FOMS Menu 570 (AFTN FIR/UIR Addresses Program)

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.

This menu is maintained by NAVBLUE.

This program stores the AFTN addresses for Flight Information Regions and Upper Information Regions. The file is keyed on the four letter ICAO identification code in order to provide for worldwide operations without duplications. Periodic updating will be required as amendments are issued by ICAO or NOTAM.

The available modes are:

  • Video
  • Screen
  • Hardcopy
  • Quit


AIRAC Cycle / Cycle: Choose the AIRAC Cycle to use, see AIRAC Cycle for more information.

FIR Identifier: Enter the four letter ICAO identifier for the region. You will also be prompted to enter a Segment Identifier. This field is optional, and an identifier (a letter from A to Z) need only be entered if it there is a segment of the FIR whose parameters are different from those of the region as a whole. The identifier you use must conform to the Identifier assigned to the segment of the FIR in the FIR Boundary file.

IFPS: Indicate whether or not this FIR is part of the IFPS area, yes <Y> or no <N>.

EurRVSM: Indicate whether or not this FIR is part of the European RVSM area, yes <Y> or no <N>.

RNP5: Indicate whether an RNP5 check is required in this region, yes <Y> or no <N>.

Region Name: Enter the name of the region.

Centre Name: Enter the name of the primary Air Traffic Control Centre for the region.

Centre Phone: Enter the phone number for the primary ATC centre.

Flight Level Codes: In the first field, enter the two-character flight level code that will be used to determine the available flight levels for any off-airways flight in this FIR. Also enter the reverse flight level code in the second field.

HF Required: This field indicates if HF is required to operate in the FIR. If set to yes <Y>, the system looks at the aircraft's 10a items to ensure that item H is included. A warning is generated if HF is required and not present. Blank is the same as no <N>.

Use Leg Track: Indicate whether the flight plan is to determine the flight level to be used based on the direction of each individual leg of the route <Y>, or the overall direction of the flight from Origin to Destination <N>

Rpt Speed as Mach: Indicate whether speed is to be reported as Mach number or TAS in this FIR, by entering either <Y> or <N> respectively.

Oceanic Region Code:

Item 18 Wpt EETs: This allows you to specify whether or not to report waypoint EETs in Item 18, yes <Y> or no <N>.

RVSM Range: Enter the RVSM flight level and range.

CPDL/FANS above FL.: Set a Flight Level for advanced navigation requirements. When operating above the stated Flight Level, N-FP performs a Compute Check to confirm the aircraft is properly equipped for the navigation requirements.

PBCS Range: displays the Min / Max PBCS range

ADS-B Required: Is ADS-B required? -  yes <Y> or no <N>.

ADS-B Range: displays the Min / Max ADS-B flight level.

When a flight is routed through a FIR that has ADS-B required and the aircraft is not equipped, a warning is generated.  A warning is also generated if the flight level is outside the ADS-B range. Warning: Leg XX DCT XX have ADS-B equipment required between FL300 and FL400. Valid 10b codes the system will look for when creating a route: B1, B2, U1, U2, V1, V2.

Transition Level: Enter the transition level in feet.

Constant Mach: Indicate whether constant Mach flight is required, yes <Y> or no <N>.

Report Country Code: Enter the country code to be used in reports, such as Permits. Enter <--> for oceans. Next enter whether or not you want to override country codes found in this region with the report code previously entered: yes <Y> or no <N>.

ATC for Alternate: This allows the user to specify whether or not to file to ATC addresses for the alternate route, yes <Y> or no <N>.

Addr File Code: Enter the US Region filing code; <D> for US domestic, <B> for US domestic border, C for Canadian domestic, Z for China or leave the field blank. You can also apply a Departure/Overfly/Arrival codes to FIR addresses. Users can specify if an address should be used for Departure, Overfly or Arrival (default all). For example, if you only specify D, it will not be included if you are Arriving at or Overflying the FIR.

US HAR Ident: Enter the identifier of the FIR inside US HAR airspace.

