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 2) |
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 faile |
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 |
