- Alert
- Memo
- Status
What are the three priority levels of alert messages?

- Caution
- Advisory
What is the highest priority alert message?
• Warning messages (red)
Can warning messages be canceled by pushing the CANC switch
• No
Can amber alert messages be canceled or recalled?
• Yes, by pushing the CANC switch or the RCL switch.
What is an advisory message?
- Lowest priority message (displayed in amber).
- Indented one space
- Can be canceled or recalled.
- Not tone or master caution light
Where is the most recent EICAS alert message displayed?
- At the top of its priority group.
* All messages move down one line.
Where is the most recent Memo message displayed?
• At the bottom of the memo messages
What is a memo message and where are they displayed?
- A reminder of selected state of controls or systems.
- Displayed in white
- Cannot be canceled
- Displayed at the bottom of the last page of EICAS alert messages.
Give examples of EICAS memo messages.
- APU RUNNING
- CON IGNITION ON
- SEATBELTS ON
- PACKS OFF
- AUTOBRAKES RTO
What does the STATUS Cue mean, and what color is the display?
- A new status message exists (Secondary EICAS)
* Cyan color
What is the function of the EIU selector in the AUTO position?
- Selects an operable EIU to provide data to EFIS and EICAS.
* Selects, left, then center, and then right.
If you had previously exceeded a parameter, such as an EGT limit for an engine, what would be displayed when pushing the RCL Switch?
• Redisplays a red box.
What alert displays are shown or displayed on the PFD?
- PULL UP (red)
* WINDSHEAR (red) (predictive windshear ahead or an immediate windshear is occurring.
When you receive a TCAS RA, where do you position the center of the airplane symbol on the PFD?
• Outside the red outlined RA pitch regions.
How many events can the EICAS Event Record Switch record?
• 5
Which type of EICAS message are listed in the DDG and provide a cross reference to the MEL for dispatch capability?
• EICAS Status Messages
Which engines, when advanced, will display the EICAS alert message CONFIG, if the airplane is not configured for takeoff?
• 2 or 3
What configuration conditions will cause the CONFIG message to display?
- Flaps not in a takeoff position
- Body gear not centered
- Parking brake set
- Speedbrake lever not in DN detent
- Stabilizer trim not in takeoff range
What conditions will cause the CONFIG GEAR EICAS warning message?
- The airplane is in flight, and
- Any landing gear not down and locked, and
- Any thrust lever is closed and the RA is less than 800 feet.
- Flaps in a landing position (25 or more)
When does the c-chord sound prior to reaching the selected altitude?
• 900 feet
How many feet off the selected altitude will cause the EICAS alert message ALTITUDE ALERT?
• 300 feet
Name some Ground Proximity Warning System features provided.
- Look-ahead terrain alerts
- Predictive windshear alerts
- Immediate windshear alerts
- Bank angle voice alerts
- Immediate alerts involving impact with obstacles and the ground.
- Altitude voice annunciations during approach
TERRAIN, TERRAIN, PULL UP voice annunciation sounds when how many seconds from projected impact with terrain? How about CAUTION, TERRAIN?
- 20 to 30 seconds – for TERRAIN, TERRAIN, PULLUP
* 40 to 60 seconds for CAUTION, TERRAIN
When are master CAUTION lights and Beeper inhibited during takeoff?
• 80 knots airspeed
New Predictive Windshear Warnings are inhibited at what airspeed during takeoff?
• 100 knots airspeed to 50 feet
When are Master WARNING lights and Bell for New EICAS warning messages FIRE inhibited during takeoff?
• At V1
What enables the takeoff CONFIG system?
- A/C on ground
- Fuel Control Switches in RUN
- ENG 2 or 3 thrust in takeoff range
- Airspeed less than V1
EGPWS features?
- Windshear
- Look ahead terrain
- Bank angle
- Immediate impact
- Altitude voice during APPS
How can amber EICAS be cancelled?
CANC Switch
* Recalled by RCL
When are takeoff CONFIG warning inhibited?
At V1
When is EICAS message PILOT RESPONSE displayed?
- Predefined time lapse after last switch action
- TOD passes with no recent switch action
When are MASTER CAUTION lights inhibited?
80 kts to 400’ RA or 20 seconds after Vr (whichever first)
FOR RTO initiated above 80 kts, inhibit continues until airspeed is less than 75 knots
When are MASTER WARNING lights inhibited?
V1 to 400’ RA or 25 seconds after V1 (whichever first)
If you have only one EICAS display on primary, how will you distinguished between Caution vs advisory
CAUTION will give you a master caution and a beep 4 tones
ADVISORY- only display the EICAS NOT master caution or tone
