Preface

This manual provides detailed instructions for using the VFS101 Speech Recognition System with Garmin GNS 430 / 530 or 430W / 530W series

GPS units. Please carefully review the complete manual and familiarize yourself with the system before attempting to use the VFS101 in ﬂight.

1.0 Introduction

The VoiceFlight VFS101 is a revolutionary speech-recognition system

that allows pilots to rapidly enter navigational waypoints using their

voice. The system provides accurate speech recognition, and nearly

instantaneous response, for the great majority of pilots and ﬂight

environments. Voice entry of complex ﬂightplans can be performed

approximately ten times faster than is possible with conventional

knob-twisting. The system is speaker independent and operates

without any type of “enrollment” or tuning before use.

For routine ﬂight operations, the VFS101 provides convenient, “hands-

free” entry of Direct-To waypoint destinations directly into the

aircraft's primary Garmin GPS unit. For safety, an audio read-back of

the intended waypoint is presented for conﬁrmation before the new

destination is activated.

The VFS101 also provides the capability to enter complex ﬂight plans

using speech commands. The system typically recognizes waypoint

entries faster than the pilot is able to (clearly) speak them. In addition

to rapid entry of multiple waypoints, the system performs automatic

expansion of airways, also provided via voice entry.

The VFS101 operates on the primary GPS's active ﬂightplan. The

ﬂightplan's title line is continually updated to display new waypoints as

they are added to the ﬂightplan and to display error messages

describing any problems that are encountered.

A suite of voice commands are available for editing the ﬂightplan, to

correct errors, or accommodate routing changes. The context of

editing operations is displayed on the ﬂightplan title line.

The VFS101 system does not alter or interfere with manual operation

of the aircraft GPS. If the pilot experiences diﬃculties or confusion

while utilizing the VFS101, conventional manual operations are readily

available.

The VoiceFlight Activation Switch (VAS) is typically mounted on the

pilot yoke and is activated by the pilot when speech commands are

provided to the VFS101. The VFS101 will not recognize speech, or

transmit updates to the GPS units, unless the VAS is depressed.

The GNS 430 / 530 and GNS 430W / 530W series GPS units have

historically been limited to a maximum of 31 waypoints per ﬂightplan.

However, when a GNS 430W / 530W is updated to Main Software

Version 5.00 or later, this limit is expanded to 100 waypoints. In this

document, this limitation will be referred to as “31 or 100 waypoints”

with the implicit dependency on the Main Software version installed

into the GPS unit.

1.1 Operating Limitations

"VFS101 editing operations are limited to the en-route section

of the active ﬂightplan on the primary GPS.

"The VFS101 will not allow editing of an active navigation leg.

"All VFS101 operations are suspended when an approach is

loaded into the active ﬂightplan. VFS101 operations will be

restored after the approach is removed.

"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 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.

"Each individual pilot should complete the Pilot Qualiﬁcation

procedures described in Section 4.2 before attempting to use

the VoiceFlight unit for actual in-ﬂight navigation. This is to

ensure the VFS101 is able to safely recognize the pilot's voice,

and that the pilot is familiar with the VFS101's operation.

2.0 Operational Overview

This section includes the key information needed to operate the

VFS101. A more detailed description of VFS101 functions can be

found in section 5 of this guide.

"The system recognizes speech only while the VoiceFlight

Activation Switch (VAS) is depressed.

"Upon depressing the VAS, do not begin speaking until the

System Ready "Double Beep" is heard. If the "double beep" is

not heard, release the switch and attempt to identify the

problem.

"The VFS101 only recognizes words from the ICAO spelling

alphabet, and only when they are used in the correct syntax.

Using the wrong words, or in the wrong order will not work.

The ICAO alphabet can be found in Section 5.2.

"If a speaking mistake is made, momentarily release the VAS,

then depress it again before attempting to repeat the desired

phrase.

"Audio output from the VFS101 stops upon VAS release.

Prematurely releasing the VAS will prevent VFS101 Audio

feedback, such as conﬁrmation read-back of Direct-To

commands.

"When entering waypoints into the active ﬂightplan, individual

legs may be up to 250 nautical miles in length. Cross country

ﬂightplans can be built from sequences of individual 250

nautical mile legs.

