1 Introduction
With it's innovative ideas and modern technology the ALPHAMFD offers a complete
system for flight and engine-management for ultralight/microlight pilots. Important
information for navigation and engine control are easily readable, presented on an
integrated Liquid Crystal Display.
The ALPHAMFD was carefully designed to be extremely reliable, safe and
maintenance free. A self-test on power-on, detection and warning of faulty senders
and the audio alarm through the Intercom make the ALPHAMFD an extremely
reliable and safe flight information system.
Using modern processors and a flash-memory, the software of the ALPHAMFD can
be updated any time and thus being updated to the latest software version without
hassle and cost. The ALPHAMFD is a sound long-term investment.
In order to avoid information overload of the pilot, only the most important information
like speed, vario, altitude, RPM, EGT, CHT or water/oil-temperature, flight time, realtime, fuel state and consumption, are permanently displayed. More information can be
called up by pressing only a few keys, e.g. flight log or engine hours, etc.
The innovative LC-display is easy to read in any light conditions, all read-outs are
designed following ergonomic rules.
Because of the logical and clearly structured menus, the ALPHAMFD is very easy to
operate. You basically only have to switch on the instrument and off you go. However
we strongly recommend you read the operation manual carefully to make the best out
of the many functions the ALPHAMFD offers.
We wish you many fantastic and safe flights with your new ALPHAMFD.
Note:
The operating instructions contain many important information which are necessary for
a safe operation of the ALPHA
ALPHAALPHA
ALPHAMFD. Please read the instructions carefully! If you do
not understand something, you must not use the ALPHA
ALPHAALPHA
ALPHAMFD. If you have questions,
please contact the nearest
BRÄUNIGER
Service Centre or
BRÄUNIGER
directly.
WARNING! This icon designates important safety information in the

2 Mounting and Connections
2.1 Warning
The ALPHA
ALPHAALPHA
ALPHAMFD is not certified by LBA/FAA/JAA as this is not required for Ultralights
in most countries. However, if such a certification will be required in the future, the
certification will be completed. The instrument is designed following the most state of
the art technologies and it is extensively tested following the procedures of LBA!
Although the ALPHA
ALPHAALPHA
ALPHAMFD is an electronic and very precise instrument, incorrect
values can be shown, mistakes in operation can be made and shown values can be
misinterpreted. By operating the ALPHA
ALPHAALPHA
ALPHAMFD, the user confirms that he knows about
these dangers and he is accepting responsibility for any possible risks.
In order to minimize these risks, the operating instructions MUST be read carefully. If
you have questions, please contact
BRÄUNIGER
or a
BRÄUNIGER
Service Centre.
2.2 Mounting into Cockpit
It is very easy to mount the ALPHAMFD in your cockpit. You only need a little skill,
no special tools are required.
Dimensions of ALPHAMFD:
Front 220 x 145 mm
Cockpit Cut-out 137 x 194 mm
Drillings 207 x 87 mm, 32 mm from

WARNING:
The following points must be carefully observed:
• Protect the unit from too high or too low temperatures. The unit works reliably in
a temperature range of -15°C to 50° Ceslsius.
• Protect the unit from excessive shock or vibrations. It might be necessary to
mount the unit with suitable shock absorbing materials.
• Protect the unit from dirt and moisture and all kinds of oils and gasoline.
• The display must be easy to read, protect the unit from glare and ensure a good
field of view.
• Mount instrument as far away from radio / transponder antennae as possible.
All points must be observed for longevity and reliability!
2.3 Electrical Connections
If you have never before installed electrical instruments and you are not exactly sure
what to do, please ask someone who has experience to help you with the installation.
When working with senders, please handle carefully, as they are sensitive electronic
parts.
Only use high-quality cables (highly flexible, stranded and shielded) and connectors.
Check that your cables run untangled and clean. Disconnect the aircraft battery before
working on electrical components!
Ni-Cr-Ni temperature senders require special cables which are supplied with the
senders!
WARNING:
All wires should be protected by small metal terminals to ensure a
lasting and safe connection to the ALPHAMFD. All cables and the Pitot tube
should be secured against pull. There is a special mounting bracket on the rear
of the ALPHA
ALPHAALPHA
ALPHAMFD for securing against pull.
7
When mounting the senders the following points must be observed:
• Protect the sender leads against high temperatures.
• Protect the sender leads from excessive vibration. However, a certain amount of
movement must be allowed.
• The sender leads must not be sharply bent or abraded.
• The threads of EGT, CHT, water- and oil temp senders must be treated with
Loctite Anti Seize (or a similar agent) to ensure trouble-free unscrewing.
Type K temperature senders (NiCrNi) MUST be extended with specially
compensated extension leads. If the leads of the senders are too short and must be
extended, the special Type K extension leads and Type K plug and sockets MUST be
used. These leads are available from
BRÄUNIGER
:
Type Pt100 temperature senders do not need specially compensated extension
leads but can be extended with standard copper leads.
Please observe, that the ALPHA
ALPHAALPHA
ALPHAMFD is equipped with two different types of
temperature ports: Type K and Pt100. These ports can ONLY be used with
the respective type of sender.
Please follow the technical information of the senders you are using.
NOTE:
BRÄUNIGER
provides complete cable looms and sender kits as an option for
some popular engines. With these connection kits, it is even easier to connect the
ALPHAMFD.
2.3.1 Switch-Off unused Temperature Ports
The ALPHA
ALPHAALPHA
ALPHAMFD has six different ports where temperature senders can be connected
(Two Type Pt100 and four Type K). Because with some engine configurations some
ports are not used, they can be switched off.
Because of their technical characteristics, temperature ports still show temperatures
even when no senders are attached, and these temperatures are of course "nonsense".
Therefore the ports can be switched off and "nonsense" values are suppressed.
8
Switching-off ports is done in SET-Modes 31 through 37.

35 CHT 1 Use CHT 1 Port YES / NO
36 CHT 2 Use CHT 2 Port YES / NO
37 Fuel flow Use Fuel Port YES / NO
Attention: Under set mode 37 it’s up from version 4.04 possible to
deactivate the fuel port. This may be helpful for trikes where the gas tank is
visible close to the pilot, or fuel systems with high flow back systems where
the flow sensor can’t work!
Note: The factory setting is all temperature ports ON!
WARNING: Make sure only unused temperature ports are switched
off! If a
used temperature port with a connected sender is accidentally switched off,
the temperature is not displayed and also the alarm function is
inoperative!

2.4 Mounting Fuel Flow Sender
2.4.1 General Notes
The fuel capacity indicator of the ALPHA
ALPHAALPHA
ALPHAMFD works with a special fuel flow sender.
