22. For additional practice, clear the flightplan and re-enter all of
the waypoints. Start by depressing and holding the VAS.
23. Carefully speak the words: "START" "NEW" "FLIGHTPLAN".
24. An audio message “Confirm Start New Flight Plan?” should be
heard. Just as with the Direct-To, confirm the command by
double-clicking the VAS within two seconds. The entire
contents of the flightplan should disappear.
25. After Depressing the VAS, re-enter all of the waypoints (for
our example):
"KILO" "HOTEL" "FOXTROT" "DELTA" "ENTER"
"SIERRA" "ALPHA" "GOLF" "ECHO" "SIERRA" "ENTER"
"INDIA" "GOLF" "NOVEMBER" "ENTER"
26. Release the VAS.
27. Examine the flightplan entries and confirm that all of the
sample waypoints were correctly entered.
5.0 Detailed Functional Description
This section provides a detailed description of how the VFS101
operates. For each behavior, a diagram shows the speech patterns
used to activate the command. These diagrams are also shown on the
VFS101 Quick Reference Card.
5.1 VoiceFlight Activation Switch (VAS)
The VFS101 speech-recognition system
accepts speech input only when the
VoiceFlight Activation Switch (VAS) is
depressed. This switch is typically
mounted on the left side of the pilot's
yoke, and labeled VAS or VFS101. (Your
installation may vary.)
Depressing the VAS should result in the
pilot hearing a distinctive “double beep”
sound through the aircraft audio system.
This sound indicates the VFS101 system
is active and awaiting input. Do not begin
speaking until the double-beep is heard.
Releasing the VAS terminates all audio
output from the VFS101 system, and discards any partial entry or
extraneous noise. This behavior can be used in the event of a speech
error to quickly clear the mistake and start over. Releasing the VAS
also cancels any waypoint selections or incomplete airway entries.
