Flashcards in Landing Gear Deck (36):
1
Gear Disagree mean?
Gear position disagrees with lever
2
Max speed with gear down and extension and retraction?
270kias / 0.82
3
What does moving landing gear lever to off position do?
Removes hydraulic pressure from landing gear system
4
When does gear down lights illuminate?
When gear down and locked and gear doors have closed
5
How gear and doors help up?
By mechanical uplocks
6
Where are the tilt sensors?
On main landing gear
7
What does nose air/ground sensing send signals to? (2)
- Stall warning system
- Portions of warning and caution system
8
Can you take off if AIR/GND SYS or NOSE A/G SYS indicated on EICAS?
No
9
What system removes the landing gear lever lock airborne?
Tilt sensor
10
How is gear put in tilt position when lowered?
Hydraulically
11
How many degrees for NWS via rudder pedals?
7 deg
12
Tiller turns NWS up to how many deg?
65 deg
13
How NWS, flaps, slats, and LDG gear powered if left hyd sys fails?
Right system through PTU
14
How ALT Gear work?
Main battery bus DC powers dedication electric hydraulic pump to release uplocks and gear free falls (uses fluid within supply line)
15
Normal hyd sys for brakes?
Right
16
When does alternate brakes auto come on?
When right hyd sys press is low
17
What system does alt brakes use?
Left
18
When does brake source light illuminate?
When both normal and alt brakes sys pressures are low
19
When in alt brakes what happens when brake pedals pushed?
sends hyd pressure through the alternate anti-skid valves to the brakes
20
What brake systems does the autobrakes only work on?
Only the right systems of normal and reserve brakes (as anti-skid uses normal anti-skid valves, not alternate)
21
Can the parking brake use any of the brake systems?
Yes
22
What is min brake accumulator pre-charge pressure?
1000PSI
23
What system pressurises the brake accumulator?
Right hyd sys
24
How many brake applications can the accumulator provide?
several
25
What does AUTO BRAKES light mean?
Auto brakes either disarmed or inoperative
26
When does RTO engage?
- RTO selected
- Above 85kts
- Both thrust levers are retarded to idle
27
How disengage RTO braking once initiated? (4)
- aircraft stops
- speedbrake lever stowed
- manual braking
- move selector top off
28
Whats higher on a dry runway on landing? Man braking or Max Auto?
Manual braking
29
When do autobrakes engage on landing? (2)
- both levers are at idle
- wheels have spun up
30
How does autobrakes apply braking after touch down?
A small amount after touchdown, then scheduled amount once less than 1deg of pitch angle
31
How disengage autobrakes on landing? (4)
- man braking
- turn switch to off or disarm
- speed brake lever moved down
- throttles moved forward
32
Which brake systems have anti-skid?
All 3
33
Which wheels receive anti-skid pairing in alt system?
lateral pairs
34
Does normal/reserve system provide anti-skid for individual wheels?
Yes
35
What does BRAKE SOURCE light mean?
Both normal and alt systems pressures are low
