4.3 Falsification, Reproduction, or Alteration. The FAA relies on information provided by owners and remote pilots of small UAS when it authorizes operations or when it has to make a compliance determination. Accordingly, the United States government may take appropriate action against a small UAS owner, operator, remote PIC, applicant for a DOC, or anyone else who fraudulently or knowingly provides false records or reports, or otherwise reproduces or alters any records, reports, or other information for fraudulent purposes. Such action could include the FAA’s imposition of civil sanctions and the suspension or revocation of a certificate or waiver (§ 107.5).

4.4 Accident Reporting. The remote PIC of the small unmanned aircraft is required to report an accident to the FAA within 10 days if it meets any of the following thresholds:

1. At least serious injury to any person or any loss of consciousness. A serious injury is an injury that qualifies as Level 3 or higher on the Abbreviated Injury Scale (AIS) of the Association for the Advancement of Automotive Medicine (AAAM). The AIS is an anatomical scoring system that provides a means of ranking the severity of an injury and is widely used by emergency medical personnel. The FAA currently uses serious injury (AIS Level 3) as an injury threshold in other FAA regulations.

AIS 3 Example: A person requires hospitalization, but the injury can fully heal (including, but not limited to, head trauma, broken bone(s), or laceration(s) to the skin that requires suturing).

2. Damage to any property, other than the small unmanned aircraft, if the cost is greater than $500 to repair or replace the property (whichever is lower).

Example: A small unmanned aircraft damages a property with a fair market value of $200, and it would cost $600 to repair the damage. Because the fair

4-6 market value is below $500, this accident is not required to be reported.

Similarly, if the aircraft causes $200 worth of damage to property with a fair market value of $600, that accident is also not required to be reported because the repair cost is below $500 (§ 107.9).

4.4.1 S ubmitting the Report . The accident report must be made within 10 calendar-days of the operation that created the injury or damage. The report may be submitted to the appropriate FAA Regional Operations Center (ROC) electronically or by telephone.

Electronic reporting can be completed at https://www.faa.gov/uas/. To make a report by phone, see Figure 4-1, FAA Regional Operations Centers Telephone List. Reports may also be made to the responsible Flight Standards office (refer to https ://www.faa.gov/about/office_org/field_offices/fsdo/ ). The report should include the following information:

1. S mall UAS remote PIC’s name and contact information;

2. Small UAS remote PIC’s FAA airman certificate number;

3. Small UAS registration number issued to the aircraft (FAA registration number);

4. Location of the accident;

5. Date of the accident;

6. Local time of the accident;

7. Whether any serious injury or fatality occurred;

8. Property damaged and extent of damage, if any or known; and

9. Description of what happened.

4.4.2 National Transportation Safety Board (NTSB) Reporting. In addition to the report submitted to the ROC, and in accordance with the criteria established by the NTSB, certain small unmanned aircraft accidents must also be reported to the NTSB. NTSB’s regulations, codified at 49 CFR part 830, require immediate notification when an aircraft accident occurs. NTSB regulations define an “unmanned aircraft accident” as an occurrence associated with the operation of any public or civil UAS that takes place between the time that the system is activated with the purpose of flight and the time that the system is deactivated at the conclusion of its mission, in which any person suffers death or serious injury, or the aircraft has a maximum gross takeoff weight of 300 pounds or greater and sustains substantial damage. NTSB regulations contain specific definitions for “serious injury” and “substantial damage” (49 CFR part 830, § 830.2). For more information, visit https://www.ntsb.gov.

5-1 CHAPTER 5. PART 107 SUBPART B, OPERATING RULES (SMALL UAS)

5.1 Applicability. This chapter provides guidance regarding small unmanned aircraft operating limitations and the responsibilities of the remote pilot in command (PIC), person manipulating the controls, visual observer (VO), and anyone else who may directly participate in the small UAS operation. A person is a direct participant in the small UAS operation if their involvement is necessary for the safe operation of the small UAS.

