 Exemption No. 11338 

 Regulatory Docket No. FAA−2015−0021 

Mr. Richard W. Zollinger, PE 

Principal Environmental Engineer 

R. W. Zollinger Consulting Engineers, Inc. 

1408 Coraopolis Heights Road 

Moon Township, PA 15108 

Dear Mr. Zollinger: 

This letter is to inform you that we have granted your request for exemption. It transmits our 

decision, explains its basis, and gives you the conditions and limitations of the exemption, 

including the date it ends. 

The Basis for Our Decision 

By letter dated January 6, 2015, you petitioned the Federal Aviation Administration (FAA) on 

behalf of R. W. Zollinger Consulting Engineers, Inc. (hereinafter petitioner or operator) for an 

exemption. The exemption would allow the petitioner to operate an unmanned aircraft system 

(UAS) to conduct aerial data collection including LIDAR, visual photography, and infrared 

remote sensing applications. 

See Appendix A for the petition submitted to the FAA describing the proposed operations and 

the regulations that the petitioner seeks an exemption. 

The FAA has determined that good cause exists for not publishing a summary of the petition 

in the Federal Register because the requested exemption would not set a precedent, and any 

delay in acting on this petition would be detrimental to the petitioner. 

Airworthiness Certification 

The UAS proposed by the petitioner is a DJI Phantom 2 
2 

The petitioner requested relief from 14 CFR part 21, Certification procedures for products 

and parts, Subpart H—Airworthiness Certificates. In accordance with the statutory criteria 

provided in Section 333 of Public Law 112−95 in reference to 49 U.S.C. § 44704, and in 

consideration of the size, weight, speed, and limited operating area associated with the 

aircraft and its operation, the Secretary of Transportation has determined that this aircraft 

meets the conditions of Section 333. Therefore, the FAA finds that the requested relief from 

14 CFR part 21, and any associated noise certification and testing requirements of part 36, is 

not necessary. 

The Basis for Our Decision 

You have requested to use a UAS for aerial data collection. The FAA has issued grants of 

exemption in circumstances similar in all material respects to those presented in your petition. 

In Grants of Exemption Nos. 11062 to Astraeus Aerial (see Docket No. FAA−2014−0352), 

11109 to Clayco, Inc. (see Docket No. FAA−2014−0507), 11112 to VDOS Global, LLC (see

Docket No. FAA−2014−0382), and 11213 to Aeryon Labs, Inc. (see Docket No. 

FAA−2014−0642), the FAA found that the enhanced safety achieved using an unmanned 

aircraft (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 in 

addition to flammable fuel, gives the FAA good cause to find that the UAS operation enabled 

by this exemption is in the public interest. 

Having reviewed your reasons for requesting an exemption, I find that— 

 They are similar in all material respects to relief previously requested in Grant of 

Exemption Nos. 11062, 11109, 11112, and 11213; 

 The reasons stated by the FAA for granting Exemption Nos. 11062, 11109, 11112, and 

11213 also apply to the situation you present; and 

 A grant of exemption is in the public interest. 

Our Decision 

In consideration of the foregoing, I find that a grant of exemption is in the public interest. 

Therefore, pursuant to the authority contained in 49 U.S.C. 106(f), 40113, and 44701, 

delegated to me by the Administrator, R. W. Zollinger Consulting Engineers, Inc. is granted 

an exemption from 14 CFR §§ 61.23(a) and (c), 61.101(e)(4) and (5), 61.113(a), 61.315(a), 

91.7(a), 91.119(c), 91.121, 91.151(a)(1), 91.405(a), 91.407(a)(1), 91.409(a)(1) and (2), and 

91.417(a) and (b), to the extent necessary to allow the petitioner to operate a UAS to perform 

aerial data collection. This exemption is subject to the conditions and limitations listed below. 

Conditions and Limitations 

In this grant of exemption, R. W. Zollinger Consulting Engineers, Inc. is hereafter referred to 

as the operator. 
3 

Failure to comply with any of the conditions and limitations of this grant of exemption will be 

grounds for the immediate suspension or rescission of this exemption. 

