1 VFR AERONAUTICAL CHARTS

EXPLANATION OF VFR TERMS AND SYMBOLS

The discussions and examples in this section are based on the Sectional Aeronautical Chart (Sectional). Sec-tionals include the most current data and are at a scale (1:500,000) most beneficial to pilots flying under Visual FlightRules. A pilot should have little difficulty in reading these charts which are, in many respects, similar to automobileroad maps. Each chart is named for a major city within its area of coverage.

The chart legend lists various aeronautical symbols as well as information concerning terrain and contourelevations. You may identify aeronautical, topographical, and obstruction symbols (such as radio and television tow-ers) by referring to the legend. Many landmarks which can be easily recognized from the air, such as stadiums,pumping stations, refineries, etc., are identified by brief descriptions adjacent to small black squares marking their

exact locations . Oil wells are shown by small open circles . Water, oil and gas tanks are shown by smal

black circles and labeled accordingly, if known. The scale of an item may be increased to make it easier toread on the chart.

NACO charts are prepared in accordance with specifications of the Interagency Air Cartographic Committee(IACC) and are approved by representatives of the Federal Aviation Administration (FAA) and the Department ofDefense (DoD).

TERRAIN AND OBSTRUCTIONS

The elevation and configuration of the Earth'ssurface are certainly of prime importance to pilots. Car-tographers devote a great deal of attention to showingrelief and obstruction data in a clear and concise manner.Five different techniques are used: contour lines, shadedrelief, color tints, obstruction symbols, and MaximumElevation Figures. (MEF)

1. Contour lines are lines con-necting points on the Earth of equalelevation. On Sectionals, basic con-tours are spaced at 500' intervals.Intermediate contours may also be shown at 250' inter-vals in moderately level or gently rolling areas. Occasion-ally, auxiliary contours at 50, 100, 125, or 150' intervalsmay be used to portray smaller relief features in areas ofrelatively low relief. The pattern of these lines and theirspacing gives the pilot a visual concept of the terrain.Widely spaced contours represent gentle slopes, whileclosely spaced contours represent steep slopes.

2. Shaded relief is a depic-tion of how the terrain mightappear from the air. The cartogra-pher shades the areas that wouldappear in shadow if illuminated bya light from the northwest. Studieshave indicated that our visual per-ception has been conditioned to this view.

3. Color tints are used todepict bands of elevation. These col-ors range from light green for thelowest elevations to brown for thehigher elevations.

4. Obstruction symbols areused to depict man-made vertical features that mayaffect the National Airspace System. NACO maintains afile of over 109,000 obstacles in the United States, Can-ada, the Caribbean and Mexico. Each obstacle is evalu-ated by cartographers before it is added to the visuacharts. When the position or elevation of an obstacle isunverified, it is marked UC (under construction orreported but not verified).

The data in the Digital Obstacle File (DOF) is col-lected and disseminated as part of NACOs responsibilityfor depicting the National Airspace System.

Source data on terrain and obstructions is some-times not complete or accurate enough for use in aero-nautical publications; for example, a reported obstructionmay be submitted with insufficient detail for determiningthe obstruction's position and elevation. Such cases areidentified by NACO and investigated by the FAA FlightEdit program.

The FAA Flight Edit crew conducts data verifica-tion missions, visually verifying cultural and topographicfeatures and reviewing all obstacle data. This reviewincludes checking for obstructions that may have beenconstructed, altered, or dismantled without proper notifi-cation. Unverified obstacles are subsequently photo-

graphed and the position and elevation are determinedphotogrammetrically.

Generally, only man-made structures extendingmore than 200' above ground level (AGL) are charted.

Objects 200' or less are charted only if they are consid-ered hazardous obstructions; for example, an obstruc-tion is much higher than the surrounding terrain or verynear an airport. Examples of features considered hazard-ous obstacles to low level flight are antennas, tanks, fac-tories, lookout towers, and smoke-stacks.

Obstacles less than 1000' AGL are shown by the

symbol . Obstacles 1000' and higher AGL are

shown by the symbol . Man-made features which areused by FAA Air Traffic Control as checkpoints may berepresented with pictorial symbols shown in black with

the required elevation data in blue.

The elevation of the top of theobstacle above mean sea level (MSL) andthe height of the structure AGL are shownwhen known or when they can be reliablydetermined by the cartographer. The

AGL height is shown in parenthesesbelow the MSL elevation. In extremely congested areasthe AGL values may be omitted to avoid confusion.

Obstacles are portrayed wherever possible. Butsince legibility would be impaired if all obstacles withincity complexes or within high density groups of obstacles

were portrayed, only the highest obstacle in an area is

shown using , the group obstacle symbol.

