INTRODUCTION
Applicable to:
The Aircraft Communication Addressing and Reporting System (ACARS) allows direct exchange of
data between aircraft and airline ground computer through the VHF 3.
Aircraft to ground messages (downlink) comprise operational, maintenance, monitoring, performance
and cabin data.
Ground to aircraft messages (uplink) contain crew information (wind for example) or might request for
transmission of data which are sent automatically or by crew action.
Automatic downlink of reports is carried out by ACARS Management Unit (MU), which is
programmed according to airline needs (Buyer Furnishing Equipment).
Due to the highly customized programming, the ACARS functions may vary for different airlines and
therefore are not described in detail.
SYSTEM ARCHITECTURE
Applicable to:
The ACARS system consists of a Management Unit (MU) connected to the following elements:
