The accuracy of the vision position system is likely to be influenced by light intensity and
surface of obstacles, and ultrasonic positioning may be inaccurate if the drone flies close to
sound-absorbing materials. Therefore, be careful not to rely on the vision position system in the
following conditions:

Light intensity: less than 10lux or more than 10,000lux.

Operating temperature: below -10℃ or above 55℃.

Flight altitude: more than 4,000m.

Excessively flight speed.

Pure color surfaces (such as pure black, pure red, pure white and pure green).

Highly reflective surfaces.

Near water or transparent objects.

Surface of moving objects.

Strong or rapid changing light.

Surface with strong ultrasonic absorbing objects.

Surfaces with no clear textures.
 Surface with highly repetitive or patterned textures.

Surface sloped at more than 30 degrees.

Small obstacles (area: less than 1m

).
Smart Flight Function
Pay attention to the following items before enabling the smart flight function:
1. Ensure good light conditions.
2. Ensure that the cameras of the forward and downward vision systems are clean and free of
blemishes.
3. Ensure that the aircraft is fully charged and in standard mode.
4. Ensure that the power-on self-check results of the GDU Mini App comply with the preflight