We recommend only to use the sender supplied by
BRÄUNIGER
, because other
senders are not adapted to the ALPHA
ALPHAALPHA
ALPHAMFD and precise function can not be
guaranteed. The fuel flow senders transmits pluses according to the actual fuel
consumption to the ALPHA
ALPHAALPHA
ALPHAMFD. These pulses are added up to a fuel capacity
indicator. The sender can be used with all kinds of fuel.
11
The
BRÄUNIGER
fuel flow sender is looped in the fuel line between filter and engine.
Make sure all connections of fuel line are leak proof and secure. Secure all line
connections with suitable parts, e.g. hose clamps.
The fuel flow sender is designed in such a way, that even when the sensor wheel is
blocked, there is always enough fuel throughput to keep the engine running. Of course
the fuel flow can not be measured with a blocked sensor wheel.
2.4.2 Important Safety Notes
WARNING! To prevent air bubbles from getting stuck inside the fuel flow
sender, the sender MUST be mounted in an angle of optimal 90° and
minimum 60° relative to the longitudinal axis of the aircraft. Only this way a
precise measurement can be achieved. The direction of the fuel flow MUST be
from bottom to top! Take care of the correct flow direction indicated by the
arrow on the sender.
WARNING! The fuel flow sender MUST be mounted AFTER the fuel filter so
that foreign matter in the fuel cannot block the sensor wheel!
WARNING! When mounting the fuel flow sender you MUST observe the safety
and operation notes of the engine manufacturer!
2.4.3 Recommendations to Achieve Precision Measurements
Because most fuel pumps create strong vibrations in the fuel line and these vibration
can negatively influence the precision of the fuel flow sender, the sender should be
mounted far away from the fuel pump.
The fuel flow sender should be mounted close to the tank. The high temperatures in
the engine compartment can change the viscosity of the fuel which can negatively
influence measurement precision!

2.5 Pitot Tube and Static Port
There are 2 different pressure ports on the backside of the case:
2.5.1 Static Port
This is the port for the static pressure. It must be connected to the static port of the
aircraft. If you don't know where the static port of your aircraft is, ask the
manufacturer of the aircraft. A static pressure port is only necessary for aircraft with
closed passenger cabin. Open flex-wing Ultralights can leave the static port open
without connecting it anywhere.
2.5.2 Pitot Port
This is the port for the pitot pressure. The pitot tube of the aircraft is connected to the
pitot port. This is done with standard silicone hose. Check that the tube is neither
tangled nor sharply bent on its way from the pitot tube to the ALPHA
ALPHAALPHA
ALPHAMFD. The pitot
tube should be free of turbulences for precise measurements. The pitot should be
mounted parallel to the aerodynamic air flow during cruise flight.
Because the ideal mounting of the pitot tube is different for every aircraft type, please
contact your aircraft manufacturer for special information.
3 Power On and Built - In Self-Test (BIT)
By pressing the <ON/OFF>-key the instrument is switched on. For a short period of
time all segments of the LC-display are illuminated in order to test the function of the
display. Next the instrument goes into CHECK-Mode. An internal self-test is executed
and all senders are checked for correct signals. If the ALPHAMFD discovers a fault, it
displays an ERROR-code. A list of all possible ERROR-codes is listed in section 7.1.10 .
If everything is OK, you will see several "CHECK OK" messages and the instrument is
ready for operation. Among others the speed range (which is set by the factory) is
displayed. This is an additional safety check for the pilot.
4 Flight Management
4.1 Air Speed Indicator (IAS, CAS)
The ALPHAMFD has an easy to read large
analogue display of the air speed. By using a
standard Pitot tube the Indicated Air Speed (IAS) is
displayed. Note: IAS shows the speed in every
altitude according to the measured dynamic air
pressure. At high altitudes the actual True Air
Speed (TAS) is higher than the IAS. Displaying the
IAS has several advantages and is also required by
various aviation authorities. For example the speed
never to exceed (Vne) or the stall speed (Vso or
Vs1) can always be read at the same spot of the
14
scale at every altitude.
Standard, commercially available, Pitot tubes are used for speed-senders. The speed
indicator is calibrated by
BRÄUNIGER
according to the corresponding dynamic air
pressure.
4.1.1 Calibration of Air Speed (CAS)
The pilot can individually calibrate the speed indicator in SET-Mode 15 by adjusting the
SPEED GAIN factor. This way measurement errors, caused e.g. by a not optimal
position of the Pitot tube, can be individually corrected. After calibration, CAS
(Calibrated Air Speed) is indicated. The default value is >100<. If you adjust the
SPEED GAIN e.g. to <110> the speed indication will show a approx. 10% higher CAS.
The easiest way to calibrate the air speed indicator is to use a GPS. On a day with no
wind the Ground Speed is compared to the Indicated Air Speed. You should fly your
entire speed range, i.e. landing speed, medium speed, cruise speed and close to the
Vne. The differences in GS to IAS will probably vary through the speed range. It is
optimal to calibrate close to landing speed. It is also recommended to fly different
courses (e.g. 360°, 270°, 180° und 90°) to eliminate possible wind influences.
Additionally the speed zero point can be calibrated. This is done in SET-Mode 16
(SPEED ZERO).Press two times the “Enter” key.
.
WARNING!
The possibility to calibrate the Air Speed Indicator allows for a very accurate
calibration of the Calibrated Air Speed. But if the calibration is done
incorrectly, the CAS indication can show inaccurate speeds which can lead
to serious accidents (landing!) Therefore Aircraft manufacturers can
block the settings for Speed calibration. Stall and Vne for the user.
It is also highly recommended to calibrate the speed zero point every
2-3 months to preserve accuracy.
4.1.2 Speed Indication “Stretching Schemes” / Units Air Speed
The ALPHA
ALPHAALPHA
ALPHAMFD is available in 6 different versions:
Version Speed-Units Speed-Range VSI Units
Version A Km/h 40 – 220 km/h m/s
Version B Km/h 60-340 km/h m/s
Version C Knots or mph 24 –130 kts ft/min
Version D Knots or mph 32 – 190 kts ft/min
Knots-versions can be converted to mph-versions. This must be done at the factory.
Km/h-versions can also be converted to kts or mph versions. Again this must be done
at
BRÄUNIGER
.
15
WARNING: To get a precise indication of the air speed, some scales are
"stretched". Please note the different resolutions of the scales. The
increment between two marks can indicate speed differences from 2.5 km/h to
10 km/h!
Example:
ALPHA
ALPHAALPHA
ALPHAMFD version B (340 km/h) uses the following "stretching scheme":
• From 60 km/h to 110 km/h every mark indicates a speed resolution of 2,5 km/h
(important for precise indication of speed for landing or to prevent stalling)
• From 110 km/h to 210 km/h every mark indicates a speed resolution of 5 km/h
• From 210 km/h to 340 km/h every mark indicates a speed resolution of 10 km/h
Additional details in section 11 "Technical data"
In SET-Mode 17 two different pointer styles can be chosen according to personal
preferences: Sectional pointer or single pointer. More in section 4.4.1 and 4.4.2
Because it is very important to comprehend the different speed ranges at a single
glance, self adhesive coloured marker rings in white, green, yellow and red are
included with every ALPHAMFD. These rings can be mounted to the speed indicator
corresponding to the speeds of the individual aircraft (Vno, Vne, Vso, Vs1, etc.)