Awy Max Climb/Descent: Enter whether or not to adhere to the maximum airway level in climb and descent, yes <Y> or no <N>.

TCAS Remark: this allows users to select to add the TCAS remarks to the ATC flight plan, yes <Y> or no <N>.

ICAO 2012: This allows the user to specify whether or not the FIR address accepts the ICAO 2012 format, yes <Y> or no <N>.

Item 19: This allows the user to specify whether or not the FIR address accepts the ICAO Item 19 format, yes <Y> or no <N>.

Max Dist: Enter the maximum direct leg distance.

Crossing: Enter whether or not FIR boundary crossings are allowed in direct legs, yes <Y>, no <N> or report cross<R>.

FIRS: Enter any specific FIRs for which the boundary constraint applies. This is optional. Up to ten FIRs can be entered.

Address - AFTN: Enter the 8-letter AFTN addresses for this region. Up to ten addresses may be entered.

Address - SITA: Enter the 8-letter SITA addresses for this region. Up to ten addresses may be entered.

The fields beside AFTN and SITA Addresses allow you to flag an AFTN or SITA address as D for domestic only or I for international only.

  • You can not set D or I for all the AFTN and SITA addresses.
  • Addresses flagged as Domestic will be used for Flights which are domestic
  • Addresses flagged as International will be used for flights which are International
  • Addresses not flagged as D or I will be used for both Domestic and International Flights
  • Flights can cross multiple FIRs but, for USA flights, the system picks addresses from the first FIR that is crossed. The system doesn't  look at the other FIRs.  
  • FOMS 170, the option FIR Addr Type can be set to A(AFTN) or S(SITA). If SITA is used, the SITA address is selected from the FIR which has both SITA and AFTN Address. The other type of address is selected if a valid preferred type address is not present.

Rpt AGCS Dept to: Enter the four letter identifier of the FIR to whom AGCS Dept are to be reported.

Comments: Enter any comments that you feel are pertinent.

FIR Effective Date: Enter the date on which this FIR will become active. If this field is left blank, then the FIR will be assumed active.

Expiry Date: Enter the date on which this FIR will cease to be active. If the field is left blank, then the system will assume that there is no termination date.

Updated: This is a display only field which will display the current system date in Add mode, and the date on which the record was last amended in any other mode.

Who: Enter your initials to indicate who was responsible for entry of this data.

Video Mode

This mode allows you to review any individual record on file, and to page through the file record by record. Enter the ICAO Identifier for the FIR you wish to view. If it is on file, it will be displayed on the screen, and you may then use the up and down arrow to move alphabetically through the file. If the identifier you entered could not be found, a Record Not Found - Press ENTER for NEXT AVAILABLE message will be displayed, and pressing <Enter> will bring up the next record in file.

Screen Mode

Selecting Screen mode form the Command Line will bring up the Report Selector screen.

Sort by FIR Ident. or Name (I/N)?: Indicate whether you want the report to be sorted by FIR Identifier, or by the Name of each Region.

From Ident. (e.g. ABCD): If you have selected to have the file sorted by Identifier, the cursor will be moved to this field for entry of the first FIR to be included in the report.

To Ident. (e.g. VWXY): Enter the identifier of the last FIR to be included in the report.

From FIR Name (e.g. A): If you have selected to have the file sorted by Name, the cursor will be moved to this field for entry of the first FIR to be included in the report.

To FIR Name (e.g. Z): Enter the name of the last FIR to be included in the report. Once your entries have been made, a confirmation prompt will appear on the Command Line. A positive response will generate the report to screen. Press <Enter> to page forward, or <Q> to quite from the report at any time.

Hardcopy Mode

This mode functions the same as the Screen mode, with the exception that the output is sent to the system printer. Also, since you can not abort a report in mid-stream, be cautious about requesting entire data file prints which could tie up the printer for lengthy periods.

Quit Mode

To exit the program, enter <Q> from the command line. You will then be given the option of entering the next program menu number directly, or of defaulting to the last used menu screen.
