Front 1

What are the 3 levels of ECAM Malfunction Notifications?

Back 1

• Level 3: WARNINGS – Associated with the red MASTER WARN light, CRC, and require immediate action

• Level 2: CAUTIONS – Associated with the amber MASTER CAUTION light, single chime, and require crew awareness

• Level 1: ALERTS – Associated with amber E/WD message, no aural signal, and requires crew monitoring

Front 2

If simultaneous failures occur, how will they be presented to the crew?

Back 2

A Level 3 WARNING has priority over a Level 2 CAUTION, which has priority over a Level 1 ALERT.

Front 3

What types of failures are presented to the crew?

Back 3

• Independent – Failure affecting an isolated system/item without degrading other systems/items

• Primary – Failure of a system/item that affects the use of other systems/items

• Secondary – Loss of a system/item resulting from a primary failure

Front 4

Where on the E/WD would the crew find primary failures?

Back 4

On the lower left portion of the screen.

Front 5

What indication does the E/WD provide for secondary failures?

Secondary failures are displayed on the lower right portion of the E/WD and are preceded by an asterisk ( * ).

Front 6

What does the appearance of a green arrow indicate at the bottom of the E/WD screen?

Back 6

Information has overflowed off the screen and the pilot must scroll down using the CLR pushbutton on the ECAM panel.

Front 7

What does the display of T.O. INHIBIT or LDG INHIBIT indicate?

• Memo disappears after touchdown (80 knots)

Front 12

What does the boxed STS indicate when displayed on the E/WD?

Back 12

• The STATUS page holds messages other than CANCELLED CAUTIONS

• Flashes after engine shutdown to alert maintenance of any other applicable messages

Front 13

In general, when are the system pages automatically displayed on the SD?

• Display will reappear when the slats are extended

Front 15

What is the function of the two Landing Gear Control and Interface Units (LGCIUs)?

Back 15

• Provide sequencing, operation, monitoring, and indications for the landing gear.

• Provide aircraft "In Flight" or "On the Ground" signals to other aircraft systems

Front 16

What hydraulic system powers the landing gear and doors?

Back 16

Green

Front 17

If performing a gravity gear extension, what is one consideration concerning hydraulic power?

Back 17

Hydraulic power is no longer available to the landing gear system (it is bypassed).

Front 18

When does the red arrow in the LND panel illuminate?

Back 18

Below 750 feet RA, when the aircraft is in the landing configuration and the landing gear is not locked down.

Front 19

What happens if airspeed is 280 knots and the Landing Gear lever is selected DOWN?

Back 19

Nothing. A safety valve shuts off hydraulic power to the landing gear system when airspeed is above 260 knots.

Front 20

What do the red UNLK lights indicate?

Back 20

The landing gear is not locked in the selected position.

Front 21

What controls the LDG GEAR lights?

Back 21

LGCIU 1

Front 22

If LGCIU 1 fails will the lights still work?

Back 22

Yes, as long as it is still powered.

Front 23

What controls and manages all braking functions?

Back 23

The Brake and Steering Control Unit (BSCU)

Front 24

What happens when the A/SKID & N/W STRG is switched OFF?

Back 24

• Loss of nose wheel steering

• Braking is powered by the YELLOW system

• Anti-skid is deactivated

Front 25

Which hydraulic systems provide pressure to the brakes?

Back 25

• Normal brakes – GREEN

• Alternate brakes – YELLOW backed up by a hydraulic accumulator

Front 26

When do the Auto Brakes activate on landing if armed?

Back 26

When the ground spoilers deploy.

Front 27

What is the difference between LOW and MED AUTO BRK?

Back 27

• LOW – progressive pressure applied to brakes 4 seconds after ground spoilers deploy in order to decelerate the aircraft at a rate of 5.6 ft./s2

• MED – progressive pressure applied to brakes 2 seconds after ground spoilers deploy in order to decelerate the aircraft at a rate of 9.8 ft./s2

Front 28

What does the AUTO BRK green DECEL light indicate?

Back 28

Actual rate of deceleration is within 80% of the selected rate.