5.2 Aircraft Operation. Just like a manned-aircraft PIC, the remote PIC of a small unmanned aircraft is directly responsible for and is the final authority for the safe operation of the small unmanned aircraft (§ 107.19). Additionally, a person manipulating the controls (who is not the remote PIC) can participate in flight operations under certain conditions. It is important to note that a person may not operate or act as a remote PIC or VO in the operation of more than one small unmanned aircraft at the same time (§ 107.35). The following items describe the requirements for both a remote PIC and a person manipulating the controls.

5.2.1 Remote PIC. A person acting as a remote PIC of a small UAS under part 107 must obtain a Remote Pilot Certificate with a small UAS rating issued by the FAA prior to small UAS operation (§ 107.12). The remote PIC must have, in that person’s physical possession and readily accessible, this certificate and personal identification during flight operations (§§ 107.7 and 107.67(b)(1) through (3)). Guidance regarding remote pilot certification is found in Chapter 6, Part 107 Subpart C, Remote Pilot Certification.

5.2.1.1 Part 107 permits transfer of control of a small UAS between certificated remote pilots. Two or more certificated remote pilots transferring operational control (i.e., the remote PIC designation) to each other may do so only if they are both capable of maintaining Visual Line of Sight (VLOS) of the small unmanned aircraft without loss of control (LOC). One remote pilot may be designated the remote PIC at the beginning of the operation, and at some point in the operation another remote pilot may take over as remote PIC by positively communicating the transfer of control. The remote PIC assuming control of the small UAS maintains responsibility for the safe operation of the small UAS.

5.2.2 Person Manipulating the Flight Controls. A person who does not hold a Remote Pilot Certificate or a remote pilot who has not met the recurrent training requirements of part 107 may operate the small UAS under part 107, as long as they are directly supervised by a remote PIC and the remote PIC has the ability to take immediate, direct control of the small UAS. This ability is necessary to ensure the remote PIC can quickly address any hazardous situation. The ability of the remote PIC to take over the flight controls immediately could be achieved by using a number of different methods. The operation could involve a “buddy box” type system that uses two control stations (CS):

one for the person manipulating the flight controls and one for the remote PIC that allows the remote PIC to override the other CS and immediately take direct control of the small unmanned aircraft (§ 107.19). Another method could involve the remote PIC standing

5-2 close enough to the person manipulating the flight controls so that they would be able to physically take over the CS from the other person. Another method could employ the use of an automation system where the remote PIC could immediately engage that system to put the small unmanned aircraft in a pre-programmed “safe” mode such as a hover, a holding pattern, or “return home.”

5.2.3 A utomated Operations. An automated operation is generally considered an operation in which the remote pilot inputs a flight plan into the CS, which sends the flight plan to the autopilot on board the small unmanned aircraft. During automated flight, flight control inputs are made by components on board the aircraft, not from a CS. If the remote PIC loses the control link to the small unmanned aircraft, the aircraft would continue to fly the programmed mission/return home to land. During automated flight, the remote PIC must have the ability to change routing/altitude or command the aircraft to land immediately.

The ability to direct the small unmanned aircraft may be through manual manipulation of the flight controls or through commands using automation.

5.2.3.1 Th e remote PIC must retain the ability to direct the small unmanned aircraft to ensure compliance with the requirements of part 107. The remote PIC may transmit a command for the automated aircraft to climb, descend, land now, proceed to a new waypoint, enter an orbit pattern, or return to home. Any of these methods may be used to avoid a hazard or give right-of-way.

5.2.3.2 The use of automation does not allow a person to operate more than one small unmanned aircraft simultaneously (§ 107.35).

