________________________________________________
1. General
_______
R **ON A/C 001-049, 051-099, 101-149, 151-199, 201-299, 401-499,
(Ref. Fig. 001, 002)
The Position and Warning sub-system has two parts which are:
-Indicating and Warning (Ref. 32-61-00)
-L/G Built-in Test Equipment (BITE) (Ref. 32-69-00).
**ON A/C ALL
A. Indicating and Warning
The proximity sensors on the L/G and L/G doors give position data to the two Landing Gear Control and Interface Units (LGCIUs) (Ref. 32-31-00). There are two sets of proximity sensors. The sensors in System 1 supply data to LGCIU 1 and the sensors in System 2 supply data to LGCIU 2. Each LGCIU sends the position data to the Electronic Instrument System (EIS) (Ref. 31-60-00). The EIS includes the Engine/Warning Display (EWD) (Ref. 31-66-00) and the System Display (SD). Together these make the Electronic Centralized Aircraft Monitoring (ECAM).
The position of each L/G and L/G door shows on the WHEEL page of the SD. If specified failures (or incorrect L/G configurations) occur, the E/WD gives a warning or caution message. Also, the Master Warning, or Caution lights, come on and an aural warning operates (Ref. 31-50-00).
The downlock indicator lights also show the position of each L/G (but not the L/G doors). The downlock indicator lights for the MLG and NLG are independently supplied through LGCIU 1.
Position information is described in Landing Gear Position Information (Ref. 32-62-00).
The LGCIU's supply L/G position data to other aircraft systems. Two types of data are given. These are:
-discrete logic signals
-ARINC 429 data.
The discrete outputs are sent when the L/G is in specified positions
(e.g. L/G locked down). ARINC 429 data is sent all the time when an LGCIU is in operation.
