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 selects CI000 and entering 999 selects CI999 (if available). 

    • If they are not available, the closest CI value is chosen.

Opt CI
Indicate whether to use OPT CI in the Flight Plan. Options are yes <Y> or no <N>.
Min/Max Opt CI

Enter the minimum and maximum to control the optimum cost index. 

Note: The optimum cost index will not fall outside of this range.

Idle / Idle Factor
Enter an idle factor value, this value can display 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 the 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. 

Note: It does not affect the burn calculations.

Driftdown Penalty

Enter the penalty amount to apply to the driftdown calculations that determine what flight levels are valid. 

Note: 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 that the aircraft has been certified for flight.
Variable MTOW MIN/MAX

Enter the minimum and maximum variable take-off weight values to calculate a variable MTOW.

As the MTOW increases, the zero-fuel weight (ZFW) decreases in a linear fashion, thus fuel may be sacrificed for payload to an acceptable point. 

Note: Some aircraft allow the typical maximum take-off weight to be exceeded in order to allow for a larger payload. 

MZFW
Enter the maximum zero-fuel weight for which the aircraft has been certified for flight.
Variable ZFW MIN/MAX

Enter the minimum and maximum variable zero-fuel weights to calculate a variable ZFW.

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. 

Note: Some aircraft allow the typical zero fuel weight to be exceeded in order to allow for a larger payload. 

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 is 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 the departure airport and is used as the maximum fuel tank limit. 

Note: 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. 

Note: 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:


Hold Performance Available?

Dom/Intl Hold Field Entry

Dom/Intl Time Field Entry

Hold Calculation

Both Fuel and Time values are the Fixed values entered. No calculations are performed.

No

Any value


This condition is not permitted by the Aircraft Characteristics program. 

If there is no hold performance data in the Performance Profile Key, then the Fixed/Minimum Flag MUST be Fixed”.


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


Field

Description

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. 

Note: 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 calculates the desired tankerage and then subtract the Spare Tank amount. 


Example: Below you can see a difference in the XTR field (244215 lbs in the Flight Plan with Max Spare set to 10000 lbs vs 254215 lbs in the Flight Plan with Max Spare set to 0)


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

APU Rate

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

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.

  • If 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. 

Note: 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 is entered. 

Note: This fuel is included in the ETP required fuel for the selected scenario(s).

GND APU

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

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

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

This field is the 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.

Note: You can enter these values in the 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.


The Flight Plan format shows 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.



Example: Above image shows 20 minutes before and after refueling.

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

  • APU burns 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-FP 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 is complete, the aircraft starts burning off the overall fuel available for the flight. This means that APU Fuel After Refueling impacts the total ramp fuel which justifies the 117 LBS/KGS of APU fuel.

Note: Both APU fuels impact 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.

NOTAM Key

Enter a value used as an auxiliary key to identify the 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. Options are fixed <F> or blank (per hour).

Ballast

Enter the amount of standard ballast fuel. 

Note: This value populates the corresponding field in the Fuel group (Plan screen of N-FP UI).

Spare

Enter the weight of the spares.

Driftdown Method

Options are OffWeight reduceEscape 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 driftdown Escape Routes based on one engine out performance. 

  • If set to Off, NFP does not generate any driftdown Escape Routes. 

  • If set to Half, NFP generates driftdown 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.

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 is compliant with one or more of these specifications. The receiver type must be set in Aircraft Characteristics otherwise a compute error generates.

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 is to keep this checkbox deselected (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 automatically sets the algorithm to FDE. 

  • Leave the checkbox deselected (set to No), if you do not know which algorithm the GPS receiver is using. Note: This is a NAVBLUE recommendation.

  • 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 are set to use SA OFF. 

  • In some cases the GPS receiver manufacturer sets the receiver as SA aware. This means the GPS receiver uses 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. 

Note: This requires a configuration change, contact support for more details.

SBAS Status

Selecting this checkbox prompts the equipment to lead to an automatic result of "No Check Required".
