(2)
Move the moist wad (or pad) lightly across the surface of the screen (one time only).
(3)
If you find again marks or dust on the screen, do steps (1) and (2) again with a new piece of moist wad (or pad). Do these steps again until the screen is fully clean.
NOTE : Use a new pad (or wad) each time to prevent scratches that can
____
be caused by a dusty pad.
(4) Dry the screen with a clean wad (or pad). To do this, move the clean wad (or pad) lightly across the surface of the screen (one time only).
NOTE : We recommend to frequently clean the screen to remove finger
____
marks or dust.

**ON A/C 001-049, 051-099, 101-105, 151-199, 201-212,
The Flight Management and Guidance Computer (FMGC) is a digital computer to
8MCU in conformity with ARINC Specification 600.
(Ref. Fig. 001)
It is to be noted that some boards in the computer are equipped with a
memory module (Five memory modules). The access to these modules is from the
outside of the unit.
The computer consists of two separate parts : a command channel and a
monitoring channel.
(Ref. Fig. 002)
The command channel ensures two functions : the management of the flight and
the guidance.
The monitoring channel only ensures the guidance function.
The two channels are physically separate :
-each channel has its own power supply unit.
-
the electronic boards assigned to each channel are located in different zones in the computer unit.
-
the electrical routings are separate.
-
the pin connections at the output connectors are duplicated and separate.
At software level, the programming languages of the command and monitoring
channels are different.
For the GUIDANCE function, the engage logic of the AP, FD and A/THR systems
in command and monitoring channels is achieved in hard-wired circuitry.

The Flight Management and Guidance Computer (FMGC) is a digital computer to
8MCU in conformity with ARINC Specification 600.
(Ref. Fig. 001A)
It is to be noted that some boards in the computer are equipped with a
memory module (three memory modules). The access to these modules is from
the outside of the unit.
The computer consists of two separate parts : a command channel and a
monitoring channel.
(Ref. Fig. 002A)
The command channel ensures two functions : the management of the flight and
the guidance.
The monitoring channel only ensures the guidance function.
The two channels are physically separate :
