Exemption No. 11808

Regulatory Docket No. FAA–2015–0473

Mr. Timothy Saffold

Executive Vice President

AECOM

2315 Briargate Parkway, Suite 150

Colorado Springs, CO 80920

Dear Mr. Saffold:

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.

By letter dated February 17, 2015, you petitioned the Federal Aviation Administration (FAA) 

on behalf of AECOM (hereinafter petitioner or operator) for an exemption. The exemption 

would allow the petitioner to operate an unmanned aircraft system (UAS) to conduct aerial 

photography, acquisition, and inspection of construction sites.

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 Skycatch.

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 
2

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, Certification procedures for products and parts, Subpart H—Airworthiness 

Certificates, 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, AECOM 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, AECOM is hereafter referred to as the operator.

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.
3

1. Operations authorized by this grant of exemption are limited to the Skycatch 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 

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 
4

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 

(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 
5

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 

FAA-published 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 

pre-determined 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 

(N−Number) markings in accordance with 14 CFR part 45, Subpart C. Markings must 

be as large as practicable.

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. 
6

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.

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 
7

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.

This exemption terminates on June 30, 2017, unless sooner superseded or rescinded.

Sincerely,

/s/

Re: Exemption Request Section 333 of the FAA Reform Act and Part 11 of the Federal 

Aviation Regulations from 14 CFR 61.113 (a) &(b); 91.103(b); 91.119; 91.121; 

91.151(a); 91.405 (a); 91.407(a) (1); 91.409 (a) (2); 91.417 (a) & (b). 

Dear Sir or Madam: 

Pursuant to Section 333 of the FAA Modernization and Reform Act of 2012 (the 

Reform Act) and 14 C.F.R. Part 11, AECOM, an engineering and construction company, 

hereby applies for an exemption from the listed Federal Aviation Regulations ("FARs") 

to allow commercial operation of its Small Unmanned Aircraft Systems ("sUAS") for 

aerial imaging for safety and monitoring of secured and controlled environment 

construction sites, so long as such operations are conducted within and under the 

conditions outlined herein or as may be established by the FAA as required by Section 

333. 

As detailed in this document and the attached Flight Manual, the requested 

exemption would permit the operation of sUAS under controlled conditions in airspace 

that is 1) limited 2) predetermined 3) controlled as to access and 4) would provide safety 

enhancements to the already best practices safety protocols followed by AECOM at each 

one of its construction sites. Approval of this exemption would thereby enhance safety 

and fulfill the Secretary of Transportation's (the FAA Administrator's) responsibilities to 

" ... establish requirements for the safe operation of such aircraft systems in the national 

airspace system." Section 333(c) of the Reform Act.

I. STATUTORY AUTHORITY FOR EXEMPTIONS 

The Federal Aviation Act expressly grants the FAA authority to issue exemptions. 

This statutory authority includes exempting civil aircraft, as the term is defined under 

§40101 of the Act, including sUASs, from the requirement that all civil aircraft must 

have a current airworthiness certificate. 

The Administrator may grant an exemption from a requirement of a regulation 

prescribed under subsection (a) or (b) of this section or any sections 44702-44716 of this 

title if the Administrator finds the exemption in the public interest. 49 U.S.C. §44701(f) 

See also 49 USC §44711(a); 49 USC §44704; 14 CFR §91.203(a) (1). 

Section 333(b) of the Reform Act assists the Secretary in determining whether 

sUAS may operate in the National Airspace System (NAS) without creating a hazard to 

the user, the public, or a threat to national security. If the Secretary determines that a 

sUAS "may operate safely in the national airspace system, the Secretary shall establish 

requirements for the safe operation of such aircraft in the national airspace system." Id. 

§333(c). 

AECOM's sUAS are multirotor vehicles, weighing 10 or fewer lbs. including 

payload. They operate under normal conditions at a speed of no more than 50 knots and 

have the capability to hover, and move in the vertical and horizontal plane 

simultaneously. The sUAS will operate only in the Pilot's visual line of sight at all times 

and will operate only within the sterile area described in the Confidential Skycatch Flight 

Manual, attached as Exhibit 1(hereinafter "the Manual"). Such operations will insure that 

the sUAS will "not create a hazard to users of the national airspace system or the public." 

Reform Act Section 333 (b). 

Given the small size of the sUAS involved and the restricted and sterile 

environment within which they will operate, our application falls squarely within the 

zone of safety (an equivalent level of safety) in which Congress envisioned that the FAA 

must, by exemption, allow commercial operations of sUAS to commence immediately. 

Also due to the small size of the sUAS and the low altitudes and restricted areas in which 

the sUAS will operate, approval of the application presents no national security issue. 

