1.1 Introduction
This manual is intended to provide mechanical and electrical information for use in the
planning and design of an installation of the Air Control Display 57 (ACD-57) into an aircraft.
This manual is not a substitute for an approved airframe-specic maintenance manual,
installation design drawing, or complete installation data package. Attempting to install
equipment by reference to this manual alone and without rst planning or designing an
installation specic to your aircraft may compromise your safety and is not recommended.
The content of this manual assumes use by competent and qualied avionics engineering
personnel and/or avionics installation specialists using standard aviation maintenance
practices in accordance with relevant accepted practices. This manual is not intended for
use by individuals who do not possess the competencies and abilities set forth above. Refer
to section ‘‘Limitations’’, for additional information and other considerations.

Control of a VHF COM (e.g. channel tuning, volume control, control of specic features
like ‘‘say again’’).
•Control of a transponder (e.g. squawk, mode, ight ID, etc.).
•Station database
•Channel memory and history
•‘‘Nearest station’’ function
1.5.4 Limitations
1. Using the alticoder of ACD-57 is limited to 40,000ft (FL400).
2. Using the altimeter of ACD-57 is limited to 40,000ft (FL400).
3.
Use of the device is limited to class II aircraft (MRE, MTE and STE), which includes
class I aircraft (SRE), both with MTOW of 6000 pounds or less as per denition of
AC23.1309-1E.
4.
Use of ACD-57 as primary and only altitude measurement device of the aircraft is
excluded, if loss of functions or misleading information is assessed higher than Minor.
5.
The operator must verify that the installation meets the airspace requirements where
the ights are intended.
6.
The device does not provide static error correction. Therefore installation is limited
to aircraft where static error correction is not required.
1.5.5 Installation
Conditions and tests required for TSO approval of this article are minimum performance
standards. It is the responsibility of those installing this article either on or within a specic
type or class of aircraft to determine that the aircraft installation conditions are within the
TSO standards. TSO articles must have separate approval for installation in an aircraft. The
article may be installed only if performed under applicable airworthiness requirements.
To mitigate against the loss of communication, altimetry, ATC radar beacon functionality or
control thereof, installation of a second ACD-57 system may be required.
Please be aware that not all functions supported by ACD-57 may be supported by connected
COM and transponder devices. Carefully observe limitations and functions of connected
devices in order to assess system limitations that apply to your aircraft. Please consult the
ACD-57 ·Installation Manual ·rev. 2.0 ·2018/03/29 5
1. General Description
air avionics
section ‘‘COM and Transponder Compatibility Considerations’’ on page 18 for details on
supported connected COM an transponder devices.
Certain functionality is subject to a software licensing model. In order to unlock these
functions, a software license has to be purchased and a code has to be entered in the
conguration menu. Please consult the section ‘‘License Management’’ on page 26 for
details.
Unlocking of required functionality has to be done during installation and before the
device is used.
1.5.6 Station Database
ACD-57 is capable of reading a COM station database from mass storage devices (microSD
card).
The station database may contain errors
The ight crew is ultimately responsibly for channel selection. The station database is
used for reference only.
We request that the ight crew report any observed discrepancies related to database information.
These discrepancies could come in the form of an incorrect channel, incorrectly identied station, or
any other displayed item used for communication in the air or on the ground.
1.6 Liability
IN NO EVENT WILL AIR AVIONICS BE LIABLE FOR ANY INCIDENTAL, SPECIAL, INDIRECT OR
CONSEQUENTIAL DAMAGES, WHETHER RESULTING FROM THE USE, MISUSE OR INABILITY
TO USE THE PRODUCT OR FROM DEFECTS IN THE PRODUCT.
1.7 Unpacking and Inspecting Equipment
Before installation into an aircraft, the equipment should be visually inspected for shipping
damages and completeness. If the unit is damaged, notify the carrier. Do not return the
unit to AIR Avionics before the carrier has authorized a claim.
The following parts are normally included with ACD-57:

Figure 2.3.: Generic CANaerospace data bus wiring recommendation between bus nodes
The maximum recommended cable length between data bus nodes is 10m.
The data bus interface (CANaerospace) consists of two data wires. The dierential high-
speed signal requires impedance controlled shielded cables or at least twisted pair shielded
cables.
The data bus interface is a dierential high speed signal. The data bus interface requires
termination resistors to be installed on each end of the bus (120 Ohm).
On each connector, pin 12 is internally connected to the CANHI pin via a built-in 120 Ohm
resistor. To terminate the bus, pin 12 can simply be connected to pin 7. In this case, external
termination resistors are not required and shall not be installed. This is the recommended
termination method.

protocol. For a detailed description
of supported datasets, please contact AIR Avionics support.
2.2.2 Serial Data Interface
ACD-57is capable ofinterfacingwith other aviation instrumentsby sendingand/or receiving
serial data on its serial ports.

The serial outputs conform to RS-232C (EIA Standard) with a positive and negative output
voltage of at least 5V when driving a standard RS-232 load.
The serial data interface (RS-232) consists of one or two data transfer wires and a ground
connection. As shown in the example below, there shall always be a direct ground
connection between all RS-232 clients.
It is not sucient that power supply ground in both devices is connected to aircraft
ground, an additional direct ground connection is mandatory.
The use of a twisted pair shielded cable, for example MIL-C-27500-22TG 2T14
2
, is highly
recommended. With this cable both data wires and the GND reference can be connected
using a single cable.
