Rather tough for a /U aircraft.
Regardless, the FAA has never specified what form a Class B clearance should take.
7-9-1. APPLICATION
Apply Class B services and procedures within the
designated Class B airspace.
a. No person may operate an aircraft within
ClassB airspace unless:
1. The aircraft has an operable two‐way radio
capable of communications with ATC on appropriate
frequencies for that Class B airspace.
2. The aircraft is equipped with the applicable
operating transponder and automatic altitude report
ing equipment specified in para (a) of 14 CFR
Section91.215, except as provided in para (d) of that
section.
7-9-2. VFR AIRCRAFT IN CLASS B
AIRSPACE
a. VFR aircraft must obtain an ATC clearance to
operate in Class B airspace.
REFERENCE-
FAAO JO 7110.65, Para 2-1-18, Operational Requests.
FAAO JO 7110.65, Para 2-4-22, Airspace Classes.
PHRASEOLOGY-
CLEARED THROUGH/TO ENTER/OUT OF BRAVO
AIRSPACE,
and as appropriate,
VIA (route). MAINTAIN (altitude) WHILE IN BRAVO
AIRSPACE.
or
CLEARED AS REQUESTED.
(Additional instructions, as necessary.)
REMAIN OUTSIDE BRAVO AIRSPACE. (When
necessary, reason and/or additional instructions.)
NOTE-
1. Assignment of radar headings, routes, or altitudes is
based on the provision that a pilot operating in accordance
with VFR is expected to advise ATC if compliance will
cause violation of any part of the CFR.
2. Separation and sequencing for VFR aircraft is
dependent upon radar. Efforts should be made to segregate
VFR traffic from IFR traffic flows when a radar outage
occurs.
b. Approve/deny requests from VFR aircraft to
operate in Class B airspace based on workload,
operational limitations and traffic conditions.
c. Inform the pilot when to expect further
clearance when VFR aircraft are held either inside or
outside Class B airspace.
d. Inform VFR aircraft when leaving Class B
airspace.
PHRASEOLOGY-
LEAVING (name) BRAVO AIRSPACE,
and as appropriate,
RESUME OWN NAVIGATION, REMAIN THIS
FREQUENCY FOR TRAFFIC ADVISORIES, RADAR
SERVICE TERMINATED, SQUAWK ONE TWO ZERO
ZERO.
7-9-3. METHODS
a. To the extent practical, clear large turbine
engine‐powered airplanes to/from the primary airport
using altitudes and routes that avoid VFR corridors
and airspace below the Class B airspace floor where
VFR aircraft are operating.
NOTE-
Pilots operating in accordance with VFR are expected to
advise ATC if compliance with assigned altitudes,
headings, or routes will cause violation of any part of the
CFR.
b. Vector aircraft to remain in Class B airspace
after entry. Inform the aircraft when leaving and
reentering Class B airspace if it becomes necessary to
extend the flight path outside Class B airspace for
spacing.
NOTE-
14 CFR Section 91.131 states that “Unless otherwise
authorized by ATC, each person operating a large turbine
engine‐powered airplane to or from a primary airport for
which a Class B airspace area is designated must operate
at or above the designated floors of the Class B airspace
area while within the lateral limits of that area.” Such
authorization should be the exception rather than the rule.
