TWX670 Tactical Weather Detection System

TWX670 Tactical Weather Detection System

The Avidyne TWX670 Tactical Weather Detection System - Lightning is the first physical property of a storm cell that can be detected, and unlike precipitation, lightning is the best determinant of dangerous thunderstorm activity.

Avidyne's new TWX670 from Pacific Coast Avionics is a second-generation lightning-based weather detection system. The TWX670 provides a easily to use and intuitive color-contoured display with instantaneous picture of surrounding weather.

Incredible Accuracy Means Truly Tactical Weather Detection
The Avidyne TWX670 is the first and only lightning-based, real time, tactical, color weather avoidance solution for your aircraft. The TWX670 detects and displays electrical discharges – the primary indicator of thunderstorms – in real time, regardless of aircraft position. With its significantly-improved accuracy over previous-generation lightning detection systems, the Avidyne TWX670 Tactical weather system provides true weather avoidance in the critical 0-25nm range. This is the perfect complement to the strategic benefits of satellite-based datalink weather.

Completing the Picture
Storm cells and their intensities are displayed in color contours (when used with the Avidyne EX500 / 5000 MFD). This eliminates the guessing associated with interpreting legacy weather displays. Providing a color-contoured map of a thunderstorm's electrical activity over time, the Avidyne TWX670 easily allows the pilot to determine the areas of greatest intensity, and clearly identify areas of convective wind shear, turbulence, microbursts, hail and icing.
