WAYPOINT NAMES AND OTHER CONVENTIONS
Terminal Area Waypoints -
where specific identifiers have not been assigned, the following two-character
prefix codes are added to the runway identifier (number) to create terminal area and approach-related waypoints
in the navigation database:
AF
- Initial
Approach
Fix
CF
-
Final Approach Course Fix
FF
-
Final Approach Fix
IF - Intermediate
Fix
MA
-
Missed Approach Point when not RW
SD - Step-down
Fix
RW - Runway
Threshold
OM - Outer
Marker
MM - Middle
Marker
IM
- Inner
Marker
BM
-
Back Course Marker
TD
-
Touchdown Fix when not RW
Unnamed Turnpoints and Intersections -
where no name has been assigned to a turnpoint or intersection,
the waypoint name in the navigation database is created by adding the distance of the point from the nearest
applicable navigation facility to the facility identifier, e.g. SEA77.
Temporary Waypoints -
place/bearing/distance (PBD), place/bearing-place/bearing (PBPB) and along track
waypoints are automatically named by adding a sequence number to the first three characters of the reference
waypoint, e.g. ANC01. Similarly, the names of waypoints entered in latitude/longitude are created by adding a
sequence number to the prefix WPT.
DME ARC Waypoints -
the waypoint name in the navigation database is created by adding the radial from the
DME station in degrees followed by the radius of the arc in nautical miles (represented by a letter: A = 1 nm, B =
2 nm, J = 10 nm, etc) to the prefix D, e.g. D173J.
Conditional Waypoints -
a conditional waypoint is used in the navigation database when a route leg does not
terminate at a defined latitude and longitude. Such legs include radar vectors, intercepts, and course or heading
legs, or a leg with a manual or an altitude termination. Conditional waypoint names are displayed in
parentheses as shown below. Conditional waypoints cannot be used for direct-to navigation, nor as references
for temporary waypoint creation, and cannot be copied into the scratchpad.
(INTC) -
Leg terminates at the interception of the next leg.
(3000) -
Leg terminates at the altitude shown. When a conditional altitude waypoint is active and where
a suitable altitude input is not available, a NEXT WPT prompt is displayed at LSK 6R of
PROGRESS 1/4 page, and a MANUAL WPT SEQUENCE alert message is displayed.
Operator action is required to sequence to the next waypoint.
(VECT) -
Leg is a radar vector. As described above, operator action is required to sequence to the next
waypoint.