1. Operations authorized by this grant of exemption are limited to the DJI Phantom 2. 

when weighing less than 55 pounds including payload. Proposed operations of any 

other aircraft will require a new petition or a petition to amend this exemption. 

2. Operations for the purpose of closed-set motion picture and television filming are 

not permitted. 

3. The UA may not be operated at a speed exceeding 87 knots (100 miles per hour). The 

exemption holder may use either groundspeed or calibrated airspeed to determine 

compliance with the 87 knot speed restriction. In no case will the UA be operated at 

airspeeds greater than the maximum UA operating airspeed recommended by the 

aircraft manufacturer. 

4. The UA must be operated at an altitude of no more than 400 feet above ground level 

(AGL). Altitude must be reported in feet AGL. 

5. The UA must be operated within visual line of sight (VLOS) of the PIC at all times. 

This requires the PIC to be able to use human vision unaided by any device other than 

corrective lenses, as specified on the PIC’s FAA-issued airman medical certificate or 

U.S. driver’s license. 

6. All operations must utilize a visual observer (VO). The UA must be operated within 

the visual line of sight (VLOS) of the PIC and VO at all times. The VO may be used 

to satisfy the VLOS requirement as long as the PIC always maintains VLOS 

capability. The VO and PIC must be able to communicate verbally at all times; 

electronic messaging or texting is not permitted during flight operations. The PIC must 

be designated before the flight and cannot transfer his or her designation for the 

duration of the flight. The PIC must ensure that the VO can perform the duties 

required of the VO. 

7. This exemption and all documents needed to operate the UAS and conduct its 

operations in accordance with the conditions and limitations stated in this grant of 

exemption, are hereinafter referred to as the operating documents. The operating 

documents must be accessible during UAS operations and made available to the 

Administrator upon request. If a discrepancy exists between the conditions and 

limitations in this exemption and the procedures outlined in the operating documents, 

the conditions and limitations herein take precedence and must be followed. 

Otherwise, the operator must follow the procedures as outlined in its operating 

documents. The operator may update or revise its operating documents. It is the 

operator’s responsibility to track such revisions and present updated and revised 

documents to the Administrator or any law enforcement official upon request. The 
4 

operator must also present updated and revised documents if it petitions for extension 

or amendment to this grant of exemption. If the operator determines that any update or 

revision would affect the basis upon which the FAA granted this exemption, then the 

operator must petition for an amendment to its grant of exemption. The FAA’s UAS 

Integration Office (AFS-80) may be contacted if questions arise regarding updates or 

revisions to the operating documents. 

8. Any UAS that has undergone maintenance or alterations that affect the UAS operation 

or flight characteristics, e.g. replacement of a flight critical component, must undergo 

a functional test flight prior to conducting further operations under this exemption. 

Functional test flights may only be conducted by a PIC with a VO and must remain at 

least 500 feet from other people. The functional test flight must be conducted in such 

a manner so as to not pose an undue hazard to persons and property. 

9. The operator is responsible for maintaining and inspecting the UAS to ensure that it is 

in a condition for safe operation. 

10. Prior to each flight, the PIC must conduct a pre-flight inspection and determine the 

UAS is in a condition for safe flight. The pre-flight inspection must account for all 

potential discrepancies, e.g. inoperable components, items, or equipment. If the 

inspection reveals a condition that affects the safe operation of the UAS, the aircraft is 

prohibited from operating until the necessary maintenance has been performed and the 

UAS is found to be in a condition for safe flight. 

11. The operator must follow the UAS manufacturer’s maintenance, overhaul, 

replacement, inspection, and life limit requirements for the aircraft and aircraft 

components. 

12. Each UAS operated under this exemption must comply with all manufacturer safety 

bulletins. 

