it; therefore, it would appear in the database as “GNB” at the second airport.

In general, the following codes are used to correspond to a waypoint type. When they are associated with an approach to a specific runway, 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.
