

- off and landing aircraft. The low carbon

- footprint, quiet, cost effective electric VTOL technologies that we are developing are a critical piece of meeting these emerging n eeds, and will directly and significantly benefit the public at large in the years to come.

Before we embark on flight testing our full scale civil aircraft, we wish to operationally test our triple redundant flight computers, flight software, select avio nics, communications links, flight termination systems, and sensor suites using the hardware which will fly on the full scale aircraft. Carrying thishardware on a small unmanned system requires the aircraft be larger than the 55 lb allowance of Part

107 operations.

Our exemption request being granted would allow us to continue our work towards the realization of these public interests by enabling us to perform flight testing of representative hardware and soft ware on our unmanned quarter scale demonstrator before moving on to the full scale aircraft , which achieves the highest levels of safety and efficiency in bringing this transformative aircraft technology to the public.

Sincerely,
