Return-to-Home (RTH)
Return-to-Home (RTH) function brings the aircraft back to the last recorded Home Point. There are three types of RTH: Smart RTH, Low Battery RTH, and Failsafe RTH. This section describes these three scenarios in detail.

	GPS	Description
Home Point		If a strong GPS signal was acquired before takeoff, the Home Point is the location from which the aircraft launched. The GPS signal strength is indicated by the GPS icon ( Less than 4 bars is considered a weak GPS signal). The aircraft status indicator will blink rapidly when the home point is recorded.

• The aircraft can sense and avoid obstacles when the Forward Vision System is enabled and lighting conditions are sufficient. The aircraft will automatically climb up to avoid obstacles and descend slowly as it returns to the home point. To ensure the aircraft returns home forwards, it cannot rotate or fly left and right during RTH while the Forward Vision System is enabled.

Failsafe RTH
The Forward Vision System allows the aircraft to create a real-time map of its flight route as it flies. If the Home Point was successfully recorded and the compass is functioning normally, Failsafe RTH will be automatically activated if the remote controller signal is lost for more than three seconds. The aircraft will plan its return route and retrace its original flight route home. The aircraft will hover for 10 seconds at its current location. When it regains signal connection it will wait for pilot commands. The Return-toHome process may be interrupted and the pilot given control of the aircraft if the remote controller signal connection is re-established.

Failsafe Illustration

• Aircraft cannot return to the Home Point when GPS signal is weak or unavailable.
• Aircraft automatically descends and lands if RTH is triggered when the aircraft flies within a 65 feet (20 meters) radius of the Home Point. Aircraft will stop ascending and immediately return to the Home Point if you move the left stick if the aircraft reaches 65 feet (20 meters) altitudes or beyond during Failsafe.
• The aircraft cannot avoid obstruction during Failsafe RTH if Forward Vision System is disabled. It is important to set a suitable Failsafe altitude before each flight. Launch the DJI GO 4 app, enter "Camera" and tap to set the Failsafe Altitude.
• User cannot control the aircraft while the aircraft is ascending to 65 feet (20 meters) from the current altitude. However, user can press RTH button once to exit ascending and regain control.

Smart RTH
Use the RTH button on the remote controller or tap the RTH button in the DJI GO 4 app and follow the onscreen instructions when GPS is available to initiate Smart RTH. The aircraft will then automatically return to the last recorded Home Point. Use the remote controller to control the aircraft's speed or altitude to avoid a collision during the Smart RTH process. As the aircraft returns, it will use the primary camera to identify obstacles as far as 300m in front, allowing it to plan a safe route home. Press and hold the Smart RTH button once to start the process, and press the Smart RTH button again to terminate the procedure and regain full control of the aircraft.

Low Battery RTH
The low battery level failsafe is triggered when the DJI Intelligent Flight Battery is depleted to a point that may affect the safe return of the aircraft. Users are advised to return home or land the aircraft immediately when prompted. The DJI GO 4 app will display a notice when a low battery warning is triggered. The aircraft will automatically return to the Home Point if no action is taken after a ten-second countdown. The user can cancel the RTH procedure by pressing the RTH button on the remote controller. The thresholds for these warnings are automatically determined based on the aircraft's current altitude and distance from the Home Point.
The aircraft will land automatically if the current battery level can only support the aircraft long enough to descend from its current altitude. The user can still use the remote controller to alter the aircraft's orientation during the landing process.
The Battery Level Indicator is displayed in the DJI GO 4 app, and is described below:

Battery Level Warning	Remark	Aircraft Status Indicator	DJI GO 4 App	Flight Instructions
Low battery level warning	Battery power is low. Land the aircraft.	Aircraft status indicator blinks RED slowly.	Tap "Go-home" to have the aircraft return to the Home point and land automatically, or "Cancel" to resume normal flight. If no action is taken, the aircraft will automatically go home and land after 10 seconds. Remote controller will sound an alarm.	Fly the aircraft back and land it as soon as possible, then stop the motors and replace the battery.
Critical Low battery level warning	The aircraft must land immediately.	Aircraft status indicator blinks RED quickly.	The DJI GO 4 app display will flash red and the aircraft will start to descend. The remote controller will sound an alarm.	Allow the aircraft to descend and land automatically.
Estimated remaining flight time	Estimated remaining flight based on current battery level.	N/A	N/A	N/A

