Radar Separation 5-5-1
Section 5. Radar Separation
5-5-1. APPLICATION
a. Radar separation shall be applied to all RNAV
aircraft operating on a random (impromptu) route at
or below FL 450 and to all published Q routes in the
conterminous United States.
b. Radar separation may be applied between:
1. Radar identified aircraft.
2. 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.
3. A radar‐identified aircraft and one not
radar‐identified when either is cleared to climb/
descend through the altitude of the other provided:
(a) 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
(b) Flight data on the aircraft not radaridentified
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
(c) The airspace within which radar separation
is applied is not less than the following number
of miles from the edge of the radar display:
(1) When less than 40 miles from the
antenna- 6 miles;
(2) When 40 miles or more from the
antenna- 10 miles;
(3) Narrowband radar operations-
10miles; and
(d) 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
(e) 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.
