# Part 1

– Visual Observance Seminar

# Perception

 

### Perception  The ability to see, hear, or become aware of something through the senses.  Detection of a Sensory Stimulus  Typical UAS Sensory Stimuli  Visual Stimuli  Light Flash  Color Change  Sound Stimuli  Humming  Grinding  Odor Stimuli  Melting Plastic

# Concepts

 

### Central vs. Peripheral Vision  Central vision is where your acuity and color vision is best  Acuity

– Sharpness in Visual Perception  Utilized for high resolution and focus.  

### Peripheral Vision  Orientation  Relative Speed/Movement  Motion in your surroundings

# Acuity

– Visual Sharpness

 

### Our resolution is a function of pixels  Important for Visual Line of Sight Rules  UAS must be flown within UNAIDED VISUAL LINE OF SIGHT  Aid is permitted via contact lenses/prescription lenses but nothing else  Visual Sharpness or Acuity is Necessary to Pick Out an aircraft over long distances  Particularly important with UAS because of the small size of the aircraft

# Contrast Issues

# Depth Perception

 

### Depth Perception  Difficult beyond 20 yards  Limited to 200 yards  

### Points of Reference are needed  Visual overlay  Haze  Shadow

# Depth Perception Continued

 

### Size Reference

# Depth Perception Question

 

### How far away is this Boeing 787 Dreamliner?  

### Difficult with no reference point.

# Visual Observance Challenges

 

### Altered appearances compared to ground operations  

### Atmospheric effects (dust and humidity)  

### Cloud Color vs. Craft Color  Loss of Contrast  

### Haze is a distant visual cue  

### Light sources from below  

### Light angles can hide shadow cues  

### Loss of Depth, Texture, and Size cues  

### Indistinct features are difficult to assess

# Example

– Loss of Contrast

# Relative Motion

 

### Relative Motion  Objects moving in our peripheral vision are easier to detect  Remember Peripheral Vision is used for motion  

### Objects moving toward or away from you are difficult to perceive  Central Vision is for sharpness and HD Vision, not motion  https://www.youtube.com/watch?v=2vMbATfG

# Strategies for Better Visual Observance

 

### Beware of conditions that degrade image sharpness  

### Correct scanning techniques  

### Improve contrast issues  

### Aircraft color/lighting, vantage point, light conditions  Alter aircraft coloring if necessary  

### Check backgrounds for contrast  

### Colored lenses (in some settings)

# Things to Consider

 

### Beware of visual obstructions  Color and shape similarity  

### Consider relative motion problems  Central vs. Peripheral Vision

# Classroom Training – UAS Flights

# Why do we need a Visual Observer?

 

### Why?  Compliance with applicable sections of Title 14 of the Code of Federal Regulations (14 CFR) to operate in the NAS  Compliance with the Petition for Exemption and Granted Section 333 Exemption  To ensure at least an equivalent level of safety as is provided by existing rules and regulations for the National Airspace System as developed by the Federal Aviation Administration

# Observer Requirement

 

### Observer Requirement  

### VOs must;  Not allow the aircraft to operate beyond the visual line
-of
-sight  Be able to see the aircraft and the surrounding airspace sufficiently at all times  Determining the UA’s proximity to all aviation activities and other hazards (e.g., terrain, weather, structures )  Exercising effective control of the UA  Complying with 14 C.F.R. 91.111, 91.113, and 91.115  Preventing the UA from creating a collision hazard  I nform the PIC before losing sufficient visual contact with the UA

# Observer Requirement

 

### Observer Requirement  

### Why are visual aids not permitted to be used to keep an aircraft within “Line 

### of Sight?”  Visual Aids including;  Telescopes  FPV Goggles  Binoculars  Distort vision and alter an observer’s field of view

# Observer Requirement

 

### Observer Requirement  

### In a UAS flight crew the PIC operates like a captain and the VO as the 

### assistant, therefore the PIC will select a location from which the VO will perform their duties so as to afford the best available view of the entire area 