Obstacles under construction are indicated by

the letters immediately adjacent to the symbol. If

available, the AGL height of the obstruction is shown in

parentheses; for example, . Obstacles with high-in tens i t y s t robe l i gh t i ng sys tems a re shown

as:

5. The Maximum Elevation Figure (MEF) repre-sents the highest elevation, including terrain and othevertical obstacles (towers, trees, etc.), within a quadrant

A quadrant on Sectionals is the area bounded by tickedlines dividing each 30 minutes of latitude and each 30minutes of longitude. MEF figures are depicted to thenearest 100' value. The last two digits of the number arenot shown. In this example the MEF represents 12,500'

MEFs are shown over land masses as well as over openwater areas containing man-made obstacles such as oirigs.

In the determination of MEFs, extreme care isexercised to calculate the values based on the existing

elevation data shown on source material. Cartographersuse the following procedure to calculate MEFs:

When a man-made obstacle is more than 200above the highest terrain within the quadrant:

1. Determine the elevation of the top of theobstacle above MSL.

2. Add the possible vertical error of the sourcematerial to the above figure (100' or 1/2 con-tour interval when interval on source exceeds200'. U.S. Geological Survey QuadrangleMaps with contour intervals as small as 10are normally used).

3. Round the resultant figure up to the nexthigher hundred foot level.

Example: Elevation of obstacle top (MSL) = 2424Possible vertical error + 100

equals 2524Raise to the following 100 foot level 2600

Maximum Elevation Figure

When a natural terrain feature or natural vertical obstacle(e.g. a tree) is the highest feature within the quadrangle.:

1. Determine the elevation of the feature.

2. Add the possible vertical error of the sourceto the above figure (100' or 1/2 the contourinterval when interval on source exceeds200').

3. Add a 200' allowance for natural or man-made obstacles which are not portrayedbecause they are below the minimum heightat which the chart specifications require theirportrayal.

4. Round the figure up to the next higherhundred foot level.

Example: Elevation of obstacle top (MSL) = 3450Possible vertical error + 100Obstacle Allowance 200

equals 3750Raise to the following 100 foot level 3800

Maximum Elevation Figure

Pilots should be aware that while the MEF isbased on the best information available to the cartogra-

pher, the figures are not verified by field surveys. Also,users should consult the Aeronautical Chart Bulletin inthe A/FD or NACO website to ensure that your chart hasthe latest MEF data available.

RADIO AIDS TO NAVIGATION

On visual charts, information about radio aids tonavigation is boxed, as illustrated. Duplication of data isavoided. When two or more radio aids in a general areahave the same name with different frequencies, TACANchannel numbers, or identification letters, and no misin-terpretation can result, the name of the radio aid may beindicated only once within the identification box. VHF/UHF radio aids to navigation names and identificationboxes (shown in blue) take precedence. Only those itemsthat are different (e.g., frequency, Morse Code) arerepeated in the box in the appropriate color. The choiceof separate or combined boxes is made in each case onthe basis of economy of space and clear identification ofthe radio aids.

Radio aids to navigation located on an airportdepicted by the pattern symbol may not always beshown by the appropriate symbol. A small open circleindicates the NAVAID location when co-located with anairport symbol. The type of radio aid to navigation maybe indicated by letter identification; e.g., VOR, VORTAC,etc., positioned on and breaking the top line of the iden-tification box.

AIRPORTS

Airports in the following categories are charted asindicated (additional symbols are shown later in this Sec-tion).

Public use airports:

Hard-surfaced runways greater than 8069' or

some multiple runways less than 8069'

Hard-surfaced runways 1500' to 8069'

Other than hard-surfaced runways

Seaplane bases

Military airports:

Other than hard-surfaced runways

Hard-surfaced runways are depicted the sameas public-use airports.

U.S. military airports are identified by abbrevia-tions such as AAF (Army Air Field), AFB (Air ForceBase), MCAS (Marine Corps Air Station), NAS(Naval Air Station), NAF (Naval Air Facility), NAASNaval Auxiliary Air Station), etc. Canadian militaryairports are identified by the abbreviation DND(Department of National Defense).

Services available:

Tick marks around the basic airport symbol indi-

cate that fuel is available and the airport is tendedduring normal working hours. (Normal workinghours are Monday through Friday 10:00 A.M. to4:00 P.M. local time.)

Other airports with or without services:

Airports are plotted in their true geographic posi-tion unless the symbol conflicts with a radio aid to navi-

gation (navaid) at the same location. In such cases, theairport symbol will be displaced, but the relationshipbetween the airport and the navaid will be retained.

