I. Petitioner's Description 

ADvTECH Environmental Inc., was established in 1993 to provide streamlined, results-oriented 

consulting services in environmental compliance, site investigation, and remediation. Our team 

understands the impact of new Unmanned Aircraft Systems (UAS) technologies in the water 

resources industry and believes it necessary to adopt these technologies in order to sustain and 

grow business. Our team specializes in land use studies, geologic reconnaissance, and water 

resources and therefore quality control, data collection, and inspection are our top priorities. 

There are areas that have been unable to be reached for data collection due to large areas, water 

bodies, or rugged terrain. Examples would be flood control areas, large lakes, and water channels. 

With UAS, there is an inherent advantage to both data collection and overall understanding of 

pollution pathways that affect our water system. In California, this is especially critical due to the 

infrequency of rain, a large driving population, and the Pacific Ocean. We have an obligation as 

a company to offer the most accurate data and the most affordable value for our clients. 

Additionally, UAS serves to protect our employees from potentially dangerous situations due to 

environmental factors.

• ADvTECH Environmental! Petitioner's Description Page II 
~====================== II. Relevant Statutory Authority 

This petition for exemption is submitted to fulfill Congress' goal in passing Section 333(a) through 

(c) of the Reform Act. Congress has directed the FAA "to safely accelerate the integration of civil 

unmanned aircraft systems into the national airspace system." Pursuant to Section 333 of the 

Reform Act, the FAA Administrator is to consider whether certain unmanned aircraft systems may 

operate safely in the National Airspace ("NAS") before completion of the formal UAS rulemaking, 

based on the following considerations: 

• The UAS's size, weight, speed, and operational capability; 

• Operation of the UAS in close proximity to airports and populated areas; and 

• Operation ofthe UAS within visual line of sight ofthe operator (Id. At§ 333(b)(1)). 

If the Secretary determines that such vehicles "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". 

Additionally, the FAA Administrator has general authority to grant exemptions from its safety 

regulations and minimum standards when the Administrator decides a requested exemption is in 

the public interest. See 49 U.S.C § 44701(f) (permitting exemptions from §§ 44701(a), (b) and 

§44702- 44716, et seq.). A part requestion an exemption must explain the reasons why the 

exemption: (1) would benefit the public as a whole, and (2) would not adversely affect safety (or 

how it would provide a level of safety at least equal to the existing rules). See 14 C.P.R.·§ 11.81 

(petitions for exemptions). 

~ ADvTECH Environmental Inc. I Relevant Statutory Authority Page 12 
~====================== III. Qualifications for Approval Under Section 333 of the Reform Act 

The proposed operations in this petition for exemption qualify for expedited approval under 

Section·:3G3 of the Reform Act. Each of the statutory criteria and other relevant factors are 

satisfied. 

The proposed operations would permit the use of small and relatively inexpensive UAS under 

controlled conditions in airspace that is: (1) limited; (2) predetermined; (3) controlled as to access; 

and that (4) provides an increased level of safety beyond that existing when fixed or rotor wing 

aircraft are used to accomplish the· same purpose. 

Petitioner's UAS are rotorcraft, weighing less than approximately 6 pounds. They operate, under 

normal conditions, at low speed and have the capability to hover, and move in the vertical and 

horizontal plane. Petitioner's UASs will operate in line of sight and will only operate within a 

sterile area described in the enclosed· manuals. 

Given the small size of the UASs involved and the restricted sterile environment which they will 

operate, this petition exemption falls within the zone of safety i.e., an equivalent level of safety, in 

which congress desired the FAA to permit commercial UAS operations by exemption pending 

completion of formal mlemaking. Also, due to the size of the UASs and the restricted area in the 

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

Considering the clear direction in Section 333 of the Reform Act, the authority contained in the 

Federal Aviation Act, as amended, the equivalent level of safety surrounding the proposed 

operations, and the significant public benefit, the grant of the requested exemptions is also in the 

public interest. 

Accordingly, Petitioner respectfully requests the FAA grant the requested exemption without 

delay.

jg====================== 

IV. Description of Proposed Operations 

The following describes the policies and procedures for the Petitioner's proposed UAS operations. 

To assist the FAA in its safety assessment of Petitioner's proposed UAS operations, below is a 

summary of operational limitations and conditions which will ensure an equivalent or higher level 

of safety to operations conducted under current regulatory guidelines; 

1. The UAS total weight will weigh no more than 15 pounds. 

2. Flights will be operated with in Visual Line of Sight (VLOS) of the Pilot in Command 

(PIC) and/or observer. 

3. Maximum total flight time for each operational flight will be limited to the amount of 

time the UAS can be flown and still maintain a reserve battery power of no less than 

25% or 4 minutes. 

4. Flights will be operated at an altitude of no tnore than 200 feet AGL. 

5. Flights will be operated at a lateral distance of at least 100 feet from any inhabited 

structures, buildings, vessels, vehicles, or people not associated with the operation or 

have not signed a waiver in advance of the operation. 

6. Crew for each operation could consist of a UAS Pilot and a Visual Observer as 

warranted. 

7. The UAS Pilot will be trained for minimum of 50 flight hours on a vehicle that is flying. 

8. Prior to operation, a project packet will be created which includes all safety and 

operational information necessary to safely carry out the flight. 

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

day's missions. 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. Pilot and Visual Observer will at all times be able to communicate by voice. 

11. Pilot and Visual Observer will have been trained in operations of UAS generally and 

received up-to-date information on the particular UAS to be operated as required in the 

manual. 

12. Permission or a signature of waiver from the responsible party I managing persons will 

be obtained prior to flight. 

13. Appropriate 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 UAS loses communications or loses its GPS signal, the UAS will have the 

capability to return to a predetermined location within the property boundaries. 

15. Contingency plans will be in place to safely terminate flight if there is a loss of 

communication between pilot and observer. 

16. The UAS will have the capability to abort a flight in case of unpredicted obstacles or 

emergencies.

V. Regulations from which Exemption is Requested 

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

statutory-authority, by its terms, includes exempting civil aircraft, as the term is defined under§ 

50101 of the Act, including UASs, from its safety regulations and minimum standards when the 

Administrator decides a requested exemption is in the public interest. 

Petitioner seeks an exemption from several interrelated provisions of 14 C.P.R. Parts 21, 45, and 

91 for purposes of conducting Visual observations using UASs. Listed below are (1) the specific 

sections of 14 C.F .R. 

A. 14 C.F.R. Part 21, Subpart H - Airworthiness Certificates and 14 C.F.R. § 

91.203(a)(1). 

Given the size and limited operating area associated with the UAS to be utilized by the Petitioner, 

an exemption from Part 21, Subpart H, meets the requirements of an equivalent level of safety 

under Part 11 and Section 333 of the Reform Act. 