4.1.3 Stall-Alarm
Stall-Alarm: In SET-Mode 6 the visual and audio warning for stall speed in landing
configuration (Vso) can be programmed. After switching to SET-Mode by pressing the
>FUNC/SET< key (SF = special functions) for a few seconds, select SET-Mode 6 =
STALL ALARM by pressing the >ARROW<-keys. After pressing the >ENTER/MEMO<
key the <SET< icon will start flashing. Now the speed of the stall alarm can be
adjusted. By pressing >ENTER/MEMO< again, the new value is stored. Pressing the
>FUNC/SET< key leaves the SET-Mode. To change the value for stall alarm can be
blocked by the aircraft manufacturer.
16
4.1.4 Vne-Alarm
Vne-Alarm: In Set-Mode 7 the Velocity never to exceed is set in the same way as
described above,( if not blocked by the manufacturer) If you exceed this maximum
allowable speed an acoustic and visible (flashing speed pointer) is activated.
Note: Neither the Stall- nor the Vne - Alarm can be switched off.
WARNING! If the Indicated Air Speed is faster than 50 km/h, the
ALPHA
ALPHAALPHA
ALPHAMFD cannot be switched off! This prevents the pilot from accidentally
switching off the ALPHA
ALPHAALPHA
ALPHAMFD during flight.
4.2 Altimeter and Air Pressure
We recommend setting the correct QNH prior to every flight. This is easily done by just
pressing the ARROW up / down keys.
4.2.1 Altitude MSL (QNH)
Usually the altimeter is set to altitude above mean
sea level MSL. If the >m/ft/QNH/AGM< key is
pressed once, the display switches over from meter
to feet. If the same key is pressed again, the
corresponding QNH is displayed in hPa (or InHg).
4.2.2 Altitude above GND / AGL (QFE)
It is also possible to set the altimeter to zero while on the ground. This way the
altitude shows Above Ground Level (AGL or GND). When switching over to air pressure
while AGL is set, the ALPHAMFD automatically calculates the corresponding QFE. On
many airports the QNH is given by ATC prior to take-off. You can also set the QNH by
pressing the >ARROW< keys and the ALPHAMFD automatically calculates the
corresponding altitude above MSL. (Kollsman-Window)
4.2.3 Flight Level (FL, QNE)
In some air spaces pilots are required to fly by flight levels. All aircraft set their
altimeter to the ICAO standard air pressure of 1013,2 hPa.
The ALPHA
ALPHAALPHA
ALPHAMFD has a special function to set this very easily. By pressing the
>ARROW UP< and >ARROW DOWN< keys simultaneously, the altimeter is set very
quickly to 1013,2 hPa (QNE). Now the altitude is shown in flight level. Changing the
altitude to flight level is indicated by "QNE" in the display.
If you want to revert to altitude MSL, just get the new actual QNH from the nearest air
field and adjust the altimeter accordingly using the >ARROW< keys.
4.3 Altitude Guidance Mode (AGM)
The Altitude Guidance Mode (AGM) helps pilots to maintain a chosen altitude with the
help of an acoustic alarm. If the chosen altitude is exceeded, either too high or too
17
low, by a difference set in the SET-Mode 5, an audio alarm starts to sound through the
Intercom and the altitude display starts flashing.
Example: A pilot flies 2000 ft MSL and wants to maintain this altitude for a longer
period of time because he would otherwise enter controlled airspace when flying
higher. He doesn't want to check the altimeter all the time so he activates AGM which
will warn him if he flies too high or too low. The altitude difference which triggers the
alarm can be set in SET-Mode 5. As soon as the desired altitude to be maintained is
reached, the AGM is activated by pressing >m/ft/QNH/AGM< for several seconds.
The display shows <AGM ON>.
By pressing >m/ft/QNH/AGM< again for several seconds, AGM is deactivated and
<AGM OFF> is displayed.
Example:
2000 ft shall be maintained. Altitude difference of 200 ft or greater above 2000 ft and
200 ft and greater below 2000 ft will trigger the audio alarm. As soon as the pilot
inadvertently climbs to 2200 ft and more, the alarm goes off and the altitude display
starts flashing. The same happens if the pilots descends to 1800 ft or less. As soon as
the pilot returns to within the desired altitude range (2000 ft + 200 ft or – 200 ft), the
alarm stops automatically and the altitude display stops flashing.
The altitude range is set in SET-Mode 5, the set value represents the maximum
allowed altitude difference for above and below the desired altitude
4.4 VSI (Vertical Speed Indicator)
Climbing or descending speeds are shown on a large, easy to read, analogue display
with a resolution of 0.25 m/s. Values between +/- 10 m/s are displayed (or the
equivalent in ft/min)
The ALPHAMFD has two different ways of indication values on the round analogue
scales. They can be chosen according to personal preferences in SET-Mode 17.
4.4.1 Single Pointer Display
The Single Pointer Display indicates rate of climb or sink with a conventional single
pointer. If the climb or sink rate exceeds +/- 5 m/s, the values from 5 m/s to 10 m/s
are displayed in a second stage which is indicated by a second pointer at 5 m/s.

4.4.2 Sector Display
The Sector Display indicates climb or sink rate by an
"increasing" sector. If the climb or sink rate exceeds +/5 m/s, the values from 5 m/s to 10 m/s are displayed in
a second stage which is indicated by the sector being
cleared. We recommend using the Sector Display in low
temperatures, because in low temperatures the LCdisplay becomes slow and the Sector Display is better to
read.
The VSI of the ALPHAMFD works electronically and therefore works much faster,
crisper and more precise compared to conventional mechanical VSI instruments with
their inherent long time lag.
4.4.3 Variometer Acoustic
If the motor of the airplane is switched off and the unit is climbing an acoustic signal
will be transferred to the intercom. A stronger climbing corresponds to higher
frequency and faster beep intervals.
4.5 Flight Time, Take-Off Time and Date of Flight
The flight time is measured as soon as the speed exceeds 50 km/h IAS. This moment
is also registered as take-off time and can later be called up in the MEMO-Mode. The
flight time is stopped as soon as the ALPHAMFD registers speeds of less than 50
km/h IAS.
WARNING! The ALPHA
ALPHAALPHA
ALPHAMFD cannot be switched off as long as it registers
an air speed of faster than 50 km/h. This prevents the pilot from
inadvertently switching off the instrument during flight.
