Indicating & Recording

Question 1

What does the EICAS provide

Answer 1

Automatic system monitoring
Aural alerts
Color logic for presentation of minimum/maximum limits
Integration of system information

Question 2

How many EICAS displays are there

Answer 2

There are two different displays. ED1 (on the left side, usually on the primary page) and ED2 (typically on the status page but is the screen where we usually go through the different pages)

Question 3

What’s a data concentrator unit (DCU)

Answer 3

Heart and brains of the EICAS system. Determines what color to make something and what to display on the EICAS screens. Receive information from thousands of different aircraft sensors.

Question 4

What is a white colored EICAS message mean

Answer 4

Status message

Question 5

What kind of displays are the

Answer 5

Cathode Ray tube displays. They get very hot.

Question 6

Do the EICAS screens come on with the battery master

Answer 6

Yes. But until the APU gets powered up there’s no AC power in the aircraft which means the cooling fans aren’t available. THE EICAS displays will overheat so there’s a 5 minute limitation with just the battery.

Question 7

Can the audio warnings be turned off

Answer 7

Yes they can, by pressing the guarded audio switches on the FO’s right leg. Need to coordinate with the other pilot before pressing. Should almost never be disabled.

Question 8

Lamp driver unit

Answer 8

Connected to the DCU and determines which lights illuminate.

Question 9

Master caution light

Answer 9

• Single chime
• Won’t stop flashing until you press it
• always, “cancel, identify” then the pilot flying will say, “I have the radios and controls. Get the QRH”read the the EICAS to identify and then go the QRH.

Question 10

Master warning light

Answer 10

• Triple chime
• These are more urgent
• “cancel, identify” “I have the radios and controls”

Question 11

Warning

Answer 11

Indicates a condition that requires immediate actions. Cannot be boxed.

Question 12

Caution

Answer 12

Indicates a situation that requires prompt action. Can be “boxed” which means it can be sent to a folder to declutter the EICAS. To box the caution messages you hit the CAS button on the EICAS page panel.

Question 13

Advisory message

Answer 13

Indicates that a safe configuration exists. Green in color. Cannot be boxed.

Question 14

Status message

Answer 14

Indicates that a particular aircraft state exists. Not necessarily good or bad. Can be boxed by pushing the STAT button.

Question 15

How are messages grouped.

Answer 15

Within each type of message they are displayed chronologically. Each different type group is displayed according to severity, warning, caution, advisory, status.

Question 16

Stall advisories

Answer 16

Shaker, then pusher, then warbler aural sound.

Question 17

How many aural warning types are there?

Answer 17

10. Should try to be aware of them all.

Question 18

Can the aircraft give you more than one aural warning at a time?

Answer 18

No. If multiple sounds are required it will play them in order of priority.

Question 19

EICAS control panel

Answer 19

Located on the center pedestal between the pilots. Has buttons with the different pages that can be displayed. Step button goes through each page in order on ED2, which is useful if one of the page buttons is inop.

Question 20

Flow line color

Answer 20

Green is normal flow
Amber is low flow
Black is no flow
Red is too high flow

Question 21

MFD reversionary mode

Answer 21

Can be in normal, EICAS and PFD mode. So the MFD can display whatever you want t depending on how its selected.

Question 22

Source selection panel

Answer 22

Normal, ED1 and ED2 selection. Normal leaves the EICAS in ED1 being primary and ED2 displaying other pages.

Question 23

EICAS message inhibit logic

Answer 23

The DCU’s will process inhibit logic to minimize spurious or distracting warning and/or caution messages during the takeoff and landing phases.

Question 24

Inhibit 1

Answer 24

Failures won’t be shown on takeoff until 400’AGL

Question 25

Inhibit condition 2

Answer 25

Above 100 knots

Question 26

Inhibit condition 3

Answer 26

Won’t come on during landing (below 400’ AGL) under 30s after weight on wheels.

Question 27

Takeoff config advisory message

Answer 27

To get the message you need to have 7 things 
-3 trims in green
-parking break off
-flaps 8º or 20º
-
-

Question 28

Takeoff config warning

Answer 28

Armed when on the ground and both engines above N1>70%

Question 29

PASSFAR

Answer 29

Parking break - off
Autopilot - off
Spoilers - retracted
Stab trim - green
Flaps - 8º or 20º
Aileron trim - green
Rudder trim - green

Question 30

Maintenance diagnostic computer (MDC)

Answer 30

Used to record aircraft mechanical avionics system data. Need to flip the red switch on circuit breaker panel one (behind the captains seat) in order…

Question 31

Flight data recorder

Answer 31

• Records the last 25hrs of flight data
• Sends information via “flight operations quality assurance (FOQA)” to your company. Can’t be used for disciplinary action but the information is sent to flight safety. That data can be used to determine if you need retraining or other actions required by flight safety.
• Starts when either the beacon or strobe lights are turned on. If you forget it will also go on with weight off the wheels.

Question 32

Cockpit voice recorder

Answer 32

Records last 2 hours on a loop. Starts with battery master on.
