  • Page 36: Weather

    GSR 56 and FIS-B weather from a GDL 88. The GTN 7XX can display weather radar from a Garmin GWX system or from selected 3rd party radars. Only one weather radar system may be interfaced to the system. For detailed information on the operation of 3rd party radars, refer to their specific documentation.

  • Page 37: Antenna Beam Illumination

    Airborne weather radar has other capabilities beyond weather detection. It also has the ability to detect and provide distance to objects on the ground, such as, cities, mountains, coastlines, rivers, lakes, and oceans. 5.1.2 Antenna Beam Illumination It is important to understand the concept of the antenna beam illumination. The radar beam is much like the beam of a spotlight.

  • Page 38: Radar Signal Attenuation

    5.1.3 Radar Signal Attenuation The phenomena of weather attenuation needs to be kept in mind whenever operating the weather radar. When the radar signal is transmitted, it is progressively absorbed and scattered, making the signal weaker. This weakening, or attenuation, is caused by two primary sources, distance and precipitation. Attenuation because of distance is due to the fact that the amount of radar energy at a distance from the antenna is inversely proportional to the square of the distance.

  • Page 39: Radar Signal Reflectivity

    5.1.4 Radar Signal Reflectivity 5.1.4.1 Precipitation Precipitation or objects more dense than water, such as earth or solid structures, will be detected by the weather radar. The weather radar will not detect clouds, thunderstorms or turbulence directly. It detects precipitation associated with clouds, thunderstorms, and turbulence.

  • Page 40: Ground Returns

    5.1.4.2 Ground Returns The intensity of ground target returns depends upon the angle at which the radar beam strikes the ground target (Angle of Incidence) and the reflective properties of that target. The gain can be adjusted so shorelines, rivers, lakes, and cities are well defined.

  • Page 41: Radar Operating Distance (Gtn 7Xx Only)

    Figure 5-4 Angle of Incidence A smaller incident angle gives the radar a larger detectable range of operation and the target display will show a higher intensity. Since more radar energy is reflected back to the antenna with a low incident angle, the resulting detectable range is increased for mountainous terrain.

  • Page 42: Basic Radar Antenna Tilt Setup (Gtn 7Xx Only)

    MPEL Boundary 11’ for 12” antenna Figure 5-5 MPEL Boundary Basic Radar Antenna Tilt Setup (GTN 7XX Only) The following discussion is a simple method for setting up the weather radar antenna tilt for most situations. It is not to be considered an all encompassing setup that will work in all situations, but this method does provide good overall parameters for the monitoring of threats.

  • Page 43: Radar Weather Mapping And Interpretation (Gtn 7Xx Only)

    If the aircraft is above 29,000 feet, be cautious of any target return that gets to 30 NM or closer. This is likely a thunderstorm that has a top high enough that the aircraft cannot fly over it safely. If the aircraft altitude is 15,000 feet or lower, set the displayed range to 60 NM.
