information about the Aircraft Status Indicator: 

Aircraft

Flight Controller 

The Inspire 1’s fight controller is based on DJI fight controller with several enhancements such as new 

fight mode and new safe mode. Three safe modes are available: Failsafe, Return Home and Dynamic 

Home Point. These features ensure the safe return of your aircraft if the control signal is lost. A fight 

recorder stores crucial fight data for each fight. 

Flight Mode

Three fight modes are available. The details of each fight mode are found in the section below: 

P mode (Positioning) : P mode works best when GPS signal is strong. There are three different states of P 

mode, which will be automatically selected by the Inspire 1 depending on GPS signal strength and Vision 

Positioning sensors:

P-GPS: GPS and Vision Positioning both are available, and the aircraft is using GPS for positioning. 

P-OPTI: Vision Positioning is available but the GPS signal is not. Aircraft is using only Vision 

Positioning for hovering 

P-ATTI: Neither GPS or Vision Positioning available, aircraft is using only its barometer for positioning, 

so only altitude is controlled. 

A mode (Attitude): The GPS and Vision Positioning System is not used for holding position. The aircraft 

only uses its barometer to maintain altitude. If it is still receiving a GPS signal, the aircraft can automatically 

return home if the Remote Controller signal is lost and if the Home Point has been recorded successfully. 

F mode (Function): Intelligent Orientation Control (IOC) is activated in this mode. For more information 

about IOC, refer to the IOC in Appendix.

Use the Flight Controller mode switch to change the fight mode of the aircraft, refer to the “Flight 

Mode Switch” on P27 for more information.

Return to Home (RTH)

The Return to Home (RTH) brings the aircraft back to the last recorded Home Point. There are three cases 

that will trigger RTH procedure; they are Smart RTH, Low Battery RTH and Failsafe RTH.

GPS Description

Home Point

The Home Point is the location at which your aircraft takes off when the 

GPS signal is strong. You can view the GPS signal strength through 

the GPS icon ( ). If you are using the Dynamic Home Point 

setting, the Home Point will be updated to your current position as you 

move around and when the Aircraft Status Indicator blinks green. 

Smart RTH

Using the RTH button on the remote controller (refer to “RTH button” on P28 for more information) or the 

RTH button in the DJI GO app when GPS is available to enables smart RTH. The aircraft return to the 

latest recorded Home Point, you may control the aircraft's orientation to avoid collision during the Smart 

RTH. Press the Smart RTH button once to start the process, press the Smart RTH button again to exit 

Smart RTH and regain the control.

Aircraft automatically descends and lands if RTH is triggered when the aircraft fies within a 20 

meter (65 feet) radius of the Home Point.

Aircraft cannot avoid obstruction during the Failsafe RTH, therefore it is important to set an 

reasonable Failsafe altitude before each fight. Launch the DJI GO app and enter “Camera” 

view and select “MODE” to set the Failsafe altitude. 

Aircraft will stop ascending and immediately return to the Home Point if you move the throttle 

stick if the aircraft reaches 20 m altitudes or beyond during Failsafe. 

 When the critical battery level warning activates and the aircraft is descending to land 

automatically, you may push the throttle upward to hover the aircraft and navigate it to a more 

appropriate location for landing.

 Color zones and markers on the battery level indicator refect estimated remaining fight time 

and are adjusted automatically, according to the aircraft’s current status.

Failsafe RTH

Failsafe RTH is activated automatically if remote controller signal (including video relay signal) is lost for 

more than 3 seconds provided that Home Point has been successfully recorded and compass is working 

normally. Return home process may be interrupted and the operator can regain control over the aircraft if 

a remote controller signal is resumed.

2. Tap“ ”and select“ ”, to reset the remote controller’s coordinates as the new Home Point.

3. Tap“ ”and select“ ”, to reset the aircraft’s coordinates as the new Home Point.

4. The aircraft status indicator blinks green to show Home Point is set successfully.

Vision Positioning System

DJI Vision Positioning is a positioning system that uses ultrasonic and image data to help the aircraft 

identify its current position. With the help of Vision Positioning, your Inspire 1 can hover in place more 

precisely and fly indoors or in other environments where there is no GPS signal available. The main 

components of DJI Vision Positioning are located on the bottom of your Inspire 1, including [1]two sonar 

sensors and[2]one monocular camera. 

