JO 7110.65 — Air Traffic Control
JO 7110.65 5-5-1
APPLICATION
Radar separation must be applied to all RNAV aircraft operating at and below FL450 on Q routes or random RNAV routes, excluding oceanic airspace. EXCEPTION. GNSS-equipped aircraft /G, /L, /S, and /V on point‐to‐point routes, or transitioning between two point‐to‐point routes via an impromptu route.

Radar separation may be applied between: Radar identified aircraft.
An aircraft taking off and another radar identified aircraft when the aircraft taking off will be radar‐identified within 1 mile of the runway end.
A radar‐identified aircraft and one not radar‐identified when either is cleared to climb/descend through the altitude of the other provided: The performance of the radar system is adequate and, as a minimum, primary radar targets or ASR-9/Full Digital Radar Primary Symbol targets are being displayed on the display being used within the airspace within which radar separation is being applied; and
Flight data on the aircraft not radar‐identified indicate it is a type which can be expected to give adequate primary/ASR-9/Full Digital Radar Primary Symbol return in the area where separation is applied; and
The airspace within which radar separation is applied is not less than the following number of miles from the edge of the radar display: When less than 40 miles from the antenna- 6 miles;
When 40 miles or more from the antenna- 10 miles ;
Narrowband radar operations- 10 miles; and
Radar separation is maintained between the radar‐identified aircraft and all observed primary, ASR-9/Full Digital Radar Primary Symbol, and secondary radar targets until nonradar separation is established from the aircraft not radar identified; and
When the aircraft involved are on the same relative heading, the radar‐identified aircraft is vectored a sufficient distance from the route of the aircraft not radar identified to assure the targets are not superimposed prior to issuing the clearance to climb/descend. REFERENCE-
