Dear Sir or Madam;

3. Additional operation s /missions

Each change request ed to the exemption is separate and independent and should be viewed as such with regard to approval, denial, or request for more information.

1 Night Operations

TANGODRONES LLC 333 petition for exemption docket FAA

- 2016

- 4886 under with docket FAA

- 2015

- 6988 (hereinafter the Exemption) without the purpose Night Operations

. TANGODRONES LLC herby requests an amendment to the Exemption to allow Night Operations that full y complies with the conditions of the Exemption. TANGODRONES LLC believes that we can safely operate UAV ’ s / UAS ’ s safely at night

, without increased harm to the public or property , at the same safety assumed for the original petition for exemption docket FAA

- 2016

- 4886

. The attached UAS night training program file has been emailed and not included into the public because it holds proprietary training information not intended for the public

. Night operations is a major need for TANGODRONES LLC when conducting inspections and closed set filming , certain temperature sensitive inspections, and search and res c ue

. Conditions for Night Operations

1. PIC Shall have a medical without wa i ver for color vision
2. PIC Sh all complete TANGODRONES night training
3. PIC Shall abide by the TANGODRONES night training currency requirements

We seek to amend this 333 petition for exemption docket FAA

- 2016

- 4886 on the basis of previously approved Exemption 16341 Industrial Skyworks (USA), Inc

. and seek the similar relief of night operations
and similar restrictions.

2

. Operations from a moving device or vehicleTANGODRONES LLC seeks exemp tion to operate from a moving device or moving land and water

vehicle s

. We feel that safety of the operation will not be compromised and the assumed safety of the original 333 petition for exemption docket FAA

- 2016

- 4886 will be maintained.

The conditions of operation would be such that the operator of the vehicle would :

1. be required to hold a valid driver’s licen se 2. abide by all local and state driving laws
3. cannot be the PIC of the UAV/UAS

4. cannot be the visual observer
5. cannot operate or be distracted by any electronic device or handheld device
6. cannot operate on any public right

- of

- way o r publicly maintained road without the controlling agency perm ission
7. trained according to TANGODRONES LLC vehicle training manual

The conditions of the moving device or vehicle the PIC would be in or on in such operation would:

1. have an open top to allow the visual observer and/or PIC to maintain open air visual line of sight.
2. B e operated in accordance with the local and state laws if applicable
3. B e operated no faster than 2 2.5 mph.

TANGODRONES LLC feels that with proper training and practice demonstrated in our training requirements we can safely operate from a moving vehicle. The attached UAS moving vehicle/device training program file has been emailed and not included into the public because it holds proprietary training information not intended for the public

. TANGODRONES LLC needs to o perate from a moving vehicle for the pur pose of operating longer distances required for our operations while still maintain ing line

- of

- sight during operatio ns such as search and rescue

. Since there is no restriction that the PIC be stationary during operations, r iding in or on a vehicle would be in many ways safer than walking for both the operator and those on the ground that could be affected if the operator tripped or stumbled wh ile moving under his or her own power.
