WARNING: NEXRAD weather data is to be used for long-range planning purposes only. Due to inherent delays in data transmission and the relative age of the data, NEXRAD weather data should not be used for short-range weather avoidance. WARNING: The Garmin G1000, as installed in Cessna Nav III aircraft, has a very high degree of functional integrity. However, the pilot must recognize that providing monitoring and/or self-test capability for all conceivable system failures is not practical. Although unlikely, it may be possible for erroneous operation to occur without a fault indication shown by the G1000. It is thus the responsibility of the pilot to detect such an occurrence by means of cross-checking with all redundant or correlated information available in the cockpit. WARNING: For safety reasons, G1000 operational procedures must be learned on the ground. WARNING: The United States government operates the Global Positioning System and is solely responsible for its accuracy and maintenance. The GPS system is subject to changes which could affect the accuracy and performance of all GPS equipment. Portions of the Garmin G1000 utilize GPS as a precision electronic NAVigation AID (NAVAID). Therefore, as with all NAVAIDs, information presented by the G1000 can be misused or misinterpreted and, therefore, become unsafe. WARNING: To reduce the risk of unsafe operation, carefully review and understand all aspects of the G1000 Pilots Guide documentation. Thoroughly practice basic operation prior to actual use. During ight operations, carefully compare indications from the G1000 to all available navigation sources, including the information from other NAVAIDs, visual sightings, charts, etc. For safety purposes, always resolve any discrepancies before continuing navigation. WARNING: The illustrations in this guide are only examples. Never use the G1000 to attempt to penetrate a thunderstorm. Both the FAA Advisory Circular, Subject: Thunderstorms, and the Airmans Information Manual (AIM) recommend avoiding by at least 20 miles any thunderstorm identied as severe or giving an intense radar echo. CAUTION: The GDU 1040 PFD/MFD displays use a lens coated with a special anti-reective coating that is very sensitive to skin oils, waxes, and abrasive cleaners. CLEANERS CONTAINING AMMONIA WILL HARM THE ANTI-REFLECTIVE COATING. It is very important to clean the lens using a clean, lint-free cloth and an eyeglass lens cleaner that is specied as safe for anti-reective coatings.

NEXRAD Limitations Certain limitations exist regarding the NEXRAD radar displays. Some, but not all, are listed here: NEXRAD base reectivity does not provide sufcient information to determine cloud layers or precipitation characteristics (hail vs. rain, etc). An individual NEXRAD site cannot depict high altitude storms at close ranges, and has no information about storms directly over the site. The resolution of displayed NEXRAD data is 2 kilometers. Therefore, when zoomed in on the display, each square block is 2 kilometers. The intensity level reected by the square will be the highest level sampled within the 2 kilometer square area. ECHO TOP press the ECHO TOP softkey to show the location, elevation, and direction the highest radar echo. This may not indicate the top of a storm or clouds, only the highest radar return echo. ECHO TOPS cannot be displayed along with NEXRAD and CLOUD TOPS. When ECHO TOPS is activated, NEXRAD and CLOUD TOPS are removed. Refer to the Legend for a description of the ECHO TOPS coding. The display is updated every 7.5 minutes. CLD TOP press the CLD TOP softkey to show the cloud top altitude determined from satellite imagery. The display is updated every 15 minutes.

11.1 REVERSIONARY MODE

Should a system detected failure occur in either display, the G1000 automatically enters reversionary mode. In reversionary mode, critical ight instrumentation is combined with engine instrumentation on the remaining display. Minimal navigation capability is available on the reversionary mode display.
Reversionary display mode can also be manually activated by the pilot if the system fails to detect a display problem. The reversionary mode is activated manually by pressing the red DISPLAY BACKUP button on the bottom of the audio panel (GMA 1347). Pressing the red DISPLAY BACKUP button again deactivates reversionary mode.
NOTE: The Cessna Pilots Operating Handbook (POH) always takes precedence over the information found in this section.

When a COM tuning failure is detected by the system, the emergency frequency (121.500 MHz) is automatically loaded into the active frequency eld of the COM radio for which the tuning failure was detected. In the event of a dual display failure, the emergency frequency (121.500 MHz) automatically becomes the active frequency to the pilot through the pilot headset.

SECTION 12: ANNUNCIATIONS & ALERTS
NOTE: The Cessna aircraft Pilots Operating Handbook (POH) supersedes information found in this document.
(WARNING, CAUTION, or ADVISORY). By pressing the softkey annunciation, the pilot acknowledges awareness of the alert. The softkey then returns to the previous ALERTS label. If alerts are still present, the ALERTS label will be displayed in inverse video (white background with black text). The pilot can press the ALERTS softkey a second time to view alert text messages. System Annunciations: Typically, a large red X appears in windows when a failure is detected in the LRU providing the information to the window. See the G1000 System Annunciations section for more information. Audio Alerting System: The G1000 system issues audio alert tones when specic system conditions are met. See the Alert Levels Denitions section for more information.
The G1000 Alerting System conveys alerts to the pilot using a combination of the following items: Annunciation Window: The Annunciation window displays abbreviated annunciation text. Text color is based on alert levels described later in the Alert Levels Denitions section. The Annunciation window is located to the right of the Altitude and Vertical Speed windows on the display. All Cessna Nav III annunciations can be displayed simultaneously in the Annunciation window. A white horizontal line separates annunciations that are acknowledged from annunciations that are not yet acknowledged. Higher priority annunciations are displayed towards the top of the window. Lower priority annunciations are displayed towards the bottom of the window. Alerts Window: The Alerts window displays alert text messages. Up to 64 prioritized alert messages can be displayed in the Alerts window. Pressing the ALERTS softkey displays the Alerts window. Pressing the ALERTS softkey a second time removes the Alerts window from the display. When the Alerts window is displayed, the pilot can use the large FMS knob to scroll through the alert message list. Softkey Annunciation: During certain alerts, the ALERTS softkey may appear as a ashing annunciation to accompany an alert. The ALERTS softkey assumes a new label consistent with the alert level

12.1 ALERT LEVEL DEFINITIONS
The G1000 Alerting System, as installed in Cessna Nav III aircraft, uses three alert levels. WARNING: This level of alert requires immediate pilot attention. A warning alert is accompanied by an annunciation in the Annunciation window. Warning text appearing in the Annunciation window is RED. A warning alert is also accompanied by a ashing WARNING softkey annunciation, as shown in Figure 12-2. Pressing the WARNING softkey acknowledges the presence of the warning alert and stops the aural tone, if applicable. CAUTION: This level of alert indicates the existence of abnormal conditions on the aircraft that may require pilot intervention. A caution alert is accompanied by an annunciation in the Annunciation window. Caution text appearing in the Annunciation window is YELLOW. A caution alert is also accompanied by a ashing CAUTION softkey annunciation, as shown in Figure 12-3. Pressing the CAUTION softkey acknowledges the presence of the caution alert. MESSAGE ADVISORY: This level of alert provides general information to the pilot. A message advisory alert does not issue annunciations in the Annunciation window. Instead, message advisory alerts only issue a ashing ADVISORY softkey annunciation, as shown in Figure 12-4. Pressing the ADVISORY softkey acknowledges the presence of the message advisory alert and displays the alert text message in the Alerts window.
