### Waypoints

Waypoints are used in Cumulus to support the navigation. When used in tasks they also serve as turnpoints. Waypoints can be created or edited inside cumulus or by using KFLog on the Linux desktop, where you can more easily maintain the waypoint list.

Waypoint file remarks
  At the moment Cumulus supports only one waypoint file. This file is installed under your selected Data Directory. As waypoint file name must be used cumulus.kwp. This is a hardcoded name.
Waypoint file transfer
  You can transfer the waypoint file between your desktop PC and your PDA but notice, that Cumulus is not running during the file transfer. That can cause a corrupted file.
Waypoint list display
  To open the waypoint list tipp at the waypoint display, located at the left upper corner on the map screen. Now you can see all your known waypoints sorted in alphabetically order. With different buttons in the window you can modify the waypoint list or do other things.

  - Press one of the filter buttons above the list to navigate to a certain waypoint.
  - Press the plus button to create a new waypoint.
  - Press the pencil button to edit the selected waypoint.
  - Press the trash button to remove the selected waypoint.
  - Press the house button to set the selected waypoint as your new home position.
  - Press the Info button to get displayed the details of the selected waypoint. The info screen for a waypoint will close automatically after some seconds. Press the Keep button to prevent this. The New Home button sets this waypoint as your new home position.
  - Press the Select button to make the selected waypoint to your new target. The hardware keys Return or Select do the same. You may want to use V after selecting a waypoint to ensure it is visible on the map.
Waypoint list filters
  You can narrow down the list of waypoints using the buttons above the list. These act as a filter. In only a few steps, you can reduce a list of thousands of items to only a few, making it much easier to find the waypoint you are looking for.
Creating a waypoint from the current position
  At any time you can press R or tipp on the baering icon on the map to remember the current position. A waypoint with the name WPx-HH:MM will be generated that contains the current coordinates and altitude, where HH:MM is derived from the current UTC time. The new waypoint is shown in the map display and can be edited in the waypoint screen as any other waypoint.
Waypoint management
  If you want to add, modify or delete waypoints use the icons above the waypoint list. For security reason it is not recommended to do that in flight! If you press new or edit an editor is is opened with entry fields for the waypoint properties.
Waypoint importance
  The importance property deserves some explanation. To prevent overcrowding the map with waypoints if you zoom out far, not all waypoints are drawn at all zoom factors. You can control which waypoints is to draw by selecting the importance. If you select high the waypoint will always be drawn. This would be appropriate for your home site and other important sites. If you select normal the waypoint will be drawn in normal zoom modes but not if you zoom out too much and the low importance waypoints are only drawn if you zoom in far enough. The currently selected waypoint is always visible. In the configuration setup of Map Objects you can the define the scale borders for every importance property. See here for more information.
Waypoint runway directions
  In the wayoint editor you have two combo boxes for runway directions. The handling of runway directions is a little bit tricky and derived from the Welt2000 handling. The following possibilities do exist:

  - 09/27 means there is one runway with two useable directions. Note! The difference between the two directions must be always 18.
  - 09/09 means there is one runway with only one useable direction.
  - 09/18 means there are two runways 09/27 and 18/36 with two useable directions. Note! The difference between the two directions must not be equal 18.
Waypoint names and extra information
  Via the menu bar entries View->Waypoint lables and extra info you can switch on the display of the waypoint names and their reachability (distance and arrival altitude) besides their icons, if a glider is selected. The text labels are drawn at a white background with black letters. The currently selected waypoint is drawn revers. If a waypoint is land- and reachable the text is drawn bold. The extra information distance and arrival altitude are only displayed, if the landable attribute of the waypoint is set. If the waypoint is below your safety altitude, the text box frame is drawn in red color.
Final glide calculations
  Waypoints are also used for final glide calculations. If you plan to use this feature of cumulus, please make sure that you correctly enter the position and the elevation of the waypoints! Otherwise you will get unpredictable results.