4.6 Temperature and Voltmeter
By pressing the >FUNC/SET< key twice (with interval inbetween), the altimeter
display is switched to voltmeter and temperature. In SET-Mode 22 (UNIT
TEMPERATURE) you can choose between °C Celsius or °F Fahrenheit.
WARNING! The ALPHAMFD measures the temperature of the instrument
board (which approx. corresponds to outside temperature in open flex-wing
ultralights/microlights or the cabin temperature of closed fix-wing ULs). The
indicated temperature is not the actual outside temperature OAT. The
temperature is used for internal temperature compensation. It may NOT be
used for calculations of correcting factors to ICAO standard
atmosphere (density altitude). It is only suitable for information!
19
At the same time the actual voltage of the aircraft system
is displayed. After a few seconds both displays switch back
to altitude and real-time. When the ALPHAMFD switches
over to emergency power for any reason, the Voltmeter
indicates the voltage of the back-up battery.
WARNING! When the ALPHAMFD switches over to emergency power
supply by the back-up battery, the voltage of the back-up battery is indicated.
If this value drops to 7,2 V or below you must IMMEDIATELY exchange the
battery. You MUST NOT fly with a voltage of 7.2 V or below because the
emergency power supply can not be guaranteed!
4.7 Real-Time
The time is shown in hh:mm.
Time and date are set in SET-Modes 19, 20, and 21.
5 Engine Management
5.1 Engine RPM
Engine RPM is digitally indicated to max. 9980 RPM
with a resolution of 20 RPM.
5.1.1 RPM Measurement RPM Port
Most engines have a dedicated 12 V port for measuring the engine RPM. In SET-Mode
18 the ALPHA
ALPHAALPHA
ALPHAMFD can be programmed to read the RPM signal depending on engine
type and ignition sequence. It is possible to set a factor "multiplied by 4, 2, or 1 or
"divided by 6, 4, 3, 2".
The generators of Rotax 582 and 503 engines give 6 pulses per revolution, so the
ALPHA
ALPHAALPHA
ALPHAMFD must be set to "divided by 6" for use with these engines.
WARNING! Do not disconnect the power supply of the ALPHA
ALPHAALPHA
ALPHAMFD before
switching it off. If the ALPHA
ALPHAALPHA
ALPHAMFD is disconnected before it is switched off, it
cannot write information (like engine hours) into its memory and the values
are permanently lost. It will switch over to the emergency power supply and
unnecessarily drains the back-up battery!
20
For Rotax 912 engines the factor must be set to *1.
The factors for other engines can be obtained from their manufacturers.
Because some engines use a special RPM signal, the ALPHA
ALPHAALPHA
ALPHAMFD can be programmed
to understand this signal with a filter. This filter can be activated or deactivated in SETMode 27 (Default is ROTAX). This enables the unit to understand pulses from 6 … 200
Volts.
WARNING! As long as the ALPHA
ALPHAALPHA
ALPHAMFD reads RPM from a running engine, it
cannot be switched off. This is to prevent the pilot to inadvertently switch off
the instrument during flight.
5.1.2 Capacitive RPM Measurement at ignition cable
(This function is not supported any longer)
5.2 Engine Hour Meter
The ALPHAMFD distinguishes between flight time and engine running time per flight.
Both values are displayed and stored for every flight. They can be recalled in MEMO-
Mode (see section 6) with a resolution of 1 minute.
Additionally, the total running time of the engine of all flights (Engine Hour Meter) is
displayed in SET-Mode 4. This value can not be changed and does not get lost when
disconnecting the power of the ALPHAMFD. The value is shown in full hours.
WARNING! Never disconnect the ALPHAMFD from its power supply before
switching it off. If it is disconnected from the power supply without prior
switching it off, it cannot store some information (e.g. engine hours) in its
memory. Important data will be lost!
5.3 Fuel State and Fuel Flow (Consumption)
5.3.1 Important Safety Information
The fuel state is determined by a special flow sender. It is highly recommended to only
use the flow sender supplied by
BRÄUNIGER
, because other senders are not adapted
to the ALPHAMFD and correct function cannot be guaranteed.
21
5.3.2 Fuel Flow Meter
The BRÄUNIGER fuel flow sender is looped into the fuel line between engine and fuel
filter. For details see section 2.4.
WARNING! The fuel flow sender must be installed AFTER the fuel filter, so
that foreign matter and dirt in the fuel cannot block the sensor wheel. The fuel
flow sender MUST be installed in an angle between 60° and 90°
relative to
the longitudinal axis of the aircraft. The fuel must flow from bottom to top.
Please observe the mounting instructions in section 2.4!
The sender is designed in such a way, that even when the sensor wheel is blocked, the
engine still gets enough fuel for running. A fuel measurement is of course not possible
with a blocked sensor wheel.
The fuel flow sender transmits pulses to the ALPHA
ALPHAALPHA
ALPHAMFD according to the actual fuel
consumption. The ALPHA
ALPHAALPHA
ALPHAMFD converts these pulses to the fuel flow and fuel state
indication.
WARNING! After filling up the aircraft, the actual contents of the tank
must be input into the ALPHA
ALPHAALPHA
ALPHAMFD (see section 5.3.8). If the pilot forgets
to input this correctly, the fuel state indication is INCORRECT!
WARNING! IMPORTANT SAFETY INFORMATION!
The Fuel Flow Meter has been designed with very precise industrial
measuring devices. During practical tests and calibration trials it became
evident, that the entire system can be very precisely calibrated. But external
factors, such as temperature of fuel can negatively influence the precision.
Even different fuel versions with their inherent differences in viscosity can
degrade precision of measurement.
Although the fuel flow meter and fuel state are relatively precise, the pilot in
command must check the fuel prior to flight
and must make sure there is
enough fuel in the tanks for the planned flight. The fuel state indication of
the ALPHA
ALPHAALPHA
ALPHAMFD does not relieve the pilot from completing prudent
range calculations during flight planning!
The fuel flow meter and fuel state are only to be taken as additional
information for the pilot. Negative external factors, the incorrect operation
of the system or a break down of the ALPHA
ALPHAALPHA
ALPHAMFD can lead to the indication
of INCORRECT values!
22
5.3.3 Precision of Fuel Flow
The highest precision is achieved with normal RPM during cruise flight (Fuel
consumption between 10 and 20 l/h). In the extreme corners of the RPM range, e.g.
during full throttle or idle, the precision is slightly less. Below a fuel consumption of 5
litres/h the precision is rather low, therefore the ALPHA
ALPHAALPHA
ALPHAMFD does not indicate a fuel
consumption below 5 litres/h. It always assumes a minimum fuel consumption of 5
litres/h, even when the engine idles.
5.3.4 Fuel Flow with Engines with Fuel Flow-Back System
Certain engine configurations not only have a fuel line from tank to engine, but fuel
which is not consumed by the engine is transported back from engine to tank.
