Avidyne’s TWX670 is a third-generation lightning-based weather detection system that provides a simple and intuitive color-contoured display with instantaneous picture of surrounding weather.

Great Accuracy Means Truly Tactical Weather Detection

The TWX670 is the first and only lightning-based, real time, tactical, color weather avoidance solution. It accurately detects and clearly displays electrical discharges– the primary indicator of thunderstorms–in real time, regardless of aircraft maneuvering. With its significantly-improved accuracy over previous-generation lightning detection systems, the TWX670 provides true tactical weather avoidance in the critical 0 – 25nm range, making it a perfect complement to the strategic benefits of satellite-based datalink weather.

TWxCell Mode™

With the TWX670’s color-contoured TWxCell Mode, pilots can identify the most intense regions of storm activity. Color-filled hexagons present a visually contoured color display with dynamic sectors.

The TWX670 combines the data of all lightning activity occurring over a running three-minute period, regardless of the number of strikes. This provides a meaningful dynamic map of the lightning discharge rate and density for immediate visual acquisition of critical information. With the TWX670, there’s no need to spend time observing discrete events to determine the level of thunderstorm activity.

Strike Mode

In Strike Mode, up to 1024 strikes are displayed for up to 3 minutes. Each transmitted strike includes range, bearing, and weight (color). Regional activity, not age, determines the strike color. Strikes that are more recent but further away cannot “drown out” flashes that are closer and less recent. This provides a level of comfort to pilots transitioning from less capable systems. Color enhancement helps to identify areas of high intensity while still providing a view of the discrete events.
