Column | Description
----------------|-----------------------------------------------| shows the maximum value of the parameter that | can be transferred on the bus. This | depends on the number of data bits (see | column DATA BITS) and the resolution ('R') of | the parameter (see column ACCURACY). | The second one, with no specific indication, | shows the normal operational range of the | parameter. | The third one is related to the ARINC 429 | Discrete Data Words. There are two states: | 'bit status 0' or 'bit status 1'. They | indicate the true condition of the | corresponding data word bit position.
---------------|----------------------------------------4th | ACCURACY
ACCURACY |
| Two different types of values are shown
| in this column:
| The first one, indicated by an 'R'
| (RESOLUTION) is related to the ARINC
| 429 data bus. It also shows the
| resolution of the data word. The second
| one, with no specific indication, shows
| the total accuracy of the parameter.
---------------|-----------------------------------------5th | SIGN BIT
SIGN BIT |
| This column shows whether a sign bit
| is available and in which bit position
| of the data word it is situated.
---------------|-----------------------------------------6th | DATA BITS
DATA BITS |
| Describes the number of data bits not
| including the sign bit. 'A' and a number
| means the discrete bit position in the
| ARINC 429 data word.
| For BCD coded data words the number of
| significant data digits is shown,
| indicated by '(1)'.

CODE |
| BNR = binary data word
| BCD = binary coded decimal data word
| ISO = data word coded in ISO 5 Code
| DIS = discrete data word
| HEX = hexadecimal coded
| OCT = octal coded
| HYB = mixed code;
| e.g. : bit 11 to 16 DIS
| bit 17 to 28 BNR
---------------|----------------------------------------------9th | ALPHA CODING
ALPHA CODING |
| This column shows the mnemonic for the
| parameter (if available). By entering
| this code via the MCDU, the current
| parameter-value will be shown on the
| display. The value from both systems
| (if available) will be shown.
