3-2-1. General
a. Controlled Airspace. A generic term that
covers the different classification of airspace
(Class A, Class B, Class C, Class D, and Class E
airspace) and defined dimensions within which air
traffic control service is provided to IFR flights and
to VFR flights in accordance with the airspace
classification. (See
FIG 3-2-1.)
b. IFR Requirements. IFR operations in any
class of controlled airspace requires that a pilot must
file an IFR flight plan and receive an appropriate ATC
clearance.
c. IFR Separation. Standard IFR separation is
provided to all aircraft operating under IFR in
controlled airspace.
d. VFR Requirements. It is the responsibility of
the pilot to insure that ATC clearance or radio
communication requirements are met prior to entry
into Class B, Class C, or Class D airspace. The pilot
retains this responsibility when receiving ATC radar
advisories. (See 14 CFR Part 91.)
e. Traffic Advisories. Traffic advisories will be
provided to all aircraft as the controller's work
situation permits.
f. Safety Alerts. Safety Alerts are mandatory
services and are provided to ALL aircraft. There are
two types of Safety Alerts:
1. Terrain/Obstruction Alert. A Terrain/Obstruction Alert is issued when, in the controller's
judgment, an aircraft's altitude places it in unsafe
proximity to terrain and/or obstructions; and
2. Aircraft Conflict/Mode C Intruder Alert.
An Aircraft Conflict/Mode C Intruder Alert is issued
if the controller observes another aircraft which
places it in an unsafe proximity. When feasible, the
controller will offer the pilot an alternative course of
action.
g. Ultralight Vehicles. No person may operate an
ultralight vehicle within Class A, Class B, Class C, or
Class D airspace or within the lateral boundaries of
the surface area of Class E airspace designated for an
airport unless that person has prior authorization from
the ATC facility having jurisdiction over that
airspace. (See 14 CFR Part 103.)
h. Unmanned Free Balloons. Unless otherwise
authorized by ATC, no person may operate an
unmanned free balloon below 2,000 feet above the
surface within the lateral boundaries of Class B,
Class C, Class D, or Class E airspace designated for
an airport. (See 14 CFR Part 101.)
i. Parachute Jumps. No person may make a
parachute jump, and no pilot-in-command may
allow a parachute jump to be made from that aircraft,
in or into Class A, Class B, Class C, or Class D
airspace without, or in violation of, the terms of an
ATC authorization issued by the ATC facility having
jurisdiction over the airspace. (See 14 CFR Part 105.)
3-2-2. Class A Airspace
a. Definition. Generally, that airspace from
18,000 feet MSL up to and including FL 600,
including the airspace overlying the waters within
12 nautical miles of the coast of the 48 contiguous
States and Alaska; and designated international
airspace beyond 12 nautical miles of the coast of the
48 contiguous States and Alaska within areas of
domestic radio navigational signal or ATC radar
coverage, and within which domestic procedures are
applied.
b. Operating Rules and Pilot/Equipment
Requirements. Unless otherwise authorized, all
persons must operate their aircraft under IFR. (See
14 CFR Section 71.33 and 14 CFR Section 91.167
through 14 CFR Section 91.193.)
c. Charts. Class A airspace is not specifically
charted.
3-2-3. Class B Airspace
a. Definition. Generally, that airspace from the
surface to 10,000 feet MSL surrounding the nation's
busiest airports in terms of IFR operations or
passenger enplanements. The configuration of each
Class B airspace area is individually tailored and
consists of a surface area and two or more layers
(some Class B airspace areas resemble upside-down
wedding cakes), and is designed to contain all
published instrument procedures once an aircraft
enters the airspace. An ATC clearance is required for
all aircraft to operate in the area, and all aircraft that
are so cleared receive separation services within the
airspace. The cloud clearance requirement for VFR
operations is "clear of clouds."
b. Operating Rules and Pilot/Equipment
Requirements for VFR Operations. Regardless of
weather conditions, an ATC clearance is required
prior to operating within Class B airspace. Pilots
should not request a clearance to operate within
Class B airspace unless the requirements of 14 CFR
Section 91.215 and 14 CFR Section 91.131 are met.
Included among these requirements are:
1. Unless otherwise authorized by ATC, aircraft
must be equipped with an operable two-way radio
capable of communicating with ATC on appropriate
frequencies for that Class B airspace.