Given the clear direction in Section 333 of the Reform Act, the authority 

contained in the Federal Aviation Act, as amended; the strong equivalent level of safety 

surrounding the proposed operations, and the significant public benefit, including 

enhanced safety, the grant of the requested exemptions is in the public interest. 

Accordingly, AECOM respectfully requests that the FAA grant the requested exemption 

without delay. 
II. PUBLIC INTEREST 

This exemption application is expressly submitted to fulfill Congress' goal in 

passing Section 333(a) through (c) of the Reform Act. This law directs the Secretary of 

Transportation to consider whether certain unmanned aircraft systems may operate safely 

in the NAS before completion of the rulemaking required under Section 332 of the 

Reform Act. By granting an exemption the FAA will fulfill Congress's intent of allowing 

UAS to operate with significant safety precautions in low risk environments. 

The use of sUAS on a construction site can significantly reduce the risk to 

workers of falls while inspecting, surveying, or monitoring site progress. sUAS can 

inspect, photograph, and collect data on hard to get to areas that otherwise would require 

worker inspection. Falls are a leading source of workplace fatality and injury on 

construction sites i , and reducing falls through sUAS use for site imaging could save 

workers lives. 

Additionally, sUAS could replace the use of helicopters and small aircraft to 

monitor sites. The sUAS we propose to fly in this application are under five pounds, and 

carry no combustible material on board, as opposed to the much larger conventionally 

powered small aircraft. Shifting to sUAS from helicopters presents a marked safety 

increase for our workers and the public. 

Lastly, sUAS reduce the environmental impact by dramatically decreasing the 

energy used for aerial imaging and data collection over a construction site. Our sUAS use 

rechargeable lithium ion batteries, as opposed to fossil fuels burned in operation of small 

aircraft that are many hundreds of times heavier. 

III. EQUIVALENT LEVEL OF SAFETY 

AECOM proposes that the exemption requested herein apply to sUAS that have 

the characteristics and that operate with the limitations listed herein. These limitations 

provide for at least an equivalent or even higher level of safety to operations under the 

current regulatory structure because the proposed operations represent a safety 

enhancement to the already safe protocols followed on construction sites and imaging and 

surveying operations conducted with helicopters and other conventional aircraft. 

AECOM will be bound by the following limitations when conducting its sUAS 

operations under an FAA issued exemption: 

1. The sUAS will be less than 10 pounds. 

2. Flights will be operated within visual line of sight of a pilot. 

3. Maximum total flight time for each operational flight will be 30 minutes. The UAS 

calculates battery reserve in real time, and will return to its ground station with at 

least 20% battery power reserve should that occur prior to the 30 minute limit. 

1 "Commonly Used Statistics", Occupational Safety & Health Administration. Available at: 

https://www.osha.gov/oshstats/commonstats.html 

lb 
4. Flights will normally be operated at an altitude of 200 feet AGL, never exceeding 400 

feet AGL. 

5. Any site within 5 miles of an airport will not be flown without notification and 

approval of the local FAA Flight Standards District Office (FSDO) and airport 

controller. 

6. Crew for each operation will consist of the sUAS Pilot who will keep the sUAS 

within his visual line of sight at all times. 

7. The sUAS Pilot will be trained in flight, operations, and safety procedures as detailed 

in the Flight Manual. 

8. The sUAS will only operate within a confined "Sterile Area" as defined in the 

Manual. The Manual also requires the establishment of a"Security Perimeter" for the 

flight operations area. 

9. A briefing will be conducted in regard to the planned sUAS operations prior to each 

day's production activities. It will be mandatory that all personnel who will be 

performing duties within the boundaries of the safety perimeter be present for this 

briefing. 

10. All onsite personnel will consent to the UAS flyover on site by waiver, and the 

operator will obtain additional verbal or written consent of all persons who will be 

allowed within 100 feet of the flight operation. 

11. Pilot will have been trained in operation of UASs generally and received up-to-date 

information on the particular UAS to be operated as required by Section F of the 

Manual. 

12. Written and/or oral permission from the relevant property holders will be obtained. 

13. All required permissions and permits will be obtained from territorial, state, county or 

city jurisdictions, including local law enforcement, fire, or other appropriate 

governmental agencies. 

14. If the sUAS loses communications or loses its GPS signal, it will have capability to 

enter "loiter mode" and hover, reestablish satellite connection, and return to a predetermined location within the Security Perimeter and land. 

