Which displays can be reverted? Which displays cannot be reverted?
• MFDs can be reverted to either EICAS or PFD
• PFDs and EICAS cannot be reverted
-
Explain the ‘AUTO’ functions of the EDS REVERSIONARY panels
• EICAS failure: Each MFD displays EICAS
• PFD failure: Respective MFD displays associated side PFD
• MFD failure: No auto reversion
-
Explain the ‘PFD’, ‘MFD’, and ‘EICAS’ selections on the EDS REVERSIONARY panel
- • PFD: Respective PFD will display on associated MFD
- • MFD: MFD cannot be reverted
- • EICAS: EICAS displays on the associated MFD
-
How many ADSs (Air Data Systems) are installed and how are they assigned?
5 installed
- ADS 1 Captain
- ADS 2 First Officer
- ADS 3 Standby
- ADS 4 IESS
- ADS 5 Flight Controls
-
What happens if ADS 1 or 2 fails?
• ADS 3 automatically becomes the source
• If ADS 3 fails, then the respective x-side ADS is used (i.e. ADS 1 reverts to ADS
-
What happens if the ADS button is pushed?
• The respective onside ADS reverts to ADS 3
• The respective onside ADS reverts to the x-side ADS if the button is pushed a second time
• The respective onside ADS returns if the button is pushed a third time unless the respective side is already failed
-
Is there an automatic reversion for an IRS failure?
No, it must be manually reverted
-
What happens if the IRS button is pushed?
The respective IRS to the x-side IRS source
-
How would the pilot know if the ADS or IRS reversion button has been pushed?
An ADS or IRS flag would be displayed on the associated PFD
-
What is the primary flight instrument if both IRS’s fail?
IESS
-
What type of approach is prohibited using the IESS?
LOC BC
-
When will the EICAS de-clutter?
30 seconds after gear and flaps are up and all system parameters are normal
-
What is the function of the EICAS FULL button?
Inhibits the automatic de-clutter of the EICAS
-
When will the EICAS display all of its information?
• When the gear is down, flaps are extended, or spoilers are deployed under normal conditions
• APU running
-
What color is the course needle (CDI) when using the FMS, VOR/LOC, and x-side data?
• FMS Magenta
• VOR/LOC Green
• X-side info Yellow
-
What runways are included in the database of the EGPWS?
Runways > 3500’ with a published approach
-
How long until impact with a terrain alert on EGPWS?
• RED 30 sec
• AMBER 60 sec
-
When should the ‘GND PROX TERR INHIB’ button be pushed?
To cancel unwanted terrain alerts when operating at airports not in the EGPWS database
-
What will generate a windshear caution? Warning?
• Caution: Increasing headwind and/or updrafts
• Warning: Decreasing headwind, increasing tailwind, and/or downdrafts
-
What our policy for windshear encounters?
• Caution: Captain/crew discretion
• Warning: Firewall thrust and climb in current configuration until warning ceases
-
How is the pilot alerted during a windshear?
• Caution: Amber windshear flag on PFD / aural “CAUTION, WINDSHEAR”
• Warning: Red windshear flag on PFD / aural “WINDHEAR, WINDSHEAR, WINDSHEAR
-
Will the autopilot deactivate during windshear guidance?
yes
-
How long will the windshear alerting last?
Until 1500’ RA
-
Will the windshear alerting system function if both radar altimeters and/or EGPWS are inop?
no
-
What is checked when the ‘T/O CONFIG’ button is pushed?
- • Parking brake Off
- • Spoilers Stowed (not deployed)
- • Flaps Set for takeoff
- • Pitch trim Set for takeoff
-
What does a red ATT or HDG flag on a PFD indicate?
Attitude or Heading reference cannot be determined by the associated IRS
-
What does a red ‘X’ on the ASI, altimeter, or VSI indicate?
Airspeed, altitude, or vertical speed cannot be determined by the ADS
-
What is the function of the ‘GND PROX GS INHIB’ button?
To cancel unwanted glideslope alerts below 2000 ft
