## Purpose

This Hawkeye Aircraft Mk

- III Aircraft Flight Manual (hereinafter referred to a s AFM) is provided for usage
by the PrecisionHawk authorized flight team.

This document outlines specific Safety Guidelines, Limitations, Checklists, Normal Procedures, Non

Normal Procedures, and Flight Profile information as de tailed by both the Manufactu rer and operational
best practices determined by the Aircraft Owner.

For specific equipment installations and schematics, firmware updates/requirements, Aircraft assembly,
software installations, and connecting external components

, the manufacturer provide d materials

should be consulted.

This document has been fully coordinated with PrecisionHawk’s Flight Operations Manual to assure
consistency and provide necessary cross

- checks wh ich further enhance the safety margin of each

operation.

### Page | 9 

## Introduction

The Aircraft HawkEye Mark III Unmanned Aerial Vehicle (hereinafter referred to as Aircraft) is a
lightweight UAS, weighing in at approximately 5.5 lbs. with payload. The body construction is aircraft
Styrofoam , fiberglass and composite material. It emplo ys a single 3900 mAh LiPo batter y pack and has a
typical flight time of forty

- five (45) minutes (depending on the payload) . It is outfitted with a 3DRobotic
APM autopilot. The APM autopilot is a fully integrated autopilot module that stabilizes the aircraf t in
flight using an on

- board Inertial Measurement Unit (IMU). The Aircraft autopilot module receives
waypoint commands , which then sends commands to the motor and control surfaces to achieve the
desired flight path. While the 3DRobotics autopilot is an o pen

- source product (meaning that the user
community is free to modify the hardware and software), PrecisionHawk has extensively tested one
version of hardware and one version of firmware that is used on every Aircraft. When PrecisionHawk

receives APM modu les from 3DRobotics, PrecisionHawk rolls back the firmware and hardware (if
required) to the approved version for production release, to ensure quality and consistency from one

Aircraft to the next. The Aircraft is hand

- launched, and can be landed automat ically or manually. The
landing style is traditional, but belly

- lands as opposed to having landing gear.

The Aircraft has multiple payload configurations: A 14 MPixel RGB came ra, four multispectral imagers: (i)
Tetracam ADC Lite / Mini

- MCA and a high

- reso lution imager, (ii) a high

- and low

- resolution
microbolometer, (iii) a line

- scanning LIDAR, and (iv) a push broom or snap shot hyperspectral sensor.
Through these configuration s , and through the Aircraft’s design, an operator can collect high

- resolution,

r emote sensing data with minimal effort.

Operationally, the Aircraft automatically computes flight paths, survey parameters, take

- off and landing
paths, as well as other vital information. Once a survey is complete, software will pull information from

the aircraft computers and automatically connect to Wi

- Fi or other networks and transfer all remote
sensing data, flight information and diagnostics to remote servers. Users are never required to manually
generate plot mission paths or build flight plans based off of weather conditions. Instead, the aircraft
will automatically adapt to its current conditions.

The artificial intelligence that operates all elements of the UAV and makes aerial and data decisions
throughout the PrecisionHawk system is the core rea son why PrecisionHawk has been able to secure
sub 1 cm per pixel imagery, a market

- leading aerial resolution. In addition, the aircraft is equipped with
advanced diagnostic capabilities, enabling it to monitor all facets of the mission from power

consumpt ion to airframe fatigue to survey quality.

The Aircraft connects to the Pilot through the PrecisionHawk Flight Planner and ArduPlane Mission

Planner Ground Control Station Software via long range dedicated radio link . Additionally, the Futaba

compatibl e RC transmitter interface allows direct interaction

.

## Notice to Operators

It is the responsibility of the owner/operator and PIC to operate the aircraft in a safe manner consistent
with their Flight Operations Manual and this Aircraft Flight Manual. Adh ering to these guidelines helps
significantly reduce the risk of injury to persons or damage to property.

Each owner authorizing, and PIC using, the Aircraft is responsible for compliance with all regulations
governing the use of the Aircraft.

Preci sionHawk does not accept any responsibility for the damages or financial compensations which
may arise as the result of an owner operating or auth orizing a pilot to operate and failing to comply with
any of the respective regulations , leading to a claim of a third party against the user.

## Supplementary Procedures

Aircraft Control Method

The Aircraft can be controlled through autonomous or manual control.

