IEC 62131的这一部分审查了与旋翼机（直升机）运输电工设备有关的可用动态数据。目的是从所有可用数据中生成环境描述，并与IEC 60721（所有部分）[16]1中规定的环境描述进行比较。 对于每一个确定的来源，都会对数据的质量进行审查，并检查其自身的一致性。IEC TR 62131-1[21]中规定了用于进行数据质量检查以及用于对各种数据源进行本质分类的过程。 本文件主要讨论从许多不同来源提取的数据，这些数据的质量和有效性具有合理的可信度。 本文件还审查了一些无法实际验证其质量和有效性的数据。包括这些数据是为了便于验证其他来源的信息。本文件明确说明了如何利用后一类信息。 本文件介绍了一些数据收集练习中的数据。这些练习中数据的数量和质量差异很大，所包含的条件范围也不同。 并非所有审查的数据都以电子形式提供。为了进行比较，在本次评估中，对大量原始（非电子）数据进行了手动数字化。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This part of IEC 62131, reviews the available dynamic data relating to the transportation of electrotechnical equipment by rotorcraft (helicopters). The intent is that from all the available data an environmental description will be generated and compared to that set out in IEC 60721 (all parts) [16]1. 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 [21]. This document primarily addresses data extracted from a number of different sources for which reasonable confidence exist in its quality and validity. This document also reviews some data for which the quality and validity cannot realistically be verified. These data are included to facilitate validation of information from other sources. This document clearly indicates when utilizing information in this latter category. This document addresses data from a number of data gathering exercises. The quantity and quality of data in these exercises varies considerably as does the range of conditions encompassed. Not all of the data reviewed were made available in electronic form. To permit comparison to be made, in this assessment, a quantity of the original (non-electronic) data has been manually digitized.All current amendments available at time of purchase are included with the purchase of this document.
