1. Mission

1.1. Objective: To successfully complete areal mining and geological surveys using an 

unmanned aircraft equipped with spectral imaging sensors or LIDAR.

1.2. Description: Persistence Mining Inc.in full cooperation with the New Mexico Institute of 

Mining and Technology and the New Mexico Bureau of Geology, will use a small unmanned 

aircraft systems to perform geological surveys. Persistence Mining will perform surveys with 

qualified manufacturer trained personnel who have current commercial pilot certificates. The 

remote locations of these inspections, primarily mining site, outside of inhabited areas and 

cities, in geologically important areas creates an ideal use for a remote unmanned aerial 

surveys such technology. By conducting these inspections in adherence with all Federal 

Aviation Regulations that are applicable to a small unmanned systems, our team hopes to 

produce a real world example of how UAV’s can increase knowledge, productivity and 

generate beneficial data to help in both geological research for education, safety, and 

commercial industries.

2. Vehicle Description: ARMDS

2.1. CIT Engineering Overview: CIT Engineering, Inc. is a California based company located in 

Carlsbad; CA. CIT is focused on providing unmanned aerial system and robots for specific 

client needs. 

2.2. CIT Engineering has built a drone for Persistence Mining Inc. as an amateur aircraft.

2.3. ARMDS Overview: 

2.4. Map remote communities in mining areas in North America, keep our highways clear and 

safe; and provide volumetric analysis for open pit mines.

2.5. The ARMDS can carry payloads up to 9 Kg (20 lbs.). The ARMDS flies with a maximum 

wind threshold of 21 NM for sustained winds and wind gusts up to 35 NM. What is unique 

about the ARMDS is that the system automatically compensates for wind versus relying on 

the operator’s ‘sense of feel’ for what the impact of the wind is at the altitude the system is 

flying. The end result is a system capable of gathering high quality aerial intelligence at 

much higher wind thresholds. 
Persistence Mining Inc. ARMDS Flight Manual

2.6. The ARMDS has an operational range of up to 21 NM (25 Miles). All flight operations are 

GPS controlled making the system extremely easy to navigate. At any point if the operator is 

not explicitly commanding the system to move, the system automatically holds its GPS 

position (i.e. GPS hold for reliable location hover). Camera positioning is also GPS controlled 

allowing for the most sophisticated camera targeting available. The flight control system 

employs not only GPS positioning but a variety of sensors including sonar, barometric 

pressure, temperature, wind speed and others to ensure the most stability of any system in 

its class-regardless of the wind.

2.7. The ARMDS can be operated in both semi and fully automatic flight modes. Creating 

preplanned gridline flight paths to fly in autonomous mode is as simple as clicking on the 

map to create a preplanned flight plan. In semi-autonomous mode, the operator clicks on the 

map and the ARMDS automatically flies to the point on the map where the operator is 

pointing. Pre-mission waypoints, Landing zone points and flight area dimensions can all be 

entered during preflight ensuring the ARMDS operates solely within specified parameters

2.8. The ARMDS includes many advanced safety features that make it safe near roadways and 

in urban and rural areas. Built-in intelligent fault handling allows the ARMDS to detect a 

system fault while in the air, and to automatically fly back to its take-off location and land. 

Faults which can be detected by internal sensors include: loss of communication RFP: 

Unmanned Aircraft Vehicle (UAV) for “at height” Inspection to the command station; 

exceeding pre-set wind thresholds exceeded; and low battery levels. In addition, the 

operator can create no fly zones or maximum flight ranges and altitudes so the system 

cannot enter areas deemed unsafe, populated or unnecessary exploration. Automated flight 

checks ensure the system is operating at peak performance prior to take off. 

2.9. The ARMDS can be operated entirely by a touch-screen and a GPS map based interface. 

Translated: the operator only needs to program the system where to go, the specific 

dimensions of the gridlines and then system automatically plots the course within the 

parameters to gather necessary research data. Maps can be saved and flight plans can be 

made or recalled with no internet connection required.

2.14.1 Pre-flight checklist includes:

2.14.1.1 Visual inspection of the airframe

2.14.1.2 Visual inspections of rotor integrity

2.14.1.3 Check charge of all batteries (aerial vehicle, command station, radio 

repeater station)

2.15 Reliability: The system is designed for maximum reliability to maintain performance over 

its life. The only components experience routine wear are rotors, batteries, motors, and 

legs. Battery and motor conditions are monitored by the system with deviations reported 

to the operator.

