Simulation - BackgroundSimulation - 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

7

Simulation - UsageSimulation - Usage

Interactive Use (No Airplane H/W)– Engineering Studies– Simulation Development– Simulator data documents

Engineering Flight Deck Simulators

– Engineering studies

– Pilot evaluation

– Accident/incident investigation

Avionics/Flight Control Test Benches– Airplane system testing
