• Hydraulically actuated mechanical locks.

8

Which of the following is true regarding gear down and locked sequence?
• Mechanical linkage unlocks the uplocks, gear falls with hydraulic assist, gear doors close via mechanical linkage.
• Electric motor unlocks the uplocks, gear falls by gravity, hydraulic pressure closes the gear doors.
• Hydraulic pressure unlocks the uplocks, lowers the gear, and closes the gear doors.
• Hydraulic pressure unlocks the uplocks, gear falls by gravity, hydraulic pressure closes the gear doors.

• Hydraulic pressure unlocks the uplocks, gear falls by gravity, hydraulic pressure closes the gear doors.

9

The landing gear speed limits for all configurations and modes are ____

• 280 / .80
• 270 / .82
• 275 / .87
• 285 / .85

• 270 / .82

10

Following landing gear retraction, with switches in the ON position, the Nose Gear Landing and Taxi lights:
• extinguish as soon as retraction begins.
• Sequence off after a 2 minute delay.
• Dim to a very low wattage to conserve bulbs.
• Remain ON to illuminate the wheel well in case a visual inspection is required.

• extinguish as soon as retraction begins.

11

Hydraulic power for gear retraction and extension is supplied by the:
• Auxiliary hydraulic system.
• Right hydraulic system.
• Left hydraulic system.
• Center hydraulic system.

• Center hydraulic system.

12

Wheel brake temperatures are displayed:
• As a status message.
• On the hydraulic synoptic.
• On the gear synoptic.
• Only at the tire valve.

• On the gear synoptic.

13

After retraction, the landing gear are held up by:
• Center system hydraulic pressure.
• Electrically activated gear pins.
• Uplocks.
• The landing gear doors.

• Uplocks.

14

If an RTO is initiated below 85 knots groundspeed, the RTO autobrake function:
• Does not operate.
• Operates in the minimum function.
• Operates in the moderate function.
• Operates in the maximum function.

• Does not operate.

15

Which of the following will disarm the Autobrake system and cause the EICAS "AUTOBRAKES" advisory message to display?
A. Selection of the Autobrake switch to Disarm.
B. Autobrake system is inoperative for any reason.
C. RTO is initiated above 85kts but autobraking has not been applied.
D. All of the above.

17

What does the alternate landing gear extension system use to extend the gear?
• A dedicated DC hydraulic pump and trapped center hydraulic system fluid.
• A reserve hydraulic booster to open the doors.
• A pneumatically powered pump to open the gear doors.
• Individual mechanical release handles

• A dedicated DC hydraulic pump and trapped center hydraulic system fluid.

18

What is provided by the RTO function of the autobrake system?
• The RTO function automatically applies the maximum programmable
deceleration rate when the thrust levers are retarded to idle above 65 knots.
• The RTO function automatically applies maximum brake pressure when the thrust levers are retarded to idle above 65 knots.
• The RTO function automatically applies maximum brake pressure when the thrust levers are retarded to idle above 85 knots indicated airspeed.
• The RTO function automatically applies maximum brake pressure when the thrust levers are retarded to idle above 85 knots groundspeed.

• The RTO function automatically applies maximum brake pressure when the thrust levers are retarded to idle above 85 knots groundspeed.

19

If center hydraulic system fluid quantity is low, is it likely that the gear actuation system has lost all available pressure sources?
• Yes, If center hyd system fluid quantity is low, the alt. extension system has lost all available pressure sources.
• No, if center hydraulic system fluid quantity is low, the C1 demand pump is isolated from the center hyd sys to provide a nosewheel steering source.
• Yes, if center hydraulic system fluid quantity is low, the alternate gear actuation levers must be used.
• No, if center hydraulic system fluid quantity is low, the C1 primary pump is isolated to provide an alternate extension pressure source.
