Maybe this has already be presented, but just in case, here it is:
My Mavic 2Z has a body roughly 0.25 ft wide. This is the most visible part when flying away or toward the pilot. Now the accepted angular resolution of the human eye is about 1/60 degree or 0.000291 radian.
Calculations:
Distance X Angle (in radians) = Arc length
Distance X 0.000921 = 0.25 ft whence distance = 859 ft or 0.16 mile.
Now even if we up the angular resolution of your eye by a factor of 4, we get about .064 mile straight line.
Note: if the drone is at h=300 ft, the horizontal distance is 804 ft.
I challenge anyone to let someone fly your drone out somewhere randomly to a distance of, say 0.64 mile, while you keep your back turned and then you turn around and see the drone.
Who flies their Mavic 2 drone no farther than 1000 feet? As for myself, I have trouble seeing it four or five hundred feet away.
