1. GENERAL INFORMATION:
Thankyou for purchasing the LX Colibri Data Logger. You will find the unit an accurate, reliable and a
valuable aid to your gliding pursuits. The LX Colibri Logger is an FAI approved flight logger/recorder. The
unit is extremely small and practical (55x100x32mm). The Colibri is operated via seven keys identified by
symbols. All the data and flight information is displayed on a 2x8 character LCD matrix display. A BNC
connector is used to connect the GPS antenna to the unit. The instrument is turned on by inserting the
power lead (telephone type connector) into the appropriate socket on the Colibri.

2. CONTROL KEYS
All necessary data input and manipulation can be done using the seven keys as shown below:
•DOWN arrow
•UP arrow
•RIGHT arrow
•LEFT arrow
•ENTER
•ESCAPE
•EVENT
The unit has four main menus. On power up
the GPS STATUS page is displayed. Pressing
consecutively the right arrow key displays the
NAVIGATION page, then the SETUP menu
and finally the VIEW LOGGER menu. Pressing
the left arrow returns to the previous menu.
When power is applied the Colibri will display the program version followed by the serial number of the
unit and the owner/pilots name for 20 seconds.
GPS STATUS menu - After the initial start up procedure the logger automatically switches to this menu
and commences acquiring satellite fixes. If the aerial is not connected or the aerial is covered by
obstacles, such as buildings, then GPS BAD, SAT = 0 will be displayed. Satellite acquisition time from a
cold start is under 60 seconds. A warm start is typically 30-seconds.
NAVIGATION menu – From the GPS STATUS menu pressing the right arrow brings up the
NAVIGATION menu screen. This shows bearing, track, distance and the first four letters of the selected
turnpoint. Pressing ESCAPE will cause the glider’s ground speed to be displayed in place of the
turnpoint’s name. Turnpoints, which are stored in the database can be selected and also edited as
required from this screen. Pressing the right arrow again takes you to the;
SETUP menu- This page is not used during flight. It is normally used prior to the flight to define the
logger and task parameters. All pilot and glider data are defined in this menu. From this menu pressing
the LEFT arrow will return to the Navigation screen or the RIGHT arrow will lead to the VIEW LOGGER
menu.
ESC ENTER
EVENT

Page: 4
VIEW LOGGER menu – This is selected for flight analysis after landing. Flights made with the logger are
stored in the unit (up to 100hrs depending on logging parameters) and the information is retained even
when the power is switched off.Flights can be analysed via the Colibri’s screen (after landing) without
the need to transfer flight data to a PC. This menu will not be displayed if there are no flights stored in
the logger.
All four main menus have sub-menus . To enter a sub menu use the vertical arrows. A detailed
description of the sub-menus is contained further on in the manual. It is recommended you read this
manual whilst referring to the menu structure diagram at the back of this manual.
The ENTER key always starts the edit procedure and confirms options selected or the data entered.
The ESCAPE key has two functions; go back a step in the menu and to accept the whole row in the
editing procedure. Also the ESCAPE key cycles between the three navigation screens in the navigation
menu. During flight this key starts the wind calculation procedure when pressed in the navigation page.
3. GPS STATUS menu
This menu is active after the instrument is switched on. There is no edit function, as this menu contains
no user definable data. This means the data can only be read from the display. By using the UP and
DOWN arrows the following pages of the GPS STATUS menu are displayed:
GPS OK
SAT=6
GPS status and number of satellites acquired
LAT N 45
00.12
LON E016
45.15
Coordinates of your current position
ALTITUDE
230m
Altitude referenced to the ISA 1013 Hpa pressure level
12:13:44
12.05.98
Current Time/Date
BAT=12.1
DOP =3.3
Battery voltage and DOP (Dilution of Position. Which is a measure
of the accuracy of the GPS position. The lower the number the better)
LOG:STOP
Mem89.6h
Recording status; STOP or RUN is displayed and the Logger Recording Capacity in hours.
Do not switch off the logger at the end of a flight until LOG:STOP is displayed.