5.3 Aeronautical Decision-Making (ADM) and Crew Resource Management (CRM).

ADM is a systematic approach to the mental process used by pilots to determine consistently the best course of action in response to a given set of circumstances. A remote PIC uses many different resources to safely operate a small unmanned aircraft and needs to be able to manage these resources effectively. CRM is a component of ADM, in which the pilot of a small unmanned aircraft makes effective use of all available resources: human resources, hardware, and information. Many remote pilots operating under part 107 may use a VO, oversee other persons manipulating the controls of the small UAS, or any other person with whom the remote PIC may interact to ensure safe operations. Therefore, a remote PIC must be able to function in a team environment and maximize team performance. This skill set includes situational awareness, proper allocation of tasks to individuals, avoidance of work overloads for themselves and in others, and effectively communicating with other members of the crew, such as VOs and persons manipulating the controls of a small unmanned aircraft. Appendix A, Risk Assessment Tools, contains expanded information on ADM and CRM, as well as sample risk assessment tools to aid in identifying hazards and mitigating risks.

5.4 A ircraft Registration. A small unmanned aircraft must be registered, in accordance with part 47 or part 48, prior to operating under part 107. Part 48 is the regulation that establishes the streamlined online registration option for small unmanned aircraft that will be operated only within the territorial limits of the United States. The online registration website is https://faadronezone.faa.gov/. Guidance regarding small

5-3 unmanned aircraft registration and marking may be found at https://www.faa.gov/licenses_certificates/aircraft_certification/aircraft_registry/.

Alternatively, small unmanned aircraft owners or operators can elect to register under part 47 in the same manner as manned aircraft.

5.4.1 Registration and Permit for Foreign-Owned and Operated Sm all UAS. If small UAS operations involve the use of foreign civil aircraft, the operator would need to obtain a Foreign Aircraft Permit pursuant to 14 CFR part 375, as described in § 375.41, before conducting any commercial air operations under this authority. Foreign civil aircraft means (a) an aircraft of foreign registry that is not part of the armed forces of a foreign nation, or (b) a U.S.-registered aircraft owned, controlled, or operated by persons who are not citizens or permanent residents of the United States. Application instructions are specified in § 375.43. Applications should be submitted by electronic mail to the Department of Transportation (DOT) Office of International Aviation, Foreign Air Carrier Licensing Division at https://cms.dot.gov/policy/ aviation-policy/licensing/for eign-carriers. Foreign-owned and operated small UAS must be registered, as provided for under part 47 or part 48, including submission of an Affidavit of Ownership for Unmanned Aircraft, if necessary. Additional information can be obtained at https://www.faa.gov/licenses_certificates/aircraft_certification/aircraft_registry/UA/.

(Refer to Title 49 of the United States Code (49 U.S.C.) § 44101(b)(1) for exceptions.)

5.5 S mall U nmanned Aircraft Maintenance, Inspections, and Condition for Safe Operation. A small unmanned aircraft must be maintained in a condition for safe operation. Prior to flight, the remote PIC is responsible for conducting a check of the small unmanned aircraft to verify it is actually in a condition for safe operation (§ 107.15). Guidance regarding how to determine that a small unmanned aircraft is in a condition for safe operation is found in Chapter 7, Sm all U nmanned Aircraft Maintenance and Inspection.

5.6 M edical Condition. Being able to operate the small unmanned aircraft safely relies on, among other things, the physical and mental capabilities of the remote PIC, person manipulating the controls, VO, and any other direct participant in the small UAS operation. Though the person manipulating the controls of a small unmanned aircraft and VO are not required to obtain an airman medical certificate, they cannot participate in the operation of a small UAS if they know or have reason to know that they have a physical or mental condition that could interfere with the safe operation of the small UAS (§ 107.17).

5.6.1 P hysical or Mental Incapacitations. Obvious examples of physical or mental incapacitations that could render a remote PIC, person manipulating the controls, or VO incapable of performing their small UAS operational duties include, but are not limited to, such things as:

1. T he temporary or permanent loss of the dexterity necessary to operate the CS to control the small unmanned aircraft safely.

2. The inability to maintain the required “see and avoid” vigilance due to blurred vision.

5-4

3. The inability to maintain proper situational awareness of the small unmanned aircraft operations due to illness and/or medication(s), such as after taking medications that caution against driving or operating heavy machinery.

