Fuel Costs Fields

The table below is a description of each of the fields present in the Fuel Costs program.




Enter the ICAO, IATA, or FAA code for the airport. The remaining information on the entry line will be automatically filled in. If a fuel cost record already exists for a station, it will be displayed. To make changes to an existing record, use the Edit mode.


A unique, user-provided identifier for a user that defines value used in the fuel cost interface which allows you to designate different prices per city-pair. The unique identifier for the fuel cost can be added at any time before triggering the SAVE option. 

Note: A Fuel Cost record with a BLANK Identifier will be displayed as the default fuel cost for that station. 

If a Fuel Cost record with a BLANK Identifier is not found, the system uses the default fuel cost from the Airline Code Parameters until a different cost is selected.


Enter whether fuel is available at the station <Y> or <N>.


Used to address airports that charge different prices for different increments of fuel uplifted. Choose to indicate whether the cost is calculated incrementally or as a total. See Fuel Increments for more information.

Quantity Units 

Enter a quantity unit.


Enter a currency value.

Effective Date

Enter the date the information becomes effective.

Date Updated

This field is for display only and is automatically filled in with the current system date (ddmmyy).

Fuel Density

Enter fuel density, units, and volume.

Quantity Brackets (Bracket Minimum & Bracket Maximum)

The first value is automatically filled in as zero <0>, and the cursor is positioned on the upper limit field for the first volume range. Enter a value for the first range, or if there is only one range with no price break by volume purchased, press <Enter> and the program will insert the default value of 999999. Upon entering the domestic and bonded fuel prices (mentioned below), you may enter up to five more ranges; the upper limit for the previous range automatically becomes the lower limit for the next range. In any event, the upper limit for the last range has to be the default value.


Enter the unit price of fuel for the range. Up to six places of decimal may be used.


Enter the unit price for bonded fuel for the range. If there is no bonded price entered, the bonded price  by default will be the same as the price entered for domestic fuel.

Low Quantity Fuel Limit / Surcharge

These fields are called Low Qty and Surcharge on the FOMS 130 menu. They allow you to set a low quantity fuel limit and a surcharge on the fuel. If the ramp fuel is below the amount set, the fuel price increases by the amount in the Surcharge field. These values are taken into account in tankering calculations/ decisions.


Enter the name, phone number, etc., of the fuel supplier for your company at this airport.


Enter the name, phone number, contact, etc., for the agent who handles the fuel for your company at this station.


Enter any other pertinent information concerning fuel, prices, supplier, and/or handling at this station.

Once you have completed your entries, a confirmation prompt will appear, allowing you the option of saving, editing, or aborting the record.

Fuel Increments

  1. Click the Increments checkbox.

    • In order to add different pricing, the Increments box must be checked.

  1. Click the Bracket Maximum input field.

    • You will enter the quantity and fuel pricing. You will only need to fill out the Bracket Maximum, Domestic, and Bonded.

  1. Enter 9 into the 99999 field.

    • When you are finished, ensure the last row is "999999" to indicate that there are no additional costs.

  2. Once you select Save, the Bracket Minimum fields will auto populate based on your entries.


  • In standard billing, if we had 4000lbs of fuel, then the cost would be calculated as 4000 * 1.50.

  • In incremental billing, if we had 4000lbs of fuel, then the total cost would be calculated as (1000 * 2.00) + (3000*1.50).

Fuel Density by station

Enter a fuel density value, along with a weight unit and a volume unit per station in the Fuel Costs screen (webFOMS or FOMS 130). If you use the Fuel Costs menu you are setting a value for that station only.

Fuel Density by Default – All Stations

Enter a fuel density value, along with a weight unit and a volume unit per station in the Airline Code Parameters screen (webFOMS or FOMS 170). If you use the Airline Code Parameters menu you set a value for all stations.

Impact of Fuel Density On Uplift

If the volume of the tanks in the aircraft are specified, then the specific gravity can affect fuel uplift capabilities as a result of the variable density.

Main Parameter file default – All NFP customers

The default value for Fuel Density is set at 6.6611.

Invalid fuel density entries

The N-FP system does not allow invalid entries into either the Aircraft Characteristics or Airline Code parameter databases.

How does fuel density impact the flight plan?

Fuel density changes directly impact the fuel weight/tank capacity. The changes in these values may have an impact on the following:

  1. Extra fuel available when using max tanker (always be aware of max fuel uplift)

  2. Lower fuel density values may reduce the maximum fuel uplift weight, thus negatively impacting range and take-off weights

  3. Direct Operating Costs – fuel cost differences

Why change the fuel density?

Fuel density is impacted by the following factors:

  1. Field elevation

  2. Outside Air Temperature (OAT)

Expected flight plan results

Under normal circumstances, there will be no difference in fuel burns even when the fuel density value has been changed. The aircraft performance at weight/ISA/FL will remain unaffected by fuel density changes, however, the ability to tanker up to max fuel uplift (if structural weights allow) may be limited.

Note: The following descriptions represent the typical access and privileges given to users designated as Dispatch Managers/Supervisors. Users with Dispatcher privileges will have limited access to a subset of the screens presented.
