  • Page 17: Weather Detection

    IntuVue RDR-4000 Weather Radar Pilot's Guide WEATHER DETECTION AUTOMATIC WEATHER MODE (AUTO) GENERAL DESCRIPTION AUTO mode provides weather, turbulence, and predictive windshear detection. The system processes the data to fill the 3D memory and extracts the selected data for display. When a PWS event is detected, an icon is shown on the display.

The radar does not directly detect hail or lightning;...

  • Page 21: 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).

  • Page 22: Predictive Windshear (Pws) Detection

    IntuVue RDR-4000 Weather Radar Pilot's Guide PREDICTIVE WINDSHEAR (PWS) DETECTION The Predictive Windshear feature detects the presence of windshear 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. Configuration A: • Between 50 ft and 1,500 ft AGL the system indicates ADVISORY Alerts by overlaying the Windshear icon on the radar display.

  • Page 43: 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 44: 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 can be correlated to precipitation rate, and is displayed as green (light), yellow (moderate), and red (heavy) precipitation.
  • Page 45 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 of updraft and downdraft features, stratiform precipitation results from much more widespread and much less vigorous uplift.

  • Page 46: 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 47 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...
  • Page 48 IntuVue RDR-4000 Weather Radar Pilot's Guide Generally, consider cells with any magenta turbulence and hail icons as the most hazardous cells, then in order of decreasing severity: Cells with turbulence and lightning indications (no hail  indications) Cells with no hazard icon, but with turbulence indicated.

  • Page 49: 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 50: 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. If the Hazard Display features are installed, a REACT field will indicate attenuated areas (see page 17).

  • Page 51: 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 52 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 54: Radar Windshear Detection

    IntuVue RDR-4000 Weather Radar Pilot's Guide RADAR WINDSHEAR DETECTION During both takeoff and landing, microbursts have been the result 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 55: 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.

    IntuVue RDR-4000 Weather Radar Pilot's Guide SECTION 6: RDR-4000 TECHNICAL OPERATION 3D VOLUMETRIC MEMORY SCANNING/PROCESSING The RDR-4000 collects a complete 3D volumetric scan of all the weather and terrain ahead of the aircraft. The RDR-4000 contains an internal worldwide topography database, enabling it to extract ground clutter without the significant losses associated with signal-based ground clutter suppression techniques.

  • Page 58: Ground Clutter Extraction

    IntuVue RDR-4000 Weather Radar Pilot's Guide GROUND CLUTTER EXTRACTION The radar processor contains an internal topography database with elevation data. The radar compares the collected reflectivity data with the topography database. Reflectivity data that correlates to terrain data is considered ground-clutter, and is suppressed from the weather images.

  • Page 60: Envelope Boundary Definition

    IntuVue RDR-4000 Weather Radar Pilot's Guide An envelope is applied around the intended flight path: weather within the envelope is considered Flight Path Weather; weather outside the envelope is Secondary Weather. On the display, Secondary Weather is distinguished from Flight Path Weather by black stripes. The flight path angle is based on the ratio of calculated vertical speed to ground speed.

  • Page 61: Manual Weather Analysis Mode (Man): Constant Altitude

    IntuVue RDR-4000 Weather Radar Pilot's Guide MANUAL WEATHER ANALYSIS MODE (MAN): CONSTANT ALTITUDE Constant altitude mode is an analysis mode that provides a constant altitude slice throughout the entire 180-degree plan view. It is called constant altitude because the altitude slice extracted from the memory is corrected for the earth’s curvature.
  • Page 62 IntuVue RDR-4000 Weather Radar Pilot's Guide The example below demonstrates the constant altitude mode. In the top center picture the system is in the AUTO mode at an aircraft altitude of 20,000 ft MSL. In the second center picture, MAN mode has been selected, so this is an altitude slice at the current aircraft altitude (20,000 ft MSL).
