Landing Gear and Brakes Flashcards
When is alternate braking available?
Any time normal brakes are not active
Which hydraulic system is used for normal braking?
GREEN
When braking without anti-skid (BRK A/SKID switch selected to
ALTN/OFF) the BRAKES indicator should be monitored to limit
brake pressure to what psi?
1,000 psi
Green hydraulic system pressure is not available and ALTN/ON
is selected on the BRK A/SKID panel. Prior to landing, which
AUTO BRK system should be selected?
NONE
Which AUTO BRK system is normally armed for takeoff?
MAX
What speed must be achieved during takeoff to automatically
apply the selected AUTO BRK mode during a rejected takeoff?
85 KTS
When the aircraft is being towed, which Nose Wheel Steering
controls are available?
No steering controls are available from the flight deck
What temperature on any brake will cause the amber BRK
HOT light on the LDG GEAR panel to illuminate?
> 300C
Via what two components is braking achieved?
Brake pedals or AUTO BRK system
Which hydraulic system is used when normal brakes are not
available?
YELLOW
Both generators fail in-flight. The standby generator fails to
automatically start. Which switch can manually start the
standby generator?
STBY GEN
When is the anti-skid system deactivated?
ALTN/OFF is selected on the BRK A/SKID panel
With the aircraft in approach or landing configuration, what is
indicated when the red arrow on the Landing Gear Control
panel is illuminated?
Landing gear are not down and locked
An interlock mechanism prevents unsafe gear retraction until
the aircraft is in what configuration?
Three shock absorbers extended, nose wheel centered and
two main bogie beams aligned
During normal operations, when is hydraulic pressure
removed from the nose wheel steering system?
Nose gear shock absorber extended, towing lever selected to
ground tow, or both engine fuel levers selected to OFF
Which gear have brakes and A/SKID?
Main gear only
In what position must the gear handle be to arm the
autobrakes?
The DOWN or OFF position
How does the Normal anti-skid system prevent MLG wheel
lock/skidding?
It compares each pair of MLG wheels to the nose wheel
rotation
How is aircraft directional control maintained after landing
with a Green hydraulic system failure?
Using rudder pedals and differential braking
What is a way to disarm the autobrakes after landing?
Apply sufficient force to the brake pedals
What is a difference between LO and MED Auto Brake settings?
LO – 8 sec delay, MED – immediate application
What activates Auto Brakes?
The ground spoiler extension command
How may the autobrakes be monitored for proper operation?
The green flow bars on the switch will illuminate when
aircraft’s rate of deceleration matches the mode selected
An interlock system prevents unsafe gear retraction until the
aircraft is in what configuration?
Weight off wheels, nose wheel centered, and both main bogie
beams aligned
How is the landing gear extended with a Green hydraulic
system failure?
Manually, using a gravity extension procedure
Which wheels have anti-skid protection?
All eight MLG wheels
When are autobrakes not available?
When using the Alternate brake system
