WebFOMS Taxi and Circuit Times

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.

For an overview of the WebFOMS features see the Aircraft Characteristics screen. The features described there can be applied to all screens.


For instructions on how to make modifications on the WebFOMS screens, see Modify, View Aircraft Characteristics. It uses the Aircraft Characteristics as an example but can be applied to all WebFOMS screens.


Screen is the default view when you first go to a WebFOMS screen. When Screen is selected you can view all records that exist in the system.  Select the arrow in the first field of the WebFOMS screen to access the drop-down menu to view the list of available records.

Only items that exist in the database are shown in the drop-down list.

The purpose of the program is to allow the user to manage taxi and circuit times for a particular airport with a greater level of detail than is currently available via the airport database program. When these databases are populated for a particular airport then the flight planning system will use the information from these databases to determine the proper amount of taxi time or circuit time to use. If the flight plan being computed does not find information related to the airports of operation for that flight in these databases then it will use the default times found in the airport database. This program allows the user to define circuit and taxi times for specific times of day and further allows them to tailor the use of these times to a specific airline code or aircraft type.

The modes available are:






The add mode allows the user to build a tailored taxi time profile for an individual station. The following describes the valid entries for each field.

TYPE: Enter whether you want to add circuit times <C> or taxi times <T>. Circuit times and taxi times each have their own database.

Circuit time added does not apply to alternates.

ICAO: Enter a valid ICAO address that you wish to create a taxi time profile for. Entry of an IATA station code is acceptable; the system will convert this to the proper ICAO code.

ALC: Enter an Airline Code that you wish to have the profile applied to. If this field is left blank, the profile will be applied to all flights that operate at the airport specified.

EQUIP: Enter a valid equipment type (e.g., B737, B757). A search option is available by typing <?>. If equipment type is specified then the taxi time profile will only be applied when the specified equipment type is used on a flight that operates at the airport specified.

SERIES: Enter the series designation of the aircraft. A search option is available by typing <?>.

MIN: Next the user is required to enter the number of minutes to use as taxi time for a given time period. For example if the user wanted to show a taxi time of 12 minutes between the hours of 0000Z and 0400Z he would enter 12 in the MIN field on the 0000 line and then press Enter. When this is done you will notice that HH:MM column changes from 00:00 to 00:12 for all available time periods. If no other entries are made then the default taxi time for departures would be 12 for this city. In order to set an end time that the desired taxi time is applicable for the user must move the cursor to the desired end time line and enter a taxi value, which could be the standard taxi time for the city or a new taxi time for another period. The example above shows an example of a possible entry for Station CYYZ. The departure taxi time for CYYZ is set at 12 minutes between 0000 and 0400Z, from 0400Z to 1000Z the departure taxi time is set at 17 minutes. The rest of the day the taxi time is set at 10 minutes. The process described for entering taxi times is the same for the arrival section of the screen. As of this writing the system does not use arrival taxi times in any calculation so the necessity to maintain arrival taxi times is not vital.

Updated By: Place the initials of the person who added the record into this field. If skipped the system will automatically insert the user id of the person who was logged on at the time the change is accepted.

Date: The date field is used enter the date the record was added or changed and uses the normal FOMS date format.
