Flight Control and Navigation System

The ight control and navigation system built into the aircraft has modules such as the ight controller, IMU, barometer, GNSS receiver, RTK module, and a compass, providing stable and reliable navigation and control. The dedicated industrial ight controller provides multiple operation modes for various applications. The GNSS+RTK dual-redundancy system is compatible with GPS, GLONASS, BeiDou, and Galileo. The aircraft also supports centimeter-level positioning when used with the built-in onboard RTK antennas.

Aircraft RTK

When the aircraft is used with the RTK module of the dock, centimeter-level positioning data can be obtained, allowing for a precise ight route and landing.

Users can choose dierent positioning accuracy when making task plans in DJI FlightHub 2:

• RTK: The aircraft will take o and wait for the RTK data to converge before performing a task. It is unable to pause the task during convergence. It is recommended to choose this task when high positioning accuracy is required.

• GNSS: The aircraft will perform a task directly without converging RTK data. It is recommended to choose this task when basic positioning accuracy is acceptable. Make sure that there are no obstacles within 20 meters along the ight route before initiating the task plan.

• The number of searched satellites should be greater than 20 for the aircraft RTK data to converge. If there is strong signal interference or ionospheric scintillation, the aircraft RTK data may not converge.

• The RTK positioning needs to be done in an environment with a strong GNSS signal (outdoors in an open area without obstacles) to ensure high-precision positioning. The RTK solution is xed to converge to centimeter-level accuracy.

• Make sure the dock RTK is calibrated before an RTK task to ensure accurate ight along the ight route.

• If the aircraft RTK type is switched (for example switched to the network RTK using the remote controller then linked the aircraft and the dock), make sure to restart the aircraft before performing ight tasks.

Quick Takeo

When the aircraft is used with the dock, quick takeo can be achieved. The aircraft can quickly take o and perform ight tasks without waiting for the aircraft RTK data to converge. Quick Takeo can be achieved in DJI FlightHub 2:

DJI Dock 2/Matrice 3D Series Unmanned Aircraft Flight Manual

• Click Takeo in the device status window after gaining aircraft control.

• Select the positioning accuracy as GNSS in the Task Plan Library.

• Quick Takeo is only available when the dock has network connection and the network signal is strong.

Communications Equipment

The aircraft boasts DJI O3 Enterprise video transmission system with OcuSync video transmission antennas, oering stable and reliable communication with the control station.

Vision System and Infrared Sensing System

The aircraft is equipped with an infrared sensing system and a vision system, allowing for vision positioning and six-direction obstacle sensing.

• To ensure a safe and steady ight, DO NOT block the vision and infrared sensors.

• Clean the lenses of the vision and infrared sensing systems on a regular basis. If the vision sensor lenses are blurry, a warning will appear in DJI FlightHub 2 during ight tasks. Clean the lenses as soon as possible after the warning appears.

After landing, the propellers will slowly rotate for a few seconds. During the rotation process, the aircraft will check the integrity of the propellers using the vision system. There will be a warning prompt if any propeller error occurs and the aircraft cannot takeo to ensure ight safety. The following conditions are required for propeller vision detection:

• DJI Matrice 3D Series propellers are used.

• In daytime when the lighting is sucient.

• No vision system warnings in DJI FlightHub 2.

DJI Dock 2/Matrice 3D Series Unmanned Aircraft Flight Manual

• The aircraft is about to take o before a ight route task.

• The propelleres are clean.

• There are limitations of the vision detection function for the propellers. DO NOT completely rely on the vision system functions.

• When a propeller error warning appears in DJI FlightHub 2, check whether the propellers are clean and not damaged. Clean the propellers if there is any noticeable build-up or replace damaged propellers and then restart the aircraft before performing a ight task.

DJI AirSense

Crewed airplanes or helicopters with Automatic Dependent Surveillance–Broadcast (ADSB) transmitters can broadcast ight information. The DJI aircraft equipped with DJI AirSense can receive the ight information broadcast from ADS-B transmitters that comply with the 1090ES (RTCA DO-260) or UAT (RTCA DO-282) standard and within a radius range of 10 km. DJI AirSense only issues warning messages under certain circumstances when specic crewed airplanes or helicopters are approaching and are not able to actively control or take over the DJI aircraft to avoid collisions. DJI AirSense has the following limitations:

1. DJI AirSense can only receive messages broadcast by crewed airplanes or helicopters installed with an ADS-B Out device that is in compliance with the 1090ES or UAT standard. DJI AirSense cannot receive messages from crewed airplanes or helicopters that are not equipped with ADS-B Out devices or equipped with devices that are not functioning properly.

2. DJI AirSense uses satellite and radio signals to receive ADS-B messages. If there is an obstacle between a crewed airplane or helicopter and a DJI aircraft, DJI AirSense may not be able to receive broadcast and issue warning messages.

3. Warning messages may be sent with a delay if DJI AirSense experiences any interference from the surrounding environment. Users need to observe the surrounding environment and y with caution.

4. Warning messages may not be accurate when the DJI aircraft is unable to obtain its location information.

5. DJI AirSense cannot receive broadcast from crewed airplanes or helicopters, nor send warning messages to DJI FlightHub 2 users when DJI AirSense is disabled or not properly functioning.