IV. DESCRIPTION OF SPECIFIC REGiJLATIONS 

14 CFR 61.113 (a) &(b): Private pilot privileges and limitations: Pilot in command 

Sections 61.113 (a) &(b) limit private pilots to non-commercial operations. Because the 

sUAS will not carry a pilot or passengers, the proposed operations can achieve the 

equivalent level of safety of current operations by requiring the Pilot operating the 

aircraft to have (1) completed a sUAS flight training course of 100 hours before flying a 

sUAS (See Section F of the Manual for more details) and (2) a Sport Pilot certificate. The 

FAA has previously acknowledged in prior grants of exemption under Section 333 that a 

commercial pilot's certificate was not necessary to operate a sUAS, but that the FAA 

could not waive the requirement for an FAA-issued pilot's license. A Sport Pilot 

certificate addresses the FAA's requirement that the Pilot in command have the requisite 

training and understanding of the National Airspace System, and also ensures that the 

Pilot is registered with the FAA and will not pose a risk to national security. The Sport 

Pilot certificate also does not require the Pilot to undertake the additional cost and time of 
additional manned aviation flight time that the Private Pilot's license requires and which 

will not translate to skill or competency operating the sUAS. 

Unlike a conventional aircraft that carries the pilot and passengers, the sUAS is remotely 

controlled with no living thing or cargo on board. Skycatch's sUAS is also operated by 

an autopilot, which greatly reduces the danger of human error. The area of operation is 

controlled and restricted to hard hat areas, and all flights are planned and coordinated in 

advance as set forth in the Manual. 

The sUAS to be operated hereunder is less than 10 lbs. fully loaded, carries neither a pilot 

nor passenger, carries no explosive materials or flammable liquid fuels, and operates 

exclusively within a secured area as set out in the Manual. Like other civil aircraft, 

operations under this exemption will be tightly controlled and monitored by the operator, 

pursuant to the Manual's requirements, and under the requirements and in compliance 

with local public safety requirements, to provide security for the area of operation as is 

currently done on active construction sites. The FAA will have advance notice of all 

operations. 

The risks associated with the operation of the sUAS are therefore diminished from the 

level of risk associated with commercial operations contemplated by Part 61 when 

drafted, and allowing operations of the sUAS as requested with a Pilot who has met the 

minimum requirements stated in Section F of the Manual achieves the level of safety 

contemplated by 14 C.F.R. §61.113 (a) & (b). 

14 C.F.R. 91.103: Preflight Action 

This regulation requires each pilot in command take certain actions before flight to 

ensure the safety of flight. An exemption is needed from this requirement as the Pilot will 

take separate preflight actions, including checking for weather conditions, checking flight 

battery requirements, checking takeoff and landing distances, and all other actions in the 

Preflight Checklist in the Manual. These actions will provide an equivalent level of 

safety. See Appendix A of the Manual. 

14 C.F. R. 91.119: 1Vlinimum Safe Altitudes 

Section 91.119 establishes safe altitudes for operation of civil aircraft. Section 91.119 (d) 

allows helicopters to be operated at less than the minimums prescribed, provided the 

person operating the helicopter complies with any route or altitudes prescribed for 

helicopters by the FAA. This exemption is for a multirotor craft that flies similarly to a 

helicopter, with vertical take off and vertical landing, which will typically operate at 

altitudes of 200 AGL, so an exemption may be needed to allow such operations. The 

sUAS will never operate at altitude higher than 400 AGL and will be in a restricted area 

with security perimeter, where buildings and people will not be exposed to operations 

without their pre-obtained consent. See Manual for detailed procedures. 
The equivalent level of safety will be achieved given the size, weight, speed of the sUAS 

as well as the location where it is operated. No flight will be taken without the permission 

of the property owner or local officials. Because of the advance notice to the property 

owner and any onsite personnel as outlined in the Manual, all affected individuals will be 

aware of the planned flight operations. Unlike flight operations with aircraft or rotorcraft 

weighing far more than the maximum 10 lbs. proposed herein, our sUAS will not carry 

flammable fuel. In addition, the low-altitude operations of the sUAS will ensure 

separation between sUAS operations and the operations of conventional aircraft that must 

comply with Section 91.119. 

14 C.F.R. 91.121: Altimeter Settings 

This regulation requires each person operating an aircraft to maintain cruising altitude by 

reference to an altimeter that is set "...to the elevation of the departure airport or an 

appropriate altimeter setting available before departure." As the sUAS may not have a 

barometric altimeter, but instead a GPS altitude read out, an exemption may be needed. 

An equivalent level of safety will be achieved by the operator, pursuant to the Manual 

and Safety Check list, confirming the altitude of the launch site shown on the GPS 

altitude indicator before flight. 

14 CFR 91.151 (a): Fuel requirements for flight in VFR conditions 

Section 91.151 (a) outlines fuel requirements for beginning a flight in VFR conditions. 

Our sUAS is limited to operations in sterile and controlled environments as outlined in 

the Manual, and has a limited range and flight time which require an exemption from 14 

CFR 91.151(a). 

