What main information is displayed on the PFD?
Airspeed, Altitude, ADI, HSI, Vertical Speed Indicator, Flight director, Radio altitude data, Radio Aids, Autopilot
AMS 2-17
If information is mismatched between 2 PFDs what happens?
No information at all will be presented
ASM 2-17
Which display has the menu softkeys?
MFD
ASM 2-20
The MFD presents what 2 navigation formats?
Map and Plan
What is the third primary function of the MFD?
Displays various systems synoptic formats
What does EICAS stand for?
Engine Indication and Crew Alerting System
ASM 2-22
In addition to crew alerting, what else does the EICAS display?
Engine and various system parameters such as flaps, gear, spoilers, trim, fuel, APU, and environmental
ASM 2-22
Which displays can be reverted? Which displays cannot be reverted?
- MFDs (DU 2 & 4) can be reverted to either EICAS or PFD
- PFDs (DU 1 & 5) and EICAS (DU 3) cannot be reverted
ASM 2-17
What is the reversionary priority (highest to lowest)?
- PFD, 2. EICAS, 3. MFD
ASM 2-17
How many reversionary panel controls are in the airplane?
2, one for each pilot
ASM 2-31
What does DU3 always display?
EICAS
Which display units will always operate as primary flight displays?
DU1 and DU5
What happens with the DISPLAYS selector in AUTO?
- EICAS failure EICAS is displayed on associated MFD
- PFD failure Respective PFD displays associated side MFD
- MFD failure No auto reversion
Explain the ‘PFD’, ‘MFD’, and ‘EICAS’ selections on the REVERSIONARY panel
- PFD Respective PFD will display on associated MFD
- MFD MFD cannot be reverted
- EICAS EICAS displays on the associated MFD
- Automatically reverts the MFD in case of display failure
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
How would you display the Captain’s PFD on DU 2?
On the Captain’s reversionary panel move the selector to PFD
What happens if ADS 1 or 2 fails?
ADS 3 automatically becomes the source, If ADS 3 fails, then the respective cross-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 xXside 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
What indication would you get when you push the ADS or IRS pushbutton?
A white striped bar illuminates on the button
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
Is there an associated ADS or IRS source flag displayed anywhere?
Yes, on the PFD
Briefly describe what a Modular Avionics Unit (MAU) is?
It’s a cabinet that houses modules assigned to different functions in an integrated architecture and also avionics and non avionics functions
Where are MAUs 1 and 2 located? MAU 3?
1 & 2 are in FWD Electronics bay. 3 is in Central Electronics Bay
