1.3 Device Overview
The traffic display TM250 by Funkwerk Avionics GmbH is aimed at supporting air space surveillance for General Aviation. It integrates Mode S, ADS-B, and FLARM ®-Detection in one single device for cockpit installation.
ADS-B, Mode S and Mode AC ADS-B (Automatic Dependent Surveillance – Broadcast) means that
airplanes whose Mode S transponder is coupled with a GPS receiver emit their position data on the frequency 1090 MHz. This data can be received by all airspace users in a vicinity of up to approx. 150 NM. These ADS-B transmissions from other airplanes are decoded by the built-in Mode S receiver in the TM250. The display of the TM250 indicates the relative position of these airplanes as well as their vertical movement direction. This allows a quick assessment of the traffic situation.
Today, the majority of Air Transport airplanes are equipped with ADS-B capable systems. Because General Aviation still has a relatively low degree of ADS-B equipage, airplanes whose transponders do not send out ADS-B signals are also detected by the TM250. This is achieved through evaluation of the field strength of the Mode S and Mode AC signals. In this case, the proximity of such airplanes is signalled by the TM250 graphically and acoustically. However, a representation of direction or position of these airplanes is not possible.
The TM250 includes a built-in GPS receiver and can transmit its position data via an additional serial interface to an ADS-B capable Mode S transponder (such as the TRT800A/H). Such an installation forms a complete ADS-B system that can receive and transmit position data through ADS-B and contributes therefore actively to flight safety.
FLARM® Nowadays, numerous glider aircraft are equipped with so-called FLARM®
systems for collision avoidance. Via a serial interface, an external FLARM® receiver can be connected to the TM250 which then allows indicating the position and movement direction of these airplanes on the display of the TM250.

), in order to avoid
This does not impact the display of
In case an external FLARM® is connected, the FLARM® will automatically be disabled (see 2.4.2 permanent alerting. FLARM® targets. FLARM® targets will still be displayed.
If the aircraft does not carry such a FLARM® receiver connected to the TM250, other gliders nearby that have a FLARM® transmitter can still being detected and indicated on the TM250 graphically and acoustically. This is achieved through a raw, non-directional detection of the signal strength of a nearby FLARM® transmitter inside the TM250. In this case, however, it is not possible to indicate the direction, distance, altitude, or position of such targets. Also, no transmission to other gliders occurs.
For traffic display and warning, four different types of targets are distinguished depending on the respective equipment of these aircraft.
1. FLARM® targets Aircraft, particularly gliders, with a FLARM® system: As long as no
external FLARM® receiver is connected to the TM250, the recognition of the FLARM® equipped airplanes is based merely on the detection of the signals, and will be shown in the counter, but not on the “map”.
Due to their low radio transmission power, FLARM® targets can only be detected in smaller distances than the other target types.
2. Mode S targets Aircraft with a Mode S transponder without ADS-B "out" function (not
"extended squitter" capable): The Mode S Transponder sends out the ICAO 24bit address that allows identifying the transmitter. A rough estimate of distance and approach rate of each transponder is determined by measuring the field strength of these transmissions.
3. Mode AC targets Aircraft with non-Mode-S-capable (older) transponder: The transponder-
transmissions contain either the altitude (Mode C) or the Squawk (Mode A). It is technically not possible to always distinguish between these two transmissions – for safety reasons, in these cases the information is always interpreted as altitude, what may lead to unnecessary warnings. As additionally the AC transmissions do not contain the 24bit address of the Mode S signal, it is not impossible, that one and the same aircraft, due to transmitting both Mode S and

2.4.1 Audio
In addition to the visual warnings audio alerts can also be raised. The following settings for when and how audio alerts will be raised are offered:
once ........... For each traffic object, an audio alert is raised only once
when it is recognized as a threat
repeat ......... The audio alert continues as long as the target poses a
threat or the user confirms (and thus silences) the alarm with the
or
key. Any alert needs to be confirmed separately. Depending on the threat level the audio alerts will be repeated every 4 seconds for the approach alarm, every 2 seconds for a potential collision threat and once per second for an active collision threat.

