Flight rules "airspace clissifiaction"

Introduction:

  • The National Airspace System is the network of United States airspace, air navigation facilities, airports, regulations, procedures, technical information, manpower, and material shared jointly between the Federal Aviation Administration (FAA) and the military
 In the united states of America there are different Airspace according to what published in FAR Part 71 & 91; AIM Ch 3
·         Categories of Airspace:
·       They are divided into two category;
1.       Regulatory (A, B, C, D, E, Restricted, and Prohibited)
2.       Non-regulatory (MOAs, Warning Areas, Alert Areas, and Controlled Firing Areas). 
Within in these two categories there are four types:
·       Controlled – Airspace that has air traffic control service provided in accordance with the airspace classification for A, B, C, D, E
·       Uncontrolled – Airspace that is under FAA jurisdiction that is not Class A, B, C, D, or E, and which no air traffic control services are provided

·       Special Use
    ·       Other

· Airspace Classification - Dimensions and Requirements



i.            Class A: 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.  Unless otherwise authorized, all persons must operate their aircraft under IFR.  (FAR 71.33, 91.167 – 91.193)
ii.            Class B: 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."  Requirements for VFR Operations:
1.       Two-way radio
2.       Hold at least a Private Pilot Certificate
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.

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.
7.       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.
a.       VFR aircraft are separated from all VFR/IFR aircraft which weigh 19,000 pounds or less by a minimum of:
i.         Target resolution, or
ii.        500 feet vertical separation, or
iii.      Visual separation.
b.       VFR aircraft are separated from all VFR/IFR aircraft which weigh more than 19,000 and turbojets by no less than:
i.         1 ½ miles lateral separation, or
ii.        500 feet vertical separation, or
iii.      Visual separation.
iii.  Class C: 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.  Requirements include:
1.       No specific pilot certification is required
2.       Unless otherwise authorized by ATC, an operable radar beacon transponder with automatic altitude reporting equipment.
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 (communications are established when the controller responds with the aircraft’s callsign).
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).
6.       Air Traffic Services: When two-way radio communications and radar contact are established, all participating VFR aircraft are:
a.       Sequenced to the primary airport.
b.       Provided Class C services within the Class C airspace and the outer area.
c.        Provided basic radar services beyond the outer area on a workload permitting basis.  This can be terminated by the controller if workload dictates.
7.       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:
a.       Visual separation.
b.       500 feet vertical; except when operating beneath a heavy jet.
c.        Target resolution.
8.       Secondary Airports
a.       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.
b.       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.
c.        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
iv.  Class D: 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.  Requirements include:
1.       No specific pilot certification required.
2.       Equipment: 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.
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).
6.       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].
7.       Arrival extensions for instrument approach procedures may be Class D or Class E airspace.  Generally, 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.
8.       No separation services are provided to VFR aircraft.
v.   Class E: 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.  Requirements include:
1.       No specific certification required.
2.       No specific equipment required by the airspace.
3.       Arrival or Through Flight Entry Requirements: No specific requirements.
4.       Charts: Class E airspace below 14,500 feet MSL is charted on Sectional, Terminal, and IFR Enroute Low Altitude charts.
5.       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.
6.       Types of Class E Airspace:
a.       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.
b.       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.
c.        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.
d.       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.
e.        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.
f.        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.
g.        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.
7.       No separation services are provided to VFR aircraft.
i.            viClass G: Class G Airspace (uncontrolled) is that portion of airspace that has not bee n designated as Class A, Class B, Class C, Class D, or Class E airspace.  
1.       VFR requirements: Rules governing VFR flight have been adopted to assist the pilot in meeting the responsibility to see and avoid other aircraft.  Minimum flight visibility and distance from clouds required for VFR flight are contained in FAR 91.155.
2.       IFR Requirements: Title 14 CFR specifies the pilot and aircraft equipment requirements for IFR flight.  Pilots are reminded that in addition to altitude or flight level requirements, 14 CFR Section 91.177 includes a requirement to remain at least 1,000 feet   (2,000 feet in designated mountainous terrain) above the highest obstacle within a horizontal distance of 4 nautical miles from the course to be flown.  IFR Altitudes:

IFR Altitudes
Class G Airspace
If your magnetic course (ground track) is:
And you are below 18,000 feet MSL, fly:
0° to 179°
Odd thousands MSL, (3,000; 5,000; 7,000, etc.)
180° to 359°
Even thousands MSL, (2,000; 4,000; 6,000, etc.)

