CI Adjust: This field is intended for specific use for A330 planning when using Opt CI. It compensates for optimum cost index results vs FMS entry. Valid entries are between -999 and 999. Entering -999 will select CI000 and entering 999 will select CI999 (if available). If they are not available, the closest CI value will be chosen.

Opt CI: Indicate whether to use OPT CI in the flight plan: yes <Y> or no <N>.

Min/Max Opt CI: Enter the minimum and maximum to control the optimum cost index. The optimum cost index will not fall outside of this range.

Idle / Idle Factor: Enter an idle factor value, this value can displayed on the Flight Plan, but has no effect on the calculation.

Min Cruise Dist: Enter a minimum cruise distance. The default value is 0 (zero). If non-zero, the flight plan may not climb as high to result in a longer cruise distance. The system may prefer lower flight levels if cruise distance of the flight does not adhere to the minimum cruise distance. This will not guarantee that the minimum distance will be satisfied because of minimum flight level restrictions.

Enr Climb Penalty: Enter the penalty amount to apply to the enroute climb calculations that determine what flight levels are valid. It does not affect the burn calculations.

Driftdown Penalty: Enter the penalty amount to apply to the drift down calculations that determine what flight levels are valid. It does not affect the burn calculations.

RAMP: Enter the maximum allowable weight of the aircraft prior to taxi.

MTOW: Enter the maximum take-off weight to that this aircraft has been certified for flight.

Variable MTOW MIN/MAX: Some aircraft allow the typical maximum take-off weight to be exceeded in order to allow for a larger payload. As the MTOW is increased, the zero-fuel weight (ZFW) decreases in a linear fashion, thus fuel may be sacrificed for payload to an acceptable point. Enter the minimum and maximum variable take-off weight values to calculate a variable MTOW.

MZFW: Enter the maximum zero-fuel weight for which this aircraft has been certified for flight.

Variable ZFW MIN/MAX: Some aircraft allow the typical zero fuel weight to be exceeded in order to allow for a larger payload. As the ZFW is increased, the maximum take-off weight (MTOW) decreases in a linear fashion, thus fuel may be sacrificed for payload to an acceptable point. Enter the minimum and maximum variable zero-fuel weights to calculate a variable ZFW.

MaxTaxi@VMTOW: This field allows you to specify the maximum taxi fuel if you are using the variable Min and Max MZFW fields. This additional restriction limits MTOW if extra taxi fuel is used as the MTOW value is lowered by the value entered.

ADJ BOW: Enter the adjusted basic operational weight of the aircraft.

Min ZFW: Enter the minimum zero fuel weight.

Note: If the calculated zero fuel weight is below the MIN ZFW then BALLAST fuel will be automatically added. Typically, this is a parameter to enable, where by default ballast is not part of ZFW. Be mindful that the ballast could reduce your max payload if limited by MZFW. The system displays a warning message if ballast fuel was added to meet MIN ZFW.

Min Flt Wgt: Enter the minimum flight weight to automatically add to ballast fuel.

MaxFuel Wgt / Max Fuel Weight: Enter the maximum weight of fuel that may be boarded with all tanks full.

Vol / Max Fuel Volume: Enter the maximum fuel volume, the value will be converted to KG based on the fuel density of departure airport and will be used as the maximum fuel tank limit. Max fuel uplift weight(kg/lb) is ignored if the volume amount is specified.

Min Disp: Enter the minimum amount of fuel that must be on the aircraft for it to be flown, according to your Company policy. There is no point in making this less than Min Landing Fuel.

Min Alt/Min Burn: Enter the minimum amount of fuel to burn to get to the alternate.

Dom/Intl Hold Fuel/Time:

These entries enable the user to control exactly how the hold fuel is to be calculated whether or not hold performance data is available. If hold performance is available (and part of the selected Performance Profile Key), then these fields may be used to define minimum values for holding fuel. In most cases, however, if holding performance data is available, then these fields may be left blank. In the event that entries are made, they will be interpreted by the flight plan in accordance with the following table:

In the case where the hold time value has been entered as 0, the hold time will be calculated using the following parameters:

ISA = 0

Weight = EZFW + Min Landing Fuel

Elevation = Alternate airport elevation + 1500feet (If alternate = NONE, use destination airport elevation.)

Min Desc: Enter the minimum descent fuel amount.

ENR APU: Enter the auxiliary power unit fuel per hour rate for the main route.

Rec MLF: Enter the recommended landing fuel amount.

Dest Elev: These fields are to permit three different ranges of airport elevation for which different maximum landing weights may apply, to be specified. They should be left blank if not required for the subject aircraft.

Max-Landing Reg: Enter the regular maximum landing weight.

Max-Landing Tank: Enter the maximum tankering landing weight, or press <Enter> for the default.

Reclear Pad: Enter the default value for Planned Redispatch Fuel Padding.

