AspEdit manual Airways
Airways use a different method for their definition as the other
Other areas are constructed out of geographical points + circles and
border segments. Airways are constructed by defining a
width (total width: left + right), and fixes. Fixes can be
waypoints or navigation aids. This means that those have to be
defined first, see Navaids / waypoints.
Defining an airway
- Switch the list to airspace
- Press the add button to create a new area, or double-click on
an existing area, in order to edit it. The area dialog box will open.
- In the type field, select "AWY". fill in the other
fields as desired.
- From now on, adding / inserting / editing lines in the shapes
will define airway segments via fixes.
- At each fix, the airway width can be specified.
The first fix has to include a width value, otherwise a error
message will be issued.
Verify the results of the editing on the map display. The map
display can be panned / zoomed while the area dialog box is
- If the width field remains blank, the same width is used as
the previous segment.
- If a width is given, the width is applied from that fix
onward, until a new width is specified.
Adding / subtracting areas from an airway
The border segment does not work for airways. Instead, use the
Adding / subtracting shapes function.
Example: In the demo file, there is an airway "Test AWY".
Suppose you want to exclude the area over Germany. Proceed as
Several areas can be added (subtracted) to the same airway.
- Open the area dialog box for the
- At the end of the airway (always after the last fix, even if
the intersection will be several fixes before), use the Add
- The airway dialog box will
- Near the bottom of the dialog, press "Add shape", the Add shape dialog box will open.
- Read the help topics Adding

The OpenAir export dialog box allows
The resolution of the circle segments is
as defined in the Map settings
- Normal: the airway will be defined by width and "DY" records,
- Expanded: the airway will be defined by geographical points
defining the edges, as displayed on the AspEdit map.
Note: if the the adding / subtracting shapes function was
used in an airway, that airway will always be exported as expanded
