b. Verbally obtain the receiving controller's
approval prior to making any changes to an aircraft's
flight path, altitude, or data block information while
the handoff is being initiated or after acceptance,
unless otherwise specified by a LOA or a facility
directive.
NOTE-
Those en route facilities using host software that provides
capability for passing interim altitude shall include the
specific operations and procedures for use of this
procedure in a LOA between the appropriate facilities.
c. Ensure that, prior to transferring communications:
1. Potential violations of adjacent airspace and
potential conflicts between aircraft in their own area
of jurisdiction are resolved.
JO 7110.65S 2/14/08
5-4-3
Transfer of Radar Identification
2. Necessary coordination has been accomplished with all controllers through whose area of
jurisdiction the aircraft will pass prior to entering the
receiving controller's area of jurisdiction, except
when such coordination is the receiving controller's
responsibility as stated in para 5-4-6, Receiving
Controller Handoff, and unless otherwise specified
by a LOA or a facility directive.
3. Restrictions issued to ensure separation are
passed to the receiving controller.
d. After transferring communications, continue to
comply with the requirements of subparas c1 and 2.
e. Comply with restrictions issued by the receiving
controller unless otherwise coordinated.
f. Comply with the provisions of para 2-1-17,
Radio Communications Transfer, subparas a and b.
To the extent possible, transfer communications
when the transfer of radar identification has been
accepted.
NOTE-
Before the ARTS/STARS “modify/quick look” function is
used to transfer radar identification, a facility directive
which specifies communication transfer points is required.
g. Advise the receiving controller of pertinent
information not contained in the data block or flight
progress strip unless covered in a LOA or facility
directive. Pertinent information includes:
1. Assigned heading.
2. Air speed restrictions.
3. Altitude information issued.
4. Observed track or deviation from the last
route clearance.
5. The beacon code if different from that
normally used or previously coordinated.
6. Any other pertinent information.
h. Ensure that the data block is associated with the
appropriate target.
i. Initiate verbal coordination to verify the position
of primary or nondiscrete targets when using the
automated handoff functions except for intrafacility
handoffs using single-sensor systems or multisensor
systems operating in a mosaic RDP mode.
j. Initiate verbal coordination before transferring
control of a track when “CST,” “FAIL,” “NONE,”
“NB,” “NX,” “IF,” or “NT” is displayed in the data
block.
k. Advise the receiving controller that radar
monitoring is required when the aircraft is on a direct
route initiated by ATC that exceeds usable NAVAID
distances.
l. Issue restrictions to the receiving controller
which are necessary to maintain separation from
other aircraft within your area of jurisdiction before
releasing control of the aircraft.
m. Consider the target being transferred as
identified on the receiving controller's display when
the receiving controller acknowledges receipt
verbally or has accepted an automated handoff.
n. Accomplish the necessary coordination with
any intervening controllers whose area of jurisdiction
is affected by the receiving controller's delay in the
climb or the descent of an aircraft through the vertical
limits of your area of jurisdiction when the receiving
controller advises you of that delay before accepting
the transfer of radar identification unless otherwise
specified by a LOA or a facility directive.
5-4-6. RECEIVING CONTROLLER
HANDOFF
The receiving controller shall:
a. Ensure that the target position corresponds with
the position given by the transferring controller or
that there is an appropriate association between an
automated data block and the target being transferred
before accepting a handoff.
REFERENCE-
FAAO JO 7110.65, Para 2-1-14, Coordinate Use of Airspace.
FAAO JO 7110.65, Para 2-1-15, Control Transfer.
FAAO JO 7110.65, Para 5-4-5, Transferring Controller Handoff.
b. Issue restrictions that are needed for the aircraft
to enter your sector safely before accepting the
handoff.
c. Comply with restrictions issued by the initiating
controller unless otherwise coordinated.
d. Before you issue control instructions directly to
an aircraft that is within another controller's area of
jurisdiction that will change that aircraft's heading,
route, speed, altitude, or beacon code, ensure that
coordination has been accomplished with each of the
controllers listed below whose area of jurisdiction is
affected by those instructions unless otherwise
specified by a LOA or a facility directive:
JO 7110.65S 2/14/08
5-4-4 Transfer of Radar Identification
NOTE-
Those en route facilities using host software that provides
capability for passing interim altitude shall include the
specific operations and procedures for use of this
procedure in a LOA between the appropriate facilities.