Spare Tank: This field only applies when using the Max, OPT, or Table tankering options. Enter a weight value to reduce tankerage and leave room for last minute payload addition. The system will calculate the desired tankerage and then subtract the Spare Tank amount. In the example below, you can see a difference in the XTR field (244215lb in the flight plan with Max Spare set to 10000lb vs 254215lb in the flight plan with Max Spare set to 0)

Please Note: The Spare Tank function takes into account the payload available before reaching MZFW, and will decrease the buffer where restricting the uplift would not be beneficial. (e.g. 10000lb Spare Tank set and no MTOW constraints, but only 3000lb payload available before reaching MZFW. The system will decrease the Spare Tank value to 3000lb and upload 7000lb of fuel instead).

APU Rate: Enter the ETP auxiliary power unit burn rate in units per hour.

Ground APU:

ENR APU: Auxiliary power unit fuel per hour. The amount of fuel burned while the aircraft is airborne. The Fuel value is entered in LBS/KGS per hour. Fuel value entered here is multiplied by the flight’s EET and included in the total burn for the flight.

ETP APU: Equal Time Point APU fuel, included in the ETP scenario.

When set to Calculate in the Method field in the ETP Scenarios database, the N-FP system multiples the ETP APU fuel entry (LBS/KGS) from the Aircraft Characteristics database and multiplies it by the EET between the ETP point and the ETP alternates. This fuel is not included in the ETP required fuel for the selected scenario(s).

If set to Fixed, a Burn value in LBS/KGS per hour will have to be entered. This fuel will be included in the ETP required fuel for the selected scenario(s).

Gnd APU: Ground APU, fuel burned while aircraft is on the ground or at the gate.

Ground APU fuel can be displayed on a separate line in the format’s fuel burn block under required fuel as it is expected to be used prior to takeoff.

In this example, the Gnd APU is 440 LBS/KGS per hour. Notice the APU line item under the minimum fuel required line.

Gnd APU Time Before and After: Amount of time the auxiliary power unit is running on the ground before and after refueling.

Values entered are taken into consideration for multi-leg tankering calculations to determine how much fuel is required.

The flight plan format will show an increase in the taxi out fuel if the Ground APU time between refuel and Taxi Out is greater than zero. These fields are displayed on the flight plan with Taxi fuel parameters.

This example shows 20 minutes before and after refueling.

APU will burn for 20 minutes before refueling which is 350 per hour ÷ 3 = 117 LBS/KGS

APU will burn for 20 minutes after refueling which is 350 per hour ÷ 3 = 117 LBS/KGS

The flight plan format shows APU fuel below:


 

Notice that the APU fuel value is 117 and not 234. This is because the N-Flight Planning system considers APU Fuel Before Refueling as the same as destination taxi fuel. The aircraft lands with fuel remaining, some of it is burned off taxiing to the ramp/gate and waits until refueling begins. If the sum of both APU and taxi fuels were more than the minimum landing fuel, then more fuel would be required at takeoff to compensate for this. This is why the second 117 was not used.

The N-Flight Planning system considers APU Fuel After Refueling as the same as origin taxi fuel. Once refueling has finished, the aircraft starts burning off the overall fuel available for the flight.  This means that APU Fuel After Refueling has an impact on the total ramp fuel which justifies the 117 LBS/KGS of APU fuel.

Both APU fuels will have an impact on the required fuel for the multi-leg tanker if the aircraft is performing a multi leg tanker flight and does not refuel at the destination.

You can enter these values in Airline Code Parameters database for all aircraft. Values entered in the Aircraft Characteristics database screen override values set in the Airline Code Parameters database. Also you can set in fields in the Input Defaults screen. Values set in the Input Defaults screen override values set in the Airline Code Parameters and Aircraft Characteristics database.

NOTAM Key: Enter a value used as an auxiliary key to identify this particular aircraft for the purposes of NOTAM Filtering.

Taxi: Enter the taxi fuel burn rate in units per hour.

Taxi Fuel Rate: Enter the taxi fuel rate: fixed <F> or per hour (blank).

Ballast: Enter the amount of standard ballast fuel. This value will populate the corresponding field in the Fuel group (Plan screen of the NFP UI).

Spare: Enter the weight of the spares.

Driftdown Method: Options are Off, Weight reduce, Escape Routes, and Automatic. If set to Off, NFP does not provide any escape routes. If set to Weight Reduce, NFP penalizes aircraft weight to meet MORA requirements (Method 1). If set to Escape Routes, NFP generates escape routes (O2 or drift down – Method 2) if MORA value is higher than 10,000 feet along the route of flight. If set to Automatic, NFP generates escape routes and if unable to do so safely, reduces aircraft weight as per Method 1.

Check Driftdown: Options are Yes or No. If set to Yes, NFP checks MORA for all routes including alternates and reclear but not takeoff alternate. If set to No, NFP only checks MORA for the main route.

Error on Driftdown: Options are Yes or No. If set to Yes, NFP aborts a compute if a MORA check fails. If set to No, NFP only provides a warning.

