Operations
the runway is appended. When the approach is not to a specific
runway, the approach bearing is appended. These codes are:
FF
Final Approach Fix
CF
Final Approach Course Fix (used when necessary to
define a course to the FAF—all VOR DME approaches
require a course fix waypoint).
MA
Missed Approach Point
RW
Runway Fix
Following the characters will either be a runway number, when
associated with a particular runway, or a bearing corresponding to the
course at that waypoint. A missed approach point that corresponds to a
RWY 12 approach, would then be called MA12 if it is not the runway
threshold. If the MAP were the runway threshold, it would be named
RW12. A missed approach point associated with a VOR-A approach,
where there are no published straight-in minimums to any runway, and
where the final approach course is 120 would be named MA120.
Bearing and Distance Waypoints: Distance/bearing waypoints
(sometimes called Rho - Theta waypoints), that are defined as a
bearing and distance from a VHF navaid, are named with the character
"D," followed by the radial on which they are positioned, followed by
a single alpha character from "A" to "Z" that corresponds to a distance
from 1 to 26 nm. Thus a waypoint that is on a 350° radial at 10 nm will
be named D350J and a waypoint that is on the 250 radial at 15 nm
would be named D250O.
Unnamed turn points, intersections, and bearing/distance waypoints:
Idents for unnamed turn points, intersections, or bearing/distance
waypoints (other than VHF navaid distance/bearing), that are not
coincidental with named waypoints, are constructed by using the ident
of the nearest navaid together with the distance (rounded to whole
miles). If the distance is less than 100 nm, the distance follows the
navaid ident. If the distance is 100 nm or more, the last two digits of the
miles are placed in front of the navaid ident. For example:
