Field

Description

RNP Check

Two fields: 

• Perform RNP Check flight legs? 

  • Options Y, N or Error 

• Always check airport procedure RNP values when building routes? 

  • Options Y or N.

Zero RcPad Inft

When the flight plan is set to “In Flight,” set reclear pad to zero? Options: Y or N.

CoNtm Checks

Two fields:

• Compute warning if a Company NOTAM is modified within the number of hours entered.

• Compute warning if a Company NOTAM is due to expire within the number of hours entered.

Mel Checks

This parameter consists of 4 fields:

• First field options are Y or N. 

  • If set to Y, NFP generates an error if an MEL restriction has been broken based on the penalties for that MEL. 

  • If set to N, NFP generates a warning and allows a successful compute.  

  • If blank, the same behavior as Y occurs.

• Second field options are W (Warning), E (Error), or N (No check). Based on selection, NFP verifies if an MEL is expired. If it is, NFP generates either a warning, abort compute, or ignores the expired MEL.

• Third field options are D (Departure) or A (Arrival). 

  • If set to D, NFP performs an MEL expiry check based on the flight’s ETD. 

  • If set to A, NFP performs an MEL expiry check based on the flight’s ETA.

• Fourth field entry is in hours. Enter the number of hours you would like NFP to do an MEL expiry check after ETD or ETA based on the settings in the third field (Departure/Arrival + X hours). This buffer allows NFP to verify whether an MEL expires within the specified period.

Auto Reclr Fuel

Options are Y or N. 

• If set to Y, NFP automatically adds extra fuel for reclear requirements without forcing you to do so. 

• If set to N, NFP generates an error, forcing you to manually add fuel to meet the reclear requirements. 

• If blank, the same behavior as Y occurs.

Auto Arrv Fuel

Options are R (required) or T (tanker). 

• If set to R, additional fuel is added to meet a fixed arrival fuel value and is included as required fuel within the fuel block. 

• If set to T, additional fuel is added to meet a fixed arrival fuel value and is included as extra/tanker fuel.  There is no need for a format change if the flight plan format accommodates both the required and extra fuel values.

Auto Dept Fuel

Options are R (required) or T (tanker). If set to R, additional fuel is added to meet a fixed departure fuel value and is included as required fuel within the fuel block. If set to T, additional fuel is added to meet a fixed departure fuel value and is included as extra/tanker fuel.  There is no need for a format change if the flight plan format accommodates both the required and extra fuel values.

Ground APU Time

Two fields: 

• The default amount of time (in minutes) that the APU is running on the ground before refueling.

• The default amount of time (in minutes) that the APU is running on the ground after refueling.

Leg Max

Check the maximum time and distance per leg. Options are No, Error or Warn. 

• If it is left blank, it will default to No. 

• If Error or Warn is selected, you must set the maximum distance in nautical miles per leg and maximum time in minutes per leg.

Default EnrWx

Options are Y or N. 

• If set to Y, NFP automatically provides weather and NOTAM information for stations meeting suitability criteria for the aircraft. Note: This additional information is included in the flight package. 

Interval/Radius

Enroute stations are selected based on the interval (distance between points on route in NM), and the radius (maximum distance from points on route in NM). Options are Y or N. 

• If set to Y, as it is in this example, NFP finds a point on the route of flight every 200NM and then searches within 100NM of those points for stations meeting the suitability criteria. The weather and NOTAMS for those suitable stations are added to the flight package.

• If set to N, NFP does not provide any Enroute weather or NOTAMS. 

• If blank, the same behavior as N occurs.

RoundUp Fuel 

When this option is selected, the system will automatically round up both ground fuel (i.e. taxi) and the total ramp fuel to even hundreds of pounds/kilograms. Options are Yes, No, and Blank. 

Note: Blank is the same as no.

TakeOff Alt Warn

Options are E (error), W (warning), and L (error except MLW). 

• If set to E, NFP generates an error if there is a problem with the selected takeoff alternate. 

• If set to W, NFP allows the compute to occur but generates a warning. 