The Federal Aviation Act and Section 333 of the Reform Act both authorize the FAA to exempt 

aircraft from the requirement for airworthiness certificate, upon consideration of the size, weight, 

speed, operational capability, and proximity to airports and populated areas of the particular UAS. 

In all cases, an analysis of these criteria demonstrates that the UAS operated without an 

airworthiness certificate, in the restricted environment and under the conditions proposed, will be 

at least as safe as, or safer than, a conventional rotorcraft operating with an airworthiness certificate 

without restrictions and conditions of the proposed UAS operations. 

Equivalent Level of Safety 

The UAS to be operated hereunder, DJI Phantom 3 multi-rotor rotorcraft, DJI Inspire 1, and 3DR 

Solo weigh less than 6 pounds, carries neither a pilot nor passenger, carries no explosive materials 

or flammable liquid fuels, and operates exclusively within a secured and sterile area. Unlike other 

civil aircraft, the proposed operations will be controlled and monitored by the operator, as well as 

an observer, pursuant to the manuals' requirements. Moreover, the FAA will have advance notice 

of all operations conducted under this exemption as deemed appropriate. 

These safety enhancements, which already apply to civil aircraft operated in connection with 

existing inspection operations, provide a greater degree of safety to the Petitioner's employees, 

members of the public, and property owners than conventional operations conducted with 

airworthiness certificates issued under 14 C.F.R. Part 21, Subpart H. Lastly, the application of 

these same criteria demonstrates that there is no credible threat to national security posed by the 

UAS, due to its size, speed of operation, lack of explosive materials or Uammable liquid fuels, arid 

inability to carry a substantial external load. 

.... ADvTECH Environmental Inc. I Regulations in which Exemption is Requested Page 15 
•---------------

B. 14 C.F.R. Part 27 Airworthiness Standards: Normal Category Rotorcraft 

14 C.F.R. Part 27 sets forth the procedural requirements for airworthiness certification of normal 

category rotorcraft. To the extent the Petitioner's UAS would otherwise require certification under 

Part 27, Petitioner seeks an exemption from Part 27's air worthiness standards for the sa.rne reasons 

identified in the exemption request from 14 C.F.R. Part 21, Subpart H. 

C. 14 C.F.R. § § 91.9(c), 45.23(b) and 45.27(a): Aircraft Marking and Identification 

Requirements 

Petitioner seeks an exemption from the aircraft marking and identification requirements contained 

in 14 C.F.R. § § 91.9(c), 45.23(b) and 45.27(a). 14 C.F.R. § 91.9(c), Civil Aircraft Flight Manual, 

Marking and Placard requirements, provides that: No person may operate a U.S.-registered civil 

aircraft unless that aircraft is identified in accordance with Part 45 of this chapter. 14 C.F.R. § 

45.23(b), Markings of the Aircraft, states: When marks include only the Roman capital letter "N" 

and the registration number is displayed on limited, restricted or light-sport category aircraft or 

experimental or provisionally certificated aircraft, the operator must also display on that aircraft 

near each entrance to the cabin, cockpit, or pilot station, in letters not less than 2 inches nor more 

than 6 inches high, the words "limited, restricted, light-sport, experimental, or provisional," as 

applicable. Page 10 14 C.F.R. § 45.27(a), Rotorcraft, states: Each operator of a rotorcraft must 

display on that rotorcraft horizontally on both surfaces of the cabin, fuselage, boom, or tail the 

marks required by§ 45.23. Exemption from 14 C.F.R. § 45.23(b) is warranted because the UAS 

has no entrance to the cabin, cockpit, or pilot station on which the word "Experimental" can be 

placed. Moreover, given the size of the UAS, two-inch lettering will be impossible. Given the 

nature of the specific relief sought by this exemption request, Petitioner requires relief from the 

associated marking and identification requirements of § 45.27(a) and § 91.9(c), which would 

require compliance with § 45-.23(b ). 

Equivalent Level of Safety 

The equivalent level of safety for exemptions to the aircraft marking and identification 

requirements of§§ 91.9(c), 45.23(b) and 45.27(a) will be provided by having the UAS marked on 

its fuselage as required by § 45 .29(f). The FAA has previously issued the following exemptions to 

the aircraft marking requirements of§ 45.23(b): Exemption Nos. 10700, 10167 and 10167A. 

D. 14 C.F.R. § 91.9(b)(2): Civil Aircraft Flight Manual in the Aircraft 

Petitioner seeks an exemption from the flight manual requirements of 14 C.F.R. § 91.9(b)(2), 

which states:(b) No person may operate a U.S.-registered civil aircraft - ... (2) For which an 

Airplane or Rotorcraft Flight Manual is not required by § 21.5 of this chapter, unless there is 

available in the aircraft a current approved airplane or Rotorcraft Flight Manual, approved manual 

material, markings and placards, or any combination thereof. Given its physical dimensions, 

configuration and load capacity, the UAS has no ability to carry such a manual on the aircraft, not 

only because there is no pilot on board, but because there is simply no room or capacity to carry 

such an item on the aircraft. 

• ADvTECH Environmental Inc. I Regulations in which Exemption is Requested Page 16 
~---------------------- Equivalent Level of Safety 

The safety related purpose of this manual requirement can be equally satisfied by maintaining the 

UAS ·flight manual at the ground control point where the pilot flying the UAS will have immediate 

access. to: .. it. Accordingly, Petitioner requests an exemption from 91.9(b) (2)'s flight manual 

requirements, on the condition that the UAS flight manuals be available at the control point during . 

each operation. 

E. 14 C.F.R. § 91.7(a): Civil Aircraft Airworthiness 

Petitioner seeks an exemption from 14 C.F.R. § 91.7(a), which requires that a civil aircraft be in 

airworthy condition to be operated. Inasmuch there will be no airworthiness certificate issued for 

the UAS, should this exemption be granted, no FAA regulatory standard will exist for determining 

airworthiness. 

Equivalent Level of Safety 

The DJI Phantom 3, Inspire 1, 3DR Solo, have a stellar safety record, demonstrating that the UAS 

is airworthy. Further, given the size of the UAS and the requirements contained in the Manual for 

maintenance and pre-flight safety check lists, an equivalent level of safety will be provided. The 

FAA has issued the following exemptions to this regulation: Exemption Nos. 8607, 8737, 8738, 

9299, 9299A, 9565, 9565B, 10167, 10167A, 10602,32827, and 10700. 

F. 14 C.F.R. § 91.103: Preflight Action 

Petitioner seeks an exemption from 14 C.F.R. § 91.103, which requires a PIC to become familiar 

with specific information before each flight, including information contained in the FAA-approved 

Flight Manual on board the aircraft. While the PIC will be familiar with all information necessary 

to safely conduct the flight, an exemption is requested to the extent that an FAA-approved Flight 

manual is required on board the aircraft. 

