The LSZ-860 lightning sensor system (LSS) detects areas of lightning activity in a 200-nautical mile radius around the aircraft.

The LSS detects both visible and high energy invisible electromagnetic and electrostatic discharges (lightning) that may indicate areas of turbulent activity, allowing the pilot to plan a course to avoid the hazardous weather.

Because some of the heaviest turbulence occurs during the growth stage of a thunderstorm, the LSZ-860 is the ideal complement to a weather radar. The system is designed to detect electrical discharge activity that the radar cannot see. It then maps the lightning activity onto the weather radar display so the pilot can safely navigate the skies.