• When the Critical low battery level warning is triggered and the aircraft begins to land automatically, push the left stick upward to make the aircraft hover at its current altitude, giving you an opportunity to navigate to a more appropriate landing location.
• The colored zones and markers on the battery level indicator bar reflect the estimated remaining flight time. They are automatically adjusted according to the aircraft's current location and status.

Precision Landing
The Phantom 4 Advanced / Advanced+ automatically scans and attempts to match the terrain features underneath during Return to Home. When current terrain matches home point terrain, the Phantom 4 Advanced / Advanced+ will start landing immediately to achieve precision landing. The DJI GO 4 app will show a terrain feature mismatch prompt if matching fails.

• Precision Landing performance is subject to the following conditions:

1. Home point is recorded upon take off, and cannot not be refreshed during flight.
2. Aircraft must take off vertically. Take off altitude must be greater than 7 meters.
3. Home point terrain features remain largely unchanged.
4. Home point terrain with no distinctive features will affect the performance.
5. Lighting conditions cannot be too light nor too dark.

• The following actions are available during landing:

1. Pull throttle down to accelerate landing.
2. Moving the control sticks in any other direction will stop Precision Landing. The Phantom 4 Advanced / Advanced+ will descend vertically and Landing Protection will remain active.

Failsafe Safety Notices

	The aircraft cannot avoid obstruction during the Failsafe RTH when the Forward Vision System is disabled. Therefore, it is important to set a suitable Failsafe altitude before each flight. Launch the DJI GO 4 app, enter "Camera" and tap to set the Failsafe Altitude.
	If the aircraft is flying under 65 feet (20 meters) and Failsafe (including Smart RTH, Lower Battery RTH ) is triggered, the aircraft will first automatically ascend to 65 feet (20 meters) from the current altitude. You can only cancel the ascending by exiting the Failsafe.
	Aircraft automatically descends and lands if RTH is triggered when the aircraft flies within a 65 feet (20 meters) radius of the Home Point. Aircraft will stop ascending and immediately return to the Home Point if you move the left stick if the aircraft reaches 65 feet (20 meters) altitudes or beyond during Failsafe.
	Aircraft cannot return to the Home Point when GPS signal is weak or unavailable.
	If you move the left stick after the aircraft rises above 65 feet (20 meters) but below the pre-set Failsafe RTH altitude, the aircraft will stop ascending and immediately return to the Home Point.

Obstacle Avoidance During RTH
Aircraft can now sense and actively attempt to avoid obstacles during RTH, provided that the lighting conditions are adequate for the Forward Vision System. Upon detecting an obstacle, the aircraft will act as follows:

1. The aircraft will use the primary camera to identify obstacles as far as 984 feet (300 meters) in front, allowing it to plan a safe route home.
2. The aircraft decelerates when an obstacle is sensed at 49 feet (15 meters) ahead.
3. The aircraft stops and hover then start ascending vertically to avoid the obstacle. Eventually, the aircraft will stop climbing when it is at least 16 feet (5 meters) above the detected obstacle.
4. Failsafe RTH procedure resume, the aircraft will continue flying to the Home Point at the current altitude.

• The Obstacle Sensing function is disabled during RTH descent. Proceed with care.
• To ensure the aircraft returns home forwards, it cannot rotate during RTH while the Forward Vision System is enabled.
• The aircraft cannot avoid obstacles above, beside, or behind the aircraft.

Landing Protection Function
Landing Protection will activate during auto landing.

