Stay aware of all potential weather at all times

MultiScan's OverFlight™ protection technology is designed to prevent unintentional flights over lower-level storms, commonly known as clear-air turbulence. It is estimated that as much as 65 percent of clear air turbulence is, in fact, turbulence associated with unintended over flight of a lower-level storm. Why? At cruise altitudes, with tilt and gain adjusted to display en route weather, it is not uncommon for current generation radars to scan over the reflective portion of a storm, while the low-reflective top portion of the storm that is still in the aircraft flight path goes undetected.

The clouds in this photo are examples of oceanic storm clouds that could cause clear-air turbulence and would normally disappear from the radar display at 40 nautical miles from the aircraft.

MultiScan uses a combination of lower- and upper-beam information, combined with stored data, to continue to display the low-reflectivity thunderstorm tops that would normally disappear from the screen as range decreases inside approximately 40 nautical miles. These storm tops will remain on the display until they pass behind the aircraft. By continuing to display these storm tops, MultiScan ensures that the pilot is aware of all significant weather and possible associated potential turbulence that could ultimately affect the passengers and crew.

This video demonstrates how OverFlight Protection eliminates the possibility of flying into a developing cell at night or while in the clouds.
