FOMS Menu 135 (Direct Operating Costs Fields)

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 mode is used to add a new record to the DOC database.

ALC: Enter the airline code. This field is used to identify the airline code whose costs are represented in the database. In most cases the user can simply press enter in this field, which result in the field be defaulted to the customers primary ALC. In cases where customers are using the system to manage multiple ALCs, the user must enter the appropriate ALC.

FIN/Registration: Enter the FIN if known. This entry is optional. The associated registration will be displayed. The DOC database allows users to maintain a cost database for specific aircraft in their fleet stored by FIN number. If the user wishes to store the DOC for a specific FIN then he/she must enter the FIN number in this field. When a qualified FIN number is entered the registration, aircraft type, series, and engines data is auto populated using data from the aircraft characteristics record (ACR).

Aircraft Type/Series/Engine: The DOC database can be configured to store DOC data for a specific aircraft type. Users can enter the aircraft type directly into the field or use the FOMS search feature to search for the type they wish to use. Once a type has been entered the user will be then required to verify the series and engine combination. If the series and/or engines presented are not the desired values then the user can enter the values directly or use the FOMS search feature to find the values desired. This field is a mandatory field. Enter <?> to use the search function for the Series and Engine fields.

Currency Unit: This field is used to set the currency unit for the data being stored. When the data is used in the flight planning process the currency costs data will be converted to the customers local currency based on this entry. All supported currencies are shown in the following table (click to expand) .
