  1. Chapter 2 Enroute/Aera Charts §2.1 Introduction §2.2 Layout of Enroute Charts §2.3 Navaids §2.4 Airway/Route components §2.5 Airports §2.7 Boundaries §2.8 Holding Pattern §2.9 Communication Procedures §2.10 Area Charts §2.11 RNAV Enroute Charts §2.12 Legends of Enroute Charts

  2. The information in enroute charts includes: • Airway sturcture • Controlled airspace limitation • Navaids • Airports • Communication frequencies • Minimum enroute altitude (MEA)/Minimum obstacle clearance altitude (MOCA)

  3. Mileage • Reporting points • Special used airspace (SUA) • Other required information

  4. § 2.1.1 Type of Enroute Charts 1.Low altitude enroute charts 2.High altitude enroute charts 3. High/low altitude enroute charts 4. Area charts

  5. §2.1.2 New Format Charts

  6. §2.1.3 Selecting an Enroute Chart The first step, however, is to turn to the Enroute Tab in your Airway Manual. The Enroute Table of Contents page found behind this tab lists the various pages relating to enroute operations filed in your manual.

  7. U.S. low altitude Enroute chart index

  8. U.S. High altitude Enroute chart index

  9. §2.2 Layout of Enroute Charts§2.2.1 Front and Back Panel Front Panel

  10. Back Panel

  11. Information typically found on the front and back panel includes the: • Heading Information • Coverage Index Diagram • Changes Note • Communications Tabulations • SUA Tabulations • Cruising Altitudes/Levels • Cross-Reference Notes

  12. §2.2.1.1 Heading Information In addition to the region of coverage and chart type, the enroute chart heading information includes three important chart components: • Number • Scale • Dates

  13. §2.2.1.2 Coverage Index Diagram 1.Chart boundaries 2.Major cities 3.Political/state boundaries 4.Time zones 5.Area chart 6.Chart usage statement

  14. §2.2.1.3 Change note A changes note highlights significant items that have been modified on the chart since the last revision for each chart.

  15. §2.2.1.4 Communications Tabulations Each enroute chart contains a tabulation of air traffic control (ATC) communicationservices and frequencies within its coverage. The information includes frequencies and voice/radio call names for approach, departure, tower, and ground control, as well as services availability.

  16. √ √ √ √

  17. Communication information of any given geographic region is described in the Comm Tabs. In general, this information includes: • City name • Area chart code • Code of the section of the panel • Call name • Communication services

  18. P=Panel • 4=The panel number • B=The section of the panel

  19. §2.2.3 Border Information

  20. §2.2.4 Panel Navigation There is some panel navigation information in the enroute chart border. Once you have needed chart in hand, there are several ways to quickly find the information that you may need, including: • ZIGDEX and Panel Numbers • Enroute chart overlap indicators • Area chart overlap indicators • “To Notes”

  21. §2.3 Navaids The Navaid components covered in this lesson include: • Symbology • Facility Information Boxes • Communications

  22. §2.3.1 Symbology • VOR on Low and High/Low Charts • VOR on High Charts • VORTAC or VORDME • TACAN or DME • NDB on Low and High/Low Charts • NDB on High Charts • Compass Locator • Localizer • Marker beacons • GPS as a substitute

  23. §2.3.1.1VOR on Low and High/Low Charts Every VOR symbol on low and high/low enroute charts has a compass rose surrounding the location of the VOR and the 360° radial to indicate magnetic north.

  24. §2.3.1.2 VOR on High Charts

  25. §2.3.1.3 VORTAC or VORDME The single line extending from the symbol corresponds to a 360°radial to indicate magnetic north. The small tick at the end of the line is used to measure magnetic courses with the PV-5 plotter.

  26. §2.3.1.4 TACAN or DME Most TACAN stations without a co-located VOR can be used by civilian DME units. Pure TACANs do not have compass roses since the azimuth cannot be used by most civilian pilots. Jeppesen’s symbol, a serrated circle, represents both TACAN and DME facilities.

  27. §2.3.1.5 NDB on Low and High/Low Charts NDBs are shown on Jeppesen Low and High/Low altitude enroute charts as a series of dots forming three concentric circles. The single line extending from the symbol corresponds to magnetic north. The small tick at the end of the line is used to measure magnetic bearings with the PV-5 plotter.

  28. §2.3.1.6 NDB on High Charts For legibility purposes, on High and High/Low altitude enroute charts, Nondirectional Beacins(NDBs) symbols are reduced in size since the charts cover more area; that is, the scales are smaller than on Low charts. The magnetic north pointer on NDB symbol is included to make it easier to measure magnetic bearings with a plotter.

  29. §2.3.1.7 Compass Locator Compass Locator symbols look similar to an NDB symbol. They are only shown on enroute charts when providing an enroute function or Transcribed Weather Broadcast (TWEB).

  30. §2.3.1.8 Localizer Localizers are usually employed to provide course and distance information with respect to a runway during an approach, but in some instances localizers may also be combined with other facilities, fixes, or reporting points to form an enroute intersection.

  31. §2.3.1.9 Marker beacons • Markers with collocated Locator or NDB • Markers with collocated airspace fix or intersection

  32. §2.3.2 Facility Information Boxes The facility box gives the name, frequency, two- or three-letter identifier, and Morse code identification. Other information may also be displayed, such as coordinates, the class of VOR, and even available communications.

  33. §2.3.2.1 On-Airway On-Airway VOR Navaid information is presented in a shadowed box when the navaid is an airway component. The name of the navaid, its frequency, identifier, and Morse code identification is noted.

  34. Generally, various coverage of VOR are distinguished by letters preceding the Navaid frequencies. Such as: • (T) —Terminal VOR • (L) —Low Altitude VOR • (H) —High Altitude VOR

  35. On-Airway DME

  36. High altitude Navaid On high/low enroute charts, latitude and longitude coordinates are shown at the bottom of the information box for high altitude navaids.

  37. Special L/MF Navaids Some L/MF (low and medium frequency ) navaids are combined in the shadowed box even though they are not the part of the airway structure. They are used for course guidance for over lengthy route segments.

  38. Localizer Navaids Performed an Enroute Function Charts depict localizers to indicate availability at airports.

  39. §2.3.2.2 Off-Airway Navaids On Low and Low/High Enroute Charts Off-airway navaids are unboxed on low and low/high enroute charts.

  40. On high Enroute Charts Off-airway navaids are boxed without a shadow on high altitude enroute charts.

  41. Off-airway TACAN TACAN facilities not associated with a VOR are listed with channel number and a VOR “ghost” frequency. The “ghost” frequency enables civilian users to access the DME signal. Coordinates are only shown on the high altitude charts.

  42. Navaids located at an airport Navaids are used in the airway system but that are located at an airport may have the airport and the navaid information grouped together. The navaid frequency and identifier are located below the location name of airport when the navaid name, location name and airport name are the same.

  43. Marker beacon Marker beacon (or fan beacon) are shown on enroute charts if they identify a particular location along an airway or on the approach to an instrument landing. The marker beacon name and Morse code identification are shown next to the symbol.

  44. §2.3.2.3 Notations • “*”:An asterisk specifies part-time hours of operation. • (DME not Collocated) (TACAN not Collocated): When the TACAN or DME antennae is not collocated with the VOR, this notation is shown below the VOR facility information box.

  45. §2.4 Airway/Route Components The airway information provided on charts, including: • Airway types and designators • Course guidance • Airspace Fixes • Mileage • Altitudes
