FOMS Menu 341 (Airways Route Update Program)

Modified on: Fri, 8 Mar, 2024 at 7:47 PM

This program allows the user access to the Airways data file, permitting airways data to be viewed and printed. These airways are used by the Minimum Time Track Airways program and all of the various Routes programs to ensure that any routes entered conform to the published airways.

The data is updated by NAVBLUE every 28 days in accordance with the AIRAC cycle.

The modes available are:

Add
Edit
Delete
Video

Hardcopy

Add Mode

Field	Description
AIRAC Cycle	Choose the AIRAC Cycle to use, see AIRAC Cycle for more information or press <ENTER> to view the current.
Name	Enter the airway designator (e.g., J503, V104), up to 5 characters.
Alias	Enter the airway alias name, up to 10 characters.
Waypoint/CC/T	Enter each waypoint in the airway, starting at the point at which the airway begins. The Country Code and Type need only be entered if there is ambiguity, otherwise they will be filled in automatically by the program.
Dir B/F	If the airway is designated as one-way, indicate the direction in which travel is permitted. Entering <F> for forward indicates that you may travel in the direction in which the waypoints are listed. Entering <B> for backwards on the other hand will indicate that travel is only permitted in the opposite direction to which the waypoints are listed.
FL	Enter the Flight Level code that applies to this leg of the Airway.
Altitude Min	Enter the minimum Flight Level for the airway. The default value is UNK for Unknown, which will be read by other related programs as 0, (i.e., Sea Level).
Altitude Max	Enter the maximum Flight Level for the airway. The default value is UNL for Unlimited.
G/C Trk Dis	These are display only fields, which will display the Great Circle track and distance between each pair of waypoints. They will, of course, only be filled in when the subsequent waypoint has been entered.
AWY Typ	ATS or RNAV route.
Codes	Enter any pertinent information for this waypoint as follows: S D: Advisory only F: Flight information only G 1: CDR airway type 1 2: CDR airway type 1 3: CDR airway type 1
Other codes	Indicate other: V = VHF E = Essential T = Transitional R = Non-essential U = Uncharted C = ATC Compulsory H = Holding fix
Leg Comment	Enter any relevant comments for the leg.
Comments	Enter any relevant comments for the airway.
Updated	This is a display only field which remains blank in Add mode. The current system date is written to the file when the record is saved to disk.
Source	Enter your initials to indicate the source of this information.

Edit Mode

Since there may be several airways in the world with the same name, the selection of an airway for editing may be a two step process, the first step being to identify which of the various airways of the given name it is that you want to edit.

When you enter Edit mode, you will be prompted for the entry of the airway name. If there is more than one airway by that name on file, then they will all be listed opposite an option number, showing the identifiers of all waypoints in each. In the event that there are more such airways than will fit on a single screen, (an indication that there are more to be seen will appear at the lower right of the screen) you may page to the next screen using the <Ctrl>-F function. You can return to the previous page by using the <Ctrl>-B function.

Enter the option number of the airway you wish to edit in order to switch to the editing screen. You may move around the waypoints table by using the up and down arrow keys to move from line to line, and the <Enter> key to move the cursor from field to field across a line. If the airway extends to more than one page, you may scroll back and forth from one page to the next using the <Ctrl>-F and <Ctrl>-B functions. The <Ctrl>-I and <Ctrl>-D functions may be used to insert or delete lines wherever necessary. When you are satisfied that you have completed all required editing, you can escape to a confirmation prompt by using <Ctrl>-E.

Delete Mode

Enter the name of the airway that you wish to delete. In the case that there is more than one airway on file with this name, the options screen will be displayed as per Edit mode. Enter the option number of the airway you wish to delete. The selected airway will be displayed, along with the Really DELETE? confirmation prompt.

Video Mode

Enter the name of the airway you wish to view. The program will retrieve the airway record, compute the track and distances between each waypoint, and display the airway on screen. You may then use the up and down arrow keys to view the next airway record on file. If an airway requires more than one page to be displayed, use <Ctrl>-F to view the subsequent pages.

Pressing <Enter> will return you to a blank screen and allow you to enter another airway. Entering <Q> will return you to a Command Line prompt.

Screen Mode

Field	Description
AIRAC Cycle	Choose the AIRAC Cycle to use, see AIRAC Cycle for more information or press <ENTER> to view the current.
Shard:	Enter the Shared Database in this field.
From/To Airway	Enter the range of airways that you want to include in the report.
Short, Long or Comment Report (S/L/C)?	Enter the format of report that you want. A Short report that shows only waypoints with left <, or right > symbols to indicate one-way restrictions where necessary. The Long report displays all of the information on file for each airway string. Comment format includes airway comments. Note: Because of the volume of track and distance calculations that must be made, it may take some time to display a Long listing if the selected airways are lengthy.

Hardcopy Mode

The Hardcopy mode works exactly like Screen mode, with the exception that the output is directed to the printer, rather than the screen.

Quit Mode

Entering <Q> from the Command Line will return the Next PROGRAM-NUMBER prompt so that you have the option of going directly to your next program if you know the menu number, or of returning to the previous menu if you simply press <Enter>.

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.
