Diminishing Flight Data Recorder Size
نویسنده
چکیده
Flight Data Recorders produce data that is stored on an embedded memory device. A widespread problem with these devices is that the embedded memory device runs out of space. The concern of getting to this problematic situation causes the software of the flight data recorder to work in a careful manner it constantly makes efforts to minimize the used memory space; otherwise a larger flight data recorder will be required that will also cost more money. In this paper we propose using a compressed file system with the aim of having a better cost-effective memory usage. The main significant disadvantage that sometimes prevents flight data recorders from using compressed file systems is the intense overload of data compression when writing the data to the memory device, which puts an intolerable overburden on the processor and as a result it harms the system performance. This paper proposes a file system that instantaneously compresses the data of the flight data recorder while taking care that the other tasks' response time will not be harmed.

A review on Ejectable Versus Non-Ejectable Flight Data Recorder
Flight recorders, often called “black box” are two devices designed to record data about flights. Flight Data Recorders (FDR) record various flight parameters. All aircraft’s are required to have Flight Data Recorder (Black) systems installed in it. Depending on aircraft, manufacturer can either use Non-Ejectable Flight Data Recorder or Ejectable Flight Data Recorder. This requirement is implem...
