FWD INSTRUMENT|EIS ECAM SWITCHING PANELS Flashcards
What is the function of the two Landing Gear Control and Interface Units (LGCIU)?
a. Provide sequencing, operation, monitoring, and indications for the landing gear
b. Provide aircraft “In Flight” or “On the Ground” signals to other aircraft systems
When does the red arrow in the LND panel illuminate?
Below 750 feet RA, when the aircraft is in the landing configuration and the landing gear is not locked down
What happens if your airspeed is 280 knots and you place the Landing Gear lever to DOWN?
Nothing - A safety valve shuts off hydraulic power to the landing gear system when airspeed is above 260 knot
What do the red UNLK lights indicate?
The landing gear is not locked in the selected position
What controls and manages all braking functions?
a. Normal Brakes: Braking Steering Control Unit (BSCU)
b. Alternate Brakes: Alternate Braking Control Unit (ABCU)
What happens when you switch the A/SKID & N/W STRG to OFF?
a. Nosewheel steering deactivated
b. Brake pressure is supplied by the Yellow hydraulic system
c. Anti-skid is deactivated
d. BSCU and ABCU are depowered
e. A 1,000 psi pressure limiting valve helps prevent wheel lock up
Which hydraulic systems provide pressure to the brakes?
a. Normal brakes – Green
b. Alternate brakes – Yellow backed up by a hydraulic accumulator
What are the four modes of braking?
a. Normal braking
b. Alternate braking with antiskid
c. Alternate braking without antiskid (max brake pressure 1000 psi)
d. Parking brake
When do the Autobrakes activate on landing if armed?
When the ground spoilers deploy
What is the difference between LOW and MED AUTO BRK?
a. LOW – progressive pressure applied to brakes 4 seconds after ground spoilers deploy to decelerate at 5.6 FPS
b. MED - progressive pressure applied to brakes 2 seconds after ground spoilers deploy to decelerate at 9.8 FPS
What does the AUTO BRK green DECEL light indicate?
Actual rate of deceleration is within 80% of the selected rate
What is the Takeoff setting for Auto Brakes?
MAX
What will cause the MAX AUTO BRK to activate on a RTO?
a. Airspeed above 72 knots, and
b. Thrust Levers at IDLE, and
c. Ground spoiler extension
If you lose Green hydraulic pressure will you have Auto Brakes?
No, not with the Alternate Brake system
Is Anti-skid available with Alternate Brakes?
Yes, if certain conditions are met
With spoilers not armed will the spoilers deploy for an RTO?
Yes – when at least one engine is in reverse
How many brake applications are available with accumulator pressure?
Approximately 7 full applications of brake pedals or parking brake or any combination thereof
What does the BRAKES & ACCU PRESS triple indicator indicate?
a. Yellow hydraulic pressure delivered to the left and right brakes
b. Yellow system brake accumulator pressure
What computers feed data to the six display units?
3 Display Management Computers (DMC
What does each of the DMCs normally supply?
a. DMC 1 – Captain PFD, ND, upper ECAM DU, lower DU
b. DMC 2 – F/O PFD, ND
c. DMC 3 – Backup
How can you tell if a DMC has failed?
“INVALID DATA” will be displayed in the respective EFIS/ECAM display units
What happens when the upper ECAM display fails?
The E/WD automatically replaces the SD on the lower ECAM display
If both the E/WD and SD display units fail, how can you display E/WD information?
Select the ECAM/ND switch to CAPT or F/O to transfer the E/WD to either ND
With the E/WD displayed on the lower screen, how else can you view SD information?
Press and hold the appropriate system button on the ECAM Control Panel that you wish to view
What does the ALL pushbutton do?
a. Displays ALL the system pages successively in 1-second intervals when held down
b. Release the pushbutton to maintain display of the selected page
What does pressing the RCL pushbutton?
a. Allows you to recall any warning or caution messages that the activation of the CLR pushbutton or flight phase inhibition may have suppressed
b. If held longer than 3 seconds, the E/WD will show any caution messages suppressed by the EMER CANC pushbutton
If you press the STS pushbutton and the system has no STATUS messages what will be displayed?
“NORMAL” for 5 seconds
If power fails to the ECAM CONTROL panel which buttons are still functional?
a. EMER CANC
b. ALL
c. CLR
d. STS
e. RCL
What does the EMER CANC do?
a. Cancels the current Level 1 or 2 warning for the remainder of the flight.
b. Cancels the current Level 3 warning for that occurrence
What do you look for on the PRELIMINARY FLIGHT DECK PREPARATION quantity check?
a. ENG – oil quantity above 9.5 quarts + 0.5 quarts per planned flight hours
b. HYD – hydraulic quantity indexes in normal filling range
c. DOOR – oxygen pressure - if half boxed in amber, check the MIN FLT CREW OXY CHART (PRC)
What occurs when the T.O. CONFIG pushbutton is pressed?
a. The system simulates the application of T.O. power and checks certain systems for proper configuration
b. A warning is displayed if and system is not configured properly
c. “TO CONFIG NORMAL” is displayed in the TO MEMO section if the configuration is correct
