• 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.

4. 3D Infrared Sensing System
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 Tripod mode and Obstacle Avoidance Action is set to Avoid
or Brake in DJI Pilot 2. 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 Pilot
2 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.
Extra caution is required when Vision Positioning and Obstacle Sensing are
disabled.
• Disabling Vision Positioning and Obstacle Sensing takes eect only when ying
manually, and will not take eect when using auto modes such as RTH, or auto
landing.
