15 Operating Instructions FLYTEC 4005
Operating philosophy
The philosophy behind all Flytec instruments is to keep everything as simple as possible. This
is why each key has only one function, i.e. a function can be displayed and switched on or off
with each key. In order to alter a function, you press and hold down the r elevant function key.
The setting to be changed will then flash and can be altered by pressing and .
The instrument has three operating modes: normal operating mode, setting mode and configuration mode.
Run mode (normal operating mode)
The instrument is in run mode when used in normal operation. In run mode, the instrument will
display your altitude, ascent and the time continuously.
Setting mode (for adjustments)
In setting mode, the most important value can be changed for each display. For example, the
altitude can be set by using the setting mode for altimeter 1.
Enter setting mode for a particular display (e.g. for altimeter 1), by pressing the relevant function key (e.g. ) and holding it down for about 4 seconds. As soon as you are in setting
mode, the SET indicator will appear in the INDICATOR display . The value to be changed begins
to flash.
In order to return to run mode, press the relevant function key briefly (e.g. )
If no change is made in setting mode for 15 seconds, the instrument returns to run mode.
Option mode (configuration mode)
Option mode allows you to configure the instrument to your requirements and preferences. In
option mode, you can set the parameters for the relevant display or function at various levels.
For example, these can be units or special functions. A precise description of the various settings in option mode is given in the descriptions of the individual functions.
You can enter option mode (in the setting mode of a function) by simultaneously pressing the two keys marked “Option” in yellow (Fig. 1). If the
instrument is in option mode, this is confirmed by the OPTION indicator in
the INDICATOR display.
In OPTION mode you can change several parameters. By briefly pressing
the relevant function key (e.g. ) you skip from one level to the next. In
each level you can change one parameter of the relevant function. The level
number will appear each time in the digital vario display.
If no change is made for 15 seconds in option mode, the instrument returns
to run mode.
In order to return to run mode manually, press the two option keys simultaneously again (Fig. 1).

Commissioning
Switch on the instrument with the On/Off switch. On being switched on, the instrument goes
through a self-test routine and then enters run mode.
When switched on, the instrument settings correspond to those valid when the instrument was
last switched off.
When first switched on, the instrument displays the approximate charging status of the batteries in the vario bar display. If the display shows approximately 50% of the maximum display
in the green sector, the batteries are still half full. If the display is in the red sector, the batteries must be changed. If the batteries are low on charge during a flight, PO will light up briefly
in the digital vario display and, at the same time, the charging status of the batteries is shown
in the bar display.
The battery life of the instrument using alkaline batteries is 160 hours. Rechargeable batteries
can also be used. However, operating time is substantially shorter with these (total operating
time is approximately 40 - 50 hours).
Alkaline batteries can also be recharged several times using the appropriate charging unit (no
fast chargers!).
The altimeter
General remarks
How does an altimeter work?
An altimeter is really a barometer because it does not measure altitude directly but pressure.
The altitude is then calculated from the pressure. For the purpose of calculating absolute altitude (according to the international formula for altitude), the pressure at sea-level is assumed
as being zero-point pressure.
Why does pressure change with altitude? The air pressure at a point on Earth is produced by
the weight of the atmospheric air above it. This is why air pressure decreases with altitude there is less air above your head! At 500 meters above sea-level, a pressure change of 1 mbar
corresponds to a difference in altitude of about 8 meters.
In practice, however, it is not quite that simple as other factors also have an influence on air
pressure. Pressure also depends on temperature and, of course, weather. On a stable day,
there can be air pressure fluctuations of 1 mbar caused by temperatures and this corresponds
to a difference in altitude of ± 10 meters. Depending on the weather, air pressure at sea-level
(QNH) can be between 950 mbar and 1050 mbar. In order to eliminate this weather effect, an
altimeter needs continual recalibration. This means that the altimeter must be set at a known
altitude to display that same altitude.
English
When the weather changes fast (e.g. cold fronts), air pressure can change in the course of a
day by up to 5 mbar. This repr esents a change in altitude of 40 meters!
Another method of calibrating an altimeter is by entering the current QNH. What is the QNH?
In flying circles, a general zero point is needed to enable all aircraft at the same altitude to also
have the same altitude on their altimeters. This joint basis is called the QNH. The QNH is the
current air pressure in hPa (1 hPa = 1 mbar) calculated at sea-level. It is redetermined several
times daily and can be obtained in the flying weather report or from airfields by radio.
Altimeter 1 (AL T 1)
Altimeter 1 displays absolute altitude, i.e. the altitude above sea-level.
Function key is used to change from the displays for altimeter 1, altimeter 2 and the stop-
watch. Pressing and holding down this key will make the instrument go into setting mode.
Altimeter 1 setting mode
As mentioned above, the absolute altitude can be
set in setting mode. The altitude and the QNH flash
on 2 lines. Using the setting keys
and , you can set the altitude and the QNH
simultaneously. If you do not know what altitude
you are currently at, you can set the altitude using
the QNH but this method is not as precise as direct
altitude setting. The QNH has a resolution of 1
mbar which corresponds to an altitude resolution
of approximately 8 meters. The altitude, however,
can be set directly to an accuracy of 1 meter.
Pressing the setting keys and simultaneously will take you from setting mode to option
mode.
Altimeter 1 option mode
In option mode, you can set the unit for ALT 1
(meters or feet) at the first level and, at the second
level, you can set the unit for the QNH (hPa or in
Hg). The indicator for the relevant unit set flashes
in the display.
The pressure sensor can be corrected at the third
level (± 50 hPa).
If you find that the QNH value displayed at a known altitude deviates seriously from the QNH
value of a weather station in your area, you can correct this deviation by entering the deviation (with a different prefix). I.e. if the QNH displayed by your instrument is 20 hPa too high, enter
-20 to correct this deviation.
This deviation is caused by the aging of the pressure sensor and stabilizes after 2 - 3 years.