Fully autonomous control of the aircraft, the nominal mode of operations, utilizes the Mission Control Computer (MCC) to undertake the flight path generation functions, payload control, and determining optimal landing and recovery paths. This also includes diagnostics and threshold monitoring during operations and preprogrammed flight specified by waypoints and commands from users through 3D Robotics’ Mission Planner ground control

station software. The vehicle is able to autonomously maintain stability th rough the onboard 3D Robotics’ Auto Pilot Module ( APM ) 2.6 Autopilot which stabilizes the aircraft.

Flight planning is through the MCC. The MCC then changes the modes of the aircraft as well as waypoints defining the flight path.

Another level of contr ol utilizes the autopilot capabilities, with the Aircraft receiving commands and desired actions from a hand coded controller with autonomous capability through the addition of an onboard Mission Control Computer (MCC) instead of the existing Mission Plann er control software. A Futaba

- compatible RC transmitter is used to provide remote control capabilities and manual override for the vehicle. In this case, the pilot has direct control of the aircraft ’ s flight control surfaces.

Additionally, the PIC can control the aircraft via the Futaba 2.4 MHz Controller. During this mode of operation , the PIC can use the ground software and modify flight parameters.

## Non

- Normal Procedures.

General Guidelines and Situations W ithout Checklists:

It is important that all PrecisionHawk Flight Team Members become familiar with the situations listed below, as

well as the Non

- Normal Checklists associated with them

. The behavior of the system when encountering an
abnormal event or operating condition outsi de of the expected performan ce envelopes will fall under this section.
However, specific failures and responses will generally be handled in the following manner for each failure type.



### Aborted or Failed Launch and Recovery

If an aborted takeoff is neces sary, the throttle of the vehicle is to be reduced, and the desired target
altitude of the vehicle should be set to zero in order for it to touchdown. Alternatively, landing can also be aborted by applying throttle and setting a desired altitude for the ve hicle to regain. These steps can be initiated either through the manual control of the aircraft by the pilot or through the control station by the control station operator

.

In addition, in the event of a failed recovery, the pilot can take control of the aircraft to manually land or to allow the autonomous system to attempt another landing.



### Airframe Damage

In the event of loss of control due to airframe damage, the aircraf t will attempt to maintain mission operations. In the event that the damage is sufficient to preclude proceeding with the mission, but the system still has some control, it will attempt to return to the recovery area. Should this not be possible,

all cont rol surfaces will go to predefined positions, and the system will try to ground the vehicle at the current location and terminate servo outputs after a certain amount of time.



### Autonomous Emergency Recovery Scheme

Should an emergency recovery be required during autonomous operations, there are several recovery options that can be instigated:

1. The aircraft is commanded to autonomously return to the recovery area and land

2. The aircraft is commanded to autonomously return to the recovery area whereby the pilot will

assume control and land the aircraft

3. The pilot manually assumes control of the aircraft and returns it to the recovery area and lands the

aircraft.

The specific recovery option exercised will be at the discretion of the PIC.



### Battery or Electron ic Systems Failures

In the case of low battery, the aircraft will be flown home or rally when the aircraft battery reaches a certain capacity threshold. This is typically a capacity such that the aircraft will have sufficient capacity to

return home to th e designated landing area given flight and weather conditions. This will be initiated automatically by the Mission Control Computer (MCC). In addition, in the unlikely event the MCC is unable to provide this function; the Flight Control Computer (FCC) has its own, preconfigured fail

- safes. This also returns the aircraft to the home position.

If the battery level reaches critical levels, the propulsion motor off will be shut off, and the aircraft will be landed at the current location. This prevents the lo ss of an aircraft due to autopilot reboot caused by low voltage. It also ensures that the control of the flight control surfaces is maintained.

### Page | 28 

### Communications Failures

There are configurable failsafe conditions in the Mission Planner APM 2.6 autopilot s oftware. In the case
of communication loss, the aircraft can be configured to fly home or land after certain time has passed

without re

- establishing communication. Similar actions will be taken for conditions such as loss of the
vehicle uplink, loss of “li ne of sight”, and radio interference. There will be real time visual and/or auditory
warning signals that will report the signal loss to the operator. Note: There have been mandatory fail

safes hard

- coded in the PrecisionHawk HawkEye Aircraft platform.



