Landing Gear Flashcards
757: When the RESERVE BRAKES switch is activated, fluid trapped below a standpipe in the right hydraulic system reservoir is made available to the
Right system electric hydraulic pump
764: The alternate landing gear extension system uses
to release all door and gear
uplocks, and allow the landing gear to free-fall to the down and locked position.
An electric hydraulic pump
757/767: According to the graphic, the AUTO BRAKES light is illuminated because:
The autobrake system is disarmed or inoperative
767: When the RESERVE BRAKES & STRG switch is activated, fluid from the ___ is made available for reserve brakes operation.
The center hydraulic system reservoir
757/763: The PARK BRAKE light illumination on the pedestal indicates that:
The parking brake handle is not stowed
763: The alternate landing gear extension system uses ___ to trip the locking mechanism for each gear.
An electric motor
757/767: The tiller can turn the nose wheel up to ___ in either direction
65°
757/763: The landing gear lever is placed in the OFF position to:
Depressurize the landing gear system
757/767: The autobrake system disarms immediately without pilot input when:
An autobrake or normal antiskid system fault occurs
757/767: When using the alternate brake system, what antiskid protection is provided?
Alternate (paired wheel) antiskid
757: When the RESERVE BRAKES switch is activated, fluid from ___ is made available for reserve brakes operation.
Below a standpipe in the right hydraulic system
757: A white BRAKE TEMP light indicates a relative brake temperature ____ or greater exists on of one or more brakes.
5
757/767: The normal brake system is powered by the ___ hydraulic system
Right
757/767 the ____ if the RESERVE BRAKES (757), or RESERVE BKS & STRG (767) is selected and pressure is available
BRAKE SOURCE light and EICAS message extinguish
757/767: The BRAKE SOURCE light illuminates and the corresponding EICAS message displays if:
Both the normal and alternate brake system pressures are low
753/767: The TAILSKID light illuminatos and the EICAS advisory message TAILSKID displays when
The tailskid position disagrees with the landing gear lever position
767: The alternate brake system is powered by the ___ hydraulic system
Center
757/767: The alternate brake system has all the capabilities of the normal brake system except for ___, which requires that the normal antiskid system is operating.
Automatic braking
757: In the event of a total electrical failure, the landing gear can be extended:
By using normal gear extension
757/767: Limited steering control is available through the rudder pedals, allowing turns up to ___ in either direction.
7°
764: If any brake temperature is __ or more, a BRAKE TEMP EICAS message displays.
5°
757/767: Inflight and ground operation of various aircraft systems are controlled by the air/ground sensing system and the nose air/ground sensing systems. They receive logic signals from:
Tilt sensors located on each main landing gear and nose gear strut compression sensors
757/767: With the rejected takeoff (RTO) mode armed, the autobrake system applies maximum braking when:
Both thrust levers are retarded to idle above 85 knots
