Systems - Crew Awareness Flashcards
How are most systems on the EMB145 commanded and what are the exceptions?
Most are commanded electrically, with the following exceptions:
1) Flight Control Disconnects (Elev and Ailerons) - Mechanical
2) Parking Brake - Mechancical
3) Landing Gear Lever Lock (red button)
4) Manural Pressurization Knob - Needle Valve
5) Gear Free Fall Handle - handle
What will be displayed if you experience a loss of signal or invalid signal?
Red Xs or Amber Dashes.
What will be displayed on the screens if there is a loss of data? What if there is a Failed Tube or loss of power?
Loss of Data - Red X
Failed Tube/ Loss of Power - Screen Black.
What is the order that EICAS messages are presented?
Order of severity by color group (Red, Yellow, Blue) and by order of recency within that color group (most recent on top).
What are the exterior dimensions of the EMB-145
Height: 22ft 2 inches
Length: 98 feet
Wingspan: 65 ft 9 inches.
What is the turning radius of the nose pedals on each side? What is the turning radius of the tiller on the captains side?
Both pilots have 5° NW steering with pedals
Capt has an additional 71° with tiller for a total of 76°
What considerations should be taken when operating the pilot seats on the ground?
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).
How should you respond to a TCAS RA
1/4 to 1/2 G maneuvers (Gentle) in accordance with the RA advisory (get the VSI needle in the Green).
How should you react to a EGPWS advisory
Max power and Climb (Max Performance Climb).
What is the function of the IC600s
Send display signal images to the PFDs, EICAS and MFDs.
What are DAUs
Data aquisition units - send data to the IC600s
What is DAU 1, what is it dedicated to and what happens if it fails
It is the primary channel, dedicated to FWD systems & Eng 1. If fails you will get an EICAS message and amber dashes.
What is DAU 2, what is it dedicated to and what does it do if DAU 1 goes off line.
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.
What displays do the #1 and #2 IC600 respectivly provide images to?
IC600#1: PFD1, MFD1 & EICAS
IC600#2: MFD2, PFD2
What happens to the displays if either IC-600 fails. How do you get cross side data
1: PFD1, MFD1 and EICAS will get Red Xs
- If either IC600 fails, push reversionary panel button to get cross side data.
What problems may exist if a display screen goes dark?
- Dimmer Switch may be on
- Failed Tube
- Electrical Failure/ Loss of power to tube.
What are the power sources for various screens?
- DC1 powers: PFD1, MFD2
- DC2 powers: MFD1, PFD2, TBCH
- Essential 1 powers: RMU1, EICAS
- Essential 2 powers: RMU2
During an IC600 level 1 test, what should you see?
- Big Blue Ball on attitude indicator
- Red Xs on Airspeed and Altimeter
- Amber Dashes on numerical values.
What consideration should you consider when conducting the IC600 level 2 test
All items will pass reletivly quickly and in sequence, but Radio Altimeter takes a longer time to pass (keep pushing button until each passes).
How long does it take for Blue ICAS messages to stop flashing after being displayed
After 5 seconds.
How will EICAS messages in excess of 15 be displayed, and how do you access them?
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.
What is the purpose of takeoff and landing inhibition logic?
to eliminate neusance messages that might cause a distraction to pilots when close to the ground (pretty much all messages are considered neusance).
When is takeoff inhibition logic valid from and to?
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.
When is landing Inhibition Logic Valid From and To
Valid from RA of 200ft agl to:
1) Weight on Wheels + 3 secs
2) After 1 min if you go around.
How do you deal with CAS messages (non EICAS)?
Go to Message Miscomparison checklist in the QRH and follow the associated checklist.
What Aural warnings will be sounded if the Aircraft is not properly configured for T/O
Flaps
Trim
Brakes
Spoilers
What are the elements of the stall system
1 stall computer with 2 channels
2 stick shakers
1 stick pusher
Which side (Captain or FO) is the stick pusher control attached
Captains side cable run
When will the stick pusher not push
1) Above 200 kts
2) Below 200 ft
3) Below 1/2 G
4) If holding down the AP quck disconnect (elec signal interrupt)
5) If only on one computer channel (other is inop or de-selected).
6) On the ground except in TEST.
What will happen to the AP if either stick shacker activates
It will automatically disconnect.
What is the “logic” of the stall computer
1) Prevent Stall
2) Prevent Descent
3) Prevent Overspeed
How do you conduct a stall test on the ground
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.
What is a successful indication of a stall test and what do you do if you don’t get a successful test.
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.
How often must a stall test be conducted?
After every leg.
What are the indications on the pitch limit indicator and what does it tell you?
it goes from Green to Yellow to Red as the attitude increases the shacker speeds up as approaching a stall.
How is the AP/ Trim/YD/Pusher cutout activated
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.
What indication will you get if you encounter windshear with increasing performance. Is a mandatory Go-Around required when you get this warning?
Amber windshear warning on PFD with Aural warning “CAUTION WINDSHEAR”
Mandatory Go- Around is not required.
At what height is windshear guidance terminated?
above 1500’ AGL
What logic does the stall computer follow?
1) Prevent Stall
2) Prevent Descent
3) Prevent Overspeed
What are the three ways windshear escape guidance can be entered?
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.
What does the T/O configuration button check?
1) Parking Brake Off
2) Trim in the Green
3) T/O Flaps
4) Spoilers Closed.
