They | indicate the true condition of the | corresponding data word bit position. There are two states: | bit status 0 or bit status 1. | The third one is related to the ARINC 429 | Discrete Data Words. | The second one, with no specific indication, | shows the normal operational range of the | parameter. This | depends on the number of data bits (see | column DATA BITS) and the resolution (R) of | the parameter (see column ACCURACY). Column | Description -|-| can be transferred on the bus. This | shows the maximum value of the parameter that | 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. The columns are described as follows: -Column | Description -|-1st | EQ. = Parameternumber | | 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. 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. Explanations to the Parameter List The parameter list is organized according to the connected ARINC 429 data buses.