2. No person may take off or land a civil aircraft
at the following primary airports within Class B
airspace unless the pilot-in-command holds at least
a private pilot certificate:
(a) Andrews Air Force Base, MD
(b) Atlanta Hartsfield Airport, GA
(c) Boston Logan Airport, MA
(d) Chicago O'Hare Intl. Airport, IL
(e) Dallas/Fort Worth Intl. Airport, TX
(f) Los Angeles Intl. Airport, CA
(g) Miami Intl. Airport, FL
(h) Newark Intl. Airport, NJ
(i) New York Kennedy Airport, NY
(j) New York La Guardia Airport, NY
(k) Ronald Reagan Washington National
Airport, DC
(l) San Francisco Intl. Airport, CA
3. No person may take off or land a civil aircraft
at an airport within Class B airspace or operate a civil
aircraft within Class B airspace unless:
(a) The pilot-in-command holds at least a
private pilot certificate; or
(b) The aircraft is operated by a student pilot
or recreational pilot who seeks private pilot
certification and has met the requirements of 14 CFR
Section 61.95.
4. Unless otherwise authorized by ATC, each
person operating a large turbine engine-powered
airplane to or from a primary airport shall 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; 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 equipment.
NOTE-
ATC may, upon notification, immediately authorize a
deviation from the altitude reporting equipment requirement; 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.
REFERENCE-
AIM, Transponder Operation, Paragraph
4-1-19.
6. Mode C Veil. The airspace within 30 nautical 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 automatic pressure altitude reporting
equipment having Mode C capability.
However, an aircraft that was not originally
certificated with an engine-driven electrical system
or which has 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
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.
REFERENCE-
AIM, Terminal Radar Services for VFR Aircraft, Paragraph
4-1-17.
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 above the surface 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.
3-2-4. Class C Airspace
a. Definition. Generally, that airspace from the
surface to 4,000 feet above the airport elevation
(charted in MSL) surrounding those airports that have
an operational control tower, are serviced by a radar
approach control, and that have a certain number of
IFR operations or passenger enplanements. Although
the configuration of each Class C airspace area is
individually tailored, the airspace usually consists of
a 5 NM radius core surface area that extends from the
surface up to 4,000 feet above the airport elevation,
and a 10 NM radius shelf area that extends no lower
than 1,200 feet up to 4,000 feet above the airport
elevation.
b. Charts. Class C airspace is charted on
Sectional Charts, IFR En Route Low Altitude, and
Terminal Area Charts where appropriate.
c. Operating Rules and Pilot/Equipment
Requirements:
1. Pilot Certification. No specific certification required.
2. Equipment.
(a) Two-way radio; and
(b) Unless otherwise authorized by ATC, an
operable radar beacon transponder with automatic
altitude reporting equipment.
NOTE-
See paragraph
4-1-19, Transponder Operation,
subparagraph
f2(c) for Mode C
transponder requirements for operating above Class C
airspace.
3. Arrival or Through Flight Entry Requirements. Two-way radio communication must be
established with the ATC facility providing ATC
services prior to entry and thereafter maintain those
communications while in Class C airspace. Pilots of
arriving aircraft should contact the Class C airspace
ATC facility on the publicized frequency and give
their position, altitude, radar beacon code, destination, and request Class C service. Radio contact
should be initiated far enough from the Class C
airspace boundary to preclude entering Class C
airspace before two-way radio communications are
established.
NOTE-
1. If the controller responds to a radio call with, "(aircraft
callsign) standby," radio communications have been
established and the pilot can enter the Class C airspace.
2. If workload or traffic conditions prevent immediate
provision of Class C services, the controller will inform the
pilot to remain outside the Class C airspace until
conditions permit the services to be provided.
3. It is important to understand that if the controller
responds to the initial radio call without using the aircraft
identification, radio communications have not been
established and the pilot may not enter the Class C
airspace.
4. Though not requiring regulatory action, Class C
airspace areas have a procedural Outer Area. Normally
this area is 20 NM from the primary Class C airspace
airport. Its vertical limit extends from the lower limits of
radio/radar coverage up to the ceiling of the approach
control's delegated airspace, excluding the Class C
airspace itself, and other airspace as appropriate. (This
outer area is not charted.)
5. Pilots approaching an airport with Class C service
should be aware that if they descend below the base altitude
of the 5 to 10 mile shelf during an instrument or visual
approach, they may encounter nontransponder, VFR
aircraft.