DJI FlightHub 2 collects all the DJI AirSense data reported by the dock aircraft in the project and displays the location of an approaching crewed airplane or helicopter, as well as a warning message on the web page when there is a potential risk of collision. DJI

DJI Dock 2/Matrice 3D Series Unmanned Aircraft Flight Manual

AirSense can obtain and analyze the location, altitude, orientation, and velocity of the crewed airplane or helicopter and compare the information with the current location, altitude, orientation, and velocity of the dock aircraft to evaluate the collision risk in real time.

• Warning (high collision risk): A red airplane icon will appear on the map, and the web page will display the message stating, “Crewed aircraft nearby. Take over aircraft promptly to avoid”. DJI FlightHub 2 users can click the dock name to open the device status window and obtain control of the aircraft to avoid collisions.

• Caution (medium collision risk): A yellow airplane icon will appear on the map when a crewed airplane or helicopter is relatively near the dock aircraft.

• Normal (low collision risk): A blue airplane icon will appear on the map when the crewed airplane or helicopter is relatively far away from the dock aircraft.

• Users can click in the lower right corner of the map to decide whether to display the low and medium collision risk warnings on the map.

Flight Restrictions and Unlocking

Geospatial Environment Online (GEO) System

The DJI Geospatial Environment Online (GEO) System is a global information system that provides real-time information on ight safety and restriction updates, and prevents UAVs from ying in restricted airspace. Under exceptional circumstances, restricted areas can be unlocked to allow ight. Prior to that, the user must submit an unlocking request based on the current restriction level in the intended ight area. The GEO System may not fully comply with local laws and regulations. Users shall be responsible for their own ight safety and must consult with the local authorities on the relevant legal and regulatory requirements before requesting to unlock a ight in a restricted area.

GEO Zones

DJI's GEO System designates safe ight locations, provides risk levels and safety notices for individual ights and oers information on restricted airspace. All restricted ight areas are referred to as GEO Zones, which are further divided into Restricted Zones, Authorization Zones, Warning Zones, Enhanced Warning Zones, and Altitude Zones. GEO Zones include but are not limited to airports, venues of major events, areas where emergencies have occurred (such as forest res), nuclear power plants, correctional facilities, government facilities, and military zones. Users can view real-time GEO information in DJI FlightHub 2.

By default, the GEO System limits takeo and ight in zones that may cause safety or security concerns. A GEO Zone map that contains comprehensive information on GEO Zones around the globe is available on the ocial DJI website: https://y-safe.dji.com/nfz/

nfz-query.

The settings and alerts provided by DJI on operations within GEO Zones are only to assist the user in ensuring ight safety and DO NOT guarantee full compliance with all local laws and regulations. Before each ight task, the user is responsible for seeking advice on the relevant local laws, regulations, and requirements for the safety of the aircraft.

Flight Restrictions in GEO Zones

The following section describes in detail the ight restrictions for the above-mentioned GEO Zones.

DJI Dock 2/Matrice 3D Series Unmanned Aircraft Flight Manual

Please view GEO information in DJI FlightHub 2 and stay alert.

The dock aircraft cannot take o, and a prompt will appear in DJI FlightHub 2 when the planned ight altitude exceeds the maximum altitude of the aircraft.

Buer Zone

Buer Zones for Restricted Zones/Authorization Zones: To prevent the aircraft from accidentally ying into a Restricted or Authorization Zone, the GEO System creates a buer zone of about 20 meters wide outside each Restricted and Authorization Zone. As shown in the illustration below, the aircraft can only take o and land away from the Restricted or Authorization Zone when inside the buer zone. The aircraft cannot y toward the Restricted or Authorization Zone unless an unlocking request has been approved. The aircraft cannot y back into the buer zone after leaving the buer zone.

Buer Zones for Altitude Zones: A buer zone of about 20 meters wide is established outside each Altitude Zone. As shown in the illustration below, when approaching the buer zone of an Altitude Zone in a horizontal direction, the aircraft will gradually reduce its ight speed and hover outside the buer zone. When approaching the buer zone from underneath in a vertical direction, the aircraft can ascend and descend in altitude or y away from the Altitude Zone. The aircraft cannot y toward the Altitude Zone. The aircraft cannot y back into the buer zone in a horizontal direction after leaving the buer zone.

• To ensure ight precision, when importing ight routes to DJI FlightHub 2, make sure the RTK signal source of the ight route is the same as the signal source used to calibrate the dock RTK. Otherwise, the actual ight trajectory of the aircraft diers from the preset ight route, and may even cause the aircraft to crash.

• After a task plan is initiated, the dock will automatically check whether the environment (such as wind speed, rainfall, and temperature) is suitable for ight tasks. To ensure ight safety, the aircraft cannot take o in the following conditions:

◆

The wind speed is above 8 m/s.

◆

The rainfall exceeds 2 mm/hour.

◆

The Intelligent Flight Battery level is below 30%.

◆

The aircraft satellite signal is weak (the aircraft satellite icon in DJI FlightHub 2 is red).

