Optimizing Flight Data Recorder Modification Requirements
Cockpit Voice and Flight Data Recorders (CVFDR’s) are necessary for many aircraft to provide valuable information to accident investigators following an incident and most aircraft need CVFDRs to meet regulatory requirements. Typically, modifications are required to meet an aircraft’s interface requirements, current regulations or to accommodate additional data for other applications. Such modifications may be costly or can require additional LRUs to fulfill requirements due to the high cost of modifying safety-critical equipment.
Changes in regulations and the desire to gather more data can result in managing different CVFDRs across fleets and in multi-box solutions. One solution is to design CVFDRs with the ability to house data acquisition and processing modules and to accommodate anticipated future regulation changes.
This white paper discusses how, using modular design methods, modifications can be simple and how the resulting inbuilt functionally can help reduce costs and lower overall weight and space requirements.
