Ilec SN10B Sailplane Computer The SN10B is the easiest to use sailplane computer available. This simplicity means more time looking out of the cockpit, for faster and safer soaring. The SN10B represents the state of the art in variometer and computer functions for sailplanes. It contains extremely accurate sensors for variometer, airspeed, altimeter, and G load, plus an optional GPS satellite navigation receiver. These provide complete variometer functions and show your choice of variometer indications on the external meters plus audio. The SN10B provides a wide range of flight planning and analysis functions. A built-in turnpoint library eases task planning. Continuous estimation of time and altitude required to complete the task provides superb task progress tracking with little effort from the pilot. For turn-area tasks, the pilot can ask the SN10B what-if questions to determine the best task for the time remaining. A simple glideslope presentation, coupled with an accurate digital altimeter, allows final glide monitoring without arithmetic. Final glides around turnpoints are automatically calculated with no pilot effort required. The SN10B’s unique thermal heightband graph allows easy monitoring of lift conditions through the day and eases time-to-leave-this-thermal decisions. Automated estimation of wind strength and direction allows better end-of-task planning and final glides around turnpoints without extra effort by the pilot.