Using Vision Positioning 

Vision Positioning is activated automatically when the Inspire 1 is powered on. No manual action is 

required. Vision Positioning is typically used in the indoor environment where no GPS is available. By 

using the sensors on the Vision Positioning system, Inspire 1 can perform precision hovering even when 

no GPS is available.

INSPIRE 1 User Manual

Follow the steps below to use Vision Positioning:

1. Toggle the switch to “P” as shown the fgure to the right:

2. Place the Inspire 1 on a fat surface. Notice that the Vision Positioning system 

cannot work properly on surfaces without pattern variations. 

3. Power on the Inspire 1. The aircraft status indicator will fash twice in green light, 

which indicates the Vision Positioning system is ready. Gently push the throttle up 

to lift off, and the Inspire 1 will hover in place.

The performance of your Inspire 1’s Vision Positioning System is subject to the surface you are 

fying over. The ultrasonic waves may not be able to accurately measure the distance over sound 

absorbing materials, and the camera may not function correctly in suboptimal environments. The 

aircraft will switch from “P” mode to “A” mode automatically if both GPS and Vision Positioning 

System are not available. So operate the aircraft cautiously when in any of the following situations: 

Flying over monochrome surfaces (e.g. pure black, pure white, pure red, pure green).

Flying over a highly refective surfaces. 

Flying at high speeds(over 8m/s at 2 meters or over 4m/s at 1 meter).

Flying over water or transparent surfaces.

Flying over moving surfaces or objects.

Flying in an area where the lighting changes frequently or drastically. 

Flying over extremely dark (lux < 10) or bright (lux > 10,000) surfaces. 

Flying over surfaces that can absorb sound waves (e.g. thick carpet). 

Flying over surfaces without clear patterns or texture. 

Flying over surfaces with identical repeating patterns or textures (e.g. tiles with same design). 

Flying over inclined surfaces that will defect sound waves away from the aircraft.

In the event of loss of remote controller’s signal, the aircraft will hover for 8 seconds and then 

auto-land if it is in “P” mode. 

Keep the sensors clean at all times. Dirt or other debris may adversely affect the effectiveness 

of the sensors.

The effective hovering altitudes of the aircraft is from 0 to 2.5 meters. 

Vision Positioning system may not function properly when the aircraft is fying over water.

Vision Positioning system may not be able to recognize pattern on the ground in low light 

conditions (less than 100lux).

Do not use other ultrasonic devices with frequency of 40 KHz when Vision Positioning system is 

in operation. 

Vision Positioning system may not be able to stabilize the aircraft when flying close to the 

ground (below 0.5 meters) in fast speed.

Keep the animals away from the aircraft when Vision Positioning system is activated. The sonar 

sensor emits high frequency sound that is only audible to some animals.

Flight Recorder 

Flight data is automatically stored in the internal storage device of the aircraft. User can gain access to 

these data through the DJI GO app. This includes fight duration, orientation, distance, aircraft status 

information, speed, and other parameters. 

Attaching and Detaching the Propellers 

Use only DJI approved propellers with your Inspire 1. The grey or black nut on the propeller indicates 

the rotation direction of the propeller and where it should be attached. To attach the propellers properly,

Low Temperature Notice:

1. The performance of the intelligent Flight Battery is significantly reduced when flying in a low 

temperature environments (those with air temperatures below 5°C). Ensure that the battery is fully 

charged and the cell voltage is at 4.35 V before each fight. 

2. Using the Intelligent Flight Battery in extremely low temperature environments (those with air 

temperatures below -10°C) is not recommended. When flying in environments with temperatures 

between 5°C and -10°C, the Intelligent Flight Battery should be able to achieve the appropriate voltage 

levels (above 4.2 V), but it is recommended that you apply the included insulation sticker to the battery 

in order to prevent a rapid drop in temperatures. 

3. If the DJI GO app displays the “Critical Low Battery Level Warning” when fying in low temperature 

environments, stop fying and land the aircraft immediately. You will still be able to control the aircraft’s 

movement when this warning is triggered. 

4. Store the Intelligent Flight Battery in a room temperature environment and ensure that its temperature 

exceeds 5°C before using it in the low temperature environment.

5. When using the Inspire 1 in a low temperature environment, begin by allowing the aircraft to hover at a 

low altitude, for approximately one minute, to heat the battery. 

6. To ensure optimum performance, keep the Intelligent Flight Battery’s core temperature above 20°C 

when in use.

In cold environments, insert the battery into the battery compartment and allow the aircraft to 

warm up for approximately 1-2 minutes before taking off.
