    IntuVue RDR-4000 Weather Radar Pilot's Guide WEATHER DETECTION AUTOMATIC WEATHER MODE (ALL/ALL WX or ON PATH/ PATH WX) GENERAL DESCRIPTION The ALL/ALL WX and ON PATH/ PATH WX modes provide weather, turbulence, and predictive windshear detection. The system processes the data to fill the 3D memory and extracts the selected data for display.
  • Page 17 IntuVue RDR-4000 Weather Radar Pilot's Guide ALL/ ALL WX WEATHER Select the ALL/ALL WX mode to display both on path and off path weather. The off path weather is displayed with black stripes through it. (See diagram on page 34.) This mode is useful for situational awareness and to aid in making changes to your flight plan to avoid on path weather.

    IntuVue RDR-4000 Weather Radar Pilot's Guide TURBULENCE DETECTION Turbulence detection is an automatic function of this weather radar system. For turbulence detection and evaluation use the following procedure: 1. System Control: 1 or 2 (dual system) or 1 (single system) 2.
  • Page 19: Predictive Hail And Lightning (Hazard Display Feature)

    IntuVue RDR-4000 Weather Radar Pilot's Guide PREDICTIVE HAIL AND LIGHTNING (Hazard Display Feature) If the Hazard Display Configuration of the radar system is installed, icons will be displayed on top of the reflectivity to identify areas that have the signature characteristics of hail, lightning, or both.
  • Page 20: React (Hazard Display Feature)

    IntuVue RDR-4000 Weather Radar Pilot's Guide REACT (Hazard Display Feature) REACT stands for Rain Echo Attenuation Compensation Technique. As the transmitted radar signal travels through heavy rain it loses power, or becomes attenuated. If this attenuation is severe enough, weather behind a storm cell may not be detectable, or it may be displayed as being less severe than it actually is (e.g., green instead of yellow).

    IntuVue RDR-4000 Weather Radar Pilot's Guide PREDICTIVE WINDSHEAR (PWS) DETECTION The predictive windshear feature detects the presence of windshear up to 5 nm ahead of the aircraft, giving 10 to 60 seconds of warning before the encounter. Windshear detection mode operates automatically below 1,800 ft Above Ground Level (AGL), with alerts available at 1,500 ft AGL and below.
  • Page 23 IntuVue RDR-4000 Weather Radar Pilot's Guide ADVISORY ALERTS  The Advisory Alert region is ±40° from the aircraft track and from 0.5 nm to 5.0 nm in front of the aircraft.  Between 50 ft and 1,500 ft AGL the system indicates ADVISORY Alerts by overlaying the windshear icon(s) on the radar display.

  • Page 41: Section 5: Principles Of Weather Radar Use

    IntuVue RDR-4000 Weather Radar Pilot's Guide SECTION 5: PRINCIPLES OF WEATHER RADAR USE WEATHER RADAR PRINCIPLES Airborne weather avoidance radar, as its name implies, is for avoiding severe weather - not for penetrating it. Whether to fly into an area of radar echoes depends on echo intensity, spacing between the echoes, and the capabilities of both pilot and aircraft.
  • Page 42: Storm Cell Characteristics

    IntuVue RDR-4000 Weather Radar Pilot's Guide STORM CELL CHARACTERISTICS Airborne weather radar allows pilots to identify and avoid potential weather hazards. The radar performs signal processing to estimate the radar reflectivity of the weather ahead. Reflectivity correlates to precipitation rate, and is displayed as green (light), yellow (moderate), or red (heavy) precipitation.
  • Page 43 IntuVue RDR-4000 Weather Radar Pilot's Guide STRATIFORM WEATHER In addition to reflectivity associated with convective weather, the radar will typically display reflectivity associated with stratus, or stratiform, weather. Whereas convection is characterized by localized towers with updraft and downdraft features, stratiform precipitation results from much more widespread and much less vigorous uplift.
  • Page 44: Planning A Path