### Cr itical Systems Abort Procedure

In the event of a critical systems abort, all control surfaces will go to predefined positions, and it will try to ground the vehicle at the current location and terminate servo outputs after a certain amount of time.



### Emer gency Flight Termination System

In the event of a critical system failure, the user may send a command over the radio control link to terminate the flight. This link (through the Futaba hand controller) is a separate and independent radio

link from the r adio link used by the autopilot for command and telemetry. When the flight termination system is activated, all control surfaces will go to predefined positions, and the throttle is set to zero to try to ground the vehicle at the current location. In the case of loss of radio frequency link, the same failsafe

actions for loss of communication will be taken.



### Emergency Landing Safety

Flight operations will not be held over buildings or persons. Thus, there should not be a risk to persons or buildings in t he event of an emergency landing. The aircraft is also very small with little kinetic energy and should pose virtually no risk of damaging crops or other properties in the event of an emergency landing where the aircraft is not able to return to the design ated recovery area.



### Engine Failure

In the event of flight termination due to an engine system failure, the aircraft will attempt to immediately

return to the launch and retrieval area. If the aircraft does not have sufficient altitude to return to the recovery area it will attempt a safe la nding once the altitude has dropped below a set threshold (typically

30 m above ground level).



### Manual Override Capabilities

When flight is autonomous, manual override for one of the vehicles can be initiated by selecting “manual”

mode in the Mission Pla nner software. Alternatively, one of the channel switches on the RC transmitter, dedicated to this purpose, can easily be switched to the “On” position, immediately transferring direct control of the aircraft to the pilot. Thus, it is fast and simple to re gain manual control of the vehicle.



### Minimizing Critical Component Failure

The primary failure prevention system on

- board the aircraft is the use of independent computers operating on board the aircraft simultaneously. Each of t hese computers (one of whi ch will be contained within the autopilot system and one for mission level contro l ) will be able to provide information on the

health of the other.

### Page | 29 The system is designed such that fail

- safe situations (loss of communications, low battery, and loss of GPS, etc.) can be predefined such that safe maneuvers can be executed by the vehicles in case of emergency to minimize risk to the vehicle systems, support crew

, or other persons or property.



### Navigation System Failure

In the case of a navigation system failure (for example, GPS lock is lost), the aircraft will be put in a shallow bank. By putting the aircraft in a shallow bank

, the distance the aircraft can wander is limited

, and the GPS is given the opportunity to re

- acquire lock. If GPS lock is not rea cquired

, the autopilot is programmed to loiter until manual control is initiated by a pilot or until the control station operators initiate an emergency

- land sequence.



### Pilot Warnings

Warnings such as low battery, low GPS satellites, low airspeed, low al titude, and loss of communications are relayed to the vehicle operator in Mission Planner. See Appendix 9 for discussion of Mission Planner

software. These are visual flags in the Mission Planner software in the status area of the screen that are readily visible. In addition, all warnings are also issued audibly by the ground station software.



### Severe Weather

Primary weather condition monitoring is handled by the onboard Mission Control Computer. However, it is also possible for an operator to override this behavior at any time, as it is possible for all vehicle operations. In the event that weather conditions arise that approach the operational limits of the vehicle, the vehicle will be commanded to fly home immediately, or the operators or pilots will immediately resume manual control of the vehicle and initiate a recovery sequence.

## Appendix 4

– Ground Control Station Background

General:

The ground control station will include a single computer in communications contact with the vehicle system. This station will primarily act as an information conduit to the operators with little manual control as the normal vehicle operations will be full y autonomous. However, the capability to manually regain control of the vehicle and operate the system will always be available as an option and fail

- safe measure.



## Control Method

The vehicle can be controlled in either full autonomous mode or in manual mode as required.

Fully autonomous control of the aircraft, the nominal mode of operations for the HawkEye system, utilizes the Mission Control Computer to undertake the flight path generation functions, payload control, and determining optimal landing a nd recovery paths. This also includes diagnostics and threshold monitoring during operations. Unmanned control of the vehicle also includes preprogrammed flight specified by waypoints and commands from users through Mission Planner ground control station s oftware. The vehicle is able to autonomously maintain stability through the onboard 3D Robotics’ APM 2.6 Autopilot. While in autonomous control, the user may also use the RC hand controller to augment the control commands sent by the autopilot.