◆

The battery lifespan is reached.

◆

Dock cover error occurs.

◆

The rmware of the dock and the aircraft are not compatible. Make sure to update the rmware of the dock and the aircraft to the latest version before performing a ight task.

• In the following scenarios, the dock and the aircraft cannot perform a multi-dock task:

◆

The distance between the docks for takeo and landing is more than 15 km.

◆

The dock for takeo or landing is not in idle status.

◆

The rmware of the docks are not updated to v10.01.16.04 or above.

◆

The dock locations are not re-calibrated before performing a multi-dock task.

◆

The aircraft RTK is not xed.

• If the positioning accuracy is selected as RTK in Task Plan Library, the aircraft will take o and wait for the RTK to converge before performing a ight task. The aircraft will land on the dock if the RTK fails to converge.

• If a warning message appears in DJI FlightHub 2, click the message to view warning details, and follow the instructions to perform remote debugging.

• Try lowering the ight altitude and the RTH altitude to reduce the eect of a strong wind condition. Meanwhile, check the ight altitude and the RTH altitude to ensure there are no obstacles during ight or RTH.

Calibrating the Dock RTK

The dock integrates dual RTK antennas, allowing for centimeter-level positioning when used with DJI Matrice 3D Series aircraft.

To ensure ight route accuracy, make sure the dock RTK is calibrated before an RTK ight task. The dock RTK data is already calibrated using the remote controller during dock conguration, and does not require recalibration if the dock location remains the same. If

DJI Dock 2/Matrice 3D Series Unmanned Aircraft Flight Manual

the dock is moved, recalibrate the dock location in DJI Pilot 2 using the remote controller. Refer to the Installation and Setup Manual for more information.

• Make sure the landing pad is clear of obstacles and that the RTK antennas are not covered. Otherwise, the signals will be obstructed and the positioning performance will be aected.

• When setting the alternate landing site or performing RTK tasks, DO NOT move the dock position, restart the dock, or recalibrate the dock position.

• Increased ionospheric activity or scintillation may aect the accuracy of RTK positioning. In this case, it is not recommended to calibrate the dock position.

• Users can open the DJI FlightHub 2 project page, click > > Action to view the dock RTK status.

Connecting the Remote Controller as Controller B

To ensure ight test safety, the remote controller can be used to take control of the aircraft manually during on-site ight tests after connecting to the aircraft as controller B. Link the remote controller to the aircraft as controller B following the steps below:

1. Power on the remote controller and the aircraft.

2. Run DJI Pilot 2, select Matrice 3D Series in the homepage.

distance and the warning distance. Default values are recommended.

b. Gimbal Settings: Perform Gimbal Auto Calibration by following the instructions.

c. RTK Module: Make sure Maintain Positioning Accuracy is enabled.

Calibrating the Aircraft

Calibrating the Aircraft Compass

Calibrate the compass when prompted to do so in DJI Pilot 2 or DJI FlightHub 2, or when the status indicator blinks red and yellow alternately. Observe the following when calibrating the compass:

• DO NOT calibrate the compass in locations with strong magnetic interference, such as near magnets, parking lots, or construction sites with underground reinforced concrete structures.

• DO NOT carry ferromagnetic materials such as mobile phones during calibration.

• DJI Pilot 2 will display a prompt if the compass is aected by strong interference after calibration is complete. Follow the on-screen instructions to resolve the compass issue.

• If a compass interference prompt appears in DJI FlightHub 2 or DJI Pilot 2, the aircraft cannot take o. Calibrate the compass as soon as possible to ensure the ight performance of the aircraft.

• It is recommended to calibrate the compass before taking o in the following scenarios: taking o for the rst time after the aircraft has been stored for an

DJI Dock 2/Matrice 3D Series Unmanned Aircraft Flight Manual

extended period of time, taking o after being placed near strong magnetic objects, or taking o at night.

Calibration Procedure

Perform the calibration in an open area, link the aircraft to remote controller B and gain aircraft control, and then follow the steps below to complete the calibration.

1. Run DJI Pilot 2 and enter the camera view on the home screen. Tap

> > Sensor

Status > Compass, and tap Calibrate Compass to start the calibration. The aircraft

status indicator will be solid yellow to indicate calibration has started.

2. Hold the aircraft horizontally 1.5 m (4.92 ft) above the ground and rotate the aircraft 360 degrees around the center axis. The aircraft status indicators will be solid green.

3. Hold the aircraft vertically as shown in the gure, and rotate the aircraft 360 degrees around the center axis.

4. Re-calibrate the aircraft if the aircraft status indicators blink red.

• If the aircraft status indicator blinks red and yellow alternately after calibration is completed, this indicates the current location is unsuitable for ying due to the level of magnetic interference. Choose a new location.

• A prompt will appear in DJI Pilot 2 if compass calibration is required before takeo. The prompt will disappear after the calibration is complete.

• If the prompt appears again in DJI Pilot 2 when placing the aircraft on the ground after calibration, try moving the aircraft to a dierent location.

3.8 Takeo/Landing

Automatic Takeo/Landing

The dock cover opens after initiating a ight task, and the aircraft takes o from the dock. Once the aircraft takes o, the dock cover will close and the aircraft will begin to perform the ight task.

