but is not mandatory. Traffic information is provided
on a workload permitting basis. Standard radar
separation between VFR or between VFR and IFR
aircraft is not provided.
39.1.5.1Pilots of arriving VFR aircraft should
initiate radio contact on the publicized frequency
with approach control when approximately 25 miles
from the airport at which sequencing services are
being provided. On initial contact by VFR aircraft,
approach control will assume that sequencing service
is requested. After radar contact is established, the
pilot may use pilot navigation to enter the traffic
pattern or, depending on traffic conditions, approach
control may provide the pilot with routings or vectors
necessary for proper sequencing with other participating
VFR and IFR traffic en route to the airport.
When a flight is positioned behind a preceding
aircraft and the pilot reports having that aircraft in
sight, the pilot will be instructed to follow the
preceding aircraft. THE ATC INSTRUCTION TO
FOLLOW THE PRECEDING AIRCRAFT DOES
NOT AUTHORIZE THE PILOT TO COMPLY
WITH ANY ATC CLEARANCE OR INSTRUCTION
ISSUED TO THE PRECEDING AIRCRAFT.
If other nonparticipating" or local" aircraft are in
the traffic pattern, the tower will issue a landing
sequence. If an arriving aircraft does not want radar
service, the pilot should state NEGATIVE RADAR
SERVICE" or make a similar comment, on initial
contact with approach control.
39.1.5.2Pilots of departing VFR aircraft are
encouraged to request radar traffic information by
notifying ground control on initial contact with their
request and proposed direction of flight.
EXAMPLE−
Xray ground control, November One Eight Six, Cessna One
Seventy Two, ready to taxi, VFR southbound at 2,500, have
information bravo and request radar traffic information.
NOTE−
Following takeoff, the tower will advise when to contact
departure control.
39.1.5.3Pilots of aircraft transiting the area and in
radar contact/communication with approach control
will receive traffic information on a controller
workload permitting basis. Pilots of such aircraft
should give their position, altitude, aircraft call sign,
aircraft type, radar beacon code (if transponder
equipped), destination, and/or route of flight.
39.2Terminal Radar Service Area (TRSA)
Service (Radar Sequencing and Separation
Service for VFR Aircraft in a TRSA).
39.2.1This service has been implemented at certain
terminal locations. The service is advertised in the
Airport/Facility Directory. The purpose of this
service is to provide separation between all
participating VFR aircraft and all IFR aircraft
operating within the airspace defined as the TRSA.
Pilot participation is urged but is not mandatory.
39.2.2If any aircraft does not want the service, the
pilot should state NEGATIVE TRSA SERVICE" or
make a similar comment, on initial contact with
approach control or ground control, as appropriate.
39.2.3TRSAs are depicted on sectional aeronautical
charts and listed in the Airport/Facility Directory.
39.2.4While operating within a TRSA, pilots are
provided TRSA service and separation as prescribed
in this paragraph. In the event of a radar outage,
separation and sequencing of VFR aircraft will be
suspended as this service is dependent on radar. The
pilot will be advised that the service is not available
and will be issued wind, runway information, and the
time or place to contact the tower. Traffic information
will be provided on a workload permitting basis.

39.2.5Visual separation is used when prevailing
conditions permit and it will be applied as follows:
39.2.5.1When a VFR flight is positioned behind a
preceding aircraft and the pilot reports having that
aircraft in sight, the pilot will be instructed by ATC
tofollow the preceding aircraft. THE ATC
INSTRUCTIONTOFOLLOWTHEPRECEDING
AIRCRAFT DOES NOT AUTHORIZE THE PILOT
TO COMPLY WITH ANY ATC CLEARANCE OR
INSTRUCTION ISSUED TO THE PRECEDING
AIRCRAFT. Radar service will be continued to the
runway.
39.2.5.2If other nonparticipating" or local"
aircraft are in the traffic pattern, the tower will issue
a landing sequence.
39.2.5.3Departing VFR aircraft may be asked if
they can visually follow a preceding departure out of
the TRSA. The pilot will be instructed to follow the
other aircraft provided that the pilot can maintain