Airports are identified by their designated nameGeneric parts of long airport names (such as "airport,"field or "municipal") and the first names of persons arecommonly omitted unless they are needed to distinguishone airport from another with a similar name.

The following figure illustrates the coded datathat is provided along with the airport name. The eleva-tion of an airport is the highest point on the usable por-tion of the landing areas. Runway length is the length ofthe longest active runway including displaced thresholds

{

and excluding overruns. Runway length is shown to thenearest 100', using 70 as the division point; a runway8070' in length is charted as 81, while a runway 8069' inlength is charted as 80.

Airports with Control Towers (CT), and theirrelated information, are shown in blue. All other airports,and their related information, are shown in magenta (red-dish purple).

The symbol indicates the existence of a rotat-ing or flashing airport beacon operating continuouslysunset to sunrise.

The symbol indicates that runway lights are on

during hours of darkness. A indicates that the pilotmust consult the Airport/Facility Directory (A/FD) todetermine runway lighting limitations, such as: availableon request (by radio call, letter, phone, etc), part-timelighting or pilot/airport controlled lighting. The lighted run-way may not be the longest runway available, and maynot be lighted full length. A detailed description of airportand air navigation lighting aids available at each airportcan be found in the A/FD. The Aeronautical InformationManual (AIM) thoroughly explains the types and uses ofairport lighting aids.

CONTROLLED AIRSPACE

Controlled airspace consists of those areaswhere some or all aircraft may be subject to air trafficcontrol, such as Class A, Class B, Class C, Class DClass E Surface (SFC) and Class E Airspace.

Class A Airspace

within the United Statesextends from 18,000' up to 60,000' MSL. While visuacharts do not depict Class A, it is important to note its

existance.

Class B Airspace

is shown in abbreviated formon the World Aeronautical Chart (WAC). The Sectiona

Aeronautical Chart (Sectional) and Terminal Area Chart(TAC) show Class B in greater detail. The MSL ceiling andfloor altitudes of each sector are shown in solid blue fig-

ures with the last two digits omitted: Radials and

arcs used to define Class B are prominently shown onTACs. Detailed rules and requirements associated withthe particular Class B are shown. The name by which

the Class B is identified is shown as:

Class C Airspace

is shown in abbreviated formon WACs. Sectionals and TACs show Class C in greatedetail.

The MSL ceiling and floor altitudes of each sectorare shown in solid magenta figures with the last two dig-

its eliminated: . The following figures identify a sec-

tor that extends from the surface to the base of the Class

B: . The name by which the Class C is identified is

shown as: . Separate notes, enclosedin magenta boxes, give the approach control frequencies

to be used by arriving VFR aircraft to establish two-wayradio communication before entering the Class C (gener-

ally within 20 NM):

Class D Airspace

is symbolized by a bluedashed line. Class D operating less than continuous is

indicated by the following note: . Ceilings

of Class D are shown as follows: . A minus in fron

of the figure is used to indicate "from surface to but notincluding .... .

Class E Surface (SFC) Airspace

is symbolized

by a magenta dashed line. Class E SFC operating lessthan continuous is indicated by the following note

Class E Airspace

ex ists at 1200' aboveground level unless desig-nated otherwise. The lat-eral and vertical limits of allClass E up to but not including 18,000' are shown bynarrow bands of vignette on Sectionals and TACs. Con-trolled airspace floors of 700' above the ground aredefined by a magenta vignette; floors other than 700


6/67


that abut uncontrolled airspace (Class G) are defined bya blue vignette; differing floors greater than 700' above

the ground are annotated by a symbol and a

number indicating the floor. If the ceiling is less than18,000' MSL, the value (prefixed by the word "ceiling") isshown along the limits of the controlled airspace. Theselimits are shown with the same symbol indicated above.

UNCONTROLLED AIRSPACE

Class G Airspace

within the United Statesextends up to 14,500' MSL. At and above this altitude isClass E, excluding the airspace less than 1500' abovethe terrain and certain special use airspace areas.

SPECIAL USE AIRSPACE

Special use airspace confines certain flight activ-ities and restricts entry, or cautions other aircraft operat-ing within specific boundaries. Except for ControlledFiring Areas, special use airspace areas are depicted onvisual aeronautical charts. Controlled Firing Areas are not

charted because their activities are suspended immedi-ately when spotter aircraft, radar, or ground lookout posi-tions indicate an aircraft might be approaching the area.Nonparticipating aircraft are not required to change theirflight paths. Special use airspace areas are shown in theirentirety (within the limits of the chart), even when theyoverlap, adjoin, or when an area is designated withinanother area. The areas are identified by type and identi-fying name or number, positioned either within or imme-diately adjacent to the area.

