Flight Planning software for theSeries 3a & 3c

Navplan is a flight planning program for the Psion Series 3a and Series 3c palmtop computers. It provides all the functions required for flight planning and preparation - navigation, fuel planning, weight and balance and performance - but runs on a true multi-tasking computer which fits into your pocket allowing you to carry out flight planning anywhere. The program is configurable to match the specific needs of any pilot either private or commercial, flying aeroplanes or helicopters.

Optional modules are available for commercial operators, providing accurate performance information for both aeroplanes and helicopters based on Flight Manual data and graphs. These modules can be approved by the relevant bodies for inclusion in a company operations manual. For more information about performance modules for commercial operations, please contact us.
