Q

Recall how to determine if parking brake pressure is low:

A

Brake Pressure as depicted on the Configuration SD
 White - Normal range
VOL. 2
14.10.4 50
 Amber – If below a predetermined low-pressure limit. Value is boxed.
 BRAKE PRES LO (CONFIG) - One or both brake accumulator pressures
are low

Q

Recall primary and secondary gear indications:

A

Gear Lights (LEFT, NOSE, RIGHT)
 Green - Landing gear is down and locked.
 Red - Respective landing gear is not locked in position corresponding to
position of gear handle.
Secondary Gear Indications (CONFIGURATION SD)
 White - Landing gear is up and locked.
 Green - Landing gear is down and locked.
 Red - Indicates one of the following:
- Landing gear is not down and locked and gear handle is down.
- Landing gear is in transit or not in agreement with gear handle.
- Any unsafe gear condition exists.
 Green and Red - Disagreement in position indicators or ANNUN LT TEST
Switch has been depressed.

Q

Explain the function of the ANTISKID system:

A

Each brake system incorporates an anti-skid feature to allow maximum
wheel braking without skidding the tires.
 The anti-skid system also provides touchdown protection in flight, which
prevents brake application until after wheel spinup
.
 At low taxi speeds, the anti-skid system is automatically disabled to allow
manual braking.
 The anti-skid system is tested automatically whenever power is applied.
When a malfunction occurs, an associated anti-skid alert is displayed.

Q

Recall how braking is affected with a loss of both hydraulic systems:

A

Each main gear wheel is equipped with disc-type brakes operated by two
VOL. 2
14.20.3 51
independent hydraulic brake systems. Both hydraulic brake systems power
each brake assembly. The systems are synchronized to simultaneously
apply the brakes.
 Each is equipped with an accumulator of sufficient capacity to provide
brake pressure to stop the airplane, should both hydraulic systems fail.

Q

Explain how nose gear steering is affected by the use of the emergency
gear extension lever:

A

When the lever is raised, the right hydraulic system is isolated from the
landing gear. As a consequence, nose gear steering is restricted to the left,
even when both hydraulic systems are operating

Q

Recall the conditions which will allow the aural gear warning horn to be
silenced by pushing the GEAR HORN switch

A

GEAR HORN Button – Push: Silences landing gear warning horn and vocal
warning except when gear is not down and flaps are extended for landing; gear
must be down and locked to silence the warning.

Q

Recall how brake temperatures are depicted:

A

Brake Temperatures on the Configuration SD
Indicates a relative value of wheel brake temperature:
 White - Normal range
 Amber - Exceeds temperature limits. Value is boxed.
NOTE: After landing, brake temperature differential up to 60°C on the same
gear is considered normal

Q

Recall that the ANNUN LT TEST button also tests the gear unsafe
condition:

A

When the ANNUN LT TEST button is pushed, a warning horn and a voice
warning will sound to alert the crew of a gear unsafe condition.
