how would affecting VPS make the drone crash? i still dont get it. I have VPS on flying under 10 meters from the water all the time without any issue/warning.
opening shot of this video i am no more then 4 feet above the water and i routinely fly this low and even lower.
From DJI's manual: - The performance of the Forward and Downward Vision Systems are affected by the surface being flown over. Ultrasonic sensors may not be able to accurately measure distances when operating above sound-absorbing materials and the camera may not function correctly in suboptimal environments. The aircraft will switch from P-mode to Atti mode automatically if neither GPS nor Forward and Downward Vision Systems are available. Operate the aircraft with great caution in the following situations:
Flying over monochrome surfaces (e.g. pure black, pure white, pure red, pure green).
Flying over a highly reflective surfaces.
Flying at high speeds of over 22mph (36kph) at 2 meters or over 11mph (18kph) 1 meter.
Flying over water or transparent surfaces.
Flying over moving surfaces or objects.
Flying over inclined surfaces that will detect sound waves away from the aircraft.
Flying over small objects (e.g. tree branches and power lines).
Flying in an area where the lighting changes frequently or drastically.
Flying over extremely dark (lux < 10) or bright (lux > 100,000) surfaces.
Flying over surfaces that can absorb sound waves (e.g. thick carpet).
Flying over surfaces without clear patterns or texture.
Flying over surfaces with identical repeating patterns or textures (e.g. tiling). |
