STUDY GUIDE FLIGHT DECK/CREW AWARENESS Flashcards
Which displays can be reverted? Which can not?
- MFDs can revert 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 No auto reversion
- EICAS displays on the associated MFD
How many ADSs (Air Data Systems) are installed and how are they assigned?
5 ADS1 Captain ADS2 FO ADS3 Standby ADS4 IESS ADS5 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 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 it’s 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
