CFDS747/777

CFDS Simulation Package for Boeing 747- 400 and 777

Application Scope

The CFDS747/777 is a dedicated application program to simulate the CFDS/OMS environment of both the Boeing 747-400 and 777, in a comprehensive and convenient way.

It operates in conjunction with the TechSAT ARINC 429 USB-device A429-USB (mobile) or PCI-card A429PCI-2G (stationary). A CFDS/OMS system package, consisting of an ARINC 429 device/card and the CFDS747/777 simulation software, forms a powerful and cost-effective tool to operate components with CFDS/OMS interface for development, diagnosis and repair purposes. The simulation can operate in two different, but very similar modes, covering all differences between the CFDS implementation in the two AC types.

The parameters of all cyclic CFDS/OMS labels can be manipulated. A dynamic function is available to generate time-dependent "Flight Phases" in order to perform entire flight-legs. A submenu allows interpreted monitoring of each FSW. Another submenu supports the complete "real-world" communication handshaking and data recording for non-interactive Initiated Tests.

All timing conditions and restrictions as defined in the appropriate Boeing specifications are fulfilled.

Received test results (FSWs) are recorded and displayed in FSW-interpretation. Shop data and configuration data access is realized in another submenu. MCDU data display and message dump is available. Equipment Identification information is displayed. Command Summary Word equipment identification can be configured.

All configurations can be saved to be active for future sessions.The entire ARINC 429 communication between an LRU and the CFDS simulation can be recorded.

An add-on tool (DataView) is provided that allows post-analysis of the communication for troubleshooting and documentation purposes.