1. The controller within whose area of jurisdiction the control instructions will be issued.
2. Any intervening controller(s) through whose
area of jurisdiction the aircraft will pass.
e. After accepting a handoff from another
controller, confirm the identity of primary target by
advising the aircraft of its position, and of a beacon
target by observing a code change, an “ident” reply,
or a “standby” squawk unless one of these was used
during handoff. These provisions do not apply at
those towers and GCAs which have been delegated
the responsibility for providing radar separation
within designated areas by the parent approach
control facility and the aircraft identification is
assured by sequencing or positioning prior to the
handoff.
REFERENCE-
FAAO JO 7110.65, Para 5-9-5, Approach Separation Responsibility.
f. When using appropriate equipment, consider a
discrete beacon target's identity to be confirmed
when:
1. The data block associated with the target
being handed off indicates the computer assigned
discrete beacon code is being received, or
2. You observe the deletion of a discrete code
that was displayed in the data block, or
NOTE-
When the aircraft generated discrete beacon code does not
match the computer assigned beacon code, the code
generated will be displayed in the data block. When the
aircraft changes to the assigned discrete code, the code
disappears from the data block. In this instance, the
observance of code removal from the data block satisfies
confirmation requirements.
3. You observe the numeric display of a discrete
code that an aircraft has been instructed to squawk or
reports squawking.
g. Initiate verbal coordination prior to accepting
control of a track when “CST,” “NAT,” “NT,”
“NONE,” “NB,” “NX,” “OLD,” “OL,” “AMB,”
“AM,” or “TU” is displayed in the data block.
1. When an automated interfacility handoff
action is initiated and “AMB” or “AM” is displayed
in the full data block, advise the other facility that a
disparity exists between the position declared by their
computer and that declared by your ARTS/PIDP/
STARS system.
2. When an automated interfacility handoff
action is initiated and “NAT,” “NT,” or “TU” is
displayed in the full data block, advise the other
facility if a disparity exists between the position
declared by their computer and the actual target
position.
h. Advise the transferring controller, prior to
accepting the transfer of radar identification, that you
will delay the climb or the descent of an aircraft
through the vertical limits of the transferring
controller's area of jurisdiction, unless otherwise
specified in a LOA or a facility directive.
NOTE-
Those en route facilities using HOST software that
provides capability for passing interim altitude shall
include the specific operations and procedures for use of
this procedure in a LOA between the appropriate facilities.
i. If you decide, after accepting the transfer of
radar identification, to delay the aircraft's climb or
descent through the vertical limits of the transferring
controller's area of jurisdiction, advise the transferring controller of that decision as soon as possible.
You now have the responsibility to ensure that the
necessary coordination is accomplished with any
intervening controller(s) whose area of jurisdiction is
affected by that delay, unless otherwise specified in a
LOA or a facility directive.
NOTE-
Those en route facilities using HOST software that
provides capability for passing interim altitude shall
include the specific operations and procedures for use of
this procedure in a LOA between the appropriate facilities.
5-4-7. POINT OUT
a. The transferring controller shall:
1. Obtain verbal approval before permitting an
aircraft to enter the receiving controller's delegated
airspace. TERMINAL. Automated approval may be
utilized in lieu of verbal, provided the appropriate
automation software is operational (automated point
out function), and the procedures are specified in a
facility directive/LOA.
2. Obtain the receiving controller's approval
before making any changes to an aircraft's flight path,
altitude, or data block information after the point out
has been approved.
JO 7110.65S 2/14/08
5-4-5
Transfer of Radar Identification
NOTE-
Those en route facilities using HOST software that
provides capability for passing interim altitude shall
include the specific operations and procedures for use of
this procedure in a LOA between the appropriate facilities.
3. Comply with restrictions issued by the
receiving controller unless otherwise coordinated.
4. Be responsible for subsequent radar handoffs
and communications transfer, including flight data
revisions and coordination, unless otherwise agreed
to by the receiving controller or as specified in a LOA.
b. The receiving controller shall:
1. Ensure that the target position corresponds
with the position given by the transferring controller
or that there is an association between a computer
data block and the target being transferred prior to
approving a point out.
2. Be responsible for separation between point
out aircraft and other aircraft for which he/she has
separation responsibility.
