### October 13, 2015 Docket Management Facility U.S. Department ofTransportation 1200 NewJersey Ave. SE West Building Ground Floor Room W12-140 Washington, DC 20590 Re: Drone Dynamics, LLC ExemptionNo. 12397 Regulatory DocketNo. FAA-2015-0651 Dear Sir orMadam: The FAA granted the request for exemption for Drone Dynamics, LLC by letter ofAugust 10,2015, as referenced above. Drone Dynamics, LLC hereby applies for an amendmentto the grantto include the additional unmanned aircraft systems identified below. The SmallUnmanned Aircraft Systems. The sUAS to be added (i) are lightweight rotorcrafts having a maximum takeoffweight ofless than 55 pounds (including payload), (ii) will be operated at a speed ofno more than 50 knots, (iii) all contain built-in safety features, and (iv) are produced by industry leaders DJI, 3D Robotics and Yuneec Electric Aviation. Proposed operations will be conducted under controlled conditions in airspace that is limited, predetermined, and access controlled. Operations will be subject to strict operating parameters to ensure at least an equivalent level ofsafety to currently authorized operations using manned aircraft. These aircraft are identified below.

These sUAS have commoncharacteristics. Each canbe operatedbytoggle orentirely by a touch-screen, mapbased interface. This means the operator onlyneeds to command the system where to go, andthe system does all the flying for the operator. They canbe operated inboth semi and fully autonomous flight modes, withthe operator simply clicking on a mapto create a pre-planned flight pathfor a flight. 

### Inaddition, the operator can create no fly zones ormaximum flight ranges and altitudes so the system cannot enter areas deemed unsafe or unnecessary to fly over. In addition, the sUAS have built-in intelligent fault handling capabilities which allowthemto detect a system fault while inthe air and automatically fly backto itstake-offlocation and land. Faults that canbe detected include: loss ofcommunication; exceeding pre-set windthresholds; and lowbattery levels. All flight operations are global positioning system (GPS) controlled, makingthe systems easy to navigate. At anypointifthe operator is not explicitly commanding the rotorcraft systemto move, the system automatically holds its GPS position. The flight control system employs not only GPS positioning but a variety ofsensors including sonar, barometric pressure, temperature, wind speed and others to ensure stability so long as wind thresholds are not exceeded. 

### Dll, 3DR and Yuneec all maintain online product informationportals with comprehensive downloadable operating and maintenance manuals, user guides, flight checklists, safety information and missionplanning instructions. Available also are instructional product and training videos along withrobust online blogs and product forums. 

### OperatingDocuments. The web addresses for the comprehensive operationmanuals/user guides for each aircraft are listed onAppendix "A". They are available openly onthe internet atthe manufacturers' website. Standard Operating Procedures, Pre-flight checklist and Post-flight checklist were filed as confidential documents withthe above-referenced application for exemption.