• If set to L, NFP generates an error unless the problem is due to exceeding the MLW value at the takeoff alternate.

AIRAC Offset

Enter + or -, followed by a time value in minutes, to establish an offset from 00Z where the next AIRAC cycle becomes effective.

Island Hold Pol (reserve policy)

Policy options are currently 01 through 15 and descriptions of each can be found in the Airline Code Parameters in the NFP Database tab. 

Ballast in Zfw

Options are Y or N. 

• If set to Y, NFP includes ballast fuel as part of the zero fuel weight. 

• If set to N, NFP does not include ballast fuel as part of the zero fuel weight  

• If blank, the same behavior as Y occurs.

Rules Enabled

Options are Y, R (RAD only), A (include All), N, or E (Error). You can manually change these options, but this parameter determines what the default setting is. 

• If set to Y, NFP provides a warning if a rule(s) impacts the route. 

• If set to R, NFP only considers the RAD document(s) when generating a route. 

• If set to A, all rules will be considered. 

• If set to N, the rules are ignored and no warning/error is generated. 

• If set to E, NFP generates an error if a rule(s) impacts the route.  

• If blank, the same behavior as Y occurs.

Constant Mach

Options are Y or N.

• If set to Y, NFP ensures a constant Mach speed is flown through designated FIRs as specified in FOMS 570. 

• If set to N, NFP does consider flying constant Mach speeds through designated FIRs.  

• If blank, the same behavior as Y occurs.

Note: NAT tracks are always designated as constant Mach.

Default Max Pyld

Options are Y or N. 

• If set to Y,  the Payload field on Plan Screen defaults to Maximum. 

• If set to N, payload field remains blank (fixed payload). 

• If blank, the same behavior as N occurs.

Max Pay Cmp

Max Payload Compare is used to instruct N-Flight Planning to always calculate max payload, even if a payload has been specified. This is an information-only value that yields a maximum-allowable zero-fuel weight that may be of use on the flight plan or certain load planning integrations. 

1. Select Y or N to enable max payload compare. 

2. Use the next field to select the Opt method for payload compare, Least <F>uel, <C>ost or <T>ime. 

3. The next field is used to select a performance profile to use for max payload compare. 

Note: Max Payload Compare can also be used for alerting purposes using the Weight Check field. This increases compute times and should only be used if it is known to be required.

Max PayTolerance (maximum payload or tanker)

This parameter setting impacts the payload and tankerage fuel calculations when maximum is used for both features.

The default value if blank is 200 (LBS or KGS – you choose LBS or KGS in the Aircraft Characteristics Screens).

Options O, T, L, M, or N.

• If set to O, tanker default is Optimal

• If set to T, tanker default is Table

• If set to L, tanker default is Next Ramp

• If set to M, tanker default is Optimal Multi-Leg tanker

• If set to N, tanker field remains blank as a standard. Users can still manually select a tanker option in the Plan screen. 

Use TOD for Hold

Options are Yes or No.

When Yes is selected the hold calculation uses Top Of Descent fuel flow instead of hold performance when necessary for the primary hold.

WGS84 Fuel Burns

Options are Y and N. 

• If set to Y, NFP observes the WGS84 model for carbon emissions. 

• If set to N, NFP observes the sphere model. 

Note: Both options do not affect displayed distances.

Avoid NAT track FLs

Options are Y or N. 

• If set to Y, NFP does not allow a route to fly at the same flight level as a NAT track if crossing it. FOMS 330 shows available flight levels for the NATS. 

• If set to N, NFP does allow a route to cross a NAT track at the same flight level. 

• If blank, the same behavior as N occurs.

MLF Override (minimum landing fuel)

Options are Y, N,or I (in-flight). 

• If set to Y, you can lower an MLF value that overrides the default weight entered in FOMS 220 for both standard and in-flight plans. 

• If set to N, NFP does not allow an override. 

• If set to I, the can only override the MLF value on an in-flight plan. 

• If blank, the same behavior as N occurs.

Respect AwyMin

Enforce airway minimums? 

• Options are Y, N, or E (error). 

  • If set to Y, NFP provides flight levels above the minimum flight levels for the airways as per FOMS 341.