13. Under this grant of exemption, a PIC must hold either an airline transport, 

commercial, private, recreational, or sport pilot certificate. The PIC must also hold a 

current FAA airman medical certificate or a valid U.S. driver’s license issued by a 

state, the District of Columbia, Puerto Rico, a territory, a possession, or the Federal 

government. The PIC must also meet the flight review requirements specified in 

14 CFR § 61.56 in an aircraft in which the PIC is rated on his or her pilot certificate. 

14. The operator may not permit any PIC to operate unless the PIC demonstrates the 

ability to safely operate the UAS in a manner consistent with how the UAS will be 

operated under this exemption, including evasive and emergency maneuvers and 

maintaining appropriate distances from persons, vessels, vehicles and structures. PIC 

qualification flight hours and currency must be logged in a manner consistent with 

14 CFR § 61.51(b). Flights for the purposes of training the operator’s PICs and VOs 
5 

(training, proficiency, and experience-building) and determining the PIC’s ability to 

safely operate the UAS in a manner consistent with how the UAS will be operated 

under this exemption are permitted under the terms of this exemption. However, 

training operations may only be conducted during dedicated training sessions. During 

training, proficiency, and experience-building flights, all persons not essential for 

flight operations are considered nonparticipants, and the PIC must operate the UA 

with appropriate distance from nonparticipants in accordance with 14 CFR § 91.119. 

15. UAS operations may not be conducted during night, as defined in 14 CFR § 1.1. All 

operations must be conducted under visual meteorological conditions (VMC). Flights 

under special visual flight rules (SVFR) are not authorized. 

16. The UA may not operate within 5 nautical miles of an airport reference point (ARP) as 

denoted in the current FAA Airport/Facility Directory (AFD) or for airports not 

denoted with an ARP, the center of the airport symbol as denoted on the current FAApublished aeronautical chart, unless a letter of agreement with that airport’s 

management is obtained or otherwise permitted by a COA issued to the exemption 

holder. The letter of agreement with the airport management must be made available 

to the Administrator or any law enforcement official upon request. 

17. The UA may 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. 

18. If the UAS loses communications or loses its GPS signal, the UA must return to a predetermined location within the private or controlled-access property. 

19. The PIC must abort the flight in the event of unpredicted obstacles or emergencies. 

20. The PIC is prohibited from beginning a flight unless (considering wind and forecast 

weather conditions) there is enough available power for the UA to conduct the 

intended operation and to operate after that for at least five minutes or with the reserve 

power recommended by the manufacturer if greater. 

21. Air Traffic Organization (ATO) Certificate of Waiver or Authorization (COA). All 

operations shall be conducted in accordance with an ATO-issued COA. The 

exemption holder may apply for a new or amended COA if it intends to conduct 

operations that cannot be conducted under the terms of the attached COA. 

22. All aircraft operated in accordance with this exemption must be identified by serial 

number, registered in accordance with 14 CFR part 47, and have identification (NNumber) markings in accordance with 14 CFR part 45, Subpart C. Markings must be 

as large as practicable. 
6 

23. Documents used by the operator to ensure the safe operation and flight of the UAS and 

any documents required under 14 CFR §§ 91.9 and 91.203 must be available to the 

PIC at the Ground Control Station of the UAS any time the aircraft is operating. These 

documents must be made available to the Administrator or any law enforcement 

official upon request. 

24. The UA must remain clear and give way to all manned aviation operations and 

activities at all times. 

25. The UAS may not be operated by the PIC from any moving device or vehicle. 

26. All Flight operations must be conducted at least 500 feet from all nonparticipating 

persons, vessels, vehicles, and structures unless: 

a. Barriers or structures are present that sufficiently protect nonparticipating persons 

from the UA and/or debris in the event of an accident. The operator must ensure 

that nonparticipating persons remain under such protection. If a situation arises 

where nonparticipating persons leave such protection and are within 500 feet of 

the UA, flight operations must cease immediately in a manner ensuring the safety 

of nonparticipating persons; and 

b. The owner/controller of any vessels, vehicles or structures has granted permission 

for operating closer to those objects and the PIC has made a safety assessment of 

the risk of operating closer to those objects and determined that it does not 

present an undue hazard. 

The PIC, VO, operator trainees or essential persons are not considered 

nonparticipating persons under this exemption. 

27. All operations shall be conducted over private or controlled-access property with 

permission from the property owner/controller or authorized representative. 

Permission from property owner/controller or authorized representative will be 

obtained for each flight to be conducted. 

