Aircraft Systems Quiz

The ability to change between different modes of operation using the Elapsed Time (ET) button. The Chronometer function switch (CHR) is set to the SET position.

Displays the current minute in Greenwich Mean Time (GMT).

Displays the current hour in Greenwich Mean Time (GMT).

Displays the current minute in the aircraft's local time zone.

A switch that controls the different functions of the chronometer, such as the time displays.

The time elapsed since the start of a flight, measured in hours and minutes.

The digital display area on the chronometer that shows the elapsed time in hours and minutes.

The time elapsed since the start of a flight, measured in hours and minutes. It is displayed in the lower digital display area of the chronometer.

The SSFDR is painted bright orange and marked with "FLIGHT RECORDER DO NOT OPEN" in English and French. It also has reflective tape for easier recovery.

The SSFDR is designed to withstand extreme weather conditions without needing forced air cooling.

The SSFDR is located in the rear fuselage of the aircraft between specific station points.

The SSFDR is mounted in a ½ ATR short mounting tray, which is electrically bonded to the aircraft by a strap.

On aircraft with specific modifications, the SSFDR tray is directly mounted to the aircraft structure using bolts, which provides bonding to the chassis ground.

The SSFDR is specifically designed to operate in extreme environmental conditions.

The maximum DC current of the SSFDR is less than 500 mA, with a switch current rating of 5 A at 28 VDC.

The inertia switch connector is installed on the side panel of the SSFDR.

The ability to select chronometer functions by pressing the CHR button. Each press cycles through start, stop, and reset.

The two buttons used to increase or decrease the value of the elapsed time (ET) display.

The chronometer function can toggle between ET (elapsed time) and CHR (chronometer) using the ET SEL or CHR buttons.

The chronometer receives power from both the left essential and right main busses, with backup from the battery bus. This ensures constant power for accurate time keeping.

The chronometer provides data to various systems, including the flight data recorder (FDR) and cockpit voice recorder (CVR), for flight data recording.

The chronometer displays the time in Greenwich Mean Time (GMT). This is the standard time used for aviation globally.

The chronometer provides the date information to the Flight Data Processing System (FDPS) located in the Integrated Flight Cabinet (IFC1)*. It helps record when system malfunctions occurred.

The Flight Data Recorder Test switch is located on the overhead Flight Data Recorder panel in the cockpit, and it allows power to the SSFDR when set to GND TEST position.

If the SSFDR BITE indicates successful operation, the FLT DATA RECORDER light on the caution panel will turn off. This switch allows the SSFDR to be tested on the ground without needing to turn on the aircraft's main power.

The anti-collision lights switch, located on the overhead EXTERIOR LIGHTS panel, allows for the activation of the anti-collision lights in either red or white mode, bypassing normal power removal circuits. The switch bypasses 'on ground' power removal circuits, making the lights functional on the ground.

The anti-collision lights switch has three positions: RED, OFF, and WHITE. This switch, located on the overhead EXTERIOR LIGHTS panel, operates the anti-collision lights, which are safety lights designed to make an aircraft easily visible on the ground.

The SSFDR, or Solid State Flight Data Recorder, is the recorder device that stores flight data. This device is activated by the Flight Data Recorder Test switch, which provides power to the SSFDR in GND TEST mode.

Processes data from various aircraft and avionics sources to create records for the Flight Data Recorder (FDR).

The initial stage of FDPS operation, where it performs self-checks and configuration setup.

A comprehensive test run by the FDPS upon power-up to verify its functionality.

The primary operational state of the FDPS when it's processing data and performing its functions.

A dedicated mode where technicians can access the FDPS for maintenance, diagnostics, and software updates.

The process of sending new software instructions to the FDPS, allowing for upgrades and fixes.

A function of the FDPS that ensures the correct operation of the aircraft's configuration settings.

The FDPS converts data from various sources into a standardized language used in the aviation industry.

The FDPS monitors crucial parameters like aircraft systems, ensuring they operate within safe limits.

The FDPS analyzes the memory where data is stored, ensuring its proper functioning.

The IOP FAIL messages appear on the Electronic Display (ED) when the IOP1 or IOP2 (Input/Output Processors) or the interface between them and the ED malfunctions.

The IOP BAD CONF message indicates that an IOP has detected an incorrect aircraft configuration. This message is shown when the aircraft is on the ground.

The BALANCE message is displayed when the left or right fuel gauging computers detect an imbalance in fuel distribution. It flashes for five seconds and then remains steady.

The INCR REF SPEEDS message is shown when the Stall Protection System (SPS) changes its stall sensing for icing conditions. This occurs when the aircraft is on the ground and the engines are not running.

The IOM FAIL messages indicate a malfunction in the Input/Output Modules (IOMs). These messages are displayed when IOM failures are detected.

The WTG FAIL messages show when the Wind Tunnel Generators (WTG) malfunction. These messages are displayed when the aircraft is on the ground and the engines are not running.

Advisory messages are displayed on the Electronic Display (ED) to inform the pilot about various system conditions. The messages are displayed in order of decreasing importance, with the most important message appearing at the bottom of the ED.

The FDPS (Flight Data Processing System) is responsible for sending advisory messages to the Electronic Display (ED).
