• When pushing the control sticks to exit the operation, the aircraft requires a braking
distance. Make sure that there is a safe distance between the aircraft and any
obstacles.
2. Avoiding an Obstacle
After switching to Manual operation mode, users can control the aircraft to avoid the
obstacle from Point C to D.
3. Resuming Operation
Select one of the three return points marked as E1, E2, or E3. Tap Resume and the aircraft
flies from the point marked D to the selected return point following a perpendicular line.
• The amount of selectable return points is related to the position of the aircraft. For
example, there is no E2 (points on non-spraying route) for Route operation mode.
Select according to the app display.
• Make sure that the aircraft has completely avoided the obstacle before resuming
operation.
• In the event of an emergency, make sure that the aircraft is operating normally and
fly the aircraft manually to a safe area to resume operation.
• Repeat the instructions above to exit and resume operation in the event of an
emergency when returning to the route, such as whenever obstacle avoidance is
required.
System Data Protection
In Route, or Fruit Tree operation mode, the System Data Protection feature enables the aircraft
to retain vital system data such as operation progress and breakpoints after the aircraft is
powered off to replace a battery or refill the spray tank. Follow the instructions in Operation
Resumption to resume the operation after restarting the aircraft.
During Route operations, in situations such as when the app crashes or the remote controller
disconnects from the aircraft, the breakpoint will be recorded by the flight controller and
recovered automatically in the app once the aircraft is reconnected. If recovery is not performed
automatically, users can perform the operation manually. Go to Aircraft Settings in the app and
tap Restore Unfinished Task. Recall the operation in the Executing tag in the operation list.
Empty Tank Warning
Prole
The aircraft calculates the empty tank and refill points according to the preset remaining liquid
level threshold, current remaining liquid level, aircraft status, and operation parameters and
displays the empty tank point on the map. In Route, Manual, and Fruit Tree operations, users
can set the action the aircraft will perform for empty tank point.