After completing the ight route, the aircraft ies above the dock, and the dock cover automatically opens to allow the aircraft to land. After the aircraft lands, the dock cover automatically closes.

Manual Takeo/Landing

The remote controller can be used to control the aircraft manually during on-site ight tests. The Combination Stick Command (CSC) listed below is used to start and stop the aircraft motors.

Takeo

Perform a Combination Stick Command (CSC) as shown below to start the motors. Once the motors have started spinning, release both sticks simultaneously. Gently push the throttle stick up to take o.

Take o immediately once the motors are spinning. Otherwise, the aircraft may lose balance, drift, or even take o by itself which may risk causing damage or injury.

Landing

To land, push the throttle stick down to descend until the aircraft touches the ground. There are two methods to stop the motors:

Method 1: When the aircraft has landed, push the throttle stick down and hold until the motors stop.

DJI Dock 2/Matrice 3D Series Unmanned Aircraft Flight Manual

Throttle Stick (Left stick in Mode 2)

Method 2: Push the throttle stick down, and perform the same CSC that was used to start the motors. Release both sticks once the motors have stopped.

• Spinning propellers can be dangerous. Stay away from spinning propellers and motors. DO NOT start the motors in conned spaces or where there are people nearby.

• Maintain control of the remote controller as long as the motors are running.

• DO NOT stop the motors mid-ight unless in an emergency situation where doing so will reduce the risk of damage or injury.

• It is recommended to use Method 1 to stop the motors. When using Method 2 to stop the motors, the aircraft may roll over if it is not completely grounded. Use Method 2 with caution.

• After landing, power o the aircraft before turning o the remote controller.

Flight Route Tasks

DJI FlightHub 2 provides ight route and task plan management. Users can create and edit ight routes in Flight Route Library, and designate ight routes and create task plans in Task Plan Library based on their actual needs. The aircraft will take o automatically according to the ight route and the preset Plan Timer.

Go to the DJI FlightHub 2 User Guide for more information on editing ight routes and planning ight route tasks.

Live Flight Controls

DJI FlightHub 2 supports sending commands directly to the aircraft that is bound to the dock and remotely operating the aircraft. Go to the DJI FlightHub 2 User Guide and refer to the “Live Flight Controls” section for more information.

DJI Dock 2/Matrice 3D Series Unmanned Aircraft Flight Manual

On-site Flight Controls

The remote controller can be used to control the aircraft manually during on-site ight tests after gaining aircraft control. The control sticks can be operated in Mode 1, Mode 2, or Mode 3, as shown below.

Mode 1

Mode 2

Mode 3

The default control stick mode of the remote controller is Mode 2. Run DJI Pilot 2 and enter the camera view, tap > to modify the control stick mode for the remote controller.

DJI Dock 2/Matrice 3D Series Unmanned Aircraft Flight Manual

Flight Modes

The aircraft supports N mode (Normal), S mode (Sport), and F mode (Function), and the aircraft ies in N mode by default.

Flight modes can be switched using the remote controller B after taking aircraft control.

The aircraft only supports N mode when used with the dock.

Normal Mode

In N mode, the aircraft uses GNSS to locate and stabilize itself when the GNSS signal is strong. When the GNSS is weak, but the lighting and other environmental conditions are sucient, it uses the vision system. When the obstacle sensing is enabled and the lighting is sucient, the maximum tilt angle of the aircraft is 25°, and the maximum forward ight speed is 15 m/s.

Sport Mode

In S mode, the aircraft uses GNSS for positioning and the aircraft is more responsive to control stick movements. Note that obstacle sensing is disabled and the maximum ight speed is 21 m/s in S mode.

Function Mode

F mode can be set to T-mode (Tripod mode) or A-mode (Attitude mode) in DJI Pilot 2. In T-mode, the aircraft is more stable when taking photos or videos. A-mode must be used with caution.

The aircraft automatically changes to A-mode when the vision system is unavailable or disabled and when the GNSS signal is weak or the compass experiences interference. In A-mode, the aircraft may be more easily aected by its surroundings. Environmental factors such as wind can result in horizontal shifting, which may present hazards, especially when ying in conned spaces. The aircraft will not be able to hover or brake automatically, therefore the user needs to land the aircraft as soon as possible to avoid accidents.

• DO NOT switch from N mode to other modes unless the pilot is suciently familiar with the aircraft behavior under each ight mode. Make sure to enable Multiple Flight Modes in DJI Pilot 2 before switching from N mode to other modes.

• The vision system is disabled in S mode, which means the aircraft cannot sense obstacles on its route automatically. The user must stay alert to the surrounding environment and control the aircraft to avoid obstacles.

• The maximum speed and braking distance of the aircraft signicantly increase in S mode. A minimum braking distance of 30 m is required in windless conditions while the aircraft is ying forward, backward, left, or right.

DJI Dock 2/Matrice 3D Series Unmanned Aircraft Flight Manual

• A minimum braking distance of 10 m is required in windless conditions while the aircraft is ascending and descending in S mode or N mode.