Page: 5
NOTE: The logger capacity figure displayed on the above screen doesn’t indicate the remaining portion
of unused memory ! It displays the total memory available for flight recording, which depends upon the
logging time interval and additional data options selected for recording. As old data is automatically
overwritten by new data (ie. the current flight) you don’t need to clear the memory prior to flight.
Hence, after a flight you will find the logger memory number displayed has remained unchanged.
However, changing the recording interval or selecting additional data recording options (see section
5.1.d of the manual) will change the amount of memory available and change the value displayed.
4.0 NAVIGATION MENU
This menu allows in-flight navigation to the selected turnpoint and also editing of the turnpoint data. A
typical navigation screen looks like this.123t CUND
126b235km
123°
°°
°is track, 126°
°°
°bearing, 235km is the distance to the TP and CUND is the first four letters of the
turnpoint (designator). The Colibri counts down the distance to a TP in 1km increments, except when the
glider enters the radius around the TP that is set in the Logger Setup menu (see 5.1). Then the Colibri
displays the distance to the TP in 100 metre increments. This is very useful for competition as you
approach the turnpoint and often loose sight of it under the nose of the aircraft.
Once you have rounded a turnpoint the next turnpoint can be selected by simply using the vertical
arrows. After a short press of the UP or DOWN arrow a new turnpoint, which follows the old one
alphabetically, will be displayed. For approximately 1 second the turnpoint designation is shown in 8-
character form to confirm your selection. The internal database has a capacity for up to 600 turnpoints.
To make your TP selection quicker there are special algorithms which allow you to jump over TP’s. After
the ‘UP’ or ‘DOWN’ arrow is pressed and held down, the Colibri jumps through the TP database in larger
increments. Once the required TP is reached release the key and that TP will automatically be entered
for navigation purposes and the display will update bearing, track, TP name and distance to go.
Pressing the ESCAPE key in this screen will cause the four-letter TP designator to be replaced by a
display of the aircraft’s ground speed. Press the ESCAPE button again and the wind calculation
procedure is started. Wind speed and direction will be displayed as follows.
0980
25kph
The method of wind calculation is based on ground speed changes caused by wind effects during
circling (thermalling). To calculate the wind reading the Colibri requires two circles of the aircraft
(constant speed and no pilot induced change of position).
Pressing ENTER from any of the pages in the NAVIGATION menu will select the Turnpoint menu.
Which allows editing of turnpoint data and also task editing. The following screen will appear:

MENU
After using the ‘DOWN’ arrow, four sub menus will appear. Using the UP arrow reverses the order of
menu display.

the data as required or you can cycle alphabetically using the UP or DOWN keys by entering just the first
letter of the TP.
4.3 DELETING TURNPOINT
Select the TP and confirm the delete procedure with ‘Y’.
4.4 EDITING A TASK
The Colibri logger has enough memory to store 100 Tasks. One of these Tasks could be selected and
declared as an FAI Task (see SETUP LOGGER). This task has no relation or effect on the
NAVIGATION screen. Navigation data is selected using the turning points from the NAVIGATION menu
(screen). Selection of turnpoints during a flight is not automatic. The pilot must select the required TP for
navigation purposes from the Navigation screen. Finally, it is much easier to edit an existing task than to
create a new task when using the Colibri’s keypad. Tasks can be easily programmed using a PC.
After pressing the Enter key two different screens could appear, depending upon whether there are any
programmed tasks in the logger’s library or not.
TSK93 or for a pre-programmed task. TSK01
NOT PROG 4pt 155km
With programmed tasks, the display reads the task number, the number of turnpoints in the task, and the
distance of the task. Pressing ENTER from the EDIT TASK menu will bring up a programmed task. The
UP or DOWN arrows will cycle numerically through the task library. When you have reached the task
required, press ENTER. This brings up the first TP, number 0. Use the UP or DOWN arrows to cycle
through the task, when you have reached the TP you want to edit press ENTER, you will then be given
three options;
INSERT TPOINT DELETE TPOINT SELECT TPOINT.
If you select the INSERT TPOINT or SELECT TPOINT option, the turnpoint database comes up and the
required turnpoint can be selected from the Colibri’s TP database as mentioned previously. DELETE
TPOINT obviously removes that turnpoint from the task. To program a task that is not programmed in
memory( ie.‘NOT PROG’ is displayed), use the following procedure.
TSK 99 ENTER 0:NOTPRG ENTER
NOT PROG ------ -------km
TP NAME: select TP NAME: ENTER
**** AACHEN-D
0:AACHEN
---- ------km
The first turnpoint is called TPOINT 0, and it is actually the start point, this is selected. For the next TP
press the DOWN arrow once and ENTER. This brings up the TP database. The next TP is selected by
using the UP or DOWN keys, press ENTER to make your selection.
1:AJDOV
131 782km

