Getting Started Introduction ACD-57 is a small multi-function control display intended for controlling ATC radar beacon systems (transponder, XPDR) and airborne VHF transceivers (COM). Furthermore the system is capable of determining and displaying a precise pressure altitude (altimeter). The system is connected to transponder and COM devices using standardized interfaces.
avionics 1. Getting Started Limitations and Safety Instructions Safety ACD-57 shall never distract from general practices of safe airmanship. Using ACD-57 may impose signi cant workload on the ight crew if not adequately familiar with ACD-57 and trained on its operation. In order to use ACD-57 e ectively, familiarization with the unit is essential.

avionics 1. Getting Started Light Sensor A sensor detecting ambient lighting conditions is placed on the left side of the concentric rotary knobs. User interface illumination, that is display backlight and softkey illumination, can be automatically adjusted using information from the light sensor. This function has to be activated by setting a con guration parameter during installation.
avionics 1. Getting Started Connected Devices Parameter Changes Whenever a parameter in an external system such as a COM or XPDR device is changed, ACD-57 sends a change request to the COM or XPDR device through a data interface. Information is only updated on the display screen of the ACD-57 if the change has been acknowledged and transferred back to ACD-57 by the COM or XPDR device.

COM Operation Introduction ACD-57 is capable of controlling a connected VHF transceiver (COM). ACD-57 can serve as primary means for control of a COM unit including COM unit setup, channel selection, and audio control. Multiple ACD-57 can be installed on one COM unit and control the COM unit simultaneously. This is especially used in large aircraft or aircraft with tandem seating con gurations.
avionics 2. COM Operation The display of station names in ACD-57 requires GPS position data from an external source that needs to be connected and con gured during installation. Furthermore a valid station database (microSD card) is required. If no GPS position data or no station database is present, the function is not available and station names are not shown.

Software and Station Database Updates Version Identi cation The software version can be reviewed in CONFIGURATION MENU DEVICE INFO. Software/Database Loading Software updates and the station database are loaded using the integrated microSD card slot and a microSD memory card. While the software is actually loaded onto the device, the station database remains on the microSD card.
Page 45
Using a Station Database To use a database, please carry out the following steps: 1. Purchase a valid station database le in the AIR Avionics License Store. Please visit http://www.air-avionics.com/license for details. 2. Load the station database le onto a microSD card.
Page 46
avionics 7. Software and Station Database Updates The station database and related functions are only available while the microSD card holding the station database le is inserted. If the microSD card is removed, the database and all related functions are unavailable. Loading Software to ACD-57 For details on loading new software onto ACD-57, please consult the ACD-57 Installation Manual [1].
Failures and Abnormal Operation ACD-57 features a range of built-in self test features that continuously monitor system state and the state of connected systems to detect failures. Failures The detection of a failure is always annunciated to the ight crew on the display. Depending on detected failure and failure severity, the system may seize to function or functionality may be limited.