• The responsiveness of the aircraft signicantly increases in S mode, which means a small control stick movement on the remote controller translates into the aircraft moving a large distance. Make sure to maintain adequate maneuvering space when ying with the remote controller.

• When switching the GNSS to the BeiDou satellite positioning system in DJI Pilot 2, the aircraft only uses a single positioning system and the satellite search capability becomes poor. Fly with caution.

3.10 RTH

The Return to Home (RTH) function returns the aircraft back to the dock or the alternate landing site when the GNSS signal is strong. Alternate Landing will be triggered if the dock is not suitable for landing. In this case, the aircraft will y to and land at the alternate landing site.

Flight tasks will be interrupted and RTH will be triggered if any of these situations occur:

• The aircraft approaches the GEO Zones, or the ight distance approaches the maximum distance.

• The GNSS signal becomes weak during a ight route task.

• The user actively triggers RTH in DJI FlightHub 2.

• The Intelligent Flight Battery level is too low.

• If the control signal is lost, Signal Lost Action (Return to Home or Continue Task) will be triggered.

• There is strong wind during a ight route task.

• RTH will be triggered if the motors are overloaded or overheated. Auto landing will be triggered if there is critical motor overheating warning.

• When performing RTK ight tasks, if the ight distance is too far, RTK positioning accuracy may decrease. To ensure ight safety, the ight route task will be interrupted and RTH will be triggered.

• During ight, RTH will be triggered if the dock network connection fails.

• Make sure to set an appropriate RTH altitude when creating a ight task plan. The RTH altitude should be at least 5 m lower than the altitude limit of the Altitude Zone.

• During RTH, the aircraft will exit RTH when the GNSS signal becomes weak (the icon becomes red), or the GNSS is unavailable.

DJI Dock 2/Matrice 3D Series Unmanned Aircraft Flight Manual

• GEO Zones may aect the RTH. Avoid ying near GEO Zones.

• The aircraft will exit RTH and hover if the lighting and environment conditions are insucient to complete RTH, even if the vision system is working properly.

Advanced RTH

Advanced RTH can be triggered in three ways: the user actively triggers, the aircraft has low battery, or the control signal is lost. When Advanced RTH is triggered, the aircraft will automatically plan the best RTH path, which will be displayed in DJI FlightHub 2 and will adjust according to the environment.

The user can cancel RTH after gaining aircraft control in DJI FlightHub 2. RTH can also be cancelled by pressing the Flight Pause button or the RTH button on remote controller B after gaining aircraft control. After exiting RTH, users will regain control of the aircraft.

Trigger Method

The user actively triggers RTH

Advanced RTH can be initiated by clicking Return to Home in the device status window in DJI FlightHub 2. During on-site ight tests, advanced RTH can also be initiated by pressing and holding the RTH button on the remote controller after gaining aircraft control.

Aircraft low battery

To avoid unnecessary danger caused by insucient battery power, the aircraft automatically calculates if the battery power is sucient to return to the Home Point according to the current position, environment, and ight speed. The ight task will be interrupted and RTH will be triggered when the battery level is low and only enough to complete an RTH ight.

Users can click Cancel RTH in the device status window to exit RTH. The aircraft will not trigger low battery RTH again if RTH is cancelled. If RTH is cancelled following the warning, the battery may not have enough power for the aircraft to land safely, which may lead to the aircraft crashing or being lost.

The aircraft will land automatically if the current battery level can only support the aircraft long enough to descend from its current altitude. Auto landing cannot be cancelled. During auto landing, users cannot control the aircraft movement in DJI FlightHub 2, but can still gain aircraft control using remote controller B to control the horizontal movement and the descent speed of the aircraft during auto landing. If there is sucient power, the throttle stick can be used to make the aircraft ascend at a speed of 1 m/s.

30:17

DJI Dock 2/Matrice 3D Series Unmanned Aircraft Flight Manual

During auto landing, gain control using remote controller B and move the aircraft horizontally to nd an appropriate place to land as soon as possible. The aircraft will fall if the user keeps pushing the throttle stick upward until the power is depleted.

The battery level indicator is displayed in the device status window:

1. Auto landing (Red)

2. Power required to return home (Yellow)

3. Sucient battery level (Green)

4. Estimated Remaining Flight Time

enough for the aircraft to descend from its current altitude.

Estimated Remaining Flight Time

The estimated remaining ight time of the aircraft is based on its current battery level.

The aircraft will land automatically and dock landing detection will be triggered.

• The colored zones and the estimated remaining ight time on the battery level indicator are automatically adjusted according to the current location and status of the aircraft.

Loss of Control Signal

The signal lost action can be set in DJI FlightHub 2:

• In Live Flight Control: Open the device status window, click Flight Settings > On Signal Lost to set the signal lost action to Return to Home, Hover, or Continue.

• In Flight Route Task: Open the Task Plan Library, and click Create Plan to set the signal lost action during a ight route task to Return to Home or Continue Tak.

DJI Dock 2/Matrice 3D Series Unmanned Aircraft Flight Manual

When the signal lost action is set to RTH, the GNSS signal is strong, the Home Point was successfully recorded, and the compass is functioning normally, RTH automatically activates after the control signal is lost for six seconds or above.