Page: 8
The same procedure is used for all turnpoints and the finish point is the last TP. The whole ‘task edit’
procedure is completed by pressing the ‘ESCAPE’ key. Tasks can be prepared and edited on a PC and
transferred to the Colibri via its PC link cable. This procedure is much easier and quicker than using the
Colibri’s keypad.
Tasks can be edited in-flight if required for competitions (eg POST tasks, etc). However, please
familiarise yourself with task editing outside of the glider. It does take a little practice and when flying you
must keep a good look outside the cockpit for other aircraft! Note, the Colibri will not ‘beep’ when
rounding a turnpoint (ie when the glider enters the cylinder or photo sector) if a task has not been
declared. Of course the turnpoint rounded must correspond to the declared task. You can fly a task
without declaring it. Flight recording will still occur and subsequent flight analysis on a PC is available.
However, the rounding of a turnpoint will have to be determined by the pilot (no audible confirmation will
be given ie. ‘beep’).
4.5 EVENT BUTTON
This special key has two functions during the flight. A quick press will activate the event function which
changes the sampling rate interval briefly as defined in the Logger Setup menu. After a longer press of
the event button the following will appear on the display:
TP-QUICK
AP: 19:43
‘AP’ stands for actual position, and means your current position is stored as a turnpoint with the following
name ‘AP:19:43’. 19:43 is the time you marked the position, which allows you to distinguish several
EVENT marked positions from one another in the TP database. The names of these ‘AP’ turnpoints can
be changed using the edit function if required. This feature can be used to mark thermals, an outlanded
glider (hopefully as you fly over it!) etc. As the marked position is stored in the turnpoint database, you
can select one of the marked points in the NAVIGATION screen and fly to it later if required.
5.0 SETUP MENU
All the important logger parameters are defined in this menu.
SETUP
MENU
Using the vertical arrows the following sub menus can be selected.
LOGGER TIME UNITS NMEA COM PASSWORD
SETUP ZONE SETUP OUTPUT SPEED
5.1 LOGGER SETUP
All important logger parameters are defined in this menu. After pressing ENTER the following settings
can be altered.
NORMAL: After pressing ‘ENTER’ the cursor is activated, the recording (logging) interval is set .
12s Shorter recording intervals reduce recording memory. This is shown in the GPS STATUS menu.
NEAR TP: This sets the recording (logging) interval which is used as the glider nears the Turnpoint.
2s

Page: 9
Inside this radius around the TP, the logging interval (as set above) is used. Radius can be from
NEAR RAD: 0.1 – 2 km. Also Colibri will beep when the aircraft flies inside this radius, hence TP confirmation
1.0km dimensions can be set by the user.
PEV INT: This setting defines the logging interval which is used after the EVENT key is pressed.
2s
PEV FIX: This determines the number of fixes stored after the EVENT key is pressed.
30.
For example: If PEV INT 2s, PEV FIX 30 is set, then after the EVENT key is pressed 30 fixes, 2-
seconds apart will be recorded.
K Record this setting is not active on this model.
5.1.a DECLARED TASK
This a very important setting. The task which will be flown must be declared before the flight. A flight
without the proper declaration can not be evaluated as a badge or record flight. However full flight
recording and analysis functions (via a PC) are still available after the flight even if a task is not declared.
After ENTER is pressed from the DECLARED TASK menu, the following submenus are available.
COPY DELETE or EDIT
TASK TASK TASK
Selecting the COPY TASK option allows you to select from one of the 100 pre-programmed tasks in the
Colibri’s database. DELETE TASK clears the previously declared task, and the EDIT TASK option is
used to change a pre-programmed task (ie add or delete a TP) or to set up a completely new task.
An FAI task has the following structure:
TAKE OFF
START
TURNING POINTS
FINISH
LANDING
Example: The declaration of a completely new task using the EDIT TASK function.
After selecting the DECLARED TASK menu and ENTER, select EDIT TASK and press ENTER.
T:NOTPRG after Enter SELECT and Enter TP NAME:
TAKE OFF TPOINT *****
Selection of a turnpoint is done by replacing the stars with the letters or numbers corresponding to that
TP. After the Take-Off point is selected continue the procedure using the INSERT option to define the
Start Point. The same procedure is used for all the turnpoints of the task. Landing Point is automatically
set to the Take-Off point and the last turnpoint before landing is the Finish (F) Point. To change the
landing point to another turnpoint use the selection options. By using the UP and DOWN arrows the pilot
is able to check his task before leaving the declaration process.

