Flight Plan Editor
The GCS can be launched with the -edit option which adds an Edit menu. A simple layout is displayed with only two parts, the map and the XML view. See here for some flight plan examples.
The Edit menu offers to load a flight plan or to create new one from scratch. In the latter case a simple template flight plan is loaded after filling in some entries in the toolbox (geographic reference, name, etc).
Only one flight plan is editable at a time. It must be saved in the conf/flight_plans directory.
Note that the map displays only the waypoints and the safety area. Trajectories (circles, segments, ...) do not appear and are editable only through the XML description.
The XML window is a syntactic editor which follows the grammar of a flight plan (from the DTD description). It is divided into two columns for elements and attributes. The elements are displayed as a tree while the attributes are displayed a list of pairs name-value.
Navigation in the tree is done in the standard way. Elements can be dragged across the tree, with the constraints of the grammar (a waypoint element cannot be dragged in a block). Elements are added with a right-click which pops up a contextual menu related to the pointed element. Deletion is done with this popup menu or with the DEL key.
The attributes of the selected element are displayed in the right column. Each value is editable. Right-click also gives a popup menu containing the allowed attributes for the current element.
Waypoints can be created from the XML editor or directly in the 2D map with CTRL-Left-Click. The waypoints are movable (click and drag) and editable (single click).
Complex flight plans should always be carefully tested prior to flight. See the simulation page for details.