EXAMPLE-
1. [Aircraft callsign] "remain outside the Class Charlie
airspace and standby."
2. "Aircraft calling Dulles approach control, standby."
4. Departures from:
(a) A primary or satellite airport with an
operating control tower. Two-way radio communications must be established and maintained with the
control tower, and thereafter as instructed by ATC
while operating in Class C airspace.
(b) A satellite airport without an operating
control tower. Two-way radio communications must
be established as soon as practicable after departing
with the ATC facility having jurisdiction over the
Class C airspace.
5. Aircraft Speed. Unless otherwise authorized or required by ATC, no person may operate an
aircraft at or below 2,500 feet above the surface
within 4 nautical miles of the primary airport of a
Class C airspace area at an indicated airspeed of more
than 200 knots (230 mph).
d. Air Traffic Services. When two-way radio
communications and radar contact are established, all
participating VFR aircraft are:
1. Sequenced to the primary airport.
2. Provided Class C services within the Class C
airspace and the outer area.
3. Provided basic radar services beyond the
outer area on a workload permitting basis. This can be
terminated by the controller if workload dictates.
e. Aircraft Separation. Separation is provided
within the Class C airspace and the outer area after
two-way radio communications and radar contact are
established. VFR aircraft are separated from IFR
aircraft within the Class C airspace by any of the
following:
1. Visual separation.
2. 500 feet vertical; except when operating
beneath a heavy jet.
3. Target resolution.
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 CENRAP
is in use.
3. Pilot participation is voluntary within the outer area
and can be discontinued, within the outer area, at the pilot's
request. Class C services will be provided in the outer area
unless the pilot requests termination of the service.
4. Some facilities provide Class C services only during
published hours. At other times, terminal IFR radar service
will be provided. It is important to note that the
communications and transponder requirements are
dependent of the class of airspace established outside of the
published hours.
f. Secondary Airports
1. In some locations Class C airspace may
overlie the Class D surface area of a secondary
airport. In order to allow that control tower to provide
service to aircraft, portions of the overlapping
Class C airspace may be procedurally excluded when
the secondary airport tower is in operation. Aircraft
operating in these procedurally excluded areas will
only be provided airport traffic control services when
in communication with the secondary airport tower.
2. Aircraft proceeding inbound to a satellite
airport will be terminated at a sufficient distance to
allow time to change to the appropriate tower or
advisory frequency. Class C services to these aircraft
will be discontinued when the aircraft is instructed to
contact the tower or change to advisory frequency.
3. Aircraft departing secondary controlled
airports will not receive Class C services until they
have been radar identified and two-way communications have been established with the Class C airspace
facility.
4. 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.
(See TBL 3-2-1.)
Class C Airspace Areas by State
These states currently have designated Class C
airspace areas that are depicted on sectional charts.
Pilots should consult current sectional charts and
NOTAMs for the latest information on services
available. Pilots should be aware that some Class C
airspace underlies or is adjacent to Class B airspace.

3-2-5. Class D Airspace
a. Definition. Generally, that airspace from the
surface to 2,500 feet above the airport elevation
(charted in MSL) surrounding those airports that have
an operational control tower. The configuration of
each Class D airspace area is individually tailored and
when instrument procedures are published, the
airspace will normally be designed to contain the
procedures.
b. Operating Rules and Pilot/Equipment
Requirements:
1. Pilot Certification. No specific certification required.
2. Equipment. Unless otherwise authorized
by ATC, an operable two-way radio is required.
3. Arrival or Through Flight Entry
Requirements. Two-way radio communication
must be established with the ATC facility providing
ATC services prior to entry and thereafter maintain
those communications while in the Class D airspace.
Pilots of arriving aircraft should contact the control
tower on the publicized frequency and give their
position, altitude, destination, and any request(s).
Radio contact should be initiated far enough from the
Class D airspace boundary to preclude entering the
Class D airspace before two-way radio communications are established.
NOTE-
1. If the controller responds to a radio call with, "[aircraft
callsign] standby," radio communications have been
established and the pilot can enter the Class D airspace.
2. If workload or traffic conditions prevent immediate
entry into Class D airspace, the controller will inform the
pilot to remain outside the Class D airspace until
conditions permit entry.
EXAMPLE-
1. "[Aircraft callsign] remain outside the Class Delta
airspace and standby."