Equivalent Level of Safety 

An equivalent level of safety will be provided by following the Aircraft Operations Manual. The 

PIC will take all required preflight actions - including reviewing weather, flight battery 

requirements, landing and takeoff distance, and aircraft performance data - before initiation of 

flight. The Aircraft Operations Manual will be kept at the ground station with the operator at all 

times. 

G. 14 C.F.R. § 91.109(a): Flight Instruction 

Petitioner seeks an exemption from 14 C.F.R. § 91.109(a), which provides that "no person may 

operate a civil aircraft (except a manned free balloon) that is being used for flight instruction unless 

that aircraft has fully functioning dual controls." UASs and remotely piloted aircraft, by their 

design, do not have functional dual controls. Instead, flight control is accomplished through the 

use of a box that communicates with the aircraft via radio communications. 

.... ADvTECH Environmental Inc. I Regulations in which Exemption is Requested Page 17 
~--------------- Equivalent Level of Safety 

Given the size and speed of the UAS, an equivalent level of safe training can still be performed 

without dual controls because no pilot or passengers are aboard the UAS, and all persons will be 

a safe distance away in the event that the UAS experiences any difficulties during flight Instruction. 

The FAA has approved exemptions for flight training without fully functional dual controls for a 

number of aircraft and for flight instruction in experimental aircraft. Exemptions include: Nos. 

5778K and 9862A. 

H. 14 C.F.R. § 91.119: Minimum Safe Altitudes 

Petitioner requests an exemption from the minimum safe altitude requirements of 14 

C.F .R. § 91.119. Section 91.119 prescribes the minimum safe altitudes under which aircraft may 

not operate, including 500 feet above the surface and away from any person, vessel, vehicle, or 

structure in non-congested areas. See 14 C.F.R. § 91.119(c). Section 91.119(d) allows for a 

helicopter to operate at less than those minimum altitudes when it can be operated "without hazard 

to persons or property on the surface," provided that "each person operating the helicopter 

complies with any routes or altitudes specifically prescribed for helicopters by the FAA." 

To provide the intended flood control facility inspections, lake inspections, storm channel 

inspections, the UAS is always operated below 200 feet AGL. Additionally, due the nature of the 

proposed operations, the UAS will maintain a lateral distance of at least 100 feet from inhabited 

structures, buildings, vehicles, and vessels, and from people not associated with the operation. 

Equivalent Level of Safety 

Compared to flight operations with rotorcraft weighing far more than the maximum 25 pounds 

proposed herein, and given the lack of flammable fuel, any risk associated with these operations 

is far less than those that presently exist with conventional aircraft. An equivalent level of safety 

will be achieved given the size, weight, and speed ofthe UAS, as well as the location where it is 

operated. As set forth in the Manual, the UAS will be operated in a restricted and sterile area, 

where buildings and people will not be exposed to operations without their pre-obtained consent. 

Because of the advance notice to the property owners and participants, all affected individuals will 

be well aware of the planned flight operations as set forth in the Manual. 

Furthermore, by operating at such lower altitudes, the UAS will not interfere with other aircraft 

that are subject to the minimum safe altitude regulations. Finally, the successful safety record of 

the DJI Phantom 3 multi-rotor rotorcraft, DJI Inspire 1, and 3DR demonstrates that the UAS can 

be safely used at these lower altitudes and closer operating environments. 

I. 14 C.F.R. § 91.121: Altimeter Settings 

This petition seeks an exemption from 14 C.F .R. § 91.121, which requires a person operating an 

aircraft to maintain cruising altitude or flight level by reference to an altimeter that is set to the 

elevation of the departure airport or barometric pressure. An exemption is required because the 

UAS does not have a barometric altimeter, but rather a GPS altitude read out. 

• ADvTECH Environmental Inc. I Regulations in which Exemption is Requested Page 18 
Equivalent Level of Safety 

An equivalent level of safety will be achieved by following the procedures set forth. The operator 

will €Qp.fip:n the altitude of the launch site shown on the GPS altitude indicator before flight. 

Moreover, the PIC will use the GPS altitude indicator built in to the UAS to constantly monitor 

height, thus ensuring operation at safe altitudes. 

J. 14 C.F.R. § 91.151(a): Fuel Requirements for Flight in VFR Conditions 

Petitioner requests an exemption from 14 C.F .R. § 91.151 (a)'s fuel requirements for flight in VFR 

conditions. Section 91.151 states: 

No person may begin a flight in an airplane under VFR conditions unless (considering wind 

and forecast weather conditions) there is enough fuel to fly to the first point of intended 

landing, and assuming normal cruising speed- (1) During the day, to fly after that for at 

least 30 minutes; or (2) At night, to fly after that for at least 45 minutes. Here, the battery 

powering the DJI Phantom 3 multi-rotor rotorcraft, DJI Inspire 1, and 3DR provides 

approximately 15 minutes of powered flight. To meet the 30 minutes reserve requirement 

in 14 C.F.R. § 91.151, UAS flights could not be conducted. Given the limitations on the 

UAS's proposed flight area and the location of its proposed operations within a 

predetermined area, a safety margin based on a reserve amount of battery life is needed. 

Petitioner will not be conducting any UAS flights at night. · \. 

Equivalent Level of Safety 

An equivalent level of safety will be achieved because the operations will be conducted on-site 

without significant transit time by the UAS. All flights will be planned to be terminated with no 

less than 25% reserve battery power still available. This restriction would be more than adequate 

to return the UAS safely to the ,ground and its planned landing zone from anywhere in its limited 

operating area even in the event of an unexpected occurrence. Operation of the UAS with less than 

30 minutes of reserve fuel does not include the type of risks that Section 91.151(a) was intended 

to alleviate given the size and speed of the small UAS, and the proximity of the flight operation to 

the landing zone. Moreover, operation will be limited to controlled areas where only people and 

property owners, or official representatives who have signed waivers will be allowed. This request 

for exemption falls within the scope of prior exemptions, including Exemption Nos. 10673, 2689F, 

5745, 10673, and 10808. 

K. 14 C.F.R. § 91.203(a) and (b): Carrying Civil Aircraft Certification and Registration 

Petitioner seeks an exemption from civil aircraft certification and registration requirements of 14 

C.F.R. § 91.203(a) and (b). The regulation states in part: 

(a) Except as provided in§ 91.715, no person may operate a civil aircraft unless it has within it the 

following: 

(1) An appropriate and current airworthiness certificate ... 

~ ADvTECH Environmental Inc. I Regulations in which Exemption is Requested Page 19 
jg~. --------------------- (b) No person may operate a civil aircraft unless the airworthiness certificate 

required by paragraph . 

(a) ofthis section or a special flight authorization issued under§ 9f.715 is 

displayed at the cabin or cockpit entrance so that it is legible to passengers or ~rew. 

In addition to the fact that Petitioner is seeking an exemption from the airworthiness certificate 

requirements, an exemption to this regulation is necessary because: (1) the UAS's configuration, 

load capacity and size does not allow it to carry certification and registration documents; (2) the 

UAS does not have a cabin or cockpit entrance at which documents could be displayed; and (3) 

there are no passengers or crew for whom the certificates need to be displayed. 

