What is the maximum coupled intercept angle for LOC BC?

The maximum coupled intercept angle for a Localizer Back Course (LOC BC) approach in the King Air 350 is 70 degrees. This angle refers to the maximum angle at which the aircraft can effectively intercept the back course of the localizer signal while maintaining controlled flight and good performance.

An intercept angle of 70 degrees allows for adequate guidance from the localizer, ensuring that the aircraft remains stabilized and accurately aligned with the approach path. Beyond this angle, the risk of undesirable aircraft behavior increases, which can complicate the approach and affect safety.

In the context of approach procedures, adhering to this maximum intercept angle is critical for training and operational compliance, ensuring pilots can successfully execute LOC BC approaches without encountering issues related to excessive angles which might not allow for proper capture of the localizer signal.
