RADAR SEPARATION MINIMA
a. Application. Separate radar-identified aircraft by 3 miles if less than 40 miles from the antenna,
or by 5 miles if 40 miles or more from the antenna.
b. Passing or Diverging. Vertical separation between aircraft may be discontinued when--
(1) You observe that they have passed each other or that one has crossed the projected course of
another.
(2) Their tracks are monitored to assure that their primary targets or beacon control slashes will
not touch.
(3) Their courses diverge by at least 15 degrees.
c. Departure and Arrival. Separate a departing aircraft from an arriving aircraft on final approach
by a minimum of 2 miles if separation will increase to a minimum of 3 miles (5 miles if 40 miles or
more from the antenna) within one minute after takeoff.
d. Adjacent Airspace.
(1) If the coordination between the controllers concerned has not been affected, separate radar-
controlled aircraft from the boundary of adjacent airspace in which radar separation is also being used.
This separation should be 1 miles when less than 40 miles from the antenna or 2 miles when 40
miles or more from the antenna.
(2) Separate radar-controlled aircraft from the boundary of airspace in which nonradar separation
is being used. This separation should be a minimum of 3 miles when less than 40 miles from antenna or
5 miles when 40 miles or more from the antenna.
e. Edge of Scope. Separate a radar-controlled aircraft climbing or descending through the altitude
of an aircraft that has been tracked to the edge of the scope or display. The minimum separation should
be 3 miles (5 miles when 40 miles or more from the antenna) from the edge of the scope until nonradar
separation has been established.
NOTE: Sequence arriving aircraft that are conducting radar approaches to ensure a minimum of 3 miles
separation or a predetermined distance to accommodate the acceptance rate of the runway or final
control.
f. Beacon Target Displacement. When using a radar display with a previously specified beacon
target displacement to
