9. Depress and hold the VAS for at least two seconds. This will
return the VFS101 to normal operations, with the new output
volume level.
7.2 Updating the Navigational Database
It is necessary to update the VFS101 navigational database every 28
days in synchronization with the AIRAC charting cycle. These updates
should be done at the same time as a new navigation data-card is
installed in the Primary GPS (and secondary GPS if so equipped).
It is the pilot's responsibility to ensure that the
correct navigational data is installed on the VFS101.
Failure to use current navigational data may result in
incorrect airway expansion and an inability to enter
some waypoints using the VFS101.
If the VFS101 navigational database and Primary GPS navigation
database do not have the same cycle number, the VFS101 will play an
audio warning message the first time the VAS is depressed after the
unit is powered on. The VAS must remain depressed throughout the
entire message to confirm the message has been heard or it will
repeat. This warning ONLY indicates the GPS navigational database
and the VFS101 navigational databases do not match. This could be
the result of the VFS101
or
the GPS navigational databases not being
current.
The VFS101 is unable to identify the specific situation where both
databases are non-current but have matching cycle numbers. The fact
that the GPS database is not current will be evident on the GPS
startup screens. If the GPS is subsequently updated without a
matching update to the VFS101, audio messages will then be
generated by the VFS101.
Operating the VFS101 with an obsolete navigational database is
permissible, however doing so imposes an operational restriction:
If the navigational database installed on the VFS101 is
not current, the pilot must manually verify the
correctness of each waypoint and airway entered
using the VFS101 by comparison to current
navigational charts.
To update the VFS101 Navigational Database, utilize the following
procedure:
1. Download the navigational database from the “Navigation
Update” section of the VoiceFlight Systems website
(http://www.voiceflight.com) which corresponds to the
Primary GPS navigation database. If the website is unavailable
contact VoiceFlight Systems customer support for assistance.
Contact information can be found in section 8.0 of this
document. The computer used for this should be running a
recent version of Microsoft Windows, Apple OS X or Linux
to insure proper support for the USB flash drive used in step
2.
2. Insert the supplied USB flash drive into a USB port on the
computer. On most systems the flash drive should be
automatically opened (mounted) by the operating system.
Transfer the downloaded navigational database file to the
Flash Drive. If other VoiceFlight files (files with the extension
“.vfs”) exist on the USB drive, erase them. Do not place the
update file into any sub-directories on the flash drive. Eject
