Smaller Flight Data Recorders

Abstract

Data captured by flight data recorders are generally stored on the system's embedded hard disk. A common problem is the lack of storage space on the disk. This lack of space for data storage leads to either a constant effort to reduce the space used by data, or to increased costs due to acquisition of additional space, which is not always possible. File compression can solve the problem, but carries with it the potential drawback of the increased overhead required when writing the data to the disk, putting an excessive load on the system and degrading system performance. The author suggests the use of an efficient compressed file system that both compresses data in real time and ensures that there will be minimal impact on the performance of other tasks.

“…The actual altitude is commonly measured by an altimeter [15] and periodically recorded in the flight data recorder [16]; yet, the airplane altitude can be assessed using to this equation:…”

Efficient memory control for avionics and embedded systems

“…The memory of avionics system is typically small and there are many techniques how to make it smaller, e.g., Wiseman and Barkai (2013). An example of set of memory cards for avionics systems of Cypress Semiconductor Corp. can be seen in Figure 1.…”

Can Flight Data Recorder Memory Be Stored on the Cloud?

“…Up-to-date high density FLASH memory devices have facilitated the SSFDR (solid-state flight data recorder) to be manufactured with a substantially larger memory size. Many airplanes are now equipped with SSFDRs and no longer make use of disk drives (Wiseman & Barkai, 2013). Additionally, in the past twenty-five years, the density of memory chips has significantly multiplied, and the capability to record thousands of parameters for hundreds of flight hours in FDRs or quick assess recorders is now possible.…”