A Futaba

- compatible RC transmitter (RC hand controller) is used to provide remote control capabilities and manual override for the vehicle. In this case, the pilot has direct control of the aircraft’s flight control surfaces.



## Data Links

There are two independent communications links on the HawkEye Aircraft Platform: a 915 MHz radio transceiver with an unobstructed broadcast range of 2 km for communicating to Mission Planner software through the CommBox as well as a high bandwidth wire less Ethernet link (2.4 GHz) for the additional onboard CPU.



## Ground Control Station Instrumentation

The vehicle can be monitored through the management program located on the ground station. This is the 3D Robotics’ open

- source flight management software : M ission Planner. Mission Planner ground station software receives and displays status information from the vehicle. It provides a graphical interface with a map display for users with simple access to retrieve this information.

Note that while the autopilot software is an open

- source product (meaning that the user community is free to
modify the hardware and software), PrecisionHawk has extensively tested one version of the software that is used
on every Aircraft system. PrecisionHawk routinely evaluates and tests new versions of the autopilot software, but
they are never released into production until vetted by the hardware and software teams. Once a new version of
autopilot software is approved by the PrecisionHawk production team, the aircra ft is programmed to prevent flight
unless the specific approved autopilot firmware is running on the aircraft.

The final function of the Ground Station is to provide an Emergency Stop function.



## Launch, Takeoff and Recovery Methods

Currently launch and ta ke off are executed in the following manner:

1. Vehicle is inspected

2. System start

- up and diagnostics are run for sensors

3. Takeoff settings are uploaded to FCC from the MCC

### Page | 46 4. User inputs and survey parameters are checked for consistency and to ensure they fall wi thin operating ranges, performance and limits of the aircraft

5. Avionics data and information are confirmed as operating normally

6. Motors and power systems are initialized, confirmed and engaged

7. Vehicle is launched and UAV mode is set to takeoff

8. Vehicle shoul d follow predefined takeoff settings, lift to desired altitude and approach programmed takeoff point

9. Control of the vehicle is either maintained by the pilot or control station operator, or the launch takes place

under autonomous control. This determinatio n is made prior to launch.

10. Since the operations are to generally be fully autonomous, the MCC commands the aircraft into a series of maneuvers to determine the current weather conditions at flight altitude

11. Since the operations are to generally be fully autonomous, the MCC determines a mission flight path based

on the current conditions

, and the aircraft flies according to the MCC commands

Landing is performed in the following manner:

1. Since in normal operations the landing will be fully autonomous, the MCC computes an optimal landing and approach path based on current weather conditions

2. In emergencies, if the landing is under manual or user control, landing settings are uploaded to FCC

3. Vehicle is commanded to switch to the Landing mode when directed by t he PIC.

4. Vehicle approaches landing site autonomously according to predefined settings

5. Vehicle reduces altitude until touch

- down

6. Vehicle motors are stopped

7. Avionics processes are halted

8. Vehicle is recovered ; motor is disabled.



## Redundant Ground Control Station Systems

The ground station currently includes Mission Planner, a terminal window, and the PrecisionHawk Base Station software to control and monitor the onboard CPU, and also the manual control capability of the vehicle from the pilot. These can be run or utilized independently and can communicate to the aircraft independently.



## Communication Rates

Currently, the system relays its state (orientation and flight status) every 0.2 seconds from both the Mission Planner and the onboard CPU, and the cur rent position and target heading and flight command every 0.5 seconds. In the event that faster update rates are required, specific sensors or information packets can be queried at much higher rates (100 Hz).

### Page | 47 

## Appendix 5

– Communications Background

The communication links and protocols between the UAV and Mission Planner are enabled through the communication device (Commbox). It allows operators to monitor, issue commands and upload flight plans to the autopilot. The wireless communication link uses ra dio frequencies operating at 915 MHz with an outdoor LOS range up to 2 km.

Communication links from the autopilot and additional onboard CPU utilize a communication protocol known as
“MAVLink”. This standard protocol (shared by several autopilot manufact ure r s) includes full vehicle state
information and allow for full vehicle control or autonomous operations.

### Page | 48 

## Appendix 6

– Payload Background

Three potential payloads have been identified for use with the HawkEye aircraft: a visual camera, a multispectral
agricultural camera, and a thermal camera.

