Capt has an additional 71° with tiller for a total of 76°

Question 7

What considerations should be taken when operating the pilot seats on the ground?

Answer 7

Do not operate the electrical positioning adjustments on batteries only (you only have 14-15 mins of batt on the ground after you power up).

Question 8

How should you respond to a TCAS RA

Answer 8

1/4 to 1/2 G maneuvers (Gentle) in accordance with the RA advisory (get the VSI needle in the Green).

What are DAUs

Answer 11

Data aquisition units - send data to the IC600s

What is DAU 1, what is it dedicated to and what happens if it fails

Answer 12

It is the primary channel, dedicated to FWD systems & Eng 1. If fails you will get an EICAS message and amber dashes.

Question 13

What is DAU 2, what is it dedicated to and what does it do if DAU 1 goes off line.

Answer 13

It is the backup channel, dedicated to the rear systems and Eng 2. It will be in use if the primary goes offline but does not give everything from primary.

Answer 14

IC600#1: PFD1, MFD1 & EICAS

IC600#2: MFD2, PFD2

Question 15

What happens to the displays if either IC-600 fails. How do you get cross side data

Answer 15

• If either IC600 fails, push reversionary panel button to get cross side data.

Question 16

What problems may exist if a display screen goes dark?

Answer 16

• Dimmer Switch may be on
• Failed Tube
• Electrical Failure/ Loss of power to tube.

Question 17

What are the power sources for various screens?

Answer 17

• DC1 powers: PFD1, MFD2
• DC2 powers: MFD1, PFD2, TBCH
• Essential 1 powers: RMU1, EICAS
• Essential 2 powers: RMU2

Question 18

During an IC600 level 1 test, what should you see?

Answer 18

• Big Blue Ball on attitude indicator
• Red Xs on Airspeed and Altimeter
• Amber Dashes on numerical values.

Question 19

What consideration should you consider when conducting the IC600 level 2 test

Answer 19

All items will pass reletivly quickly and in sequence, but Radio Altimeter takes a longer time to pass (keep pushing button until each passes).

Question 20

How long does it take for Blue ICAS messages to stop flashing after being displayed

Answer 20

After 5 seconds.

Question 21

How will EICAS messages in excess of 15 be displayed, and how do you access them?

Answer 21

MESSAGES with a down arrow is diplayed in yellow, you can view them by rotating the control knob at the bottom of the EICAS panel.

Question 22

What is the purpose of takeoff and landing inhibition logic?

Answer 22

to eliminate neusance messages that might cause a distraction to pilots when close to the ground (pretty much all messages are considered neusance).

Question 23

When is takeoff inhibition logic valid from and to?

Answer 23

Valid from V1 - 15kts to:

1) Radar Alt of 400ft agl
2) 1 min if RA failure
3) CAS < 60kts if a T/O abort.

Question 24

When is landing Inhibition Logic Valid From and To

Answer 24

Valid from RA of 200ft agl to:

1) Weight on Wheels + 3 secs
2) After 1 min if you go around.

Question 25

How do you deal with CAS messages (non EICAS)?

Answer 25

Go to Message Miscomparison checklist in the QRH and follow the associated checklist.

Question 26

What Aural warnings will be sounded if the Aircraft is not properly configured for T/O

Answer 26

Flaps

Trim

Brakes

Spoilers

Question 27

What are the elements of the stall system

Answer 27

1 stall computer with 2 channels

2 stick shakers

1 stick pusher

Question 28

Which side (Captain or FO) is the stick pusher control attached

Answer 28

Captains side cable run

Question 29

When will the stick pusher not push

Answer 29

5) If only on one computer channel (other is inop or de-selected).
6) On the ground except in TEST.

Question 30

What will happen to the AP if either stick shacker activates

Answer 30

It will automatically disconnect.

Question 31

Answer 31

1) Prevent Stall
2) Prevent Descent
3) Prevent Overspeed

Question 32

How do you conduct a stall test on the ground

Answer 32

1) Release the gust lock and pull controls aft
2) Press and Release the test button
3) Hold the control column until “push” occurs and complete.
4) Make sure light goes out.

Question 33

What is a successful indication of a stall test and what do you do if you don’t get a successful test.

Answer 33

Successful Test = Light goes out

If light does not go out then conduct the test again and if it still does not go out then write it up.

Question 34

How often must a stall test be conducted?

Answer 34

After every leg.

Question 35

What are the indications on the pitch limit indicator and what does it tell you?

Answer 35

it goes from Green to Yellow to Red as the attitude increases the shacker speeds up as approaching a stall.

Question 36

How is the AP/ Trim/YD/Pusher cutout activated

Answer 36

When the red Q/D button is pushed on the yolk, the electrical signal to each of these systems is interrupted and kicks them off line.

Question 37

What indication will you get if you encounter windshear with increasing performance. Is a mandatory Go-Around required when you get this warning?

Answer 37

Amber windshear warning on PFD with Aural warning “CAUTION WINDSHEAR”

Mandatory Go- Around is not required.

Question 38

At what height is windshear guidance terminated?

Answer 38

above 1500’ AGL

Question 39

What logic does the stall computer follow?

Answer 39

1) Prevent Stall
2) Prevent Descent
3) Prevent Overspeed

Question 40

What are the three ways windshear escape guidance can be entered?

Answer 40

1) Manually - by pressing the go-around button with any windshear
2) Automatically - when go-around or T/O mode with any windshear
3) Automatically - when the TLA is above 78° (Max Thrust) and performance decreasing shear is detected.

Question 41

What does the T/O configuration button check?

Answer 41

1) Parking Brake Off
2) Trim in the Green
