Navigation Updates

VFS101 navigation database updates are currently free of charge. VoiceFlight Systems develops its navigational database updates from U.S. government data. This data covers the United States (including Alaska, Hawaii and overseas protectorates and territories). Coverage of other areas is not complete and should not be relied on.

It is the pilot's responsibility to update the VFS101 with new navigational database every 28 days, in accordance with the AIRAC charting cycle. This data is used to improve the speech recognition performance of the system, and to expand Victor Airways.

The navigation update files are protected by robust digital signatures to preclude any possibility of corruption during transfer and installation. Each navigation update file has a unique digital checksum, listed to the right. After installation of the update, compare the database checksum listed here to the database checksum displayed by the VFS101 unit. They should be identical.

Download and installation of the navigation database is described in the VFS101 Pilot's Guide, section 7.2.
