EDS

Question 1

Multi-function displays (MFD)

Fundamental operating principles?

Answer 1

• To enable the pilot to a have access to all these instruments in the one display
• Ease of view / reduce strain

Question 2

Electronic Flight Instruments Systems (EFIS)

Function?

Answer 2

• To put all the primary flight information into one display
• Increase the aircrew’s situational awareness by integrating all this information

Question 3

Electronic Flight Instruments Systems (EFIS)

Components?

Answer 3

• Display control panel
• Source control panel
• Symbol generator

Question 4

Electronic Flight Instruments Systems (EFIS)

What does the display control panel do?

Answer 4

• Control the format of the display on each of the electronic displays
• Where inputs by the pilot are used by other equipment, data buses broadcast the pilot’s selections so that the pilot only needs to enter the selection once.

Question 5

Electronic Flight Instruments Systems (EFIS)

What does the source control panel do?

Answer 5

• To select the type of information for display
• To select the source of information for display

Question 6

Electronic Flight Instruments Systems (EFIS)

What does the symbol generator do?

Answer 6

• Receives data inputs from the pilot (signals from various sensors and EFIS format selections)
• It has monitoring capabilities, a graphics generator and a display driver
• Checks for validity

Question 7

Engine Indicating and Crew Alerting System (EICAS)

Function?

Answer 7

• To monitor aircraft systems that were previously performed by a flight engineer
• Provide alerts to the aircrew if systems are operating out of acceptable parameters

Question 8

Engine Indicating and Crew Alerting System (EICAS)

Components?

Answer 8

• Primary display unit
• Auxiliary display unit
• Computers (left and right)
• Display select panel
• Maintenance control panel

Question 9

Engine Indicating and Crew Alerting System (EICAS)

What does the primary display unit do?

Answer 9

Displays the information that is critical to the pilot for the operation of the aircraft engines and for the displaying of aircraft faults.

Question 10

Engine Indicating and Crew Alerting System (EICAS)

What does the auxiliary display unit do?

Answer 10

• Allows the ICAS system to display other engine parameters not shown on the primary display
• Show aircraft systems in a schematic format to aid the aircrew in operating an aircraft system

Question 11

Engine Indicating and Crew Alerting System (EICAS)

What does the computers do?

Answer 11

• Two identical computers (left and right)
• Receive raw data from the aircraft systems and convert it into a useable format for display on the EICAS displays

Question 12

Engine Indicating and Crew Alerting System (EICAS)

What does the display panel do?

Answer 12

Select the desired data for display

Question 13

Engine Indicating and Crew Alerting System (EICAS)

What does the maintenance control panel do?

Answer 13

• Allows the selection of the system parameters for the overall system performance
• Clear faults
• Run tests
• View different pages

Question 14

Electronic Centralised Aircraft Monitor (ECAM)

Function?

Answer 14

• Same job as engine Indication and Crew Alerting
• Monitor and display the condition of the major mechanical, electrical and environmental aircraft systems

Question 15

Electronic Centralised Aircraft Monitor (ECAM)

Components?

Answer 15

• Display units
• Flight warning computer (FWC)
• System data acquistion concentrator (SDAC)
• Display management computer (DMC)
• ECAM control panel
• Master warning and master caution lights
• Audio speaker

Question 16

Electronic Centralised Aircraft Monitor (ECAM)

What do the display units do?

Answer 16

• Cathode ray tube or liquid crystal display types and interchangeable with EFID DUs
• Mounted vertically
• Upper DU provides engine / warning information
• Lower DU provides system / status information in graphical or synoptic format

Question 17

Electronic Centralised Aircraft Monitor (ECAM)

What does the flight warning computer do?

Answer 17

• Acquire the data needed to generate warning and caution messages associated with system fails

Warnings: The data is acquired directly from sensors and systems

Cautions: The data is acquired from SDACs

Question 18

Electronic Centralised Aircraft Monitor (ECAM)

What does the system data acquisition concentrator do?

Answer 18

• Connected to aircraft system sensors
• Acquire data corresponding to caution situations
• Send to the 3 DMCs
