Procedure Arc Fix Waypoint Names
Unnamed terminal area fixes along a DME arc procedure are identified with the
first character D. Characters 2 through 4 indicate the radial on which the fix lies.
The last character indicates the arc radius. The radius is expressed by a letter of
the alphabet where A = 1 mile, B = 2 miles, C = 3 miles and so forth. Example:
• EPH252°/24 = D252X
An unnamed waypoint along a DME arc with a radius greater than 26 miles is
identified by the station identifier and the DME radius. Example:
• CPR338°/29 = CPR29
When there are multiple unnamed waypoints along a DME arc with a radius
greater than 26 miles, the station identifier is reduced to two characters, followed
by the radius, and then a sequence character. Examples:
• CPR134°/29 = CP29A
• CPR190° /29 = CP29B
DME step down fixes are identified by the distance and a “D”.
Examples: 138D, 106D, 56D, 3D.
Procedure Fix Waypoints
Marker beacons are identified by the marker type identifier followed by the
runway number. Examples:
• Outer Marker 13R = OM13R
• Middle Marker 21 = MM21
Runway–related fixes – waypoints located at unnamed runway–related fixes are
identified by adding a two–letter prefix to the runway number. The following list
is used to determine the applicable prefix:
Examples: OM25L, MM09, IM23, RW04, RW18L.
For airports with more than one approach to the same runway, the two letter prefix
may change to allow different identifiers for the same waypoint. The first letter
identifies the type of fix and the second letter identifies the type approach as
follows:
• RX – runway extension fix
• FA – VFR final approach fix
• CF – final approach course fix
• FF – final approach fix
• IF – initial approach fix
• OM – outer marker
• MM – middle marker
• IM – inner marker
• BM – back course marker
• MD – minimum descent
altitude
• A – (+ an alpha) step down fix
• RW – runway threshold
• MA – missed approach point
other than RW
• TD – touchdown point inboard

Examples: CI32R, PV15, FN24L.
Unnamed turn points that are part of a procedure are identified as a latitude and
longitude waypoint. These include waypoints (except conditional waypoints)
defined by flying a course or track from a waypoint (except conditional
waypoints) to a radial or DME distance. These waypoints are automatically
entered in a route by selection of a procedure using these waypoints, from the
departures or arrivals page.
Airport reference points are identified by the ICAO identifier.
Duplicate Waypoints
Application of the abbreviation rules may create identical identifiers for different
waypoints. When a duplicate waypoint identifier is entered, the page changes to
the SELECT DESIRED WPT page. The page lists the latitude and longitude of
waypoints with the same identifier and the type of facility or waypoint. Select the
latitude/longitude of the correct waypoint to enter the correct waypoint on the
original page.
Conditional Waypoints
Conditional waypoints may display in the route when selecting a DEPARTURES
or ARRIVALS page procedure. Usually, conditional waypoints cannot be
manually entered on a route or legs page. These waypoints indicate when an event
occurs and are not at a geographically–fixed position. The types of conditions are:
Altitude and course intercept conditional waypoints display on the CDU inside
(parenthesis) marks. The diagram below shows conditional waypoints.
• C( ) – final approach course fix
• F( ) – final approach fix
