Safety notices

The Altair documentation is an essential component of the equipment and should carefully be

stored with the aircraft log book.

•The pilot is ultimately responsible for all ﬂight decisions and for operating the aircraft safely

at all times.

•This equipment does not remove the need to maintain an effective lookout.

•Continue to observe the airspace and do not rely on TR-DVS (or FLARM) to announce all

objects in the airspace!

•If possible, TR-DVS is to be installed as ‘portable equipment’ with an autonomous power

supply.

•Read the FLARM operating instructions carefully — in particular the Section ‘Restrictions

on operation’ below. TR-DVS is unable to report on objects that are not detected by FLARM.

•Improper installation or misuse of TR-DVS may result in degraded performance of TR-DVS

or to equipment to which it is connected.

•The safety notices must be observed, in particular attention must be given to |notes and

kwarnings.

1 GENERAL DESCRIPTION

1 General Description

1.1 Overview

•TR-DVS is an acoustic reporting system, which produces airspace trafﬁc refer-ences and

collision warnings from FLARM, primarily via speech over a loud-speaker or headset.

•TR-DVS is small, easy to use, with a simple user interface and can be built into small

instrument panels.

•TR-DVS integrates with FLARM and receives GPS and aircraft obstacle data. The object

data announced by FLARM are converted to accoustic caution or warning messages. These

messages contain data pertaining to the threat level, direction, height, type of aircraft and

distance to the object. For obstacles, the messages contains the type of threat and distance.

•TR-DVS can announce several objects with different hazard potentials. FLARM announces

a maximum of ﬁfteen objects in the current Version (3.0).

•TR-DVS announces the most important four objects

1.2 SD Card

•TR-DVS can be conﬁgured and its ﬁrmware updated via an SD card.

•Flight logs can be read from the FLARM recorder and saved to the SD card.

•TR-DVS can be used safely without an SD card.

1.3 Audio

•TR-DVS is able to mix other audio signals (Vario, COM loudspeaker and Headset) and send

them to a loudspeaker or headset alongwith the generated speech messages.

•The audio signal of the Vario is lowered during generated speech.

•The COM audio signals (radio, channel A and/or B) have higher priority than the generated

messages. Unimportant messages are delayed until the radio transmission is complete;

after a short pause the message is then spoken. Important messages are spoken imme-

diately even whilst receiving a radio transmission - however at reduced (1/4) volume. If a

radio transmission arises during a generated message, then the volume of the generated

speech is lowered immediately by 1/4.

•TR-DVS has two independent audio channels, each of which are composed of a mixer and

an ampliﬁer. This allows the separate use of a loudspeaker and headset.

2 MESSAGES

2 Messages

2.1 Message classes

TR-DVS uses 4 message classes:

Class Preﬁx tone Description

Message None This class is used only for pure trafﬁc advisory messages in

mode 1.

Reference “Ping” FLARM collision warnings alarm level 1 (18 sec).

FLARM voltage supply.

Battery warning ﬁrst stage.

Caution Double beep FLARM collision warnings alarm level 2 (13 sec).

FLARM functionality restricted.

Warning Siren FLARM collision warnings alarm level 3 (8 sec).

FLARM malfunction.

Airframe warning.

Battery warning second stage.

The messages are prioritised according to its message class (importance) and treated accordingly,

examples:

•If a message of the class “reference” is being spoken and a message of a higher priority

arises, then the less important message is interrupted and the more important one is spoken

immediately.

•For repeating messages, if the REP key is pressed, messages of the class “warning” are

sent before messages of the class “caution”.

2.2 Message format

2.2.1 Obstacles

Collision points with obstacles are calculated with the tangentials to the current ﬂight path. The re-

ported obstacle is thus always in the current direction of movement. The currently most dangerous

obstacle is always reported.

Obstacle messages have the format:

<Audio warning>“Obstruction“ <Distance>

Distance

The distance is announced in hectometres, “One“ corresponds to 100m, “Four“ to 400m. At high

approach speeds distances over 1000m are also announced (“One Two“ = 1200m). Distances

below 50m are not announced. Distances are rounded off; 50-149m is announced as “One“, 150-

249m as “Two“, etc.