5.3.5 Measuring with two flow senders (engines with fuel flow back system)
Because the back-flow can be a significant portion of the fuel pumped to the engine,
the ALPHA
ALPHAALPHA
ALPHAMFD can be used with a second fuel flow sender. The ALPHA
ALPHAALPHA
ALPHAMFD
measures the fuel flow from tank to engine and also from engine back to tank. Both
values let the ALPHA
ALPHAALPHA
ALPHAMFD calculate the actual fuel consumption.
In SET-Mode 37 the ALPHA
ALPHAALPHA
ALPHAMFD can be programmed, whether the aircraft uses a
single fuel line (tank to engine, setting 1WAY) or a fuel flow back system (setting
2WAY).
Even when two senders are used, the fuel flow can be calibrated as described in
section 5.3.6
WARNING! Because two fuel flow senders are used with engines with fuel
flow-back configuration, possible measuring errors could duplicate.
Therefore the precision is lower than with only a single fuel line in 1-way
configurations and we do not recommend to use two flow senders.
5.3.6 Recommended: Measuring with one fuel flow sender (engines with fuel flow
back system)
There is a second way of measuring the fuel consumption of engines with a fuel flow
back system. This works with engines, where the fuel line is split to two carburettors
AFTER the fuel line which leads back to the tank (e.g. some Rotax 912 and 912 S
versions). Because it can be assumed that both carburettors receive approximately the
same amount of fuel, only the fuel consumption of one carburettor is measured and
then doubled.
The calibration factor in SET-Mode 3 must be set to double the indicated fuel flow. A
setting of approx. 140-170 has shown to be right in various tests
The measuring method must be set to 1WAY in SET-Mode 38.
23
WARNING: We recommend using the measuring method with only
one fuel flow sender for engines with a fuel flow back system. The
indicated values are not only more precise than when using two senders, you
only have to buy and mount one sender.
5.3.7 Display of Fuel Flow
By pressing the >FUNC/SET< key briefly, the altitude display is temporarily replaced
by the fuel flow in either litres/hour or US-Gallon/hour. Pressing >FUNC/SET< again
will switch back to altitude. The fuel flow units can be changed in SET-Mode 25 from
litres/h to US-Gallon/h. For details see section 7.6.
The fuel flow indication is averaged. If the RPM of the engine is changed, it
can take a few seconds until the new fuel flow is indicated.
If the >FUNC/SET< key is not pressed a second time, for safety reasons the
display automatically reverts to altitude after a few seconds.
5.3.8 Calibration of Fuel Flow Meter
Because the fuel systems are different in every aircraft, we recommend calibration of
the fuel flow meter. This can be done in SET-Mode 3. The default value is a factor of
Carburettor
Flow Sender
Fuel line engine to tank
Fuel line from tank to engine
Motor
Engine
Recommended way of measuring
:
Measuring fuel flow with ONE Fuel Flow Sender for engines with fuel flow back system
24
100%. If the factor is increased, a higher fuel flow will be displayed. If the factor is
decreased, a lower fuel flow is indicated.
Factor > 100 = higher fuel flow indication
Factor < 100 = lower fuel flow indication
WARNING! If the calibration is done incorrectly, the ALPHA
ALPHAALPHA
ALPHAMFD will
indicate INCORRECT fuel flow and tank state!
5.3.9 Display of Fuel State
The maximum tank capacity is set in SET-Mode 2. The fuel state is
displayed with a easy to read bar graph, one bar of the graph
represents 10% of the maximum fuel capacity. 10 bars represent
100% = tank full, 1 bar represents 10% = reserve! The fuel state is
not measured directly in the tank but is computed from tank
capacity and fuel flow. When 10% are reached, an audio and visuell
alarm is sounded through the Intercom and the 10% bar starts
flashing. Just before the tank is empty, all bars start to flash and
the Intercom-Alarm is sounded.
5.3.10 How to enter the Actual Fuel State after filling up
Switch to SET-Mode 1 by pressing the >FUNC/SET< key for a few seconds. After
pressing >ENTER/MEMO< the >SET< icon starts to flash. This indicates that a value
can be changed. Now the maximum tank capacity is displayed. If you have really filled
up the tank just press >ENTER/MEMO< again and the value for full tank is stored.
If the tank is not filled up completely (e.g. when filling up from Jerry cans) you can
also store any value you want (in Litres or US-Gallons). The desired value is adjusted
by pressing the >ARROW< keys.
WARNING! If INCORRECT values are put into the ALPHA
ALPHAALPHA
ALPHAMFD, there will
also be INCORRECT values indicated by the ALPHA
ALPHAALPHA
ALPHAMFD!
5.4 Cylinder Head Temperature (CHT) and Exhaust Gas Temperature
(EGT)
The temperatures of two cylinders are simultaneously monitored by the ALPHA
ALPHAALPHA
ALPHAMFD
with standard NiCrNi thermoelements (Type K). By pressing the >TEMP< key, the
exhaust gas temperature (EGT), the cylinder head temperature (CHT) and oil and
water temperature can be displayed.
Of course the four Type K ports of the ALPHA
ALPHAALPHA
ALPHAMFD can also be used differently, e.g.
for monitoring the EGT of 4 cylinders. This mode can be set in SET-Mode 28. In this
25
mode (EGT SCROLL MODE) the EGT-values of 4 cylinders, the oil temperature and
water temperature are scrolled in the display. The actual temperature is displayed in
the top field of the temperature fields, the bottom field shows the corresponding
cylinder, e.g. CL1 for cylinder 1, CL2 for cylinder 2, etc. The oil temperature is
indicated by OIL and the water temperature by H2O. Oil and water are only displayed,
if the corresponding ports are activated (see section 2.3.1).
Type K thermoelements and –ports are suitable for monitoring high temperatures, e.g.
CHT or EGT. For water and oil temperatures usually Pt100 senders are used, because
they have a better resolution and precision at lower temperatures. The ALPHA
ALPHAALPHA
ALPHAMFD
has 4 Type K ports and 2 Pt100 ports.
The ALPHA
ALPHAALPHA
ALPHAMFD constantly monitors all senders for faults, e.g. cable breaks. If an
error is found, the audio alarm is sounded through the Intercom and the respective
display starts flashing. The display of temperatures is substituted by three dashes (---).
Because of the way temperature senders work, they can only show a signal which
corresponds to a difference in temperature of the source and a comparison point. To
show the real actual temperature, the difference value must be compensated by the
outside air temperature. The ALPHA
ALPHAALPHA
ALPHAMFD does this all the time with an internal
temperature sender.
WARNING!
As mentioned in section 2.3.1, unused temperature ports can be
deactivated in Set-Mode 31 to 36 in order to de-clutter the display. If a
temperature is not displayed even though a sender has been connected
correctly, check if the port has not mistakenly been deactivated!
