TWR-850/WXR-840 Weather Radar Systems
Unprecedented radar performance is now available with the Collins TWR-850/ WXR-840/WXR-800 Weather Radar Systems. State-of-the-art electronic and computer technologies provide operational convenience and features previously available only to large air transport aircraft. Now, the small size and light weight of the TWR-850/WXR-840/WXR-800 makes these radars the choice for the rest of the turbine-powered fleet. In addition, the solid-state transmitter improves reliability and eliminates one of the most troublesome components of conventional weather radar - the magnetron vacuum tube.

In addition to the expected function of detecting precipitation, the TWR-850 also detects accompanying turbulence by using Doppler frequency shift. This technological advancement is made possible by the availability of transmitters with extremely high frequency stability and powerful digital signal processing capabilities.

Features & Benefits
Advanced Doppler-based turbulence and weather detection for faster, better quality weather analysis
Solid-state transmitter provides higher reliability (no magnetron burnout) and allows optimum pulse width for all ranges and modes
Supersensitive coherent receiver architecture with bandwidth optimized for each transmitter pulse width
Virtually eliminates personnel radiation hazard of conventional radars
Ground clutter suppression mode enhances weather returns by minimizing ground returns using Doppler processing
Dual control capability that gives independently selectable range, mode and tilt for pilot and copilot
Auto tilt reduces pilot workload by automatically readjusting antenna tilt after a range or altitude change