  • If set to N, NFP does not respect the minimum flight levels. 

  • If set to E, NFP generates an error if a route is planned below airway minimum flight levels.

Respect AwyMax

• If set to Y, NFP ensures that airway maximum flight levels are not exceeded as per FOMS 341. 

• If set to N, NFP does not respect airway maximum flight levels. 

• If set to E, NFP generates an error if a route is planned above airway maximum flight levels.

Apt DCT Split Dist

When a distance value in NM is entered, NFP creates pseudo waypoints at the appropriate distance/interval that appear in the nav log for segments origin –TOC and TOD – destination. This provides the aircrew with valuable climb and descent information between pseudo waypoints that would normally not be available.

These pseudo waypoints appear in the route log as pure waypoints (11 character lat/longs). 

Note: If blank, the feature is not enabled.

Org/Dst Taxi

Enter a default origin and destination taxi time in minutes. Note: This overrides the airport taxi time.

Org/Dst Circuit

 Enter a default origin and destination circuit time in minutes.

Circuit Method Org

This parameter consists of two fields:

• Org: options are C (calculated) or B (burn bias) for origin circuit time. 

  • If set to C, NFP moves the TOC point closer to the origin and adjusts burns accordingly. 

  • If set to B, only the burns are adjusted based on circuit time.

• Dst: options are C (calculated) or B (burn bias) for destination circuit time. 

  • If set to C, NFP moves the TOD point closer to the destination and adjusts burns accordingly. 

  • If set to B, only the burns are adjusted based on circuit time.

Default RwyInt Wx (Aerodata integration)

Options are Y or N. 

• If set to Y or left blank, the RWA box displays weather data from NFP when the RWA window is opened. 

• If set to N, all RWA fields are blank and can be filled in manually. You can leave the fields empty and send a runway request to Aerodata. Aerodata will populate the fields with their data when a runway request is sent. 

• If set to N and you select the Default Wx button in the Runway Analysis dialog, the weather data source is from Aerodata.

RwyInt Pres. Unit choose which runway integration pressure unit to display. 

• Options are M for millibar or I for inches of Mercury. 

• If the field is blank the NFP system uses the same unit of measurement used in the original TAF/METAR.

Default Runways

Options are L (Longest procedure), M (Max headwind), B (Best route) or N (None). 

NFP Departure and Arrival Runway fields default to whichever is set in this field. 

• To enable the automatic runway selection based on valid TAF, this parameter must be set to M or B. 

• If the flag is set to N, functionality is disabled.

• If blank, the same behavior as N occurs.

This feature allows for automatic selection of runway(s) based on valid METAR and TAF information for the origin and destination based on ETD and ETA. 

Runways are considered based on the best SID and STAR available and weather criteria (wind speed and direction, approach minima).

NFP also chooses the best runway based on whether the runway is suitable, based on suitability checks (ACN/PCN, runway surface, minimum length), and the magnetic bearing of the runway that yields the greatest headwind component.

Note: Route optimization also has an impact on runway selection.

UI Default Rwy

This parameter works in conjunction with the Default Runways parameter. Options are Y or No. 

• If set to Y, NFP shows the default as set in the Default Runways field. 

• If set to N, you are forced to select a specific runway for both departure and arrival stations. 

• If blank, the same behavior as Y occurs.

Min Rwy Length

Enter the minimum runway length in feet. 

Note: NFP generates a warning if you select a station with a runway length lesser than the value entered in this field.

Closed Rwy Warn

Warn if ANY runway at the airport is closed for Origin, Destination, or Both.

Max Rwy Tail Wind

Enter the maximum tailwind value for your fleet. Entry in this field is in knots per hour (wind speed). 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.

Max Rwy Crs Wind

Entry in this field is in knots per hour (wind speed). Enter the maximum crosswind value for your fleet. 

Incl Wind Gusts

Options are Y or N. 

• If set to Y, wind gusts will be included in crosswind check. 

• If set to N, wind gusts will not be included in crosswind check. 

• If left blank, it will act in the same way as N (no).