5.5 Water Temperature
The water temperature is usually measured by a Pt100 temperature sender. It is
displayed in the TOP temperature field of the ALPHA
ALPHAALPHA
ALPHAMFD display and is designated
by the >Water/Oil Temp< icon. With some engines, e.g. Rotax 912, CHT and water
temperature are measured together, i.e. the water temperature is measured at two
cylinder heads. In this case it is recommended using two Type K senders at the two
CHT ports of the ALPHA
ALPHAALPHA
ALPHAMFD.
5.6 Oil Temperature
The oil temperature is measured with a Pt100 sender. The sender is connected to the
Pt100 Oil Temp port on the ALPHA
ALPHAALPHA
ALPHAMFD. It is displayed in the LOWER temperature
field of the ALPHA
ALPHAALPHA
ALPHAMFD display and is also designated by the >Water/Oil Temp<
icon. For further details see the following section 5.7.
26
5.7 Display of Temperatures
The temperature display fields are scrolled by pressing the >TEMP< key. Pressing
repeatedly switches to the next temperature. The displayed pair of temperatures is
designated by the Icons >CHT<, >EGT<, or >Water/Oil Temp<.
EGT 1 CHT 1 Water EGT 1 etc.
EGT 2 CHT 2 Oil EGT 2 etc.
In case the EGT Scroll Mode is activated in SETMode 28, the top field shows the actual temperatures and the lower field shows the
cylinder designation, e.g. CL1, CL2, etc. Water Temperature is designated by H2O and
Oil is designated by OIL.
Because the ALPHA
ALPHAALPHA
ALPHAMFD constantly monitors ALL engine temperatures, it is not
necessary to display all temperatures on the display. This would clutter the display and
make it very hard to read (information overload!). The pilot can choose the
temperature pair which interests him most. All other temperatures are still
monitored even when not displayed. If a temperature value is exceeded according
to the programmed max values, an alarm tone is sounded through the Intercom the
red alarm light is flashing and the excessive value is displayed together with its
designator (Icon) so it can easily be identified.
Attention: To stop the annoying sound and flash light and to come back from an
alarm temperature to see another one, for example EGT to CHT, first press the
ON/OFF button surpressing the audio/video alarm, than press the EGT/CHT button!
Note: The instrument is not switched off during flight when pressing the >ON/OFF<
key!
5.8 Oil Pressure and Low Oil Pressure Warning
The ALPHA
ALPHAALPHA
ALPHAMFD can monitor oil pressure in two different ways, depending on the
type of the oil pressure sender being used: You have to set the type of oil pressure
sender in SET-Mode 29.
SET-Mode Options:
DIGI = Oil pressure switch (On/Off)
ANA = Analogue oil pressure sender (e.g. Rotax 912)
WARNING! If the INCORRECT type of oil pressure sender is set, the oil
pressure is NOT MONITORED! There will be no warning if something goes
wrong with the oil pressure!
5.8.1 Oil Pressure Switch
The oil pressure switch does not monitor the exact oil pressure, but indicates when the
permissible oil pressure drops below a certain value. This value is built into the switch
and cannot be set in the ALPHA
ALPHAALPHA
ALPHAMFD.
27
When starting the engine, the >OIL< Icon is illuminated. This can last up to approx.
15 seconds after starting the engine. This is not a warning, but shows, that the engine
has not yet reached the operation oil pressure. As soon as the normal operating oil
pressure is reached, the icon extinguishes.
If the >OIL< icon together with the red alarm light start flashing during
flight and an alarm is sounded through the Intercom, the oil pressure is too
LOW!
5.8.2 Analogue Oil Pressure Sender
If an analogue oil pressure sender is used, the ALPHA
ALPHAALPHA
ALPHAMFD indicates the exact oil
pressure in bar (or PSI). The value is displayed in the right hand corner of the display
in the following formats:
Example:
5:7 represents an oil pressure of 5,7 bar
10:3 represents an oil pressure of 10,3 bar
25 represents an oil pressure of 25 PSI
56 represents an oil pressure of 56 PSI
The oil pressure is displayed with 3 digits and a resolution of 0.2 bar (or 2 PSI). The oil
pressure unit can be set in SET-Mode 26, bar or PSI is possible.
The ALPHA
ALPHAALPHA
ALPHAMFD is designed to be used with the VDO Oil Pressure sender. It
will not indicate correct values with other types of oil pressure senders.
The ALPHA
ALPHAALPHA
ALPHAMFD monitors the minimum and maximum permissible oil pressure
values. They can be set in SET-Mode 13 and 14. If the values are exceeded, the
>OIL< icon and the oil pressure display start to flash and an alarm is sounded through
the Intercom. If the oil pressure display is not activated at the time of the alarm (e.g.
the flight time is displayed instead), the oil pressure display automatically shows up.
The oil pressure display can be activated by pressing the >ENTER/MEMO< key, the
display is designated by the >OIL< icon.
If the engine is started, the oil pressure display is automatically activated and the oil
pressure is shown for approx. 15 seconds. If the engine reaches the normal operating
oil pressure range (defined by the minimum and maximum values in SET-Mode 13 and
14) during those 15 seconds, the display switches back to the previously selected
display (e.g. flight time).
If during flight the oil pressure drops below the minimum oil pressure or
exceeds the maximum oil pressure, the >OIL< icon and the oil pressure
display and the red alarm light start to flash and an alarm is sounded
through the Intercom. If the oil pressure display is not activated at the time
of the alarm (e.g. the flight time is displayed instead), the oil pressure
display automatically shows up.
28
5.9 Voltmeter
After pressing the >FUNC/SET< key twice, the altitude
display changes to temperature and the real-time display
changes to voltage indicated by the >VOLT< icon. If the
voltage of the aircraft drops below 11.5 V an audio/video
alarm sounds through the Intercom and the real-time display alternates with the
voltmeter display. If the ALPHAMFD switches to emergency power supply, the
voltage of the back-up battery will be displayed.
5.10 Back-Up Power Supply
If the aircraft power was cut off during flight, the ALPHA
ALPHAALPHA
ALPHAMFD would stop working.
Therefore the ALPHA
ALPHAALPHA
ALPHAMFD has an integrated back-up power supply. The instrument
switches automatically over to the back-up battery when the normal power supply
drops below the safety margin of 11.0 V or is cut off completely. The switch to back-up
battery is indicated by an alarm through the Intercom the flashing of the voltmeter
display and the red alarm flashlight.
The back-up battery is a normal 9V alkali-manganese 6LR61 block, which is stored in a
compartment on the side of the instrument. It can easily be replaced by opening the
drawer.
The ALPHA
ALPHAALPHA
ALPHAMFD checks the back-up battery every time it is switched on. If the
voltage of the back-up battery is too low and not sufficient to power the ALPHA
ALPHAALPHA
ALPHAMFD
in case of emergency, the message "BACK-UP BATTERY LOW" is displayed. The backup battery must be replaced as soon as possible!