OTHER AIRSPACE AREAS

Mode C Required Airspace

(from the surface to10,000' MSL) within 30 NM radius of the primary air-port(s) for which a Class B is designated, is depicted by

a solid magenta line. Mode C is

required but not depicted for operations within andabove all Class C up to 10,000' MSL. Enroute Mode Crequirements (at and above 10,000' MSL except in air-

space at and below 2500' AGL) are not depicted. SeeFAR 91.215 and the AIM.

FAR 93

Airports and heliportswhere Federal Aviation Regulation (FAR93) special air traffic rules and airporttraffic patterns apply are shown by"boxing" the airport name.

FAR 91

Airports where fixed wing special visua

flight rules operations are prohibited (FAR 91) are shownwith the type "NO SVFR" above the airport name.

National Security Areas

are indicated on VFRcharts with a broken magenta line.Unauthorized aircraft are requested to remain clear ofthese areas.

Terminal Radar Service Areas (TRSAs)

areshown in their entirety, symbolized by a screened blackoutline of the entire area including the various sectors

within the area.

The outer limit of the entire TRSA is a continuousscreened black line. The various sectors within the TRSA

are symbolized by slightly narrower screened black linesEach sector altitude is identified in solid black

color by the MSL ceiling and floor values of the respec-tive sector, eliminating the last two digits. A leader line isused when the altitude values must be positioned out-side the respective sectors because of space limitations

The TRSA name is shown near the north position of the

TRSA as follows: . Associated frequcies are listed in a table on the chart border.

Military Training Routes (MTRs)

are shown onSectionals and TACs. They are identified by the routedesignator: . Route designators

are shown in solid black on the route centerline, posi-tioned along the route for continuity. The designator IR or

VR is not repeated when two or more routes are estab-lished over the same airspace, e.g., IR201-205-227Routes numbered 001 to 099 are shown as IR1 or VR99eliminating the initial zeros. Direction of flight along theroute is indicated by small arrowheads adjacent to and inconjunction with each route designator.

The following note appears on Sectionals andTACs covering the conterminous United States.

There are IFR (IR) and VFR (VR) routes as follows

Route identification:

a. Routes at or below 1500' AGL (with no seg-ment above 1500') are identified by four-digitnumbers; e.g., VR1007, etc. These routes are


7/67


generally developed for flight under VisualFlight Rules.

b. Routes above 1500' AGL (some segments ofthese routes may be below 1500') are identi-fied by three-digit or less numbers; e.g., IR21,

VR302, etc. These routes are developed forflight under Instrument Flight Rules.

MTRs can vary in width from four to 16 miles.

Detailed route width information is available in the FlightInformation Publication (FLIP) AP/1B (a DoD publication),or in the Digital Aeronautical Chart Supplement (DACS)produced by NACO.

Special Military Activity

areas are indicated onthe Sectionals by a boxed note in black type. The notecontains radio frequency information for obtaining areaactivity status.

TERMINAL AREA CHART (TAC) COVERAGE

TAC coverage is shown on appropriate Section-als by a 1/4" masked line as indicated below. Within thisarea, pilots should use TACs which provide greater detailand clarity of information. A note to this effect appearsnear the masked boundary line.

INSET COVERAGE

Inset coverage is shown on appropriate Section-als by a 1/8" masked line as indicated below. A note to

this effect appears near the masked boundary line.

37 IFR AERONAUTICAL CHARTS

EXPLANATION OF IFR ENROUTE TERMS AND SYMBOLS

The discussions and examples in this section will be based primarily on the IFR (Instrument Flight Rule)Enroute Low Altitude Charts. Other IFR products use similar symbols in various colors (see Section 3 of this guide)

The chart legends list aeronautical symbols with a brief description of what each symbol depicts. This section wilprovide a more detailed discussion of some of the symbols and how they are used on IFR charts.

NACO charts are prepared in accordance with specifications of the Interagency Air Cartographic Committee(IACC), and are approved by representatives of the Federal Aviation Administration and the Department of DefenseSome information on these charts may only apply to military pilots.

AIRPORTS

All active airports with hard-surfaced runways of

3000' or longer are shown on FAA IFR Enroute Charts.

All active airports with approved instrument approach

procedures are also shown regardless of runway length

or composition. Charted airports are classified according

to the following criteria:

Blue Airports with an approved Department of

Defense (DoD) Low Altitude Instrument Approach Pro-

cedure and/or DoD RADAR MINIMA published in

DOD FLIP (Flight Information Publication or the FAA

U.S. Terminal Procedures Publication (TPP).

