It’s been a long time since I had to tackle this issue , but I know from the early days of IFR training that you can have up to 110 degrees intercept angle with respect to the final approach course to be eligible to turn in and track the inbound course . It’s been suggested recently though that this is wrong and that the maximum intercept angle is 90 degrees . Anything more would require holding entry first to properly align you with the final approach course . At the end which of the 2 angles is valid ? I did a brief web search but no concrete statements found on this regard.
If you do know the answer can you please indicate the source?
thank you