Page: 10
IMPORTANT - The declaration procedure is completed by pressing the ESCAPE key.
The COPY TASK procedure copies one of the tasks from the database (see 4.4). The required task is
selected using the arrow keys. When using this method the take off and start positions are always the
same points, as are the landing and finish points. After the task is copied a normal edit procedure can be
used to modify it if required. All this data can be transferred to the Colibri before flight via a PC running
the LXFAI program.
5.1.b TPOINT ZONE
This allows the pilot to select the appropriate turnpoint ‘rounding’ confirmation method required. Two
options are available; FAI photo-sector or cylinder.With the cylinder confirmation option, the radius
set in LOGGER SETUP-NEAR RAD(see section 5.1) defines the cylinder’s dimensions. An acoustic
signal (beep) will be activated when the aircraft enters this cylinder to alert the pilot. This is very useful
for competition, which currently allows cylinder turnpoint confirmation. The pilot simply flies directly to the
TP, when the alarm sounds (Colibri beeps), entry into the cylinder and hence rounding of the TP is
confirmed. The pilot then makes track for the next TP on task. By selecting the photo-sector option, the
acoustic signal will be activated when the aircraft enters the photo sector. Competition pilots must
determine, from the organisers, what turnpoint confirmation method is to be used for the particular
competition entered and ensure the Colibri is set up appropriately.
5.1.c TPOINT BEEP
To adjust the acoustic signal of the turnpoint confirmation BEEP, two parameters, the INTERVAL (time
between beeps) and PERIOD (duration) can be adjusted by the pilot. After adjusting the parameters
mentioned, selecting the BEEP TEST option will activate the alarm enabling you to check the settings.
5.1.d I-RECORD DATA
Additional data recording options are available with the Colibri if required. This menu extends logging
data if the yes ‘Y’ option is selected. These settings are not essential for flight recording but if used they
will reduce the memory capacity available for flight recording. The memory available for flight recording
will be displayed on the GPS STATUS menu screen after selecting the options required. See section 3.

5.1.e J-RECORD
The ‘J-Record’ has the same optional settings as the ‘I-Record’ and again are non-essential. It will
reduce the memory capacity available if used.
5.1.f FLIGHT INFO
Information about the pilot, glider and observer are entered using this menu. This can be done on a PC.
PILOT: - Pilot’s name
GLIDER: - aircraft type, eg Nimbus 3
REG.NUM: - Registration number of the aircraft
CMP.NUM: - Competition number
CMP.CLS: - Competition class
OBSERVER: - Name of official observer

