Emergency Procedures
General Information
This chapter introduces how to handle the aircraft or control station if one of the following
emergencies occur.
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.
Loss of C2 Link
The aircraft will perform the signal lost action if the control signal is lost during ight. Refer to
the RTH > Advanced RTH > Trigger Method, and then the Loss of Control Signal section for more
information.
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.
