Aircraft Communications Addressing and
Reporting system
The Aircraft Communications Addressing and Reporting system ( ACAR ) demonstrates
another typical use case that cannot be implemented without having a reliable real-time
processing system in place. These Aircraft communication systems use satellite commu-
nication ( SATCOM ), and as per the following figure, they gather voice and packet data
from all phases of flight in real time and are able to generate analytics and alerts on the data
in real time.
Let's take the example from the figure in the preceding case. A flight encounters some real
hazardous weather, say, electric Storms on a route, then that information is sent through
satellite links and voice or data gateways to the air controller, which in real time detects
and raises the alerts to deviate routes for all other flights passing through that area.