### within which the operation is to be conducted .

# Communications

 

### Communication Requirements  

### A VO provides see- and
- avoid assistance to the PIC and due to this, must have 

### immediate communication with the UAS pilot  Verbal Communication Range at all times  Not Permitted  Cell Phones  Text  Walky
- talkies

# Post- Observer Training Qualifications

 

### UAS Observer Qualifications  

### All observers must have an understanding of Federal aviation regulations 

### applicable to the airspace where the UAS will operate.  Observers are considered crewmembers  Observers must NOT perform crew duties for more than one UAS at a time  Observers are not allowed to be both the VO and PIC

# Observer Qualifications

– Regulatory Knowledge

 

### UAS Observer Qualifications  

### Observers must complete sufficient training to communicate to the pilot any 

### information required to remain clear of conflicting traffic, terrain, and obstructions, maintain proper cloud clearances, and provide navigational awareness .  Overview 14 CFR:  91.111 , Operating Near Other Aircraft;  91.113 , Right
-of
-Way Rules: Except Water Operations;  91.115 , Right

 

### Proposed operations using sUAS in the United States under the granted form of this Petition for Exemption will be limited to;  Aircraft contained in the approved Exemption Petition  Aircraft weighing less than 55 pounds including batteries and operational & technical payloads  Aircraft not exceed 100mph speeds 

### Commercial UAS Flights will be limited to those stated within an approved

petition for exemption  

### All of these flights will take place in Class G airspace nationwide unless otherwise advised in a FAA
- Granted Certificate of Waiver or Authorization  

### Adherence to 200 Foot Automatic COA unless granted a further COA  After receiving an exemption number from the FAA 

# Section 333 Petition for Exemption Parameters 

### All flights conducted will be below 400 feet AGL (Above Ground Level)

 

### All flights will be carried out by a trained flight crew consisting of a licensed 

### (at minimum Sport Pilot’s Certificate) PIC with a Medical Certificate or equivalent valid U.S.A. Driver’s license and a trained Visual Observer.
 

### All flights conducted will include aircraft that are flying below the 87 knot 

### (100 mph) airspeed maximum, highlighted by the FAA in their guidelines. 

# Section 333 Petition for Exemption Parameters 

### All flights conducted will be conducted within Visual Line of Sight and adhere to

Visual Flight Rules under the Visual Meteorological Conditions associated with Class 

### G airspace.  Link to VMCs

National_Airspace_System_Overview.pdf  

### The Petitioner will not allow any PIC to operate a sUAS unless the PIC meets the 

### qualification standards set by the Federal Aviation Administration (i.e. Minimum
- Sport Pilot’s Certificate/Medical or U.S.A. Driver’s License) and by the safety 

### guidelines and operational capabilities relating to safe sUAS operations, such as ;  Evasive Maneuvers  Emergency Actions  Fail
-Safe Knowledge  Flight Skills  Maintaining adequate distances from;

 People  Property  Structures  Etc. 

# Section 333 Petition for Exemption Parameters 

### PIC qualification flight hours will be logged in a manner consistent with 14 C.F.R.



### 61.51(b). Additionally, a record of the PIC training will be documented and made available upon request to the Administrator.
 

### Training operations will only be conducted during dedicated training sessions. During training, all persons not essential for flight operations will be deemed nonparticipants, and thus, the PIC will operate the UA with appropriate distance from nonparticipants in accordance with 14 C.F.R. 91.119.
 

### As highlighted by the FAA, the Visual Observer’s duty is to visually observe the 

### relevant airspace for aircraft, hazards, obstacles, structures, or the like. For this reason, the VO will not be allowed to operate the camera or other instruments.  A third operator must be utilized if the commercial flight requires a dedicated camera person 

# Section 333 Petition for Exemption Parameters 

### The PIC for the duration of an unmanned flight will be named prior to the



### flight. Due to this, once the PIC is named and a flight is begun, the PIC will not be able to transfer his/her designation as the PIC though the duration of 

### the flight. Furthermore, the PIC is the Captain of the flight crew and will ensure that the Visual Observer is qualified to hold the VO position for the duration of the flight.
 