Equivalent Level of Safety 

To the extent these regulations are applicable to the proposed UAS operations, an equivalent level 

of safety will be achieved by keeping these documents at the ground control point where the PIC 

will have immediate access to them. 

The FAA has issued numerous exemptions to this regulation, including: Exemption Nos. 

9565, 9665, 9789, 9789A, 9797, 9797A, 9816A, and 10700. 

L. 14 C.F.R. § 91.405(a), 91.407(a)(l), 91.409(a)(2); 91.417(a) and (b): Maintenance 

Inspections 

Petitioner also seeks an exemption from the maintenance inspection requirements contained in 14 

C.F.R. § 91.405(a), 91.407(a)(l), 91.409(a)(2); 91.417(a) and (b). These regulations specify 

maintenance and inspection standards in reference to 14 C.F.R. Part 43. See, e.g., 14 C.F.R. § 

91.405(a) (stating that each owner or operator of an aircraft "[s]hall have the aircraft inspected as 

prescribed in subpart E of this part and shall between required inspections ... have discrepancies 

repaired as prescribed in part 43 of this chapter"). An exemption to these regulations is needed 

because Part 43 and these sections only apply to aircraft with an airworthiness certificate, which 

the UAS will not have, 

Equivalent Level of Safety 

An equivalent level of safety will be achieved because maintenance and inspections will be 

performed in accordance with the Aircraft Operations Manual. 

The operator will ensure that the UAS is in working order prior to initiating flight, perform required 

maintenance, and keep a log of any maintenance performed. 

The operator 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. 

If mechanical issues arise, the UAS's size and carrying capacity, and the fact that flight operations 

will only take place in restricted areas for limited periods of time during daylight hours, creates 

less risk than that associated with conventional rotorcraft performing the same operation. 

... ADvTECH Environmental Inc. I Regulations in which Exemption is Requested Page 110 
~====================== VI. Public Interest 

Granting ADvTECH Environmental, Inc.'s exemption request furthers the public interest. 

National policy set by Congress favors early integration of UAS into the national airspace in 

controlled, safe working environments such as those proposed in this petition. By their nature, 

flood control facilities, lakes, storm water channels, and evaporation ponds present unique 

difficulties for persons attempting to inspect and maintain these vital pieces of our water ways. 

Sending personnel to inspect dam structures and high walled flood storage facilities puts personnel 

at risk. These risks can be avoided by using a small UAS under controlled conditions to photograph 

and document the state of the equipment. This helps to facilitate repairs and identify issues before 

they become problems. The public deserves to have the highest level of quality control as they rely 

heavily on these facilities for flood and pollution protection. Employing the UAS in this capacity 

will further help to ensure their safety. 

Use ofthe UAS in lieu of a manned aircraft would enhance safety and reduce the environmental

VIII. Federal Registry Summary 

Pur~uant 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: 

ADvTECH Environmental, Inc. seeks an exemption from the following rules: 

14 CFR Part 21, Subpart H; 14 CFR Part 27; 14 CFR 45.23(b); 14 CFR 91.7(a); 14 CFR 

91.9(b)(2); 14 CFR 91.103; 14 CFR 91.109(a); 14 CFR 91.119; 14 CFR 91.121; 14 CFR 

91.151(a); 14 CFR 91.203 (a) & (b); 14 CFR 91.405(a); 14 CFR 91.407(a)(1); 14 CFR 

91.409(a)(2); 14 CFR 91.417 (a) & (b). 

Approval of these exemptions allowing commercial operations of small and lightweight unmanned 

aircraft ("UAS ") to conduct water body inspections will enhance safety by reducing risk to 

ADvTECH employees and clients, the general public and property owners. 

The DJI Phantom 3 multi-rotor rotorcraft, DJI Inspire 1, and 3DR weigh less than approximately 

6 pounds and powered by batteries, eliminates virtually all of that risk given the reduced mass and 

lack of combustible fuel carried on board. The UAS is transported to the designated survey area 

set up. It is not flown from an external location to-the work -site. The U AS will carry no passengers 

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

The operation of this small U AS 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 UASs operate at slow speeds, close to 

the ground, and in a sterile environment. As a result, they are far safer than conventional aerial 

survey and inspection operations conducted with fixed wing aircraft or helicopters.

Fly Safe 

• Calibrating the Compass: 

Make sure to calibrate the compass in fN8rY new flight location. The compass is Vf!l'l sensitive to electromagnetic interference, 

which can cause abnormal compass data leading to poor flight performance or even failure. Regular calibration is required for 

optimum performance. Recalibrate the compass when: a) The Aircraft Status Indicator is blinking red and yellow. b) Flying in a 

new location. 

• DO NOT calibrate your compass where there is a chance of strong magnetic interference, such as magnetite, parking 

structures, and steel reinforcements underground. 

• DO NOT carry ferromagnetic materials with you during calibration such as keys or cellular phones. 

• DO NOT calibrate beside massive metal objects. 

• If the Right Status LED is showing solid red, then try to calibrate again. If it is blinking red and yellow alternately after placing 

the aircraft on the ground, the compass has detected magnetic interference. Change your location. 

• P Mode: 

Safe to fly. In this mode, the Inspire 1 has a strong GPS signal and 

can use the VISion Positioning System allowing it to hover accurately 

in position indoors and out. If outdoors, this mode also means that a 

Home Point has been locked so that it can Return to Home if the 

control signal is lost. 

If you are not in this mode, toggle the Right 

Mode Switch to P position to enable it. 

The Flight Mode Switch is locked in P mode by default. 

Refer to the User Manual on how to unlock the switch. 

There are three states in P mode. 

P-GPS: GPS works best when outdoors in a wide open area, and 

your Inspire 1 uses GPS to hover in place when the GPS signal is 

strong. P-OPTI: If GPS is not available, the aircraft can use the 

Vision Positioning System to hover accurately. P-ATTI: Neither 

GPS or Vision Positioning System available, aircraft is using only 

its barometer for positioning, so only altitude is controlled. 

Note that the VISion Positioning System may not work properly when 

the Inspire 1 is flying over water; over surfaces without a clear pattern, 

or in a low light environment.

When the GPS signal is strong, the aircraft will be able to record a 

Home Point and return to the Home Point when needed. The GPS 

location is recorded when the GPS signal icon in the DJI Pilot app is 

either yellow or green. 

I

• 

The aircraft will return to the Home Point automatically in the following 

cases (all require a strong GPS signal). 

Smart RTH: When you press the RTH button on the remote controller 

or in the App. Low Battery RTH: The DJI Pilot app notifies users to take 

action when the battery level falls to a specified threshold . 

Failsafe RTH: When the remote controller signal is lost. 

