valuable sources of information. However, while research will often locate a lot of information, sometimes it is a minor detail that is needed. For example, how wide the center pedestal is, how large it should be, or its relative placement in the pit. Where the information is not in the public domain, more subtle techniques have been developed to obtain the information. For example, pixel counting from a digital photo of the aircraft. By counting the pixels in an item of known size, for example, a standard cockpit instrument, a scale can be established. This can then be used to estimate the size of unknown elements in the panel. Accuracy will vary depending on the quality of the photo located, the angle the shot was taken from, etc. However, this can give a good guideline on dimensions in situations where there may be no other source of information.
163:" displays it has become easier to create highly realistic panels. The displays on these panels can be driven by multi-head graphics cards, or networked PCs running dedicated software that can read from the simulator spreading the processing load. Interfaces for switches, knobs, and other elements needed can be purchased commercially or created by dismantling existing hardware such as keyboards or joysticks. Feedback from the PC to the panel, for example to light warning lamps or move a real instrument is more complex and normally completed through a commercial expansion board.

of the scale is to build an exact 1:1 replica of the real cockpit, using real panels or even a complete cockpit from the chosen plane. All cockpit builds will be somewhere between these two concepts, and even highly accurate replica pits will often make some concessions, if only due to limitations of the simulation software driving them.

With a GT style seating, the bum is placed higher than the pedals (for example the seating surface can be placed 10 cm to 30 cm higher than the bottom of the pedals), which facilitates for a more comfortable and effective driving posture with between 90 and 120 degrees of bend in the elbows

Commercial airliner pits offer a greater challenge to builders as there are more systems to model such as the autopilot, CDU/FMS, engine management, etc. Even the throttle quadrant is a complex piece of engineering compared to the simply replicated push/pull throttle used in the GA Cessna. However, a

For replica pits, the choice of aircraft will be key. With the growth of home cockpits, there are a number of companies who sell complete kits for common aircraft, and the details of current Airbus and Boeing aircraft panels are fairly easy to obtain.

Recognizing this market, a number of suppliers provide ready-to-go desktop simulation products. Radio stacks, instruments, yokes, pedals, throttle quadrants, and seats are readily available from pilot shops. This allows a highly realistic GA cockpit to be put together in a matter of minutes.

Recently, the increased power of home PCs and improvements in graphics and simulation technology has opened up further opportunities to use a PC as a training aid.

A way to avoid a lot of the pitfalls is to not replicate a specific aircraft, simply a class of aircraft. Thus creating a generic GA, airliner, or military cockpit, which while it will not have every button or switch of the real aircraft, will have all the key elements for simulation. The other end

The level of functionality will also vary within the 'pit'. Very realistic-looking pits may have nonfunctioning instruments, simply in place to complete the 'feel' of the cockpit. At the top end of realism would be individual real instruments, either modified from actual aircraft components or

Many high-quality frames are made of aluminum profiles with T-slots which are modular and can provide good position adjustability for the seat, wheel and pedals. Only the frame itself can in many cases weigh more than 50-60 kg, and can occupy a floor area of 1.4 meter length by 66 cm wide. In
