PRIMUS® 440, 660 & 880 WEATHER RADARS Reliable Weather Avoidance Radar Commercial Aviation’s Most Powerful Integrated RTA Weather Radar with Turbulence Detection. Operators want quality radar performance, improved reliability and advanced features – they also want a light integrated receiver/transmitter/antenna (RTA)architecture that’s easy to install. Honeywell’s Primus® 440/660/880 family of radars meet these requirements and are by far the most powerful, feature-packed weather radars on the market. The Primus 440, 660 and 880 all offer: Performance and Reliability Installation The Primus 440, 660 and 880 are designed radar, installation is straight-forward. The system using all of Honeywell’s weather radar expertise requires only a display and a control panel to to provide the ultimate in both performance and complete the package. reliability. The Primus 440, 660 and 880 excel in all three weather radar performance categories. Transmitter power: 10 kilowatts of power allows for unsurpassed range in class. Since the Primus 440, 660 & 880 are RTA- style Weather Detection Rainfall intensity levels are displayed in four brilliant colors contrasted against a black background. The result is a crisp display that Pulse width: Primus 440, 660 and 880’s makes any target readable under any cockpit narrow pulse width provides better resolution lighting conditions. Magenta represents areas of the reflected signal which makes it easier to of severe rainfall, red shows heavy rainfall, yellow distinguish ground from weather. represents medium rainfall and green indicates light rain. To help in analyzing the storm, Honeywell, the world’s leader in avionics continues to set the standard in weather radar systems with the Primus® 440, 660 and 880 family of radars. Receiver sensitivity: Primus 440, 660 and 880’s Honeywell’s Primus 440, 660 and 880 informs high receiver sensitivity allows the radar to detect pilots of the operating mode, distance to each extremely weak signals from distant storms. range mark and antenna tilt angle. Primus 440, 660 & 880 vs. Its Hostile Environment Displays A radar system is installed in one of the most with EFIS as well as a number of stand-alone hostile environments on an aircraft–the nose. radar displays and multifunction displays. Water in the radome can cause weather radar problems. Primus 440, 660 & 880 has been designed to work in the worst of all environments, even a direct shower. Primus 440, 660 and 880 naturally integrate REACT 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 the subsequent sweep. 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 background to blue, warning that attenuation may be hiding areas of severe weather. Third, REACT Sector Scan In normal mode, Primus 660 and 880 scans once every four seconds. In Sector Scan (SECT) mode, the scan rate increases to two seconds when faster updates are needed due to storm any target displayed in the blue field will appear activity directly ahead on short range. in magenta to alert the pilot to its probable BITE THE PRIMUS 880 ADDITIONAL FEATURES INCLUDE: Ground Mapping Built-In Test Equipment (BITE) features Ground mapping (GMAP) is a navigation aid, complete RF loop-back which continuously and the Primus 880 has a mode specifically for tests the transmitter power and receiver depicting terrain features. severity. sensitivity and reports any faults to the pilot. BITE also monitors the time of operation in every mode, the time at incremental altitudes and the time at incremental temperature to help service technicians identify any faults. Turbulence exposes pilots, passengers and aircraft to unnecessary risk that may be present in any level of precipitation – even those with weak radar returns that may appear safe to fly through. The Primus 880 radar uses advanced Honeywell’s optional LSZ-860 Lightning Sensor Doppler “pulse pair processing” techniques System (LSS) protects aircraft from the inherent to detect spectrum spreading caused by hazards of lightning. The overlay of lightning turbulence within any storm cell — regardless information onto the precipitation/turbulence of rainfall rates. Once detected, the turbulent display of the Primus 440/660/880 provides areas are displayed in white on all ranges up to the safest and most powerful severe weather 50 nautical miles. This allows pilots to safely avoidance tool available today. maneuver around uncomfortable, possibly Target Alert (TGT) notifies the pilot of potentially hazardous targets directly in front of the aircraft that are not yet within the selected range. When “T” is displayed in green, Target Alert is armed. When the yellow “TGT” is displayed (left), the pilot is warned of a red level target directly in front of the aircraft (within ±7.5° of the aircraft’s nose). Sector Scan Turbulence Detection LIGHTNING SENSOR SYSTEM THE PRIMUS 660 AND 880 ADDITIONAL FEATURES INCLUDE: Target Alert Target Alert Ground Mapping Turbulence Detection hazardous weather. Altitude Compensated Tilt (ACT) ACT allows easier detection of weather that may affect the aircraft in an en route condition and reduces the amount of tilt management required by the pilot. When ACT is selected, the Primus 880 reads the altitude and selected range, then points the antenna at the ground just inside the selected range. ACT automatically adjusts the tilt with any change in altitude. ACT also changes the tilt control from the normal ±15° to ±2° for finer control. Primus 440, 660 and 880’s narrow pulse width provides better resolution of the reflected signal which makes it easier to distinguish ground from weather.