Page: 11
5.2 TIME ZONE
The Universal Time (Greenwich Mean Time-GMT) to local time offset is entered in this menu. For
Eastern Standard Time in Australia the offset is +10hrs (+11hrs during daylight saving).
5.3 UNITS SETUP
The preferred units of distance, height and speed are selected in this menu.
5.4 NMEA OUTPUT
The Colibri can transmit GPS data to a final glide/flight computer or palmtop computer via the NMEA
0183 protocol. Obviously the flight computer must have the facility to accept GPS input. The NMEA
output data strings transmitted by the Colibri are selected in this menu. The sentences you select for
transmission will depend upon the requirements of your flight computer, and you are referred to your
flight computer’s manual for guidance. The wiring details for NMEA output are contained at the end of
this manual. Pay particular attention to the wiring details when making this connection yourself. You will
have to connect the appropriate plug for the flight computer to the Colibri’s power cable. Your dealer can
help you with this. If you do not connect the Colibri to a flight computer then you can ignore this menu.
5.5 COMM SPEED
The baud rate or communication speed with which the Colibri sends and receives data is set in this
menu. For reliable and fast transfer of data to and from your PC set this speed to 19200. Your final
glide/flight computer may require a different communication speed to this. You will need to set the
appropriate COMM SPEED prior to flight. For example the Cambridge LNAV requires a 4800 baud rate.
5.6 PASSWORD
A password security system can be set up on the Colibri if desired, although for general use it is not
recommended. Setting the password to 99999 in this menu clears all the flight recorded data in the
Colibri’s memory.
6.0 VIEW LOGGER
All flights stored in the instrument can be evaluated using this menu. Downloading flight data to a PC will
not delete the flight from memory. If the memory is full, the oldest flights will be lost, that means an
automatic overwrite procedure is used. Hence you will never run out of memory for the flight in progress.
Only entering 99999 in the Password menu will delete all flights stored in the Colibri’s memory. To
evaluate a particular flight in the memory, select the VIEW LOGGER menu: Note, this menu will not be
accessible if there are no flights stored in the logger.
VIEW

declared. If the flight was not declared then comprehensive flight statistics can only be viewed after
downloading the flight data to a PC and entering the actual task flown using the PC’s turnpoint database.
For a non-declared flight only the take-off time, landing time, flight duration, and date of the flight will be
displayed on the Colibri’s screen.
7. PRE-FLIGHT PROCEDURES
The Colibri is ready to be used as a flight recorder as soon as the GPS OK message appears. For flight
data logging only, it is not necessary to declare a task. With flights for badges and records it is essential
to declare the task, and enter the pilot information etc. in the SETUP menu before take off.
The procedure is as follows:
1. Define cylinder or photo sector for turnpoint rounding confirmation.
2. Declare the task on the ground
3. Switch the Colibri ON approx. 5 minutes before take off (this will not reduce the memory).
4. After landing DO NOT switch off the instrument immediately. Wait until the message ‘security
check’ appears, or LOG:STOP appears in the GPS STATUS menu as shown below. Now you
can switch off the unit.
LOG:STOP
Mem.89.7h
Flight recording (logging) automatically starts when the aircraft’s ground speed exceeds
20kph and logging will automatically cease approximately 40 seconds after the glider has
stopped moving (ie landed).

Page: 14
8. PC CONNECTION
The Colibri communicates with a PC via the RS232 port and the cable supplied. Data can then be
transferred between the PC and the Colibri. The following functions are available when the unit is linked
to a PC.
Read Logger-This allows downloading of flight details and flight (logging) data stored in the Colibri. The
list of flights stored in the logger appears and a flight is selected for download using the PC’s cursor
keys.
Setup Logger- all logger parameters can be selected/entered via the PC’s keyboard and uploaded to
the Colibri.
Read Flight Info- Data regarding the Pilot etc is read from the Colibri.
Write Flight Info- Data regarding the Pilot, Official Observer, Glider etc is entered on the PC and written
to the Colibri.
Read TP and TSK- The turnpoints and tasks stored in the Colibri are downloaded to the PC for editing if
required.
Write TP and TSK – The turnpoint and task data stored or edited on the PC is transferred to the Colibri.
8.1 PROCEDURE FOR PC CONNECTION:
Install the LXFAI program onto your PC using the supplied floppy disk. Run the LXFAI program. Connect
the PC and Colibri using the special cable supplied. Press ‘T’ on the PC’s keyboard, the Colibri will
‘beep’ while it is communicating with the PC and display CONNECT. The PC’s screen will display a
number of options;
Read logger COLIBRI
Setup logger
Read flight info 19200 bps
Write flight info CONNECT
Read TP and TSK
Write TP and TSK
For instance after selecting write flight info, the data regarding the pilot and glider will be transferred
from the PC into the Colibri. The ‘Read’ command will transfer data from the Colibri to the PC. If you are
having trouble establishing connection with your PC, make sure that the Colibri’s COMM SPEED is set
to 19200 in the appropriate menu, see section 5.5 of the manual. This is particularly important if you
have the Colibri connected to a final glide/flight computer during flight. For example, the Cambridge
LNAV requires a 4800 baud rate from the data logger. This baud rate is selected on the Colibri (as per
section 5.5) when installing the Colibri in the glider before flight. Note, you will need to change the
COMM SPEED back to 19200 when connecting the unit to a PC after the flight.
If you do not connect the Colibri to a final glide/flight computer, then leave the COMM SPEED set on
19200.

