Landing Gear Flashcards
(30 cards)
Why are there two triangles for each gear on the ECAM WHEEL page
Each triangle represents the gear position detected by one of the two LGCIUs
The landing gear hydraulic safety valve is controlled by
The gear lever and ADIRUs 1 and/or 3
Which statement is true concerning the green hydraulic system as it relates to normal landing gear extension
Hydraulic system remains pressurized with gear extended
The landing gear extension and retraction is controlled electrically by
LGCIU 1 or 2
With the gear NOT down, what causes the red landing gear DOWN arrow to illuminate
RA < 750 feet with power at approach settings and flaps not 0
The landing gear DOWN arrow illuminates red with associated ECAM L/G GEAR NOT DOWN warning if the landing gear is not down and
Flaps 3 or FULL selected with both radio altimeters inoperative
According to the graphic what is the position of the landing gear
One LGCIU has failed and the gear is downlinked
What is a characteristic of landing gear gravity extension
Noswheel steering is deactivated
Which landing gear system is lost with a green hydraulic failure
Nose wheel steering
With a green hydraulic system failure only, which brake system is not available
Autobrakes
How do you stop an airplane with a failed parking brake, during engine start
Restore braking with the brake pedals
What happens if the A/SKID & N/W STRG switch is turned off
Brakes revert to the alternate brake system without nose wheel steering or anti skid
A brake accumulator supplies at least _____ brake applications
7
Which hydraulic systems provides pressure for the ALTERNATE brakes
Yellow
Which hydraulic system is used for the parking brake
Yellow
Which hydraulic system provides brake pressure indications on the BRAKES and ACCU PRESS indicator
Yellow
What pilot action is required on landing with a loss of normal braking and a failure of the anti skid system
Monitor the brake pressure using the BRAKES and ACCU PRESS indicator
What type of brakes are available with only a green hydraulic failure
Alternate brakes with anti skid
When alternate braking is available without antacid due to a BSCU failure, pedal pressure must be controlled to prevent wheel lockup and
Brake pressure must be limited to a maximum of 1000 PSI on the BRAKES and ACCU PRESS indicator
The anti skid system is deactivated with
Groundspeed less than 20 knots
Which system is not active if a takeoff is rejected below 72 knots
Autobrakes
The BSCUs control
Antiskid operation
Which hydraulic systems supplies pressure for nose wheel steering
Green
What does the green NW STRG DISC ECAM memo indicate
A lever on the towing electrical box is in the towing position and the nose wheel steering system is deactivated
