WHY CHANGE FROM PCM? CASE STUDY OF THE AIRBUS A380 ETHERNET BASED DATA ACQUISITION NETWORK

ITC/USA 2005 Conference Proceedings / The Forty-First Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2005 / Riviera Hotel & Convention Center, Las Vegas, Nevada / The adaptation of ubiquitous Ethernet technology to airborne FTI systems is a relatively recent
development, offering multiple advantages to FTI applications, including a high data throughput
and ability to integrate COTS equipment with ease.
For large-scale FTI applications – such as on the Airbus A380 - the use of traditional PCM based
data acquisition systems results in enormously complex system architectures, with difficulties in
system design, implementation, commissioning, test and maintenance. However, on the A380,
the use of the Ethernet-based, IENA protocol alleviated these problems, in addition to offering
several additional advantages.
This paper explores the theoretical and practical implications of using Ethernet-based data
acquisition in an FTI application, with direct comparison to an equivalent PCM based system.
