On the ground, the LDG GEAR handle is prevented from movement to de UP position by: A) Mechanical detents. B) A spring-loaded locking solenoid. C) Hydraulic pressure. D) A manually applied handle locking device.
The landing gear uplock mechanisms are: A) Mechanically held engaged by over-center springs. B) Hydraulically disengaged normally; or pneumatically released in an emergency. C) Electrically engaged and disengaged. D) A and B.
Landing gear downlocks are disengaged: A) When hydraulic pressure is applied to the retract side of the gear actuators. B) By action of the gear squat switches. C) By removing the external downlock pins. D) By mechanical linkage as the gear begins to retract.
Each main gear wheel incorporates a fusible plug that: A) Blows out if the tire is overserviced with air. B) Melts, deflating the tire if and overheated brake creates excessive tire pressure. C) Is thrown out by centrifugal force if maximum wheel speed is exceeded. D) None of the above.
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 three green lights out. D) All four lights out.
The gear warning horn cannot be silenced when one or more gear are not down and locked and: A) Flaps are extended beyond the 15° position. B) Airspeed is less than 150 KIAS. C) Either throttle is retarded below 70% N2 rpm. D) Both throttles are retarded below 70% N2 rpm and airspeed is greater than 150 KIAS.
When the LDG GEAR handle is positioned either UP or DOWN: A) The hydraulic system bypass valve is energized open. B) The bypass valve is energized closed. C) The bypass valve is not affected. D) The HYD PRESS annunciator light goes out.
Emergency extension of the landing gear is accomplished by actuation of: A) 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) Two manual controls, one to mechanically release the uplocks, the other to apply air pressure for gear extension and downlocking. D) None of the above.
Nosewheel 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.
The power brake valve is actuated: A) Direct mechanical linkage from the rudder pedals. B) Mechanically by the emergency airbrake control lever. C) Hydraulically by master cylinder pressure. D) Automatically at touchdown.
Do not actuate the brake pedals while applying brakes with the emergency brake system because: A) Air bubbles will be induced into the brake fluid. B) The shuttle valve may allow air pressure into the brake reservoir, rupturing it or causing uncommanded differential braking. C) The shuttle valve will move to the neutral position and no braking action will occur. D) The brakes will be “spongy”.
The DC motor-driven hydraulic pump in the brake system operates: A) During the entire time the LDG GEAR handle is in the DOWN position. B) As needed with the LDG GEAR handle DOWN in order to maintain system pressure. C) Only when the LO BRK PRESS annunciator illuminates. D) Even when the LDG GEAR handle is UP to keep air out of the system as the airplane climbs to altitude.
Regarding the landing gear, the correct statement is: A) The red GEAR UNLOCKED light will illuminate and the warning horn will sound whenever either or both throttles are retarded below 70% N2 and the gear is UP. B) The gear warning horn can be silenced when the gear is not down and locked and the flaps are extended below 15°. C) The landing gear pins must be inserted on the ground due to loss of hydraulic pressure as the engine are shutdown. D) The landing gear is secured in the extended position by mechanical locks in each gear actuator.
Regarding landing gear auxiliary extension, the correct statement is: A) If three lights are observed after yawing the airplane, it is not necessary to use the pneumatic bottle. B) The optimum airspeed for this procedure is 170 to 190 KIAS. C) The LDG GEAR handle is placed in the DOWN position to release the gear uplocks in order to allow the red T-handle to release the doors. D) After the gear are extended by this procedure, they can be retracted in flight if the hydraulic system is returned to normal operation.