3. Issue restrictions necessary to provide
separation from other aircraft within his/her area of
jurisdiction.
5-4-8. AUTOMATED INFORMATION
TRANSFER (AIT)
Transfer radar identification, altitude control, and/or
en route fourth line control information, without
verbal coordination under the following conditions:
a. During radar handoff; and
b. Via information displayed in full data blocks;
and
c. Within the same facility, except as provided in
para 5-4-9, Interfacility Automated Information
Transfer; and
d. When following procedures specified in your
facility AIT directive.
REFERENCE-

INFORMATION TRANSFER
EN ROUTE
Transfer radar identification without verbal coordination under the following conditions:
a. During radar handoff; and
b. Via information displayed in full data blocks;
and
c. On aircraft at assigned altitude in level flight;
and
d. Only the first sector within the receiving facility
shall utilize the procedure; and
e. When following procedures specified in your
facility AIT directive and LOA.
5-4-10. PREARRANGED COORDINATION
Prearranged coordination allowing aircraft under
your control to enter another controller's area of
jurisdiction may only be approved provided
procedures are established and published in a facility
directive/LOA in accordance with FAAO JO 7210.3,
para 3-7-7, Prearranged Coordination.
NOTE-
Under no circumstances may one controller permit an
aircraft to enter another's airspace without proper
coordination. Coordination can be accomplished by
several means; i.e., radar handoff, automated information
transfer, verbal, point-out, and by prearranged coordination procedures identified in a facility directive that clearly
describe the correct application. Airspace boundaries
should not be permitted to become barriers to the efficient
movement of traffic. In addition, complete coordination,
awareness of traffic flow, and understanding of each
position's responsibility concerning penetration of another's airspace cannot be overemphasized.

5-5-2 Radar Separation
5-5-4. MINIMA
Separate aircraft by the following minima:
a. Broadband Radar System or Digital Terminal
Automation System (DTAS):
NOTE-
Includes single sensor long range radar mode.
1. When less than 40 miles from the antenna3_miles.
2. When 40 miles or more from the antenna5_miles.
3. TERMINAL. For single sensor ASR-9 with
Mode S, when less than 60 miles from the antenna -
3 miles.
NOTE-
Wake turbulence procedures specify increased separation
minima required for certain classes of aircraft because of
the possible effects of wake turbulence.
b. Stage A/DARC, MEARTS Mosaic Mode,
Terminal Mosaic/Multi-Sensor Mode:
NOTE-
Mosaic/Multi-Sensor Mode combines radar input from 2
to 16 sites into a single picture utilizing a mosaic grid
composed of radar sort boxes.
1. Below FL 600- 5 miles.
2. At or above FL 600- 10 miles.
3. For areas meeting all of the following
conditions:
(a) Radar site adaptation is set to single
sensor.
(b) Significant operational advantages can be
obtained.
(c) Within 40 miles of the antenna.
(d) Below FL 180.
(e) Facility directives specifically define the
area where the separation can be applied. Facility
directives may specify 3 miles.
REFERENCE-
FAAO JO 7210.3, Para 8-2-1, Single Site Coverage Stage A
Operations.
FAAO JO 7210.3, Para 11-8-15, Single Site Coverage ATTS
Operations.
4. When transitioning from terminal to en route
control, 3 miles increasing to 5 miles or greater,
provided:
(a) The aircraft are on diverging routes/
courses, and/or
(b) The leading aircraft is and will remain
faster than the following aircraft; and
(c) Separation constantly increasing and the
first center controller will establish 5 NM or other
appropriate form of separation prior to the aircraft
departing the first center sector; and
(d) The procedure is covered by a letter of
agreement between the facilities involved and limited
to specified routes and/or sectors/positions.
c. MEARTS Mosaic Mode:
NOTE1. Sensor Mode displays information from the radar input
of a single site.
2. Procedures to convert MEARTS Mosaic Mode to
MEARTS Sensor Mode at each PVD/MDM will be
established by facility directive.
1. When less than 40 miles from the antenna3_miles.
2. When 40 miles or more from the antenna5_miles.
d. STARS Multi-Sensor Mode:
NOTE1. In Multi-Sensor Mode, STARS displays targets as filled
and unfilled boxes, depending upon the target's distance
from the radar site providing the data. Since there is
presently no way to identify which specific site is providing
data for any given target, utilize separation standards for
targets 40 or more miles from the antenna.
