What do the wing tip breaks do?
Lock the slats or flaps in case of uncommanded movement, overspeed, asymmetry or runaway.
If the ND fails can it be transferred?
Yes, using the PFD/ND transfer button.
IF an SD button fails can you still view the system page?
Yes, using the ALL button.
What are the red CB’s for?
Wing tip breaks and can not be reset by the flight crew.
How is an armed mode shown?
In blue.
How is a managed mode shown?
In magenta.
How is an active mode shown?
In green.
How many times can you attempt to start the APU?
Three times, then a period of 60 minutes is required before attempting another start.
What does the APU low oil level message mean?
The APU can be used for another 10 hours of continuous operation.
What is the GEN 1 line used for?
Smoke configuration.
How many channels does a slat/flap computer have?
Two, slat and flap.
What does a half-box over the oxygen indication mean?
The pressure is at 1500PSI or less.
What does the EXTRACT override button do?
Puts the avionics ventilation system into a closed circuit.
Below what temperature will the avionics run in a closed circuit?
9 degrees on the ground and 35 degrees in the air.
When would you set the BLOWER and EXTRACT fans to override?
When smoke configuration is required.
When do we activate the approach by?
The deceleration point.
Is dry cranking available during an automatic engine start?
Yes, on the ground only.
What can be powered by the emergency GEN?
AC ESS BUS, AC ESS SHED BUS, DC ESS BUS, DC ESS SHED BUS.
Can AC BUS 2 be powered by the emergency GEN?
No.
When does the PTU operate?
When there is a pressure differential of 500PSI between the two systems, and there is integrity in the receiving system. The PTU is inhibited during first engine start and when the cargo doors are operated.
What does the FWC generate?
Level 3 and 2 warnings and cautions.
What do the FACs and ELACs do?
The FACs generate the flight envelope, the ELACs keep the aircraft inside the flight envelope.
What does the emergency button on the oxygen mask do?
Provides 100% oxygen with positive pressure.
What happens if both FWCs fail?
You lose all warnings and cautions. Overspeed and stall warnings may still be operational.
IN EMER ELEC, which RMP is available?
RMP1.
What will you see on the DU in case of a DMC failure?
INVALID DATA in amber.
When is the flow set to 120% automatically?
When using APU bleed or single pack operation.
What speed will the flaps auto retract?
210kt and airspeed is limited to 250kt.
What computer controls the cabin outflow valve?
Cabin pressure controller.
Where is the TAS displayed?
Top left of the ND.
Which AP or FMGC is the master?
Number 1.
What computer generates reactive windshear?
The FACs.
What computer generates predicted windshear?
The weather radar.
When do the ground spoilers deploy on a RTO?
At or above 72kt and they will activate the autobrakes.
Will the auto-brakes activate without ground spoilers?
Yes, when thrust reversers are deployed.
When is the windshear active?
Below 2300t. Predicted W/S cautions are given below 1500ft up to 3nm, reactive W/S warnings given below 1200ft up to 1.5nm.