• While returning home, Its altitude can be adjusted by the user to avoid obstructions. Tall buildings may affect the remote controller signal. 

The Failsafe Return to Home procedure will be triggered If the signal Is lost Be sure fty higher than any nearby buildings to avoid crashing. 

• Flight Limits: 

The Inspire 1 is not permitted to fly within no-fly zones as specified 

by local laws and regulations. Please visit here: 

http://flysafe.dji.com/no-fly for more information. 

• Environmental Considerations: 

1. Do not fly in severe weather conditions. This includes high wind, snow, rain and smog. 

2. Only fly in open areas. Tall buildings and steel structures may affect the accuracy of the onboard compass and GPS signal. 

3. Avoid from obstacles, crowds, high voltage power lines, trees or bodies of water. 

4. Minimize electromagnetic interference by not flying in areas with high levels of electromagnetism, including mobile 

phone base stations or radio transmission towers. 

5. Aircraft and battery performance is subject to environmental factors such as air density and temperature. Be very careful when 

flying 14700 feet (4500 meters) or more above sea level as battery and aircraft performance may be reduced. 

6. The Inspire 1 cannot operate in P mode or use GPS at polar latitudes. It only can fly in A TTl mode and use the Vision Positioning System.

1. Fly in Open Areas: Nways fly in locations that are free and clear of buildings, trees, power lines, and other obstacles. Do not fly above 

or near peOple or animals. 

2. Maintain Control at All Times: Even when using DJI autopilot functions such as Auto-Takeoff, Auto-Landing, and Auto-Return to 

Home, always keep your hands on the Remote Controller and maintain control of your aircraft when it is in flight. 

3. Maintain Une of Sight Keep your aircraft In sight at all times, and avoid flying behind buildings or other obstacles that may block your 1/ew. 

4. Monitor Your Altitude: For the safety of full-sized aircraft and other air traffic, always fly at altitudes less than 400 feet (120 meters) 

above ground level, or in line with your local laws and regulations. 

Visit http://flysafe.dji.com/no-fly for more Information on critical safety features such as 

No-Ay Zones. ~­

- • Calibrating the Compass: 

Make sure to calibrate the compass at every new flight location. The compass is very sensitive to electromagnetic interference, which 

can cause abnormal compass data, leading to poor flight performance or even failure. Regular calibration is required for optimal 

performance. 

1. DO NOT calibrate your compass where there Is a chance of strong magnetic interference, such as magnetite, parking structures, and 

steel reinforcements underground. 

2. DO NOT carry ferromagnetic materials with you during calibration such as keys or cellular phones. 

3. DO NOT calibrate beside massive metal objects. 

4. If the Aircraft Status Indicators are showing solid red, then try to calibrate again. If they are blinking red and yellow alternately after 

placing the aircraft on the ground, the compass has detected magnetic interference. Change your location. 

• Environmental Considerations: 

1. Do not fly in severe weather conditions. This includes high winds (speeds of 22 mph or 1 0 m/s or more), snow, rain, and fog. 

2. Only fly in open areas. Tall buildings and steel structures may affect the accuracy of the on-board compass and GPS signal. 

3. Avoid obstacles, crowds, high-voltage power lines, trees, and bodies of water. 

4. Minimize electromagnetic interference by avoiding areas with high levels of electromagnetism, Including mobile phone base stations, 

radio transmission towers, or Wi-Fi hotspots. 

5. Aircraft and battery performance are subject to environmental factors such as air density and temperature. Be very careful when 

flying 19,600 feet (6 km) or more above sea level, as battery and aircraft performance may not be at peak efficiency. 

6. The Phantom 3 Professional cannot operate in P Mode or use GPS at polar latitudes. Only AlTI Mode and the Vision Positioning 

system will be operational. 

• P Mode: 

In this mode, the Phantom 3 Professional can use GPS and the Vlsion 

Positioning system, allowing it to hover accurately in position Indoors 

and out. When GPS is available, a Home Point will be locked so that the 

Phantom 3 Professional can Return to Home if the Remote Controller 

signal is lost. 

~ 

v 

To enable P Mode, toggle the Right Mode Switch 

to the P position. 

There are three states in P mode: 

P"GPS: GPS works best when outdoors and In a wide open area. Your 

Phantom 3 Professional uses GPS to hover in place when there is a 

strong GPS signal. 

P-OPTI: If GPS is not available, the aircraft can use the VISion Positioning 

system to hover accurately. 

P-Am: Neither GPS nor the Vision Positioning system are available. 

The aircraft will only use its barometer for altitude and other on-board 

sensors for attitude stabilization. 

Note that the Vision Positioning system may not work properly when 

the Phantom 3 Professional is flying over water, over surfaces without 

a clear pattern, or in a low-light environment.

When there is a strong GPS signal, the aircraft will be able to 

record a Home Point and return to that Home Point when 

required. The Home Point location Is recorded when the GPS 

signal icon in the DJI Pilot app Is either yellow or green. 

The aircraft will return to the Home Point automatically in the 

following scenarios (all require a strong GPS signal): 

Smart RTH: When the RTH button on the Remote Controller 

or in the DJI Pilot app is pressed. 

Low-Battery RTH: A notification will appear in the DJI Pilot 

app requesting the pilot to take action when the battery level 

falls under a certain level. 

Failsafe RTH: When the Remote Controller's signal is lost . 

• While returning to the Home Point, the aircraft's altitude can be adjusted to avoid obstacles. Tall buildings may affect the Remote 

Controller's signal. The Failsafe Retum to Home procedure will be triggered if the signal is lost. Be sure to fly higher than any nearby 

buildings to avoid crashing.

1 Introduction 

We designed Solo to be the perfect aerial-video tool. It's powerful, simple and reliable with intuitive Smart Shots 

inspired by our favorite cinema pilots. With Solo, you don't need a professional camera crew, you can get the 

perfect shot every time. We're excited to share our passion with you and help you see your world from a new 

perspective. Join us in capturing the next evolution of creative videography. 

1.1 System Overview 

The Solo system includes Solo, the controller, the "3DR Solo" app, and you. As the operator, you interact with the 

controller and app on the ground, and the controller communicates with Solo during flight. 

1.1.1 Solo 

Solo is a small unmanned aerial vehicle powered by four motors and four propellers. Solo's onboard computers 

control navigation, attitude, and communications in flight while sending real-time telemetry and video output and 

receiving control inputs over the 3DR Link secure Wi-Fi network. Solo is optimized for capturing aerial video using a 

GoPro® HERO camera. 

1.1.2 Controller 

The controller provides control mechanisms and displays in-flight data on a full-color screen. Using twin longrange antennas, the controller acts as the central hub for all communication on the 3DR Link network, receiving all 

communications from Solo and the app, forwarding telemetry outputs to the app, and managing the transmission of 

all control inputs to Solo. 

