Landing Gear and Brakes Flashcards
(26 cards)
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
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
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
If the parking brake is not fully released in
flight, what CAS message will be displayed?
An amber PARK BRAKE NOT REL CAS message
Where can the emergency/park brake accumulator pressure and the brake temperature indications be seen?
STATUS synoptic pages
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
Which steering switch has priority for safe
operation on the ground
The external STEERING DISENGAGE switch
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
How far should the airplane be towed slowly in a straight line before turning?
10 ft
When should the DN LCK REL (down lock
release) button be used?
Only in the event of a landing gear control
lever failure or when it is necessary to clear obstacles
What type of brake system is on the aircraft?
Brake-by-wire
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
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
Where must the brake temperature indication be prior to takeoff?
In the green range
What are the two different modes of AUTOBRAKE control?
Landing mode (LO, MED, HI) and rejected
takeoff mode (RTO)
What kind of pressure will autobrake in the RTO mode apply?
A brake pressure equivalent to maximum
manual braking
When will autobrake applications begin on
landing?
Autobrake application will start 1 second after WOW indicates ground and thrust lever signal
at idle
Is antiskid protection available while braking with the emergency/parking brake?
No
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
Where can the emergency/parking brake
handle be set to as a reference for emergency braking?
To the intermediate position
How can the emergency/parking brake be
modulated?
By keeping the release button pressed
How many full applications/how many hours of parking do the emergency/parking brake accumulators provide?
6 or 16
When the airplane is airborne, is the steering system engaged?
No, it will be automatically disengaged
What is the maximum range that the nose
wheel can turn in free wheel steering mode?
±170 degrees
