Cumulus is a well established Open Source flight navigation software written for glider pilots and other flight enthusiasts. It uses the Qt 4.x framework. Packages are provided for:

Linux desktop running Ubuntu
Nokia Internet Tablets N8x0 and N900
Android devices running release FroYo and higher at Google play
Link to the source archive at GitHub:

Cumulus provides a moving map display with all the information you need to make navigation easier while flying, yet requiring a minimum of user interaction. Navigation during flight is based on the processing of GPS information delivered either by a built in GPS receiver or an external GPS device connected via RS232, USB or Bluetooth.

Cumulus features a full color moving map with information on terrain, airfields, airspace, (rail-) roads, water, cities and many other details. It handles waypoints, IGC logging and tasks in cooperation with KFLog. Wind determination, reachable sites, final glide, sunrise and sunset calculations, as well as automatic task point switching are also supported.
