Landing Gear and 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
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 GRAKE 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?
On the status synoptic page
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 two 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 feet
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 system
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
-auto brake (optional)
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 on the AUTOBRAKE control?
Landing mode (LO, MED, HI) and rejected takeoff (RTO)
What kind of pressure will the autobrake in the RTO mode apply?
A brake pressure equivalent to the maximum manual braking
When will the autobrake applications begin on landing?
Autobrake application will start one second after WOW indicates ground and thrust levers 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 (first detent)
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 full or 16 hours
When the airplane is airborne, is the steering system engaged?
No it will automatically be disengaged
What is the maximum range that the nosewheel can turn in the free wheel steering mode?
+/- 170 degrees
List the steering angles and associated speed with nose wheel steering engaged:
-Steering angle varies from +/- 62 degrees up to 10kts, decreasing laterally to +/- 8 degrees at 25 kts and the +/-3 degrees at 68kts
What airspeed is Vlo?
250 kts
What airspeed is Vle?
250 kts
When must the AUTOBRAKE be set to OFF?
For emergency and abnormal procedures
