Overlying High Altitude Airway/Route

Oceanic Transition Route

RNAV Airway/Route

Compulsory Reporting Point

Non-Compulsory Reporting Point

Low Altitude Compulsory Reporting Point

Low Altitude Non-Compulsory Reporting Point.

Mileage Break/Turning Point

RNAV Waypoint

Meteorological report required (unless instructed otherwise), giving air temperature, wind, icing, turbulence, clouds and other significant weather. Report to controlling ground station, or station indicated.

Holding Pattern. DME figures, when provided, give the DME distance of the fix as the first figure followed by the outbound limit as the second figure.

Length of holding pattern in minutes when other than standard.

Database identifiers are enclosed in brackets [ ABROC]. Database identifiers are officially designated by the controlling authority or they may be derived by Jeppesen. In either case, these identifiers have no ATC function and should not be used in filing flight plans nor should they be used when communicating with ATC. They are shown only to enable the pilot to maintain orientation when using charts in concert with database navigation systems.

Fix name with Minimum Crossing Altitude ( MCA) showing airway, altitude, and direction, and Minimum Reception Altitude ( MRA).

Official fix name (with country assigned identifier in parentheses. Several countries throughout the world assign identifiers for use in flight plans.

LF bearings forming a fix are to the navaid.

VHF radials forming a fix are from the navaid.

VHF frequency and identifier included when off chart or remoted.

LF frequency, identifier and Morse Code included when off chart or remoted.

Arrow along airway points from the navaid designating the reporting point. Other published radials may be used if they are greater than 30 degrees from the airway being used and are not beyond the COP.

Fix formed by 55 DME from MAZ navaid.

“D” indicates DME fix and distance from the station that provides the DME mileage.

Airway and route designators. Negative (white letters in black) designators are used for distinction.

One Way Airway

Suffix 1 or 1, 2 or 1, 2, 3 gives the Conditional Route Category (Europe).

MEA (Minimum Enroute Altitude),shown as altitude or flight level.

MEA is established with a gap in nav-signal coverage.

Directional MEAs as indicated.

GPS MEA

MOCA (Minimum Obstruction Clearance Altitude).

Route MORA (Route Minimum Off-Route Altitude). See glossary.

MAA (Maximum Authorized Altitude), shown as altitude or flight level.

MEA change, limit of MAA applicability or MAA change. Also MOCA or MORA change when MOCA or MORA is charted with no MEA. Symbol is omitted at navaid.

Mileages. Total mileage between navaids is positioned along respective airway centerline. Total mileage may have directional pointers when there are multiple airway designators. The pointers parallel the airway centerlines along which the mileage applies.

VOR radial & route bearings (magnetic)

VOR Radial and route bearings (true)

ADF Bearings (inbound or outbound). Bearings are magnetic unless followed by a “T” indicating True.

ADF Bearings include an arrow to indicate the direction of flight or, when used to designate Fixes, direction to the station. In remote or oceanic areas where ground based navigation aids are not available, the arrow indicates the direction of flight.

ADF bearings (True at track midpoint).

The navigation frequency COP (changeover point) between two stations is indicated by mileages from the station to the point of change. Omitted when at midpoint or turning point.

Means even thousands altitudes/flight levels are used in the direction of the arrow and odd thousands in the opposite direction. For application of this symbol above FL 290, the left half of the cruising level rose is considered even. The symbol is shown where altitude/flight level assignment is opposite that shown in the standard cruising altitude/flight level rose.

Means all altitudes, even and odd, are available in the direction indicated.

Means odd thousands altitude/flight level per the above definition. “O” is used only on one way airways to show that odd altitude/flight level assignments apply.

Prior Permission Required from ATC for flight in the direction of the arrow.

Flight Planned Route describes any route or portion thereof that is identical to that filed in the flight notification and sufficient routing details are given to definitely establish the aircraft on its route.

Airway J26 does not utilize the navaid or reporting point.

Airway J14 turns at the navaid or reporting point but does not utilize them. A mileage break “X” is included to further indicate a turn point.

Airway V76 does not utilize the navaid. A note indicating the proper use of the navaid is included.

Airway V76 does not utilize the Int. A note indicating the proper use of the Int is included.