### Each commercial sUAS flight performed will be planned for ahead of the flight date. This will be to ensure adequate time for all participants to prepare and 

### to obtain all the necessary permissions (landowners, homeowners, property owners, etc.) if any are needed. All flights will be preceded by a meeting at 

### least one day before the flight at which all participants of the flight will be present. This is to ensure adequate knowledge and preparedness prior to the 

### sUAS flight. 

# Section 333 Petition for Exemption Parameters 

### Aircraft maintenance is obviously vital for any commercial SUAS operation. It

ensures safety and is necessary prior to each flight to maintain safe, efficient, 

### and effective flight operations. Once again, the PIC, as the captain of the flight crew, will take a leading role in inspecting the aircraft prior to flight. 

### The PIC will likely have the most experience of anyone on the flight crew and will be in turned with the specific maintenance needs of each specific flight craft. If the PIC were to find an error in the flight craft or any of the 

### associated systems, including the Ground Control System for example, he/she would ground the flight until adequate maintenance is completed and the 

### aircraft is once again safe to fly. All maintenance on flight crafts will be noted and logged as to ensure the safety of all aircraft and the people operating them. 

# Section 333 Petition for Exemption Parameters 

### Relating to the above Condition, anytime a flight
-critical component is



### replaced or anytime there is mission
-critical maintenance on the craft, the PIC will conduct a flight test of the system before completing the intended, 

### commercial mission. Once again this flight test will be logged by the PIC.
 

### Routine maintenance and inspections of the sUAS will be logged by the PIC in accordance with the requirements and suggestions laid out by the aircraft 

### manufacturer in terms of aircraft component maintenance, overhaul, replacement, inspection, and life limits, which are part of the supporting 

### documents for each aircraft contained in the Exemption and Operations Manual. The logging of these maintenance/inspection checks will be included 

### in the aircraft records and include the total time of service and description of work. 

# Section 333 Petition for Exemption Parameters 

### All SUAS flights will be conducted within Visual Line of Sight (“VLOS”) of both the



### PIC and VO at all times. Furthermore, VLOS means visual observance unaided by any device other than corrective lenses such as eye glasses or contacts. The use 

### of telescopes, FPV systems (for purposes of VLOS flights), binoculars, and the like will not be permitted. Also, both the PIC and VO should be in constant, verbal communication range. The use of other devices to communicate out of verbal 

### range are not permitted. These devices would include, cell phones, text messaging, walky
- talkies, and the like.
 

### No commercial flight missions will be executed unless it can be determined that the flight crew can complete their mission from take
-off through landing, with a 

### reserve of 20% battery life. New flight crafts have adaptive battery monitors and for this reason this condition will an automated process as the Petitioner can set 

### the default Advisory and Critical Battery warnings to 30% and 20% respectively, which will warn the PIC of the depleted battery and engage him/her to fly home 

### and land with 20% remaining power. For all systems without this automated feature, a watch will be used to monitor flight times to ensure a safe return home with adequate battery power. 

# Section 333 Petition for Exemption Parameters 

### In the case of an unexpected obstacle or in
-flight issue, each s UAS operator will



### have the ability to abort a mission and take corrective actions.
 

### The sUAS utilized will be programmed so that if the sUAS loses signal with the PIC 

### or Ground Control Station during flight, the system will return to a preprogrammed GPS location located within the operating area containing the 

### flight crew. Furthermore, this failsafe can also be used in controlled situations, meaning the failsafe will be able to be engaged should something happen on the 

### ground that disallows the PIC from bringing the sUAS back in a normal fashion. Additionally, in both situations described above, where the failsafe is either a controlled action from the pilot or an uncontrolled situation, like radio
- link signal loss, the unit will not only fly back to its preprogrammed home point, it also has the ability to land itself. This creates safe operations of the aircraft even in bad situations, like signal loss, and prevents the unit from flying off uncontrollably or landing in an unknown location. 