2. When operating in STARS Single Sensor Mode, if TRK
appears in the data block, handle in accordance with
para_5-3-7, Identification Status, subpara b, and take
appropriate steps to establish nonradar separation.
3. TRK appears in the data block whenever the aircraft is
being tracked by a radar site other than the radar currently
selected. Current equipment limitations preclude a target
from being displayed in the single sensor mode; however,
a position symbol and data block, including altitude
information, will still be displayed. Therefore, low altitude
alerts shall be provided in accordance with para 2-1-6,
Safety Alert.
WAKE TURBULENCE APPLICATION
e. Separate aircraft operating directly behind, or
directly behind and less than 1,000 feet below, or
following an aircraft conducting an instrument
approach by:
JO 7110.65S 2/14/08
5-5-3
Radar Separation
NOTE1. When applying wake turbulence separation criteria,
directly behind means an aircraft is operating within
2500_feet of the flight path of the leading aircraft over the
surface of the earth.
2. Consider parallel runways less than 2,500 feet apart as
a single runway because of the possible effects of wake
turbulence.
1. Heavy behind heavy- 4 miles.
2. Large/heavy behind B757- 4 miles.
3. Small behind B757- 5 miles.
4. Small/large behind heavy - 5 miles.
WAKE TURBULENCE APPLICATION
f. TERMINAL. In addition to subpara e, separate
an aircraft landing behind another aircraft on the
same runway, or one making a touch-and-go,
stop-and-go, or low approach by ensuring the
following minima will exist at the time the preceding
aircraft is over the landing threshold:
NOTE-
Consider parallel runways less than 2,500 feet apart as a
single runway because of the possible effects of wake
turbulence.
1. Small behind large- 4 miles.
2. Small behind B757- 5 miles.
3. Small behind heavy- 6 miles.
g. TERMINAL. 2.5 nautical miles (NM) separation is authorized between aircraft established on the
final approach course within 10 NM of the landing
runway when operating in single sensor slant range
mode and aircraft remains within 40 miles of the
antenna and:
1. The leading aircraft's weight class is the same
or less than the trailing aircraft;
2. Heavy aircraft and the Boeing 757 are
permitted to participate in the separation reduction as
the trailing aircraft only;
3. An average runway occupancy time of
50_seconds or less is documented;
4. CTRDs are operational and used for quick
glance references;

5-5-5. VERTICAL APPLICATION
Aircraft not laterally separated, may be vertically
separated by one of the following methods:
a. Assign altitudes to aircraft, provided valid
Mode_C altitude information is monitored and the
applicable separation minima is maintained at all
times.
REFERENCE-
FAAO JO 7110.65, Para 4-5-1, Vertical Separation Minima.

FAAO JO 7110.65, Para 7-8-3, Separation.
FAAO JO 7110.65, Para 7-9-4, Separation.
b. Assign an altitude to an aircraft after the aircraft
previously at that altitude has been issued a
climb/descent clearance and is observed (valid
Mode_C), or reports leaving the altitude.
NOTE1. Consider known aircraft performance characteristics,
pilot furnished and/or Mode C detected information which
indicate that climb/descent will not be consistent with the
rates recommended in the AIM.
2. It is possible that the separation minima described in
para 4-5-1, Vertical Separation Minima, para_7-7-3,
Separation, para 7-8-3, Separation, or para_7-9-4,
Separation, might not always be maintained using
subpara_b. However, correct application of this procedure
will ensure that aircraft are safely separated because the
first aircraft must have already vacated the altitude prior
to the assignment of that altitude to the second aircraft.

and you have observed that they have passed each
other; or aircraft are on same or crossing courses and
one aircraft has crossed the projected course of the
other and the angular difference between their
courses is at least 15 degrees.
2. The tracks are monitored to ensure that the
primary targets, beacon control slashes, or full digital
terminal system primary and/or beacon target
symbols will not touch.
REFERENCE-

other aircraft, including position, direction, type; and
3. One pilot reports having seen the other
aircraft and that the aircraft have passed each other;
and
4. You have observed that the radar targets have
passed each other; and
5. You have advised the pilots if either aircraft
is classified as a heavy jet/B757 aircraft.
6. Although vertical separation may be discontinued, the requirements of para 5-5-4, Minima,
subparas e and f must be applied when operating
behind a heavy jet/B757.