Driftdown Engines: Options are 1EO (one engine out), Off (off), Half (half engines). If set to 1EO, NFP generates drift down escape routes based on one engine out performance. If set to Off, NFP does not generate any drift down escape routes. If set to Half, NFP generates drift down escape routes based on the number of engines divided by 2. For 3 engine aircraft, H = 2 engines out. If blank, the same behavior as Off occurs.

Advisory Fuel: Enter the amount of advisory fuel.

Advisory Reason: Enter an advisory fuel reason.

Route IFR (Instrument Flight Rules) Fuel: Enter the amount of route IFR fuel.

Route IFR (Instrument Flight Rules) Time: Enter the route IFR time.

Alt IFR (Instrument Flight Rules) Fuel: Enter the amount of alternate IFR fuel.

Alt IFR (Instrument Flight Rules) Time: Enter the alternate IFR time.

Max FL: This field is used to set the maximum flight level the aircraft is capable of operating at. Most often it is set to the certified limit of the aircraft; if it is left blank the system will flight plan based on all available performance data, which in some cases could exceed service ceilings.

NAT MACH: Enter the fixed Mach number to be used for NAT tracks.

ATC ALC: Enter the airline code to be used for ATC filing.

PAX: Enter the maximum number of passenger seats available.

CRW: Enter the total number of cockpit crew and flight attendants (if applicable) that are carried for normal operations.

Receiver Type: The ADSB check and RAIM calculation supports GPS specifications TCO C-129a, TCO C-145a, TCO C-146a and TCO C-196a  receivers. The GPS receiver in the aircraft will be compliant with one or more of these specifications. The receiver type must be set in Aircraft Characteristics or else a compute error will be generated.

Baro. Aiding: The GPS receiver in the aircraft may have a physical connection to the Baro-altimeter or the FMS. If it does, select this checkbox. If you do not know if the GPS receiver is “baro-aided”, then the safe option would be to keep this checkbox de-selected (No).

FDE Algorithm: Options are Yes, No or E (enroute only) The service supports both FD (Fault Detection) and FDE (Fault Detection and Exclusion) RAIM algorithms. Some airspaces, routes, or approaches may mandate that FDE be used for the RAIM prediction. Selecting TCO-C145a or TCO-C146a receivers will automatically set the algorithm to FDE. If you do not know which algorithm the GPS receiver is using, NAVBLUE recommends that you keep this checkbox de-selected. When set to E (enroute only), the FDE Algorithm is used only for the enroute portion of the flight.

SA Status: Selective Availability - Most modern GPS receivers will be set to use SA OFF. In some cases the GPS receiver manufacturer will the receiver is SA aware. This means the GPS receiver will use the SA status of the GPS constellation - SA OFF. If SA Status is not specified the system assumes the setting is SA ON.

RNP AR: If checked, an RNP AR check is performed provided that the aircraft is configured for checks and the airport data has been entered for landing airports only in a new Airport Configuration WebFOMS screen. The check occurs during RAIM validation. This requires a configuration change, contact support for more details.

SBAS Status: Selecting this check box prompts the equipment to lead to an automatic result of "No Check Required".

Sched: Enter the default schedule type to be used. If this field is populated, that value is used. If not, the value from FOMS Menu 170 is used.

EQUIP-TCAS/ACAS: Indicate whether the aircraft is TCAS-equipped <TCAS>, TCASII equipped <TCASII>, ACAS-equipped <ACAS>, or blank - none .

TCAS (webFOMS): Indicate whether the aircraft is TCAS-equipped <T>, TCASII equipped <2>, ACAS-equipped <A>, or none <N>.

OEW: Enter the dry empty weight of the aircraft. Eighteen different values may be entered to reflect up to nine different configurations of the aircraft that can be selected in the flight plan screen. In order to support up to nine values and still maintain one screen; paging functionality is added to the OEW field. This means that once a user has entered his third value and selects enter the OEW field will go blank and the cursor will be placed in the first blank field of the OEW section. The first three weights have been saved to the record at this point. Now either the user may enter additional OEW weights or he may select enter. If the user wishes to input additional weights, he can do so at this point. After the next three weights are entered and the user selects enter, the fields will again be blanked out indicating that the weights have been written to the record. Again, the user may now enter additional weights or select enter. Selecting enter will move the cursor to the MZFW field and the original three OEW weights will be displayed. Only one entry is mandatory.

Auto Weather Chart / WxChart Buffer FL: use this field to add charts from a range of available FLs to the Flight Package. For example, a value of 50 with a cruise level of FL390 automatically adds charts FL340,FL390 and FL420. This value will override the value set in airline code parameters screens.

Auto Weather Chart / WxChart Specific FL: use this field to add a specific chart. For example, a value of 100 will automatically add a chart for FL100. This value will override the value set in airline code parameters screens.

Auto Weather Chart / WxChart Buffer Time: This buffer allows you to decrease or extend the time range when auto-selecting weather charts to add to the flight package. A positive number adds more charts and a negative number adds less charts. For example if the flight time was from 0900 to 1300, a buffer would extend the time range to 0600 to 1600. This value will override the value set in airline code parameters screens. This value will override the value set in airline code parameters screens.
