320, Landing Gear Flashcards
Alternate braking WITH antiskid activates automatically following:
Failure of the Green hydraulic system
The nose wheel steering is electrically controlled and hydraulically operated by the __________ hydraulic system.
Green (basic aircraft) or Yellow (enhanced aircraft)
The main gear and doors are electrically controlled and hydraulically operated by the _________ hydraulic system.
Green
Above ______ knots, provided the ground spoilers are armed, moving the thrust levers to idle signals the flight control system to deploy the ground spoilers.
72
The two Landing Gear Control Interface Units (LGCIU 1 & LGCIU 2):
Swap roles as controlling and back up of gear extension and retraction each time the landing gear is RAISED.
The maximum indicated airspeed for gear extension is ______ knots and for gear retraction is ______ knots.
250, 220
The landing gear is controlled by ____ Landing Gear Control Interface Units, or LGCIUs.
Two
The LGCIUs send information to various systems about whether the aircraft is on ground or in flight.
T/F?
True
Braking and nose wheel steering are controlled by the _________ Unit.
BSCU
Prior to takeoff, autobrakes can be armed using the ______ pushbutton.
MAX
Autobrakes MAX is used only for takeoff.
T/F?
True
When MAX is armed, maximum auto braking is immediately applied when the ______________ signal is triggered.
Ground spoiler deployment order
For normal braking:
Green hydraulic system pressure must be available.
At least one channel of the BSCU must be operational.
The A/SKID & NW STRG switch must be selected to ON.
All of the above
All of the above
If both the Green and Yellow hydraulic systems fail, braking is still possible through a________.
Dedicated accumulator
Alternate braking is available with accumulator pressure from the ________ hydraulic system.
Yellow
