Electronic Display

Question 1

When do the red chevrons appear on PFD?

Answer 1

The red chevrons will display starting on the
30 degree line when the pitch angle exceeds 25 degrees nose up.
They will disappear when the pitch angle returns to less than
20 degree nose up.

The pitch chevrons are displayed, starting on the 20-degree line,
when the pitch angle exceeds 25 degrees nose down. They will
disappear when the pitch angle returns to less than 10 degrees
nose down.

Question 2

When does BETA index appear, when is it filled, when is it empty?

Answer 2

Falp/Slat out = Filled
Flap/Slat retracted = Empty

Question 3

Question 4

After how many degrees differecnce in ROLL, the EFIS MISCOMPARE show up?

Answer 4

4 deg bank angle difference between the PFDs

Question 5

After how many degrees differecnce in PIT, the EFIS MISCOMPARE show up?

Answer 5

4 degrees normal, 3 degrees on Glideslope difference between the PFDs

Question 6

4After how many degrees differecnce in ATT, the EFIS MISCOMPARE show up?

Answer 6

4m deg difference in Pitch and Attitude between the PFDs

Question 7

What happens if invalid pitch and roll angles are detected?

Answer 7

All indications are removed from ADI

Question 8

When does a ghost FPV appears?

Answer 8

When in large crosswind conditions, the flightpath trajectory is putside the attitude display.

Question 9

What are these called and waht they represent?

Answer 9

Acceleration cue and speed error tape. Each green horizontal line represents 5kt

Question 10

What does the end of the green airspeed vector represent?

Answer 10

The speed the AC will achieve in 10 seconds

Question 11

How is minimums speed at the sidestick aft stop represented?

Answer 11

Question 12

How is stall marker displayed on the speed tape?

Answer 12

The solid red line. It’s the minimum speed FBW allows when the sidestick is moved to the Hard stop.

Question 13

What markers are removed from the lower speed tape in Dorect mode?

Answer 13

Low speed marker, so from minimum trim goes direct into stall with aural warning.

50-foot increments between 1500 and
2500 feet,
10-foot increments between 200 and 1500 feet
5-foot increments between −20 and 200 feet