    IntuVue RDR-4000 Weather Radar Pilot's Guide PLANNING A PATH Remember to plan a deviation path early. Simply skirting the red or magenta portion of a cell is not enough. Wherever possible, plan an avoidance path for all weather echoes which appear beyond 100 nm since this indicates they are quite dense.
  • Page 45 IntuVue RDR-4000 Weather Radar Pilot's Guide PATH PLANNING CONSIDERATIONS  Where possible, any indicated reflectivity should be avoided.  Reflectivity may generally be penetrated if the crew is sure that the reflectivity is associated with stratus (non-convective) rainfall. Stratus rainfall is characterized by widespread, relatively uniform reflectivity, with tops often below 25,000 ft, and with little or no indication of turbulence.
  • Page 46 IntuVue RDR-4000 Weather Radar Pilot's Guide areas where the REACT field is shown, expect the possibility of additional weather that may need to be avoided. Generally, consider cells with any magenta turbulence and hail icons as the most hazardous cells, then in order of decreasing severity: ...
  • Page 47: Azimuth Resolution

    IntuVue RDR-4000 Weather Radar Pilot's Guide AZIMUTH RESOLUTION Azimuth resolution is a function of the beam width. When two targets are closely adjacent in azimuth and at the same range, the radar may display them as a single target. However, as the targets are approached they appear to separate.
  • Page 48: Shadowed Areas

    IntuVue RDR-4000 Weather Radar Pilot's Guide SHADOWED AREAS Extremely heavy rainfall or high terrain can reduce the ability of the radar to penetrate and present a full picture of the weather area. This is called radar attenuation. Use MAP mode along with the weather modes to identify areas of shadowing.
  • Page 49: Effects Of Interfering Rf Sources

    IntuVue RDR-4000 Weather Radar Pilot's Guide EFFECTS OF INTERFERING RF SOURCES An interfering radio frequency (RF) source operating at a frequency close to the radar’s operating frequency can create unusual returns on the display. The interference may appear as occasional isolated dots, or as radial spikes of any color (including magenta) on the display.
  • Page 50 IntuVue RDR-4000 Weather Radar Pilot's Guide This figure shows a zoomed-in view of the near-range interference from the previous figure. In this figure, the interference is a bit more subtle, as it is mixed in with real weather. However, a close look reveals several radial spokes. The two most obvious ones have been circled.

  • Page 52: Radar Windshear Detection

    IntuVue RDR-4000 Weather Radar Pilot's Guide RADAR WINDSHEAR DETECTION During both takeoff and landing, microbursts have been the cause of numerous transport aircraft accidents. WINDSHEAR/MICROBURST DESCRIPTION A microburst is a cool shaft of air, like a cylinder, between ½ and 1½ nm across that is moving downward.
  • Page 53: Windshear Avoidance Flying

    IntuVue RDR-4000 Weather Radar Pilot's Guide WINDSHEAR AVOIDANCE FLYING The air shaft of a microburst creates problems for aircraft for two reasons. The first problem is due to the downward air movement. Since the aircraft is flying within the air mass, as the air mass plummets earthward, so does the aircraft.

The RDR-4000 contains an internal worldwide terrain database, enabling it to extract ground clutter without the significant losses associated with signal-based ground clutter suppression techniques.
  • Page 56: Ground Clutter Extraction

    IntuVue RDR-4000 Weather Radar Pilot's Guide Views are no longer limited to the single diagonal slice that is inherent to conventional radars. The standard horizontal view of the radar represents a weather envelope based on flight path slope, and corrected for the curvature of the earth. Horizontal views are generated independently for each side of the cockpit.

  • Page 58: Envelope Boundary Definition

    IntuVue RDR-4000 Weather Radar Pilot's Guide The separation is done by applying an envelope around the intended flight path: weather within the envelope is considered on path weather; weather outside the envelope is off path weather. On the display, off path weather is distinguished from on path weather by black stripes (see illustration on page 34).
  • Page 59: Weather Analysis Mode: Constant Elevation

    IntuVue RDR-4000 Weather Radar Pilot's Guide WEATHER ANALYSIS MODE: CONSTANT ELEVATION Constant elevation mode is an analysis mode providing a constant elevation slice throughout the entire 180-degree plan view. It is called constant elevation because the elevation slice extracted from the memory is corrected for the earth’s curvature.
  • Page 60 IntuVue RDR-4000 Weather Radar Pilot's Guide The example below demonstrates the constant elevation mode. In the top center picture the system is in the ALL/ALL WX mode at an aircraft altitude of 20,000 ft MSL. In the second center picture, ELEVN mode has been selected, so this is an elevation slice at the current aircraft altitude (20,000 ft MSL).
