The Auto Brakes system will provide automatic braking down to ___ kts groundspeed if not disarmed by the pilot
Zero
Following touchdown with Auto Brakes armed, when will the auto brakes activate?
When both thrust levers are at idle
Which of the following disarms the autobrakes after landing?
Both (Manual braking and retracting the speedbrakes)
When will the AUTO BRAKES light be illuminated?
When the selector is in the DISARM position

True
What is indicated with the ANTISKID message and ANTISKID light on?
Power loss or system malfunction
When does the Landing Gear lever lock prevent movement of the landing gear lever to the UP position?
When the gear is not tilted
What is the function of the landing gear lever lock?
Prevents moving the gear lever to UP on the ground
When will the landing gear lever lock release?
When the main gear tilt
What hydraulic system powers the normal brake system?
RIGHT
What hydraulic system powers the alternate brake system?
CENTRE

How does the LOCK OVRD p/b override the landing gear lever lock?
Manually
During maximum braking what prevents the wheels from skidding?
Antiskid valves
In cruise you lose complete electric power and your battery power is depleted. Can you lower the gear?
Yes, by normal extension which is unaffected by electrical power
L HYD SYS PRESS + R HYD SYS PRESS on the EICAS. Will you have nose wheel steering after touching down?
Yes
After a loss in the CENTRE hydraulic, RIGHT hydraulic and reserve brake sources, do you have antiskid braking?
No
Why is the landing gear lever moved to OFF prior to alternate gear extension?
To prevent the possibility of hydraulic power interference
The landing gear lock prevents movement of the landing gear lever to the UP position when any main gear is not tilted.
True
Pressurization of the alternate brake system occurs automatically when RIGHT hydraulic system pressure is low.
True
Inflight, what occurs the GEAR NOT DOWN configuration warning to occur?
Below 800 feet, any gear not down and either thrust lever at idle
Which one of the following will cause a takeoff configuration warning?
Parking brake set

True
There is a speed / drag limitation if the tailskid remains extended.
False
