radar separation

radar separation

The separation used when aircraft position information is derived from radar sources (ICAO). The traffic is spaced out in accordance with the established minimums. The separation minimums are basically 5 NM and, at the discretion of the authority, when within 40 NM of the radar and below flight level 245, 3 NM; both these assume that primary and secondary radars are available. If only the secondary is available, then the radar separation is 8 NM.

That takes longer than the more sophisticated radar separation used in Singapore and elsewhere in the world, which allows a controller to more quickly take stock of radar returns from all aircraft in the area.
The Juneau WAM system uses multilateration to provide controllers at the Anchorage Air Route Traffic Control Center with high accuracy, high availability surveillance of aircraft and helicopters, enabling ATC-provided radar separation and traffic advisory services to pilots operating in the Juneau airspace.
When I say "change to advisory frequency", that's the same as saying, "radar service terminated." We just leapt from radar separation to IFR non-radar separation standards.
Radar separation rules still apply: three miles horizontally, 1000 feet vertically, or at least 15 degrees of divergence.
The Controller's Handbook 9-3-2b requires controllers to provide radar separation of three miles (six miles above FL 600) from special use airspace.
Radar separation between IFR airplanes requires 1000 feet vertical separation or three miles laterally for radar approach controls.
If you're climbing high, ATC needs to ensure vertical or horizontal radar separation between you and other traffic before you reach flight level 180.--TK
Minimum required radar separation from the MOA boundary is three miles.
When a major airport's weather drops below VFR minimums, its traffic capacity drops considerably because they must now use radar separation.