1.1.3 App 

The "3DR Solo" app outputs a live video stream from an onboard GoPro® camera to an Android or iOS device. The

Options 

The following operating parameters apply to Solo. Always operate Solo within these parameters. Solo's performance 

and behaviors are not guaranteed when conditions violate the parameters listed below. 

Rgure 1.4.1 0.1 : Solo Operating Parameters 

*Flight time varies with payload, wind conditions, elevation, temperature, humidity, flying style, 

and pilot skill. Listed flight time applies to elevations less than 2,000 ft above sea level. 

**See Section 7.7 to adjust maximum altitude. 

***Depending on environmental conditions 

****This top speed corresponds to Solo when operating in Fly mode. Maximum speeds for advanced 

modes may vary, see Section 7.1 for more information.

1.5 Autopilot 

Solo uses a Pixhawk 2 autopilot running ArduPilot Copter software. ArduPilot is open-source flight control based on 

the MAVIink communication protocol. Pixhawk 2 runs an ARM Cortex-M4 STM32F427 processor with 2 MB of flash 

memory and 256 KB of RAM. Combined with an array of CAN, 12C, SPI, PWM, and UART interfaces, Pixhawk 2 

uses a suite of onboard sensors to calculate Solo's orientation and motion in flight. This data is input into ArduPilot's 

inertial navigation and position estimation algorithms and combined with control inputs to send commands to Solo's 

propulsion system. 

1.6 Propulsion 

Solo uses four brushless 880 K. motors and four self-tightening propellers for propulsion. For control and 

aerodynamic efficiency, two motors spin clockwise and two motors spin counterclockwise. Navigation in the air is 

achieved by mixing propulsion of the four motors to actuate flight control along the roll, pitch, and yaw axes. 

Each of the four motors is numbered by the marking on the arm. These numbers correspond to the autopilot 

calculations for these commands and are used for indicating motor replacement procedures. Each motor is 

controlled by an ESC (Electronic Speed Controller) that regulates the rotation of the motors to achieve the speed 

commanded by the autopilot.

3 Safety 

The following best practices will help ensure safe, successful flights and help reduce the risk of accident and serious 

injury. Always fly under adult supervision and with your full attention at all times. Do not fly under the influence of 

drugs or alcohol or when your ability to operate Solo safely is impaired. Use your common sense to avoid unsafe 

situations and always operate Solo responsibly. 

3.1 Location 

Don't fly Solo indoors. Always fly outside in clear, open areas at a safe distance from yourself, other people, power 

lines, animals, vehicles, trees, and buildings. When flying in areas with potential hazards, maintain 100 feet (30m) 

from any people, vehicles, or structures. As the operator, you are responsible for navigating Solo to avoid obstacles, 

including during Smart Shots. 

Don't fly within 5 miles of an airport or within any airspace restricted by your local, state, or national airspace 

authority. As the operator, you are responsible for knowing and understanding the regulations that govern small 

unmanned aircraft like Solo in your jurisdiction. 

3.2 Environmental Awareness 

Don't fly Solo in extreme weather conditions such as rain, high winds, snow, or fog. Extreme weather conditions can 

permanently damage Solo or cause instability in flight. 

Before flying, determine the boundaries of the safe flying area at your location. Be aware of any risks, including 

bodies of water, structures, trees, power lines, etc, and designate a few areas where you can land Solo in case of 

an unsafe situation. Throughout your flight, be prepared to recover Solo manually or use an emergency procedure if 

Solo flies outside the safe flying area. 

3.3 Visual Line of Sight 

Always fly Solo within your visual line of sight. Don't let Solo get so far away from you that you cannot see its 

orientation or so that any physical obstructions block your view of Solo. 

3.4 Flight School 

If you're new to flying, review the video tutorials in the Flight School area of the app before your first flight. Flight 

School provides useful tips for learning to operate Solo safely and correctly. 

Figure 3.4.5.1: App Flight School 15 
3.5 Propellers 

To avoid hazardous contact with Solo's high-speed propellers, always power off Solo before handling Solo or 

the propellers. When prompted to start motors before takeoff, always ensure that the propellers are clear of any 

obstructions and at least 20 feet away from any people, animals, or property before activating. Do not touch moving 

propellers or approach Solo while the propellers are spinning. 

After landing or returning home, Solo will automatically detect the landing and stop the motors. Do not approach 

Solo until the propellers stop spinning, and always power off Solo before picking it up. 

3.6 GPS 

Solo requires an active GPS signal for flight. After powering on, Solo can take up to 5 minutes to acquire a strong 

GPS lock. Always choose a flying location with a clear view of the sky to improve GPS signal strength. The following 

requirements define a GPS lock: 

• Reported horizontal position accuracy 

• Reported speed accuracy 

• Number of satellites 

• Difference between GPS and inertial navigation vertical velocity 

<16ft. (5 m) 

< 2 mph (1 m/s) 

~6 

< 2 mph (1 m/s) 

If satellite coverage drops beneath a reliable threshold during flight, Solo will automatically switch to FL Y:Manual 

mode. This mode does not provide the flight stabilizing GPS functionality, but it still allows you to retain control of 

Solo. 

3.7 Home Position 

Solo's home position is the latitude and longitude coordinates of the launch point used by the autopilot as the 

end point of a return-home command. The autopilot saves the home position at the location where the motors are 

started only after achieving GPS lock. The location of the home position depends on GPS signal strength and is 

usually within 1 to 2 meters of accuracy. Always take off from an open location with a clear path for Solo to return 

home safely. For home position safety in advanced mode, see Section 7.4. 

3.8 Altitude Limit 

Always fly at appropriate altitudes for your flying location and local regulations. Solo cannot avoid obstacles on its 

own, so always select altitudes that avoid any obstacles, such as trees, buildings, and power lines. 

Solo includes a safety fence enabled by default at 150ft. (46 m). If Solo reaches the altitude limit, Solo will stop 

ascending and limit throttle input to stay below the altitude limit. FAA regulations mandate a maximum altitude of 

400 ft. to avoid potential conflicts with manned aircraft and represents a safe line-of-sight altitude. 

16 
3.9 Emergency Procedures 

If you experience a problem in flight, use one of the following emergency procedures to stop Solo, end your flight, or 

shut off the motors. 

3.9.1 Pause 

The controller's Pause button allows you to stop Solo mid-air. Solo will hover at the paused location until given 

another command. Use the Pause button to stop Solo from hitting an obstacle or to re-orient Solo for navigation. 

Press Pause during Return Home or Land to pause Solo and stop the landing. Pause is available only with GPS 

lock. 

3.9.2 Regain Manual Control 

Keep the controller easily accessible at all times during flight, including during Smart Shots, and be prepared to 

regain manual control at any time. To return to stam;lard flight during Smart Shots, Return Home, or Land, press the 

Fly button. · 

3.9.3 Return Home 

If Solo acquired GPS lock prior to takeoff, press the controller's Home button to return Solo to the launch point 

and land. Use return home after receiving a low battery notification or to end your flight easily. Solo will not avoid 

obstacles while returning home; always verify that the return path is clear before activating Return Home. 