2.15.1 Contact with other objects during flight may cause other components, particularly 

rotors, and motor arms, to become damaged. Damaged components are likely to 

be detected during the full visual inspection of the airframe performed before 

each flight. Structural damage affecting flight characteristics will be detected by 

on-board sensors.

2.15.2 The UAV system detects numerous conditions which may make flying unsafe, 

such as reduced GPS accuracy, magnetic anomalies, low battery charge, battery 

cell imbalances, and temperature fluctuations. Automatic pre-flight checks 

prevent the UAV from taking off if such conditions are present; or, if the condition 

is detected during flight, the system will trigger a Fatal Conditioned Response.

2.16. Fault Tolerance: The key feature of the UAV fault tolerance is its mechanical simplicity. It 

uses. Any component failure detectable by the system will be reported to the control 

station and will cause the UAV to perform a Fatal Condition Response (FCR) or NonFatal Conditioned Response (NFCR), depending on the type of failure.

3. Command and Control Systems

3.1. The ARMDS Ground Controls allow the operator to control the aircraft and its payload 

sensors. The touch screen control allows for quick navigation and data entry while the 
Persistence Mining Inc. ARMDS Flight Manual

7

display screen provides all essential flight data to the operator. Telemetry data is

transmitted to the command station at a minimum rate of once per second.

3.2. Displayed on GCS:

3.2.1. UAV Position

3.2.2. Navigation Route

3.2.3. UAV Tail Number

3.2.4. UAV Position

3.2.5. UAV Altitude

3.2.6. UAV Heading

3.2.7. North Seeking Arrow

3.2.8. Range to Target

3.2.9. Calculated target position

3.2.10. Date/time

3.2.11. Sensor heading and orientation relative to UAV

3.3. On-board Flight Instruments

3.3.1. The UAV is equipped with an Inertial Navigation System (3-axis gyroscope, 3-

axis magnetometer, GPS receiver, and static pressure sensor) and a sonar 

sensor for precision AGL altitude measurement.

3.4. On–board computer systems 

3.4.1. The UAV is equipped on-board computer systems to monitor (sensors, battery, 

etc.), control (speeds, altitude, position, etc.), and communicate (control, 

telemetry, etc.).

3.5. On-board guidance and navigation equipment

3.5.1. The UAV can operate autonomously; it does not require any input from groundbased equipment after it‘s preflight programming.

3.6. Frequency Allocations- 915 MHz, 2.4 GHz, 5.8 GHz

3.7. Flight termination link
Persistence Mining Inc. ARMDS Flight Manual

8

3.7.1. To prevent a “fly away” or other potentially dangerous situation a flight 

termination link is available to the operator from the ground control system.

3.8. Takeoff and Landing – The ARMDS has vertical lift autonomous launch and recovery. A 

Landing Zone “LZ” is designated by the operators and identified in the GCS software. For 

launch procedures the aircraft will takeoff and hover 3 meters directly above the LZ and hold 

until further operator instruction is given. The aircraft will automatically adjust for wind during 

this period.

3.9. Navigation System 

3.9.1. Specific maps can be downloaded to the display screen (such as air sectional 

and geographic maps) which is overlaid with GPS positional data. Waypoints can 

be created before and during flight operation creating specific locations and 

sequences for the aircraft

3.10. Redundant Systems 

3.10.1. The UAV combines the input from a multitude of sensors. Even though the data 

from all sensors is required for optimal system performance, a single sensor 

malfunction is likely to result in degraded performance rather than leading to a 

catastrophic failure.

4. Emergency Procedures and System Failures

4.1. Failure Handling – The UAV has extensive failure detection and handling capabilities. All 

failures are deeded to be either fatal or non-fatal. Failures classified as fatal result in a 

Fatal Condition Response (FCR); and failures classified as non-fatal result in a Non-Fatal 

Condition Response (NFCR).

4.2. Sensor Failure – Failure of on-board flight instruments/sensors will degrade the UAS 

performance and will result in either a FCR or a NFCR, depending on their severity. If the 

UAV becomes unstable due to sensor failure, it will stop all four motors and free fall to 

avoid a fly away condition.
Persistence Mining Inc. ARMDS Flight Manual

9

4.3. Motor Failure – The UAV flight performance will degrade significantly if one or more 

motors fail.

4.4. Airframe Failure – If airframe is damaged in ways that impacts flight characteristics, the 

UAV will behave similar to if an on-board flight instrument failed.

4.5. Navigation System Failure – In a navigation system failure, degraded GPS will result in 

FCR or NFCR‘s depending on failures.

4.6. Power Failure – A complete battery failure which results in power loss to the UAV will 

result in degraded flight performance.

