Aircraft WebFOMS Screens
This topic provides you with an overview of the webFOMS screens that are in the Aircraft group on the NFP database tab on the Maintenance screen.
Aircraft Characteristics - General
The Aircraft Characteristics Database is used to store data on each aircraft in the airline’s fleet. An aircraft record must be entered in the file before a flight can be run using that aircraft. Given no more than the airline’s identification number (or letters) for a particular aircraft (sometimes referred to as FIN, tail, wheel, hull or airframe number), other programs in the system can access this data file and obtain information such as aircraft type, operating weights, SELCAL code, and fuel consumption deviations.
The General tab is used to check or enter the key weights of the aircraft. The exception is the OEW weight. OEW is located in the Others tab. This includes structural weights, fuel capacity, MLF, MLW, HOLD, etc.
Aircraft Characteristics - Performance
The Performance tab is used to set the default profile for the aircraft (LRC, CI030, MCT, etc.), set ETOPS parameters if applicable, specify RAIM settings, oxygen and endurance time. If you use TEL (telvent) data you can specify flight hazard values. This is also where you can set fuel bias percentages (1.02 = a bias of 2%).
Aircraft Characteristics - Atc Items
The Atc Items tab affects the content of the
FPL message sent to ATC. It is very important that you enter the correct ITEM 10 codes and corresponding PBN codes so the equipment
onboard can be correctly identified by ATC.
In the event that a piece of navigational equipment is U/S temporarily, you can override the ITEM 10 codes for a specific flight on the plan screen (little green arrow next to the aircraft registration).
Aircraft Characteristics - Report
The Report tab affects the flight package and
the ATC FPL slightly by setting whether the FPL is filed by flight number or REG.
This is where aircraft specific ACARS details are stored and where you must enable ACARS before it can be used (Equip field).
Setup to enable ACARS functionality must be performed by NAVBLUE Support.
Aircraft Characteristics - Others
The Others tab is where the OEW is set, where ACN & PCN values are set and APU defaults are set. Also driftdown settings are located here. Comments can be entered as well.
MEL / CDL Assignments
Use this program to assign outstanding maintenance (MEL/CDL) items against a particular airframe so that whenever that aircraft is used by the Flight Plan program, the list with its corresponding descriptions will be displayed for the dispatcher. When an aircraft is scheduled for a flight, the dispatcher can review the list to see if there are any operational restrictions that may have an impact on flight planning. For instance, some defects may impose a limit on the maximum altitude to which the aircraft may be flown, and this should, of course, prompt the dispatcher to cap the flight level used by the Flight Plan..
MEL / CDL Dictionary
Use this program to create and maintain a data file of Minimum Equipment List (MEL) and Configuration Deviation List (CDL) code numbers and their corresponding explanations and descriptions. The descriptions are limited to either 50 or 60 characters depending on the classification of the item: operational or non-operational respectively. The descriptions are not intended to be definitive; the objective is to make them detailed enough to alert dispatchers to any restrictions that may affect flight planning.
Use this program to define exactly how the Equal Time Point fuel requirements are calculated. Only records that exist in the database are shown in the drop-down list.
The copy function is only available through the webFOMS screen.
Use this program to group one to six different ETP calculation scenarios together as a single policy. This can be assigned to an individual aircraft. The ETP calculation routine within the flight plan program is capable of calculating the fuel requirements according to six different scenarios for each pair of ETP alternates. This program allows control over the scenarios that are used for any given aircraft. The copy function is only available through the webFOMS screen.
Direct Operating Costs
This program is used to store and manage direct operating costs (DOC) associated with the operation of their aircraft. The data stored in this database is used by the flight planning system to in determining
the optimized cost flight plan and routing.
You can use the Apply To drop down list/entry to apply the Block Delay Cost in different ways:
■ Entire Flight - When selected, the cost applies to the entire flight, from departure to arrival.
■ Time Above Scheduled
Block - When selected, the cost applies only to the flight time in addition to what was originally scheduled. For example, if a flight is delayed by a half hour due to winds, the
charge will only apply to that half hour.
