Radar intelligence that reaches a new turning point

During turns, MultiScan Hazard Detection uses SmartScan™ technology to ensure that weather in the direction of the turn is displayed promptly and accurately. When an aircraft turns, the scan rate of current-generation automatic radars results in the loss of real time weather information in the direction of the turn, while new weather information is stored in the memory, processed and displayed. The resulting situation is one in which flight crews could be momentarily blind to weather in the direction of the turn.

MultiScan solves this problem by using SmartScan to prioritize the radar scan in the direction of the turn, thus ensuring quick revisit times to detect and display the new weather. As a result, MultiScan gives pilots the complete weather situation throughout the entire 180° sweep of the radar. While new weather in the turn is detected and displayed, the weather information away from the direction of turn remains to provide a complete weather picture.

In this video, you can watch side-by-side how quickly the weather radar updates as the aircraft makes its turn.

The aircraft in this picture is turning right. SmartScan™ ensures rapid update rates by causing the radar to scan just in the direction of the turn. Weather falling off the display is then "pasted" in from digital memory.
