37. Departure and Destination Runway

A departure or destination runway can be selected instead of a SID or an approach procedure. This can be used on small airstrips as well.

The inserted departure or arrival legs (runway center line extensions) can be used similar to procedures. Deleting a leg removes the whole departure or arrival, for example.

37.1. Limitations

The departure and arrival runways as well as the related waypoints are exported as custom waypoints (or coordinates) in some flight plan formats like MSFS PLN, X-Plane FMS and others.

Note

The custom waypoints are omitted for all formats related to complex aircraft having an FMS or MCDU to avoid issues on import. You have to select the departure and approach manually in the aircraft, therefore. Depending on add-on you probably have to remove the additional waypoints in the FMC or MCDU before seleting the runway in the aircraft.

If you see problems, delete the departure or/and approach, export the flight plan and undo your change in the flight plan again.

37.2. Show Departure Procedures and Show Arrival Procedures

The buttons Show Departure Procedures or Show Arrival Procedures jump directly to Search Procedures where you can view and select IFR procedures like SID, STAR and approaches.

37.3. Wind Indication

The preferred runway is shown in the departure and destination runway selection dialog window.

This is based on the selection in menu Weather -> Airport Weather Source and shows the best runways for wind and the used weather source.

The head and crosswind is shown for each runway in the selection table.

37.4. Departure Runway

Set this by using Select Departure Runway or Procedure. Set Departure Runway or from the context menu of the airport search tab.

Selecting a departure runway adds an extended runway center line. The length of the runway extension can be changed when adding the departure runway.

The departure guidance is a part of the flight plan similar to a procedure.

The departure runway is saved in the LNMPLN flight plan file. User defined waypoints are used for the runway threshold and end of extended runway center line when exporting a departure runway to other flight plan formats than LNMPLN.

The extended runway center line consists of two waypoints which also indicate the runway name:

  • RW01+3: The start of the final leg. Distance after + given in NM.

  • RW01: The runway threshold for runway 01 here.

Runway selection dialog:

  • Dialog header: Shows the airport name and its ICAO ident as well as field elevation.

  • Runways: List of available runways for the airport. Shows runway name, length, width, magnetic heading, surface, lighting status and other attributes.

  • Length of the extended runway center line: Distance from the runway threshold to the end of the departure leg. Default is 3 NM.

A click on the OK button or a double click into the list Runways closes the dialog and creates the approach.

37.5. Destination Runway

Set this by using Select Destination Runway or Procedures, Set Destination Runway or from the context menu of the airport search tab.

Selecting a destination runway consists of a final leg for the approach which can be customized by changing altitude, length and offset angle. This enables vertical guidance in the elevation profile and allows to the VASI slope at the destination.

The approach guidance is a part of the flight plan similar to a procedure unlike Traffic Patterns which is only a map display feature.

This type of approach can be removed like other procedures by deleting one of the legs in the flight plan table or from the map context menu ( Delete from Flight Plan).

The destination runway is saved in the LNMPLN flight plan file. User defined waypoints are used for the start of the final leg and the runway threshold when exporting a destination runway to other flight plan formats than LNMPLN.

The approach guidance for a selected destination runway consists of two waypoints which also indicate the runway name:

  • RW12+3: The start of the final leg. Distance after + given in NM. The altitude is fixed and considered when calculating the elevation profile.

  • RW12: The runway threshold for runway 12 here.

Runway selection dialog:

  • Dialog header: Shows airport name and its ICAO ident as well as field elevation.

  • Runways: List of available runways for the airport. Shows runway name, length, width, magnetic heading, surface, lighting status and other attributes.

  • Start of final to runway threshold: Distance from the initial fix to the runway. Default is 3 NM.

  • Offset angle relative to the runway heading: Defines an offset angle to approach the runway. This rotates the final leg clockwise for positive values and counter-clockwise for negative angles.

  • Final course to runway: Shows the magnetic course of the final leg based on the offset angle.

  • Altitude above runway at start of final: Altitude at the start of the final leg above runway elevation. Default is 1,000 ft.

  • Approach slope: Shows the slope angle calculated from the given distance and altitude. The default values for distance and altitude give a 3.1 degree slope.
