4 Overview of Aeronautical Safety Services
4.1 General
The Aeronautical Safety Service provides the following safety services simultaneously via a single channel unit on an
aircraft to Class 6, Class 7 and Class 4 terminals:
• ACARS
• Prioritized IP data
• Voice (two channels)
The Aeronautical Safety Service is an application of the Family SL platform. ACARS and voice gateways are
introduced into the Airborne Earth Station (AES) and the peer gateways are introduced in the ground.