28. Any incident, accident, or flight operation that transgresses the lateral or vertical 

boundaries of the operational area as defined by the applicable COA must be reported 

to the FAA's UAS Integration Office (AFS-80) within 24 hours. Accidents must be 

reported to the National Transportation Safety Board (NTSB) per instructions 

contained on the NTSB Web site: www.ntsb.gov. 

If this exemption permits operations for the purpose of closed-set motion picture and 

television filming and production, the following additional conditions and limitations apply. 

29. The operator must have a motion picture and television operations manual (MPTOM) 

as documented in this grant of exemption. 
7 

30. At least 3 days before aerial filming, the operator of the UAS affected by this 

exemption must submit a written Plan of Activities to the local Flight Standards 

District Office (FSDO) with jurisdiction over the area of proposed filming. The 3-day 

notification may be waived with the concurrence of the FSDO. The plan of activities 

must include at least the following: 

a. Dates and times for all flights; 

b. Name and phone number of the operator for the UAS aerial filming conducted 

under this grant of exemption; 

c. Name and phone number of the person responsible for the on-scene operation of 

the UAS; 

d. Make, model, and serial or N-Number of UAS to be used; 

e. Name and certificate number of UAS PICs involved in the aerial filming; 

f. A statement that the operator has obtained permission from property owners 

and/or local officials to conduct the filming production event; the list of those 

who gave permission must be made available to the inspector upon request; 

g. Signature of exemption holder or representative; and 

h. A description of the flight activity, including maps or diagrams of any area, city, 

town, county, and/or state over which filming will be conducted and the altitudes 

essential to accomplish the operation. 

31. Flight operations may be conducted closer than 500 feet from participating persons 

consenting to be involved and necessary for the filming production, as specified in the 

exemption holder’s MPTOM. 

Unless otherwise specified in this grant of exemption, the UAS, the UAS PIC, and the UAS 

operations must comply with all applicable parts of 14 CFR including, but not limited to, 

parts 45, 47, 61, and 91.

The petitioner supports its request with the following information: 

Unmanned Aircraft System 

The UAS proposed by the petitioner is a proprietary design, conceived and constructed by DJI, 

and referred to as the DJI Phantom 2. This aircraft has four rotors and four motors in a 

quadcopter configuration (X4). The petitioner states that given the size, weight, speed, and 

limited operating area associated with the aircraft to be utilized by the applicant, an exemption 

from 14 CFR part 21, Subpart H (Airworthiness Certificates), subject to certain conditions and 

limitations, is warranted and meets the requirements for an equivalent level of safety under 14 

CFR pmi 11 and Section 333 of the FAA Modernization and Reform Act of 2012 (PL 112-95). 

The petitioner further states that UAS operated without an airworthiness cetiificate in the 

restricted environment and under the conditions and limitations proposed by the petitioner will 

be at least as safe, or safer, than a conventional aircraft (fixed wing or rotorcraft) operating with 

an airworthiness certificate issued under 14 CFR part 21, Subpart H and not subject to the 

proposed conditions and limitations. 

• The petitioner states that the unmanned aircraft (UA) to be operated under this request is 

less than 10 lbs with equipment loaded, flies at a speed of no more than 30 knots, carries 
other method to see the UA 

• The petitioner further describes that, in the event the UAS loses communications or its 

GPS signal, the UA will have the capability to return to a pre-dete1mined location within 

the Security Perimeter and land. It will also have the capability to abort a flight in the 

event of unpredicted obstacles or emergencies. The DJI Phantom has a failsafe function 

preloaded from the manufacturer. 

• The petitioner also states that the unmanned aircraft will be flown under 400 ft AGL. 

The DJI Phantom has an altitude read out which will be displayed on a video monitor 

along with a separate display on an IPAD. The altimeter will be reset to ground level at 

an altitude of zero feet. This will be pmi of a before flight checklist. A pre-flight, before 

takeoff checklist will be read and complied with for every flight. All of the flights will be 

operated in Class G airspace at this time. If flights occur under the shelf or inside 

Pittsburgh class B airspace. A COA application will be submitted. Notification to the 

local FSDO will be complied with. After communication with the FSDO appropriate 

local air traffic control will be notified for and appropriate NOT AM to be filed. 