EXAMPLE“Traffic, twelve o'clock, Boeing Seven Twenty Seven,
opposite direction. Do you have it in sight?”
(If the answer is in the affirmative):
“Report passing the traffic.”
(When pilot reports passing the traffic and the radar
targets confirm that the traffic has passed, issue
appropriate control instructions.)
5-5-8. ADDITIONAL SEPARATION FOR
FORMATION FLIGHTS
Because of the distance allowed between formation
aircraft and lead aircraft, additional separation is
necessary to ensure the periphery of the formation is
adequately separated from other aircraft, adjacent
airspace, or obstructions. Provide supplemental
separation for formation flights as follows:
a. Separate a standard formation flight by adding
1 mile to the appropriate radar separation minima.
REFERENCE-
FAAO JO 7110.65, Para 2-1-13, Formation Flights.
FAAO JO 7110.65, Para 5-5-1, Application.
FAAO JO 7110.65, Para 7-7-3, Separation.
P/CG Term- Formation Flight.
b. Separate two standard formation flights from
each other by adding 2 miles to the appropriate
separation minima.

5-5-5
Radar Separation
c. Separate a nonstandard formation flight by
applying the appropriate separation minima to the
perimeter of the airspace encompassing the nonstandard formation or from the outermost aircraft of the
nonstandard formation whichever applies.
d. If necessary for separation between a nonstandard formation and other aircraft, assign an
appropriate beacon code to each aircraft in the
formation or to the first and last aircraft in-trail.
NOTE-
The additional separation provided in para 5-5-8,
Additional Separation for Formation Flights, is not
normally added to wake turbulence separation when a
formation is following a heavier aircraft since none of the
formation aircraft are likely to be closer to the heavier
aircraft than the lead aircraft (to which the prescribed
wake turbulence separation has been applied).
REFERENCE-
FAAO JO 7110.65, Para 9-2-12, Military Aerial Refueling.
5-5-9. SEPARATION FROM
OBSTRUCTIONS
a. Except in En Route Stage A/DARC or
Stage_A/EDARC, separate aircraft from obstructions
depicted on the radar display by the following
minima:
1. When less than 40 miles from the antenna3_miles.
2. When 40 miles or more from the antenna5_miles.
b. Except in En Route Stage A/DARC or
Stage_A/EDARC, vertical separation of aircraft
above an obstruction depicted on the radar display
may be discontinued after the aircraft has passed it.
c. En Route Stage A/DARC or Stage A/EDARC,
apply the radar separation minima specified in
para_5-5-4, Minima, subpara b1.
5-5-10. ADJACENT AIRSPACE
a. If coordination between the controllers concerned has not been effected, separate
radar-controlled aircraft from the boundary of
adjacent airspace in which radar separation is also
being used by the following minima:
REFERENCE-
FAAO JO 7110.65, Para 2-1-14, Coordinate Use of Airspace.
1. When less than 40 miles from the antenna1_1 /2 miles.
2. When 40 miles or more from the antenna2_1 /2 miles.
3. En route Stage A/DARC or Stage A/EDARC:
(a) Below Flight Level 600- 2 1
/2 miles.
(b) Flight Level 600 and above- 5 miles.
b. Separate radar-controlled aircraft from the
boundary of airspace in which nonradar separation is
being used by the following minima:
1. When less than 40 miles from the antenna3_miles.
2. When 40 miles or more from the antenna5_miles.
3. En route Stage A/DARC or Stage A/EDARC:
(a) Below Flight Level 600- 5 miles.
(b) Flight Level 600 and above- 10 miles.
c. The provisions of subparas a and b do not apply
to VFR aircraft being provided Class B, Class C, or
TRSA services. Ensure that the targets of these
aircraft do not touch the boundary of adjacent
airspace.
d. VFR aircraft approaching Class B, Class C,
Class D, or TRSA airspace which is under the
control jurisdiction of another air traffic control
facility should either be provided with a radar handoff
or be advised that radar service is terminated, given
their position in relation to the Class B, Class C,
Class_D, or TRSA airspace, and the ATC frequency,
if known, for the airspace to be entered. These actions
should be accomplished in sufficient time for the pilot
to obtain the required ATC approval prior to entering
the airspace involved, or to avoid the airspace. |
