Target visibility

As simple example i would remember you that a runway of an international airport is from 1,6 nautical miles (3000 m) and 2,2 nautical miles (4000 m).
If for seeing a contact with for example the sun behind your back you need to barely enter in formation with him we are really unlucky without radar..
About the contact visualization of moving objects it is simpler, cause the human brain (and of the animal in general) is made for enlight the moving objects.
But i need to say that the image that you posted is really interesting because add to the discussion something that we lacked: info about the contact seeing in one of the worst situations, the one with the sun behind the contact.

ok you 'r right. Damn, seems I hve read that chart against the sun

Regarding human brain. Detection of mvmt Ok but tracking no. WHat I mean is that for a positive identification you need to hve your eyeball locked on the moving object and this is more difficult when the speed is increased.

For example, fighter pilots flying fast jet at low alt experience a tunnel vision. It the same phenomena but inversed.

So IMHO it wld be translated that way in the sim: once target in POV, plane image is blurred to the point that we see only that there is "something" there. Then the intensity of the blur decrease progressively to a neat image depending on target range and time on focus (the time the pilot head look in that specific direction)

It's a bit different to what Manu excellently said but I am more focused on the merge case