Front 29

What is the Takeoff setting for Auto Brakes?

Back 29

Back 30

• Airspeed above 72 knots, and

• Thrust levers at IDLE, and

• Ground spoiler extension

Front 31

What is the impact of the loss of GREEN hydraulic pressure on the Auto Brakes?

Back 31

The Auto Brake function is lost, because the aircraft is now relying on the alternate brake system.

Front 32

If on the alternate brake system, what is required in order to maintain Anti-skid function, if anything?

Back 32

At least 1 channel of the BSCU

Front 33

What would happen to the spoilers if they were not armed, but at least one engine was selected into reverse thrust?

• YELLOW system brake accumulator pressure

Front 37

Describe the procedure for the brake check prior to taxi. What is the significance of the callouts?

Back 37

• Press the brake pedals to ensure the aircraft slows, and check the brake pressure on the triple indicator is zero.

• Calling out "pressure zero" indicates the GREEN hydraulic system has taken over, and the normal braking system is operational.

Front 38

What computers feed data to the six display units?

Back 38

Three Display Management Computers (DMC)

Front 39

What do each of the DMCs normally supply?

Back 39

• DMC 1 – Captain PFD, Captain ND, "Upper" ECAM DU (E/WD), and "Lower" ECAM DU (SD)

• DMC 2 – First Officer PFD, First Officer ND

• DMC 3 – Backup

Front 40

If there are any automatic functions of the DMCs in the event of a failure, explain the automatic logic.

Back 40

If DMC 1 fails (or DMC3 if "CAPT 3" was selected), DMC 2 automatically drives the ECAM.

Front 41

What are the indications on the DUs if a DMC has failed?

Back 41

"INVALID DATA" will be displayed in the respective EFIS/ECAM display unit.

Front 42

What happens when the upper ECAM display fails?

Back 42

The E/WD automatically replaces the SD on the lower ECAM display

Front 43

If both the E/WD and SD display units fail, how can the E/WD information be displayed?

Back 43

By selecting the ECAM/ND XFR switch to CAPT or F/O

Front 44

If the UPPER DISPLAY knob is switched to OFF what will occur?

Back 44

The E/WD display would automatically transfer to the "lower" display

Front 45

With the E/WD displayed on the "lower" screen, what steps should be taken to view SD information?

Back 45

Press and hold the appropriate system button on the ECAM CONTROL panel. The information selected will be available for 30 seconds.

Front 46

What does the ALL pushbutton do?

Back 46

• Displays ALL the system pages successively in 1-second intervals when held down

• Release the pushbutton to maintain display of the selected page

Front 47

What does pressing the RCL pushbutton do?

Back 47

• Allows the flight crew to review any warning or caution messages that the CLR pushbutton or flight phase inhibition may have suppressed

• If held longer than 3 seconds, the E/WD will show any caution messages suppressed by the EMER CANC pushbutton

Front 48

If the STS pushbutton is pressed and the system has no STATUS messages, what will be displayed?

Back 48

"NORMAL" for 5 seconds

Front 49

What occurs during the Before Takeoff Flow when the T.O. CONFIG pushbutton is pressed?

Back 49

. The system simulates the application of takeoff power and checks certain systems for proper configuration

• A warning is displayed if a system is not configured properly

• "TO CONFIG NORMAL" is displayed in the TO MEMO section if the configuration is correct

Front 50

Describe the FO Preliminary Cockpit Preparation actions on the ECAM control panel.

Back 50

• HYD – check quantity

• ENG – check oil quantity

Front 51

Should the ECAM control panel fail, what functions are available as hard-wired buttons?

Back 51

CLR, RCL, STS, EMER CANC and ALL

Front 52

What does the EMER CANC accomplish?

Back 52

• Cancels the audio for warning messages (without removing any ECAM message)

• Cancels the present caution for the rest of the flight

• Calls up the STATUS page, which displays "CANCELLED CAUTION" and the TITLE of the failure

• Inhibited message can be recalled by holding RCL for more than three seconds

Front 53

What is the purpose of having the EMER CANC pushbutton?

Back 53

Used to cancel spurious MASTER CAUTIONS
