  • Real-time data recording and retrieval
  • Redundant power supply for continuous operation
  • Compliance with international aviation standards

2.3 System Architecture

The FDRS consists of the following main components:

  • Flight Data Recorder (FDR)
  • Data Acquisition Unit (DAU)
  • Cockpit Voice Recorder (CVR)
  • Data Interface Module (DIM)
  • Power Supply Unit (PSU)

3. Components

3.1 Flight Data Recorder (FDR)

  • Description: The FDR is the primary component responsible for recording flight data parameters.
  • Specifications: High-capacity solid-state memory, ruggedized for crash survivability, real-time data recording.
  • Location: Installed in the aircraft's avionics bay.

3.2 Data Acquisition Unit (DAU)

  • Description: The DAU collects and processes data from various aircraft sensors and systems.
  • Specifications: High-speed data processing, multiple input channels, real-time data transmission.
  • Location: Installed in the aircraft's avionics bay.

3.3 Cockpit Voice Recorder (CVR)

  • Description: The CVR records audio from the cockpit, including pilot communications and ambient sounds.
  • Specifications: High-fidelity audio recording, crash survivable memory unit.
  • Location: Installed in the aircraft's avionics bay.

3.4 Data Interface Module (DIM)

  • Description: The DIM interfaces with the aircraft's data bus and transmits data to the FDR and CVR.
  • Specifications: High-speed data interface, multiple communication protocols.
  • Location: Installed in the aircraft's avionics bay.

3.5 Power Supply Unit (PSU)
