2General
The instrument consists of two units, the main unit (80 mm) and LCD Vario indicator (57 mm). Additional LCD Vario
indicators can be added.
The fast calculation processes and graphic displays are achieved by using modern microcontroller technology. The
sensors are modern, highly precise, temperature compensated pressure sensors for altitude and speed to eliminate errors
Vario functions
•Vario, Netto, Relative and Average
•Speed command
•Final glide calculator
•TE compensation (TE-tube or electronic)
Navigation functions:
•Jeppesen airport and database or Europe (up to 5000 airports)
•600 turnpoints
•100 tasks
•Statistics
•Near airport function
The manual is written for all instruments having program version 9.x and also for all the instruments being hardware
upgraded from 6.x to 8.x or 9.x
What does LX5000FAI mean?
LX5000 FAI has abuilt in approved IGC logger and therefore one additional pressure sensor for altitude. Special
software on the device is responsible for stored data integrity, which means no manipulation is possible.

2.2 Rotary switches and keys (buttons)
The following control elements are mounted on the main unit
•Four rotary switches (selectors)
•Five keys (push buttons)
The LCD-Vario is designed as a slave unit, which means it has no control switches and keys.
2.2.1 On/Start key
A short press on ON/Start key will switch the instrument ON. To switch the instrument off hold ESC/OFF key for a few
seconds and the instrument will be switched off. To switch the instrument off during the flight it needs a confirmation
from the pilot, so the LX5000 cannot be switched off by mistake.
IMPORTANT!
After having a short power brake during flight and the instrument will be off for a few seconds, it will not produce two
flights.
During flight the key is used to start the task, to see more characters of airport names and, in the edit menu, to go one
step back if e.g. an error has been made (see paragraph APT).
2.2.2 Mode selector (rotary switch)
The mode selector is used to change modes of operation. This switch has the highest priority in the system. Whenever
it is activated a mode changeover will happen.

2.2.3 UP/Down Selector (rotary switch)
This rotary switch has a lower priority than the mode selector switch and is active all the time in the selected mode. It is
mainly used for selecting sub menus during navigation and to scroll in the edit menu.
2.2.4 ENTER key
The main function of this key is confirmation and to start edit procedures.
2.2.5 ESC/OFF key
This is a multifunctional key, which has two main functions.
•After ESC is pressed a jump to the menu of the next higher level will follow
•During the input of letters and numbers (blinking cursor) ESC confirms the whole row (not necessary to press
ENTER few times)
2.2.6 EVENT key
Activates the Event function (see Chapter 3.1.1.2, LOGGER)
2.2.7 MC/ BAL key
Provides Mc Cready (MC) and ballast setting. The ballast setting is possible after a double click. The value is changed
with the UP/DOWN-selector. (In the elder series of LX5000 there are two separat rotary switches for MC and ballast)
2.2.8 ZOOM (rotary switch)
This is a multifunctional rotary switch. Its main function is to change the zoom level in the graphic mode. Additionally
the zoom switch is used as follows:
•To select turnpoints (only in TP main page)
•After a mistake during editing it is possible to go back some stages by rotating this knob (only when the cursor is
blinking = editing is active)

3Operation modes
The LX5000 has 7 modes or main menus. All of them are selected directly by rotating the mode selector. The diagram
shows the menu (mode) structure of LX5000.
⇐MODE⇒
GPS NEAR APT TP TSK STATISTICS SETUP
⇓⇓⇓⇓⇓
⇓⇓⇓⇓⇓
Navigation menus (APT, TP,TSK) have sub menus, which are selected using up/down selector.
GPS GPS status, no inputs
NEAR Near airport, choose one airport, no further inputs available
APT Navigation and selection of airports
TP Navigation, selection and edit of turnpoints
TSK Navigation, selection and edit of task
STAT Flight statistic and logbook
SETUP is organized in two levels. The first level (no password required) is accessible for everybody. For the second
level, the pilot has to use the password. The password is not a top secret; it is the same for all instruments and published
96990
After installation of the LX5000, it is necessary to activate the password and adjust the settings of the instrument and the
desired units.
3.1 SETUP
3.1.1 SETUP before password
Changes can be made at any time. This first level contains no system settings at all.
The up/down selector will select the different menus.

