2. VFR Flights.
(a) Arriving aircraft must obtain an ATC
clearance prior to entering Class B airspace and must
contact ATC on the appropriate frequency, and in
relation to geographical fixes shown on local charts.
Although a pilot may be operating beneath the floor
of the Class B airspace on initial contact, communications
with ATC should be established in relation to the
points indicated for spacing and sequencing purposes.
(b) Departing aircraft require a clearance to
depart Class B airspace and should advise the
clearance delivery position of their intended altitude
and route of flight. ATC will normally advise VFR
aircraft when leaving the geographical limits of the
Class B airspace. Radar service is not automatically
terminated with this advisory unless specifically
stated by the controller.
(c) Aircraft not landing or departing the
primary airport may obtain an ATC clearance to
transit the Class B airspace when traffic conditions
permit and provided the requirements of 14 CFR
Section 91.131 are met. Such VFR aircraft are
encouraged, to the extent possible, to operate at
altitudes above or below the Class B airspace or
transit through established VFR corridors. Pilots
operating in VFR corridors are urged to use frequency
122.750 MHz for the exchange of aircraft position
information.
e. ATC Clearances and Separation. An ATC
clearance is required to enter and operate within
Class B airspace. VFR pilots are provided sequencing
and separation from other aircraft while operating
within Class B airspace.

NOTE−
1. Separation and sequencing of VFR aircraft will be
suspended in the event of a radar outage as this service is
dependent on radar. The pilot will be advised that the
service is not available and issued wind, runway
information and the time or place to contact the tower.
2. Separation of VFR aircraft will be suspended during
CENRAP operations. Traffic advisories and sequencing to
the primary airport will be provided on a workload
permitting basis. The pilot will be advised when center
radar presentation (CENRAP) is in use.
1. VFR aircraft are separated from all VFR/IFR
aircraft which weigh 19,000 pounds or less by a
minimum of:
(a) Target resolution, or
(b) 500 feet vertical separation, or
(c) Visual separation.
2. VFR aircraft are separated from all VFR/IFR
aircraft which weigh more than 19,000 and turbojets
by no less than:
(a) 1 1/2 miles lateral separation, or
(b) 500 feet vertical separation, or
(c) Visual separation.
3. This program is not to be interpreted as
relieving pilots of their responsibilities to see and
avoid other traffic operating in basic VFR weather
conditions, to adjust their operations and flight path
as necessary to preclude serious wake encounters, to
maintain appropriate terrain and obstruction clearance
or to remain in weather conditions equal to or
better than the minimums required by 14 CFR
Section 91.155. Approach control should be advised
and a revised clearance or instruction obtained when
compliance with an assigned route, heading and/or
altitude is likely to compromise pilot responsibility
with respect to terrain and obstruction clearance,
vortex exposure, and weather minimums.
4. ATC may assign altitudes to VFR aircraft that
do not conform to 14 CFR Section 91.159.
“RESUME APPROPRIATE VFR ALTITUDES”
will be broadcast when the altitude assignment is no
longer needed for separation or when leaving Class B
airspace. Pilots must return to an altitude that
conforms to 14 CFR Section 91.159.
f. Proximity operations. VFR aircraft operating
in proximity to Class B airspace are cautioned against
operating too closely to the boundaries, especially
where the floor of the Class B airspace is 3,000 feet
or less or where VFR cruise altitudes are at or near the
floor of higher levels. Observance of this precaution
will reduce the potential for encountering an aircraft
operating at the altitudes of Class B floors.
Additionally, VFR aircraft are encouraged to utilize
the VFR Planning Chart as a tool for planning flight
in proximity to Class B airspace. Charted VFR
Flyway Planning Charts are published on the back of
the existing VFR Terminal Area Charts.

a. Definition. Generally, that airspace from the
surface to 4,000 feet above the airport elevation