When the lighting is sucient and the vision system is working normally, DJI FlightHub 2 will display the RTH path that was generated by the aircraft before the control signal was lost and return to home using Advanced RTH according to the RTH settings. The aircraft will remain in RTH even if the control signal is restored. DJI FlightHub 2 will update the RTH path accordingly.

When the lighting is insucient and the vision system is not available, the aircraft will perform the Original Route RTH procedure. The aircraft will enter or remain in Preset RTH path if the signal is restored during RTH. The Original Route RTH procedure is as follows:

1. The aircraft brakes and hovers in place.

2. When RTH begins:

• If the RTH distance (the horizontal distance between the aircraft and the Home

Point) is farther than 50 m, the aircraft adjusts its orientation and ies backward for 50 m on its original ight route before entering Preset RTH path.

• If the RTH distance is farther than 5 m but less than 50 m, it adjusts its orientation

and ies to the Home Point in a straight line at the current altitude.

• The aircraft lands immediately if it is less than 5 m from the Home Point when

RTH begins.

3. The aircraft lands and the motors stop after reaching the Home Point.

• The aircraft may not be able to return to the Home Point normally if the GNSS signal is weak or unavailable. The aircraft may enter ATTI mode if the GNSS signal becomes weak or unavailable after RTH is triggered by loss of control signal, and the aircraft will hover in place for a while before landing.

• It is important to set a suitable RTH altitude before each ight. Set the RTH altitude in the device status window or in Task Plan Library in DJI FlightHub 2.

• When the lighting is insucient and the environment is not suitable for the vision system, the aircraft cannot avoid obstacles during RTH.

• The aircraft may not be able to return to the Home Point when the wind speed is too high. Fly with caution.

• RTH cannot be triggered when the aircraft is landing.

• Be aware of small or ne objects such as tree branches or power lines or transparent objects such as water or glass during RTH. In an emergency, cancel RTH and control the aircraft manually using DJI FlightHub 2.

DJI Dock 2/Matrice 3D Series Unmanned Aircraft Flight Manual

RTH Procedure

1. The Home Point is recorded. The default Home Point is the dock.

2. Advanced RTH is triggered.

3. The aircraft brakes and hovers in place. When RTH begins:

• If the RTH distance is less than 5 m, the aircraft will y above the dock and land.

• If the RTH distance is farther than 5 m, the aircraft will plan the best path according to the RTH settings, lighting, and environmental conditions.

4. The aircraft will y automatically according to the RTH settings, environment, and transmission signal during RTH.

5. The aircraft begins landing after reaching the dock.

Advanced RTH Settings

RTH settings are available for Advanced RTH. Optimal Route Planning can be enabled in the device status window under Live Flight Controls before taking o. Optimal Route Planning can also be enabled in the Task Plan Library when creating a task plan.

• It is recommended to enable Obstacle Data in DJI FlightHub 2 for the optimal route planning. Go to the DJI FlightHub 2 User Guide and refer to the Map Task Area section for more information.

1. Optimal RTH Path:

• If the lighting is sucient and the environment is suitable for the vision system or Obstacle Data is enabled, the aircraft will automatically plan the optimal RTH path and adjust the altitude according to environmental factors, regardless of the RTH Altitude settings. The optimal RTH path means the aircraft will travel the shortest distance possible, reducing the amount of battery power used and increasing the ight time.

• If the lighting is insucient and the environment is not suitable for vision system and Obstacle Data is disabled, the aircraft will perform Preset RTH path based on the RTH Altitude settings.

2. Preset RTH Path:

Lighting and Environment Conditions

RTH Distance and Altitude

Current alti-

RTH distance is more than 50 m

RTH distance is within 5-50 m

When the aircraft is approaching the Home Point, if the current altitude is higher than the RTH altitude, the aircraft will intelligently decide whether to perform descending while ying forward according to the surrounding environment, lighting, the set RTH altitude, and the current altitude. When the aircraft is above the Home Point, the current altitude of the aircraft will not be lower than the set RTH altitude. Note that

when the lighting is insucient and the environment is not suitable for the vision system, and the Obstacle Data is disabled in DJI FlightHub 2, the aircraft cannot avoid obstacles. Make sure to set a safe RTH altitude and pay attention to the surrounding environment to ensure ight safety.

The RTH plan in dierent environments, RTH trigger methods, and RTH settings is as follows:

tude < RTH altitude

Current altitude ≥ RTH altitude

Suitable for Vision System

The aircraft will plan the RTH path, y to an open area while bypassing obstacles, ascend to the RTH Altitude, and return to home using the best path.

The aircraft will return to home using the best path at the current altitude.

Unsuitable for Vision System

The aircraft will ascend to the RTH altitude, and y to the Home Point in a straight line at the RTH altitude.

The aircraft will y to the Home Point in a straight line at the current altitude.

• Preset RTH path

Warnings

• During Advanced RTH, the aircraft will adjust the ight speed automatically to suit environmental factors such as wind speed and obstacles.

