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)'.

 | 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.
