User Manual
Using the Forward and Backward Vision Systems, the aircraft is able to actively brake when obstacles
are detected in front. The Forward and Backward Vision Systems work best when lighting is adequate
and obstacles are clearly marked or textured. The aircraft must y at no more than 17.9 mph (22.8 kph)
to allow for sucient braking distance.
Using the Vision Systems
The Downward Vision System is activated automatically when the aircraft is turned on. No further action
is required. Using the Downward Vision System, the aircraft can hover precisely even without GPS.
The Downward Vision System is typically used in indoor environments where GPS is unavailable. The
Downward Vision System works best when the aircraft is at altitudes of 1.6 to 26 ft (0.5 to 8 m). If
the aircraft’s altitude is above 8 m the Vision Positioning function may be aected, so extra caution is
required.
Follow the steps below to use the Downward Vision System:
1. Ensure the aircraft is in P-mode and place the aircraft on a at surface. Note that the Downward
Vision System cannot work properly on surfaces without clear pattern variations.
2. Turn on the aircraft. The aircraft will hover in place after takeo. The Aircraft Status Indicator will ash
green twice, which indicates the Downward Vision System is working.
The performance of the Vision Systems is affected by the surface being flown over. The
aircraft automatically changes from to ATTI mode when the Vision Systems are unavailable
or disabled and either the GPS signal is weak or the compass is experiencing interference.
Operate the aircraft with great caution in the following situations:
a. Flying at high speeds below 1.6 ft (0.5 m).
b. Flying over monochrome surfaces (e.g. pure black, pure white, pure red, pure green).
c. Flying over highly reective surfaces.
d. Flying over water or transparent surfaces.
e. Flying over moving surfaces or objects.
f. Flying in an area where the lighting changes frequently or drastically.
g. Flying over extremely dark (< 10 lux) or bright (> 100,000 lux) surfaces or towards bright
sources of light (e.g. towards sunlight).
h. Flying over surfaces without clear patterns or texture.
i. Flying over surfaces with identical repeating patterns or textures (e.g. tiling).
j. Flying over small and ne objects (e.g. tree branches or power lines).
k. Flying at high speeds of over 11.2 mph (18 kph) at 3.3 ft (1 m).
