Aircraft Simulation

QPAC stands synonymous with the most realistic simulation of the Airbus Fly-by-wire and hydro-mechanical systems for the X-Plane world. The level of realism achieved made aerospace companies like Flight Data Services Ltd or universities like the Dresden University of Technology choose the QPAC A320 with its fly-by-wire technology as backbone for some of their projects. Flight data services Ltd uses a modified version of the QPAC A320 for X-Plane to replay Flight Data Recorder data from in-service aircraft to analyze and rate in-flight occurrences. At the Dresden University of Technology, the QPAC A320 is used as backbone for a research simulator at the Institute of Logistics and Aviation. In addition, DLR in Braunschweig, University Darmstadt, Flight Sim Service and Airbus Innovations are using our simulation within their projects.

In the scope of QPAC’s aircraft system engineering activities, QPAC has developed a multi-purpose simulation of the Airbus fly-by-wire aircraft family which provides a qualitatively accurate simulation of the following aircraft systems:

  • Electronic flight control (ATA27) and auto-flight (ATA22) system
  • Aircraft cabin ventilation, pressurization and temperature control (part of ATA21)
  • Aircraft electrical power distribution (ATA24)
  • Aircraft hydraulics generation and distribution (ATA29)
  • Aircraft fuel storage and distribution (ATA28)
  • Aircraft pneumatics system (ATA36)
  • Cockpit indications on PFD, EWD and SD (ATA31).

The simulation furthermore comprises simulation of the following aircraft systems:

  • Simplified system simulation for Bleed (ATA36) and Air Conditioning (ATA21)
  • Complete simulation of the hydraulics (ATA29). Control surface movements, as well as landing gear features depend correctly on the availability of the associated hydraulic circuits
  • Electrics system simulation (ATA24): Automatic and manual bus reconfiguration according to real-life aircraft logic. Cockpit instrumentation and lights only work if the associated bus-systems are powered. Same for the Flight Control Computers
  • Complete simulation of the Fuel System (ATA28) including the automatic sequencing of the fuel use in the different tanks, the possibility for fuel cross feeding etc.
  • Simulation of the Landing Gear System (ATA32) giving a more realistic auto-brake behavior and making gear features dependent on the availability of the respective control units and the hydraulic pressure
