STRIKEFINDER Digital Lightning Detection

The STRIKE FINDER® Digital Weather Avoidance System detects and analyzes the electrical activity emanating from thunderstorms within a 200 nautical mile (nm) radius of the aircraft. A unique graphic display plots an accurate, reliable and easily-interpreted picture of electrical activity, that you can use to circumnavigate the hazards associated with thunderstorms. The STRIKE FINDER® System analyzes the individual strike signal properties to determine the bearing, range and severity of the activity. Strike data is plotted on the display as single orange dots by range and azimuth, in relation to the aircraft symbol ("heads up"). As the number of lightning strikes increase, so does the number of plotted strike dots. Cells start to form indicating increased lightning activity.

Bearing and Range

Storm distance and bearing can be determined by using the Outer Range Ring and the Half Range Ring, in conjunction with the 30-degree Azimuth (1:00 and 11:00) markers.

The Outer Range Ring is the outer boundary distance from your aircraft that strike dots are plotted in the selected range. The Half Range Ring is exactly half that distance from your aircraft. (Ex: 200 nm range selection gives a Half Range Ring distance of 100 nm).

Strike Finder System Components

The STRIKE FINDER® has two components: These two components are connected with a shielded cable.

Display - The Display mounts in the aircraft instrument panel. The STRIKE FINDER® can be slaved directly to an HSI or compass system with a standard stepper or synchro-output. The display is available with either a plasma display or our New Ultra Bright LED Display with a single microprocessor-based circuit board that employs Digital Signal Processing, to ensure that the truest possible storm image is displayed. The microprocessor constantly monitors the performance of the entire system, from the Sensor to the Display for proper function.

Sensor - The maintenance-free Sensor is weather-sealed and mounts on the outside of the aircraft fuselage. STRIKE FINDER®, unlike any other system, uses Broad-band Digital Sampling. A greater bandwidth delivers vastly more information for improved signal fidelity and inherently superior noise rejection. This translates into a clearer definition of weather activity, without false or misleading indications.
