English
Noun
back course (plural back courses)
- (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 produced in usable form by all localizers, with newer equipment radiating very little signal into the rear and side lobes (not enough to allow for a back-course approach).
