Modern Avionics Architectures

Outline

This tutorial is an updated version of Cary Spitzer’s long-running course of the same name. Architectures from various civil and military aircraft are examined with comparisons of hardware and avionics functions of each discussed in detail. The tutorial presents key architecture and design challenges for legacy as well as new aircraft. These architectures have been carefully chosen to cover the following: 

  • Broad spectrum of aircraft types, military and civilian
  • Federated and integrated designs with emphasis on modern commercial and military aircraft
  • Line Replaceable Unit (LRU) vis-à-vis modular packaging 
  • Impact of the Modular Open Systems Approach (MOSA) on architecture 
  • Range of non-essential to flight critical applications and the impact on future designs

Presenter Bio

Timothy Etherington graduated from North Dakota State University with a Master of Science in Electrical Engineering in 1987. Tim is a Rockwell Collins Technical Fellow currently assigned to NASA Langley Research Center in Hampton Virginia. Mr. Etherington has worked at Rockwell Collins for over thirty years with extensive experience in military and commercial flight deck design and applied human factors. He helped design the flight decks for the Canadair Regional Jet and other business and regional primary flight display systems. He led the perspective, synthetic and enhanced flight deck research at Rockwell Collins including the flight-testing completed with NASA Langley and Air Force Research labs. He holds an FAA Airline Transport Pilot certificate with a Citation Type Rating and holds commercial fixed wing and private pilot rotorcraft ratings. Mr. Etherington is co-chair for RTCA SC-213 working on standards for enhanced and synthetic vision systems.