Currently, integration with the visual and multispectral cameras ha s been completed. All cameras have a maximum

mass under 0.66 lbs. (300 g).

### Page | 49 

## Appendix 7

– Security Plan Background

The following provides an overview of the Security Plan. The Flight Operations Manual paragraph “Sterile Area/Airspace Control” is contro lling and should be consulted prior to each operation.

The aircraft will be kept within visual contact of the pilot on the ground at all times. There will be two failsafe operations options during any flight session with an autonomous controller:

1. O nboard autopilots to put the UAVs into a predetermined path through the ground station control software should the autonomous controllers fail; or

2. Manual control take over by pilot on the ground through RC in the case where both the formation controller and pred etermined path autopilots fail

The flights planned will not take place over members of the public, buildings, or vehicles other than th ose involved in UAV operations.

Spectators are not expected during system operations. Any casual spectators that appear during the flight sessions or spectators specifically invited by the PrecisionHawk Inc. to view UAV demonstrations will be required to keep clear from the operational aircraft by using barriers or indicators such as pylons and per the guidelines in the Fl ight Operations Manual.

It will be the responsibility of the flight crew to ensure sufficient separation is imposed between the operation area and the spectators if there are any. If this action is not possible, the flight operations will be halted unt il the safe separation criteria is achieved.

No flight tests are schedule d to operate in any locations or at any altitudes where permission is required from airport authorities. Operations are also not expected to take place in any area where persons other than the property owners will need to be notified and consulted. Furthermore, the UAVs will not be expected to operate in areas where the public will have to be removed from areas affected by the operations.

Finally, the location choice for the base of operations will be made accessible to emergency vehicles in case they
are required.

### Page | 50 

## Appendix 8

– Emergency Contingency Plan Background

The vehicle is a foam aircraft that consists of small electric motors and components, so the risks to persons or property should be minimal. However, contingency planning will be required in the cases of:

1. Medical needs from vehicle crashing or loose prope llers

2. Fire in the ground station or vehicle electric components

If any of the above events do occur, immediate assistance will be provided through medical first aid and fire extinguisher. If further assistance or help is required, a cellular phone will be available to contact emergency personnel. Thus, a first aid kit, fire extinguisher and cellular phones will be present at the time of flight operations.

In the event of more serious injuries, the first to be contacted will be emergency services. If they are unable to respond, the next option will be to take the injured person to the closest hospital, while still trying to contact the emergency services along the way. All these emergency contact numbers will be identified and presented to all

crew members before the flight operations.

As the flight operations for the vehicle will typically be on the order of 30

- 100 m AGL, there is little risk to general
airspace users. Further care will be taken, however, to remain clear of areas where low flying aircraf t could be operating. This will include review NOTAMs relevant to the operational areas and dates/times.

## Appendix 10

– Using the Flight Planning Software

The PrecisionHawk Mission Planning software is user

- friendly.

Step 1: Install Mission Planning Software onto computer using the provided USB. If a Field Laptop was purchased,
the Mission Planning Software will already be installed onto Desktop.

Step 2: Open the Mission Planning Software by searching for its saved location a nd double

- clicking on the icon.

Step 3: Upon opening the Mission Planner for the first time, the system will prompt you to choose the location of

a Micro

- SD card. Insert the Micro

- SD card included with the Aircraft into the USB adapter. Plug the USB adap ter into the USB port on the laptop. Once a Micro

- SD card has been identified, choose it on the prompt.

Step 4: Once you have chosen the micro

- SD card, a configuration file from the software will automatically be saved
onto the card. All missions planned hereafter will be saved into this location (unless otherwise specified).

Step 5: Next, click on the "New Plan" icon to start planning your mission. The plan will automatically be named
"Untitled". You may change the name of the flight plan by clicking "E dit" next to the name.

### Page | 54 Step 6: Once the new mission has been created and named, you will choose if you would like to perform a

bounded or linear survey.

Bounded Survey: A bounded survey consists of selecting a 2 dimensional area (unlimited sides of the shape) in
which you would like to survey. Rather than flying a straight line (as a linear survey does), the plane will determine
the most efficient way to build transects to collect data within the bounded area

First, find the location of the area you would like to survey. This can be done a few different ways. Either type in
the address in the "Address Bar" at the top of the screen, or by zooming out on the map using the scale, moving
over, and zooming into the area you wish to survey on the world map (Precision Hawk Mission Planner uses
Google Maps API)

### Page | 55 To help identify specific landmarks, you may also choose Satellite Mode, which will show you visual imagery of the

area in focus.