4. A debilitating physical condition, such as a migraine headache or moderate or severe body ache(s) or pain(s) that would render the remote PIC, person manipulating the controls, or VO unable to perform small UAS operational duties.

5. A hearing or speaking impairment that would inhibit the remote PIC, person manipulating the controls, or VO from effectively communicating with each other. In such a situation, the remote PIC must ensure they implement an alternative means of effective communication. For example, a person who is hearing impaired may be able to use sign language to communicate effectively.

5.7 Civil Twilight and Operations at Night. Night is defined in § 1.1 as the time between the end of evening civil twilight and the beginning of morning civil twilight, as published in The Air Almanac, converted to local time. In the continental United States, evening civil twilight is the period of sunset until 30 minutes after sunset and morning civil twilight is the period of 30 minutes prior to sunrise until sunrise. In Alaska, the definition of civil twilight differs and is described in The Air Almanac. The Air Almanac provides tables to determine sunrise and sunset at various latitudes. These tables can also be downloaded from the Naval Observatory and customized for a particular location. The link for the Naval Observatory is https://www.usno.navy.mil/search?SearchableText=air+ almanac+.

5.7.1 Civil Twilight Operations. When small UAS operations occur during civil twilight, the small unmanned aircraft must be equipped with anti-collision lighting visible for at least 3 statute miles (sm). However, the remote PIC may reduce the visible distance of the lighting to less than 3 sm during flight if they have determined that it would be in the interest of safety to do so. For more information on this determination, see paragraph 5.7.2.2.

5.7.2 Operations at Night. Small UAS operations at night may occur only under the two risk mitigation measures listed in § 107.29. First, the remote PIC must have completed either an initial knowledge test or recurrent training that have been updated to include night operations. Second, the small unmanned aircraft must have lighted anti-collision lighting that is visible for at least 3 sm. The remote pilot may rely upon manufacturer statements indicating the anti-collision lighting is visible for 3 sm. However, the remote pilot ultimately remains responsible for verifying that anti-collision lighting is operational, visible for 3 sm, and has a flash rate sufficient to avoid a collision at the operating location.

5.7.2.1 A certificated remote pilot receives night operations privileges and may operate at night only after completing either a knowledge test that contains questions on night physiology and night visual illusions, or through completion of recurrent training. The recurrent training contains the topics of night physiology and night visual illusions. Chapter 6 provides a detailed explanation of both paths for night operations privileges.

5-5

5.7.2.2 As is the case for civil twilight operations, the small unmanned aircraft must be equipped with anti-collision lighting that is visible for at least 3 sm.

However, the remote PIC may reduce the intensity of the light if the remote PIC determines it is in the interest of safety to do so. For example, a bright light or a bright strobe light on the small unmanned aircraft in very close proximity to the remote pilot could cause the remote pilot to lose the ability to observe the small unmanned aircraft’s location, speed, attitude, or altitude with accuracy. The remote pilot maintains the discretion to reduce the intensity of the anti-collision lighting when they determine it would be in the best interest of safety to do so. Discretion is an important component of § 107.19, which states that the remote PIC is directly responsible for the operation of the small unmanned aircraft. The remote PIC must ensure the operation of the small unmanned aircraft complies with all regulations of part 107. This includes the requirement to maintain the capability of visually observing the small unmanned aircraft. Section 107.29 does not require small unmanned aircraft operating during the day to have illuminated small unmanned aircraft anti-collision lighting. Lighting is generally not effective for mitigating risk of collision during daytime operations. Remote pilots may exercise their discretion, however, and elect to have lighting on during all daytime operations.

5.7.2.3 A remote PIC or operator may request a waiver of the anti-collision lighting requirement for operations at night and during civil twilight. The process for requesting a waiver is two-fold: the requester must (1) fully describe the proposed operation, and (2) establish the operation can be safely conducted under the terms of a Certificate of Waiver (CoW). Paragraph 5.20 below describes the application process for waivers.

