Vision Detection for Propellers
After the dock initiates a ight task, the aircraft will perform vision detection for the propellers
before taking o. The following conditions are required for propeller vision detection:
• DJI Matrice 3D Series propellers are used.
• In daytime when the lighting is sucient.
• No vision system warnings in DJI FlightHub 2.
• The aircraft is about to take o before a ight route task.
• The propellers 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 (ADS-B)
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 specic crewed airplanes or
helicopters are approaching and are not able to actively control or take over the DJI aircraft
to avoid collisions. Users should always fly the aircraft within the visual line of sight and be
cautious at all times to ensure ight safety. 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