·       Special Use Airspace:
i.         General :
1.       Special use airspace consists of that airspace wherein activities must be confined because of their nature, or wherein limitations are imposed upon aircraft operations that are not a part of those activities, or both.  Except for controlled firing areas, special use airspace areas are depicted on aeronautical charts.
2.       Prohibited and restricted areas are regulatory special use airspace and are established in 14 CFR Part 73 through the rulemaking process.
3.       Warning areas, military operations areas (MOAs), alert areas, and controlled firing areas (CFAs) are nonregulatory special use airspace.
4.       Special use airspace descriptions (except CFAs) are contained in FAA Order JO 7400.8, Special Use Airspace.
5.       Special use airspace (except CFAs) are charted on IFR or visual charts and include the hours of operation, altitudes, and the controlling agency.
ii.  Prohibited Areas
1.       Prohibited areas contain airspace of defined dimensions identified by an area on the surface of the earth within which the flight of aircraft is prohibited.  Such areas are established for security or other reasons associated with the national welfare.  These areas are published in the Federal Register and are depicted on aeronautical charts.
iii.      Restricted Areas
1.       Restricted areas contain airspace identified by an area on the surface of the earth within which the flight of aircraft, while not wholly prohibited, is subject to restrictions.  Activities within these areas must be confined because of their nature or limitations imposed upon aircraft operations that are not a part of those activities or both.  Restricted areas denote the existence of unusual, often invisible, hazards to aircraft such as artillery firing, aerial gunnery, or guided missiles.  Penetration of restricted areas without authorization from the using or controlling agency may be extremely hazardous to the aircraft and its occupants.  Restricted areas are published in the Federal Register and constitute 14 CFR Part 73.
2.       ATC facilities apply the following procedures when aircraft are operating on an IFR clearance (including those cleared by ATC to maintain VFR-on-top) via a route which lies within joint-use restricted airspace.
a.       If the restricted area is not active and has been released to the controlling agency (FAA), the ATC facility will allow the aircraft to operate in the restricted airspace without issuing specific clearance for it to do so.
b.       If the restricted area is active and has not been released to the controlling agency (FAA), the ATC facility will issue a clearance which will ensure the aircraft avoids the restricted airspace unless it is on an approved altitude reservation mission or has obtained its own permission to operate in the airspace and so informs the controlling facility.

NOTE
The above apply only to joint-use restricted airspace and not to prohibited and nonjoint-use airspace.  For the latter categories, the ATC facility will issue a clearance so the aircraft will avoid the restricted airspace unless it is on an approved altitude reservation mission or has obtained its own permission to operate in the airspace and so informs the controlling facility.

c.        Restricted airspace is depicted on the en route chart appropriate for use at the altitude or flight level being flown.  For joint-use restricted areas, the name of the controlling agency is shown on these charts.  For all prohibited areas and nonjoint-use restricted areas, unless otherwise requested by the using agency, the phrase "NO A/G" is shown.
iv.  Warning Areas
1.       A warning area is airspace of defined dimensions, extending from three nautical miles outward from the coast of the U.S. that contains activity that may be hazardous to nonparticipating aircraft.  The purpose of such warning areas is to warn nonparticipating pilots of the potential danger.  A warning area may be located over domestic or international waters or both.
v.  Military Operations Areas
1.       MOAs consist of airspace of defined vertical and lateral limits established for the purpose of separating certain military training activities from IFR traffic.  Whenever a MOA is being used, nonparticipating IFR traffic may be cleared through a MOA if IFR separation can be provided by ATC.  Otherwise, ATC will reroute or restrict nonparticipating IFR traffic.
2.       Examples of activities conducted in MOAs include, but are not limited to: air combat tactics, air intercepts, aerobatics, formation training, and low-altitude tactics.  Military pilots flying in an active MOA are exempted from the provisions of 14 CFR Section 91.303(c) and (d) which prohibits aerobatic flight within Class D and Class E surface areas, and within Federal airways.  Additionally, the Department of Defense has been issued an authorization to operate aircraft at indicated airspeeds in excess of 250 knots below 10,000 feet MSL within active MOAs.
3.       Pilots operating under VFR should exercise extreme caution while flying within a MOA when military activity is being conducted.  The activity status (active/inactive) of MOAs may change frequently.  Therefore, pilots should contact any FSS within 100 miles of the area to obtain accurate real-time information concerning the MOA hours of operation.  Prior to entering an active MOA, pilots should contact the controlling agency for traffic advisories.
4.       MOAs are depicted on sectional, VFR Terminal Area, and Enroute Low Altitude charts.




