|
|
|
Moving the landing gear lever to the OFF position does what? |
Hydraulic power is removed from the landing gear system |
|
|
|
Is manual gear extension possible with no hydraulic A system pressure? |
Yes |
|
|
|
What conditions causes the RTO braking to engage? |
When thrust levers are moved to idle at or above 90 knots **Ground spoilers for RTO will not deploy until Reverse TL are positioned for reverse thrust. This is the reason we move speedbrake handle to UP during RTO manoeuvre. |
|
|
|
How do you know the parking brake is set? |
The red light will illuminate |
|
|
|
Rudder pedals provide how much nose gear deflection? |
7 degrees |
|
|
|
The tiller rotates the nose wheel how many degrees? |
78 degrees |
|
|
|
Is Autobrakes available with both normal and alternate Brakes? |
No, just normal brakes |
|
|
|
Is antiskid provided on Normal and Alternate braking systems? |
Yes and accumulator braking |
|
|
|
How is the landing gear held in the up position? |
Uplocks |
|
|
|
If both A and B systems are lost is it possible to use brakes? |
Yes, the accumulator provides limited braking applications |
|
|
|
How do you check hydraulic quantity and pressure? |
SYS page on the MFD System switch |
|
|
|
What has happened if the A or B LOW PRESSURE lights illuminate on the flight control panel? |
Low pressure is sensed to the Ailerons, Rudder and Elevator in either system |
|
|
|
Where is the hydraulic pressure of the accumulator shown? |
Hydraulic Brake pressure indicator on the FO side |
|
|
|
What system pressurises the Brake Accumulator? |
System B |
|
|
|
How do you know the RTO Autobrake self test was successful? |
When selecting RTO on the ground a self test is completed. While that test is being completed the DISARM light illuminates for 1-2 seconds. When that light extinguishes the self test is complete. |
|
|
|
Does the Autobrake do a landing turn on self test? |

System B engine driven pump Hydraulic pressure drops below limits Airborne Flaps are less than 15 but not up |
|
|
|
What Hydraulic system normally pressurizes the Autoslats and LE Devices? If fluid volume is lost what occurs? |