3.9.4 Land 

To land Solo at its current position, press and hold the Fly button. Lift the throttle at any time to exit the landing 

procedure. If Solo does not have GPS lock, there will be no automatic positioning as Solo descends, and drifting 

may occur depending on environmental conditions. 

3.9.5 Motor Shutoff 

In the event that Solo's motors do not stop after landing or for an emergency in-flight kill switch, Solo includes· 

an emergency motor shutoff procedure. To shut off the motors at any time, either in flight or on the ground, hold 

the A, 8, and Pause buttons at the same time. An initial screen will appear on the controller to confirm the shutoff 

command; continue to hold A, 8, and Pause buttons to activate motor shutoff. Use the emergency motor shutoff 

only as a last resort. 

Rgure 3.9.5.1: Controller- Motor Shutoff 

17 
3.10 Flight Battery 

Use caution when handling the Solo Smart Battery; lithium polymer batteries can cause a fire if handled incorrectly. 

Never alter, puncture, throw, bend, or impact the battery. Keep the battery away from liquids, fire, microwaves, and 

other hazardous or combustible materials. Don't expose the battery to extreme temperatures. If the battery is hot to 

the touch, wait for it to cool before using or charging. 

Inspect the battery before and after each flight. It is possible for the battery to be damaged in shipping, use or 

charging. If you notice any abnormal features such as damage to the exterior shell, swelling, deformation of the 

battery, abnormal smell, leakage, or other unexpected behavior, do not use the battery! These can be signs of 

serious damage that can cause the battery to catch fire. To prevent a hazard in case of fire or explosion, disconnect 

the battery, and place the battery in a safe area outside of any buildings or vehicles and away from flammable 

materials. Do not dispose of the battery in the trash; dispose of the battery at local battery recycling center as soon 

as possible. In the US and Canada, visit call2recycle.org to find a location. 

For long term storage, store the battery in an 64° F to 82° F environment, between 45-85% relative humidity 

and with 50% charge. Always make sure to store the battery in a place where it won't be exposed to extreme 

temperatures or direct sunlight. 

3.11 Controller 

The controller's rechargeable lithium ion (Li-ion) battery is housed inside the controller, accessible by the battery 

door on the back of the controller. The controller battery is pre-attached to the controller, and shouldn't be 

disconnected unless: 

• You plan to store the controller for over three months without using it. In this case, disconnect the battery 

from the controller and leave the battery inside the controller to store it. 

• You need to replace or upgrade the controller battery. Upgraded controller batteries with double the 

capacity are available from store.3dr.com or an authorized retailer. In the case where you need to store the 

extra controller battery, store it in location where it will not come into contact with metal objects or other 

batteries. If the battery's connector comes into contact with a metal object, it can short circuit the battery and 

cause a fire. 

Keep the controller away from liquids, fire, microwaves, and other hazardous or combustible materials. Don't 

expose the controller to extreme temperatures. If the controller is hot to the touch, wait for it to cool before using 

or charging. Perform periodic visual inspections of the controller battery to check for any damage, and handle the 

controller battery using the same safety precautions as the flight battery. 

3.12 Antenna Configuration 

For the strongest connection to Solo, position the antennas down and away from the controller so they are 

approximately perpendicular with Solo in flight, and tilt each antenna out and away from one another at a 20° angle.

6 Alerts 

The following alerts will appear on the controller in the event of a preflight or in flight error. Always monitor the 

controller for alerts and perform the recommended actions. 

6.1 Preflight Errors 

Before starting the motors, Solo runs a series of automatic checks to ensure that the system is ready for flight. 

6.1.1 Calibration 

The following errors indicate that a preflight check is in progress: altitude calibrating, calibrating solo, and calibrating 

compass. Please wait for the error to clear before continuing. 

Figure 6.1.1 .1 : Controller - Calibration in Progress Alerts 

If Solo is not placed on a level surface, you will receive the following alert to move Solo to a level surface for takeoff. 

Figure 6.1.1.2: Controller - Uneven Surface Alert 

If Solo requires manual calibration, the following alert messages show the displays for compass and level 

calibrations. Refer to Section 9.2 for compass and level calibration instructions. 

Figure 6.1.1.3: Controller - Re-Calibration Required Alerts 

In the case of a calibration or sensor error during startup, restart Solo to clear the following alerts. 

32 
Figure 6.1.1.4: Controller - Calibration Error Alert 

6.1.2 Service Alerts 

The following alerts indicate a system error that requires service. Use the app to submit a trouble ticket with 3DR 

Support or contact an authorized Solo Service Center to service Solq and clear the alert. A control stick error can 

occur either in flight or before takeoff. If the control stick error is received in flight, Solo will return home and land. 

Figure 6.1.2.1 : Controller - Service Alerts 

6.2 In-Flight Errors 

During flight, the controller monitors Solo's GPS signal, controller signal, flight battery level, and controller battery 

level. 

6.2.1 Altitude Limit 

If Solo reaches the altitude limit during flight, it will maintain and not exceed that altitude and the controller will 

display the following alert. 

Figure 6.2.1.1: Controller - Altitude Umit Alert 

6.2.2 App Connection 

The controller will display the following banner-style alerts in the event that the Solo app is connected to or 

disconnected from Solo. We recommend having an active connection to the Solo app at all times during flight. Refer 

to Section 2.6 for connecting to Solo Wi-Fi with the app. Solo will not return home if the connection to the app in 

lost during flight. 

33 
Figure 6.2.2.1: Controller - App Connection Alerts 

6.2.3 Controller Signal Alerts 

Flying behind solid objects, like buildings and trees, blocks communication signals between Solo and the controller. 

Always maintain visual contact with Solo to ensure that the signal is unobstructed. Cell phone towers and nearby 

Wi-Fi signals can cause interference with the communication system and decrease its range. Avoid flying in 

populated areas to avoid sources of interference. 

If the controller becomes unpaired from Solo during flight, the controller will display the following alert and Solo will 

Return Home. See Section 9.3 for pairing instructions. 

Figure 6.2.3.1: Controller - Controller Disconnected Alert 

If the signal between Solo and the controller is lost during flight, the controller will display the controller signal lost 

alert and Solo will Return Home. If signal is recovered while returning home, the controller will display the signal 

recovered alert and provide the option to regain manual control by pressing the Fly button. 

Figure 6.2.3.2: Controller - Controller Signal Alerts 

6.2.4 GPS Signal Alerts 

If GPS is lost during flight, Solo will switch into Fly: Manual. In the event of a loss of GPS, we recommend landing 

Solo and waiting to acquire GPS lock before taking off again. 