N. B.: Incorrect manipulation of the correction value of the pressure sensor will result in false
altitude readings! Never alter the basic settings of the altimeter unless you have good reason
to do so (in your own interest)!
In option mode, the indicators OPTION and ALT 1 appear and the relevant number of the module is shown at the top of the display. The unit to be adjusted will flash.
Altimeter 2 (AL T 2)
Altimeter 2 can either be used as an absolute alti-
meter or as a relative altimeter.
When used as an absolute altimeter, it functions in
precisely the same way as altimeter 1. Altimeter 2
can now, for example, display the altitude in feet
and altimeter 1 the altitude in meters.
The relative altimeter displays the current altitude
with reference to a point. This reference point can
be set at zero in run mode at any time by using the
key or set at any altitude in setting mode. The
relative altimeter can thus be used to measure the
higher altitude of the take-off area. Pressing the
key at the take-off area will zero AL T 2 for this
purpose.
Altimeter 2 setting mode
The altitude can be set in setting mode in precisely the same way as with altimeter 1.
If altimeter 2 is selected as the absolute altimeter,
it is coupled to altimeter 1. Any change in the display for altimeter 1 is reflected by a corresponding
change in the display for altimeter 2 and viceversa.
Altimeter 2 option mode
In option mode, you can select the unit (meters or feet) at the first level as with altimeter 1. The
unit selected flashes in the display. Y ou can toggle between units by pr essing either the key
or the key.
Press key to enter the second level of option mode. At this level, you select the operating
mode of altimeter 2. If this is set at absolute altimete, the two indicators ALT 1 and ALT 2 will
flash in the display. If set at relative altimeter, only the indicator ALT 2 will flash.
You retur n from option mode to run mode by waiting 15 seconds or again pressing the two
keys marked “OPTION” simultaneously.

