Cumulus
Cumulus is a program designed for the soaring community. It
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
standard NMEA records delivered by a GPS receiver. Additionally, the
proprietary NMEA sentences of some logger devices can be included in the
processing.
Cumulus features a full colour 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.