For safety reasons, the ALPHA
ALPHAALPHA
ALPHAMFD can only be switched on when the normal aircraft
power supply is sufficient. It will only switch over to the back-up battery, when the
aircraft power supply is faulty during flight. This way the pilot cannot take off with a
faulty aircraft power supply!
WARNING! When the ALPHAMFD switches over to emergency power
supply by the back-up battery, the voltage of the back-up battery is indicated.
If this value drops to 7,2 V or below you must IMMEDIATELY exchange the
battery. You MUST NOT fly with a voltage of 7.2 V or below because the
emergency power supply can not be guaranteed!
WARNING! Depending on the wiring of the ALPHAMFD connection, the
ALPHAMFD might be completely disconnected from the aircraft power supply.
If you switch off your engine, the main power supply can be interrupted and the
ALPHAMFD will switch to emergency power supply. In this case, the
ALPHAMFD
will switch off automatically after 3 minutes. This will only happen,
29
is measured, the ALPHAMFD
will NOT switch off automatically. This is a power
saving feature so the back-up battery is not drained early when the aircraft is
parking.
WARNING! For safety reasons the back-up battery should be
replaced once a
year, no matter how much voltage is left!
6 Flight Data Recorder
6.1 MEMO-Mode
The modern processor technology of the ALPHAMFD allows storage of the flight data
of the last 25 flights. After pressing the >ENTER/MEMO< key for several seconds,
the instrument switches to MEMO-Mode.
The MEMO-Mode shows the following information:
• Maximum rate of climb and sink
• Maximum engine temperatures: CHT, EGT, water temperature and oil temperatures
switch by pressing >TEMP<
• Maximum speed IAS
• Maximum RPM
• Maximum altitude
• Date of flight
• Take-off time (as soon as 50 km/h IAS are exceeded)
• Flight time and engine running time during flight, switch by pressing
>ENTER/MEMO<
Note: A flight is only saved as a flight if the engine runs for at least 1 minute and an
altitude change of at least 25 m is detected.
By pressing the >ARROW< keys you can scroll through the last 25 flights and call up
the corresponding maximum values. The flight can be identified by date. Additionally
the internal flight number is displayed for a short period of time in the RPM display. If
the memory is filled with 25 flights, the oldest flight no. 25 is erased when a new flight
is made. The new flight becomes no. 1.
Pressing the >FUNC/SET< key leaves the MEMO-Mode.
WARNING! For safety reasons the you cannot switch to MEMO-Mode if the
ALPHAMFD measures an Air Speed of 50 km/h and above.

7 Other Functions
7.1 Acoustic and Optical Warnings
Acoustic Alarms:
The ALPHAMFD has a special port for connecting to the Intercom (see section
2.3.3). The alarm, when sounded, consists of several short beeps. The beeps are
repeated every 30 seconds until the pilot switches the alarm off by pressing
>ON/OFF<.
Note: The instrument is not switched off during flight when pressing the
>ON/OFF< key!
Optical Alarms – MASTER Alarm:
Optical Alarms are always represented by flashing display fields. If e.g. an engine
temperature gets too high, the respective data field starts to flash. If the data field is
not activated, i.e. it is not displayed at the time of the alarm, the data field will
automatically be displayed. Up from Version 4.05 the ALPHA has an integrated optical
MASTER alarm which is placed in the left upper corner of the instruments panel, close
the “Bräuniger” Logo. It’s a flashing high power red light LED with 2 kind of alarms:
1. Fast flashing for STALL and VNE. This alarm cannot be switched off.
2. Slow flashing for other alarms. This flashing can be confirmed by pressing the
on/off button and quits the optical and acoustic alarm.
The following audio/optical alarms are implemented:
7.1.1 Stall-Alarm and VNE-Alarm
When the aircraft flies slower than the set stall speed (e.g. Vso) (adjusted in SET-Mode
6), or flies faster than the set maximum Speed Vne (adjusted in SET-Mode 7) an
acoustic alarm sounds. This sound (low frequency beeps) only stops when the stall
speed is exceeded or the Vne is falling short of. The alarm can not be switched off.
Below 44 km/h the stall alarm is not active.
7.1.2 Low Voltage
If the power supply of the aircraft drops below 12 V a single alarm sounds (several
beeps) through the Intercom. Additionally the real-time display alternates with the
voltmeter. This alarm is also activated, when the ALPHA
ALPHAALPHA
ALPHAMFD switches over to the
back-up battery. In this case, the voltage of the back-up battery is displayed.
7.1.3 Low Fuel
If the fuel gets below the 10% reserve mark, a single alarm sounds through the
Intercom and the 10% bar starts to flash. If the fuel gets even lower, this critical
condition is signalled by the continuous repetition of alarm beeps in the Intercom.
Additionally all bars of the fuel display start to flash
7.1.4 Cable Breakage of Temperature Senders
If the system detects a cable breakage of a temperature sender, an audio/optical
alarm is sounded through the Intercom and the corresponding display field starts to
flash. The temperature read-outs are replaced by 3 dashes (---).
31
7.1.5 Engine Temperatures too high
If the engine temperature thresholds are exceeded (can be defined in SET-Mode 8, 9,
and 10) the audio/optical alarm sounds and the corresponding temperature read-out
starts to flash. The temperatures continue to be displayed.
7.1.6 Altitude Guidance Mode
The AGM is an audio warning system which helps pilots to maintain a certain altitude
without having to permanently check the altimeter. Detailed information on the AGM
can be found in section 4.3.
7.1.7 Oil Pressure too low or too high
If the oil pressure drops below the minimum oil pressure (SET-Mode 12) or exceeds
the maximum oil pressure (SET-Mode 13), the alarm shows up. This works only with
an analogue oil pressure sender. If a oil pressure switch is used, the alarm is activated
only when the oil pressure drops below a certain threshold defined by the switch.
7.1.8 RPM too high
If the maximum RPM are exceeded (set in SET-Mode 11), the alarm is activated and
the RPM display starts flashing. The actual RPM are still displayed.
7.1.9 ERORR-Messages during Power on Self-Test (BIT)
The ALPHAMFD performs an automatic Self-Test when powering up. All senders are
checked for plausible and correct data and the instrument checks itself.
32
If the ALPHAMFD detects a problem, an ERROR-Code will be displayed.

7.2 Theft prevention and Password
Every ALPHAMFD is identified by a unique, unchangeable serial number (can be
called up in SET-Mode 40). Every customer receives an alphanumeric password with
his ALPHAMFD. The theft prevention function is not activated by default. It can be
activated in SET-Mode 30. For this you have to enter the password. Serial number and
corresponding password are printed on the back cover of this operating manual and on
your original invoice.
