Older Updates
VoiceFlight Systems developed its navigational database updates from U.S. government data. This data covered the United States (including Alaska, Hawaii and overseas protectorates and territories). Coverage of other areas was not complete and should not be relied on.
It is the pilot's responsibility to update the VFS101 with a 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.
VFS101 Discontinued
As noted on the Home Page, VoiceFlight Systems LLC discontinued the manufacture, sales, and support of the VFS101 product on September 22, 2014 and will not be posting any additional VFS101 Nav Updates beyond Cycle 1410 listed below.
In hopes of keeping the existing VFS101 units running a while longer, VoiceFlight Systems has developed a Windows application intended to allow VFS101 users to generate their own Nav Updates without further VoiceFlight assistance. Details on this Window application are provided on the VFS101 User Nav Updates page.
In any event, users are urged not to attempt continued VFS101 operations with a Nav Database that does not match the one installed in the GPS. Mismatched databases puts a much heavier load on both the VFS101 and the GPS, which may lead to operational or even safety issues. In these instances, the VFS101 plays a WARNING message which should be taken seriously.
Older Navigation UpdatesDownload and installation of the navigation database is described in the VFS101 Pilot's Guide, section 7.2, and is illustrated in a video demonstration available on the Support Page. |