In Fly: Manual, Solo uses the same joystick controls as in standard flight (displayed as "Fly"), but it does not include 

any GPS positioning. Therefore, in Fly: Manual, Solo will not hold its position when the right stick is released, and 

you must maintain close control over roll, pitch, and yaw. Without GPS, Pause, Return Home, and Smart Shots are 

not available. During Land, Solo will not be able to maintain position due to the lack of GPS positioning and will drift 

according to wind and other environmental conditions. If another alert occurs while Solo is in Fly: Manual, Solo will 

not be able to Return Home and will instead initiate a non-positioned landing at the current location. 

If GPS is recovered in flight, Solo will switch from Fly: Manual to standard flight (Fly), and GPS positioning will 

activate. The following displays show (from left to right) the GPS lost alert, Solo in Fly: Manual, and GPS recovered 

alert. Always choose a location with a clear view of the sky to improve GPS signal strength. 

34 
Figure 6.2.4.1: Controller - GPS Signal Alerts 

6.2.5 Flight Battery Alerts 

The controller monitors the Solo battery during flight and provides alerts when the battery reaches critical levels. At 

25% and 10% power remaining, the controller will provide a land-soon alert recommending that you end your flight 

to prevent an automatic landing. 

Rgure 6.2.5.1: Controller- Low Battery Alerts 

If the battery reaches 5%, Solo will Return Home to prevent a crash. After landing, turn off Solo immediately; if the 

battery level reaches 0% at any time, irreversible damage will occur and the battery should be recycled.

7 Advanced Settings 

This section provides instructions for accessing and using Solo's advanced features and settings. 

7.1 Advanced Flight Modes 

Are you a quadcopter pro? We designed Solo to be simple and reliable, but also really fun to fly. Solo includes five 

advanced flight modes: FL Y:Manual, stabilize, aero, sport, and drift. 

7.1.1 Fly:Manual 

Fly: Manual mode is a version of standard flight without GPS lock. In Fly:Manual, the throttle stick controls altitude 

the same way as standard flight {Fly mode). However, Fly:Manual includes no GPS positioning so that, when 

you release the right stick, Solo will not hold its position; it will drift according to wind conditions and existing 

momentum. When flying in Fly: Manual, make constant adjustment to the right stick to control Solo's position and 

use the left stick to maintain Solo's orientation. 

7.1.2 Stabilize 

Stabilize mode provides full manual control without autopilot assistance. In stabilize, the autopilot regulates Solo's 

roll and pitch angles so that Solo returns to level when you release the right stick. The throttle stick controls power 

and acceleration directly; it does not correspond to altitude. Stabilize requires fine-tuned control of both the left and 

right sticks to fly Solo. Stabilize does not require GPS lock. 

7.1.3 Drift 

Drift modes requires GPS lock and provides a plane-like flying experience. Drift is ideal for navigating Solo using 

the video feed. This is known as first-person view {FPV) and provides an immersive flying experience. In drift, Solo 

combines roll, pitch, and yaw onto the controller's right stick. To navigate Solo in drift, move the right stick to initiate 

a coordinated turn in that direction. Releasing the right stick will cause Solo to drift to a stop over a two-second 

period. Solo does not automatically control altitude in drift, and will require constant adjustments to the throttle stick 

when flying in drift. 

7.1.4 Aero 

Aero is the most advanced of Solo's flight modes. It provides unrestricted control over Solo's roll and pitch angles. 

Aero is intended for performing aerial acrobatics, flips, and maneuvers requiring extreme angles. There is no altitude 

or position assistance in aero, so be prepared to make constant adjustment to both sticks. Aero is a copter-frame 

oriented mode, meaning that, in aero, Solo will always respond to controls relative to its own orientation. Aero does 

not require GPS lock.. 

36 
7.1.5 Sport 

Sport mode in a modified version of aero that includes altitude assistance and earth-frame orientation. With 

altitude assistance, the throttle stick behaves the same in sport as it does in standard flight (Fly mode). Earth-.frame 

orientation differs from copter-frame orientation in that the direction of yaw rotation is in relation to the earth instead 

of in relation to the copter itself. For example, if Solo is pitched forward in sport mode and left yaw is applied, 

Solo will maintain the same pitch angle and rotate around the vertical axis. As opposed to in aero's copter-frame 

orientation, in which, in the same situation, Solo will perform a cartwheel. Sport does not require GPS lock. 

7.2 Enabling Advanced Flight Modes 

To unlock Solo's advanced flight modes, use the app to select Advanced Settings from the Settings menu. Toggle 

the Enable Advanced Flight Modes option to gain access to Solo's advanced modes.

7.4 Home Position Safety 

Fly:Manual, stabilize, aero, and sport modes do not require GPS lock. To take off without GPS lock, Solo must be 

set to one of these modes. Without an active GPS signal, Return Home, Pause, and Smart Shots will be disabled. 

If you choose to take off without GPS lock, Solo will not save a home position at the launch point. If Solo acquires 

GPS lock mid-flight, the autopilot will save a home position at that location. To prevent a potentially unsafe situation, 

do not use Return Home if Solo did not acquire GPS prior to takeoff. 

37 
7.5 Performance Adjustment 

The Solo app includes options to adjust Solo's performance to suit your flying style. To access the performance 

sliders, select Performance from the Solo menu. The flight slider controls how fast Solo flies and how resJ:>onsive 

it is to controls. The camera pan slider regulates the speed that Solo rotates. Move the slider towards the turtle for 

slower, more cushioned movement, or move the slider towards the rabbit for faster, more responsive movement.

9.7 Factory Reset 

Performing a factory reset restores Solo and the controller to their state prior to the first flight update. Use a factory 

reset if you forget your Solo Wi-Fi password or need to restore Solo's factory settings. 

9.7.1 Controller 

To reset the controller, start with the controller powered off. Hold the power and Fly buttons simultaneously until 

you see the controller-updating display (Figure 2.6.4.7). The controller will restart, taking up to 5 minutes, then 

display the green checkmark and prompt you to press A to continue (Figure 2.6.4.9). When the reset procedures 

is complete, the controller will display the preflight-update display (Figure 2.6.4.1). Complete the update process 

described in Section 2.6.4 to prepare Solo for flight. 

9.7.2 Solo 

As part of the reset procedure for Solo, Solo will be un-paired from the controller. Start by powering off Solo. Use 

a paperclip or similar tool to press and hold Solo's pair button (Figure 8.3.2.1) while powering on Solo. Release the 

pair button after you see the internal LED adjescent to the Pair button start rapidly flashing orange. This signals the 

factory reset procedure is now underway. 

After a few minutes, Solo's main LEDs will start flashing different colors in a rotating pattern as the reset nears 

completion. Once Solo emits an initialization tone, the factory reset is complete, and Solo is now ready to be paired 

with the controller; follow the instructions in Section 9.3 to pair Solo with the controller. If the rotating light pattern 

stops, but Solo doesn't emit an initialization tone, power off and power on Solo and follow the pairing instructions in 

Section 9.3.
