How many EIUs are installed?
3
What are the three priority levels of EICAS Alert messages?
Warning, Caution, Advisory
The cyan STATUS cue on the primary EICAS display is inhibited when?
Engine start to 30 minutes after liftoff or if Secondary Engine Exceedance cue is displayed
With the transponder mode selector in TA/RA and the TCAS traffic display selected ON with the EFIS TFC switch, what is the cyan TCAS mode annunciation on the ND prior to takeoff?
TFC with TA ONLY below
Prior to takeoff CPT has TERR selected on ND while FO has WXR selected for his ND. During takeoff roll at 80 kts a PWS warning is detected ahead of the the aircraft. What is displayed on the CPT ND?
Only the red warning annunciation WINDSHEAR is displayed on the ND
TCAS information is not available in which ND mode?
PLAN
During takeoff, when are Caution Alerts inhibited?
80 kts
During takeoff, when are PWS warnings inhibited?
100 kts
What are the three types of EICAS messages on the -400?
Alert, memo, status
During takeoff, when are Warning Alerts inhibited?
V1
How long will the Alert message CONFIG message remain displayed?
The CONFIG message remains displayed until the airplane is configured for a normal takeoff or until engine 2 and 3 thrust is decreased below takeoff range and airspeed is less than V1.
Proximate traffic is another aircraft that is neither a RA nor a TA but is within ___ NM and ___ feet vertically.
6, 1200’
All EICAS status messages are listed in the dispatch deviation guide and provide a cross reference to what document for dispatch capability?
MEL
Which ND modes will not display TCAS messages and TCAS traffic symbols?
VOR centered, approach centered, or plan
During the takeoff roll but prior to 80 kts, how can an advisory alert message be distinguished from a caution alert message?
No aural associated with advisory message

250, 2000
On takeoff the immediate windshear warning WINDSHEAR WINDSHEAR WINDSHEAR is active when?
Rotation until 1500’ RA
Immediately after takeoff and above 400’ RA the WX radar indicates a PWS symbol 2 NM directly in front of the aircraft. What owuld the PWS alert voice annunciate?
MONITOR RADAR DISPLAY
During descent and approach, PWS alerts are enabled at what altitude?
1200’ RA
The EICAS caution message ENG FAIL is inhibited when?
On the ground until liftoff
Which improper configurations would trigger a takeoff configuration warning?
Stab trim not in the takeoff range, flaps not in takeoff position, body gear not centered, parking brake set, or speedbrake lever not in DN detent
What conditions will generate an Immediate Windshear Warning?
Excessive downdraft or excessive tailwind is occurring
