Cockpit Voice and Flight Data recorders (CVR/FDR) recorders are designed to protect data in extreme environmental conditions to ensure reliable access to cockpit voice and flight data following an incident. They are mandated for many aircraft, and desirable for many others, but not all aircraft have a suitable data stream available to output the required information. There is also a trend towards using the flight recorder system as an active component in aircraft maintenance, expanding its role to include applications such as Flight Operations Quality Assurance (FOQA) and Condition Based Maintenance (CBM).
Curtiss-Wright provides a solution for these needs with a fully qualified CVR/FDR and an easily customizable Flight Data Acquisition Unit(FDAU). This allows for a highly customized system to be delivered without the high costs associated with bespoke designs and easily accommodates small production quantities.
The Multi-Purpose Flight Recorder (MPFR) is a compact, low-weight combined CVR/FDR that is fully approved for current requirements. It features a 90 day Ultrasonic Locator Beacon (ULB) option, attaches directly to airframe and has fast Ethernet and wireless data recovery options.
The FDAU is a rugged, compact unit with a configurable modular design that has out of the box connectivity to the MPFR product line. Chassis are available in a number of sizes and can be hard-mounted in any orientation on an airframe. Along with a wide range of analog, digital, bus, audio and video modules, Built-In Test (BIT), GPS and onboard processing modules are also available.
Thus, this crash recorder system is ideal for applications where a CVR/FDR is required and a large digital/analog parameter set must be captured. In this situation, a commercial off-the-shelf configurable FDAU can acquire/process the mandatory parameters and send the appropriate ARINC data stream to the MPFR.
The system can also be used to support an aircraft maintenance system. Additional modules can be used to acquire data from sources such as strain gauges and accelerometers and the FDAU can send the required parameters to a separate quick access recorder (QAR).
