-
between the selection of DOWN or 800 ft radio height (whichever is the first to occur) and the second engine shut down.
The L/G position-indicator lights (8GB/9GB/10GB) show the position of the MLG and NLG.
At the start of a L/G retraction sequence with the L/G control-lever (6GA) set to UP:
-
the red indicator lights come on
-
the green indicator lights stay on.
The green indicator lights stay on until a L/G doors fully open signal causes the LGCIU to signal the L/G to retract. This releases the downlocks.

The paragraphs that follow describe:
-
the conditions that cause each warning message
-
the visual and aural warnings and system indications given with each message.
(1) LGCIU 1 (2) FAULT
This warning message and the WHEEL page shows if during flight:
-
a LGCIU failure occurs
-
a failure occurs in the LGCIUs L/G control and position sensing system (e.g. an electrical failure of a proximity sensor).
When these failures occur the WHEEL page shows two amber X legends at each L/G indication position.
NOTE : The WHEEL page also shows these legends when the aircraft is
____ flown with LGCIU2 not in operation because the LGCIU2 CB is opened (Refer to the MMEL).

(a)
If a shock absorber does not extend (as detected by both SYSTEM 1 and SYSTEM 2).
(b)
If a shock absorber did not compress when the aircraft was on the ground (as detected by both SYSTEM 1 and SYSTEM 2) the warnings as specified above occur.
(c)
If a shock absorber does not fully extend during a retraction cycle (as detected by both SYSTEM 1 and SYSTEM 2):
-
the retraction cycle stops
-
the warnings as specified above occur immediately.
1_ The movement of the L/G control-lever to UP is baulked.
2_ 5 seconds after the aircraft enters flight phase 5 the failure
warning message L/G SHOCK ABSORBER FAULT shows (on the upper
ECAM DU) and:
- the master caution (amber) lights come on
- a single chime sounds.
NOTE : If SYSTEM 1 and SYSTEM 2 do not agree on shock absorber
____ extension (as signalled by the proximity sensors), the selection of L/G UP is not baulked.
(3) L/G NOT DOWNLOCKED, L/G NOT UPLOCKED, L/G DOOR NOT CLOSED
When one or more of the L/G or L/G doors do not lock (or stay locked) in the selected position (as detected by both SYSTEM 1 and SYSTEM 2):
-
the applicable warning message shows
-
the applicable red master warning or amber caution light comes on (red for L/G not down and locked, and amber for the other conditions)
-an aural warning sounds (a continuous repetitive chime with the red master warning lights or a single chime with the amber caution lights)
-
the WHEEL page shows (if a L/G does not downlock, the selection of DOWN will cause the WHEEL page to show).
When the warning messages L/G NOT DOWNLOCKED or L/G NOT UPLOCKED show, the WHEEL page shows:
-
the message L/G CTL
-two red triangles at the applicable L/G indication position(s).
1EFF : ALL 1 32-61-00Page 37 1 1 Feb 01/05 1 1 1CES 1 When the warning message L/G DOOR NOT CLOSED shows, the WHEEL page shows, an amber bar. This is for applicable L/G door indication position(s).
If a L/G does not lock in the selected position (as detected by SYSTEM 1) the applicable red indicator light (402VU panel) stays on.
(4) L/G NOT DOWN - L/G Configuration Warning
The FWCs and ECAM supply the L/G configuration warning L/G NOT DOWN.
