Cumulus is a flight navigation program aimed at the soaring community. The first generation of Cumulus runs on Zaurus and iPaq hardware with a Linux OS under Qtopia respectively Opie by using Qt class library Release 2.x. With the disappearance of the old hardware platforms new alternatives must be searched. The new hardware platform is the Nokia Internet Tablet N800/N810 with Maemo OS2008 by using Qt class library Release 4.x
Cumulus provides a moving map display and all the information you need to easily navigate while requiring a minimum of user-interaction. It uses a NMEA compatible Bluetooth GPS receiver to provide it with information on the current position, altitude, heading and speed. Of course Cumulus supports flight tasks, waypoints and can calculate the distance and heading to your waypoint, arrival altitude, wind force and direction, sunrise and sunset times, etc.
Take a look at our Screenshots page for a quick impression of what Cumulus can do. The Cumulus packages come without any maps pre-installed, but you can get all the maps you need from our Maproom. There, you'll find information on the different kinds of maps that are available for use with Cumulus. We have maps for the entire world!

Cumulus is a fork of the KFLog project, a program aimed at flight planning and flight analysis for gliders. Cumulus is mend to function as a companion for KFLog.
Cumulus and KFLog functionality does not overlap but is closely related. In fact, the two projects are complementary to each other: First, KFLog can be used to plan out a task to fly. Then you use Cumulus during your flight to help you to accomplish said task using it's navigational and flight calculations features. Finally you take the logfiles you made with Cumulus from your PDA within KFLog and analyze your days' flight.
