scope:

IEC/TR 62131-2, which is a technical report, reviews the available dynamic data relating to electrotechnical equipment transported in fixed wing jet transport aircraft. The intent is that from all the available data an environmental description will be generated and compared to that set out in IEC 60721.

For each of the sources identified the quality of the data is reviewed and checked for self consistency. The process used to undertake this check of data quality and that used to intrinsically categorize the various data sources is set out in IEC/TR 62131-1.

This technical report primarily addresses data extracted from a number of different sources for which reasonable confidence exist as to their quality and validity. The report also presents data for which the quality and validity cannot realistically be reviewed. These data are included to facilitate validation of information from other sources. The report clearly indicates when it utilizes information in this latter category.

This technical report addresses data from several different transport aircraft1. Although one of these aircraft is no longer used commercially, data from it are included to facilitate validation of information from other sources.

Relatively little of the data reviewed has been made available in electronic form. To permit comparison, a quantity of the original (non-electronic) data have been manually digitized in this technical report.