• The aircraft cannot avoid small or ne objects such as power lines or towers. It is recommended to disable Optimal Route Planning. Make sure to set the RTH Altitude higher than all obstacles.

• It is recommended to mark the waypoint with obstacle above as no-return point to ensure the ight safety during RTH.

• DO NOT update the Home Point after gaining control using remote controller B. Otherwise, the aircraft may not return to the dock if the Home Point is updated.

• If the max altitude is set below the current altitude during RTH, the aircraft will descend to the max altitude rst and then continue to return to home.

• The RTH Altitude cannot be changed during RTH.

• If there is a large dierence in the current altitude and the RTH altitude, the amount of battery power used cannot be calculated accurately due to wind speeds at dierent altitudes. Pay extra attention to the battery power and warning prompts in DJI FlightHub 2.

• During Advanced RTH, if the lighting condition and environment becomes unsuitable for the vision system and if Obstacle Data is disabled, the aircraft

DJI Dock 2/Matrice 3D Series Unmanned Aircraft Flight Manual

will perform Preset RTH path. In this case, the aircraft cannot bypass obstacles. Make sure to set an appropriate RTH altitude before performing RTH.

• If the aircraft reaches the altitude limit of the aircraft current location or of the Home Point while it is ascending during Preset RTH path, the aircraft stops ascending and returns to the Home Point at the current altitude. Pay attention to ight safety during RTH.

• If the Home Point location is in an Altitude Zone while the aircraft is outside the Altitude Zone, when the aircraft reaches the Altitude Zone, it will y below the altitude limit, which may be lower than the set RTH altitude. Fly with caution.

• The aircraft will avoid any GEO Zones encountered when it is ying forward during Advanced RTH. Pay attention to ight safety during RTH.

• In rainy or foggy weather, the vision system is unavailable and the RTH route may be inaccurate, which can cause ight safety risks. DO NOT y when it is rainy, smoggy, or the visibility is lower than 100 m.

Dock Landing Detection

Dock landing detection is activated during landing and the procedure is as follows:

1. If dock landing detection determines the dock is suitable for landing, the aircraft will land on the landing pad directly.

2. If the dock is not suitable for landing (when the dock cover fails to open or when the emergency stop button is pressed), the aircraft will y to the alternate landing site. If an alternate landing site is not set, the aircraft will hover above the dock, and will start descending only when the battery level is too low.

3. If dock landing detection is not operational (when the dock and the aircraft are disconnected), or the aircraft fails to land on the dock due to bad weather conditions, the aircraft will descend to 5 m (9.8 ft) above the ground and hover. The aircraft will y to the alternate landing site when the battery level is less than 20%. If an alternate landing site is not set, the aircraft will hover above the dock, and will start descending only when the battery level is too low.

• Make sure to set an alternate landing site when conguring the dock. Otherwise, the aircraft may crash-land if the dock is not suitable for landing, damaging the aircraft and the dock.

DJI Dock 2/Matrice 3D Series Unmanned Aircraft Flight Manual

Emergency Procedures

DJI Dock 2/Matrice 3D Series Unmanned Aircraft Flight Manual

4 Emergency Procedures

4.1 General Information

This chapter introduces how to handle the aircraft or control station if one of the following emergencies occur.

4.2 Fire

A prompt will appear in DJI FlightHub 2 and the ight controller will reduce the power of the aircraft when the Intelligent Flight Battery temperature is too high. The battery will be locked for future use if the temperature is too high during ight and cannot be used again after landing.

Follow the instructions below if the Intelligent Flight Battery catches re:

1. If the battery catches re when it is being charged using a charging device, make sure that personal safety is guaranteed, power o the charging device immediately, and disconnect the battery from the charging device. If the battery catches re when the battery is in the aircraft, make sure that personal safety is guaranteed and remove the battery from the aircraft immediately.

2. Move the ammable materials surrounding the battery to a safe distance of more than 5 m .

3. If the re is controllable, use a large amount of sand to cover the location of the

re and pour cold water to cool the battery until there is no smoke coming out. Use re-resistant gloves or other protective tools to avoid direct contact with the battery.

Move the battery to a container with an appropriate amount of salt solution, and then fully immerse the battery in the solution. Leave the container in a cool place for more than 72 hours to fully discharge the battery and take out the battery and dispose it.

4. If the re is uncontrollable, double check that there are no ammable materials surrounding the battery, extend the safety distance to more than 10 m, and evacuate people from the surrounding area. Wait until the battery burns out and the re is extinguished in order to avoid any further accidents.

4.3 Loss of C2 Link

The aircraft will perform the signal lost action if the control signal is lost during ight. Refer to the “Loss of Control Signal” section for more information.

DJI Dock 2/Matrice 3D Series Unmanned Aircraft Flight Manual

4.4 Loss of Navigation Systems

When using xed RTK positioning, the aircraft will switch to GNSS if RTK is unavailable during ight. If GNSS is also unavailable, the aircraft will switch to Attitude (ATTI) mode automatically to stabilize its attitude.

4.5 Control Station Failures

Control station failures include the following situations.

Loss of Control Signal

If the control signal is lost during ight, the aircraft will perform signal lost action. Refer to the “Loss of Control Signal” section for more information.