Conditions for raising an audio alert differ depending on the type of traffic (FLARM®, Mode S, ADS-B). The following table shows the different conditions:
FLARM
Warning tone sounds once as soon as a FLARM® signal is received.
As long as the alarm stays active no further warning tone will sound.
A warning tone sounds as soon as the field strength of a Mode S exceeds the selected threshold.
Because a Mode S target can be identified by its 24 bit ICAO­address, the warning is only raised again when the target poses a threat again.
As for Mode S As for Mode S
Each time an ADS-B object enters one of three protection zones, (horizontally 6 NM, 3 NM, 1.5 NM; vertically 1200 ft, 600 ft, 300 ft) a single audio alert is raised.
The warning tone sounds repeatedly as long as the alarm is active or until it is confirmed by the user
As long as the measured field strength of a target exceeds the thresholds, the warning tone sounds repeatedly. The warning tone can be confirmed (silenced) by the user.
While an ADS-B object is within the protection zones, the warning tone sounds repeatedly until the target leaves the zone or the alert is confirmed by the user.
Acoustic warning hints are made of different sound schemes in order to specify the kind of threat in more detail:

In case that at least one FLARM® equipped aircraft is too close to the own aircraft, the symbol “f” together with the number of targets will be displayed at the upper right display corner. This warning is based on the detection of the respective signals as transmitted by such aircraft. An alert stays active for at least 10 seconds, even if the target is detected only for a short period of time.

and
If no barometric altitude is available, e.g. because the own Mode S transponder is not ADS-B capable, the altitude determined by the GPS receiver is used for comparison. In the traffic view this is indicated by the missing flight level information ("No FL" in the left lower corner). In this case, relative altitude cannot be computed correctly (comparison of GPS with Barometric altitude). Therefore, only the absolute flight level of the traffic objects, marked by a preceding "FL", is indicated in this case.
2.4.7 Traffic Transmit - Tfc Tx
With the setting Tfc Tx, the output format can be set for additional connected display devices (moving map displays). See Section 2.7. Here are two supported formats:
default Use the setting "default" for devices which support the text-
based protocol (pseudo FLARM®). at 19200 baud These include the SkyView® devices of DYNON and FlyMap® displays of Stauff Systec.
others With "others" ADS-B traffic data can be sent to any device
using a binary protocol at 9600 baud. In contrast to the "default" mode only ADS-B traffic is transmitted, but no Flarm® or Mode A/C and S.

2.5 ICAO Configuration Page
With the key the configuration view for ICAO can be selected. In order that ADS-B signals of the own Mode S transponder will not be
misinterpreted as one of another traffic object, the TM250 must be initialized before first use. Based on the transponder signals, the TM250 determines which ICAO 24-bit address is assigned to the own aircraft.
During this initialization, the currently received ADS-B messages (position, height, ICAO 24-bit address) are compared with the own GPS position. If an ADS-B signal is received with the same position, this is interpreted as the own one and the ICAO 24-bit address is adopted. The corresponding barometric altitude will be used for comparison with the ADS-B transmission from other traffic objects and thus serves to determine the relative altitude (see 2.3.2).
If the own Mode S transponder is not ADS-B capable, the signal with the greatest field strength is interpreted as the own one. If an own barometric altitude cannot be determined, the absolute height in flight levels (FL) is used for the representation of transport objects instead of relative height values (see 2.3.2).
The described initialization is done under the menu item ICAO:

such as external and own position, the detected 24-bit address (eg 3bcdef) and a progress bar will be
displayed. failed no match found TRX error no ADS-B reception GPS error no GPS position available Whether the initialization was successful, can be determined during the
operation in the status display (see above) or on the information page (2.6). In the event of a failed initialization there is no valid ICAO 24-bit address displayed and setting of the own ICAO address must be made by yourself on the information page (2.6).
If during multiple automatic searches no valid ICAO address is obtained, you try to change the location of the aircraft. For example, already a nearby hangar or tarmac may prevent the detection.
In flight, the ICAO address must be detected automatically without problems, otherwise the own barometric altitude cannot be determined. Do not make those settings by yourself, but leave this to the copilot.
If the automatic search is not successful in flight, check the settings in the transponder. The transponder must be able to process the TM250 NMEA data at 4800 baud.
Check the automatically determined according to ICAO address on their own!

