The Waypoints and Facilities data file is a key navigation file for FOMS. The file contains information on more than 30,000 worldwide airway points, including data such as: identification, location, frequency, local magnetic variation, and VOR/NDB/Enroute/Terminal.
Given the number of changes that are made by the various regulatory bodies on a routine basis, it is highly recommended to keep this file updated at all times.
When called up, this program will display a blank file and a command line sequence for mode selection.
The modes available are:
To edit a record:
Select <E> from the Command Line prompt.
Enter the identifier of the waypoint you want to edit. If there is no ambiguity (i.e., if there is not more than one waypoint with that ID) then the record will be displayed. If there is some ambiguity, then the cursor will move to the Country Code field.
You may use the <?> Search function. If some ambiguity still exists after you have selected the Country Code, then you will be required to enter the Type as well.
Note: Since the Country Code and Type fields are the key part–they may not be edited. Should they require change, (ie. a VOR has been decommissioned, but a waypoint still exists at that location with the same ID), then you must delete the initial record, and add the new one.
To escape from Edit mode, you may enter <Ctrl>-E, and then make the appropriate response to the confirmation prompt.
As in the case of Edit mode, you must:
Enter the ID of the waypoint, followed by the Country Code and Type if required to resolve ambiguity.
The record will be displayed on screen, and you will be prompted to confirm that you do really want to delete it.
Note: As a precaution, the program will not allow the deletion of a waypoint that is used in any city-pair route, SID, STAR, ENTRY, or EXIT. In the background, a checking routine will be completed which will generate a usage report to the system printer if the waypoint is used at all. Only if no usage is found will the waypoint be removed from the data file. You must remove all usage of the waypoint (by editing the affected routes), and then re-delete the waypoint.
The Video mode allows the operator to review the file data for a single waypoint or facility, and to then alphabetically step through the data file, record by record.
When this mode is entered, a blank will be displayed and the prompt line will request the desired waypoint identification.
Resolve any ambiguity with the search function, or by entering country code and type.
The program will search the data file for the selected record and display its contents. If the record cannot be found, a warning will be sounded.
Pressing <Enter> will display the next available record (i.e., next record in alphabetical order).
Once the record has been displayed on the screen, you may use the up or down arrow keys to step alphabetically through the data file to view other records.
Should you pass either the top or bottom limits of the data file, you will be returned to the command line screen.
This mode allows the operator to review a range of waypoints. It is a quick and convenient way to examine which waypoints are in the data file.
Entering <S> from the command line will display this mode which will display a request for identification of the range you want to view.
The entire data file can be called by entering A-Z, or you may specify any portion of it, e.g., A - AC.
The prompt line will allow you to confirm your entries before proceeding.
Note: Up to 17 waypoints can be displayed on the screen at one time. If the range you have requested has more than 17 records, then pressing <Enter> will call up the next page.
Pressing <Enter> when the final page is on-screen will return you to the command line screen to select another mode.
The Quit option will allow you to escape from any intermediate page.
This mode allows you to produce a printout of the entire data file, or any portion of it.
The initial screen will request the range of waypoint files you want to have printed.
To print the entire data file simply press <Enter> twice. The default values of A to Z will automatically be inserted by the program.
For any other range, enter the waypoint identification codes for the first and last waypoints. Example: Entering YTR and YYZ will display all waypoints with identifiers that lie alphabetically between those two.
Note: A single letter response will produce a report on all waypoints with identification codes beginning with the selected letter. For example, entering from <C> to <C> will call up a report on all waypoints from CAAAAA to CZZZZZ inclusive.
Entering <Q> at the initial command line will return a prompt line which will allow you to enter the program number you want, or by pressing <Enter>, to return to the last used menu screen.
Note: The following descriptions represent the typical access and privileges afforded to users designated as Dispatch Managers/Supervisors. Users with dispatcher privileges will have limited access to a subset of the screens presented.
