Introduction

Flytec’s 4030 is a completely new development. The new instrument is now more compact,
lighter and more economical thanks to the use of the very latest technology .

The 4030 is an instrument which you can adjust to suit your requirements. For this reason, all
important data can be altered quickly and easily. You’re flying in the United States? No pro­blem: Altimeter 1 displays the altitude in feet and Altimeter 2 displays the meters to which you
are accustomed! This is just one example of what the 4030 has to offer.

With this new instrument, we have remained loyal to Flytec’ s operating philosophy - and also
improved it with the new option mode. Flytec’s new 4030 is an instrument that will give you
immense enjoyment.

Keyboard

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 relevant function key
for approximately 3 seconds. 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 INDICA TOR 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 prefer ences. 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 INDICA TOR 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 , pr ess the two option keys simulta­neously again (Fig. 1).

Using FlyChart 4.0 software on a PC, all settings in setting and option modes
as well as additional configurations can be conveniently set and transmitted
to the instrument via the PC interface.

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 char ging 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 pr oduced 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 corr esponds
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.

Flytec

Operating Instructions FL YTEC 4030 8

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 r epresents 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 (ALT 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.
Attention: While a flight is being r ecorded (REC

activated) the setting mode is blocked for Alti­tude 1. This altitude can only be readjusted after
the REC has been switched off. This is an FAI
requirement.

Altimeter 1 setting mode

As mentioned above, the absolute altitude
can be setin 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 inHg). 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 and target altitude (ALT 2)

Altimeter 2 can either be used as an absolute
altimeter 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 take­off area. Pressing the key at the take-off
area will zero ALT 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 vice-versa.

Altimeter 2 option mode

In OPTION mode, you can enter the target altitude at the first level using the key and
the key.
Use the key to enter the second level of OPTION mode. There, the GPS-supported func­tions of the instrument can be switched on or off.
The unit of the AL T 2 display (meters or feet) is determined at the thir d level. The currently
selected unit flashes in the display. Use the or the key to toggle between the units.

Press key to enter the fourth 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 r elative altimeter, only the indicator ALT 2 will flash.

You return from option mode to run mode by waiting 15 seconds or again pressing the two
keys marked “OPTION” simultaneously.
