PRIMUS ® 440, 660 & 880 WEATHER RADARS

Product catalog summary

Overview
The Primus 440, 660, and 880 weather radars by Honeywell are designed for commercial aviation, offering advanced weather detection and turbulence avoidance capabilities. These systems are known for their high performance, reliability, and ease of installation.

Performance and Reliability
All three models feature a transmitter power of 10 kilowatts, narrow pulse width for better signal resolution, and high receiver sensitivity to detect weak signals from distant storms. They are built to withstand harsh environments, such as the aircraft nose, and can operate effectively even in direct showers.

Installation and Integration
The radars are RTA-style, requiring only a display and control panel for installation. They integrate seamlessly with EFIS and various standalone radar and multifunction displays.

Weather Detection and Display
Rainfall intensity is displayed in four colors: magenta for severe, red for heavy, yellow for medium, and green for light rain. The system provides information on operating mode, distance to range marks, and antenna tilt angle.

Advanced Features

REACT: This feature compensates for signal attenuation due to rainfall and alerts pilots to hidden storms.
BITE: Built-In Test Equipment continuously monitors system performance and reports faults.
Lightning Sensor System: Optional LSZ-860 system overlays lightning data on the radar display for enhanced safety.

Additional Features of Primus 660 and 880

Target Alert: Notifies pilots of hazardous targets directly ahead.
Dual Mode: Allows operation as two separate radars with different controller settings.
Sector Scan: Increases scan rate for faster updates during storm activity.

Exclusive Features of Primus 880

Ground Mapping: Provides terrain feature depiction for navigation.
Turbulence Detection: Uses Doppler techniques to identify turbulence within storm cells.
Altitude Compensated Tilt (ACT): Automatically adjusts antenna tilt based on altitude changes.

Feature Comparison
The Primus 880 offers additional features such as turbulence detection, ACT, and ground mapping, which are not available in the 440 and 660 models. All models share core features like high transmitter power, advanced BITE, and REACT.

Support and Maintenance
Honeywell provides extensive support services, including training and a global dealer network, ensuring high reliability and simplified maintenance for the Primus radar systems.

Dual Mode Honeywell’s exclusive Rain Echo Attenuation Dual Mode With two controllers, Primus 660 Compensation Technique (REACT) safety and 880 can be operated like two separate feature alerts pilots to areas where storms may radars. The pilot’s controller settings are used be hidden behind other storms. REACT performs for one sweep, then the co-pilot’s are used for three distinct functions. First, it maintains target calibration by compensating for attenuation caused by intervening rainfall. Second, REACT advises pilots of areas where target calibration cannot be maintained by changing the screen...
