Computer Hardware, Software and Set-Up

Computers provide the 'grunt' to operate the software. 

I am not an expert on computers or their internals, however, I do have access to a number of individuals who do have a sound knowledge in this field.  Like anything in life, success is not always what you know, but learning to accept the knowledge of others and build upon this knowledge.

The simulation will use Flight Simulator 10 (FSX) and the avionics suite will be ProSim737 distributed by ProSim-AR.  Previously I was using Sim Avionics (Sim-A).

To run the simulator, I am using two computers linked in a network. The benefit of using two or more networked computers is the sharing of resources; accessory programs need not take valuable resources required for FSX to operate smoothly.  One computer operates FSX and the main ProSim737 module while the second computer hosts other necessary programs and the ProSim737 accessory modules. 

When the forward and aft overhead is implemented, a third computer will be added to the network.  This computer will be dedicated solely to the overhead panels.

Technology is not stagnant and as more powerful computers and other technology comes 'on-line' these improvements will be used.

I run the same operating system (currently Windows 7) across all computers as this makes networking much easier.  Furthermore, I use relatively powerful client computers as this ensures that multiple programs run flawlessly without RAM and memory problems.  This philosophy minimises the number of client  computers required.

Interface Cards & Equipment

A project of this magnitude cannot be developed without the use of interface cards.

Apart from the FDS-SYS4X System Interface card and the FDS IBL power distribution board, which are used to power the Main Instrument Panel (MIP), all the interface cards, relays, etc are accommodated in interface modules that sit forward of the simulator.

The FDS cards are located on the rear of the MIP.

This section provides information on the interface modules.

Project Architecture  

An unusual title that I am lead to understand is a visual document showing the architecture of the systems and how they integrate with each other, the main instrument panel, instruments, throttle, yokes, various interface cards and computers.

I favour the use of modular systems, rather than installing interface cards 'willy nilly' without any specific order.
