FOMS Menu 133 (Fuel/Payload Analysis Program)

This program allows the user to generate a report that indicates how much payload (or how many passengers) can be carried from one airport to another under various conditions in the course of a year. The program allows a variety of inputs for route, reserves, aircraft, cruise mode, wind component and temperature, etc., and then computes the required number of flight plans in background, and generates a report summarizing the results. NFP uses monthly historical winds in the calculations to produce the estimations in the report's results.

The only modes available are:

  • Screen

  • Hardcopy

  • Quit

Screen Mode




Choose which AIRAC cycle to use when generating a payload analysis

Note: The default AIRAC cycle is the current one as of 0800 of the next day.


Enter the airline code for the flight.


Enter the ICAO or IATA Code for the airport of origin.


Enter the ICAO or IATA Code for the destination airport.


Enter the Alternate airportMandatory field. 

Note: This field has similar functionality to the Alternate field in the Flight Plan, i.e., the default value is the first Alternate on file, you may use the <?> Search function to scroll through the various Alternates, or you may enter <NONE> or <ISLD>. 


Enter the FIN Number of the aircraft you want to be used in the calculations.


Enter the configuration of the aircraft, or use the <?> search function to scroll through the configurations.


Enter the desired cruise burn bias for the aircraft as a percentage.


There are a number of ways in which the route may be entered:

  • You may enter the City-Pair Route number <Rnn>

  • You may enter a fixed distance by making a numerical entry (the distance you enter must not be less than the Great Circle distance, however).

  • You may enter the distance as a percentage of the Great Circle by entering <Gnn> where nn is the percentage by which the Great Circle distance should be increased. Example: if you wanted to use Great Circle plus 15%, you would enter <G15>.


Enter the cruise profile you wish to have used.


This field will default to the Minimum Landing Fuel value stored in the Aircraft Characteristics record

Note: You may increase it, but you may not decrease it.


These fields will default to the Taxi Times for the Origin and Destination airports respectively. Note: You may edit them if you wish.


Enter any additional fuel that you wish to have included in the calculations.


The information included in FOMS Menu 131 can be imported to Excel as a CSV file. In order for a separate report to be created "Y" has to be entered under the "CSV" heading.

Conditions Table

When you enter information into this screen, you must input the information for all available month options (Jan-Dec, Summer-Winter, and each of the four quarters. You can press Enter to duplicate the same information for the active row from the previous row, or enter in each row individually for all 19 options. You cannot only provide a subsection of these 19 options.

For each month of the year, enter the appropriate values for:




Specify a month, season, years, or quartile to represent typical historical winds for your test flight. This field is only available if the flight is a test flight. 

Note: When Historical winds are used, the Wind component and ISA deviation fields are disabled. In addition, you are able to select the year range for the winds (current options are 3, 5, 10, 20, or 30 years) and define a percentile (1-99%).


Enter the MTOW to be used. The default value will be the Maximum Structural TOW from the Aircraft Characteristics record.


Enter the maximum landing weight for the aircraft.


Enter the number of passengers.


Enter the average passenger weight

Note: This will default to 214 for winter months, and 209 for summer, but it may be edited within the normal range for passenger weights.


Enter the fixed weight for cargo. The default value is 0.

Use <Ctrl E> to auto fill the PAYLD field with MAX.


Enter the aircraft payload, either a specific number in aircraft units or MAX.


Enter any explanatory notes you wish to be printed on the report.

Once you have made all of your entries, a confirmation prompt will appear on the Command Line. A positive response will initiate all of the flight plan calculations. When the calculation is completed, the results will be displayed on the screen. Press <Enter> to go through the report, or <Q> to quit.

When you quit the report, the program returns immediately to the conditions input table so that you can adjust the parameters and run another report. To exit from the program, use <Ctrl>-E to get to a confirmation prompt, and respond <Q>. This will return to the mode options prompt.

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.
