Applications of embedded systems in aerospace

  Embedded systems are used in nearly every facet of modern aerospace systems. This includes:
  
  
  

  • Instrumentation
  • Control systems
  • Avionics (control surfaces)
  • Communications
  • Navigation
  • Automatic pilot and landing
  • Entertainment systems
  • Network connectivity
  • Climate control
  • Personal comfort (seats, etc.)

  
  Flight-critical systems must meet stringent reliability standards, such as DO-178B reliability standards for aerospace and defense embedded software. These standards mandate specific development and testing methodologies, which must be independently verified/certified for use.
  
  Embedded aerospace software is usually written to be highly deterministic, in order to improve predictability in the system. This usually requires 'sharp' real-time constraints in the software, and promotes the use of either very simple, predictable code, or the use of an approved real-time operating system.
