A330 ATA 31 RECORDING

What is the primary function of the Digital Flight Data Recording System (DFDRS)?. To monitor real-time flight parameters for pilot reference. To fulfill the mandatory requirements of crash recording. To transmit data to air traffic control for monitoring purposes. To provide entertainment options for passengers during flight.

What components are included in the DFDRS architecture?. Flight Data Interface Unit (FDIU), Linear Accelerometer (LA), Event P/B, Recorder Ground Control P/BSW, Quick Access Recorder (QAR). Flight Data Recorder (DFDR), Cockpit Voice Recorder (CVR), Flight Data Interface Management Unit (FDIMU), Linear Accelerometer (LA). Flight Data Interface Unit (FDIU), Quick Access Recorder (QAR), Recorder Ground Control P/BSW, Event P/B, DFDR. Flight Data Recorder (DFDR), Linear Accelerometer (LA), Aircraft Tail Number, Fleet Identification.

What is the function of the Flight Data Interface Unit (FDIU)?. To collect various basic aircraft system parameters and convert them for recording. To control the aircraft's flight path and altitude. To collect various aircraft system parameters and recording. To communicate with air traffic control towers.

Where is the FDIU typically located?. In the cockpit center pedestal. In the aircraft center of gravity. In the avionics bay. In the passenger cabin.

What information does the DFDRS Coding Panel provide to the FDIU?. Aircraft tail number, airline identification, fleet identification. Pilot's name, flight route, departure time. Engine temperature, fuel level, cabin pressure. Air traffic control frequency, weather updates, navigation waypoints.

What is the purpose of the Linear Accelerometer (LA) in the DFDRS?. To measure the aircraft's speed. To provide data on three axes of acceleration to the FDIU. To monitor engine performance. To control cabin temperature.

Where is the Linear Accelerometer (LA) installed in the aircraft?. In the avionics bay. In the cockpit center pedestal. In the aircraft center of gravity. In the passenger cabin.

How does the FDIU receive information from the Linear Accelerometer (LA)?. Via the System Data Acquisition Concentrators (SDACs). Via direct cable connection to the DFDR. Through wireless transmission. By manual input from the pilot.

What is the function of the EVENT P/B in the cockpit?. To initiate emergency procedures. To record an event mark in the DFDR memory. To activate the autopilot system. To control cabin lighting.

How many hours of data can the DFDR store?. 10 hours. 25 hours. 48 hours. 100 hours.

How does the EVENT P/B assist technicians in identifying specific events?. By marking events with a timestamp. By highlighting events on the cockpit display. By generating a notification to maintenance personnel. By triggering an alarm in the cockpit.

Where is the Quick Access Recorder (QAR) typically installed?. In the cockpit center pedestal. In the passenger cabin. In the avionics compartment. In the aircraft center of gravity.

How is the power supply to the DFDR and QAR controlled?. It is controlled manually by the flight crew. It is controlled automatically based on engine activity. It is controlled by a separate power management system. It is controlled by the cockpit voice recorder.

When does the DFDR power up automatically?. When the aircraft is taxiing. When one engine is started. When the aircraft is in cruise mode. When the aircraft is descending.

How long does the DFDR remain powered after the last engine shutdown?. It remains powered until manually switched off by the flight crew. It remains powered indefinitely. It remains powered for five minutes after the last engine shutdown. It remains powered for ten minutes after the last engine shutdown.
