Re: Drone Dynamics, LLC 

Exemption No. 12397 

Regulatory Docket No. F AA-2015-0651 

Dear Sir or Madam: 

The FAA granted the request for exemption for Drone Dynamics, LLC by letter of August 10,2015, as 

referenced above. 

Drone Dynamics, LLC hereby applies for an amendment to the grant to include the additional unmanned 

aircraft systems identified below. 

The Small Unmanned Aircraft Systems. The sUAS to be added (i) are lightweight rotorcrafts having a 

maximum takeoff weight ofless than 55 pounds (including payload), (ii) will be operated at a speed of no 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 of safety to currently authorized operations using manned aircraft. 

These aircraft are identified below. 

DJI aircraft 

• Phantom 2 

• Phantom 2 Vision + 

• Phantom 3 Standard 

• Phantom 3 Professional 

• Phantom 3 Advanced 

• Inspire 1 

• S 800 EVO

Yuneec Electric Aviation aircraft

• Typhoon QSOO 4K 

These sUAS have common characteristics. Each can be operated by toggle or entirely by a touch-screen, mapbased interface. This means the operator only needs to command the system where to go, and the system does 

all the flying for the operator. They can be operated in both semi and fully autonomous flight modes, with the 

operator simply clicking on a map to create a pre-planned flight path for a flight. In addition, the operator can 

create no fly zones or maximum 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 allow them to detect a system 

fault while in the air and automatically fly back to its take-off location and land. Faults that can be detected 

include: loss of communication; exceeding pre-set wind thresholds; and low battery levels. 

All flight operations are global positioning system (GPS) controlled, making the systems easy to navigate. At 

any point if the operator is not explicitly commanding the rotorcraft system to move, the system automatically 

holds its GPS position. The flight control system employs not only GPS positioning but a variety of sensors 

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 information portals with comprehensive downloadable 

operating and maintenance manuals, user guides, flight checklists, safety information and mission planning 

instructions. Available also are instructional product and training videos along with robust online blogs and 

product forums. 

Operating Documents. The web addresses for the comprehensive operation manuals/user guides for each 

aircraft are listed on Appendix "A". They are available openly on the internet at the manufacturers' website. 

Standard Operating Procedures, Pre-flight checklist and Post-flight checklist were filed as confidential 

documents with the above-referenced application for exemption.
