A. Explanations to the Parameter List The parameter list is organized according to the connected ARINC 429 data buses. The connected systems (e.g. FAC, ECU, EEC, etc.) and the corresponding ATA chapter numbers are stated in the header on the left side of each page of the parameter lists. The columns are described as follows:
----------------------------------------------------------------Column | Description ---------------|------------------------------------------------1st | EQ.SYS.LAB.SDI = Parameternumber
SYS.LAB.SDI | | System number: According to the system which is | sending out the corresponding parameter: | 1 for system one | 2 for system two | 3 for system three | Label of the parameter, octal value | according to ARINC 429. | SDI states the Source/Destination Identifier | which is used by the system for the | corresponding parameter: | 00 means SDI 00 (0) | 01 means SDI 01 (1) | 10 means SDI 10 (2) | 11 means SDI 11 (3)
---------------|------------------------------------------------2nd | PARAMETER PARAMETER | Parameter name ---------------|------------------------------------------------3rd | RANGE
RANGE | | Three different types of ranges are shown in | this column: | The first one, indicated by a 'W' (WORDRANGE), | is related to the ARINC 429 data bus. This | shows the maximum value of the parameter that | can be transferred on the bus. This
----------------------------------------------------------------
Column | Description ---------------|------------------------------------------------
| 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
