Simulation - Background

• Produce large scale simulations for Boeing
  airplanes
• 707, 727, 737, 747, 757, 767, 777
• 500K lines of FORTRAN per airplane model with a
  staff of 100 engineers, the 777 has over 1M
  lines of code
• Modeling of the following types
• Aerodynamic flight characteristics
• Avionics flight controls units
• Propulsion, mechanical electrical systems
• Simulations execute on high-end HP 9000 servers
  Concurrent NightHawk real-time computers
