Avionics server platforms for connected aircraft computing

Onboard computing platforms are becoming central to aircraft digitalisation strategies, particularly as airlines expand in-flight entertainment and connectivity (IFE&C) and data-driven operational services. In this context, Kontron introduced the Ace Flight™ 4609 avionics server for next-generation connected aircraft applications.

Computing platforms for in-flight digital services
The Ace Flight™ 4609 was developed to support bandwidth-intensive passenger services and airline digital applications, including onboard media distribution, connectivity management and operational data services. These systems form part of the broader connected aircraft ecosystem, where onboard computing supports both passenger-facing and operational applications.

Built on Intel^® processor technology, the platform provides onboard computing capacity intended to support simultaneous applications such as streaming services, cabin connectivity management and airline operational software.

Hardware architecture focused on scalability and integration
The avionics server integrates high-speed networking interfaces, avionics connectivity options and removable storage designed to support flexible deployment scenarios. This architecture allows airlines and connectivity providers to deploy multiple applications while maintaining upgrade paths for future software and hardware requirements.

The system was designed to support integration into existing aircraft digital infrastructure while accommodating future expansion requirements associated with increasing onboard data traffic.

Performance improvements over the previous platform generation
Compared with the previous Ace Flight™ 4608 platform, which was based on an 8-core Intel^® Xeon^® processor and DDR4 memory architecture, the Ace Flight™ 4609 incorporates a 14-core Intel^® i7 Raptor Lake processor with 64 GB DDR5 memory.

The updated platform also integrates 5G and LTE connectivity capabilities intended to support higher data transfer rates and improved connectivity management for connected aircraft environments. These hardware changes increase available processing capacity and storage potential for applications requiring higher compute performance.

Design considerations for aviation environments
The Ace Flight™ 4609 was developed to meet environmental and reliability requirements associated with avionics equipment while delivering computing performance comparable to compact data centre platforms. The hardware is designed for installation in aircraft environments where vibration resistance, thermal stability and system reliability are key design requirements.

The platform has entered production as part of Kontron’s avionics computing portfolio, supporting in-flight connectivity and digital aircraft infrastructure.
