Dear Ms. Daniels: On August 5, we received a letter from you requesting additional information related to an amendment to exemption number FAA 2014-0942 for HUVRData, LLC. This letter provides the additional information requested in order to make a determination on our petition for an amendment. By letter dated May 2, 2015, we petitioned the Federal Aviation Administration (FAA) for an amendment to our current exemption for operations above 400 AGL using the AscTec Falcon 8. Our letter states that HUVRData, LLC wishes to operate within the limits the FAA has issued grants of exemption in circumstances similar in all material respects to those presented in our petition. 1. What altitude restrictions do you plan to set to ensure visual linc of sigllt is inaintained with the AscTech Falcon? The altitude restrictions will be established through an altitude assessment as follows: 1) Set the camera angle to 0 degrees, 2) Climb until the top of the structure is centered in the Controller video image, 3) Note the altitude of the aircraft, and 4) Set altitude limit at that altitude +50'. During the altitude assessment, the Observer will ensure visual contact maintained with the aircraft throughout. If it appears that visual contact may be compromised, the Observer will announce this to the PIC and the PIC shall recover the aircraft. 2. What procedures will be used and limits set to ensure visual line of sight when the system is above the structure? Once the altitude assessment is complete, the PIC shall climb the aircraft to the new maximum altitude while maintaining a vertical distance of 50' from the structure. The Observer shall position themselves in a location that, given their best estimate, will maintain visual contact throughout. Once in position, the PIC

C CGRAIA ~ ~ JMACAEROSPACE.AERO shall maneuver the aircraft around the structure testing the ability to maintain contact throughout the inspection. If necessary, HUVRData will employ more than one Observer to ensure visual contact can be maintained. 3. How do you ensure the protection of non-participating persons from debris fall-out in the event of an accident? Most HUVRData operating areas are remote and will not have non-participants in the vicinity. A 500 foot radius from the structure will be maintained to ensure all non-participating persons will not be affected from debris fall-out in the event of an accident. Barriers or structures will be present that sufficiently protect nonparticipating persons from the UA and/or debris in the event of an accident. The operator rnust ensure that nonparticipating persons remain under such protection. If a situation arises where nonparticipating persons leave such protection and are within the 500 feet radius of the structure, flight operations must cease immediately in a manner ensuring the safety of nonparticipating persons. 4. What limits will be applicd to operations within proximity to populated areas? Operations are not planned at this time near populated areas. If an operation is required near a populated area, prior approval from the FAA would be required and the limitations within this document and the HUVRData Operations Manual shall be maintained with respect to populated areas. The process and procedure for establishing area/security buffers shall ensure a secure area. If applicable to the site location, 50' outside of the 500' perimeter place traffic cones with the following signage: "Flight operation of a UAS are being conducted in the immediate vicinity. The UAS will be flown within a safety perimeter. Remain clear of cordoned off areas and UAS personnel." At the 500' perimeter radius, place traffic cones (or the equivalent) with visible rope (or its equivalent). Attach the following signage to the rope: "Flight operation of a UAS are being conducted within this perimeter. DO NOT CROSS THESE L1NES unless instructed to do so by an appropriate UAS Flight Team member." Prior to flight operations, attempt to contact the property owners, managers, or responsible parties, that UAS aircraft activities are about to begin and provide an estimated end time. Should the safety perimeter be breached, or appear to be in jeopardy, the PIC shall either land the aircraft immediately or perform a Return To Home proeedure. 5. What procedures and weather niiniinums will be used to address such factors as winds

J t,t AC A ER OSPAC E. AE R O at higher altitudes and fast moving weather phenomena? The UA will not be operated less than 500 feet below or less than 2,000 feet horizontally from a cloud or when visibility is less than 3 statute miles from the PIC or above aircraft wind maximums. If any of these minimums cannot be met during flight, the mission will be aborted and UA landed safely at the predefined location. Many of the structures being inspected will have their own weather station located on the structure or on the property at higlier altitudes If available, the structure/property weather data will be used to determine weather conditions and safe flight. If structure/property weather data is not available the PIC will bc responsible for determining safe flight by utilizing local weather forecast, METAR, TAF and AIRMET/SIGMET data. 6. How will you ensure that your UAS does not hit a support cable when conducting imaging near guyed masts? Most operating areas will not have support cables. If an operation is required where support cables are present, the PIC and Observer will be position to ensure that support wires are clearly identified and the flight plan takes into consideration these obstacles to ensure safe flight. Both the PIC and Observer will be required to ensure the obstacles are in clear sight during the flight. The PIC can require a third observer to focus only on the support cables/obstacle to ensure safe flight. The additional information has been submitted to our docket at www.regulations.gov and electronically via e-mail to 333exemptions(
