Landing Gear And Brakes Flashcards
Which hydraulic system powers the landing gear?
A
Why are there two sets of gear indication lights?
The second one is a redundant but separate system
How is the main landing gear held up and locked?
After retraction, the main gear are held in place by mechanical uplocks
How is the main landing gear held down and locked?
Overcenter mechanical and hydraulic locks hold the gear at full extension.
How is the landing gear extended?
landing gear extends by hydraulic pressure, gravity and air loads.
If Hydraulic System A is unavailable, how can the gear be extended?
Manual gear extension
With the Manual Release System door open, can the gear be retracted?
- close the manual extension access door
- move the LANDING GEAR lever to DOWN with hydraulic system A pressure available, and then • position the LANDING GEAR lever to UP.
What powers the brakes and the alternate brakes?
Normal brakes - B
Alternate system - A
Is anti-skid available for both brake systems?
Yes
If normal and alternate brake pressure is lost, is braking still possible?
If both normal and alternate brake system pressure is lost, trapped hydraulic pressure in the brake accumulator can still provide several braking applications or parking brake application.
Is autobrake available when operating with the Alternate Braking System?
NO
At what speed does the Autobrake System arm on the ground?
90 kts
What is the maximum available braking?
Max manual
What disarms the Autobrake System once braking has started?
- moving the SPEED BRAKE lever to the down detent
- advancing the forward thrust lever(s), except during the first 3 seconds after touchdown for landing
- applying manual brakes
What indication might a pilot receive if there a fault in the brake system?
Auto brake disarm light if you select the autobrakes