Green

Airports and seaplane bases with an

approved Low Altitude Instrument Approach Proce-

dure published in the FAA TPP volumes.

Brown

Airports and seaplane bases that do not

have a published Instrument Approach Procedure.

Airports are plotted in their true geographic posi-

tion unless the symbol conflicts with a radio aid to navi-

gation (NAVAID) at the same location. In such cases, the

airport symbol will be displaced, but the relationship

between the airport and the NAVAID is retained.

Airports are identified by the airport name. In the

case of military airports, the abbreviated letters AFB (Air

Force Base), NAS (Naval Air Station), NAF (Naval Air

Facility), MCAS (Marine Corps Air Station), AAF (Army Air

Field), etc., appear as part of the airport name.

Airports marked "Pvt" immediately following the

airport name are not for public use, but otherwise meet

the criteria for charting as specified above.

Runway length is the length of the longest active

runway (including displaced thresholds but excluding

overruns) and is shown to the nearest 100 feet using 70

feet as the division point; e.g., a runway of 8,070' is

labeled 81.

The following runway compositions (materials)

constitute a hard-surfaced runway: asphalt, bitumen

concrete, and tar macadam. Runways that are not

hard-surfaced have a small letter "s" following the run-

way length, indicating a soft surface.

A symbol following the elevation under the air

port name means that runway lights are in operation

sunset to sunrise. A symbol indicates there is Pilot

Controlled Lighting. A symbol means the lighting is

part-time or on request. The pilot should consult the Air-

port/Facility Directory for light operating procedures. TheAeronautical Information Manual thoroughly explains the

types and uses of airport lighting aids.

RADIO AIDS TO NAVIGATION (NAVAIDs)

All IFR radio NAVAIDs that have been flight-

checked and are operational are shown on IFR enroute

charts. VHF/UHF NAVAIDs (VORs, TACANs, and UHF

NDBs) are shown in black, and LF/MF NAVAIDs (Com-

pass Locators and Aeronautical or Marine NDBs) are

shown in brown.

SPECIAL USE AIRSPACE

Special use airspace confines certain flight activ-

ities or restricts entry, or cautions other aircraft operating

within specific boundaries. Special use airspace areas

are depicted on aeronautical charts. Special use air-

space areas are shown in their entirety, even when they

overlap, adjoin, or when an area is designated within

another area. The areas are identified by type and identi-

fying number or name (R4001), effective altitudes, oper-ating time, weather conditions (VFR/IFR) during which

the area is in operation, and voice call of the controlling

agency, on the back or front panels of the chart. Special

Use Airspace with a floor of 18,000' MSL or above is not

shown on the Enroute Low Altitude Charts. Similarly,

Special Use Airspace with a ceiling below 18,000' MSL

is not shown on Enroute High Altitude Charts.

OTHER AIRSPACE

Mode C Required Airspace

(from the surface to

10,000' MSL) within 30 NM radius of the primary air-

port(s) for which a Class B airspace is designated, is

depicted on Enroute Low Altitude Charts. Mode C is also

depicted within 10 NM of all airports listed in Appendix D

of FAR 91.215 and the Aeronautical Information Manual

(AIM).

Mode C is required within the limits of a Class C airspace

up to 10,000' MSL.

INSTRUMENT AIRWAYS

The FAA has established two fixed route systems

for air navigation. The VOR and LF/MF (low or medium

frequency) systemdesignated from 1,200' AGL to but

not including 18,000' MSLis shown on Low Altitude

Enroute Charts, and the Jet Route systemdesignated

from 18,000' MSL to FL 450 inclusiveis shown on

High Altitude Enroute Charts.

VOR LF/MF AIRWAY SYSTEM(LOW ALTITUDE ENROUTE CHARTS)

In this system VOR airwaysairways based on

VOR or VORTAC NAVAIDsare depicted in black and

identified by a "V" (Victor) followed by the route number

(e.g., "V12"). In Alaska, some segments of low-altitude

airways are based on LF/MF navaids and are charted in

brown instead of black.

LF/MF airwaysairways based on LF/MF

NAVAIDsare sometimes called "colored airways"

because they are identified by color name and number

(e.g., "Amber One", charted as "A1"). Green and Red air-

ways are plotted east and west, and Amber and Blue air-

ways are plotted north and south. Regardless of their

color identifier, LF/MF airways are shown in brown. U.S

colored airways exist only in Alaska, those within the

conterminous U.S. have been rescinded. (Note: In Mexi-

can airspace on FAA charts, LF/MF airways are charted

in black).

AIRWAY/ROUTE DATA

On both series of Enroute Charts, airway/route

data such as the airway identifications, bearings or radi-

als, mileages, and altitude (e.g., MEA, MOCA, MAA) are

shown aligned with the airway and in the same color as

the airway.

