line of sight

I'm inclined like everybody else to consider perception on a line-of-sight basis instead of on a sort of all-around grasp.

As needed, line and non-line-of-sight weapons of near pin-point accuracy would be delivered across the entire area of operation.

Radio contact is strictly line-of-sight inside a hunk of metal.

There were other instruments in other line-of-sight positions, very far away.

He started the fuel pumps winding up, and swung the ship to point normal to the line-of-sight to the jammer.
