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.

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

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

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.

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.

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.

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. 

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. 

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.

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.

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.

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.

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 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 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.

Auto Weather Chart / WxChart Buffer FL

This field is used to add charts from a range of available FLs to the Flight Package. 

Example: A value of 50 with a cruise level of FL390 automatically adds charts FL340,FL390 and FL420. 

Note: This value overrides the value set in Airline Code Parameters screens.

Auto Weather Chart / WxChart Specific FL

This field adds a specific chart. 

Example: A value of 100 will automatically add a chart for FL100. 

Note: This value overrides 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

• A negative number adds less charts. 

Example: If the flight time was from 0900 to 1300, a buffer would extend the time range to 0600 to 1600. 

Note: This value overrides the value set in Airline Code Parameters screens.

Min Rwy Length

Enter the minimum runway length in feet. This is used to improve filtering for Suitable Escape Routes for airports.

Max Rwy Tail Wnd

Enter the maximum tailwind. 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. Refer to Max Tailwind for more information.

Req Runway Surface

Enter the required runway surface. Enter <H> for hard, <S> for soft, <W> for water or <U> for undefined. This is used to improve filtering for suitable escape routes for airports.

Default Runway

Enter a default runway to be used in the Route Builder screen when a specific aircraft is used. Options are <L> Longest Procedure, <M> Max Head Wind or <N> None.

Oxygen Endurance

Enter the aircraft's oxygen endurance in minutes.

The Oxygen Endurance is the amount of time that the descent in the event of depressurization must take place before the oxygen supply of the aircraft is depleted. 

Note: For more details on how Oxygen and Driftdown Escape Routes appear on the Flight Plan and how suitable airports are selected, refer to Escape Routes Requirements. You can have up to 4 FL and Time entries.

RTE QUAL

This field is used to allow the user to specify what equipment is onboard the aircraft. The route analysis process reads the data in this field and verifies that there is a match before using a particular route in the analysis process. See section 305 for information regarding this field in the route building process. 

• The valid entries are any text character. The field was designed to allow the user to define their own special equipment codes, thus the reason for allowing any text character to be entered. 

• Maximum number of entries is 4 per aircraft.

MORA Radius

Enter the value of the MORA Radius. 

• By default the radius is set to 5nm.

Atc Alias

Add this alias to the default ATC addresses.

Fp Alias

Add this alias to the default Flight Package addresses.

Talt Max Dist

This field specifies the maximum distance a takeoff alternate may be from the origin airport in the Flight Planning process. 

• The user may specify the distance or leave the field blank. 

  • In either case, if a takeoff alternate is used in the Flight Planning process for the specified aircraft and the distance to that alternate is in excess of the value contained in the field, the user receives an error message indicating the problem. See the Flight Plan section of the manual for specifics. 

  • If blank, the takeoff alternate distance defaults to 500 nautical miles for a two-engine aircraft and 1000 miles for three- and four-engine aircraft.