• The petitioner states that the radio remote control that operates the UA is in FCC 

compliance. The device complies with part 15 of the FCC rules. The FCC ID is SS3-

201306002. 

The petitioner states that even though its UAS will have no airworthiness certificate, an 

exemption may be needed from 14 CFR § 45.23 as the UA will have no entrance to the cabin, 

cockpit, or pilot station on which the word "experimental" can be placed. Given the size of the 

UA, the petitioner notes that the two-inch lettering will be impossible. The petitioner asse1is that 

an equivalent level of safety will be provided by having the UA marked with the word 

"experimental" on the fuselage in compliance with 14 CFR § 45.29(f), in a location where the 

pilot, observer, and others working with the UA will see the identification. 

The petitioner states that the maintenance requirements in the pertinent sections of 14 CFR pmi 

91 are only applicable to aircraft with an airworthiness certificate in accordance with part 43. 

The petitioner states that its DJI Phantom does not have specific maintenance instructions; 

therefore the petitioner has developed a Preflight Checklist. The petitioner has also stated that it 

intends to follow any manufacturers' recommended instructions and procedures when those 

procedures exist for certain components of its DJI Phantom. 
product. 

UAS Operating Parameters 

The petitioner states that all flights will be operated within visual line of sight (VLOS) of a pilot 

and/or observer, and that the UA flights will be limited to a maximum altitude of 400 feet AGL. 

The petitioner assetis that an equivalent level of safety can be achieved given the size, weight, 

and speed of the UAS, as well as the location where it is operated. The petitioner states that the 

UAS will be operated within a safe operating perimeter, the boundaries of which will be 

determined by production personnel and the UA PIC based on the site-specific data collecting 

activities and speed of the UA required for the operation, and coordinated with the jurisdictional 

FAA FSDO and local government officials as applicable. The safety of conducting flights by a 

UA is drastically safer than the alternative. A helicopter is the alternative to gaining close high 

resolution photos or infrared data. The UA carries no flammable fuel and poses virtually no 

safety threat to any workers on site. 

With respect to preflight actions, the petitioner notes it may need an exemption from 14 CFR 

§91.103, because it will not have approved rotorcraft flight manuals, although there are 3 

checklists that will be adhered to prior to any flight. The petitioner asserts that an equivalent 

level of safety will be achieved by the PIC taking all preflight actions as set forth in their 

checklist, including reviewing weather, flight battery requirements. Additionally, the petitioner 

states that a briefing will be conducted prior to each day's data collecting regarding planned UA 

operations, and all personnel who will be performing duties within the boundaries of the safety 

perimeter will be required to attend. 

With respect to the fuel requirements, the petitioner notes that, in order to meet the 30 minute 

reserve requirements in 14 CFR §91.151, UAS flights would have to be limited to approximately 

0 minutes. The petitioner believes that an equivalent level of safety can be achieved by limiting 

flights to 15 minutes or 25% of battery power, whichever occurs first. 

The petitioner notes that it may need an exemption from 14 CFR §91.121, as its UAS may have a 

GPS altitude read out instead of a barometric altimeter. The petitioner asserts that an equivalent 

level of safety will be achieved. Specifically, the altitude information will be provided to the UA 

PIC via a digitally encoded telemetric data feed. Prior to each flight, a zero altitude initiation 

point will be established and confirmed for accuracy by the PIC. 
exemption, allow commercial operations of UAS to commence immediately.

 Also due to the 

size ofthe UA and the restricted areas in which the UAS will operate, approval of the application 

presents no national security issue. The petitioner states that, given the clear direction in Section 

333, the strong equivalent level of safety sunounding the proposed operations, and the 

significant public benefit, including enhanced safety, reduction in environmental impacts, and 

including reduced emissions associated with allowing UA for LIDAR remote sensing, visual 

photography, and IR remote sensing operations, granting the requested exemptions is in the 

public interest. 

Thank you for your timely consideration of this petition for exemption under Section 333, and 

please contact any of the undersigned individuals associated with RZI Environmental 

Management Consultants should any additional information be necessary to favorably consider 

this exemption petition. 

Sincerely,