Airways/Routes predicated on VOR or VORTAC

NAVAIDs are defined by the outbound radial from the

NAVAID. Airways/Routes predicated on LF/MF NAVAIDs

are defined by the inbound bearing.

AREA NAVIGATION (RNAV) T ROUTE SYSTEM(LOW ALTITUDE ENROUTE CHARTS)

The FAA has created new low altitude area navi-

gation (RNAV) routes for the en route and terminal envi-

ronments. The RNAV routes will provide more direc

routing for IFR aircraft and enhance the safety and effi-ciency of the National Airspace System. To utilize these

routes aircraft will need to be equipped with IFR

approved Global Navigation Satellite System (GNSS). In

Alaska, TSO-145a and 146a equipment is required.

Low altitude RNAV only routes are identified by

the letter T prefix, followed by a three digit number (T-

200 to T-500). Routes are depicted in aeronautical blue

on the IFR Enroute Low Altitude charts. RNAV route

data (route line, identification boxes, mileages, way-

points, waypoint names, magnetic reference bearings

and MEAs) will also be printed in aeronautical blue.

Magnetic reference bearings will be shown originating

from a waypoint, fix/reporting point or NAVAID. A GNSS

minimum IFR en route altitude (MEA) for each segment

will be established to ensure obstacle clearance and

communications reception. MEAs will be identified with

a G suffix..

Joint Victor/RNAV routes will be charted as out-

lined above except as noted. The joint Victor route and

the RNAV route identification box shall be shown adja-

cent to each other. Magnetic reference bearings will not

be shown. MEAs will be stacked in pairs or in two sepa-

rate columns, GNSS and Victor. On joint routes, RNAV

specific information will be printed in blue.

OFF ROUTE OBSTRUCTION CLEARANCE ALTI-TUDE (OROCA)

The Off Route Obstruction Clearance Altitude

(OROCA) is represented in thousands and hundreds of

feet above mean sea level. The OROCA represents the

highest possible elevation including both terrain and

other vertical obstructions (towers, trees., etc.) bounded

by the ticked lines of latitude and longitude. In this exam-

ple the OROCA represents 12,500 feet.

OROCA is computed just as the Maximum Ele-

vation Figure (MEF) found on Visual charts except that itprovides an additional vertical buffer of 1,000 feet in des-

ignated non-mountainous areas and a 2,000 foot vertical

buffer in designated mountainous areas within the United

States. Unlike a MEF, when determining an OROCA the

area 4 NM around each quadrant is analyzed for

obstructions. Evaluating the area around the quadrant

provides the chart user the same lateral clearance an air-

way provides should the line of intended flight follow a

ticked line of latitude or longitude. OROCA does not pro-

vide for NAVAID signal coverage, communication cover-

age and would not be consistent with altitudes assigned

by Air Traffic Control. OROCAs can be found over all land

masses and open water areas containing man-made

obstructions (such as oil rigs). OROCAs are shown in

every 30 x 30 minute quadrant on Area Charts, every

one degree by one degree quadrant for U.S. Low Alti-

tude Enroute Charts and every two degree by two

degree quadrant on Alaska Low Enroute Charts.

MILITARY TRAINING ROUTES (MTRs)

Military Training Routes (MTRs) are routes estab-

lished for the conduct of low-altitude, highspeed military

flight training (generally below 10,000 feet MSL at air-

speeds in excess of 250 knots IAS). These routes are

depicted in brown on Enroute Low Altitude Charts, and

are not shown on inset charts or on IFR Enroute High

Altitude Charts. Enroute Low Altitude Charts depict all IR

(IFR Military Training Route) and VR (VFR Military Training

Route) routes, except those VRs that are entirely at or

below 1500 feet AGL.

Military Training Routes are identified by designa-

tors (IR-107, VR-134) which are shown in brown on the

route centerline. Arrows indicate the direction of flight

along the route. The width of the route determines the

width of the line that is plotted on the chart:

Route segments with a width of 5 NM or less

both sides of the centerline, are shown by a .02"

line.

Route segments with a width greater than 5 NM

either or both sides of the centerline, are shown by a

.035" line.

JET ROUTE SYSTEM (HIGH ALTITUDE EN-ROUTE CHARTS)

Jet routes are based on VOR or VORTAC

navaids, and are depicted in black with a "J" identifier fol-

lowed by the route number (e.g., "J12"). In Alaska, some

segments of jet routes are based on LF/MF navaids and

are shown in brown instead of black.

