SCALE 3x

The first public demonstration of the 747 simulator was at a Linux trade show in February 2005. It was a great experience, the folks loved it, and there have been major improvements since that first model

747 Throttle Quadrant

More than just simple knock-offs, these provide interlocks to prevent reverse activation when throttles above idle or advancing throttles when reverse system is activated. There is also a reverse idle detent position to allow delay time for reverse system activation upon selection. Amount of reverse thrust may also be controlled by raising or lowering the reverse thrust levers.

MCDU Testing

The MCDU display and electronics connect to a standard 15-pin VGA connector. (No TV-out hack for this system) The keypad is encoded with a keyboard chip and decoded in software. A better solution is to use a custom Hagstrom encoder chip for detecting keypad entries.

AeroEnvironment Support

The basic set of boards provide 24 channels for rotary encoders, 8 A/D channels with 12-bit accuracy, and 128 positions for momentary, static, and rotary switches. Interface is provided via USB ports to a Linux based SBC. All boards contain logic and memory to retain data and event actions and set data ready flags for reading by applications programs via simple polling techniques. These boards can also be configured to operate with an interrupt-based protocol. Additional boards can be added in any combi nation as needed.

LFS software libraries and drivers provide plug and play support and clean and direct access to USB ports for reading data thereby facilitating development of application software. Low level output of raw binary data and switch action allows for a wide range of options for customization by the end users and flexibility in programming. In addition, the libraries and drivers can be modified by LFS to meet unique customer requirements.