5.8 O perations Over Open -Air Assemblies of Persons. Remote pilots are prohibited from operating a small unmanned aircraft as a Category 1, 2, or 4 operation in sustained flight over open-air assemblies, unless the operation meets the requirements of 14 CFR part 89, § 89.110 or § 89.115(a). Category 3 operations are not allowed over an open-air assembly of persons.

Note: See paragraphs 8.3.2 and 8.3.6.4 for more information regarding open-ai r assemblies of persons.

5.9 VLO S Aircraft Operation. The remote PIC and person manipulating the controls must be able to see the small unmanned aircraft at all times during flight (§ 107.31). The small unmanned aircraft must be operated closely enough to ensure visibility requirements are met during small UAS operations. This requirement also applies to the VO, if used, during the aircraft operation. The person maintaining VLOS may have brief moments in which they are not looking directly at or cannot see the small unmanned aircraft, but still retain the capability to see the small unmanned aircraft or quickly maneuver it back to VLOS. These moments may be necessary for the remote PIC to look at the controller to determine remaining battery life or for operational awareness. Should the remote PIC or person manipulating the controls lose VLOS of the small unmanned aircraft, they must

5-6 regain VLOS as soon as practicable. Even though the remote PIC may briefly lose sight of the small unmanned aircraft, the remote PIC always has the see-and-avoid responsibilities set out in §§ 107.31 and 107.37. The circumstances that may prevent a remote PIC from fulfilling those responsibilities will vary, depending on factors such as the type of small UAS, the operational environment, and distance between the remote PIC and the small unmanned aircraft. For this reason, no specific time interval exists in which interruption of VLOS is permissible, as it would have the effect of potentially allowing a hazardous interruption of the operation. If the remote PIC cannot regain VLOS, the remote PIC or person manipulating the controls should follow pre-determined procedures for the loss of VLOS. The capabilities of the small UAS will govern the remote PIC’s determination as to the appropriate course of action. For example, the remote PIC may need to land the small unmanned aircraft immediately, enter hover mode, or employ a return-to-home sequence. The VLOS requirement does not prohibit actions such as scanning the airspace or briefly looking down at the small unmanned aircraft CS.

5.9.1 U naided Vision. VLOS must be accomplished and maintained by unaided vision, except vision that is corrected by the use of eyeglasses (spectacles) or contact lenses. Vision aids, such as binoculars, may be used only momentarily to enhance situational awareness.

For example, the remote PIC, person manipulating the controls, or VO may use vision aids to avoid inadvertently flying over persons or conflicting with other aircraft. First person view devices may be used during operations, but do not satisfy the VLOS requirement.

5.9.2 VO. T he use of a VO is optional. The remote PIC may choose to use a VO to supplement situational awareness and VLOS. Although the remote PIC and person manipulating the controls must maintain the capability to see the small unmanned aircraft, using one or more VOs allows the remote PIC and person manipulating the controls to conduct other mission-critical duties (such as checking displays) while still ensuring situational awareness of the small unmanned aircraft. The VO must be able to communicate effectively with regard to the following:

• T he small unmanned aircraft location, attitude, altitude, and direction of flight;

• The position of other aircraft or hazards in the airspace; and

• The determination that the small unmanned aircraft does not endanger the life or property of another (§ 107.33).

5.9.2.1 To ensure the VO can carry out their duties, the remote PIC must ensure the VO is positioned in a location where the VO is able to see the small unmanned aircraft sufficiently to maintain VLOS. The remote PIC can do this by specifying the location of the VO. The FAA also requires the remote PIC and VO coordinate to (1) scan the airspace where the small unmanned aircraft is operating for any potential collision hazard, and (2) maintain awareness of the position of the small unmanned aircraft through direct visual observation (§ 107.33). The remote PIC and VO would accomplish this by the VO communicating to the remote PIC and person manipulating the controls the
