Situational awareness is critical for flight safety. Knowing what conditions you are heading into is vitally important. Collins Aerospace is a leader in the avionics industry with advanced surveillance technology for weather detection and obstacle avoidance.

MultiScan weather radar is a trusted choice in advanced weather avoidance technology, so you’re always aware of potential weather threats. Our systems provide the situational awareness you need to safely and efficiently operate in this ever-changing environment.

MultiScan™ weather radar

Accurately depicting the weather is critical to safety and comfort. Our advanced weather radar solutions enhance your situational awareness with advanced weather avoidance technology, so you’re always aware of potential weather threats. With detection ranges of up to 320 nm and available Doppler™ turbulence detection at ranges of up to 50 nm, our MultiScan family of weather radars give you real-time information on the smoothest, most efficient routes around dangerous weather systems.

RTA-4100 Hazard Detection System

The Collins Aerospace RTA-4100 MultiScan™ Weather Radar delivers comprehensive weather analysis and threat detection. The system provides a true 320-nautical-mile "clutter-free" weather display and enhanced effectiveness as a threat detector. Capabilities such as MultiScan automatic operation, Geographic Weather Correlation, OverFlight™ protection and turbulence detection accurately depict weather and weather-related hazard events – at any location around the globe. The result: a more accurate depiction of weather and turbulence hazards that significantly reduces flight deck workload and training for pilots. The RTA-4100 MultiScan radar supports integration of new sources of data as they become available.
