itself. Operate the aircraft with great caution in the
following situations, which may cause the aircraft
to enter Attitude mode:
a. Flying at high speed below 2 ft (0.5 m).
b. Flying over monochrome surfaces (e.g. pure
black, pure white, pure red, pure green).
c. Flying over highly reflective 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 fine objects (e.g. tree
branches or power lines).
k. Flying at speeds of over 11 mph (18 kph)
at 3.5 ft (1 m) or lower.
4. If the aircraft's Vision Positioning system fails for
3 seconds when its flying altitude is above 20 ft
(6 m), Failsafe Protection will automatically initiate
landing. If the Vision Positioning system recovers
during landing, Failsafe Protection will shut off and
the aircraft will hover.
5. The Vision Positioning System may not be able
to recognize patterns on the ground in very
dark (< 100 lux) environments. DO NOT take off
if there is a warning prompt in the Tello app telling
you that the environment is too dark.
