Landing Gear and Brakes Flashcards
What hydraulic system powers the landing gear and door
Green system
How many braking modes there is
4 braking modes
What are the braking modes
Normal, alternate with antiskid, alternate without antiskid and parking brake
A green arc appears to show
The hottest brake between 100° and does not exceed 300°
Brake arc becomes amber and temperature shows amber, and ECAM “brake hot” when
Temperature is above 300°
Green system (normal) powers
Normal braking, auto brakes, and antiskid
When green system pressure is insufficient or a failure, the automatic selector
Transfer braking system to alternate system (blue)
Does the antiskid and auto brake work on alternate system
Antiskid yes, auto brake no
Auto brake in flight
Remains active even with gear up
Blue system and accumulator provide pressure for
The alternate braking system and the park brake
The triple indicator shows
Only the alternate braking system pressure
If brake is operated with accumulator only, antiskid
Does not work (disabled)
All braking action are controlled by
A 2 channel BSCU
A momentary release indicator display when you put the gear down indicates
That the antiskid system is working normally
The release indicators display in amber if
There is a residual brake pressure during release or if there’s a fault in the brake release
The antiskid system is automatically deactivated
When the ground speed is below 10 knots
What are the 3 modes of auto brake
LO, MED and MAX
When does MAX is normally utilized
For TO
What auto brake is normally used for landing
LO and MED
Can you arm the auto brake with parking brake on
Yes
At what rate (from the selected mode) the DECEL light comes on
80%
How much time the DECEL light can take to come on
5 sec if MED and 8 sec if LOW is selected
The auto brake started to operate automatically when
Ground spoilers are commanded to extend
Auto brake LOW mode start progressive pressure application after 1 sec of spoiler deployment and target a deceleration rate of
1.8 m/s²