vi.  Alert Areas
1.       Alert areas are depicted on aeronautical charts to inform nonparticipating pilots of areas that may contain a high volume of pilot training or an unusual type of aerial activity.  Pilots should be particularly alert when flying in these areas.  All activity within an alert area shall be conducted in accordance with CFRs, without waiver, and pilots of participating aircraft as well as pilots transiting the area shall be equally responsible for collision avoidance.
vii.    Controlled Firing Areas
1.       CFAs contain activities which, if not conducted in a controlled environment, could be hazardous to nonparticipating aircraft.  The distinguishing feature of the CFA, as compared to other special use airspace, is that its activities are suspended immediately when spotter aircraft, radar, or ground lookout positions indicate an aircraft might be approaching the area.  There is no need to chart CFAs since they do not cause a nonparticipating aircraft to change its flight path.
·         Other:
i.         VOR Airways “Victor” - extend from 1200 feet AGL to, but not including, 18,000 feet MSL 4 NM either side of centerline, within 51 NM of the facility.  Beyond 51 NM the 4.5° accuracy factor determines the width of the airways/routes (approximately 2 NM in total width every 13 NM).  Airways are even numbered for East/West and odd for North/South (FIH Sec B)
ii.        Jet Routes - Class A designated by “J” extend from 18,000 feet MSL to FL 450 no width.  Upper limit is established to prevent interference between stations with similar frequencies.
iii.      Military Training Routes
1.       MTRs are mutually developed for use by the military for the purpose of conducting low-altitude, high-speed training.  The routes above 1,500 feet AGL are developed to be flown, to the maximum extent possible, under IFR.  The routes at 1,500 feet AGL and below are generally developed to be flown under VFR.
2.       Generally, MTRs are established below 10,000 feet MSL for operations at speeds in excess of 250 knots.  However, route segments may be defined at higher altitudes for purposes of route continuity.  For example, route segments may be defined for descent, climbout, and mountainous terrain.  There are IFR and VFR routes as follows:
a.       IFR Military Training Routes (IR):  Operations on these routes are conducted in accordance with IFR regardless of weather conditions.
b.       VFR Military Training Routes (VR):  Operations on these routes are conducted in accordance with VFR except flight visibility shall be 5 miles or more; and flights shall not be conducted below a ceiling of less than 3,000 feet AGL.
3.       Military training routes will be identified and charted as follows:
a.       Route identification.
i.         MTRs with no segment above 1,500 feet AGL shall be identified by four number characters; e.g., IR1206, VR1207.
ii.        MTRs that include one or more segments above 1,500 feet AGL shall be identified by three number characters; e.g., IR206, VR207.
iii.      Alternate IR/VR routes or route segments are identified by using the basic/principal route designation followed by a letter suffix, e.g., IR008A, VR1007B, etc.
b.       Route charting.
i.         IFR Low Altitude En Route Chart.  This chart will depict all IR routes and all VR routes that accommodate operations above 1,500 feet AGL.
ii.        VFR Sectional Charts.  These charts will depict military training activities such as IR, VR, MOA, Restricted Area, Warning Area, and Alert Area information.
iii.      Area Planning (AP/1B) Chart (DOD Flight Information Publication-FLIP).  This chart is published by the DOD primarily for military users and contains detailed information on both IR and VR routes.
iv.      Temporary Flight Restrictions
v.       Parachute Jump Areas
vi.      VFR Routes:
1.       Published VFR routes for transitioning around, under and through complex airspace such as Class B airspace were developed through a number of FAA and industry initiatives.  All of the following terms, i.e., "VFR Flyway" "VFR Corridor" and "Class B Airspace VFR Transition Route" have been used when referring to the same or different types of routes or airspace.  The following paragraphs identify and clarify the functionality of each type of route, and specify where and when an ATC clearance is required.
