IntuVueRDR-7000 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. Mode: WX ALL, WX PATH, or WX MAN(optionally GMAP) 2. Turbulence: On (may be included on HZD selection) 3.
IntuVueRDR-7000 Weather Radar Pilot's Guide WEATHER-AHEAD INDICATION Weather/Turbulence Ahead indication lets the pilot know when significant weather or turbulence is detected ahead of the aircraft or along the flight plan when the weather display is not active. This is similar to the “Target Alert” function on other radars, except that if this feature is installed, it is always available whenever the radar is scanning.
IntuVueRDR-7000 Weather Radar Pilot's Guide PREDICTIVE WINDSHEAR (PWS) DETECTION The predictive windshear feature detects the presence of windshearup to 5nmahead of the aircraft, giving 10 to 60 seconds of warning before the encounter. Windshear detection mode operates automatically below 1,800 feetabove ground level (AGL), with alerts available at 1,500 feet AGL and below.

IntuVueRDR-7000 Weather Radar Pilot's Guide FAULT ANNUNCIATIONS Fault annunciations alert the pilot that the radar system is not performing to established standards. Built-in test equipment (BITE) automatically and constantly tests the radar system. Failures will generally be indicated by the native mode annunciation on the display changing to amber.Some faults will result inalldisplayed radar data to go away entirely, or the radar may change to Standby mode.
IntuVueRDR-7000 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.
IntuVueRDR-7000 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 49
IntuVueRDR-7000 Weather Radar Pilot's Guide results from much more widespread and much less vigorous uplift. As a result, stratus precipitation is more layered in form with much lower gradients in radar reflectivity. However, the reflectivity of stratiform weather can be sufficient to cause yellow and red on the radar display.
IntuVueRDR-7000 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 display beyond 100 nm since this indicates they are quite dense.
Page 51
IntuVueRDR-7000 Weather Radar Pilot's Guide Hail and lightning icons identify which cells are likely producers of the associated hazard, but do not explicitly detect the present location of the hail or the lightning. Since lightning and hail can extend a significant distance from the core of the cell, the entire cell should be considered as containing the hazard.
Page 52
IntuVueRDR-7000 Weather Radar Pilot's Guide If a squall line or system of cells must be penetrated, plan a path through the weather in a region of the least indicated hazard with the lowest reflectivity, generally staying upwind of the most severe hazards.
IntuVueRDR-7000 Weather Radar Pilot's Guide strong returns from urban areas and mountainous regions, and others. Before making operational decisions based on small isolated indications on the weather display, the validity of these indications should be verified via PIREPS, ground-based weather sources and/or ATC communications.
IntuVueRDR-7000 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 GMAP mode along with the weather modes to identify areas of shadowing.
IntuVueRDR-7000 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 display as occasional isolated dots, or as radial spikes of any color (including magenta) on the display.
Page 56
IntuVueRDR-7000 Weather Radar Pilot's Guide In this figure, the interference is a bit more subtle, as it is mixed in with real weather. However, a close look reveals several radialspokes. The two most obvious ones have been circled. These figures show more examples of RF interference. Principles of Weather Radar Use D201911000094 Rev 0, Feb 2020...
IntuVueRDR-7000 Weather Radar Pilot's Guide RADAR WINDSHEAR DETECTION During both takeoff and landing, microbursts have been the cause of numerous 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. When it encounters the ground, the air mass mushrooms in a horizontal direction curling inward at the edges.
IntuVueRDR-7000 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.
IntuVueRDR-7000 Weather Radar Pilot's Guide SECTION 6: RDR-7000TECHNICAL OPERATION 3D VOLUMETRIC MEMORY SCANNING/PROCESSING The RDR-7000 collects a complete 3D volumetric scan of all the weather and terrain ahead of the aircraft. The RDR-7000 contains internal worldwide topographical information, enabling it to extract ground clutter without the significant losses associated with signal- based ground clutter suppression techniques.
IntuVueRDR-7000 Weather Radar Pilot's Guide GROUND CLUTTER EXTRACTION The radar processor contains an internal terrain database with elevation data. The radar compares the collected reflectivity data with the terrain database. Reflectivity data that correlates to terrain data is considered ground- clutter, and is suppressed from the weather images.
IntuVueRDR-7000 Weather Radar Pilot's Guide ON PATH WEATHER VS. OFF PATH WEATHER The WXALLorWX PATH modesare used for the strategic detection of weather. This fully automatic weather detection is enabled by the 3D volumetric memory. In these modes, OnPath weather, or weather near the altitude of the intended flight path, is displayed as distinct from Off Pathweather, which is further removed in altitude from the flight path.
IntuVueRDR-7000 Weather Radar Pilot's Guide WEATHER ANALYSIS MODE: MANUAL ALTITUDE Manual Altitude 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. With traditional tilt angle settings the earth curves away from the beam farfrom the aircraft making it difficult to exactly measure the height of a cell.
Page 64
IntuVueRDR-7000 Weather Radar Pilot's Guide The example below demonstrates the WX MAN mode. In the top center picture, the system is in the WX ALL mode at an aircraft altitude of 20,000 feet MSL. In the second center picture, WX MANmode has been selected.This is an elevation slice at the current aircraft altitude (20,000 feet MSL).