4.7. Low Battery Condition – Operator will be alerted of a low battery condition and will land 

the aircraft as soon as able.

4.8 Low Battery Condition – Operator will be alerted of a low battery condition and will land 

the aircraft as soon as able.

4.9. Line-of-Sight Loss – All flight operations will be conducted with the UAV within visual 

sight of a spotter. If the spotters view becomes obstructed and line-of-sight is lost, the 

pilot may instruct the UAV to hover in place until line-of-sight is reestablished, to return to 

the take-off position, or to land at the current position.

5. Security

5.1. The system and communication links are encrypted by the manufacturer’s proprietary 

software.

6. Operations

6.1. Crew Requirements – Persistence Mining Inc. has named two operators to this inspection 

program. Both are commercially rated pilots and have years of experience in multiple 

unmanned systems. Operators will be flight current for both manned and unmanned 

standards and as well hold a current Class II FAA Medical Certificate along with 

appropriate flight currency.

6.2. Operator roles:

6.2.1 Operator/Pilot in Command (PIC) – For each operation a PIC will be designated, 

this person will be directly responsible for the operation of the UAS and the 
Persistence Mining Inc. ARMDS Flight Manual

10

safety of the operation. It will be the responsibility of the PIC to ensure the 

operation complies with applicable regulations and/or ensures professional “best 

practice” to all applicable regulations.

6.2.2 Spotter/back-up Pilot – The Spotter will be responsible to visually maintain 

contact with the UAV while scanning the area for undetected aircraft or 

obstacles. The Observer will also handle the communications between the PIC, 

external crew, air safety officer and the platform safety officer. The observer will 

also be a certified and a current system operator and will assume control of the 

UAS should the PIC become incapacitated.

6.2.3 Operator profiles:

6.2.3.1 Maintenance: Operators will hold appropriate maintenance certification 

for the system provided by the UAV servicer and/or manufacturer.

7. Safety

7.1. Safety is priority for every mission. The location and details of the task demand the safe

operations. Several layers of safety management will be implemented for this operation:

7.2. All flight operations must meet standards written in the Pre-mission operations plans and 

risk matrixes will be reviewed prior to any operation. During operations, Safety Officer(s)

will be present along with Persistence Mining personnel who all have “stop work 

authority” over the operation.

7.3. FAR & ICAO Regulations. This operation will conduct under all applicable FAA and ICAO 

regulations. While the location and scope of this operation provides exemption from many 

of the regulations, Persistence Mining Inc. Persistence will ensure operations fall under 

“best practice” of all appropriate regulations.

7.4. Persistence Mining Standard Operating Procedures.

7.4.1 Persistence Mining Operators will maintain internal company safety practices at 

all times. These internal regulations are in addition to all applicable FAR, ICAO 

standards.
Persistence Mining Inc. ARMDS Flight Manual

11

7.5. Stop Work Authority. Any Persistence Mining personnel can, at any time, halt an 

operation in the name of safety without retribution or concern for their jobs.

7.6. Operating Standards – To assure safe operation within close proximity to roads or 

possibly inhabited areas the ARMDS will be operated in autonomous mode at all times. 

Manual operation is only permitted in the case of an emergency procedure as stated in 

the aircraft operational procedures manual.

7.6.1 Safe Operating Standards

7.6.1.1 Efforts will be in place to ensure that an emergency free fall to the ground 

will not result to damage or injury to persons or property.

7.6.1.2 The PIC shall be designated for every flight and operations members 

must comply with PIC instructions or any person whom the PIC has 

authorized to act on behalf of the PIC.

7.6.1.3 Operations will not occur beyond visual line-of-sight (VLOS) and will be 

within the inspection region of the platform.

7.6.1.4 The UAV will follow the same right-of-way rules as any manned glider, 

airplane or helicopter. Since the UAV will be operating within VLOS they 

shall give way to manned aircraft at all times.

7.6.1.5 The operation will take place only under visual flight conditions and all 

applicable visual flight rules will be followed.

7.7 Site Survey – An on location site survey will be conducted by assigned operators prior to 

any operation. Site surveys will be coordinated with all interested parties prior to flight 

inspection. 

7.7.1 Locations of hazards

7.7.2 Location of Launch/Recovery site

7.7.3 Location of forward observers

8. Mission Parameters

8.1. Dimensions – Persistence Mining operators will act inside the surveyed flight Inspection 

area. These parameters will be programmed prior to any survey and in accordance with 
Persistence Mining Inc. ARMDS Flight Manual

12

specific needs of the survey area and needs of the client. This will create a digital flight 

box for the UAS and a grid system where we can identify the location of the UAS at all 

times.