# Section 333 Petition for Exemption Parameters 

### The operating documents required under 14 C.F.R. 91.9 and 91.203 will be

maintained and available to the PIC at the Ground Control Station of the UA 

### anytime the sUAS is operating. Furthermore, these documents will be available for review by the Administrator or other law enforcement officials 

### upon request.  

### It is always important to specify precedent when determining operating practices. For this reason, if a discrepancy exists between the conditions laid 

### out in the Petition for Exemption and the actual Granted Exemption, the conditions laid out in the finalized Granted Exemption will take precedent over the conditions laid out in the Petition. 

# Section 333 Petition for Exemption Parameters 

### As has been noted, the Petitioner will obtain written and/or oral permission

from the landowners, farmers, property owners, or otherwise authorized 

### agents for flights above their property.
 

### The Petitioner will also obtain all required permissions and permits from 

### territorial, state, county or city jurisdictions, including ;  Law Enforcement  Fire Departments  Municipal Agencies or;  Other Appropriate Governmental Bodies 

# Section 333 Petition for Exemption Parameters 

### The Petitioner will not conduct operations at night, as defined in 14 C.F.R.

1.1. Furthermore, all operations will be conducted under visual 

### meteorological conditions (VMC).
 

### All SUAS flights conducted by the Petitioner will be done so in accordance 

### with airspace requirements established by the FAA and/or an ATO
-issued COA, including;  Class of Airspace  Altitude Level, and potential;  Transponder Requirements 

# Section 333 Petition for Exemption Parameters 

### The sUAS will not be operated within 5 nautical miles of an airport reference

point as noted on a current FAA
- published aeronautical chart unless a letter 

### of agreement with that airport’s Air Traffic Control is obtained.  

### The PIC will follow VMC guidelines for VFR flights;  Visibility equal to or in excess of 3 statute miles from the PIC  Adequate distance of no less than 500 feet below, or less than 2,000 feet horizontally from a cloud  

### All operations by the Petitioner will be conducted in Class G airspace nationwide or as otherwise advised in a COA. 

# Section 333 Petition for Exemption Parameters 

### All aircraft utilized by the Petitioner operate via radio frequency, which is



### governed by the Federal Communications Commission (“FCC”). For this reason, prior to commercial operations under a granted Section 333 Exemption, the 

### Petitioner will ensure the radio frequency spectrum used to operate and control its sUAS complies with FCC rules.
 

### The PIC will always yield the right of way to all manned aircraft and aviation operations.
 

### No sUAS operations will take place while a PIC is in a moving device or vehicle .  Cars/Trucks/SUVs  Boats  Tractors  ATVs 

# Section 333 Petition for Exemption Parameters 

### All sUAS operations by the Petitioner will be conducted at least 500 feet from



### all nonparticipating people, vessels, vehicles, and structures, unless the following conditions apply;

 Protective barriers are present that adequately protect nonparticipants from flying shrapnel or debris should there be an accident .  The Petitioner has been granted permission to operate near a vessel, vehicle, or structure by the owner/controller of these properties  Operations nearer to the PIC, VO, operator trainees or essential persons do not present an undue hazard to those persons per 14 C.F.R. 91.119(a). 

# Section 333 Petition for Exemption Parameters 

### The Petitioner will log and report to the UAS Integration Office (AFS
- 80)

within 24 hours of any incident, accident, or flight operation that occurred 

### outside the horizontal and vertical boundaries of the operational area as defined by the COA under which the flight was operating . Furthermore, the 

### Petitioner will report accidents to the National Transportation Safety Board (NTSB).
