C31 Field Entry, Exit, and Return Flight Logic
The C31 drone allows operators to configure both the field entry/exit speed and altitude
independently from the spraying altitude. This provides better efficiency when entering and
exiting the field.
1. Field Entry Flight Logic
When the configured entry/exit altitude and speed are different from the terrain-following
spraying altitude, the drone will fly using the configured entry/exit altitude and speed during
transit.
Entry Flight Path
During the spraying operation, the drone will switch to the configured terrain-following spraying
height.
2. Return Flight Logic
When the drone finishes spraying or the tank becomes empty, the drone will:
- Climb to the configured entry/exit altitude
- Return to the takeoff point at the configured entry/exit altitude and speed
- This behavior is the same whether a Safety Point (transfer point) is configured or not.
Return Flight Path

3. Advantages of This Logic
This flight logic improves operational efficiency when entering or exiting the field, especially when:
- the takeoff location contains low obstacles
the operator wants to transit quickly to the working area
large fields require long transit distances
4. Important Safety Notice (Power Lines)
If power lines exist within the field, operators must ensure:
- The configured entry/exit altitude is lower than the height of the power lines
- The upward radar is enabled
- The operator visually confirms that the drone can safely pass under overhead lines Failure to properly configure altitude may lead to collision with overhead power lines.
5. Upcoming Logic Improvement
The R&D team is developing an optional flight logic selection that will allow operators to
choose how the drone behaves between the Safety Point and the Breakpoint.
The operator will be able to select:
This improvement will allow operators to optimize flight safety and efficiency based on field
conditions.