AREA NAVIGATION (RNAV) Q ROUTE SYSTEM (HIGH ALTITUDE ENROUTE CHARTS)

The FAA has adopted certain amendments to

Title 14, Code of Federal Regulations which paved the

way for the development of new area navigation (RNAV)

routes in the U.S. National Airspace System (NAS)

These amendments enable the FAA to take advantage of

technological advancements in navigation systems such

as the Global Positioning System (GPS). RNAV Q

Route MEAs are shown when other than 18,000. MEAs

for GNSS RNAV aircraft are identified with a G suffix

MEAs for DME/DME/IRU RNAV aircraft do not have a

G suffix.. RNAV routes and associated data are charted

in aeronautical blue. Magnetic reference bearings are

shown originating from a waypoint, fix/reporting point, or

NAVAID. Joint Jet/RNAV route identification boxes will be

located adjacent to each other with the route charted in

black. With the exception of Q-Routes in the Gulf of

Mexico, GNSS or DME/DME/IRU RNAV are required,

unless otherwise indicated. Radar monitoring is required.

DME/DME/IRU RNAV aircraft should refer to the A/FD for

DME information. Altitude values are stacked highest to

lowest.

TERRAIN CONTOURS ON AREA CHARTS

The National Transportation Safety Board (NTSB)

recently recommended that terrain be added to Area

Charts to increase pilots situational awareness of terrain

in the terminal area and to increase the safety of flight.

When the terrain on an Area Chart rises at least 1000

above the airport elevation, terrain will be depicted in

shades of brown. The initial contour value (lowest eleva-

tion) depicted will be at least 1000, but no more than

2000 above the airport elevation. The initial contour

value may be less than 1000 only if needed to depict a

rise in terrain close to the airport. Subsequent contour

values will be depicted at a whole 1000 increment

(2000/4000, etc., NOT 2500/4500, etc.). The follow-

ing Area Charts are affected: Anchorage, Denver, Fair-

banks, Juneau, Los Angeles, Phoenix, Prudhoe Bay, San

Francisco and Vancouver.

U.S. TERMINAL PROCEDURES PUBLICATION 52

EXPLANATION OF TPP TERMS AND SYMBOLS

The discussions and examples in this section will be based primarily on the IFR (Instrument Flight Rule) Ter-minal Procedures Publication (TPP). Other IFR products use similar symbols in various colors (see Section 2 of thisguide). The publication legends list aeronautical symbols with a brief description of what each symbol depicts. Thissection will provide a more detailed discussion of some of the symbols and how they are used on TPP charts.

NACO charts are prepared in accordance with specifications of the Interagency Air Cartographic Committee(IACC), which are approved by representatives of the Federal Aviation Administration, and the Department ofDefense. Some information on these charts may only apply to military pilots.

PILOT BRIEFING INFORMATION

The pilot briefing information format consists ofthree horizontal rows of boxed procedure-specific infor-mation along the top edge of the chart. Altitudes, fre-

quencies and channel, course and elevation values

(except HATs and HAAs) are charted in bold type. Thetop row contains the primary procedure navigation infor-mation, final approach course, landing distance avail-able, touchdown zone and airport elevations. Themiddle row contains procedure notes and limitations,icons indicating if nonstandard alternate and/or take-offminimums apply, approach lighting symbology, and thefull text description of the missed approach procedure.

The bottom row contains air to ground communicationfacilities and frequencies in the order in which they areused during an approach with the tower frequency boxbolded.

NOTE: The symbol indicates that outages of theWAAS vertical guidance may occur daily at this loca-tion due to initial system limitations. WAAS NOTAMsfor vertical outages are not provided for this approach.Use LNAV minima for flight planning at these locations,whether as a destination or alternate. For flight opera-tions at these locations, when the WAAS avionics indi-cate that LNAV/VNAV or LPV service is available, thenvertical guidance may be used to complete theapproach using the displayed level of service. Shouldan outage occur during the procedure, reversion toLNAV minima may be required. As the WAAS cover-

age is expanded, the will be removed.

MISSED APPROACH ICONS

In addition to the full text description of themissed approach procedure contained in the notes sec-tion of the middle-briefing strip, the steps are alsocharted as boxed icons in the chart profile view. These

icons provide simple-to-interpret instructions, such as

direction of initial turn, next heading and/or course, nextaltitude, etc.

RNAV CHART MINIMA

RNAV instrument approach procedure charts wilnow incorporate all types of approaches using Area Nav-igation systems, both ground based and satellite basedBelow is an explanation of the RNAV minima.

The standard format for RNAV minima (and land-ing minima) is as shown below. RNAV minima are

dependent on navigational equipment capability, asstated in the applicable AFM or AFMS, or other FAAapproved document, and as outlined below.

