OBSTACLE AVOIDANCE PILOTING MODE
The Obstacle Avoidance Piloting Mode (OAPM) operates differently when the
drone is piloted directly (through the controller), and when the drone carries
out an automated or assisted flight (Flight Plan and Vehicle Mission, for
example). In direct piloting, the OAPM stops the drone soon enough to avoid
collision with the environment. During automated or assisted flights, the OAPM
navigates the drone between obstacles, which can lead to trajectories different
of those expected.
The OAPM can be totally impaired by: low ambient light; a defective gimbal;
a damaged or defective stereo camera; the consequences of an impact on the
stereo camera
–
which may require a recalibration.
BEFORE FLYING
Check the stereo camera is perfectly clean and free. Dust and other residues on
its lenses may affect its performance. If the lenses require cleaning, wipe it with
a soft cloth. Never use detergent or alcohol to clean ANAFI Ai.
FLYING CONDITIONS
The performance of the OAPM can be affected by: lighting, nature of
obstacle surface, direction and speed of the drone, presence of water on the
stereo camera lenses (in case of rain for example).
Be especially careful when using the drone in the following conditions, as the
OAPM might not work optimally.
• In front of surfaces or objects that are:
- monochrome (plain white or black, or any other color, without distinct
texture or motive);
- reflective;
- water or transparent;
- mobile;
- very dark or very bright.
• In
areas where the lighting conditions change drastically or very rapidly.
• In
rainy conditions.
Obstacles might not be avoided when the speed of the drone exceeds 10 m/s.
- DO NOT FLY in the fog or in poor visibility conditions.
- DO NOT OBSTRUCT the camera.
- DO NOT FLY the drone toward people, animals, small or thin objects (as
tree branches or power lines) or transparent materials (glass, water).
- REMAIN ALERT DURING ALL FLIGHTS: keep the control of the drone at all
times.
- DO NOT RELY ON THE OAPM.
Flight assistance and safety functions as the OAPM are designed to help the pilot,
not to replace his control over the drone. Do not lose sight of the drone and
always remain focused on its flight. Rely on your own judgement to control the
drone and manually avoid obstacles. Be wary of obstacles, in particular people
and animals which may find themselves on the trajectory of the drone. It is
important to set an RTH altitude before each flight.
If the drone suffers an impact, a recalibration of its stereo camera may be
required. Follow in app FreeFlight 7 instructions to carry out this recalibration.
As illustrated by the following figure, Parrot asks ANAFI Ai pilots to be especially
careful when they back up their drone, as the OAPM has an approximately 55°
blind zone (or dead angle), behind the drone, toward the ground.
