What does the Auto-brakes Disarm position do
Disarms the system
Releases brake pressure
What does the Auto-brake selector at RTO do
Automatically applies Max brake pressure when
Thrust levers idle at +85kts
What does the BRAKE SOURCE light mean when illuminated
Normal and Alternate brake system pressure low
Which Hydraulic systems powers Normal braking
R HYD system
Which Hydraulic system powers alternate braking
The C HYD system
Is Autobrake available with the Alternate braking system
No
How are the Nose/Main gear held up
Nose held up by uplocks
Main held up by door structure
What does the OFF position on the landing gear do
Depressurizes landing gear system
What does pressing RESERVE BRKS & STRG switch provide
It provides fluid to the C Hyd Pump 1.
Pump pressure is provided exclusively to the alternate brake system and N/W steering
Purpose of Brake Accumulator
If Normal and Alternate Brake system power is lost it can provide several braking applications
When does Auto-brake application begin
Both Thrust Levers are retarded to Idle
Wheel spin-up
What 3 actions happen when the autobrake system disarms on the ground
Auto-brake selector moves to Disarm
Power removed from Auto-brake system
Auto-brake light illuminates
Which Hydraulic system powers the Normal Brake system
The Right Hyd System
When does the Alternate Brake system activate
Automatic
When the R Hyd system is low
What does the illumination of the BRAKE SOURCE light mean
Both Normal and Alternate brakes system pressure are low
What does pressing the RESERVE BKS & STRG switch
It provides Hydraulic fluid to the C1 electric primary pump
It then supplies pressure exclusively to the alternate braking system and N/W steering
Purpose of Brake Accumulator
Provides several brake applications when Normal/Alternate/Reserve braking fails
When is Anti-skid protection available
Only during Normal and Alternate braking
When does each wheel have individual anti-skid protection
Only when Normal brake system available
Is Anti-skid available during Alternate braking
Yes, to Laterally paired wheels
Can the parking brake be set while on Alternate or Reserve brakes
Yes
What functions disarms the Autobrakes
F - fault S - stowing Speedbrakes T - Thrustlevers forward O - off P - Pressing the Pedals
