dji AIR 3S - Sensing System

◆
During takeo, the aircraft must vertically ascend at least 7m before moving
horizontally.
◆
The Home Point terrain features must remain largely unchanged.
◆
The terrain features of the Home Point must be suciently distinctive.
Terrain such as a snow-covered eld is not suitable.
◆
The lighting conditions must not be too bright or too dark.
• During landing, movement of any other control stick apart from the throttle stick
will be regarded as giving up precision landing, and the aircraft will descend
vertically.

The omnidirectional vision system works best with adequate lighting and clearly marked
or textured obstacles. The omnidirectional vision system will activate automatically when
the aircraft is in Normal or Cine mode and Obstacle Avoidance Action is set to Bypass or
Brake in DJI Fly. The positioning function is applicable when GNSS signals are unavailable
or weak.
The auxiliary light located at the bottom of the aircraft can assist the downward vision
system. It will automatically turn on by default in low-light environments when the ight
altitude is under 5 m after takeo. You can also turn it on or o manually in the DJI Fly
app. Each time the aircraft is restarted, the auxiliary light will revert back to the default
setting Auto.
• When Vision Positioning and Obstacle Sensing are disabled, the aircraft relies
only on GNSS to hover, omnidirectional obstacle sensing is unavailable, and the
aircraft will not automatically decelerate during descent close to the ground.
