5 Introduction
The echoUAT is a remotely mounted ADS-B transceiver that incorporates a dual-link (1090 MHz and 978 MHz) receiver and 978 MHz UAT Class B1S transmitter. An internal power transcoder detects altitude, ident and squawk codes from older-style Mode C or Mode S transponders by decoding the replies via the aircraft electrical system. No additional wiring to the transponder is required. The echoUAT has integrated Wi-Fi support to interface with most EFB applications, and integrates with a wide variety of existing EFIS systems. For use with either the SKYFYX GPS source or with an existing rule compliant GPS source.
It is designed to meet the performance requirements of TSO-C154c, and is compliant with FAR 91.225 and FAR 91.227 for operation in the National Airspace System.
! The system is for use in Experimental and LSA aircraft only.
5.1 Features

7.6 Cooling Requirements
echoUAT is designed to meet all applicable TSO requirements without forced-air cooling.
Attention should, however, be given to the incorporation of cooling provisions to limit the maximum operating temperature if the echoUAT is installed in close proximity to other avionics. The reliability of equipment operating in close proximity in an avionics bay can be degraded if adequate cooling is not provided.

15 UAV-1001006-001 ECCN 7A994

7.7 Wiring Considerations

The echoUAT was designed and tested using unshielded, untwisted wiring. There may, however, be technical benefits of improved electromagnetic emissions and susceptibility to and from the transponder system. The use of twisted wire can reduce interference and break-through on adjacent audio wiring if it is not possible to route them separately.

The distance between the echoUAT and the power source is limited by the impedance of the wire between them. The echoUAT is powered directly from aircraft power, and, therefore, the acceptable voltage drop in the power line is what limits the distance.

A 1A circuit breaker should be used between the echoUAT and the power source. A 3A gang circuit breaker can be used when echoUAT and SkyFYX are combined on the same circuit.

The echoUAT requires an impedance of less than 0.5ohm in the power line for satisfactory operation. The following table provides guidance for a typical aircraft hook-up wire. Note that different brands may vary � please check your supplier for more details.

Gauge 20 AWG 22 AWG 24 AWG

ohm/km 35 64 99

Length for 0.5ohm 14.2m 7.8m 5.0m

An alternative to a harness built from individual wires, particularly for a long cable run, is to use a multi-core cable. Aviation grade cables with 6 or more cores are often more expensive than individual wires, and, therefore, are not generally a good choice. For aircraft where those situations do not apply, an attractive alternative solution may be to use 3 or 4 pair data cable.
Please note that not all data cable is suitable for this application. Cables with solid cores should not be used. Cables should be selected based on the wear characteristics of their insulation material, including temperature rating, resistance to solvents and oils, and flammability. Most inexpensive commercial data cables have poor flammability properties.
16 UAV-1001006-001 ECCN 7A994

7.8 Antenna Installation
7.8.1 Antenna The antenna should be installed according to the manufacturer's instructions.
The following considerations should be taken into account when determining an acceptable location for the antenna.
� The antenna should be well removed from any projections, the engine(s) and propeller(s). It should also be well removed from landing gear doors, access doors or other openings which will break the ground plane for the antenna.
� The antenna should be mounted on the bottom surface of the aircraft and in a vertical position when the aircraft is in level flight.
� Avoid mounting the antenna within 1 meter of an existing transponder, ADF sense antenna or any COMM antenna and 2 meters from the DME antenna.
� Where practical, plan the antenna location to keep the cable lengths as short as possible and avoid sharp bends in the cable to minimize the VSWR or signal loss.
Electrical connection to the antenna should be protected to avoid loss of efficiency due to exposure to liquids and moisture. All antenna feeders shall be installed in such a way to minimize RF energy radiated inside the aircraft.
When a conventional aircraft monopole antenna is used, it relies on a ground plane for correct behavior. For ideal performance, the ground plane should be large relative to the wavelength of the transmission, which is 275mm. In a metal, skinned aircraft this is usually easily accomplished, but is more difficult in a composite or fabric skinned aircraft. In these cases, a metallic ground plane should be fabricated and fitted under the antenna.
The ground plane should be as large as you can sensibly make it. Because it is a function of the wavelength of the transmission, the smallest practical ground plane for a transponder is a approx. 120mm per side. As the size increases, the performance improves, until the ground plane is approx.
17 UAV-1001006-001 ECCN 7A994