Page: 15
9.0 WIRING DETAILS and POWER SUPPLY CONNECTION
The Colibri is immediately ‘ON’ when power is applied to the connector (there is no separate ‘ON’ switch
as such). Each unit is supplied with two cables;
1. Power supply cable for installation in the aircraft.
2. PC cable with power supply and RS232 plug for connection to your personal computer.
The Power Supply Cable in addition to supplying power to the unit also has;
a. Output for an LED to enable GPS monitoring if the Colibri is mounted out of view of the pilot.
b. NMEA output for connection to final glide/flight computers, palmtop computers etc.
The user can make both connections, however some electronics experience is required, particularly
soldering skills. It is recommended that you consult your dealer for advice if you do not feel competent to
make these connections. The colour coding of the flat, black 6-wire cable used for connection to the
Colibri is shown below. Note this applies to the thin wires inside the black telephone type cable. For
convention, that is, so that red and black wires are used for connection to a battery or power supply,
thick red and black wires are soldered onto the appropriate inner wires of the telephone type cable. Blue
for the red(+) and yellow/white for the black (-) respectively. This is important if you wish to splice open
the cable to effect NMEA output connection to a flight computer or use the LED output monitoring option.
If not, just connect the thick red wire to the red positive ’+’ terminal of the battery and the black wire to
the black negative ‘-‘ terminal of the battery. Insert the telephone type connector into the Colibri and the
unit is now switched ON! It is recommended that a 1-amp slow blow fuse is connected between the
battery and the power cable.

10.0 ADDITIONAL INFORMATION
10.1 A Low Battery warning is displayed when the battery voltage drops to 10.0V regardless of which
screen you are using at the time. Press the ENTER button to resume control of the Colibri’s functions.
Logging does not stop during this time. The unit will continue to operate down the 9.0V. When the
battery is exhausted the Colibri will BEEP continuously, and logging will cease. The battery voltage is
continuously displayed on a page in the GPS STATUS menu if you wish to check the current state of
your battery’s voltage.

11. IMPORTANT NOTES
1. It is recommended that you familiarise yourself with the Colibri’s operation by connecting
the unit to the PC cable and mains power pack. This will enable you to practice the
operation of the unit. If you wish to obtain GPS fixes ensure the aerial is connected. Note;
no harm will come to the unit if power is applied without the aerial connected. Re-read
the manual with the Colibri in hand and its operation will become clear and simple.
2. The Colibri uses an internal lithium battery to retain the memory of stored data. After
several years this battery will need to be replaced. Return the unit to the place of
purchase to effect replacement. This is not covered under warranty.
3. Do not disassemble the Colibri, that is undo the case screws. This will destroy the
unit’s security seal and the logger will no longer function. There are no user serviceable
components inside the Colibri. If you disassemble the unit it will have to be returned to
the factory for reassembly. This will also void the warranty.
4. It is recommended you seek assistance with the electrical connections for the Colibri if
you are not experienced with electronic work. Alternatively contact your local agent to
seek assistance with your installation.
5. If you intend to connect the Colibri to a flight computer the required NMEA output
sentences (as per the flight computer’s manual) are selected in the SETUP menu.
6. Turnpoints are best entered into a PC using the LXFAI program (decimal minute format).
Once all the TP’s are entered into your PC you can download them to the Colibri. Contact
your dealer he may be able to supply the turnpoints you require on floppy disk for input
into your PC or install them prior to shipping your order.
7. The Colibri’s pressure transducer is calibrated with reference to the 1013Hpa
International Standard Atmosphere (ISA) mean sea level (MSL) pressure datum.