8.2 Example

8.3 Operating Altitude – The UAS will operate at or below 400 ft. AGL at all times.

8.4 Lateral Distance – The UAS will stay within 2 miles laterally of the pilot at all times.

8.5 Air Traffic De-confliction – There is a very small volume of air traffic in the survey regions

due to the remote locations. All air traffic in the area is almost completely limited to 

helicopter traffic coming to and from the production platform. These helicopter flights are 

scheduled and in constant communication with platform air traffic officer. Inspections will 

occur in “dead” periods in- between scheduled arrivals and departures. Operators will 

have aviation band radios with communications to the air officer at all times.

8.6 Emergency return-to-base – The system will be pre-programmed with an emergency

return-to home waypoint. Should notice be given by an observer or air traffic officer the 

system will at all times be able to return to land within a five minute period.

8.7 Observers – The back-up PIC will act as the observer and be in communication with the 

safety personnel and flight officer /pilot, as well as aviation frequencies for the platform.

8.8 Communication – The operating personnel will have direct communication links to the 

observers, safety personnel and monitoring geologists. The safety personnel will handle 

the communications for the flight operations team. The flight officer/pilot will have an 

aviation band radio to communicate with any traffic in the area.

9. Pre-Flight

9.1 Flight Operations Area – Prior to starting operations, the flight team will set up equipment 

in a fight controls in a stationary area with a distance from the take-off pad of a minimum 

of 20 meters insuring safety.

10.1.3 Approval from Observer

10.1.4 After the PIC has received clearance from these sources the PIC will have 

authority to proceed with the operation.

11. Recovery

11.1 Recovery operation will take place at pre-determined LZ. The LZ will be clearly marked as 

such to ensure safety with ground personnel.

11.2 Authority to Recover – The system cannot be recovered until it is safe to do so as 

determined by the Persistence Mining personnel on duty.

11.3 Communication – After recovery operation is complete operators will inform air traffic 

officer and safety officers that the vehicle is safe on deck. Any notification to the airspace 

control/change of status to any flight plans will be report at this time.

91.7(a). Civil aircraft airworthiness Certificate Persistence seeks the requested relief 

because the ARMDS does not require an 

airworthiness certificate in accordance with 

14 C.F.R. Part 21, Subpart H. Therefore, we 

will ensure that the ARMDS is in an 

airworthy condition based upon its 

compliance with the operating documents 

prior to every flight, and as stated in the 

conditions and limitations of our operations 

manual.

Persistence Mining is a small mining company with headquarters in La Jolla CA. Our personnel have 

experience operating unmanned systems to provide geological and agricultural surveying data to clients. 

With our alliance to educators and researchers, the Persistence Mining team will be able to assist 

researching in mapping and discovering various geographical features that will assist in a number of 

research areas.

ARMDS is currently working with a large petroleum company to develop the procedures and safety plans 

to support remote sensing operations on production platforms in the Gulf of Mexico. The purpose of this 

program is to support enhancing incident response times and improve safety of platform inspections for 

numerous objectives including, but not limited to:

1. Geo-mapping for explorations

2. Emergency Response Protocols for natural disasters

3. Fluvial Studies

4. Hyper spectral imaging maps

The first phase of the development project will be to decrease the amount of pitch and tilt during flight 

and turns within a grid pattern

2014-15 year. These inspections will occur in after each flight to guarantee advancements in proceeding 

flights

Approximate Location of the areas to be surveyed:

1. Remote areas near Hawthorn, Nevada

2. Remote Areas in Playas New Mexico

3. Other remote mining areas 

4. Agricultural areas

All operations will be conducted in specified areas with a pre-determined flight plan by personnel who 

hold current commercial pilot certificates. These PICs will be trained to the highest level and certified to 

operate by the unmanned system manufacturer.

Through this program Persistence Mining will establish an aerial surveying program for geo-mapping, 

environmental services support as well as to develop safety procedures and best practices for such 

operations.

We are requesting exemptions from the Federal Aviation Regulations so this operation can be 

commercially completed in accordance to all applicable FARs that would pertain to a small unmanned 

system. It is our team's hope that through exemption from inapplicable regulations Persistence Mining 

Inc. Will be able to provide the United States government and the FAA a source of performance data 

from the safe and successful conduct of commercial UAS operations. The remote locations of this request 

provides a unique opportunity to further the process of UAS integration into the NAS with strict safety and 

access controls already in place for the locations of the inspections.
