systems and be alert when in control of the aircraft. If it is necessary to press
the pause button to cancel RTH, use the live view and fly the aircraft to the
home point manually.
4. Tall buildings may adversely affect the failsafe function. Therefore, it is
important to set an appropriate failsafe altitude before each flight. Adjust the
aircraft altitude while returning home. The RTH altitude is related to the takeoff
point. Make sure the RTH altitude is higher than any obstacle in the operation
area.
5. During RTH, continue to check the live view and the aircraft altitude in case
failsafe is disabled due to the GNSS signal icon having less than three bars.
6. If the battery level is sufficient and the low battery RTH has not been triggered,
the aircraft will return to within 50 m of the last recorded position and attempt
to connect to the remote controller. Consequently, the aircraft may fly to other
points first before returning to the home point. The aircraft will exit RTH if it
reconnects to the remote controller during this period. Otherwise, the aircraft
will rise to the RTH altitude and fly towards the home point.
7. The home point can be updated manually. Make sure to avoid setting the
home point inside or near a building to prevent collisions during RTH or
landing. Note that the RTH altitude is related to the takeoff point.
Low Battery
1. To avoid unnecessary danger, the aircraft will intelligently determine whether
the current battery level is sufficient to return to home based on the current
location. A warning prompt will appear in DJI Pilot 2 when the battery level is
low and the aircraft can only support to return to home.
2. If a battery warning is triggered, promptly return to home or land to avoid
losing control during flight and causing damage to the aircraft, property,
people, or animals. Otherwise, the aircraft will be forced to automatically land
due to the critical low battery. The user is unable to cancel the landing.
Vision System and Infrared Sensing System
1. The vision systems can detect surfaces with clear pattern variations from a
height of up to 30 meters. The vision systems cannot detect surfaces when
the altitude is less than 0.5 meters and the aircraft is flying fast.
2. When the aircraft is flying over water, the vision system or the infrared sensing
system may NOT function properly leading to a false positive, false detection,
or missed detection. Avoid flying over water, DO NOT rely too much on the
vision systems, and operate the aircraft with caution.
3. Obstacle avoidance may be accidentally triggered in some scenarios such as
when the aircraft is flying away from strong, direct sunlight. It is recommended
to disable obstacle avoidance in DJI Pilot 2 and fly the aircraft with caution
to the home point. Make sure to fly higher than all obstacles in the operation
area.
4. Obstacle avoidance and assisted braking will be disabled when operating in
dim lighting or in S-mode or A-mode.
5. Obstacle avoidance cannot detect certain obstacles such as iron wires,
cables, branches, blind spots, and mirrored surfaces. Keep the aircraft within
VLOS and pay close attention to the flight. Use the live view to help operate
the aircraft and manually avoid obstacles in a timely manner.
6. Be alert when in control of the aircraft as the vision systems may be disabled
and the aircraft unable to detect the ground surface in certain scenarios such
as when the lighting of surfaces is extremely dark (<15 lux) or bright (>10,000
lux).
7. The Downward Vision System cannot work properly in the following situations.
Fly with caution.
a. Flying over monochrome surfaces (e.g., pure black, pure white, pure red,
pure green) or without clear texture.
b. Flying over highly reflective surfaces.
c. Flying over water or transparent surfaces.
8
d. Flying over moving surfaces or objects (e.g. above moving people, waving
reeds, shrubs and grass).
e. Flying in an area where the lighting changes frequently or drastically or in an
area where there is excessive exposure to direct and strong lighting.
f. Flying over extremely dark (< 15 lux) or bright (> 10,000 lux) surfaces.
g. Flying at high speeds below 2 meters (over 14m/s at 2 meters or over 5m/s
at 1 meter).
h. Tiny obstacles (e.g. iron wire, cable, tree branch).
i. The lens is dirty (e.g., due to raindrops, fingerprints).
j. Scenes with low visibility (e.g., heavy fog).
8. The infrared sensing systems may NOT provide an accurate distance when in
the following situations:
a. Flying over surfaces that can absorb sound waves (e.g., asphalt road
surfaces).
b. There is a large area of strong reflectors at a distance of more than 15 m
(e.g., multiple traffic signs are placed side by side).
c. Tiny obstacles (e.g. iron wire, cable, tree branch).
d. Mirrored objects (e.g., mirrors) or transparent objects (e.g., water, glass).
e. Scenes with low visibility (e.g., heavy fog).
9. If the aircraft is involved in a collision, it may be necessary to calibrate the
vision systems. Calibrate the vision systems if prompted to do so in the app.
Refer to the user manual for more information.
10. DO NOT fly when it is rainy, foggy, or if visibility is less than 100 m.
11. Keep the cameras of the vision systems and the sensors of the infrared
sensing systems clean at all times.
a. Make sure there are no stickers or any other obstructions over the glass of
the infrared sensing systems and vision systems.
b. Use a soft cloth if there is any dirt, dust, or water on the glass of the
infrared sensing and vision systems. DO NOT use any cleaning products
that contains alcohol.
c. Contact DJI Support if there is any damage to the glass of the infrared
sensing and vision systems.
12. DO NOT hang or place anything in an area that will block the vision systems,
infrared sensing systems, and their observation range.
13. Make sure that the sensor lens is clear and free of stains. DO NOT interfere
with the vision systems and infrared sensing system in any way such as
using a strong light source to illuminate the vision systems or aiming specular
reflectors towards the infrared sensor.
14. If the aircraft attitude angle is larger than 25° or the speed exceeds 17 m/s,
the infrared sensing systems cannot detect obstacles in time for the aircraft to
brake and hover at a safe distance.
15. Be aware of the blind spots (marked grey) of the vision systems and infrared
sensing systems. The infrared sensor observation range is from 0.1 to 10 m.
