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.

Column | Description
----------------|-----------------------------------------------| 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)'.
---------------|----------------------------------------------7th | UPD/sec
UPD/sec | | This column shows how many times the | parameter will be transmitted by the source | system per second.
---------------|----------------------------------------------8th | CODE
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.