GLS (Global Navigation Satellite System (GNSS)

Landing System)

The GLS (NA) Minima line will be removed fromthe existing RNAV (GPS) approach charts when LPVminima is published.

LPV (An Approach Procedure with Vertical Guid-ance (APV) and precise lateral based on WAAS

Must have WAAS (Wide Area Augmentation Sys-tem) avionics approved for LPV approach.

LNAV/VNAV (Lateral Navigation/Vertical Naviga-tion)

Must have either:a.) WAAS avionics approved for LNAV/VNAV

approach, or

b.) A certified Baro-VNAV system with an IFRapproach approved GPS, or

c.) A certified Baro-VNAV system with an IFRapproach approved WAAS, or

d.) An approach certified RNP-0.3 system..

Other RNAV approach systems require speciaapproval.

1. LNAV/VNAV minima not applicable for Baro-VNAV equipment if chart is annotated Baro-VNAV NAor when below the minimum published temperature,e.g., Baro-VNAV NA below -17 C (2 F).

2. DME/DME based RNP-0.3 systems may beused only when a chart note indicates DME/DME avail-ability; e.g., DME/DME RNP-0.3 Authorized. SpecificDME facilities may be required; e.g., DME/DME RNP-0.3 Authorized, ABC, XYZ required.

LNAV (Lateral Navigation)

Must have IFR approach approved GPS, WAAS,or RNP-0.3 system. Other RNAV systems require specialapproval.

NOTE:

DME/DME RNP-0.3 systems may be usedonly when a chart note indicates DME/DME availabil-ity; e.g., "DME/DME RNP-0.3 Authorized." SpecificDME facilities may be required; e.g., "DME/DME RNP-0.3 Authorized. ABC, XYZ required."

TERMINAL ARRIVAL AREAS (TAAs)

The objective of the Terminal Arrival Area (TAA) isto provide a seamless transition from the enroute struc-ture to the terminal environment for arriving aircraftequipped with Flight Management System (FMS) and/orGlobal Positioning System (GPS) navigational equip-ment. The underlying instrument approach procedure isan area navigation (RNAV) procedure. The TAA containswithin it a T structure that normally provides for a NoProcedure Turn (NoPT) for aircraft using the approach.

The TAA provides the pilot and air traffic controller with avery efficient method for routing traffic into the terminalenvironment with little required air traffic control interface,

and with minimum altitudes depicted that provide stan-dard obstacle clearance compatible with the instrumentprocedure associated with it. The TAA will not be foundon all RNAV procedures, particularly in areas of heavyconcentration of air traffic. When the TAA is published, itreplaces the MSA for that approach procedure. TAAsmay appear on current and new format GPS and RNAVIAP charts.

The standard TAA consists of three areas definedby the extension of the Initial Approach Fix (IAF) legs andthe intermediate segment course. These areas are calledthe straight-in, left-base, and the right-base areas. TAA

area lateral boundaries are identified by magneticcourses TO the IAF. The straight-in area can further bedivided into pie-shaped sectors with the boundariesidentified by magnetic courses TO the IF/IAF, and manycontain stepdown sections defined by arcs based onRNAV distances (DME or ATD) from the IF/IAF. The right/left-base areas can only be subdivided using arcs basedon RNAV distances from the IAFs for those areas.

Straight-In Area: The straight-in area is defined by asemi-circle with a 30 NM radius centered on andextending outward from the IF/IAF. The altitude shownwithin the straight-in area icon provides minimum IFR

obstacle clearance

Base Areas: the left and right base areas are boundedby the straight-in TAA and the extension of the inter-mediate segment course. The base areas are definedby a 30 NM radius centered on the IAF on either sideof the IF/IAF. The IF/IAF is shown in the base areaicons without its name. The altitude shown within thebase area icons provides minimum IFR obstacle clear

ance.

Minimum MSL altitudes are charted within eachof these defined/subdivisions that provide at least 1,000feet of obstacle clearance, or more as necessary inmountainous ares

NOTE: Additional information for the TAAs can befound in the Aeronautical Information Manual (AIMPara 5-4-5-d.

ALTERNATE MINIMUMS

When an alternate airport is required, standardIFR alternate minimums apply. Precision approach pro-cedures require a 600 ceiling and 2 statute miles visibil-ity; nonprecision approaches require an 800 ceiling and2 statute miles visibility. When a appears in the Notessection of the approach chart, it indicates non-standardIFR alternate minimums exist for the airport. This infor-

mation is found in Section E of the TPP. If appearsalternate minimums are not authorized due to unmoni-tored facility or absence of weather reporting serviceCivil
