LANDING GEAR INDICATOR PANEL
Applicable to: ALL
This panel is connected to LGCIU1, which receives signals from proximity detectors.
UNLK: come on red if the gear is not locked in the selected position.
◂ : come on green if the gear is locked down.
Note: The lights on the LDG GEAR indicator panel come on as long as the LGCIU1 is electrically
supplied.
LANDING GEAR SELECTOR LEVER
Applicable to: ALL
A two-position selector lever sends electrical signals to the two LGCIUs. These control the green
hydraulic supply to the landing gear system by means of selector valves.
When the flight crew selects UP or DOWN (and if the airspeed is below 260 kt) :
‐ All landing gear doors open.
‐ Each landing gear moves to the selected position.
‐ All landing gear doors close.

(1) L/G LEVER
UP : This position selects landing gear retraction.
While the landing gear doors are opening, the normal brake system brakes the
wheels of the main gear automatically.
DOWN : This position selects landing gear extension.
An interlock mechanism prevents anyone from accidentally retracting the gear
while the aircraft is on the ground. It does so by locking the lever in DOWN position
when the shock absorber on either main gear is compressed (aircraft on ground) or
the nose wheel steering is not centered.
The landing gear hydraulic system remains pressurized as long as the landing gear
is extended (if green hydraulic pressure is available).
(2) RED ARROW
This red arrow lights up if the landing gear is not locked down when the aircraft is in the landing
configuration, and a red warning appears on ECAM.

EMERGENCY EXTENSION
Applicable to: ALL
To put the landing gear down by gravity, the flight crew must pull the gear crank out, then turn it
clockwise for 3 turns.
When the flight crew operates the crank handle, the cutout valve shuts off hydraulic pressure to the
landing gear system and depressurizes it.

Applicable to:
(1) Landing gear position indication
The landing gear positions are indicated by 2 triangles for each gear.
Each triangle is controlled by one LGCIU :
a green triangle indicates that one LGCIU detects ‐ a landing gear downlocked,
‐ a red triangle indicates that one LGCIU detects a landing gear in transit,
‐ no triangle indicates that one LGCIU detects a landing gear uplocked,
‐ amber crosses indicates that one LGCIU is failed.