Page 2 / 25

"Direct-To destinations may be up to 1,000 nautical miles from

the aircraft's position if they are an airport or VOR, up to 250

nautical miles if they are any other waypoint type, or an

unlimited distance if they are present in the active ﬂightplan

on the primary GPS.

"The VFS101 is designed to recognize only the currently eligible

waypoints. If an intended waypoint is repeatedly mis-

recognized as some other waypoint, it is likely that the

intended waypoint is not currently eligible. Potential causes

include:

!Missing preﬁx character on an airport name (e.g. “K” on

alphabetic airports within the continental U.S.)

!An airway is active, and spoken waypoint is not located on

that airway (Note: airports are never on airways)

!The waypoint is located outside of the current search

radius. This is 250 nautical miles for most commands, and

1,000 nautical miles for Airport and VOR Direct-Tos.

!The waypoint is missing from the VFS101 navigation

database

"During initial familiarization with the VFS101 unit, some pilots

have a tendency to release the VAS sooner, and more

frequently, than is necessary. This tendency is reduced as the

pilot gains more experience with the unit.

"Upon entering a Direct-To waypoint, conﬁrm that the

destination identiﬁer and the track displayed on the map page

are correct.

"The blinking cursor shown on the GPS does NOT represent

VFS101 selection of a waypoint. The selection of a waypoint is

shown by asterisks surrounding the waypoint on the ﬂightplan

title line.

"If the VFS101 or GPS units exhibit anomalous behavior turn

oﬀthe VFS101 using the dedicated circuit breaker or power

switch.

"The VFS101 will shut down if the VAS is depressed and

released ﬁve times without successfully recognizing speech.

This is for safety reasons. To re-start the VFS101, remove

power from the VFS101 (not the GPS) using the dedicated

VFS101 circuit breaker or switch. Wait at least 5 seconds then

re-apply power. The VFS101 will restart in approximately 20

seconds.

"When entering a ﬂightplan into the GPS, it is beneﬁcial to have

the active ﬂightplan displayed on the primary GPS. This is

accessed by pressing the FPL button.

"When a VFS101 error tone in heard, examine the title line of

the active ﬂightplan on the primary GPS. An error message

will be displayed there for several seconds. See Appendix C

for a listing of these messages and their causes.

"The internal processor of the GNS 430 / 530 series GPS units

is considerably slower. On these units, VFS101 responses may

be delayed for a second or two in speciﬁc circumstances (e.g.

processing the ﬁrst speech command with a long ﬂightplan).

3.0 VFS101 Interconnect Diagram

The VFS101 system consists of a single 3.3 in x 5.5 in x 1 in, unit which

is mounted behind the aircraft's instrument panel. This unit has a

single DB-25 connector and connects to other aircraft systems as

shown in the VFS101 System Block Diagram.

All waypoints input through the VFS101 appear on the primary GPS.

The optional secondary GPS is connected to allow the pilot to

continue to use the crossﬁll functionality to send ﬂightplans from one

GPS to the other.

The database update port is a standard USB jack which accepts USB

ﬂash storage devices, used to install new navigational data.

The switch/fuse or pullable breaker can be used to disable the VFS101

in the event it exhibits anomalous behavior, or to restart the VFS101

after a shutdown.

The VFS101 audio output is directly connected to the audio panel

intercom system.

4.0 Getting Started

This section contains examples of how to enter Direct-To commands

and a short ﬂightplan. If diﬃculties are encountered during any of the

following exercises, please refer to the trouble-shooting section of

this manual (sec. 6.0), consult with your authorized avionics installer,

or contact VoiceFlight Systems technical support.

4.1 Cautions

"After depressing the VoiceFlight Activation Switch (VAS), do

not begin speaking until the double-beep is heard.

"Conﬁrm all airway expansions prior to use.

"Upon entering a Direct-To waypoint, conﬁrm that the

destination identiﬁer and the track displayed on the map page

are correct.

"If the VFS101 or GPS unit exhibit anomalous behavior turn oﬀ

the VFS101 using the dedicated circuit breaker or power

switch.

