Provide radar services only if you are personally satisfied that the radar presentation and equipment performance
is adequate for the service being provided.
NOTE: The provision of radar services is not limited to the distance and altitude parameters obtained during the
commissioning flight check. FAA Order 8200.1, United States Standard Flight Inspection Manual, Chapter 14,
Surveillance, describes the surveillance flight inspection procedures.
Notify the OS/CIC of any radar malfunctions or unexpected outages. Advise adjacent facilities when appropriate.
Outside Class A airspace, or where mix of Class A airspace/non-Class A airspace exists, only when:
(a) Additional coverage is provided by secondary radar beyond that of the primary radar, or
(b) The primary radar is temporarily unusable or out of service. Advise pilots when these conditions
exist, or
PHRASEOLOGY
PRIMARY RADAR UNAVAILABLE (describe location). RADAR SERVICES AVAILABLE ON TRANSPONDER OR ADS-B
EQUIPPED AIRCRAFT ONLY.
NOTE:
1. Advisory may be omitted when provided on ATIS and pilot indicates having ATIS information.
2. This provision is to authorize secondary radar only operations where there is no primary radar
available and the condition is temporary.
(c) A secondary radar system is the only source of radar data for the area of service. TERMINAL. Advise pilots when these
conditions exist.
NOTE: Advisory may be omitted when provided on ATIS or by other appropriate notice to pilots.
TERMINAL. Do not use secondary radar only to conduct surveillance (ASR) final
approaches unless an emergency exists and the pilot concurs.
All procedures and requirements relating to ATC services using secondary radar targets apply to ATC services
provided to targets derived from ADS-B and WAM.
NOTE: Targets derived from WAM cannot be used to provide 3NM separation in the EAS. 3NM targets are not derived
from WAM within the EAS.
FAA Order JO 7210.3, Para 3-6-2, ATC Surveillance Source Use.
5-1-3. ELECTRONIC ATTACK (EA) ACTIVITY
Refer all EA activity requests to the appropriate center supervisor.
REFERENCE
FAA Order JO 7610.4, Chapter 2, Section 7, Electronic Attack (EA) and Testing Coordination.
NOTE: EA activity can subsequently result in a request to apply EA videos to the radar system which may
necessitate the decertification of the narrow band search radar. The Systems Engineer should be consulted
concerning the effect of EA on the operational use of the narrow band radar prior to approving/disapproving
requests to conduct EA activity.
When EA activity interferes with the operational use of radar:
EN ROUTE. Request the responsible military unit or aircraft, if initial
request was received directly from pilot, to suspend the activity.
TERMINAL. Request suspension of the activity through the ARTCC. If immediate
cessation of the activity is required, broadcast the request directly to the EA aircraft on the emergency
frequency. Notify the ARTCC of direct broadcast as soon as possible.
When previously suspended activity will no longer interfere:
EN ROUTE. Inform the NORAD unit or aircraft that it may be resumed.
TERMINAL. Inform the ARTCC or aircraft that it may be resumed. Obtain
approval from the ARTCC prior to broadcasting a resume clearance directly to the aircraft.
In each stop request, include your facility name, type of EA activity (chaff dispensing- “stream”/“burst” or
electronic jamming- “buzzer”), radar band affected and, when feasible, expected duration of suspension.
PHRASEOLOGY
BIG PHOTO (identification, if known) (name) CENTER/TOWER/APPROACH CONTROL.
To stop EA activity:
STOP STREAM/BURST IN AREA (area name) (degree and distance from facility),
or
STOP BUZZER ON (frequency band or channel).
To resume EA activity:
RESUME STREAM/BURST,
or
RESUME BUZZER ON (frequency band or channel).
5-1-4. MERGING TARGET PROCEDURES
Except while they are established in a holding pattern, apply merging target procedures to all radar identified:
Issue traffic information to the aircraft listed in subparagraph a whose targets appear likely to merge unless
the
aircraft are separated by more than the appropriate vertical separation minima.
“United Sixteen and American Twenty-Five, traffic twelve o'clock, one zero miles, opposite direction,
eastbound Seven Thirty-Seven at flight level three three zero, westbound Airbus Three Twenty at flight level
three two zero.”