3.1.1.1 QNH RES (QNH and safety altitude)
After switching on, the pilot has an opportunity to input the actual QNH, taken from meteorological service. Using this
feature it is possible to offset the altitude datum, which could have been changed due to pressure changes during the
flight. Without input of initial QNH before the flight, this function is not active.
Any change of the QNH influences the measured altitude. A wrong setting can therefore cause an unprecise final glide.
Procedure:
•Use the up/down selector to choose the item (QNH, ALT.R. MG.VAR. or BUGS)
•Press ENTER
•Use up/down and ENTER for input
•Close the procedure with ESC
Some GPS receivers don’t deliver magnetic variation (MG.V.). In that case the input of a typical value of variation for
the area flown in is obligatory, especially if the magnetic compass is used for wind calculation, or magnetic track is used
in navigation. Having a receiver, delivering variation, no input is possible and necessary (AUTO message will appear)
Example above: safety altitude 000m, QNH offset not possible.
“BUGS” is polar degradation because of “buggy” wings. The input is in glide ratio degradation percentage.
(5%, means glide ratio degradation is 5%)
3.1.1.2 LOGGER
As mentioned before, the flight recorder (logger) is approved by the IGC commission. ( Governed by the FAI.)
After “enter” the LOGGER will follow.
Under “FLIGHT INFO” all important data, such as pilot (name), glider type, call sign, competition sign and comp.
class are stored. Also the name of the official observer can be entered. After pressing ENTER on FLIGHT INFO all
these parameters are accessible. Naturally all these settings are available with a PC and the Lxe-program or via Colibri
or LX20 (see Chapter 4). The settings are performed with ENTER UP/DOWN and ESC.
Example:
to
Please note, there is an important change compared to earlier versions: With the version 9.0 the glider
type, set under Setup ->Password -> Polar, see 3.1.2.10, is automatically written into the IGC file-header.
If one likes to fly with a polar other than that of the used glider, one should write the parameters of that polar
into the user polar and should term it with the name of the used glider (important at decentralized competitions,
Online-Contest, Barron-Hilton-Cup...)

LX5000 March 2002

Before leaving the FLIGHT INFO menu one can save the pilot´s data in a pilot list.
Confirming with Y(es) stores the pilot into the pilot list, what means this pilot can be chosen during the start-up
procedure.
Important !
If the the pilot is not added to the list (ADD PILOT TO LIST N) one has the private pilot modus. In this case the
LX5000 offers no choice of pilots and after 30sec the SET ELEVATION procedure is started.
On the other hand, having added more than one pilot to the list, a pilot can be chosen out of the list during the boot
procedure (Choose with UP/DOWN and confirm with ENTER). This is called the Multi-Pilot Option. For details see
chapter 3.4.
LOGTIME is an important setting for sufficient flight recording.
TOTAL MEMORY is the capacity of memory and depends on the settings only. This number is not reduced after some
flights are stored. It changes only after new settings have been made in the setup. The total memory indicates how many
hours of flight can be flown without loosing the flight data because of overwriting. If the memory is full, the oldest
flights will be overwritten without warning.
B-RECORD: position, GPS altitude, pressure altitude, UTC and GPS status are recorded
Pilot sets record interval, the default value is 12 seconds.
K-RECORD: not active by default
NEAR TP INT.: being close to the turnpoint (inside NEAR RAD), the logging runs faster
NEAR TP RAD.: radius that defines NEAR
(I) RECORD
Using this record some more flight parameters can be logged. Setting Yactivates additional logging.
-FXA: current horizontal accuracy of GPS
-VXA: current vertical accuracy of GPS
-RPM: engine RPM
-GSP: groundspeed
-IAS: indicated airspeed
-TAS: TAS
-HDM: mg. heading
-TRM: magnetic track
-TRT: true track
-TEN: total energy
For motor gliders ENL: Y

LX5000 March 2002
page 9
-WDI: wind direction
-WVE. wind
-VAR: vario
-ENL: engine noise level (Must be Y when flying powered gliders)
Each activated setting will reduce the total memory capacity.
(J) RECORD
J record has the same settings as I record, but will build a separate file. Using this record reduces the total memory
significant.
EVENT
After pressing EVENT key, the logger will run a limited time faster as defined in LOGTIME. Activation of EVENT is
recorded as a special record in the IGC file. Some competition rules require using EVENT before departure.
Example: after EVENT, 30 additional fixes will be logged in 2-second interval.
3.1.1.3 INIT
The following parameters can be re-defined using this setting.
•VARIO FIL: damping of vario indicator from 0.5 up to 5, default setting is 1.0 (nominal seconds)
•VARIO INT: vario average time, 20 seconds default
•VARIO RNG: vario range
•TAB: audio dead zone during speed command flight
•ETA: Calculation of the estimated arrival time: GS based on the actual groundspeed, VAR based on
the averaged variometer value of the complete flight so far, Mc based on the actual Mc-
setting.
•AUTO SC: speed command change-over method
OFF: only with external switch
GPS: after climbing ( circling) is detected using GPS, an automatically change over will
happen
XXX: TAS in 5 km/h steps from 100 up to 160 km/h (knts, mph)
•WIND/COMPASS: compass is an optional device which can be connected to the LX5000 485 bus. The device
delivers magnetic track and one additional wind calculation method can be used. The method
needs a straight flight. The time for calculation is set using this menu (normal 15 seconds).
Longer time means a better wind calculation.