700mm on each side. Anything much larger than that size is unlikely to result in significant further improvement. The thickness of the material used to construct the ground plane is not critical, providing it is sufficiently conductive. A variety of proprietary mesh and grid solutions are available. Heavyweight aluminum foil meets the technical requirement, but obviously needs to be properly supported. 7.8.2 Antenna Cable The echoUAT is designed to meet Class B1S. Excessive loss in the cable and connectors will degrade both transmitter output power and receiver sensitivity. An acceptable cable:
� has less than 1.5dB loss for the run length needed, � has a characteristic impedance of 50ohms, � has double braid screens or has foil and braid screen. Once the cable run length is known, a cable type with low enough loss per meter that meets the above requirements can be chosen. Longer runs require lower loss cable. The following table is a guide to the maximum usable lengths of some common cable types. Actual cable loss varies between manufacturers. There are many variants, and the table is based on typical data. Use it as a guide only and refer to the manufacturer's data sheet for your specific chosen cable for accurate values.

When routing the cable:
� Route the cable away from any significant heat sources � Route the cable wiring away from potential interference sources such
as ignition wiring, 400Hz generators, fluorescent lighting and electric motors � Allow a minimum separation of 300mm from an ADF antenna cable � Keep the cable run as short as possible � Avoid routing the cable around tight bends � Avoid kinking the cable, even temporarily, during installation � Secure the cable so that it cannot interfere with other systems

8 Installation Setup
Download the "uAvionix Echo Installer" app from the IOS App store or Google Play. Note: Do not use the "uAvionix Ping Installer" app by mistake.
8.1.1 Connecting to the echoUAT via Wi-Fi To connect to the echoUAT, join a device to the wireless network named "Echo-XXXX" using the procedure for your device. iOS is shown below: 1. Go to Settings > Wi-Fi, and make sure that Wi-Fi is turned on. 2. Tap the SSID Ping-XXXX where XXXX is a random string. i.e. Ping6A8E. 3. No WPA Password is required.* *Some early software builds require a WPA password... Enter uavionix as the WPA password for the secure Wi-Fi network, then tap join. Note: The No Internet Connection message is normal when iOS is connected to echoUAT.
20 UAV-1001006-001 ECCN 7A994

4. Launch the Echo App on your tablet or smartphone.
Make sure "EchoUAT is the Selected Device Type.
8.2 Configuration
The configuration section will set the following parameters: � Control � ICAO Number � Call Sign � Flight Plan ID � CSID Logic � Anonymous Mode � Emitter Category � VFR Code � ADS-B In Capability � Vso � Aircraft Length and Width � GPS Antenna Offset
8.2.1 Control Select the desired control type. This setting configures the echoUAT for Transmit, Receive or Standby.
� UAT TX Enabled: Enables both transmit and receive functions. This is the recommended mode for 2020 compliance..
21 UAV-1001006-001 ECCN 7A994

� Receive Only: Disables transmission but continues to receive and provide ADS-B data to a GDL90 compatible display or application.
� Standby: Disables both the transmit and receive functions. GDL90 position data (GPS) is still available from the device.
8.2.2 Aircraft Address Programming The ICAO address is a 24-bit number issued to the aircraft by the registration authority of the aircraft. These addresses are usually written as a 6-digit hexadecimal number, although you may also encounter one written as an 8-digit octal number. The echoUAT understands the hexadecimal format, so you must first convert an octal number to hexadecimal before entering.
Tip: By using the N-Number Look Up function on https://www.faa.gov, locate and use the "Mode S Code (base 16 / hex)" value.
8.2.3 Call Sign The CALL SIGN can be up to an 8 digit code that corresponds to the tail number of the aircraft. (0-9, A-F).
Note: This is typically your aircraft N-number, unless otherwise advised by the FAA or ATC.
8.2.4 Flight-plan ID Flight Plan ID, if provided, is used in accordance with product specific transmission requirements. CSID Logic is applied to determine if the Flight Plan ID is transmitted.
Flight Plan IDs are intended to contain Mode 3/A (12-bit) or expanded (18bit) codes, and shall only contain between 4 and 6 characters, consisting of ASCII encoded values for digits 0-7.
Tip: Generally, this field will be left blank, unless otherwise advised by the controlling authority.
8.2.5 CSID Logic Specifies Call Sign Identification (CSID) transmission behavior. Always set CSID Logic to "Enabled" for 91.227 Compliance. A setting of "Disabled" will result in a failure to generate an ADS-B Performance report.
Description
22 UAV-1001006-001 ECCN 7A994