When both aircraft in subparagraph b are in RVSM airspace, and vertically separated by 1,000 feet, and either
pilot
reports they are unable to maintain RVSM due to turbulence or mountain wave, use vectors to prevent the targets
from merging.
EXAMPLE
“Delta One Twenty Three, fly heading two niner zero, vector for traffic. Traffic twelve o'clock, one zero
miles, opposite direction, Seven Thirty-Seven, eastbound at flight level three one zero.”
If the pilot requests, vector their aircraft to avoid merging targets with the previously issued traffic.
NOTE: Because aircraft closure rates can be rapid, issue traffic with enough time for the pilot to decide if a
vector is necessary.
If unable to provide vector service, inform the pilot.
NOTE: The phraseology “Unable RVSM due turbulence (or mountain wave)” is only intended for severe turbulence
or other weather encounters with altitude deviations of approximately 200 feet or more.
5-1-5. HOLDING PATTERN SURVEILLANCE
Provide radar surveillance of outer fix holding pattern airspace areas, or any portions thereof, shown on your radar
scope (displayed on the video map or scribed on the map overlay) whenever aircraft are holding there. Attempt to
detect any aircraft that stray outside the area. If you detect an aircraft straying outside the area, assist it to
return to the assigned airspace.
5-1-6. DEVIATION ADVISORIES
Inform an aircraft when it is observed in a position and on a track which will obviously cause the aircraft to
deviate from its protected airspace area. If necessary, help the aircraft to return to the assigned protected
airspace.
NOTE:
1. RNAV ATS routes have a width of 8 miles and laterally protected airspace of 4 miles on each side of the route
centerline
2. Navigation system performance requirements for operations on RNAV ATS routes require the aircraft system be
capable of remaining within 2 miles of the route centerline. Aircraft approaching this limit may be experiencing a
navigation system error or failure.
FAA Order 7400.2, Para 20-5-2. RNAV Route Criteria.
AC90-100A, U.S. Terminal and En Route Area Navigation (RNAV) Operations, Para 8a. Navigation System Accuracy
5-1-7. MANUAL FIX POSTING
EN ROUTE
Manually record the observed or reported time over a fix at least once for each controlled aircraft in your sector
of responsibility when the flight progress recording components of the EAS FDP are not operational.
REFERENCE
FAA Order JO 7210.3, Para 6-1-6, Flight Progress Strip Usage.
5-1-8. POSITION REPORTING
If necessary, you may request an aircraft to provide an estimate or report over a specific fix. After an aircraft
receives the statement “radar contact” from ATC, it discontinues reporting over compulsory reporting points. It
resumes normal position reporting when ATC informs it “radar contact lost” or “radar service terminated.”
When required, inform an aircraft of its position with respect to a fix or airway.
PHRASEOLOGY
OVER/PASSING (fix).
(Number of miles) MILES FROM (fix).
(Number of miles) MILES (direction) OF (fix, airway, or location).
CROSSING/JOINING/DEPARTING (airway or route).
INTERCEPTING/CROSSING (name of NAVAID) (specified) RADIAL.
5-1-9. RADAR SERVICE TERMINATION
Inform aircraft when radar service is terminated.
PHRASEOLOGY
RADAR SERVICE TERMINATED (nonradar routing if required).
Radar service is automatically terminated and the aircraft needs not be advised of termination when:
NOTE: Termination of radar monitoring when conducting simultaneous ILS approaches is prescribed in paragraph
5-9-7, Simultaneous Independent Approaches- Dual Triple.
An aircraft cancels its IFR flight plan, except within Class B airspace, Class C airspace, TRSA, or where
basic radar service is provided.
An aircraft conducting an instrument, visual, or contact approach has landed or has been instructed to change
to advisory frequency.
At tower-controlled airports where radar coverage does not exist to within 1/2 mile of the end of the runway,
arriving aircraft must be informed when radar service is terminated.
REFERENCE
FAA Order JO 7210.3, Para 10-5-6, Radar Tolerances.
TERMINAL. An arriving VFR aircraft receiving radar service to a
tower-controlled airport within Class B airspace, Class C airspace, TRSA, or where basic radar service is
provided has landed, or to all other airports, is instructed to change to tower or advisory frequency.