DJI FlightHub 2 Failure

If DJI FlightHub 2 crashes during automatic operations while the control signal is normal, the C2 link between the aircraft and the control station is still in good condition, so the aircraft will continue performing the current operation until RTH is triggered by low battery level.

Alternate Landing

If the dock is determined unsuitable for landing, alternate landing will be triggered. The aircraft will ascend to the alternate route altitude, then y to the alternate landing site for landing. Open DJI FlightHub 2, Click Devices > Dock and then to check the alternate route altitude.

1. RTH Altitude

2. Alternate Route Altitude

3. Alternate Landing Site

DJI Dock 2/Matrice 3D Series Unmanned Aircraft Flight Manual

• To ensure ight safety, make sure to set an alternate landing site and suitable alternate route altitude when conguring the dock.

Gaining Control Using Remote Controller B

DJI RC Pro Enterprise remote controller can be linked with the aircraft as controller B. During on-site ight tests, the remote controller can take control and manually control ight if any emergency occurs. Follow the steps below to gain aircraft control using the remote controller:

1. Run DJI Pilot 2 and tap Enter Camera View on the homepage. Users will be directed to the camera view by default after nishing the preight check.

2. Tap on the upper left corner to gain the aircraft control and the gimbal control.

• The remote controller should be purchased separately. Pay attention to ight safety when manually controlling with the remote controller.

• DO NOT update the Home Point after gaining control. Otherwise the aircraft cannot return to the dock.

• DO NOT take o using the remote controller if a ight task is initiated from the dock after gaining control with remote controller B. In this case, restart the aircraft before taking o using the remote controller.

Dual Control of the Dock and the Remote Controller

1. The aircraft supports dual control mode, and can be controlled by the dock (controller A) and remote controller B. By default, the dock is given control of both the aircraft and the gimbal camera, while remote controller B is not given any control.

2. When the remote controller has full control, the control sticks are used for controlling the aircraft and the dials for adjusting gimbal movement.

3. When the remote controller has control, it can be used to trigger or cancel RTH, modify aircraft settings, and download or replay media les.

4. The dock will automatically take control of the aircraft before each ight task. A control transfer mechanism will be triggered if either the dock or the remote controller is disconnected from the aircraft. If the remote controller disconnects from the aircraft, control will be transferred to the dock. If the dock disconnects from the aircraft, the remote controller will receive a notication that the user may manually take over aircraft control. If the pilot of the remote controller chooses not to take over aircraft control, the aircraft will automatically perform the signal lost action. If the pilot of the connected remote controller does not choose either option within a specied time, the aircraft will also perform the signal lost action.

DJI Dock 2/Matrice 3D Series Unmanned Aircraft Flight Manual

5. If the disconnected remote controller reconnects with the aircraft during the ight, it will not resume its previous control and will by default have no control of any device.

6. RTH cannot be triggered in DJI FlightHub 2 after remote controller B takes control. The dock will automatically take control of the aircraft if remote controller B is disconnected from the aircraft (such as when the remote controller is powered o or the video transmission signal is lost). The aircraft can continue the ight task in progress.

7. During a ight task, if the remote controller takes control in N mode, the aircraft will continue the ight task. If the ight mode is switched to another mode after taking control, the ight route task will be interrupted and RTH will be triggered. If the remote controller takes control in S mode or F mode, the ight route task will be interrupted and RTH will be triggered.

8. The remote controller can be used to modify the ight control system, the sensing system, other aircraft settings, and the camera settings.

9. Both the rmware of the dock and the aircraft can be updated in DJI FlightHub 2, but the remote controller can only be used to update the rmware of the remote controller.

10. Users can upload the logs of both the dock and the aircraft in DJI FlightHub 2, but can only upload the logs of remote controller using the remote controller.

11. Remote controller B cannot be used to update the Fly Safe database, and cannot upload unlocking license for GEO Zones.

Emergency Stop Button

The dock has one emergency stop button. In an emergency, press the emergency stop button to stop all dock movements when operating or maintaining the dock. The status indicators blink red and yellow alternatively after pressing the emergency stop button.

DJI Dock 2/Matrice 3D Series Unmanned Aircraft Flight Manual

If the aircraft is powered on but the motors are not running, the aircraft cannot take o after pressing the emergency stop button. If the emergency stop button is pressed when the aircraft is performing a ight task, the aircraft will y to the alternate landing site after completing the ight task.

• Pull out or rotate the button clockwise to release the emergency stop button before performing any dock operations (e.g. dock cover control).

Other Failures

When other dock failures occur, such as when the dock has no power supply, no network connection, or when the dock cover cannot be opened, perform troubleshooting.

4.6 Flyaway

When the aircraft is connected to the dock, the coordinates of the aircraft will be uploaded to the cloud and can be viewed in DJI FlightHub 2.

When the aircraft is disconnected from the dock, the last recorded time and coordinates of the aircraft will be displayed in the device status window in DJI FlightHub 2. Users can click the information to center the aircraft location in the middle of the map and then right-click to create a PinPoint to help locate the aircraft during a search. The information will not be displayed after the aircraft re-connects to the dock.
