Landing Gear Flashcards
Which hyd system powers the landing gear system?
Center
What are the different types of braking options available?
Normal, alternate, reserve
Which hyd system powers normal brakes?
Right
Which hyd system powers the alternate brakes?
Center
Which system powers the reserve brakes and nose wheel steering system?
Center system
What holds the gear up?
The wheel well doors hold it once the system is depressurized
What holds the gear down?
Drag brace
Which air ground system controls the lever lock?
The tilt system
Which are two air ground sensor systems available?
The tilt system and nose gear strut compression sensor
What do you do if the lever lock did not de energize after takeoff?
You push the override and raise the gear
Do you get antiskid protection in alternate and reserve brake systems?
Yes
Do you have anti skid protection if you are down to brake accumulator pressure?
Yes..
How do the plane stop main wheel rotation as the gear is raised up?
It automatically applies break pressure.
The nose wheel stops using a snubber in the wheel well.
How does alternate gear extension work?
An electric motor trips the locking mechanism for each gear
Does the tail skid come down with alternate extention?
No
When does alternate brakes kick in automatically?
When it senses the right hyd system pressure is low
How do you activate the reserve brake system?
Press the switch
Can you get rto if you have anti skid inop?
No
What speed does rto activate?
85 kts
Thrust levers idle
When does auto brake activate on landing?
With the auto brakes system armed and both thrust levers at idle, automatic braking is initiated at touchdown when main landing gear truck untilt and wheel spinup occur
Whats happens to rto switch upon liftoff?
It trips off
What is the primary use of reserve brake system?
For nose wheel steering
What does the brake source light mean?
The BRAKE SOURCE light indicates that both normal brake system pressure (right hydraulic sys-tem) and alternate brake system pressure (center hydraulic system) are low.
When does brake temps become in white box and white letter?
5
When does brake temp become in a white box?