If you know the specific GPS coordinates that you are trying to s urvey, you may manually input them.

GPS coordinates will automatically populate the Latitude and Longitude boxes when a point is selected on the map
by left clicking.

### Page | 56 Second, begin mapping out the survey area by left clicking on points on the map or manually entering the first and
second GPS point.

Once completed, you will see a dot in the middle of these two plotted point. Left click and hold while moving your
mouse. This will allow you to "stretch the area out into a triangle shape. You can use this method on any of the
"between dots" to now stretch the shape into a 4

- sided, 5

- sided, 6

- sided (unlimited sided) shape. Once you have
outlined your shape, you may then left click and drag on the middle of the shape to move the entire shape around

on th e map.

Linear Survey: This type of survey consists of flying from GPS point to GPS point. To perform a linear survey, you
must first find the location you would like to survey on the map. Do this using one of the methods as listed above
in "Bounded Survey" . After choosing the location where you would like to start the survey, continue adding

### Page | 57 waypoints. Mission Planner will connect each point to the previous point using strait lines. The aircraft will conduct
its survey by flying to each point on these lines in the order that they were chosen.

Step 6: Once your survey area has been determined, you have the option of choosing either the Ground
Resolution or the Altitude for the survey. These two options are inversely related; the higher resolution you choose
to collect, the lower the altitude will be, and the higher the altitude you choose, the lower the ground resolution
will be. You can make this choice by left clicking on either the "Ground Resolution" or "Altitude" icon and moving

the horizontal sca le right or left by left clicking and holding while moving the mouse left or right.

Note: The maximum altitude for a flight is set at l00 m, as to not disrupt the manned airspace

You can also specify by Altitude.

### Page | 58 As the mission planner cannot determin e which sensor you plan to use until you are in the field (the payload bay is
intelligently queried when it connects), you can look at the right column of the screen which displays the altitude
and ground resolution for each sensor. These numbers dynamical ly change as you make changes to the horizontal

Ground Resolution or Altitude scale.

Once you've set your flight plan, left click on "Activate Flight Plan." This will automatically save your mission to the
Micro SD card that you've chosen when you opened the program. This Micro SD card will then be physically
removed from the computer, inserted into the plane, and act as the brains (it gives the parameters) for the flight.

Edit Mission Name: If you would like to change or edit the name of your mission, select (left click) the mission, then

left click on "Edit.”

### Page | 59 Save to New SD Card: If you would like to save a plan to a different Micro SD Card than originally chosen, left click

on "New SD Card" and the file location screen will occur.

### Page | 60 Delete Miss ion: If you would like to delete a mission, select (left click) the mission and left click on "Delete.”

## Appendix 11

– Maintenance Log s

General: Any damage or worn out parts need to be replaced or repaired before the next flight. Log books are not
only used to record flight times with a running total, but also to record all maintenance items as well. Each aircraft

will have its own identifying number and a corresponding log book. The log book will be kept with the aircraft and
entries made including flight times, conditions, parts that are replaced

, airworthiness testing

, and any other notes
of interest related to perfo rmance.

Information in the log books is valuable to assess any problems and can assist in preventative solutions for future
flight to avoid similar issues. Examples of PrecisionHawk Logs follow:

## Appendix 12

– Takeoff, Cruise/Survey, and Re covery Methods Overview

General

The following provides an overview of the various methods the Lancaster utilizes for Launch, Takeoff,
and Recovery.

Currently Launch and take off are executed in the following manner:

1. Vehicle is inspected.

2. System start

- up and diagnostics are run for sensors.

3. Flight settings are uploaded to the autopilot from the field computer.

4. User inputs and survey parameters are checked for consistency and to ensure they fall within operating ranges, performance, and limits of the aircr aft.

5. Avionics data and information are confirmed as operating normally.

6. Motors and power systems are initialized, confirmed and engaged.

7. Vehicle is launched and UAV mode is set to takeoff.

8. Vehicle should follow predefined takeoff settings, climb to desire d altitude, perform survey, approach the predefined landing point

, and finally land.

