4 Air Data Smart Probes (ADSP)
2 Total Air Temperature Probes (TAT)
3 Air Data Applications (ADA)
What are the yellow boxes around the ADSPs?
RVSM Critical area
What is green dot?
Drift down speed. Provides a margin of 1.3g over stick shaker speed
Which displays can be reverted?
MFDs (DU 2 and DU 4)
Which displays cannot be reverted?
DU 1 and DU 5 (PFDs) and DU 3 (EICAS)
How are Air Data Systems assigned?
ADS 1- Captain ADS2 - First Officer ADS 3 -Standby for captain or first officer ADS 4 - IESS ADS FCS - Flight Controls System
What do the takeoff guidance crossbars give you?
Maintains extended runway centerline and pitch attitude based on flap selection, airplane weight, and V2 speed.
What are the AUTO functions of the REVERSIONARY Panel MFD DISPLAYS MODE Selector knobs in the PFD, MFD, and EICAS positions?
a. Automatically reverts the MFD in case of display failure
b. EICAS failure- each MFD displays EICAS
c. PFD failure- respective MFD displays associated side PFD
d. MFD failure- no auto reversion
What displays when the REVERSIONARY panel MFD DISPLAYS MODE selector knob is in the PFD, MFD, and EICAS positions?
a. PFD- Displays PFD information in the associated MFD
b. MFD- Displays MFD information in the associated MFD
c. Displays EICAS information in the associated MFD
What happens if the associated ADS button is pushed in?
a. Reverts the ADS source:
- Respective onside ADS reverts to ADS 3
- Respective onside ADS reverts to the cross side ADS if the button is pushed a second time
- Respective onside ADS returns if the button is pushed a third time unless the respective side is already failed
What indication displays when the ADS or IRS pushbutton is pushed in?
a. A white stripe bar illuminates on the button
b. Associated ADS or IRS source flag is displayed on the PFD
What happens if ADS 1 or 2 fails?
ADS 3 automatically becomes the source. If ADS 3 fails, then the respective cross side is ADS is used.
How long does the IESS take to align?
90 seconds
What is important about the IESS time to align?
Do not move the aircraft during this time. If so, it could cause inflight attitude indication errors that may not be noticeable on the ground
