The data undergoes verification by Garmin to confirm accuracy of the content. However, the displayed information should never be understood as being all-inclusive. Pilots must familiarize themselves with the appropriate charts for safe flight. Database Versions The version and area of coverage of each terrain/ obstacle database is shown on the Terrain Database Versions Page, located in the AUX Page Group. Databases are checked for integrity at power-up. If a database is found to be missing and/or deficient, the HTAWS system fails the self-test and displays the HTAWS system failure message. NOTE: The data contained in the terrain and obstacle databases comes from government agencies. Garmin accurately processes and cross-validates the data, but cannot guarantee the accuracy and completeness of the data. The terrain/obstacle databases are contained on a datacard which is inserted in the right-most slot of the 400W/500W Series units. 52 190-00356-30 Rev H