### Page | 70 

## Takeoff Expanded

Step 1

With Mission Planner open, the Futaba
radio powered on and the ground

communication box connected and
powered on, open the battery hatch and
insert the flight battery into the bottom of

the airframe.

Step 2

Secure the battery and make sure the grab
catches have mated properly. Close the battery

hatch.

Step 3

On the top right hand side of Mission Planner, choose the “COMxx” port from the drop down

menu and set the baud rate to 115200. After pressing connect (found on the top right hand side), the signal strength between the plane and the MCC will be shown on the top left hand panel of Mission Planner confirming the communication

b etween Mission Planner and the aircraft.

Step 4

Set the aircraft where you would like it to land on flat, level ground. Select the flight plan using the up and down buttons and press "Ok/Launch" on

the left side of the airframe. The aircraft will wait to acquire GPS, home itself to this position in Mission Planner, perform diagnostics check, and zero its pressure sensors.

### Page | 71 Step 5

The LCD indicates that the aircraft will begin to perform preflight tests. The tests are in order : 1)

GPS lock

, 2) Control surface test

, 3) Sensor

calibration

, 4) Airspeed test , and 5) R/C transmitter test. Keep in mind that for test 3, the plane has to be level and the pitot tube must be

covered.

Step 6

Within the flight plan tab of Mission Planner,

click “Read WPS” to confirm survey area and takeoff loiter location (WP 2). Also make sure the landing touchdown location (last WP) is correctly set. If any changes are made, click “Write WPS” to upload changes to aircraft.

Step 7 The aircraft is now ready to fly. Pick it up in your throwing hand. When ready to launch, press "OK/Launch" button on the left hand side of the airframe. A 5 second countdown will begin as indicated by the LCD. Tilt the aircraft so that the nose is pointing towards the ground. Af ter the countdown, tilt plane up. The motor will spin to full power. Give the aircraft a gentle, strai gh t,
level toss.



## Cruise/Survey Expanded

Step 1
The aircraft will continue in Take

- off mode, climbing to its survey altitude and proceeding

with loit ering around “WP 2” in order to

determine the wind direction. After the aircraft has measured the wind parameters, It will calculate a survey path to cover the area between the designated box. In the Flight Plan tab, click “Read WPS” to download the flight pattern.

### Page | 72 Step 2 Once the flight path has been downloaded it will appear over the map in Mission Planner. Verify

that it has built the correct transects over the selected area. While it flies on its track, monitor its airspeed, altitude, flight path, and battery voltage (over 10.6 Volts).

Step 3 When the aircraft completes its survey, it will automatically initiate the landing sequence. It will also initiate the landing if the flight battery voltage drops below 10.6 Volts. The final

way point indicates the landing point.

### Page | 73 

## Landing Expanded

Landing principles are as follows:

1. If the landing is to be fully autonomous, the autopilot computes an optimal landing and approach path based on current weather conditions.

2. If the landing is under manual or user control, landing settings are uploaded to autopilot

. 3. Vehicle is commanded to switch to Landing mode when landing is desired by the PIC.

4. Vehicle approaches landing site autonomously according to predefined settings.

5. Vehicle approache s landing waypoint and circles to correct landing direction (around the second to last waypoint). In addition, it will drop to an altitude of 40 meters at this stage.

6. Vehicle reduces altitude until touch

- down.

7. Vehicle motors are stopped.

8. Avionics process es are halted.

9. Vehicle is recovered, motor is disabled.

Step 1 The aircraft will begin to approach the landing point from the second to last waypoint. From this point, a n 820 ft. ( 250 meter ) landing path is made in which the aircraft will gradually

dec rease altitude from 131 ft. ( 40 meters ) to ground. Before the aircraft initiates its landing sequence, ensure that the aircraft will not be passing any obstacles from the landing approach to landing waypoints.

Step 2 Monitor the aircraft both visually and from Virtual Cockpit as it continues on its landing path. The pilot may take over manual control if it gets too low or in a dangerous position

. Otherwise , it will continue and land itself

.

St ep 3 After the aircraft has landed on the ground, approach it with caution. Lift the plane up and

hold the button labeled with an arrow for 10 seconds to power down the aircraft. You may

now disassemble and remove the sensors and

data from the aircraft.
