Slide 3

State-of-the-Art

Current ATM communications systems in Europe will be completely overloaded within the next 15 years, even if

8,33 kHz program is extended

VDL Mode 2 is completely deployed (Link 2000+, Cascade)

For passenger communications (APC) a strong market demand on high-rate data transmissions is still expected

Covered mainly by satellite communications

“Re-use“ of satellite capacity for ATM seems possible if technical challenges (security, integrity, QoS) can be solved

Change of paradigms in aeronautical communications is expected

Less ATM voice, more ATM data link communication

Integration of ATM and APC into one framework

Slide 5

State-of-the-Art

Requirements from ACARE SRA 2020

Three times more aircraft traffic en-route

Three times increased airport capacity

Nine times improved security

Transparent ATM system

Actions currently undertaken

Europe (EC Projects): ANASTASIA, B-VHF, …

ICAO ACP activities

FCS and FCI jointly developed by FAA and Eurocontrol

Expectation: Several aeronautical communications system for different application areas

Missing: Overall approach, integrated network

Slide 6

The NEWSKY Approach

“Networking the Sky“ = Development of a global, heterogeneous communications network for aeronautical communications

Integration of different communications systems, i.e. ground-based ATM, satellite-based ATM, ATM within airports (A-SMGCS), and ATM between aircraft (ad-hoc network)

Integration of different applications and services – ranging from ATC/ATM over AOC and AAC to APC

Ensuring that safety critical applications and services are always served in time with the required Quality of Service (QoS)

Ensuring network security

Goal: Enable aircraft to be included in CDM and SWIM

Similar research in the U.S. on “network enabled operation”

NEWSKY – enabler for the flexible airborne infrastructure!?!
