5.2 ICAO Spelling Alphabet
The VFS101 uses the ICAO spelling alphabet (Alpha, Bravo, Charlie,
etc.) for speech recognition. When using the VFS101 to input
navigational information, be sure to use those words shown in the
table below. Non-standard words (Adam, Billy, Fox, Ohh, etc.) will not
be recognized.

If you are having difficulty entering an airport waypoint remember that
airport waypoints may be prefaced with a “K” (Kilo) in the continental
United States or a “P” (Papa) in Alaska and Hawaii. Numbers must be
entered as a string of digits e.g. “Fife Zero Niner”, not “five-hundred
and nine”.
5.3 Title Line
The VFS101 uses the title line of the active flightplan on the primary
GPS to provide feedback on it's activities. When using the VFS101, the
pilot should monitor the title line to confirm that the speech
commands have been correctly recognized. If the VFS101 generates an
error tone, an error message will be displayed on the title line for
several seconds. A list of these messages and their causes is found in
Appendix C.
When the GPS is proceeding Direct-To a waypoint which does not
appear in the active flightplan, the title line is not available (since it is
displaying the Direct-To waypoint.) To allow access to the title line,
the VFS101 will temporarily move this direct-to waypoint to the end
of the flightplan to allow access to the title line, then remove it from
the flightplan when it has finished using the title line.
An active Direct-To targeting a non-flightplan waypoint will also
prevent the pilot from entering the configuration display interface,
adjusting the VFS101 audio output volume, or changing the airway
compression setting (see section 7). To access the title line for
configuration entry, the Direct-To must first be canceled using the
manual controls. (Press Direct-To, then MENU, then ENT.)