The battery powering the sUAS provides approximately 35 minutes of powered flight. To 

meet the 30 minute reserve requirement in 14 CFR §91.151, sUAS flights would be 

limited to approximately 5 minutes in length. Given the limitations on the sUAS's 

proposed flight area and the location of its proposed operations within a predetermined 

area, a longer time frame for flight in daylight or night VFR conditions is reasonable. 

AECOM believes that an exemption from 14 CFR §91.151(a) falls within the scope of 

prior exemptions. See Exemption 10673 (allowing Lockheed Martin Corporation to 

operate without compliance with FAR 91.151 (a)). Operating the small sUAS, in a tightly 

controlled area where only people and property owners or official representatives who 

have signed waivers will be allowed, with less than 30 minutes of reserve fuel, does not 

engender the type of risks that Section 91.151(a) was intended to alleviate given the size 

and speed of the small UAS. Additionally, limiting sUAS flights to 10 minutes would 

greatly reduce the utility for which the exemption will be granted. 

An equivalent level of safety can be achieved by limiting flights to 30 minutes, or enough 

battery reserve to ensure that the sUAS lands at the ground station with at least 20% of 

battery power (as determined by the onboard monitoring system and the Pilot), whichever 

happens first. This restriction would be more than adequate to return the sUAS to its 

planned landing zone from anywhere in its limited operating area. 
Similar exemptions have been granted to other operations, including Exemptions 2689F 

5745, 10673, and 10808. 

14 CFR 91.405 (a); 407 (a)(1); 409 (a)(2); 417 (a) &(b): Maintenance inspections 

These regulations require that an aircraft operator or owner "shall have that aircraft 

inspected as prescribed in subpart E of this part and shall between required inspections, 

except as provided in paragraph (c) of this section, have discrepancies repaired as 

prescribed in part 43 of this chapter...," and others shall inspect or maintain the aircraft in 

compliance with Part 43. 

Given that these sections and Part 43 apply only to aircraft with an airworthiness 

certificate, these sections will not apply to AECOM. Maintenance will be accomplished 

by the operator pursuant to the flight manual and operating handbook as referenced in the 

Manual. An equivalent level of safety will be achieved because these small sUAS are 

very limited in size and will carry a small payload and operate only in restricted areas for 

limited periods of time. If inechanical issues arise the sUAS can land immediately and 

will be operating from no higher than 400 feet AGL. As provided in the Manual, the Pilot 

will ensure that the sUAS is in working order prior to initiating flight, perform required 

maintenance, and keep a log of any maintenance performed. Moreover, the Pilot is the 

person most familiar with the aircraft and best suited to maintain the aircraft in an 

airworthy condition to provide the equivalent level of safety. 

Pursuant to 14 C.F.R. Part 11, the following summary is provided for publication in the 

Federal Register, should it be determined that publication is needed: 

Applicant seeks an exemption from the following rules: 14 C.F.R. §21, subpart H; 14 

C.F.R 45.23(b);14 C.F.R. §§ 61.113( a) &(b);91.7 

(a); 91.9 (b) (2);91.103(b);91.109; 91.119; 91.121; 91.151(a);91.203(a) and (b); 91.405 

(a); 91.407 (a) (1); 91.409 (a) (2); 91.409 (a) (2) and 91.417 (a) & (b) to operate 

commercially a small unmanned vehicle (551bs or less) in construction operations. 

Approval of exemptions allowing commercial operations of sUAS in the construction 

industry enhances safety while reducing risk. Manned aircraft monitoring and surveying 

creates a greater risk because the craft are much larger, have combustible fuel, and carry 

an onboard human pilot. In contrast, a sUAS weighing fewer than 10 lbs. and powered by 

batteries eliminates virtually all of that risk given the reduced mass and lack of 

combustible fuel carried on board. The sUAS will carry no passengers or crew and, 

therefore, will not expose them to the risks associated with manned aircraft flights. 

The operation of small sUAS, weighing less than 10 lbs., conducted in the strict 

conditions outlined above, will provide an equivalent level of safety supporting the grant 

of the exemptions requested herein, including exempting the applicant from the 

requirements of Part 21 and allowing commercial operations. These lightweight aircraft 

operate at slow speeds, close to the ground, and in a sterile environment and, as a result, 
are far safer than conventional operations conducted with turbine helicopters operating in 

close proximity to the ground and people. 

Privacy 

All flights will occur over private or controlled access property with the property owner's 

prior consent and knowledge. Images taken will be of individuals who have also 

consented to being filmed or otherwise have agreed to be in the area where aerial 

photography will take place. 

Satisfaction of the criteria provided in Section 333 of the Reform Act of 2012--size, 

weight, speed, operating capabilities, controlled operating environment and operation 

within visual line of sight and national security — provide more than adequate justification 

for the grant of the requested exemptions allowing commercial operation of applicant's 

sUAS in construction industry pursuant to the Manual appended hereto. 

Sincerely,
