Landing Gear and Brakes Flashcards
What does pulling the landing gear freefall lever do?
Relieves the HYD 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 indicators 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 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.
If the parking brake is not fully released in flight, what CAS message will be displayed?
Amber PARK BRAKE NOT REL cas.
Where can the emergency/ park brake accumulator pressure and the brake temp 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.
up to 2 seconds.
Which steering switch has priority 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 an landing gear failure when necessary to clear obstacles.
What type of brake system is on the aircraft
Brake By wire.
During normal ops, what does the Brake Control Unit (BCU) provide
1) Lock wheel protection
2) Anti Skid protection
3) gear retract braking
4) Touchdown protection
5) a gear extension test
6) brake temp monitoring
7) Auto-braking
Where can the Brake Temp Monitoring System (BTMS) information be found and what does it provide
On the STATUS synoptic page, brake temp status on the synoptic page and brake overheat warning on the EICAS.
Where must the brake temp indication be prior to TO
in the green range.
What are two different modes for AUTOBRAKE
1) Landing Mode (LO, MED, HI)
2) Rejected TO (RTO)
What kind of pressure will autobrake in the RTO mode apply.
A brake pressure equivalent to max manual braking.
When will AUTOBRAKE applications begin on landing
One second after WOW indicates ground and TL signal at idle.
Is antiskid protection available when braking with the emergency/ parking brake
No
What handle position is used when using the emergency parking brake as a parking brake
Pulled until is locks in 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, will be steering system engage?
No, it will automatically be disengaged.
What is the maximum range that the nose wheel can turn in free wheel steering mode
+- 170 deg
List the steering angles and associated speed with nose wheel steering engaged
Steering angle varies from +-62 deg up to 10 kts, decreasing laterally to +-8deg at 25 kts and then to +-3 deg at 68 kts.