1. Landing Protection determines whether the ground is suitable for landing. If so, the Phantom 4 Advanced / Advanced+ will land gently.
2. If Landing Protection determines that the ground is not suitable for landing, the Phantom 4 Advanced / Advanced+ will hover and wait for pilot confirmation. The aircraft will hover if it detects the ground is not appropriate for landing even with a critically low battery warning. Only when the battery level decreases to 0% will the aircraft land. Users retain control of aircraft flight orientation.
3. If Landing Protection is inactive, the DJI GO 4 app will display a landing prompt when the Phantom 4 Advanced / Advanced+ descends below 0.3 meters. Tap to confirm or pull down the control stick for 2 seconds to land when the environment is appropriate for landing.

• Landing Protection will not be active in the following circumstances:
  1. When the user is controlling the pitch/roll/throttle sticks (Landing ground detection will re-activate when control sticks are not in use)
  2. When the positioning system is not fully functional (e.g. drift position error)
  3. When the downward vision system needs re-calibration
  4. When light conditions are not sufficient for the downward vision system
• If an obstacle is within 1-meter of the aircraft, the aircraft will descend to 0.3m above the ground and hover. The aircraft will land upon with user confirmation.

Intelligent Flight Mode
TapFly
Introduction
With the TapFly feature, users can now tap on the mobile device screen to fly in the designated direction without using the remote controller. The aircraft will automatically avoid obstacles it sees or brake and hover provided that the lighting is appropriate (< 300 lux) nor too bright (> 10,000 lux).

Gesture Mode
In Gesture Mode, the Phantom 4 Advanced / Advanced+'s Vision System recognizes gestures, allowing it to follow and capture selfies without a phone or a controller. Follow the steps below to use Gesture Mode:

Modes	Prompts	Front LEDs	Remarks
Confirm the subject		Slow Red Flashing	Ensure the forward vision system is active and there is enough light. Tap the icon and move in front of the camera for the Phantom 4 Advanced / Advanced+ to recognize you.
Confirm the distance		Red Flashes Twice	Raise your arms and wave to the Phantom 4 Advanced / Advanced+, the Front LEDs will blink red twice once it confirms the shooting distance.
Selfie Count Down		Fast Red Flashing	Put your fingers in front on your face as shown.

• Gesture Mode can only be used in Photo Mode.
• Fly the aircraft 2 meters or higher above the ground then move in front of the camera to be recognized. Front LED Indicators will blink red rapidly if the Phantom 4 Advanced / Advanced+ fails to recognize a subject.
• Enabling GPS on your phone will allow the Phantom 4 Advanced / Advanced+ to follow with more accuracy while flying in Gesture Mode.

Tripod Mode
Tap the icon in the DJI GO 4 app to enable Tripod Mode. In Tripod Mode, the maximum flight speed is limited to 5.6 mph (9 kph) and the braking distance is reduced to 6.6 ft (2 m). Responsiveness to stick movements is also reduced for smoother more controlled movements.

• Only use Tripod Mode where the GPS signal is strong or light conditions are ideal for the vision system. If GPS signal is lost and the vision system cannot function, it will automatically switch to Atti mode. In this case, flight speed will increase and the aircraft cannot hover in place. Use Tripod Mode carefully.

Terrain Follow Mode
The Downward Vision System is utilized in Terrain Follow Mode to maintain a height above ground between 1 and 10 meters. This mode is designed for use on grassland sloped at no more than 20°. Enable the Terrain Follow Mode by tapping the Intelligent Flight Mode icon in the DJI GO 4 app. When this mode is enabled, the aircraft's current height will be recorded. The aircraft will maintain the recorded height during flight and ascend when the slope rises. However, the aircraft will not descend in downward slopes.

• It is important that you only fly in conditions where the Vision Position System can function correctly; otherwise the Terrain Follow Mode will not work.

Vision System
The main components of the Vision System are located on the front and bottom of the Phantom 4 Advanced / Advanced+, including [1] [2] two stereo vision sensors and [3] two ultrasonic sensors. The Vision System uses ultrasound and image data to help the aircraft maintain its current position, enabling precision hovering indoors or in environments where a GPS signal is not available. The Vision System constantly scans for obstacles, allowing the Phantom 4 Advanced / Advanced+ to avoid them by going over, around, or hovering.

