视觉民航ACR与气压基准两部视频勘误及课件下载

2024年12月和2025年5月飞机性能现代化工作室编制了《机场道面强度报告格式ACR-PCR方法》和《高度表拨正和气压基准》的两部视频，并在民航局官网“视觉民航”栏目发布，后续收到读者反馈视频部分内容有误，经对比核实，确认视频有两处错误。现针对这两处错误进行勘误。

对读者造成的不便表示歉意，同时对指出PCR格式错误的山东航空王步卓、顺丰航空李海永，指出低温修正公式错误的内蒙古监管局魏诚表示感谢。

《机场道面强度报告格式ACR-PCR方法》

课件链接：https://www.caac.gov.cn/ZGMHJSP/SJMH/202412/t20241225_226236.html

在《机场道面强度报告格式ACR-PCR方法》视频的4:23处关于经验评定显示的内容为：
“F-经验评定”
此处存在错误，应为：
“U-经验评定”。

《高度表拨正及气压基准》

课件链接：https://www.caac.gov.cn/ZGMHJSP/SJMH/202505/t20250519_227534.html

在《高度表拨正及气压基准》视频的8:12处关于低温修正-准确计算显示的内容为：
此处存在错误，应为：

附录

附录A：低温修正公式说明

错误的低温修正公式出自ICAO Doc 8168第III卷第2篇第4章4.3.4.1节，对应国内咨询通告AC-91-FS-041《航空器运行航空器操作程序》。
正确的低温修正公式出自ICAO Doc 8168第II卷第III部分，第3篇第4章附录A.1.3，对应国内咨询通告AC-97-FS-005R1《航空器运行目视和仪表飞行程序设计规范》。
附录B：详细公式推导
飞机性能现代化工作室之前曾发表过《离地几何高度与气压高度之间的转换》文章，推导了低温修正的公式为：
式中，hg为几何高度，hp为气压高度，ΔT为温度偏差，λ为大气温度垂直递减率1.9812℃/1000ft，TISA,hp为气压高度hp处的标准大气温度，TISA,helev为机场标高helev处的标准大气温度。
根据ICAO Doc 8168文件中的符号习惯，几何高度与气压高度的高度差Δhg-Δhp用Δh表示，温度偏差用ΔTSTD，大气温度垂直递减率使用符号L0，因此上面的低温修正公式表示为
再将飞机与机场高度的温度用标准大气海平面温度t0、大气温度垂直递减率L0与气压高度表示，可得
又因为飞机气压高度hp飞机=hp机场+Δhp，有：
