Runway & Approach Tab




Default on UI: 

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

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

  • If set to No, you are forced to select a specific runway for both departure and arrival stations. 

  • If blank, the same behavior as Yes occurs.

Defaulting Method 

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.

This parameter must be set to M or B to enable the automatic runway selection based on valid TAFs. 

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

  • If blank, the same behavior as occurs.

Note: 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.

Weather criteria

Terminal Area Forecasts and METARs are monitored for the flight’s ETD and ETA. The forecasted winds for the appropriate time period are used as criteria for the preferred runway selection. METARs are only applicable when the expected departure or arrival is to happen within an hour, after which, only the TAFs are used

Note: NFP does not account for sudden runway changes which may be made by ATC facilities. ETA prior to initial compute = ETD + EET based on GC distance (between origin and destination) using default settings in aircraft type file @ 75% MTOW.



Integration Weather 

Options are Yes or No

  • If set to Yes, 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. 

  • If field left blank and send a runway request to Aerodata, Aerodata will populate the fields with their data.

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

Integration Pressure

Choose which runway integration pressure unit to display. Options are Millibar or Inches of Mercury

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

Minimum Length

Field entry is in feet. NFP generates a warning if you select a station with a runway length lesser than the value entered in this field.

Description automatically generated with low confidence

Warn if Closed

Options are Origin, Destination or Both

  • If set to Origin, or Destination a warning is displayed if any runway is closed at the Origin or Destination airport. 

  • If set to Both, a warning is displayed if any runway is closed at either of the airports.

Maximum Tailwind

Entry in this field is in KNOTS (wind speed nautical miles per hour). 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. 

Note: When set, NFP does not pick a runway for departure or arrival if the tail wind exceeds this value.

Maximum Crosswind

Entry in this field is in KNOTS (wind speed nautical miles per hour). Enter the maximum crosswind value for your fleet. This value impacts automatic runway end selection for NFP features, such as Max crosswind and ALC Approach Minima. 

Note: When set, NFP does not pick a runway for departure or arrival if the crosswind exceeds this value.

Include Wind Gusts

Select this checkbox to include Wind Gusts in the Tail/Cross check as well as the default Maximum Crosswind setting.




Landing Approach

This drop down list enables the ALC Approach Minima feature

  • If set to Yes, NFP considers runway specific approaches for all STARs and DCT segments to the airport which will use a landing approach. NFP selects the optimized one based on weather criteria and approach preferences as set in the second field. 

  • If set to No, behavior is the same as N (no landing approaches).

Note: There is also a Suitability Only option which checks to discern if there is a suitable approach available, but does not add it to the flight route.

Approach Types

Enter the preferred approaches in order of most preferred to the least preferred. Available options are:

If NFP cannot pick the first preferred approach because of approach minima or suitability checks, it will move on to the second choice and so on.

The Landing Approach field allows commas between approach types. This allows users to group approach types for ranking purposes.


IJPR,DSVLBQ,NGXU   I/J/P/R are preferred, and ranked equally.  

D/S/V/L/B/Q are only considered if no I/J/P/R were available for use.  This group is also equally ranked among each other.  

N/G/X/U are only considered if none of the above were available for use.  This group is also equally ranked among each other.
