Landing Gear & Brakes Flashcards
What does pulling the LANDING GEAR FREE FALL
LEVER do?
Relieves the hydraulic pressure in the landing
gear lines and mechanically releases the uplock
hooks for all the landing gear (AOM 9-13-30)
What does it mean when the LANDING GEAR
POSITION INDICATIONS turn to red icons?
That more than 20 seconds has passed since
a discrepancy has been detected between the
landing gear lever position and the actual landing
gear position (AOM 9-13-30)
If the parking brake is not fully released on the
ground, what CAS message will be displayed?
Either a white PARKING BRAKE ON CAS or a
cyan CHECK PARKING BRAKE CAS message
(AOM 9-13-30)
If the parking brake is not fully released in flight,
what CAS message will be displayed?
An amber PARK BRAKE NOT REL CAS message
AOM 9-13-30
Where can the emergency/park brake accumulator
pressure and the brake temperature indications
be seen?
On the STATUS synoptic pages (AOM 9-13-30)
How long can the light on the STEERING button
and the STEERING DISC CAS message take to go
off after the first engagement of the nose wheel
steering?
Up to 2 seconds (AOM 9-13-30)
Which steering switch has priority for safe operation
on the ground?
The external STEERING DISENGAGE switch
AOM 9-13-30
When will the green TOWING ALLOWED light in
the external steering panel illuminate?
When the external STEERING DISENGAGE
switch is in the DISENGAGE position and the
parking brake is not applied (AOM 9-13-30)
How far should the airplane be towed slowly in a
straight line before turning?
3 m (10 ft) (AOM 3-01-75)
When should the DN LCK REL (downlock release)
button be used?
Only in the event of a landing gear control lever
failure or when it is necessary to clear obstacles
(AOM 9-13-50)
What type of brake system is on the aircraft?
Brake-by-wire (AOM 9-13-60)
During normal operations, what does the Brake Control Unit (BCU) provide?
Locked wheel protection, anti-skid protection,
gear retract braking, touchdown protection, a
gear extension test, brake temperature monitoring,
and autobrake (optional) (AOM 9-13-60)
Where can the Brake Temperature Monitoring
System (BTMS) information be found and what
does it provide?”
On the STATUS synoptic page; brake temperature
status on the synoptic page and brake
overheat warning on the EICAS (AOM 9-13-60)
Where must the brake temperature indication be
prior to takeoff?
In the green range (AOM 3-15)
What are the two different modes of AUTOBRAKE
control?
Landing mode (LO, MED, HI) and rejected takeoff mode (RTO) (AOM 9-13-60)
What kind of pressure will autobrake in the RTO
mode apply?
A brake pressure equivalent to maximum manual
braking (AOM 9-13-60)
When will autobrake applications begin on landing?
Autobrake application will start 1 second
after WOW indicates ground and thrust lever
signal at idle (AOM 9-13-60)
Is antiskid protection available while braking with
the emergency/parking brake?
No (AOM 9-13-60)
What handle position is used when using the
emergency/parking brake as a parking brake?
The handle must be pulled until it locks at the
full up position (AOM 9-13-60)
Where can the emergency/parking brake handle
be set to as a reference for emergency braking?
To the intermediate position (first detent)
AOM 9-13-60
How can the emergency/parking brake be modulated?
By keeping the release button pressed
AOM 9-13-60
How many full applications/how many hours of
parking do the emergency/parking brake accumulators
provide?
6 or 16 (AOM 9-13-60)
When the airplane is airborne, is the steering
system engaged?
No, it will be automatically disengaged
AOM 9-13-70
What is the maximum range that the nose wheel
can turn in free wheel steering mode?
±170 degrees (AOM 9-13-70)
List the steering angles and associated speed
with nose wheel steering engaged:
Steering angle varies from ±62 degrees up to 10
kts, decreasing linearly to ±8 degrees at 25 kts
and then to ±3 degrees at 68 kts (AOM 9-13-70)
What airspeed is VLO?
250 kts (AOM 2-10)
What airspeed is VLE?
250 kts (AOM 2-10)
When must AUTOBRAKE be set to OFF?
For emergency and abnormal procedures
AOM 2-49