a.       VFR Flyways: VFR Flyways and their associated Flyway Planning Charts were developed from the recommendations of a National Airspace Review Task Group.  A VFR Flyway is defined as a general flight path not defined as a specific course, for use by pilots in planning flights into, out of, through, or near complex terminal airspace to avoid Class B airspace.  An ATC clearance is NOT required to fly these routes.
b.       VFR Corridors: The design of a few of the first Class B airspace areas provided a corridor for the passage of uncontrolled traffic.  A VFR corridor is defined as airspace through Class B airspace, with defined vertical and lateral boundaries, in which aircraft may operate without an ATC clearance or communication with air traffic control.  These corridors are, in effect, a "hole" through Class B airspace.  A classic example would be the corridor through the Los Angeles Class B airspace, which has been subsequently changed to Special Flight Rules airspace (SFR).  A corridor is surrounded on all sides by Class B airspace and does not extend down to the surface like a VFR Flyway.  Because of their finite lateral and vertical limits, and the volume of VFR traffic using a corridor, extreme caution and vigilance must be exercised.
c.  Class B Airspace VFR Transition Routes: To accommodate VFR traffic through certain Class B airspace, such as Seattle, Phoenix and Los Angeles, Class B Airspace VFR Transition Routes were developed.  A Class B Airspace VFR Transition Route is defined as a specific flight course depicted on a TAC for transiting a specific Class B airspace.  These routes include specific ATC assigned altitudes, and pilots must obtain an ATC clearance prior to entering Class B airspace on the route.  These routes, as depicted in FIG 3-5-3, are designed to show the pilot where to position the aircraft outside of, or clear of, the Class B airspace where an ATC clearance can normally be expected with minimal or no delay.  Until ATC authorization is received, pilots must remain clear of Class B airspace.  On initial contact, pilots should advise ATC of their position, altitude, route name desired, and direction of flight.  After a clearance is received, pilots must fly the route as depicted and, most importantly, adhere to ATC instructions.
vii.    Terminal Radar Service Area (TRSA)
1.       TRSAs were originally established as part of the Terminal Radar Program at selected airports.  TRSAs were never controlled airspace from a regulatory standpoint because the establishment of TRSAs was never subject to the rulemaking process; consequently, TRSAs are not contained in 14 CFR Part 71 nor are there any TRSA operating rules in 14 CFR Part 91.  Part of the Airport Radar Service Area (ARSA) program was to eventually replace all TRSAs.  However, the ARSA requirements became relatively stringent and it was subsequently decided that TRSAs would have to meet ARSA criteria before they would be converted.  TRSAs do not fit into any of the U.S. airspace classes; therefore, they will continue to be non-Part 71 airspace areas where participating pilots can receive additional radar services which have been redefined as TRSA Service.
2.       The primary airport(s) within the TRSA become(s) Class D airspace.  The remaining portion of the TRSA overlies other controlled airspace which is normally Class E airspace beginning at 700 or 1,200 feet and established to transition to/from the en route/terminal environment.
3.       Pilots operating under VFR are encouraged to contact the radar approach control and avail themselves of the TRSA Services.  However, participation is voluntary on the part of the pilot.  Military personnel shall request TRSA Services
4.       TRSAs are depicted on VFR sectional and terminal area charts with a solid black line and altitudes for each segment.  The Class D portion is charted with a blue segmented line.
viii.   National Security Areas: National Security Areas consist of airspace of defined vertical and lateral dimensions established at locations where there is a requirement for increased security and safety of ground facilities.  Pilots are requested to voluntarily avoid flying through the depicted NSA.  When it is necessary to provide a greater level of security and safety, flight in NSAs may be temporarily prohibited by regulation under the provisions of 14 CFR Section 99.7.  Regulatory prohibitions will be issued by System Operations, System Operations Airspace and AIM Office,