3.3 Mounting
• In cooperation with aircraft maintenance, a suitable location and installation method must be determined. All cables can be installed by the maintenance personnel. Suitable cable kits are available from Funkwerk Avionics.
• Avoid installing close to heat sources. Sufficient aerial circulation is necessary.
• When installing the cables and connecting plugs leave enough space for each.
• Sharp bending and routing of wires close to control cables should be avoided.
• The cables must be long enough so that plugs are accessible for repair.
• The cable harness that leads to the device connector must be placed so that condensation water cannot leak into the plug.
• For installation tips and drawings see chapter 3.5.2 "installation tips".
• Inside antenna:
o While installing an antenna inside the cockpit, take care that
the pilot’s outside view is not obstructed
o The antenna should be mounted in such a way that the
edges of the antenna are vertically directed
• Outside antenna:
o The FLARM® antenna shall be installed as far as possible
from the transponder antenna to avoid that the own transponder signals block the reception of other signals.
o In most cases, the transponder antenna is installed on the
bottom of the aircraft; it is thus recommended to install the FLARM® antenna on top of the fuselage.

please make sure that the transponder used is capable to
A signals at the respective
interface. To achieve this, it might be necessary to change
ol NMEA / 4800
Antennas installed inside the cockpit should still allow a good outside view.
Both antenna types shall be installed vertically and with a large distance to the transponder antenna.
3.4.3 USB
Via the USB socket and the USB cable supplied together with the TM250, ADS-B DF17/18 reports that are received by the TM250 can be provided to an external PC in binary format. The USB socket also allows updating the software (see 2.8).
3.4.4 Power / RS-232
Through this 9-pole D-Sub socket (male) the TM250 is supplied with power.
In addition, this socket provides the RS-232 signals to connect a TRT800 (A/H) transponder.. With this connection the transponder obtains the NMEA signals from the internal GPS receiver of the TM250 for the transmission of ADS-B reports.
In order to assure the proper transmission of ADS­process respective NME the settings of the transponder (protoc
Baud).
Another RS-232 interface allows connecting an external FLARM® receiver as well as a display system. (When the USB socket is used, however, this interface is deactivated).
A suitable connection cable is supplied together with the TM250.

4.3 Threat Classifications – Zone Division
Basically, the collision warning is based on the comparison of the own position with the location of surrounding traffic. With ADS-B traffic, this is done using the respective position reports. For Mode S traffic (not ADS-B capable), the field strength is measured. The proximity of FLARM® traffic is detected whenever a signal is received (which suffices as the maximum range of FLARM® reception is relatively small).
The priority of a collision warning is determined on the basis of three predefined zones. These are defined in each case by a distance radius as well as by an altitude range around own position.
34Document No.: 03.310.010.71e / Revision: 2.10
TM250 / P/N 250TM-(xxx)-(xxx)
Zone 1: If a traffic item closes in to less than 6 NM with an altitude
difference (relative altitude) of less than 1200 ft, the first zone is injured. In the traffic display the traffic symbol changes to a
filled diamond . This proximity alert does not yet indicate a threat.
Zone 2: If a traffic item closes in to less than 3 NM with an altitude
difference (relative altitude) of less than 600 ft, the second zone is injured. In the traffic display the traffic symbol
changes into a yellow full circle . This classifies the target as a potential threat.
Zone 3: If a traffic item is less than 1.5 NM away with an altitude
difference (relative altitude) of less than 300 ft, the third and most critical zone is injured. In the traffic display the traffic
symbol changes into a red full square . The target is thus classified as an imminent threat that requires immediate action.
Besides the spatial boundaries of these zones, the approach rate is also taken into account.
An alarm equal to the zone 2 violation will be raised if an encounter is forecasted in less than 70 seconds. This will happen regardless of the zone in which the intruder is. (obsolete if target is already inside zone 3).
An alarm equal to the zone 3 violation will be raised if an encounter is forecasted in less than 20 seconds. This happens regardless of the zone in which the intruder is..
For Mode S traffic the measured field strength will be compared to pre­defined threshold values, as well as the flight level (when transmitted). Mode S traffic is using only two zones wherein the zones 1 and 2 are combined into one.
Regarding FLARM®, the range of reception is comparable to the zone 2 boundaries.
