Here's an example of a Radio Range approach at Joliet (
About Us - scroll down) where the final approach course was not aligned with a range leg - I presume the legs were aligned with airways.
I remember I had enough trouble with tracking outbound from an NDB on a straight approach. The idea of turning through nearly 60 degrees at the beacon to track to the airport only 3 miles away gives me the creeps
I have often wondered how the A and N sectors were propagated. Can anyone enlighten me on how it worked electronically?
