The following will provide details for each parameter currently residing in the FOMS 170 database on Page 3. Details include descriptions, available options, defaults, and system behavior once the parameter change has been saved.
ALC: This field represents the carrier’s three-letter airline code. Generally only one airline code is maintained on each system, however there is support for multiple airline codes should the user have the requirement to manage more than one airline code.
Unit (LBS or KGS): Options are L (LBS) or K (KGS). If set to L, passenger weights and fuel defaults are entered in LBS. If set to K, passenger weights and fuel defaults are entered in KGS. Weights entered here are the default weights displayed in NFP’s plan screen.
Dom Weight: Domestic Weight categorized by Adult, Male, Female, Child, Infant, Cabin Crew, Flight Crew and Baggage. Not all fields need to have data included.
Int Weight: International Weight categorized by Adult, Male, Female, Child, Infant, Cabin Crew, Flight Crew and Baggage. Not all fields need to have data included.
Allow Overbooked: Options are Y or N. If set to Y, NFP allows passenger counts greater than the default value in FOMS 220. If set to N, NFP does not allow passenger counts greater than the default value in FOMS 220 and will not allow a flight plan to be generated if over the default value. If blank, the same behavior as N occurs.
Check Zero Pax: Options are Y (yes), N (no), and E (error when zero). If set to Y, NFP provides a warning on compute if the passenger count is zero. If set to N, NFP does not provide a warning. If set to E, NFP does not allow a successful compute until a passenger count is entered.
Crew Weight By Assign: Options are Y (yes), or N (no). If set to Y, the checkbox for Based on Assignment on the Plan screen is automatically checked. If set to N, you must manually select the checkbox. Default when left blank is the same as N.
When enabled, crew members added to the crew list in NFP’s plan screen increase the BOW for the flight automatically based on the passenger weights set in FOMS 170. Removing crew from the list reduces the BOW accordingly.
Child Baggage: Include children’s baggage in weight calculations. Options are (Y)es, (N)o, Blank. Blank is N.
Infant Baggage: Include infant’s baggage in weight calculations. Options are (Y)es, (N)o, Blank. Blank renders the same result as N.
Max Rwy Tail Wind: Entry in this field is in knots per hour (wind speed). Enter the maximum tail wind value for your fleet. This value impacts automatic runway end selection for NFP features such as Max headwind and ALC Approach Minima. When set, NFP does not pick a runway for departure or arrival if the tail wind exceeds this value.
Curfew Check: Options are Y (yes)or N (no). If Y is entered, the curfew warning module is activated.
NFP provides a warning if a curfew is broken at origin or destination. Curfew times are stored in the FOMS 105 menu (Airports) or the FOMS 366 menu (Curfew times) databases. Curfew times entered in FOMS 366 overide the ones in FOMS 105.
If N is entered, the system will not alert you if curfews times have not been met. All curfew times entered in FOMS 105 or FOMS 366 are in local time.
If field is blank, curfew times will not be considered or warned against.
The options for the second field are Y and N. This option allows NFP to increase CI cruise profile or slow it down when OPT CI is used to avoid breaking a curfew. Y changes the OPT CI speed selection to meet the curfew times - a warning is displayed indicating that the best profile was used so that the curfew was not violated. N does not change OPT CI - a warning is displayed on the computed flight to indicate that arrival time breaks the curfew of the destination airport. The last two fields allow users to enter a start and end buffer time around the curfew set in FOMS 336, a warning message is displayed to indicate that curfew has been violated, the curfew and buffer times are shown.
The third field is to indicate a meet schedule cost index interval, which will look at those intervals to determine OPT CI. If left blank, the default is 50.
Apt Time Buffer: Enter the buffer time in minutes for the begin time and end time of curfews, runway and procedure validity times.
Fuel Prices Section
Default Fuel Prices (optional): This allows users to set default fuel prices that are considered when there are no prices entered in FOMS 130 for a station. Enter fuel prices for Domestic and International flights. When filled in, these costs are considered regardless of stations planned.
You must also decide the default currency and the unit of measure the fuel cost applies to (USG, UKG, LTR, KGS, LBS, or TON). These inputs reflect in the fuel costs shown on a per route basis.
Orig Use Multi Leg: Options are Y (yes) or N (no). If set to Y, NFP will look for a second leg with the same flight number and aircraft to confirm whether it is a Domestic or International flight. Once it knows, NFP applies the appropriate fuel cost based on that leg.
If set to N, NFP will not look ahead at any flight legs other than the one being planned. If field is blank, default is N.
Advise Tankering: Value entered as a percentage (%). Percentage value entered is minimum savings and impact NFP’s decision on whether tankering is beneficial or not. If auto tanker features are used (NextRamp or multi-leg), NFP does not auto-tanker if the total savings between tankering and not tankering is less than this percentage value. Default percentage is 10% when field is blank.
Warn ArrFob </>Ramp: Entries for both fields are in LBS or KGS (fuel weight). These two entries impact NFP’s NextRamp tanker feature. If used, NFP generates a post compute warning if the arrival FOB at the first destination meets criteria set in these fields based on the RAMP fuel requirements for the second leg.
Default Fuel Density: set the default fuel density for the entire ALC which can be displayed in LBS or KGS for the weight and the density can be set to USG, UKG or LIT.
Min Extra: Use these fields to add a minimum amount of extra fuel and specify what fuel types contribute if the sum of these values is lower than the minimum extra fuel, the difference is automatically added.
ID: Enter a unique identifier for the minimum fuel.
Fuel: Enter the minimum extra fuel required, if the sum of these values
is lower than the amount of fuel, the difference is automatically added.
Sum of: Select where to add the extra fuel. Options are: T-Tank, D-Add, H-Hold, A-Alt, C-Reserve, B-Ballast, N-Addn Hold, E-ETP, R-Reclear.
Additional Fuel: The value added in this field is automatically shown as additional fuel on all flight plans, regardless of the aircraft used.
Additional Fuel Amount: set in LBS/KGS, it is the total amount for the category that was created in the previous field
Optional: Y/N if the additional fuel is considered optional
Default: Y/N if the additional fuel is selected by default
Reason allows you to enter a default reason that will appear in the Additional Fuel dropdown on the Plan screen. You can add up to 10 reasons and you cannot duplicate a reason.
