A manned aircraft also needs to avoid everything including balloons, gliders, GA etc.
How much of the radars to detect weather and traffic have to be carried and operated aboard every craft, and how far can aircraft rely on having (heavier, better-powered) radars on ground watching for weather and traffic and transmitting information when required?
