_____________________________________________________________________________ | EQ | ARINC 429 equipment identification: | | | two-digit hexadecimal character e.g. 1B (for SFCC) | |-----------|---------------------------------------------------------------| | SYS | System Number: | | | one character (only 1 to 4) | |-----------|---------------------------------------------------------------| | LAB | ARINC 429 Label: | | | three-digit octal character (valid entries 000 - 377) | |-----------|---------------------------------------------------------------| | SDI | Source Destination Identifier: | | | valid entries 00, 01, 10, 11 and XX (XX represents a case in | | | which the DMU samples the parameter without looking at the | | | SDI field) | |-----------|---------------------------------------------------------------| | DATABITS | Identifies which ARINC 429 bits to extract from the label | | | call-up parameter and show as decimal value (valid entries | | | 1 to 20) | |-----------|---------------------------------------------------------------| | VALIDITY | Validity of the requested parameter: | | | '>' parameter has not been transmitted/updated. | | | 'Blank' parameter has been updated. | |-----------|---------------------------------------------------------------| | SSM | Sign Status Matrix: | | | is taken from bits 31 to 29 of the parameter and shows in | | | binary form. | |-----------|---------------------------------------------------------------| | DECIMAL | Decimal value of the parameter calculated using the 'DATABITS'| | VALUE | entry to specify the number of bits to use as data. The | | | decimal value is calculated assuming the extracted data bits | | | as a whole represent a 2's complement value. For example | | | 'DATABITS' of 12 results in the decimal display of ARINC 429 | | | bits 28 to 17 . A 'DATABITS' entry of 20 results in a decimal | | | display of ARINC 429 bits 28 to 09. If bit 29=0, then the | | | decimal equivalent of the two complement of the 'DATABIT' | | | value will be preceded with a negative sign. | |-----------|---------------------------------------------------------------| | BINARY | Binary Data (bits 28 to 11) of the parameter are shown on the | | DATA | on the line below the label 'DATABITS 28-11'. | -----------------------------------------------------------------------------

For all the parameters, which are listed in the alpha call-up table. The selection is possible by their alpha codes. If parameters from two systems are available, both parameters are displayed on the MCDU upon a single alpha call-up code entry. The displayed parameter values are refreshed once per second. All numeric type alpha call-up parameters are displayed on the MCDU in engineering units. The display format is a floating point representation of max. 6 characters including the decimal point and the '-' sign if applicable. In case of positive numbers without decimal point all 6 characters are available for digits. Display of loading zeros are suppressed. The applicable units are shown below the alpha call-up code on the MCDU screen. Alpha call-up parameters, which consist of a combination of several discrete bits or packed discretes are displayed in hexadecimal representation. In this case the indication of the applicable units of the parameter are 'HEX'. 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：A320飞机维护手册 AMM 指示/记录系统 3(36)