Vario
Vario sound levels
Two sound levels can be set or the sound system switched of f completely by repeatedly pressing the key. While the key is pressed, a tone will sound at the desired level.
Analog vario bar display
The vario bar display has a range of ± 8 m/s in two scale passes. The scale unit always corresponds to 0.2 m/s. Up to 4 m/s , the bar display fills. If it displays more than 4 m/s (ascent),
the ascent is displayed inverted, i.e. the display is full at 4 m/s and empties from below when
ascent increases.
E.g.:
The sensitivity of the bar display corresponds to the basic attenuation of the vario (‡ setting
mode of the vario). It therefore always displays current ascent.
Digital vario display (Integrator)
The digital vario displays the attenuated climb rate for the last X seconds in second rate. The
time X, via which ascent is attenuated (integration time), can be changed at the first level of
option mode. These values appear flashing in the digital vario display.
You can enter the vario’s setting mode by pressing the key for a long time (approximately 4 seconds).
Vario setting mode
The basic attenuation of the vario can be altered in setting mode. The basic attenuation of the
vario is effective on all vario functions; it can be set to 0.5 sec, 1 sec or 1.5 sec.
N.B.: The fastest vario is not always the best vario. In very rough and severe conditions, it is
advisable to attenuate the vario more. Turbulences ar e then filtered out by the attenuation and
not displayed.
You can enter option mode by simultaneously pr essing the two option keys.

Vario option mode
The integration time of the digital vario can be
altered at the first level of option mode. The
values are in 5-second steps between 5 and 35
seconds and appear flashing in the digital vario
display. At setting 1, the digital vario is displayed
without averaging and then runs parallel to the
bar display. The values can be altered with the
and the keys.
The audio response point can be adjusted at the
second level. The audio response point can be
adjusted from +2 cm/s to +40 cm/s. The current
response point appears in the bar display and
represents one tenth of the value displayed. E.g.:
a display of 2 m/s corresponds to an audio response point of 20 cm/s.
The digital vario unit can be selected at the third
level: m/s or feet/min x 100. The current setting
flashes in the digital vario display. Y ou can switch
between the two units with the key.
Descent tone/Descent alarm
The descent tone is a continuous tone dependent on descent which sounds as soon as descent is greater than the response point. The descent tone can be set or switched off with the
key. When the descent tone is active, the SINK indicator is displayed. When the descent
tone is first switched on, a mark appears in the bar display indicating the response point set.
Descent alarm setting mode
The response point of the descent alarm is set in
the bar display using the keys. The response point
can be set over the entire range of the display and
also remains stored in memory after the instrument
has been switched off.

Speedometer
General remarks
A speed sensor (speedometer) can be purchased as an accessory. The speed sensors in the
3000 series can also be used with instruments in the 4000 series.
The accuracy of a vane wheel sensor is highly dependent on its point of attachment.
Additionally, the individual probes have an accuracy of approximately ±2.5% (industrial standard) resulting from manufacturing operations and it is possible for two probes not to display
exactly the same speed. These deviations can be largely corrected by the instrument. ( option mode of the speedometer).
Display
If a vane wheel sensor is connected to your instrument, speed (in kph, mph or knots) relative
to the air can be shown in the lower display by pressing the key.
When a stall alarm is switched on, a warning tone sounds when speed falls below a certain
absolute speed. No stall alarm will sound at speeds that are below 10 kph. If the threshold is
set at 10 kph (or 5 mph), the stall alarm is switched off.
The current time can be shown every 30 sec in the SPEED display ( option mode of the speedometer).
Correction
If a probe always displays too much or too little, this
deviation can be corrected at the third level of option mode.
Speedometer setting mode
The response threshold of the stall alarm can be altered. If the threshold is set at 10 kph (or 5 mph), the
stall alarm is switched off.
Option mode of the speedometer
At the first level, you have a choice of whether the
time should be displayed automatically every 30
seconds when the speed display is switched on.
At the second level, the desired unit of the speed display is set. You can choose between kilometers per
hour (kph), miles per hour (mph) and knots (kts) by
using the key and the key.
At the third level, you can also make adjustments to
the correction of the speedometer. The correction
value is given in percent using the key and the key.
If the speed display is uncorrected, the display will
show 100 (%). If the display still shows a 4% excessively high value (e.g. 50 kph instead of 48 kph), the
display is corrected by setting 96 (%). This means
that the display will now always show 96% of the original speed.
