摘　　要：在划设最低监视引导高度时,由于部分终端区区域较大,导致距离中心机场较远的区域存在气压高度误差,影响航空器的飞行安全。通过对终端区内最低引导气压高度的高度误差进行分析,并对ICAO和飞机制造商温度修正算法进行比较,最终选择ICAO的修正算法进行修正。根据我国目前的超障余度规定,针对较大终端区内距离中心机场较远的山区区域进行修正。以乌鲁木齐终端区为实例进行验证,说明了修正的必要性,提出了相关规律,并可以利用算法检查划设终端区内各扇区最低监视引导高度是否满足要求。When setting the minimum vector altitude,some of the terminal areas are large,resulting in errors in areas far from the central airport,which affects aircraft flight safety.By analyzing the altitude errors of the barometric altimeter and comparing the ICAO and aircraft manufacturer′s temperature correction algorithms,the ICAO correction algorithm was selected to correct for the errors in mountainous areas far from the central airport within the larger terminal area.Finally,using the Urumqi terminal area as an example for validation,the necessity of the correction is illustrated,the relevant laws are proposed and the algorithm in the text can be used to check whether the minimum vector altitude for each sector within the delineated terminal area meets the requirements.