Detection Range
The detection range of the Vision System is depicted as follow. Note that the aircraft cannot sense and avoid the obstacles that are not within the detection range.

Calibrating Sensors
Vision Systems cameras installed on the aircraft are calibrated on delivery. However these cameras are vulnerable to excessive impact and will require occasional calibration via DJI ASSISTANT^TM 2 or the DJI GO 4 app. Follow the steps below to calibrate the camera.

Quick Calibration
Use quick calibration when the DJI GO 4 app notify that vision sensor calibration is required. Tap through "Aircraft Status" -> "Vision Sensors" to start quick calibration.

• Quick calibration is quick fix to vision sensor issues. Connecting the aircraft to a computer to carry out a full calibration using DJI Assistant 2 is recommended when possible. Only calibrate when lighting conditions are adequate and on textured surfaces i.e. grass.
• Do not calibrate the aircraft on highly reflective surfaces such as Marble or ceramics.

Using Vision Positioning
Vision Positioning is activated automatically when the aircraft is turned on. No further action is required. Vision Positioning is typically used in indoor environments, where GPS is unavailable. Using the sensors that are built into the Vision System, the aircraft can hover precisely even without GPS.

Follow the steps below to use Vision Positioning:

1. Toggle the flight mode switch to P-mode.
2. Place the aircraft on a flat surface. Note that the Vision System cannot work properly on surfaces without clear pattern variations.
3. Turn on the aircraft. The aircraft status indicator will flash green two times, which indicates the Vision Positioning is ready. Gently push the left stick up to lift off and the aircraft will hover in place.

Assisted Braking from Obstacle Sensing
Powered by the Obstacle Sensing, the aircraft will now be able to actively brake when obstacles are detected around the aircraft. Note that Obstacle Sensing function works best when lighting is adequate and the obstacle is clearly marked or textured. The aircraft must fly at no more than 31mph (50kph) to allow sufficient braking distance.

• The performance of your Vision System is affected by the surface being flown over. Ultrasonic sensors may not be able to accurately measure distances when operating above soundabsorbing materials and the camera may not function correctly in suboptimal environments. The aircraft will switch from P-mode to A-mode automatically if neither GPS nor Vision System are available. Operate the aircraft with great caution in the following situations:

1. Flying over monochrome surfaces (e.g. pure black, pure white, pure red, pure green).
2. Flying over a highly reflective surfaces.
3. Flying at high speeds of over 31mph (50kph) at 2 meters or over 11mph (18kph) at 1 meter.
4. Flying over water or transparent surfaces.
5. Flying over moving surfaces or objects.
6. Flying in an area where the lighting changes frequently or drastically.
7. Flying over extremely dark (lux < 10) or bright (lux > 100,000) surfaces.
8. Flying over surfaces that can absorb sound waves (e.g. thick carpet).
9. Flying over surfaces without clear patterns or texture.
10. Flying over surfaces with identical repeating patterns or textures (e.g. tiling).
11. Flying over inclined surfaces that will deflect sound waves away from the aircraft.

• Keep sensors clean at all times. Dirt or other debris may adversely affect their effectiveness.
• Vision Positioning is only effective when the aircraft is at altitudes of 0.3 to 10 meters.
• The Vision Positioning may not function properly when the aircraft is flying over water.
• The Vision System may not be able to recognize pattern on the ground in low light conditions (less than 100 lux).
• Do not use other ultrasonic devices with frequency of 40 KHz when Vision System is in operation.

• Keep animals away from the aircraft when Vision Positioning is activated. The sonar sensor emits high frequency sounds that are audible to some animals.

Flight Recorder
Flight data is automatically recorded to the internal storage of the aircraft. This includes flight telemetry, aircraft status information, and other parameters. To access this data, connect the aircraft to the PC through the Micro USB port and launch the DJI 2.

Attaching and Detaching the Propellers
Use only DJI approved propellers with your Phantom 4 Advanced / Advanced+. The grey and black ring on the propeller indicate where they should be attached and in which direction whey should spin.