7.2.1 Password Function "Off"
SET-MODE >OFF<
The password is deactivated, the ALPHA
ALPHAALPHA
ALPHAMFD can be switched on without entering
the password. This is the default condition.
There are two different password functions. They can be selected in SET-Mode 30:
After pressing <ENTER> the SET symbol flashes. Press the Arrow Up button.
. "AAAAA" is displayed where every "A" must be replaced by the correct digit/letter by
pressing the <ARROW> keys and scrolling through the alphabet. Arrow up scrolls
through the letters and arrow down scrolls through the numbers. After entering each
letter/digit confirm by pressing <ENTER/MEMO> and the instrument will jump to the
next character. After entering the 5th letter and confirming with <ENTER> the unit will
display the first password function: “NOPWR” When pressing <Arrow up> it
shows the second password function “ON”
7.2.2 Password-Function "Car Radio"
SET-MODE >NOPWR<
Operation: After disconnecting the ALPHAMFD from the power supply (just as if
someone took it out the aircraft) the instrument is being locked and can not be used
without first entering the correct password.
If the instrument is connected to power again and switched on, the password must be
entered. "AAAAA" is displayed same way as mentioned above.
7.2.3 Password Function "Maximum"
SET-MODE >ON<
This mode gives maximum theft protection, not only of the ALPHA
ALPHAALPHA
ALPHAMFD itself but also
for the entire aircraft assuming it can not be flown without air speed indicator and
other vital indications.
The password must be entered EVERYTIME the AAAALPHA
LPHALPHA
LPHAMFD is switched on.
34
When the ALPHA
ALPHAALPHA
ALPHAMFD is switched on, "AAAAA" is displayed where every "A" must be
replaced by the correct digit/letter by pressing the >ARROW< keys and scrolling
through the alphabet. After entering each letter/digit confirm by pressing
>ENTER/MEMO< and the instrument will jump to the next character.
WARNING! A forgotten password can only be obtained from the manufacturer.
Proof of ownership (invoice) must be produced without exception. This Service
is not free and you must expect to be billed!
The password function can be disabled in Set-Mode 30 (OFF), but the correct
password must be entered prior to deactivation!
7.3 Selection of Units
In order to be able to use the ALPHAMFD internationally, the units of all numerically
displayed values, such as temperatures, air pressure, fuel and fuel consumption, and
altitude can be changed.
Engine temperature and cabin/instrument
temperature:
°C Celsius or °F Fahrenheit
Air pressure: hPa or inHg
Oil pressure: Bar or PSI
Altitude Meter or Feet
Fuel and fuel consumption Litres and litres/h or US-gallon and US-
gallon/h
7.4 Software Update
The internal software of the ALPHAMFD is continuously being improved. Because the
ALPHAMFD works with modern processors and flash-memory technology, it can be
upgraded to the latest software version at any time. You merely have to send the
instrument back to the manufacturer. Because of the possibility for software upgrades,
every ALPHAMFD is a safe long-term investment.
8 SET-Mode
In order to use the many functions of the ALPHAMFD and to be able to adjust it to
one's personal needs and preferences, some functions can be individually adjusted.
The SET-Mode is activated by pressing the >FUNC/SET< key for several seconds.
Once the SET-Mode is activated, a >SET< icon appears in the display With the
>ARROW< keys you can scroll through the SET-menus. A SET-Mode number is
displayed, so it is easier to get oriented.
35
If you want to change a function, press the >ENTER/MEMO< key. Now the >SET<
icon starts to flash which indicates that a value or setting can be changed by pressing
the >ARROW< keys. Pressing the >ENTER/MEMO< key again stores the new
setting. If the new settings shall not be stored, press >FUNC/SET< instead of
>ENTER/MEMO<. Also if you want to leave the SET-Mode, press >FUNC/SET<.
WARNING! For safety reasons the you cannot switch to SET-Mode if the
ALPHAMFD measures an Air Speed of 50 km/h and above.

9.4 Notes on using the ALPHA
ALPHAALPHA
ALPHAMFD on flex-wing Ultralights
The ALPHA
ALPHAALPHA
ALPHAMFD is also very well suited for using it with flex-
wing Ultralights. We recommend using the special
ALPHA
ALPHAALPHA
ALPHAMFD Pod.
Because the instrument is not protected on flex-wing
Ultralights by a closed compartment, under certain climatic
circumstances it can happen, that water condenses in the
ALPHA
ALPHAALPHA
ALPHAMFD. Normally this is no reason for worry, because
the condensed water usually evaporates within a short period
of time. If it doesn't, bring the ALPHA
ALPHAALPHA
ALPHAMFD to a warm and
dry place (park the aircraft in the sun).
We highly recommend covering the ALPHA
ALPHAALPHA
ALPHAMFD and Pod with a protective
cover during parking!
10 Periodical Check
Although the ALPHAMFD works completely maintenance free, we recommend
sending it every 3 years to the manufacturer for checking and calibration. Thus the
precise operation of your ALPHAMFD is maintained for a long period of time.
Additionally it can be upgraded to the latest software version.

Backlight
Up from Version 4.05 the ALPHA has an EL-backlight illumination. This backlight uses a
separate power connector. The connecting voltage is 12 VDC. Power consumption is at
70 mA. The backlight should be connected to any night light switch of the plane.
Attention
Don’t switch on the backlight during day light flights with ambient
temperatures higher than 30 °C. The backlight may heat up the
instrument under high day light temperatures and reduces the display
contrast.
Under winter temperatures below zero degrees the backlight is helpful
for avoiding any display delay which is normal at all LCD in subfreezing
conditions
12 Warranty
BRÄUNIGER
offers a 24 month international warranty on material and workmanship
on all ALPHAMFD from the date of purchase. In case of repair please send
instrument directly to
BRÄUNIGER
or to the nearest
BRÄUNIGER
Service Centre.
NOTES:
High Voltage protection for ALPHA
ALPHAALPHA
ALPHAMFD
To avoid damages by high voltage causing by defective voltage regulators the AlphaMFD has since 2002 an integrated voltage protection circuit.
In case of a defect voltage regulator the external fuse will fail and the ALPHAMFD is
supplied by the 9 volt back-up battery – battery display is blinking now.
After repair, please replace the defect fuse ( 150 … 200 mA )

WARNING
The activity of flying can be dangerous and can result in personal injury including
death. No instrument and no aircraft is perfect. In rare occasions it can happen that
instruments fail or show incorrect values. The pilot in command is always fully
responsible for a safe conduct of all flights.
BRÄUNIGER
assumes no liability!
Prior to operating the ALPHA
ALPHAALPHA
ALPHAMFD, the operating manual must be carefully read. If
something is unclear you must not operate the ALPHA
ALPHAALPHA
ALPHAMFD. Please understand, that
the instrument didn’t have any redundant function except the 9V back up battery
which allows a certain time of instrument use if normal battery fails.