Disabled, CSID always set to 1 (Callsign) Enabled, CSID alternates between 1 (Callsign) and 0 (Flight Plan ID)
Note: CSID should always be "Enabled", unless there is a special circumstance requiring it be set to "Disabled".

8.2.6 Anonymous Mode When checked, this enables the EchoUAT to transmit a self-assigned ICAO and sets the Call Sign to a random string such as "PINGFDF8" when the squawk code matches the defined VFR squawk code. Note that anonymous mode is only active if a flight plan has not been filed (per AC 20-165).

Tip: Anonymous Mode must be "DISABLED" for the FAA Performance test flight in order for the FAA to register the flight to the aircraft's Call Sign.

8.2.7 Emitter Category To assist ATC tracking of aircraft, an aircraft category can be transmitted. Select the aircraft category that most closely matches the aircraft.

Emitter Category

Light Airplane

Rotorcraft

Small Airplane

Glider / Sailplane

Large Airplane

8.2.8 VFR Squawk code This sets the default VFR squawk code. E.g. 1200 for the USA.
8.2.9 ADSB-In Capability Sets the ADS-B in equipment capability reporting. EchoUAT is capable of receiving on frequencies. The recommended setting is "Both UAT and 1090".
23 UAV-1001006-001 ECCN 7A994

ADS-B In capability None UAT 1090 Both UAT and 1090
8.2.10 VSO (knots) This parameter allows the echoUAT to automatically switch between airborne and ground modes. Enter the VSO value for your aircraft. Setting VSO to 0 passes control of the Air/Ground state to the EFIS.
Airspeed (in kts) that the aircraft typically flies after take-off. 0 � 999 knots
Tip: If in doubt, you can set this to your maximum taxi speed. EchoUAT uses ground speed and does not account for headwind or tailwinds, that might affect the Air/Ground state.

8.2.11 Aircraft Length and Width in Meters When on the ground, ADS-B transmits encoded aircraft size information which is used by ATC to identify taxiing routes and potential conflicts. Enter the length and width (wingspan) fields and the appropriate size codes will be calculated for transmission.

Aircraft Length in Meters
L 15 15 < L 25 25 < L 35 35 < L 45 45 < L 55 55 < L 65 65 < L 75 75 < L 85 L > 85

Aircraft Width (wing span) in Meters
W 72.5 72.5 < W 80

24 UAV-1001006-001 ECCN 7A994

8.2.12 GPS Antenna Offset The GPS antenna offset is used in conjunction with the length and width to manage taxiway conflicts. A typical GPS does not report the geographic position of the center of the aircraft, or even the tip of the nose of the aircraft; instead, it usually reports the location of the actual GPS antenna (not the GPS receiver). In normal flight operation, this distinction is of no importance at all, but if ADS-B is used to manage taxiway conflicts, a significant offset in antenna position could mean the aircraft footprint is not in the same place as the ADS-B reported position. Although the GPS Antenna Offset is primarily intended for position correction on large transport aircraft, General Aviation aircraft can also have a significant offset. For example, if the aircraft has a long tail boom and the GPS antenna is on top of the tail, the GPS position could be 4 meters or more from the nose of the aircraft.

GPS Antenna Lateral Offset from roll axis (Meters)
0 Left 2 Left 4 Right 2 Right 4 Right 6

GPS Antenna Longitudinal Offset from aircraft nose (Meters)
