(b) 

The pilot

in

command holds a recre-

ational pilot certificate and has met the requirements 
of 14 CFR Section 61.101; or 

(c) 

The pilot

in

command holds a sport pilot 

certificate and has met the requirements of 14 CFR 
Section 61.325; or 

(d) 

The aircraft is operated by a student pilot: 

(1) 

Who seeks a private pilot certificate and 

has met the requirements of 14 CFR Section 61.95. 

(2) 

Who seeks a recreational pilot or sport 

pilot certificate and has met the requirements of 14 
CFR Section 61.94. 

4. 

Unless otherwise authorized by ATC, each 

person operating a large turbine engine-powered 
airplane to or from a primary airport must operate at 
or above the designated floors while within the lateral 
limits of Class B airspace. 

5. 

Unless otherwise authorized by ATC, each 

aircraft must be equipped as follows: 

(a) 

For IFR operations, an operable VOR or 

TACAN receiver or an operable and suitable RNAV 
system; and 

(b) 

For all operations, a two-way radio 

capable of communications with ATC on appropriate 
frequencies for that area; and 

(c) 

Unless otherwise authorized by ATC, an 

operable radar beacon transponder with automatic 
altitude reporting capability and operable ADS

Out equipment. 

NOTE

 

ATC may, upon notification, immediately authorize a 
deviation from the altitude reporting equipment require-
ment; however, a request for a deviation from the 4096 
transponder equipment requirement must be submitted to 
the controlling ATC facility at least one hour before the 
proposed operation. A request for a deviation from the 
ADS

B equipage requirement must be submitted using the 

FAA’s automated web authorization tool at least one hour 
but not more than 24 hours before the proposed operation.

6.  Mode C Veil. 

The airspace within 30 nauti-

cal miles of an airport listed in Appendix D, Section 1 
of 14 CFR Part 91 (generally primary airports within 
Class B airspace areas), from the surface upward to 
10,000 feet MSL. Unless otherwise authorized by 

ATC, aircraft operating within this airspace must be 
equipped with an operable radar beacon transponder 
with automatic altitude reporting capability and 
operable ADS

B Out equipment. 

However, aircraft that were not originally certificated 
with an engine

driven electrical system or that have 

not subsequently been certified with a system 
installed may conduct operations within a Mode C 
veil provided the aircraft remains outside Class A, B 
or C airspace; and below the altitude of the ceiling of 
a Class B or Class C airspace area designated for an 
airport or 10,000 feet MSL, whichever is lower. 

c.  Charts. 

Class B airspace is charted on 

Sectional Charts, IFR En Route Low Altitude, and 
Terminal Area Charts. 

d.  Flight Procedures. 

1.  Flights. 

Aircraft within Class B airspace are 

required to operate in accordance with current IFR 
procedures. A clearance for a visual approach to a 
primary airport is not authorization for turbine

 

powered airplanes to operate below the designated 
floors of the Class B airspace. 

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
