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. 4.9.1 Garmin GWX 68 Radar Description The Garmin GWX 68 Airborne Color Weather Radar is a four color digital pulsed radar with 6.5 kilowatts of power. It combines excellent range and adjustable scanning profiles with a high-definition target display. The pulse width is four microseconds on all ranges except the 2.5 NM range. The GWX 68 uses a one microsecond pulse width at this range to reduce the smearing of targets on the display. This allows better target definition at close range. To focus radar scanning on specific areas, Sector Scanning offers pilot- adjustable horizontal scan angles of 20º, 40º, 60º, or 90º. A vertical scanning function helps to analyze storm tops, gradients, and cell buildup activity at various altitudes. Other features include: • Extended Sensitivity Time Control (STC) logic that automatically correlates distance of the return echo with intensity, so cells do not suddenly appear to get larger as they get closer. • WATCH™ (Weather Attenuated Color Highlight) which helps identify possible “shadowing” effects of short-range cell activity – identifying areas where radar return signals are weakened, or attenuated, by intense precipitation (or large areas of lesser precipitation) and may not fully reflect the “storm behind the storm.” • Weather Alert that looks ahead for intense cell activity in the 80-320 NM range, even if these ranges are not being monitored. 4.9.1.1 Principles of Pulsed Airborne Weather Radar The term RADAR is an acronym for RAdio Detecting and Ranging. Pulsed radar locates targets by transmitting a microwave pulse beam that, upon encountering a target, is then reflected back to the radar receiver as a return “echo.” The microwave pulses are focused and radiated by the antenna, with the most intense energy in the center of the beam and decreasing intensity near

The same antenna is used for both transmitting and receiving. The returned signal is then processed and displayed on the G500 MFD. Radar detection is a two-way process that requires 12.36 micro-seconds for the transmitted microwave pulses to travel out and back for each nautical mile of target range. It takes 123.6 micro-seconds for a transmitted pulse to make the round trip if a target is 10 NM away. The GWX 68 weather radar should be used to avoid severe weather, not for penetrating severe weather. The decision to fly into an area of radar targets depends on target intensity, spacing between the targets, aircraft capabilities and pilot experience. Pulse type weather radar detects only precipitation, not clouds or turbulence. The display may indicate clear areas between intense returns, but this does not necessarily mean it is safe to fly between them.\ Only Doppler radar can detect turbulence. 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. 4.9.1.2 Antenna Beam Illumination It is important to understand the concept of the antenna beam illumina- tion. The radar beam is much like the beam of a spotlight. The farther t\ he beam travels, the wider it gets. The radar is only capable of “seeing\ ” what is inside the boundaries of the beam. Figure 4-56 Radar Beam from 12 inch Antenna The vertical dimensions of the radar beam are shown in the figure above and the same holds true for the horizontal dimensions. In other words, the beam will be as wide as it is tall. Note that it is possible not to see \ areas of precipitation on the radar display because of the antenna tilt setting. With the antenna tilt set to zero in this illustration, the beam overshoots the precipita-
