Avionics - Display Management, Aural / Visual Indications, & Flight Instruments

Question 1

Which colors are on the EICAS and synoptic pages and what do they mean?

Answer 1

• Green: normal range
• Amber: caution range
• Red: limits exceeded
• Magenta: invalid data (unknown data)

Question 2

Which colors are used to depict the flow lines on the system synoptic pages?

Answer 2

• Black: no flow
• Amber: abnormal value
• Green: normal value
• Red: exceeding normal value
• Magenta: invalid (unknown data)

Question 3

What pilot actions are required after a DU failure?

Answer 3

• None inflight; all reversions are automatic
• If on the ground, the checklist will direct turning the DU to OFF and back ON to attempt a reset

Question 4

What is the result of pushing the EVENT pushbutton on the forward auxiliary panel on the center pedestal?

Answer 4

• Marks a moment in time in the data being recorded for future reference
• The data recorded will be higher resolution and contain more information than is normally recorded

Question 5

If current acceleration or deceleration is maintained, what does the airspeed trend vector represent?

Answer 5

The end of the trend vector line represents the projected speed in 10 seconds

Question 6

Based on current vertical rate, what does the altitude trend vector represent?

Answer 6

The end of the trend vector line represents what the altitude will be in 10 seconds

Question 7

How does the pilot change the selected altitude readout above the altitude tape from indicating feet to meters?

Answer 7

• Turn the large outer portion of the ALT knob on the FCP to “M”

Note: The tape doesn’t change to Meters. The metric value is added below the ASEL value in feet. The current metric altitude display appears below the value in feet.

Question 8

Will an air data source ADS failure on the ground automatically switch to an alternate air data source? (Rockwell Collins Avionics Operator’s Guide)

Answer 8

• No, the bad data will be removed, and red flags will be in their place

Note: Automatic reversion on ADS and IRS will not happen on the ground. Dispatch with avionics reversions are not permitted.

Question 9

What will happen to the system if an IRS failure occurs in flight?

Answer 9

• The side with the failure will automatically revert to IRS 3
• A cyan IRS 1 (2) FAIL CAS message illuminates