It is important to understand that if the controller responds
to the initial radio call without using the aircraft callsign,
radio communications have not been established and the
pilot may not enter the Class D airspace.
2. "Aircraft calling Manassas tower standby."
At those airports where the control tower does not operate
24 hours a day, the operating hours of the tower will be
listed on the appropriate charts and in the A/FD. During
the hours the tower is not in operation, the Class E surface
area rules or a combination of Class E rules to 700 feet
above ground level and Class G rules to the surface will
become applicable. Check the A/FD for specifics.
4. Departures from:
(a) A primary or satellite airport with an
operating control tower. Two-way radio communications must be established and maintained with the
control tower, and thereafter as instructed by ATC
while operating in the Class D airspace.
(b) A satellite airport without an operating
control tower. Two-way radio communications must
be established as soon as practicable after departing
with the ATC facility having jurisdiction over the
Class D airspace as soon as practicable after
departing.
5. Aircraft Speed. Unless otherwise authorized or required by ATC, no person may operate an
aircraft at or below 2,500 feet above the surface
within 4 nautical miles of the primary airport of a
Class D airspace area at an indicated airspeed of more
than 200 knots (230 mph).
c. Class D airspace areas are depicted on Sectional
and Terminal charts with blue segmented lines, and
on IFR En Route Lows with a boxed [D].
d. Arrival extensions for instrument approach
procedures may be Class D or Class E airspace. As a
general rule, if all extensions are 2 miles or less, they
remain part of the Class D surface area. However, if
any one extension is greater than 2 miles, then all
extensions become Class E.
e. Separation for VFR Aircraft. No separation
services are provided to VFR aircraft.
3-2-6. Class E Airspace
a. Definition. Generally, if the airspace is not
Class A, Class B, Class C, or Class D, and it is
controlled airspace, it is Class E airspace.
b. Operating Rules and Pilot/Equipment
Requirements:
1. Pilot Certification. No specific certification required.
2. Equipment. No specific equipment
required by the airspace.
3. Arrival or Through Flight Entry Requirements. No specific requirements.
c. Charts. Class E airspace below 14,500 feet
MSL is charted on Sectional, Terminal, and IFR
Enroute Low Altitude charts.
d. Vertical limits. Except for 18,000 feet MSL,
Class E airspace has no defined vertical limit but
rather it extends upward from either the surface or a
designated altitude to the overlying or adjacent
controlled airspace.
e. Types of Class E Airspace:
1. Surface area designated for an airport. When designated as a surface area for an
airport, the airspace will be configured to contain all
instrument procedures.
2. Extension to a surface area. There are
Class E airspace areas that serve as extensions to
Class B, Class C, and Class D surface areas
designated for an airport. Such airspace provides
controlled airspace to contain standard instrument
approach procedures without imposing a communications requirement on pilots operating under VFR.
3. Airspace used for transition. There are
Class E airspace areas beginning at either 700 or
1,200 feet AGL used to transition to/from the
terminal or en route environment.
4. En Route Domestic Areas. There are
Class E airspace areas that extend upward from a
specified altitude and are en route domestic airspace
areas that provide controlled airspace in those areas
where there is a requirement to provide IFR en route
ATC services but the Federal airway system is
inadequate.
5. Federal Airways. The Federal airways are
Class E airspace areas and, unless otherwise
specified, extend upward from 1,200 feet to, but not
including, 18,000 feet MSL. The colored airways are
green, red, amber, and blue. The VOR airways are
classified as Domestic, Alaskan, and Hawaiian.
6. Offshore Airspace Areas. There are
Class E airspace areas that extend upward from a
specified altitude to, but not including, 18,000 feet
MSL and are designated as offshore airspace areas.
These areas provide controlled airspace beyond
12 miles from the coast of the U.S. in those areas
where there is a requirement to provide IFR en route
ATC services and within which the U.S. is applying
domestic procedures.
7. Unless designated at a lower altitude, Class E
airspace begins at 14,500 feet MSL to, but not
including, 18,000 feet MSL overlying: the 48 contiguous States including the waters within 12 miles from
the coast of the 48 contiguous States; the District of
Columbia; Alaska, including the waters within
12 miles from the coast of Alaska, and that airspace
above FL 600; excluding the Alaska peninsula west
of long. 160°00'00''W, and the airspace below
1,500 feet above the surface of the earth unless
specifically so designated.
f. Separation for VFR Aircraft. No separation
services are provided to VFR aircraft.
