-two triangles that show the L/G position (one triangle for each LGCIU system)
-a moving hinged bar that shows the L/G door position.
The triangles are:
-green when the L/G is down and locked
-red when the L/G is in transit
-not in view when the L/G is up and locked.
A green triangle will always be more important than a red
triangle. Thus a green triangle shows as the front triangle.
The hinged bars are:
-green when the door is closed
-amber when the door is not closed.
An amber indication, L/G CTL shows when the L/G is not locked in
its set position.
(b) Failure Indications
When specified failures occur the WHEEL page shows (in amber):
-the indication UPLOCK (above the applicable L/G and L/G door indicator)
-X legends. Two X legends can replace each L/G or L/G door
indicator. The failure conditions that cause the indication/legends to show are given in paragraph 7.B. L/G System Warnings.

(1) ECAM WHEEL Page
The ECAM system uses L/G position data to give the WHEEL page display on the lower ECAM DU. The data from the two systems is used to make an analysis, to give these indications:
(a) Normal Indications
The ECAM WHEEL page shows three sets of colored indicators. Each set of indicators has:

-two triangles that show the L/G position (one triangle for each LGCIU system)
-a moving hinged bar that shows the L/G door position.
The triangles are:
-green when the L/G is down and locked
-red when the L/G is in transit
-not in view when the L/G is up and locked.
A green triangle will always be more important than a red triangle. Thus a green triangle shows as the left triangle and a red triangle shows as the right triangle.
The hinged bars are:
-green when the door is closed
-amber when the door is not closed.
An amber indication, L/G CTL shows when the L/G is not locked in its set position.
(b) Failure Indications
When specified failures occur the WHEEL page shows (in amber):
-the indication UPLOCK (above the applicable L/G and L/G door indicator)
-X legends. Two X legends can replace each L/G or L/G door
indicator. The failure conditions that cause the indication/legends to show are given in paragraph 7.B. L/G System Warnings.

(2) L/G Position Indicating Light Units (8GB/9GB/10GB).
The three sets of indicator lights are installed in 402VU panel. This panel is on the main instrument panel above the L/G control-lever (6GA). Each set of indicator lights shows the position of a single L/G as follows:
-red, L/G not locked in the selected position
-green, L/G down and locked.

The red DOWN arrow has internal lighting. This comes on when the L/G is not extended and the engines and flight controls are in a landing configuration.

A. Normal System Indications
The L/G and L/G door indicators on the WHEEL page show the position of the L/G and the L/G doors. The WHEEL page automatically shows:
