Landing Gear, Brakes, Nosewheel Steering Flashcards
How many Proximity Sensor Electronic Modules process signals from weight on wheel sensors to determine WOW status?
2
How many WOW sensors are installed on each gear?
2
There are a total of _______ WOW sensors on the aircraft.
6
Hydraulic pressure for the landing gear system is delivered by Hydraulic System #_______.
2
The landing gear indication will be displayed in _______ when the gear is down
and locked.
green
True or False: In the event of dual radio altimeter failure, the landing gear warning inhibition button silences the aural warning only if the SLAT/FLAP lever is in the 0,1,2,3,4 position.
True
The nosewheel steering system is powered by Hydraulic System #_______.
2
The nosewheel steering system is electronically controlled and powered by
Hydraulic System #_______.
2
The maximum nosewheel deflection when using the steering tiller is _______
Degrees.
76 degrees
True or False: From 0-10 kts., maximum steering deflection is 56 degrees from
Center.
False [76 degrees]
True or False: Generally, the faster the speed on the ground, the LESS steering is available from the tiller.
True
Maximum steering deflection available above 100 kts. is _______ degrees.
+-7 degrees
True or False: The brake system automatically applies the brakes upon gear
retraction to stop the wheels from spinning as they retract
True
True or False: The braking system is a “brake by wire” system.
True
If a wheel’s speed is _______ below its paired wheel, the BCM commands zero
pressure to the brake of the slower wheel.
33%
Anti-skid protection is deactivated at speeds below _______ kts.
10 kts
True or False: Anti-skid protection is available when using the emergency brake.
False
The touchdown protection system, which prevents operation of the main landing gear brakes during touchdown, will inhibit braking until _______.
3 sec. after WOW is sensed or wheel speed is above 50 knots
When in the normal operating range, the brake temperature pointer and digital brake temperature values are displayed with which color?
green
When brake temperature has reached the cautionary range or no takeoff range, it is displayed with which color?
amber
True or False: In terms of brake temperature, if a value is invalid, the pointer
disappears from the display and the digital display changes to amber dashes.
True
Autobrakes are provided for _______.
Both landing and rejected takeoffs
_______ is the selected autobrake mode for takeoff, providing maximum
deceleration rate.
RTO
The Emergency/Parking brake can be used to slow the aircraft when the normal braking system has failed and is powered by Hydraulic System #_______ and
#_______.
1, 2