"The VFS101 navigation database must be updated every 28

days in synchronization with the AIRAC charting cycle.

"The blinking cursor shown on the GPS does NOT represent

VFS101 selection of a waypoint. The selection of a waypoint is

shown by asterisks surrounding the waypoint on the ﬂightplan

title line.

"Do not initiate conventional crossﬁll or manual ﬂightplan

editing operations while the VAS is depressed.

"While inserting waypoints on GNS 430W / 530W series GPS

units, the VFS101 may insert temporary waypoints at the

bottom of the ﬂightplan. If these are not automatically

removed, discontinue VFS101 operations and remove them

manually.

4.2 Pilot Qualiﬁcation Procedure

The pilot qualiﬁcation procedure is designed to conﬁrm that the

VFS101 is able to recognize a given pilot's voice and to familiarize the

pilot with the system. Each pilot should complete pilot qualiﬁcation

before using the VFS101 for in-ﬂight entry of navigational data.

Complete the procedures described in sections 4.3 and 4.4 twice

each, once on the ground, and the second time in ﬂight while ﬂying

under VFR conditions in an environment where the procedure can be

safely completed. The qualiﬁcation is complete when the procedures

can be performed without errors.

4.3 Activating a Direct-To Waypoint

For this exercise, select two or three nearby waypoints and record

their identiﬁers exactly as would be used manually with the Garmin

GPS units. The selected waypoints must be within 1,000 nautical miles

for airport identiﬁers or VORs, and within 250 nautical miles for all

other waypoint types.

For illustration, this document uses two identiﬁers: Chicago's O'Hare

International airport "KORD" and the "SAGES" navigational ﬁx near

KHFD. This example assumes the aircraft is located at KHFD in

Hartford, CT.

Page 5 / 25

It will be helpful for this initial example to write down the ICAO

alphabet translation for the selected identiﬁers. (The ICAO alphabet

appears in the Detailed Functional Description section of this

document, and on the VFS101 Quick Reference Card).

For our example waypoints:

KORD -> Kilo Oscar Romeo Delta

SAGES -> Sierra Alpha Golf Echo Sierra

Note:

Initial familiarization is performed in a safely positioned

stationary aircraft without the engine running.

Position the aircraft in a location where the GPS antennas have an

unobstructed view of the sky. Apply power to the audio panel, the

primary Garmin GPS unit, and the VFS101 unit.

Allow the GPS unit to complete its initialization and self-test.

Acknowledge the initial test screens by pressing the ENT button. Wait

for the GPS to acquire satellites. The VFS101 will complete its

initialization before the GPS units are ready.

From the pilot seat, connect a standard aviation headset to the pilot

headset jacks. Place the headset microphone close to your lips and

adjust the audio panel for a comfortable sidetone volume.

Adjust the primary GPS unit to display the ﬁrst navigation page. This

can be accomplished by depressing the CLR button for a full two

seconds, as well as by a variety of other methods.

The VoiceFlight Activation Switch (VAS) is located on the pilot yoke

and must be depressed when speaking to the VFS101 system. Examine

the switch labels to conﬁrm the VAS location. Always use extra

caution to insure that the VAS is utilized, and not the radio

transceiver Push-To-Talk switch.

Momentarily depress and hold the VAS. A "double-beep" should be

heard through the headset indicating that the VFS101 is operating and

ready to recognize speech.

When utilizing the VFS101, do not begin speaking unless the system-

ready "double-beep" is heard. Instead, release the VAS and attempt to

determine the cause of the problem.

Attempt to initiate a Direct-To operation on the primary GPS using

the selected sample waypoint. For illustration, this document uses

KORD. You should substitute an airport identiﬁer or VOR identiﬁer

within 1,000 nautical miles of the current aircraft location.

1. Depress the VAS (and do not release it until instructed).

2. Clearly and distinctly say exactly the following words:

(substituting a waypoint identiﬁer near the current aircraft

location)

"DIRECT" "KILO" "OSCAR" "ROMEO" "DELTA"

"ACTIVATE"

Direct-To commands begin with the word “DIRECT” (not

“Direct-To”), are followed by the spelling of the intended

waypoint and end with the word “ACTIVATE”.
