landing gear and breaks Flashcards
On the ground the landing gear handle is prevented from movement to the up position by
A. mechanical detents
B. a Spring loaded locking solenoid
C. hydraulic pressure
D. a manually applied handle locking device
B
The landing gear uplock mechanisms are
A. mechanically held engaged
B. hydraulically disengaged normally or penumatically released in an emergency
C. electrically engaged and disengaged
D. a and B
D
Landing gear downlocks are disengaged
A. when the hydraulic pressure is applied to the retract side of the gear actuators
B. by action of the gear squat switch
C. by Removing the external down lock pins
D. by mechanical linkage as the gear begins to retract
A
Each main gear wheel incorporates a fusible plug that
A. blows out if the tire is over serviced with air
B. melts deflating the tire if an overheated brake creates a create excessive tire pressure
C. is thrown out by centrifugal force if maximum wheel speed is exceeded
D. none of the above
B
At Retraction if the nose gear does not lock in the up position the gear panel light indication will be
A. Red light on green LH and RH lights on
B. red light out green LH and RH lights on
C. red light on all 3 green lights out
D. all 4 lights out
C
the gear warning horn sounds when one or more gear are not down and locked is locked and
A. Flaps are extended beyond the 15ﾟ position both throttle retracted below 70% N2
B. Airspeed is less than a 150 KIAS
C. either throttle is retarded below 70% N2 RPM
D. both throttles are retarded below 70% N2 RPM and air speed is less than 150 KIAS
A
Emergency extension of the landing gear is accomplished by actuation of
A. Is a switch for uplock release and application of air pressure
B. one manual control To release the uplocks and apply air pressure for extension
C. 2 manual controls and you’ll control one to mechanically release the uplocks the other to apply air pressure for gear extension and your extension and down locking
D. none of the above
C
Nose wheel steering is operative
A. only on the ground
B. with the gear extended or retracted
C. with the gear extended in flight or on the ground
D. none of the above
C
The power brake valve is actuated
A. mechanically by break pedal pressure XLS
B. mechanically by an emergency airbreak control lever is lever
C. hydraulically by brake pedal pressure XL
D. Automatically at touchdown
C
Do not depress the brake pedals while simultaneously using the emergency brake system because
A. manual breaking will override the airbreaks
B. the shuttle valve may allow air pressure into the brakes reservoir rupturing it or causing Uncommanded differential breaking
C. the shuttle valve will move to the neutral position and no breaking action will occur
D. the brakes will be spongy
B
The DC motor driven hydraulic pump in the brake system operates
A. during the entire time the landing gear handle is in the down position
B. as needed with the landing gear handle in the down position in order to maintain system pressure
C. only when the LO BRK PRESS annunciator illuminates
D. even when the landing gear handle is in the up position to keep air out of the system as the aircraft climbs to altitude
B
After landing gear extension the ANTISKID INOP annunciator illuminates the correct action is to
A. Use the emergency breaking system
B. Use the power brakes carefully and increase the landing distance
C. Do not use thrust reverser Do not use thrust reverse
D. Turn on ANTI SKID switch off then on annunciators annunciator stays on
B
When the landing gear handle is positioned either up or down
A. the the hydraulic system control valve is energized open
B. the hydraulic system control valve is energized closed
C. the hydraulic system control valve is not affected
D. the hydraulic press annunciator light remains out
B
During preflight you detect a fault indication on the anti-skid bite fault indicators in the nose you should
A. Contact maintenance prior to flight
B. Pull the skid control CB on the right RH CB panel
C. Consider the anti-skid system in operative and increase that take off field length
D. Reset the indication on the BITE fault indicator note the indication and continue the flight
D
During preflight you notice the nitrogen precharge on the emergency nitrogen bottle is low your action is
A. have maintenance charge the system
B. check the minimum equipment list for restrictions
C. consider that the emergency brake system may operate more slowly than expected
D. nothing as the system will pump up during engine start
A