2.2.2 Objects

Object messages have the format: <Audio warning> <Direction> <Altitude> <Object Type>

TR-DVS Pilot’s Manual •DVS-P-EN 2 - ??

2 MESSAGES

Direction

The direction is announced according to the hour hand position (one o’clock up to twelve o’clock)

on a clockface. E.g.:

•Twelve o’clock: ahead

•Six o’clock: behind

•Three o’clock: right

•Nine o’clock: left

Altitude

The altitude of the object is announced relative to one’s own altitude in six increments. The altitude

information is omitted for less than six degrees above or below the horizon. “Higher“ or “Lower“ is

announced between six and twelve degrees. “High“ or “Low“ is announced for more than twelve

degrees. “Above“ or “Below“ will be announced if the object is in a 300m cylinder above or below

the aircraft.

Object type

The object type corresponds to the type of the nearby aircraft. E.g. “Glider“, “Helicopter“ or

“Powered Aircraft“ ; unknown object types are announced as “Trafﬁc“.

Distance

The distance is announced in hectometres, “One“ corresponds to 100m, “Four“ to 400m. At high

approach speeds distances over 1000m are also announced (“One Two“ = 1200m). Distances

below 50m are not announced. Distances are rounded off; 50-149m is announced as “One“, 150-

249m as “Two“, etc.

2.2.3 System messages

System messages are generated if the system’s operational readiness is partly restricted or if the

system has failed. TR-DVS produces the following system messages:

•FLARM error status, GPS status, Tx and power status

•Airframe warning

•Battery monitoring

•Optional additional messages

FLARM system messages

FLARM system messages always mean a system failure. Example:

<Audio warning>“FLARM Error No GPS“

Inadequate GPS reception. This message is only announced once in the air. This message is

repeated every 10 seconds on the ground.

All other FLARM system messages need not be expected with a functioning system and indicate a

defect in the device.

2 MESSAGES

2.3 Message ﬁlter

Depending upon the operating mode, trafﬁc references and collision warnings are ﬁltered in accor-

dance with the FLARM Alarm Level. FLARM understands four Alarm Levels:

FLARM Alarm Level Description

0 No potential collision risk, thus pure trafﬁc references.

1 (Minor) A potential collision risk is given 18 seconds before the time of the

estimated potential collision.

2 (Important) A potential collision risk is given 13 seconds before the time of the

estimated potential collision.

3 (Urgent) A potential collision risk is given, 8 seconds before the time of the

estimated potential collision.

Illustration of the message ﬁlter effects based on the operating mode:

Mode What is ﬁltered Warning time Description

1 Nothing >18 Seconds All objects that FLARM announces are an-

nounced.

2 AlarmLevel 0 18 Seconds Only objects with potential hazard are an-

nounced (The output corresponds to the

FLARM indicators)

3 AlarmLevel 0 and

≤13 Seconds Only objects with FLARM hazard potential

important and urgent are announced.

4 AlarmLevel 0, 1

and 2

≤8 Seconds Only objects with FLARM hazard potential

urgent are announced.

5 All messages No warning No announcements are made. This mode is

only temporary, after 5 minutes the system

reverts to the last active mode.

After switching on on the equipment is in mode 2. Modes above 2 should be selected only in

special cases and with caution.

2.4 Acknowledge messages

Messages can be acknowledged with the ACK key (Acknowledge). Messages that are not ac-

knowledged will be repeated after a certain time. The repeat time for unacknowledged messages

depends on the level of risk.

Messages with high level of risk are repeated more frequently, those with low risk less frequently.

If the hazard potential of an object increases, any acknowledgement of that object becomes invalid

and a new message with the updated object status is generated immediately. If the hazard potential

is reduced for an object that has already been acknowledged, the message is regarded as having

been acknowledged.

The acknowledgement always refers to the currently announced object. It becomes invalid as soon

as the object leaves the reception range of TR-DVS.

Acknowledgements for obstacles are only valid as long as the obstacle constitutes a hazard.

TR-DVS Pilot’s Manual •DVS-P-EN 4 - ??

2 MESSAGES

2.5 Repeat messages

Acknowledged messages can be replayed by pressing the REP key (Repeat). Message contents

(direction, altitude, aircraft type and distance) are constantly updated.

If you have forgotten to acknowledge a message it can be replayed with REP and then acknowl-

edged.
