back course
名詞
(aviation) The approach course formed by the rear lobe of the signal pattern of a localizer antenna array (the portion of the localizer signal emitted from the rear face of the antenna array), oriented in the reciprocal direction to the primary approach course (i.e., the back course - if a usable back course exists at all - will be rotated 180° from the primary course). Not all localizers produce a usable back-course signal; newer equipment radiates very little signal into the rear and side lobes, not enough to allow for a back-course approach.
日本語の意味
航空における、局定位信号のアンテナアレイの背面（リアローブ）から発せられる信号によって形成される進入経路。一次進入コースの逆方向（180°反転）に位置している。
